Transcatheter aortic valve implantation (TAVI) is associated with a risk of coronary obstruction. This complication is potentially lethal when the origin of the coronary arteries is anomalous. We describe two cases of TAVI with the SAPIEN XT (Edwards Lifesciences) and CoreValve devices (Medtronic) in patients with a single coronary artery. The tools and techniques used to anticipate the risk of acute coronary occlusion are discussed. 相似文献

We describe the first case of implantation of a transcatheter aortic valve implantation (TAVI) in a patient with an anomalous origin of the right coronary artery, coursing in between the aorta and pulmonary truncus to the right. After assessment of the risk of compression of the anomalous origin of the right coronary artery from the left coronary sinus (ARCA), the procedure was performed without complication. A brief discussion of the pathophysiology of ARCA is provided and the implications for TAVI as well as our recommendations are offered. 相似文献

Transcatheter aortic valve implantation (TAVI) for failed surgical bioprostheses, or “valve‐in‐valve” implantation, is a therapeutic option for high‐risk patients. While coronary occlusion during TAVI for native aortic stenosis has been described, in the setting of valve‐in‐valve implantation the bioprsthetic posts may be protective against this complication. We describe the first two cases of coronary occlusion following valve‐in‐valve therapy, both occurring during treatment of degenerated Mitroflow bioprostheses. Aortic root anatomy, coronary ostial position, and the specifics of the bioprosthetic valve type need to be considered in assessing and preventing this rare complication. © 2011 Wiley‐Liss, Inc. 相似文献

Transcatheter aortic valve implantation (TAVI) has nowadays replaced open heart surgery as an alternative therapeutic tool in selected patients. Thirty‐five percent of patients with severe degenerative aortic valve stenosis (AS) remain untreated because of the existing comorbidities that increase their perioperative risk. TAVI is a relatively new technique that has “come to stay” in the everyday clinical practice considering, that is the only alternative to surgery and appears to have excellent long term results. Herein, we describe a vascular complication immediately after the implantation of the Edwards SAPIEN (Edwards Lifesciences, Irvine, CA) prosthesis, followed by ad hoc percutaneous coronary intervention. © 2010 Wiley‐Liss, Inc. 相似文献

Valve‐in‐valve transcatheter aortic valve implantation (ViV‐TAVI) is an established therapy for a degenerated surgical bioprosthesis. TAVI‐in‐TAVI following ViV‐TAVI has not been previously performed. We report a high‐risk patient presenting with severe left ventricular failure secondary to undiagnosed critical aortic stenosis due to degeneration of the implanted transcatheter heart valve more than a decade after initial ViV‐TAVI for a failing stentless aortic valve homograft. Successful TAVI‐in‐TAVI reversed the clinical and echocardiographic changes of decompensated heart failure with no evidence of coronary obstruction. 相似文献

Mechanical circulatory support with impella to facilitate percutaneous coronary intervention for post‐TAVI bilateral coronary obstruction 下载免费PDF全文

One of the potential complications of transcatheter aortic valve implantation (TAVI) is coronary obstruction (CO), which can occur by displacement of heavily calcified native valve cusps against the coronary ostium. Treatment mandates immediate percutaneous coronary intervention (PCI) to restore coronary flow and improve hemodynamics and if unsuccessful, urgent implementation of circulatory support, commonly extracorporeal, with subsequent surgical revascularization. We report a case of post‐TAVI CO for which successful emergent deployment of Impella percutaneous mechanical circulatory support to restore hemodynamic stability facilitated definitive treatment with bilateral PCI. Impella support represents an expeditious, effective, and widely available therapy to complement and facilitate PCI in the treatment of CO complicating TAVI, and may diminish requirement for urgent coronary artery bypass surgery. © 2015 Wiley Periodicals, Inc. 相似文献

Successful treatment of aortic root rupture following transcatheter aortic valve implantation in a heavily calcified aorta: A novel approach to a serious complication 下载免费PDF全文

Aortic root rupture during transcatheter aortic valve implantation (TAVI) is an uncommon but almost uniformly fatal complication. We describe a novel surgical management of this complication using a combination of pledgeted sutures and prolonged direct digital compression with biomatrix and lattice adjuncts. Furthermore, our patient underwent percutaneous coronary intervention with endothelial progenitor cell‐capturing stents, which facilitated TAVI to be performed off clopidogrel therapy. We believe the use of these stents reduced the severity of hemorrhage following aortic root rupture and helped maintain vessel patency following prolonged hypotension. © 2012 Wiley Periodicals, Inc. 相似文献

