Aortic stenosis is the most important valvular heart disease affecting the elderly population. Surgical aortic valve replacement
is the mainstay of treatment, although a substantial number of patients are considered high risk for surgery. Many of these
patients do not undergo surgery and have poor outcomes from medically treated symptomatic, severe aortic stenosis. Transcatheter
aortic valve implantation (TAVI) provides a promising treatment option for some of these patients. Several devices are under
investigation. The Edwards Sapien valve (Edwards Lifesciences, Irvine, CA) and the CoreValve (Medtronic, Minneapolis, MN)
have the largest human experience to date. Initial data suggest that these devices have an acceptable safety profile and provide
excellent hemodynamic relief of aortic stenosis. The Edwards Sapien valve is currently under investigation in the United States
in the PARTNER (Placement of Aortic Transcatheter Valve) trial in high-risk surgical or inoperable patients; TAVI is available
for clinical use in both Canada and Europe. TAVI is not used in low- or intermediate-risk surgical patients; however, future
studies may prove its applicability in these subsets. The major complications of TAVI include access site-related problems
and device malpositioning/migration. There are several new-generation prosthetic valves and delivery systems designed to be
low profile and repositionable. Technical advances and refinement of the implantation methods may make TAVI even safer and
ultimately a better treatment option, not only for patients with high surgical risk but also for those with moderate or low
risk. 相似文献

Objectives: To describe results from a novel percutaneous technique designed to minimize the risk of hemorrhage in the event of a major complication during transcatheter aortic valve implantation. Background: Vascular access management is a major challenge in transfemoral TAVI due to the large introducer sheathes required. Methods: Fifty‐two pts underwent TAVI between November 2007 and March 2009. Of these, 37 received an Edwards‐Sapien Valve (23 mm valve: 17/37; 26 mm valve: 20/37) whilst 15 patients received a CoreValve (26 mm valve: 6/15; 29 mm valve: 9/15). Using a crossover technique, the opposing femoral artery was cannulated with a 7Fr long sheath. This allowed contralateral passage of a balloon and inflation in the proximal iliac. The sheath was then removed and Prostar sutures tied in a dry field. Balloon optimization of the puncture site was performed as required. Results: In three subjects, elective surgical repair was undertaken due to excessive femoral arterial calcification. In the remaining 49, the crossover technique was employed and closed with two Prostar devices (Edwards‐Sapien) or one (CoreValve). There were serious “on‐table” complications in seven patients, six due to the large introducer sheathes used in the TAVI procedure—iliac avulsion, two iliac dissections, iliac perforation, common femoral perforation and scrotal hematoma. All were repaired safely by combined surgical and endovascular techniques, using the crossover technique to ensure patient stability. All made a good recovery and were independently ambulant at discharge. Conclusion: Using crossover balloon inflation as an adjunct to Prostar closure may be helpful for managing TAVI vascular access sites. © 2009 Wiley‐Liss, Inc. 相似文献

Objectives
To evaluate the feasibility of coronary procedures after transcatheter aortic valve implantation (TAVI) with the CoreValve? device.Background
Due to its design, CoreValve? prosthesis may interfere with coronary procedures. Data on this issue are sparse.Methods
Between 2007 and 2015, 550 patients underwent CoreValve? TAVI in our hospital. Among them, 16 underwent coronary angiogram after TAVI and were included in our retrospective study. For each patient, we compared the characteristics of coronary angiograms performed before and after TAVI.Results
Coronary angiogram was deemed successful in 9 patients. The mean number of different catheters used in attempts to cannulate the coronary arteries was 3.6 ± 1.4 and the rate of selective intubation was low. Fluoroscopy time (13.2 ± 5.8 vs. 7.2 ± 4.6 min, P = 0.003), dose area product (5,347 ± 4,919 vs. 3,433 ± 3,420 cGy/m2, P = 0.004), and contrast volume (157.7 ± 69.6 vs. 108.3 ± 42.6 mL, P = 0.006) were more important in coronary angiograms performed after CoreValve? implantation. Percutaneous coronary intervention was successfully performed in 6 out of 7 patients who required it.Conclusion
Coronary procedures after CoreValve? TAVI are feasible, but challenging. This problem is currently rare but will be more common as the indications of TAVI are expanded to younger patients with longer life expectancies. Recommendations for post‐TAVI coronary procedures are needed, particularly for centers unfamiliar with the management of post‐TAVI patients.4.

