Project description:BackgroundCoronary obstruction during transcatheter aortic valve replacement (TAVR) is a rare, yet life-threatening, complication. The routine use of left main (LM) protection with or without stent placement in high-risk patients remains controversial. The aim of this study was to evaluate the outcomes of LM protection during TAVR and identify anatomic factors associated with need for stent placement.MethodsWe retrospectively reviewed all TAVR cases (native and valve-in-valve) performed in our institution between 2014 and 2019 and identified patients who underwent LM protection with a coronary wire, balloon, and/or stent during the procedure. We compared the pre-TAVR computed tomography aortic root characteristics, procedural data, short-, and long-term outcomes among the patients who eventually received an LM stent and those who did not.ResultsAmong 1925 TAVR patients, 41 (2.1%) underwent LM protection, and 10 of them (25%) had eventually a stent placed in the LM for threatened obstruction after valve deployment. In the native TAVR group (n = 35), 8 patients underwent LM stenting. A larger TAVR prosthesis, larger annular circumference (83.8 vs 76.1 mm; P = .038), lower ratio of sinotubular junction diameter to prosthesis size (1.02 vs 1.11; P = .032), and longer left coronary cusp (15.1 vs 13.9 mm; P = .18) were associated with higher incidence of LM stenting. In the valve-in-valve TAVR group (n = 6), 5 patients had a valve-to-coronary distance of less than 4 mm, and 2 of them received an LM stent. Both stent and nonstent groups had excellent outcomes with no major adverse cardiovascular events or coronary obstruction at 30 days. After a median follow-up of 351 days, 4 patients died (9.7%) (1 in the stent and 3 in the nonstent group), without any cases of late coronary obstruction or percutaneous coronary intervention in either group.ConclusionsLM protection with a coronary guidewire, balloon, or stent is a safe and effective method of coronary protection during TAVR in appropriately selected high-risk patients. Annular circumference, prosthesis size, left coronary cusp length, LM ostial height, and ratio of sinotubular junction to prosthesis size are important predictors of stent deployment.

Project description:Transcatheter aortic valve replacement (TAVR) using a balloon-expandable valve is an accepted alternative to surgical replacement for severe, symptomatic aortic stenosis in high risk or inoperable patients. Intraprocedural transesophageal echocardiography (TEE) offers real-time imaging guidance throughout the procedure and allows for rapid and accurate assessment of complications and procedural results. The value of intraprocedural TEE for TAVR will likely increase in the future as this procedure is performed in lower surgical risk patients, who also have lower risk for general anesthesia, but a greater expectation of optimal results with lower morbidity and mortality. This imaging compendium from the PARTNER (Placement of Aortic Transcatheter Valves) trials is intended to be a comprehensive compilation of intraprocedural complications imaged by intraprocedural TEE and diagnostic tools to anticipate and/or prevent their occurrence.

Project description:BACKGROUND:Transaxillary access (TAx) has shown promise as an excellent alternative TAVR option, but data on the Edwards SAPIEN 3 in TAx-TAVR is limited. We sought to study the safety and efficacy of TAx-TAVR using this current-generation balloon-expandable valve. METHODS:A retrospective study of our first 24 TAx and 20 transthoracic (TT) TAVR patients treated with the SAPIEN 3 valve was performed, and the patients' preoperative characteristics, procedural outcomes, and clinical outcomes were compared to our first 100 transfemoral (TF) patients using the SAPIEN 3 device. RESULTS:There were no statistical differences observed for outcomes between the TAx and TF groups, despite the TAx patients having more comorbidities (STS-PROM 11.3?±?7.6 versus 7.3?±?5.2, p?=?0.042). In addition, no significant difference was found in the fluoroscopy time and contrast amount between the two groups. The patients' baseline characteristics were similar between the TAx and TT groups. Their procedural and clinical outcomes were comparable, but there was a trend towards lower incidence of acute kidney injury (13.0% versus 23.5%), new-onset atrial fibrillation (5.6% versus 33.3%), shorter median length of stay postoperatively (4 versus 6?days), fewer discharges to rehabilitation (16.7% versus 35.0%), and a lower rate of readmission within 30-days (8.3% versus 35.0%), all favoring TAx access. CONCLUSIONS:TAx-TAVR with the SAPIEN 3 valve is a safe alternative to TF access. It offers advantages of improved recovery over TT access, and appears to be a superior alternative-access option for TAVR. TAx access could be preferred when TF access is not feasible.