Transcatheter aortic valve implantation (TAVI) is a highly effective procedure for selected patients who are at high risk for aortic valve replacement; however, the incidence of severe complications is still relevant. Coronary occlusion during TAVI is a life‐threatening complication that requires immediate diagnosis and treatment. We report the case of an 87‐years‐old woman affected by severe aortic stenosis, symptomatic for refractory heart failure, who underwent urgent balloon aortic valvuloplasty and subsequent elective transapical aortic valve implantation. Valve deployment was complicated by cardiac arrest and hemodynamic collapse, and left main coronary artery occlusion was recognized and successfully recovered by balloon angioplasty and stent implantation. Patient is alive and well 6 months after procedure. © 2011 Wiley‐Liss, Inc. 相似文献

Background
Transcatheter aortic valve implantation (TAVI) was established as an important alternative for high-risk patients with severe aortic stenosis. However, there are few data in the literature regarding coronary obstruction, that although rare, is a potentially fatal complication.Objective
Evaluate this complication in Brazil.Methods
We evaluated all patients presenting coronary obstruction from the Brazilian Registry of TAVI. Main baseline and procedural characteristics, management of the complication, and clinical outcomes were collected from all patients.Results
From 418 consecutive TAVI procedures, coronary obstruction occurred in 3 cases (incidence of 0.72%). All patients were women, without prior coronary artery bypass grafting (CABG), and with mean age of 85 ± 3 years, logistic EuroSCORE of 15 ± 6% and STS-PROM score of 9 ± 4%. All of the cases were performed with balloon-expandable Sapien XT prosthesis. In one patient, with pre-procedural computed tomography data, coronary arteries presented a low height and a narrow sinus of Valsalva. All patients presented with clinically significant severe maintained hypotension, immediately after valve implantation, and even though coronary angioplasty with stent implantation was successfully performed in all cases, patients died during hospitalization, being two periprocedurally.Conclusion
Coronary obstruction following TAVI is a rare but potentially fatal complication, being more frequent in women and with the balloon-expandable prosthesis. Anatomical factors might be related with its increased occurrence, highlighting the importance of a good pre-procedural evaluation of the patients in order to avoid this severe complication. 相似文献10.

Coronary obstruction during transcatheter aortic valve implantation is a potentially life‐threatening complication. Most of the widely used transcatheter heart valves require a certain distance between the basal aortic annular plane and the origins of the coronary arteries. We report the case of a successful valve‐in‐valve procedure with an Edwards SAPIEN XT valve into a JenaValve as a bail‐out procedure in a patient with a low originating left coronary artery and a heavily calcified aorta. © 2015 Wiley Periodicals, Inc. 相似文献

Background
Transcatheter aortic valve implantation (TAVI) has been developed recently for patients with high morbidities and who are believed to be not tolerate standard surgical aortic valve replacement. Nevertheless, the TAVI is associated with complications such as potential obstruction of coronary ostia, mitral valve insufficiency, and stent migration although it seems promising. Impairment of the coronary blood flow after TAVI is catastrophic and it was believed to be associated with the close position of the coronary orifice and the aortic leaflets and valve stent. However, few data was available as to the anatomic relationship between valve stent and aortic root anatomic structures including the coronary arterial ostia, aortic leaflets.Methods
The aortic roots were observed in 40 hearts specimens. The width of aortic leaflet, height of aortic sinus annulus to the sinutubular junction (STJ), distance between aortic sinus annulus to its corresponding coronary ostia, and coronary arterial ostia to its corresponding STJ level were measured. Moreover, the relationships of valve stent, aortic leaflets and coronary ostia before/post stent implantation and after the open of aorta were evaluated respectively.Results
Approximate three quarters of the coronary ostia were located below the STJ level. The mean distances from left, right and posterior aortic sinus annulus to the related STJ level was comparable, which was 18.5±2.7, 18.9±2.6, 18.7±2.6 mm, respectively. Meanwhile, the height of left and right aortic sinus annulus to its corresponding coronary ostia was 16.6±2.8 and 17.2±3.1 mm for left and right side respectively.Conclusions
Most of the coronary ostia were located below the STJ level and could be covered by the leaflets. This highlights the need of modified stents to prevent occlusion of coronary flow after TAVI. 相似文献12.

Transcatheter aortic valve implantation (TAVI) has become a well-established treatment option for elderly patients with symptomatic severe aortic stenosis. Coronary artery anomalies are an infrequent finding and there have only been few anecdotal reports of patients with coronary anomalies treated with TAVI. We here present a comprehensive overview of existing reports in addition to an own case series to facilitate better understanding of this potentially challenging clinical scenario. 相似文献

Transcatheter aortic valve implantation (TAVI) has emerged as a less invasive and potentially high efficacious procedure for the treatment of high‐risk patients with symptomatic aortic stenosis. Appropriate patient selection for TAVI is a key component to ultimate clinical success. Herein, we describe a patient with left ventricular outflow tract (LVOT) obstruction that became apparent only following relief of aortic stenosis with TAVI. This report highlights the dynamic nature of LVOT obstruction, which was successfully treated in our patient with catheter‐based alcohol septal ablation. The potential to unmask dynamic LVOT obstruction with TAVI should be an important consideration in patient selection for the procedure, and the postoperative assessment of these patients. © 2012 Wiley Periodicals, Inc. 相似文献