Atrioventricular (AV) conduction impairment is well described after surgical aortic valve replacement, but little is known in patients undergoing transcatheter aortic valve implantation (TAVI). We assessed AV conduction and need for a permanent pacemaker in patients undergoing TAVI with the Medtronic CoreValve Revalving System (MCRS) or the Edwards Sapien Valve (ESV). Sixty-seven patients without pre-existing permanent pacemaker were included in the study. Forty-one patients (61%) and 26 patients (39%) underwent successful TAVI with the MCRS and ESV, respectively. Complete AV block occurred in 15 patients (22%), second-degree AV block in 4 (6%), and new left bundle branch block in 15 (22%), respectively. A permanent pacemaker was implanted in 23 patients (34%). Overall PR interval and QRS width increased significantly after the procedure (p <0.001 for the 2 comparisons). Implantation of the MCRS compared to the ESV resulted in a trend toward a higher rate of new left bundle branch block and complete AV block (29% vs 12%, p = 0.09 for the 2 comparisons). During follow-up, complete AV block resolved in 64% of patients. In multivariable regression analysis pre-existing right bundle branch block was the only independent predictor of complete AV block after TAVI (relative risk 7.3, 95% confidence interval 2.4 to 22.2). In conclusion, TAVI is associated with impairment of AV conduction in a considerable portion of patients, patients with pre-existing right bundle branch block are at increased risk of complete AV block, and complete AV block resolves over time in most patients. 相似文献

Objectives: To evaluate feasibility and outcome of Transoartic Transcatheter Sapien valve implantation. Background: Transcatheter Aortic valve implantation (TAVI) using the Edwards SAPIEN device (Edwards LifeScience, Irvine, CA) is usually performed via the transfemoral (TF) or transapical (TA) routes. Some patients are not suitable for these approaches. We report our experience with the novel transaortic (TAo) approach via a partial upper sternotomy and discuss the advantages and future applications. Methods: Between January 2008 to March 2011 193 patients with severe aortic stenosis underwent TAVI with the Edwards SAPIEN bioprosthesis at the St. Thomas' Hospital, London. 108 patients were unable to undergo a TF‐TAVI and of those 17 were accepted for a TAo‐TAVI on the basis of anatomy, risk, LV function, and significant respiratory disease. Results: The TAo‐TAVI group (n = 17) had more prevalent respiratory disease than the TA‐TAVI group (47.0% vs. 18.7%, P = 0.011). Otherwise the groups were similar in demographics and history. Despite this the 30 day mortalities were not significantly different between the groups (TAo‐TAVI 4.3% at 30 days versus TA‐TAVI 7.7%, P = 0.670). There were no significant differences in procedural complications. Conclusions: The TA‐TAVI approach may not be desirable in patients with severe chest deformity, poor lung function or poor left ventricular function. TAo‐TAVI via a partial sternotomy is safe and feasible in these patients. © 2011 Wiley Periodicals, Inc. 相似文献

Objectives : The purpose of this study is to verify whether transcatheter aortic valve implantation (TAVI) determined changes in mitral valve (MV) function, in terms of mitral regurgitation (MR) and stenosis. Background : Little data is available regarding the effects of TAVI on global MV function, often derived from analysis primarily focused on clinical and aortic related outcomes. Methods : From May 2008 to March 2010, 73 patients with severe symptomatic aortic stenosis underwent TAVI with the CoreValve ReValving System. The study population consisted of 58 patients (27 males, mean age 82 ± 7 years) who underwent transthoracic echocardiography at least ≥1 month after implantation (mean follow‐up 7.8 ± 5.4 months). Results : In patients with a left ventricular dysfunction (ejection fraction, EF, <45%) at the baseline, EF significantly increased from 37 ± 6% to 48 ± 7% after TAVI (P = 0.003). Before TAVI, 42 patients had no or mild MR, 13 mild‐to‐moderate, and 3 moderate or moderate‐to‐severe. During follow‐up, the MR degree was unchanged in the majority of patients (55%), 12% reduced, and 33% worsened. Variables associated with worsening in MR were depth of aortic prosthesis (P = 0.02 for the distance between the ventricular end and the right coronary cusp; P = 0.04 for mean distance right‐left coronary cusps) and left atrium area at the baseline (P = 0.02). After TAVI, six patients (10%) developed mild or moderate mitral stenosis, often in a native valve with anterior calcifications. Conclusions : In the majority of patients no significant changes occurred in the degree of MR in native valve, but we found that if the aortic valve was deeply implanted in the left ventricle outflow tract, a worsening in MR can be observed. A mitral stenosis development must be sought in patients with heavy calcifications of the anterior leaflet. © 2011 Wiley‐Liss, Inc. 相似文献