Project description:We present the case of an 82-year-old man whose left coronary ostium became obstructed 15 months after transcatheter aortic valve replacement (TAVR) with a balloon-expandable valve. The patient underwent TAVR for symptomatic severe aortic stenosis with no complications. Fifteen months after the initial TAVR, the patient complained of chest pain while exercising, and the exercise stress myocardial perfusion scintigraphy demonstrated the development of regional myocardial ischemia in the region of the left coronary artery. Coronary angiography implied severe stenosis in the ostium of the left coronary artery. Computed tomography angiography and intravascular ultrasonography indicated a soft tissue component along with stent struts, which was considered to cause delayed coronary obstruction. Our report emphasizes the importance of having a low threshold for clinically suspecting delayed coronary obstruction in patients who have undergone TAVR, even after several years of the procedure. <Learning objective:Delayed coronary obstruction (DCO) should be suspected in patients presenting with new ischemic symptoms after transcatheter aortic valve replacement (TAVR). DCO may occur even in the case of TAVR with a balloon-expandable prosthetic valve, on antithrombotic regimens, and several years after the initial procedure.>.

Project description:Transcatheter aortic valve replacement (TAVR) has emerged as a life-saving and effective alternative to surgical valve replacement in high-risk, elderly patients with severe calcific aortic stenosis. Despite its early promise, certain limitations and adverse events, such as suboptimal placement and valve migration, have been reported. In the present study, it was aimed to evaluate the effect of various TAVR deployment locations on the procedural outcome by assessing the risk for valve migration. The deployment of a balloon-expandable Edwards SAPIEN valve was simulated via finite element analysis in a patient-specific calcified aortic root, which was reconstructed from CT scans of a retrospective case of valve migration. The deployment location was parametrized in three configurations and the anchorage was quantitatively assessed based on the contact between the stent and the native valve during the deployment and recoil phases. The proximal deployment led to lower contact area between the native leaflets and the stent which poses higher risk for valve migration. The distal and midway positions resulted in comparable outcomes, with the former providing a slightly better anchorage. The approach presented might be used as a predictive tool for procedural planning in order to prevent prosthesis migration and achieve better clinical outcomes.

Project description:Background The incidence of conduction abnormalities requiring permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR) with early and later generation prostheses remains debated. Methods and Results Based on the administrative hospital-discharge database, we collected information for all patients treated with TAVR between 2010 and 2019 in France. We compared the incidence of PPI after TAVR according to the type and generation of valve implanted. A total of 49 201 patients with aortic stenosis treated with TAVR using the balloon-expandable (BE) Edwards SAPIEN valve (early Sapien XT and latest Sapien 3) or the self-expanding (SE) Medtronic CoreValve (early CoreValve and latest Evolut R) were found in the database. Mean (SD) follow-up was 1.2 (1.5 years) (median [interquartile range] 0.6 [0.1-2.0] years). PPI after the procedure was reported in 13 289 patients, among whom 11 010 (22.4%) had implantation during the first 30 days. In multivariable analysis, using early BE TAVR as reference, adjusted odds ratio (95% CI) for PPI during the first 30 days was 0.88 (0.81-0.95) for latest BE TAVR, 1.40 (1.27-1.55) for early SE TAVR, and 1.17 (1.07-1.27) for latest SE TAVR. Compared with early BE TAVR, the adjusted hazard ratio for PPI during the whole follow-up was 1.01 (0.95-1.08) for latest BE TAVR, 1.30 (1.21-1.40) for early SE TAVR, and 1.25 (1.18-1.34) for latest SE TAVR. Conclusions In patients with aortic stenosis treated with TAVR, our systematic analysis at a nationwide level found higher rates of PPI than previously reported. BE technology was independently associated with lower incidence rates of PPI both at the acute and chronic phases than SE technology. Recent generations of TAVR were not independently associated with different rates of PPI than early generations during the overall follow-up.

