Introduction. Procedural cooperation between cardiac surgeon and interventional cardiologist to facilitate interventions such as device delivery or angioplasty (hybrid procedure) has become increasingly common in the management of patients with congenital heart disease. Design. Data were prospectively collected using a multicenter registry (C3PO). Between February 2007 and December 2008, seven institutions submitted data regarding 7019 cardiac catheterization procedures. Procedural data and adverse events (AEs) of 128 hybrid procedures were evaluated. Results. There was significant variability in the number of hybrid procedures per center, ranging from one to 89 with a median of eight. A total of 60% of interventional (vs. strictly diagnostic) hybrid procedures were performed by one center. The median weight was 3.7 kg (0.7–86 kg). Single-ventricle circulation was present in 60% of the procedures. Hybrid procedures included: patent ductus arteriosus (PDA) stent placement (n = 55), vascular rehabilitation (n = 25), ventricular septal defect (VSD) device closure (n = 7), valvotomy (n = 3), and diagnostic hybrid procedures (n = 38). Sixteen AEs occurred in 15/128 (12%) procedures. These included minor or trivial AEs (n = 9), moderate AEs (n = 5), major AEs (n = 1), and catastrophic AEs (n = 1). The type of AE documented included arrhythmias (n = 6), hypoxia or hypotension (n = 3), vessel or cardiac trauma (n = 2), and other events (n = 5). Of documented AEs, 9/16 (56%) were classified as not preventable, 6/16 (38%) as possibly preventable, and 1/16 (6%) as preventable. The incidence of AE related to PDA stent placement with surgical exposure (5/50, 10%) was significantly lower when compared with PDA stent placement performed percutaneously (4/5, 80%, P= .002). Conclusion. Hybrid procedures appear to have a low incidence of associated major AEs. PDA stent placement performed as a palliation of hypoplastic left heart syndrome (HLHS) or complex single/two ventricle patients may have a lower incidence of AEs if performed using a direct approach with surgical exposure rather than a percutaneous approach. Accurate definitions of these innovative procedures are required to facilitate prospective data collection. 相似文献

Objectives
This study sought to describe the current practices and compare outcomes according to the use of balloon aortic valvuloplasty (BAV) or not during transcatheter aortic valve replacement (TAVR).Background
Since its development, aortic valve pre-dilatation has been an essential step of TAVR procedures. However, the feasibility of TAVR without systematic BAV has been described.Methods
TAVR performed in 48 centers across France between January 2013 and December 2015 were prospectively included in the FRANCE TAVI (Registry of Aortic Valve Bioprostheses Established by Catheter) registry. We compared outcomes according to BAV during the TAVR procedure.Results
A total of 5,784 patients have been included in our analysis, corresponding to 2,579 (44.6%) with BAV avoidance and 3,205 (55.4%) patients with BAV performed. We observed a progressive decline in the use of BAV over time (78% of procedures in 2013 and 49% in the last trimester of 2015). Avoidance of BAV was associated with similar device implantation success (97.3% vs. 97.6%; p = 0.40). TAVR procedures without BAV were quicker (fluoroscopy 17.2 ± 9.1 vs. 18.5 ± 8.8 min; p < 0.01) and used lower amounts of contrast (131.5 ± 61.6 vs. 141.6 ± 61.5; p < 0.01) and radiation (608.9 ± 576.3 vs. 667.0 ± 631.3; p < 0.01). The rates of moderate to severe aortic regurgitation were lower with avoidance of BAV (8.3% vs. 12.2%; p < 0.01) and tamponade rates (1.5% vs. 2.3%; p = 0.04).Conclusions
We confirmed that TAVR without BAV is frequently performed in France with good procedural results. This procedure is associated with procedural simplification and lower rates of residual aortic regurgitation. 相似文献5.