Objectives : To assess the acute and intermediate changes in mitral regurgitation (MR) severity after transcatheter aortic valve implantation (TAVI) with the CoreValve Revalving SystemTM (CRS). Background : Following surgical aortic valve replacement, improvement in MR is reported in 27–82% of the patients. The changes in MR severity following CRS implantation are unknown. Methods : Transthoracic echocardiography was performed in 79 consecutive patients before and after treatment, and at the first outpatient visit. Left ventricular dimensions and ejection fraction (LVEF), left atrial (LA) size, and aortic gradient were measured. MR was assessed by color flow mapping and was graded as none, mild, moderate, or severe. It was defined as organic or functional. The depth of CRS implantation was measured by angiography. Results : Post‐treatment, the mean gradient decreased from 48 ± 16 mm Hg to 9 ± 5 mm Hg (P < 0.0001). There was no significant change in the left ventricular dimensions, LA size, and LVEF. MR pretreatment was mild, moderate, or severe in 57%, 18%, and 1% of the patients, respectively. It was defined as organic in 27 patients (36%) and functional in 27 patients (36%). The degree of MR remained unchanged in 61% of the patients, improved in 17%, and worsened in 22%. MR improvement was associated with a lower baseline LVEF (P = 0.02). There was no association between the changes in MR severity and the depth of CRS implantation. Conclusions : Most patients who underwent TAVI had some degree of MR. Overall there was no change in the degree of MR post‐treatment. Patients in whom MR improved had a lower LVEF at baseline. © 2009 Wiley‐Liss, Inc. 相似文献

Background : Low‐flow, low‐gradient aortic stenosis is associated with relevant postoperative mortality whereas conservative management results in dismal prognosis. We present the initial experience of low‐flow, low‐gradient aortic stenosis treated with transcatheter aortic valve implantation (TAVI). Methods : From June 2008 to December 2010 167 consecutive patients with native severe aortic stenosis and an excessive operative risk underwent TAVI. Of these, 15 patients presented with low‐flow, low‐gradient aortic stenosis (aortic valve area < 1 cm2, left ventricular (LV) ejection fraction < 40%, aortic mean gradient < 40 mm Hg). The CoreValve prosthesis 18‐F‐generation (Medtronic, Minneapolis, Minnesota) was inserted retrograde. Clinical follow‐up and echocardiography were performed 6 months after procedure. Results : Patients with low‐flow, low‐gradient aortic stenosis (mean LV ejection fraction 32 ± 6%, mean aortic gradient 27 ± 7 mm Hg) had higher all‐cause mortality 6 months after TAVI compared to patients without low‐flow, low‐gradient aortic stenosis (33% vs. 13%, P = 0.037). In the surviving 10 patients with low‐flow, low‐gradient aortic stenosis, LV ejection fraction increased (34 ± 6% before vs. 46 ± 11% 6 months after TAVI, p = 0.005) and more distance covered in the 6‐minute walk test (218 ± 102 meters before vs. 288 ± 129 meters 6 months after TAVI, p = 0.038). Conclusion : Our study suggests that TAVI is feasible in patients with severe co‐morbidities and low‐flow, low‐gradient aortic stenosis. Within the first 6 months after treatment all‐cause mortality was considerable high, but the surviving patients showed symptomatic benefit and significant improvement of myocardial function and exercise capacity. © 2011 Wiley Periodicals, Inc. 相似文献