Project description:Background and objectivesTranscatheter aortic valve replacement (TAVR) has been reported as a good alternative for surgical aortic valve replacement in patients with small aortic annulus. Head-to-head comparisons of different transcatheter aortic valves in these patients are insufficient. We compared the outcomes after TAVR between two different types of recent transcatheter aortic valves (self-expanding vs. balloon-expandable) in patients with small aortic annulus.MethodsA total of 70 patients with severe aortic stenosis and small annulus (mean diameter ≤23 mm or minimal diameter ≤21 mm on computed tomography) underwent TAVR with either a self-expanding valve with supra-annular location (n=45) or a balloon-expandable valve with intra-annular location (n=25). The echocardiographic hemodynamic parameters after TAVR and 1-year follow-up were compared.ResultsBetween the self-expanding and balloon-expandable valve-treated patients, the clinical outcomes including permanent pacemaker implantation (11.1% vs. 8.0%), acute kidney injury stage 2 or 3 (4.4% vs. 4.0%), and major vascular complication (4.4% vs. 0.0%) were similar without all-cause mortality, stroke, and life-threatening bleeding during 30-day follow-up. Compared with the balloon-expandable valve-treated patients, the self-expanding valve-treated patients presented larger effective orifice area (EOA) (1.46±0.28 vs. 1.75±0.42 cm², p=0.002) and indexed EOA (0.95±0.21 vs. 1.18±0.28 cm²/m², p=0.001), whereas mean aortic valve gradient (11.7±2.9 vs. 8.9±5.2 mmHg, P=0.005) and incidence of ≥moderate prosthesis-patient mismatch (36.0% vs. 8.9%, p=0.009) were lower. These hemodynamic differences were maintained at 1-year follow-up.ConclusionsTAVR with self-expanding valves was associated with superior hemodynamic outcomes compared with balloon-expandable valves in patients with small aortic annulus.

Project description:Background:Transcatheter aortic valve replacement (TAVR) is a reliable method of treating patients with severe aortic stenosis, but is associated with postprocedure conduction defects. Objective:The purpose of this study was to compare clinical outcomes in patients who developed advanced conduction defects post-TAVR to those who did not. Methods:We conducted a retrospective chart review of 243 patients who underwent balloon-expandable TAVR with the Edwards Sapien valve to determine the incidence of advanced conduction defects in our cohort. We compared clinical outcomes including overall mortality, improvement in symptomatology, and improvement in left ventricular ejection fraction. Results:Among the 243 patients included in the study, 9.1% (22/243) required permanent pacemaker (PPM); 19.8% (48/243) developed left bundle branch block (LBBB), and 71.2% (173/243) did not develop any permanent advanced conduction defects. Overall 1-year mortality was similar across all three groups. There was significant improvement in New York Heart Association functional capacity of all groups post-TAVR, but this was much less in the PPM group (45.5% vs 68.8%, P = .04). Postprocedure from TAVR, patients with LBBB or PM were less likely to have improvement in their ejection fraction (net loss of -0.7% for LBBB and -5.7% for PPM compared to a net gain of 2.3% for no-LBBB/PM (P = .02). Conclusion:Patients who develop LBBB or require PM post-TAVR with Edwards Sapien valves are less likely to improve New York Heart Association functional capacity and more likely to have no improvement or deterioration of their pre-TAVR left ventricular ejection fraction.