Introduction: Although angiographic measures of restenosis, including late lumen loss, binary angiographic restenosis, and follow-up percent diameter stenosis have value in determining the efficacy of new drug - eluting stents (DES) designs, their ability to predict clinical events, including death, myocardial infarction, and target lesion revascularization (TLR) has been questioned.
Methods: We reviewed the available literature and recent DES clinical trials to determine the relationship between clinical and angiographic markers of restenosis and late clinical outcomes after stent use.
Results: Angiographic markers are useful surrogates for predicting differences in TLR between bare metal and DES. Due to the curvilinear relationship between late lumen loss and TLR and the skewedness of the late lumen loss distribution, late lumen loss as a single index has been less effective at predicting clinical differences between different DES when the absolute values of late lumen loss are low. Beyond predicting clinical restenosis, follow-up angiographic indices have been less predictive of other late clinical events, such as very late stent thrombosis or aneurysm formation.
Conclusions: Angiographic markers of restenosis may be a useful surrogate for TLR in pilot studies of patients treated with DES, but their use as a surrogate marker for all clinical events after stent placement, including death, myocardial infarction, and stent thrombosis, may be confounded by the progression of atherosclerosis at remote sites and vagaries of the distribution of late lumen loss in patients treated with DES. 相似文献

The field of interventional cardiology has significantly evolved over 40 years by overcoming several challenges. The introduction of first-generation drug-eluting stents significantly reduced the rates of restenosis, but at the expense of an increase of late stent thrombosis. Prolonged antithrombotic therapy reduced rates of stent thrombosis, but at the cost of increased bleeding. Although the advent of second-generation drug-eluting stents subsequently reduced the incidence of late stent thrombosis, its permanent nature prevents full recovery of vascular structure and function with accordant risk of very late stent failure. In the present era of interventional cardiology, the tradeoff between stent thrombosis, restenosis, and bleeding presents as a particularly complex challenge. In this review, the authors highlight major contributors of late/very late stent thrombosis while targeting stent restenosis, and they discuss evolutionary advances in stent technology and antiplatelet therapy, to further improve upon the care of patients with coronary artery disease. 相似文献

Background
The clinical outcomes of noncompaction cardiomyopathy (NCCM) range from asymptomatic to heart failure, arrhythmias, and sudden cardiac death. Genetics play an important role in NCCM.Objectives
This study investigated the correlations among genetics, clinical features, and outcomes in adults and children diagnosed with NCCM.Methods
A retrospective multicenter study from 4 cardiogenetic centers in the Netherlands classified 327 unrelated NCCM patients into 3 categories: 1) genetic, with a mutation in 32% (81 adults; 23 children) of patients; 2) probably genetic, familial cardiomyopathy without a mutation in 16% (45 adults; 8 children) of patients; or 3) sporadic, no family history, without mutation in 52% (149 adults; 21 children) of patients. Clinical features and major adverse cardiac events (MACE) during follow-up were compared across the children and adults.Results
MYH7, MYBPC3, and TTN mutations were the most common mutations (71%) found in genetic NCCM. The risk of having reduced left ventricular (LV) systolic dysfunction was higher for genetic patients compared with the probably genetic and sporadic cases (p = 0.024), with the highest risk in patients with multiple mutations and TTN mutations. Mutations were more frequent in children (p = 0.04) and were associated with MACE (p = 0.025). Adults were more likely to have sporadic NCCM. High risk for cardiac events in children and adults was related to LV systolic dysfunction in mutation carriers, but not in sporadic cases. Patients with MYH7 mutations had low risk for MACE (p = 0.03).Conclusions
NCCM is a heterogeneous condition, and genetic stratification has a role in clinical care. Distinguishing genetic from nongenetic NCCM complements prediction of outcome and may lead to management and follow-up tailored to genetic status. 相似文献9.