Severe aortic stenosis (AS) is a life-threatening condition when left untreated. Aortic valve replacement (AVR) is the gold standard treatment for the majority of patients; however, transcatheter aortic valve implantation/replacement (TAVI/TAVR) has emerged as the preferred treatment for high-risk or inoperable patients. The concept of transcatheter heart valves originated in the 1960s and has evolved into the current Edwards Sapien and Medtronic CoreValve platforms available for clinical use. Complications following TAVI, including cerebrovascular events, perivalvular regurgitation, vascular injury, and heart block have decreased with experience and evolving technology, such that ongoing trials studying TAVI in lower risk patients have become tenable. The multidisciplinary team involving the cardiac surgeon and cardiologist plays an essential role in patient selection, procedural conduct, and perioperative care. 相似文献

BackgroundSelf-expanding transcatheter heart valves (THVs) are associated with better echocardiographic hemodynamic performance than balloon-expandable THVs and are considered preferable in patients with small annuli.ObjectivesThis study sought to compare 5-year outcomes between self-expanding vs balloon-expandable THVs in severe aortic stenosis (AS) patients with small annuli.MethodsConsecutive severe AS patients with an aortic valve annulus area <430 mm2 who underwent transcatheter aortic valve replacement (TAVR) with either the CoreValve Evolut (Medtronic) or SAPIEN (Edwards Lifesciences) THV between 2012 and 2021 were enrolled from the Bern TAVI registry. A 1:1 propensity-matched analysis was performed to account for baseline differences between groups.ResultsA total of 723 patients were included, and propensity score matching resulted in 171 pairs. Technical success was achieved in over 85% of both groups with no significant difference. Self-expanding THVs were associated with a lower transvalvular gradient (8.0 ± 4.8 mm Hg vs 12.5 ± 4.5 mm Hg; P < 0.001), a larger effective orifice area (1.81 ± 0.46 cm2 vs 1.49 ± 0.42 cm2; P < 0.001), and a lower incidence of prosthesis-patient mismatch (19.7% vs 51.8%; P < 0.001) than balloon-expandable THVs. At 5 years, there were no significant differences in mortality (50.4% vs 39.6%; P = 0.269) between groups. Disabling stroke occurred more frequently in patients with a self-expanding THV than those with a balloon-expandable THV (6.6% vs 0.6%; P = 0.030). Similar results were obtained using inverse probability of treatment weighting in the Bern TAVI registry and the nationwide Swiss TAVI registry.ConclusionsThe echocardiographic hemodynamic advantage of self-expanding THVs was not associated with better clinical outcomes compared with balloon-expandable THVs up to 5 years in patients with small annuli.

Background : Transcatheter aortic valve implantation (TAVI) is an emerging alternative to palliative medical therapy for nonsurgical patients with severe aortic stenosis. There is a paucity of detailed data on the management and outcome of complications related to the sub‐optimal deployment of the prosthesis. We appraised the incidence and management of early implant failure occurring during TAVI. Methods : Of 110 patients who underwent TAVI using the third generation 18‐French CoreValve ReValving System (Medtronic, MN) in our Institution between June 2007 and January 2010, we identified those experiencing early implant failure and reported on their management and clinical outcome. The primary endpoint was the incidence of major adverse cardiovascular and cerebrovascular event (MACCE) at 30 days and mid‐term follow up. Results : Early implant failure occurred in 18 of 110 patients (16.3%). The most common cause was prosthesis under‐expansion conditioning moderate to severe peri‐valvular leak (44.4%). Prosthesis deployment too low or too high with respect to the aortic annulus leading to severe peri‐valvular leak occurred in 22.2% and 5.5% of patients, respectively. Need of valve retrieve after the first attempt of deployment occurred in four cases (22.2%). Prosthesis embolization in the ascending aorta occurred in 5.5% of patients who experienced early implant failure. All implant failure cases were managed percutaneously with gain in aortic valve area from 0.44 ± 0.17 to 1.28 ± 0.27 cm2 (P < 0.001), decrease of mean transaortic gradient from 55.00 ± 19.51 to 11.58 ± 5.91 mmHg (P < 0.001) and no MACCE at 30 days. After 11 ± 6 months, MACCE occurred cumulatively in two patients (11.1%). Conclusions : Early implant failure can complicate the TAVI procedure with the CoreValve system, but it can be managed safely and effectively with bailout transcatheter techniques, avoiding surgery, with good early and mid‐term clinical and echocardiographic results. © 2010 Wiley‐Liss, Inc. 相似文献