In inoperable or high-risk patients with severe aortic stenosis, transcatheter aortic valve implantation (TAVI) provides an efficacious and safe alternative to surgical aortic valve replacement. In this case report, TAVI resulted in aortic valve cusp shearing and migration into the left main coronary artery, resulting in occlusion of coronary blood flow and cardiac arrest. The patient underwent immediate cardiopulmonary support and surgical intervention with a favourable outcome. With this case report, we illustrate the etiology and management of this complication, which can be recognized nonsurgically only if a high index of suspicion exists. 相似文献

Transcatheter aortic valve implantation (TAVI) is commonly associated with some degree of aortic regurgitation (AR) secondary to the presence of paravalvular leaks. We present the case of an 86‐year‐old woman diagnosed with severe aortic stenosis who underwent TAVI with a 23‐mm Edwards‐SAPIEN valve. The procedure complicated with a severe paravalvular leak following TAVI that was unresponsive to balloon postdilation. This complication was successfully managed with the implantation of a second valve of the same diameter within the first one (“valve‐in‐valve”) resulting in trivial residual AR and the absence of significant transvalvular gradient at the end of the procedure. © 2009 Wiley‐Liss, Inc. 相似文献

Transcatheter valve‐in‐valve implantation is an emerging treatment option for high‐risk patients with failing aortic bioprostheses. The presence of the prosthesis stents is thought to prevent coronary artery obstruction, a known complication of transcatheter aortic valve implantation in the native aortic valve. The Sorin Mitroflow aortic bioprosthesis (Sorin Group, Saluggia, Italy) has a particular design in that the pericardial leaflets are mounted outside the valve stent. As a consequence, the pericardial leaflets of this prosthesis may be displaced well away from the stents during the deployment of transcatheter valves. This might explain why both the cases of coronary occlusion following valve‐in‐valve implantation reported to date occurred in patients with a malfunctioning Mitroflow bioprosthesis. We describe a patient with a malfunctioning 25 mm Mitroflow bioprosthesis successfully treated by percutaneous transcatheter valve‐in‐valve implantation, and discuss the role that balloon aortic valvuloplasty plays in the performance of this delicate procedure. © 2012 Wiley Periodicals, Inc. 相似文献

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is a rare but potentially lethal complication. Main mechanisms are sinus insufficiency or sinus sequestration with well-described risk factors. We present two cases of acute right coronary artery occlusion during TAVI with a self-expanding valve in the absence of classical risk factors and propose a novel mechanism. 相似文献

Coronary artery disease (CAD) is a frequent finding in patients with aortic stenosis (AS). Concomitant coronary artery bypass and aortic valve replacement is considered the gold standard treatment in surgical candidates. However, limited evidence is available regarding the role of coronary revascularization in patients undergoing transcatheter aortic valve implantation (TAVI). How to evaluate CAD severity in patients with AS, whether percutaneous coronary intervention (PCI) needs to be performed and what is the timing for revascularization to minimize procedural risks, remains matters of debate. The aim of this review is to summarize epidemiology, diagnostic tools and possible options for CAD management in patients undergoing TAVI with specific focus on the pros and the cons of the different timing of PCI. 相似文献

We describe the case of an 89-year-old woman who developed severe left main coronary artery stenosis shortly after transcatheter aortic valve implantation (TAVI) with the Medtronic CoreValve Revalving System. Urgent coronary angiography revealed the protrusion of a large calcium nodule of the native valve as the cause of left main narrowing, which was treated with bare-metal stent implantation. Angiographic and intravascular ultrasound findings at follow-up are reported. This case describes one of the mechanisms of a dreadful complication of TAVI and its difficult management. 相似文献

Transcatheter aortic valve implantation (TAVI) has now become an acceptable alternative to surgical aortic valve replacement for patients with severe aortic stenosis at high risk. The early enthusiasm for this technology has not diminished but rather has developed at an unprecedented rate over the last decade. Alongside the developments in implantation technique, transcatheter design, and postprocedural care, cardiac imaging modalities have also had to concurrently evolve to meet the perpetual demand for lower peri‐ and postprocedural complication rates. Although transthoracic and transesophageal echocardiography remain vital in patient's selection and periprocedural guidance, there is now emerging evidence that indicates that multidetector‐computed tomography (MDCT) may also have an equally important role to play. The aim of the current review is to examine the modern role of MDCT in assessing patients with aortic stenosis being considered for TAVI. © 2012 Wiley Periodicals, Inc. 相似文献