Interest in tricuspid valve pathology has rapidly expanded in response to reported poor clinical outcome for functional tricuspid regurgitation and the limited indications and options for treatment. In the past few years, different transcatheter technologies have emerged as alternatives to conventional surgery to serve this untreated high-risk population. In this review, the authors explore the indications for intervention in tricuspid regurgitation according to current guidelines, the published research to support the expansion of these indications including the role of transcatheter interventions, and the risk factors for therapy failure, which may help define the appropriate patient population for treatment. 相似文献

Objectives
The aim of this study was to evaluate incidence, care patterns, and clinical outcomes in patients developing new-onset atrial fibrillation (AF) following transcatheter aortic valve replacement (TAVR).Background
Pre-procedural AF has been associated with adverse outcomes in patients undergoing TAVR, but the incidence of new-onset AF, associated anticoagulant management, and subsequent clinical outcomes are unclear.Methods
Using the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry linked with Medicare claims, patients undergoing TAVR from 2011 to 2015 who developed post-procedural AF were evaluated. Patients with known AF prior to TAVR were excluded. Outcomes of interest included in-hospital mortality and stroke and all-cause mortality, stroke, and bleeding at 12 months. Multivariate adjustment was then performed to determine differences in 1-year outcomes among those with and without new post-procedural AF, stratified by anticoagulation status.Results
We identified 1,138 of 13,556 patients (8.4%) who developed new onset AF (4.4% of transfemoral [TF]–access patients, 16.5% of non-TF-access patients). Patients developing AF were older, more likely female, had higher Society of Thoracic Surgeons risk scores, and were often treated using non-TF access. Despite having a median CHA2DS2-VASc score of 5 (25th and 75th percentile: 5 to 6), only 28.9% of patients with new AF were discharged on oral anticoagulation. In-hospital mortality (7.8% vs. 3.4%; p < 0.01) and stroke (4.7% vs. 2.0%; p < 0.01) were higher among patients who developed post-procedural AF compared with those who did not. At 1 year, rates of death (adjusted hazard ratio [HR]: 1.37; 95% confidence interval [CI]: 1.19 to 1.59), stroke (adjusted HR: 1.50; 95% CI: 1.14 to 1.98), and bleeding (adjusted HR: 1.24; 95% CI: 1.10 to 1.40) were higher among patients with new-onset AF. One-year mortality rates were highest among patients who developed new-onset AF but were not discharged on anticoagulation.Conclusions
Post-TAVR AF occurred in 8.4% of patients (4.4% with TF access, 16.5% with non-TF access), with fewer than one-third of patients receiving anticoagulation at discharge, and was associated with increased risk for in-hospital and 1-year mortality and stroke. Given the clinical significance of post-TAVR AF, additional studies are necessary to delineate the optimal management strategy in this high-risk population. 相似文献15.

Objectives
The aim of this study was to characterize post-procedural intravascular ultrasound (IVUS) findings in the ABSORB Japan trial, specifically stratified by the size of target coronary arteries.Background
Despite overall noninferiority confirmed in recent randomized trials comparing bioresorbable vascular scaffolds (BVS) (Absorb BVS) and cobalt-chromium everolimus-eluting metallic stents (CoCr-EES), higher event rates of Absorb BVS have been reported with suboptimal deployment, especially in small coronary arteries.Methods
In the ABSORB Japan trial, 150 patients (2:1 randomization) were scheduled in the IVUS cohort. Small vessel was defined as mean reference lumen diameter <2.75 mm. Tapered-vessel lesions were defined as tapering index (proximal/distal reference lumen diameter) ≥1.2.Results
Overall, IVUS revealed that the Absorb BVS arm had smaller device expansion than the CoCr-EES arm did, which was particularly prominent in small- and tapered-vessel lesions. Higher tapering index was also associated with higher rates of incomplete strut apposition in Absorb BVS, but not in CoCr-EES. With respect to procedural techniques, small-vessel lesions were treated more frequently with noncompliant balloons at post-dilatation but using significantly lower pressure in the Absorb BVS arm. In contrast, tapered-vessel lesions were post-dilated at equivalent pressure but with significantly smaller balloon catheters in the Absorb BVS arm, compared with the CoCr-EES arm.Conclusions
The significantly smaller device expansion especially in small vessels may account for the poorer outcomes of Absorb BVS in this lesion type. Appropriate optimization strategy, possibly different between polymeric and metallic devices, needs to be established for bioresorbable scaffold technology.