Aims: To define the impact of transcutaneous aortic valve implantation (TAVI) using the CoreValve prosthesis on myocardial deformation in a serial echocardiographic study with analysis of strain and strain rate. Methods: In 36 patients (83 ± 6 years; EuroScore: 26 ± 13%) with severe aortic stenosis scheduled for CoreValve implantation serial echocardiographic studies pre‐ and postintervention (within 1 month) were performed. Midparasternal short‐axis and three apical views were acquired. Using customized computer software which allows automatic frame‐by‐frame tracking of acoustic markers during the heart cycle circumferential, radial, and longitudinal strain (CS, RS, and LS) and strain rate (CSR, RSR, and LSR) were calculated for each segment in a 16 segment model of the left ventricle. Results: Longitudinal strain, systolic, and early diastolic longitudinal strain rate increased significantly within 1 month after TAVI (LS from –15.8 ± 3.6% to –17.6 ± 3.1%; P < 0.001; LSR(S) from –1.03 ± 0.21 s?1 to –1.21 ± 0.19 s?1; P < 0.001 and LSR (E) from –1.15 ± 0.42 s?1 to 1.51 ± 0.44 s?1; P < 0.001). Circumferential strain and strain rate values remained unchanged after CoreValve implantation. RS (29.1 ± 17.1 to 34.0 ± 15.8%; ns), RSR (S) (1.56 ± 0.69 to 1.91 ± 0.87 s?1; ns) and RSR(E) (–1.56 ± 0.78 to –1.81 ± 0.82 s?1; ns) increased only nonsignificantly after TAVI. Analysis of covariance showed only chronic kidney disease to have a relevant impact on early diastolic LSR (P = 0.01). Conclusions: Mainly longitudinal mechanics respond to unloading of the left ventricle after TAVI for severe aortic stenosis while radial and circumferential deformation is substantially unchanged. Pacemaker implantation or onset of left bundle brunch block after TAVI do not influence early myocardial deformation parameters. (Echocardiography 2011;28:397‐401) 相似文献

Background: The management of patients with degeneration of surgical bioprosthetic valve replacement remains a challenge because of the higher risk of re‐do aortic valve replacement. We present a case series of five patients with degenerated aortic bioprostheses treated with transfemoral transcatheter aortic valve implantation (TAVI). Methods: From December 2009 to May 2010, five patients with degenerated aortic valve bioprostheses (aortic valve area < 1 cm2 or severe aortic regurgitation), an excessive operative risk (EuroSCORE ≥ 30%), symptoms of heart failure (NYHA ≥ III) and an internal diameter of bioprosthetic aortic valve 20.5 ± 0.5 mm were included. Procedures were performed without hemodynamic support using femoral arteries. Balloon valvuloplasty with a 20‐mm balloon under rapid pacing was carried out before valve implantation. The 26‐mm CoreValve prosthesis, 18‐F‐generation (Medtronic, Minneapolis, Minnesota) was inserted retrograde under fluoroscopic guidance. Invasive and echocardiographic measurements were done immediately before and after TAVI. Clinical followup and echocardiography were performed after procedure (mean followup 72 days ± 60, range: 176–30 days). Results: In all patients TAVI was successful with immediate decrease of transaortic peak‐to‐peak pressure (P = 0.002). Mild aortic regurgitation occurred in two patients and one patient received a new permanent pacemaker. Major adverse cardiac and cerebrovascular events did not arise. NYHA functional class improved in all patients and left ventricular ejection fraction increased (P = 0.019). Conclusion: Our experiences with the valve‐in‐valve technique using the CoreValve prosthesis suggest that transfemoral TAVI is feasible in high risk patients with degenerated aortic bioprostheses. © 2010 Wiley‐Liss, Inc. 相似文献

Treatment options for re‐stenotic aortic valve prosthesis implanted by transcatheter technique have not been evaluated systematically. We describe the case of a 75‐year‐old dialysis patient who was treated by transcatheter aortic valve implantation 3.5 years ago and now presented with severe stenosis of the percutaneous heart valve. The patient was initially treated with a trans‐apical implantation of an Edwards Sapien 26 mm balloon expandable valve. The patient remained asymptomatic for 3 years when he presented with increasing shortness of breath and significant calcification of the valve prosthesis on transesophageal echocardiography. Valve‐in‐valve percutaneous heart valve implantation using a 26‐mm CoreValve prosthesis was performed under local anesthesia. The prosthesis was implanted without prior valvuloplasty. Pacing with a frequency of 140/min was applied during placement of the valve prosthesis. Positioning was done with great care using only fluoroscopic guidance with the aim to have the ventricular strut end of the CoreValve prosthesis 5 mm higher than the ventricular strut end of the Edwards Sapien prosthesis. After placement of the CoreValve prosthesis within the Edwards Sapien valve additional valvuloplasty with rapid pacing was performed in order to further expand the CoreValve prosthesis. The final result was associated with a remaining mean gradient of 5 mm Hg and no aortic regurgitation. In conclusion, implantation of a CoreValve prosthesis for treatment of a restenotic Edwards Sapien prosthesis is feasible and is associated with a good functional result. © 2012 Wiley Periodicals, Inc. 相似文献

Background: Transcatheter Aortic Valve Implantation ( TAVI) is an emerging alternative to medical therapy reserved to a limited population with severe aortic stenosis. The European consensus document recommended TAVI for prohibitive‐risk patients not eligible for conventional surgery (prohibitive risk defined as expected mortality ≥ 20% calculated with the Logistic EuroScore (LES) in association with clinical judgment). To date, there is lack of clarity on data about outcomes of TAVI in lower risk patients. We sought to evaluate the outcomes of patients undergoing TAVI with LES ≥ 20% in comparison with patients with LES < 20%. Method: Of 165 patients who underwent TAVI using the 18‐French Medtronic CoreValve (N = 153) and the Sapien Edwards? (N = 12) at our Institution between June 2007 and September 2010, we identified those with LES < 20%, with prosthesis implantation (n = 84), and reported on their clinical outcome compared with patients with LES ≥ 20% (n = 78). The primary endpoint was the incidence of overall death and major adverse cerebrovascular and cardiac events (MACCE) at 30‐day and midterm follow‐up stratifying patients by clinical characteristics. Results: At 30‐day, a significant higher incidence of MACCE (20.8% vs. 6.0%, odds ratio [OR] 4.08 95% confidence interval [CI] 1.42–11.74, P = 0.009) and death (15.6% vs. 2.4%, OR 7.45 95% CI 1.61–34.48, P = 0.010) was reported in the LES ≥ 20% group as compared with the LES < 20% group, respectively. The 12‐month MACCE rates was (27.1% vs. 11.4%, hazard ratio [HR] 2.47 95% CI 0.93–6.63, P = 0. 071) for LES ≥ 20% and LES < 20% patients, respectively (mortality rates was 25.7% vs. 6.8% HR 4.21 95% CI 1.24–14.30, P = 0.021). Conclusion: This study tends to suggest that current mortality reported after TAVI could be significantly affected by the very‐high risk profile of the population which currently undergoes this procedure, making comparison with surgical series rather unreliable. © 2011 Wiley Periodicals, Inc 相似文献

Objectives:The aim of the present analysis is to compare the quantitative angiographic aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) among three balloon-expandable valves.Background:Quantitative videodensitometric aortography is an objective, accurate, and reproducible tool for adjudication of AR following TAVI.Methods:This is a retrospective corelab analysis, independent from industry, of aortograms from patients treated with TAVI using the balloon-expandable Myval transcatheter heart valve (THV) (Meril Life Sciences Pvt. Ltd., India), Sapien 3, and XT THVs (Edwards Lifesciences, Irvine, CA, USA). The study comprised of 108 analyzable aortograms from consecutive patients in a multicenter European registry who underwent Myval THV implantation. The results of quantitative assessment of AR in the Sapien 3 THV (n = 397) and Sapien XT THV (n = 239) were retrieved from a published pooled database.Results:The Myval THV had the lowest proportion of patients with moderate or severe angiographic quantitative AR (2.8%) compared to the Sapien 3 THV (8.3%; p = 0.049) and Sapien XT THV (10.9%; p = 0.012). Furthermore, the Myval THV had the lowest mean angiographic quantitative AR (6.3 ± 6.3%), followed by Sapien 3 THV (7.6 ± 7.1%) and Sapien XT THV (8.8 ± 7.5%), and it was significantly lower than that of the Sapien XT THV (p = 0.006), but not significantly different from Sapien 3 THV (p = 0.246).Conclusion:The Myval THV, in comparison with other BEV’s analyzed in our database, showed a lower occurrence of moderate or severe AR after TAVI. These results should be confirmed in prospective cohorts of randomized patients with head-to-head THV comparisons. 相似文献

Transcatheter aortic valve implantation (TAVI) is a highly specialized technique offering a new therapeutic option to patients at high risk for conventional surgery. However, despite continuous improvements in operators' expertise and device technology, complications associated with this catheter procedure are not uncommon. We report an unusual case of late contained rupture of the aortic annulus, combining a para‐aortic false aneurysm and a ventricular septal defect, after the placement of an Edwards Sapien prosthesis. © 2012 Wiley Periodicals, Inc. 相似文献

Transcatheter aortic valve implantation (TAVI) has been developed as an alternative to conventional aortic valve replacement for the treatment of symptomatic severe aortic stenosis in high‐risk patients. Nevertheless, TAVI has been associated with serious complications such as stroke, vascular injury, renal failure, and arrhythmia. Herein we describe a case of distortion of the Edward‐Sapien prosthesis (Edwards Lifesciences, USA), which was mounted on a balloon‐expandable stent, after chest compression for cardiac resuscitation in a patient who underwent TAVI for severe aortic stenosis. © 2012 Wiley Periodicals, Inc. 相似文献

Transcatheter aortic valve implantation is an alternative to conventional aortic valve replacement for patients at high surgical risk, with favorable procedural outcomes. Aortic regurgitation remains an off‐label indication. Recent case reports describe the successful use of a second CoreValve inside a malpositioned first CoreValve. In the current case, we report for the first time a valve‐in‐valve procedure for the treatment of a severely insufficient CoreValve prosthesis using the Edwards‐Sapien prosthesis. © 2009 Wiley‐Liss, Inc. 相似文献

This report documents the first reported case of transaortic transcatheter aortic valve implantation (TAVI) using the CoreValve ReValving system (Medtronic CoreValve System, Luxembourg), within a previous bioprosthetic aortic valve replacement. TAVI has become a recognized percutaneous treatment for patients with severe native or bioprosthetic aortic valve stenosis. However, as the number of patients screened for TAVI increases, a number of patients are found with absolutely no option for peripheral arterial access, either from the femoral or subclavian routes. Transaortic CoreValve placement offers an alternate minimally invasive hybrid surgical/interventional technique when peripheral access is not possible. A CoreValve prosthesis was implanted via the transaortic route in an 81‐year‐old woman with severe bioprosthetic aortic valve stenosis (21 mm Mitroflow pericardial valve, peak instantaneous gradient of 99 mmHg, effective valve orifice area (EOA) of 0.3 cm2, as ilio‐femoral and left subclavian angiography revealed small calibre vessels (<6 mm). Access was achieved via a mini thoracotomy via the left anterior second intercostal space. The procedure went without complication. Post procedure the patient was transferred directly to the Cardiac Care Unit for recuperation. Post procedure echocardiography showed that the TAVI was well positioned with no para‐valvular leak and a reduction in peak instantaneous gradient to 30 mmHg and an increase in EOA to 1.5 cm2. She was discharged on the third post‐procedural day in sinus rhythm with a narrow QRS complex. CoreValve implantation within previous surgical bioprosthesis is now an established treatment. The transaortic approach to transcatheter implantation is a promising recent development, when due to anatomical reasons, transfemoral or subclavian TAVI is not feasible. © 2011 Wiley‐Liss, Inc. 相似文献
