Project description:Transcatheter aortic valve implantation (TAVI) has emerged as an alternative technique to treating aortic stenosis in patients with high surgical risk. We present a case of a successful transfemoral TAVI in a high-risk patient with an extremely tortuous iliofemoral system and a significant S-type bend in the descending aorta. With careful preprocedure planning and using all the techniques available, TAVI can be performed in the most challenging patients.

Project description:BackgroundTranscatheter aortic valve implantation (TAVI) might be a feasible treatment option for more patients with bicuspid aortic valve (BAV) stenosis. However, long-term follow-up data in this population are scarce.AimsThe aim of this study was to evaluate three-year outcomes after TAVI in patients with BAV.MethodsA total of 246 consecutive patients who underwent TAVI at a single centre in China between March 2013 and February 2018 were enrolled in this study. Clinical outcomes, health status and echocardiography were followed and recorded for three years.ResultsAmong 109 (44.3%) BAV patients, 61.5% were Type 0 and 36.7% were Type 1 BAV patients. BAV patients were younger (75 vs 77 years, p=0.041) and had a lower Society of Thoracic Surgeons (STS) score (5.09 vs 6.00, p=0.026) compared to tricuspid aortic valve (TAV) patients. There were no differences in three-year survival rates between bicuspid and tricuspid patients (87.1% vs 79.5%, log-rank p=0.126). Multivariate Cox regression analysis adjusting for confounding factors revealed a similar risk of all-cause mortality in the BAV population (hazard ratio [HR] 0.86, 95% confidence interval [CI]: 0.44-1.70, p=0.666). Except for the rate of permanent pacemaker implantation that was lower in BAV patients (11.9% vs 21.9%, p=0.041), the incidence of other clinical adverse events was comparable between the two groups. Both BAV and TAV patients showed an obvious improvement in valve haemodynamics, which was sustained for three years. In addition, similar left ventricular reverse remodelling was found during follow-up.ConclusionsBAV patients showed similar satisfactory three-year clinical outcomes, persistent valve haemodynamics improvement, and obvious cardiac reverse remodelling after TAVI compared to TAV patients.

Project description:BackgroundTranscatheter aortic valve replacement (TAVR) is a viable treatment option for managing aortic prosthetic valve dysfunction. Although the transfemoral approach is the most commonly used and preferred treatment strategy for TAVR, complex vascular access, such as aortic aneurysm, severe tortuosity, and shaggy aorta, is challenging.Case summaryAn 87-year-old man, who underwent surgical aortic valve replacement for aortic stenosis using a 21-mm Carpentier-Edwards Perimount Valve, presented with New York Heart Association functional Class III dyspnoea. He was diagnosed as having severe symptomatic structural valve deterioration of a bioprosthetic aortic valve. Computed tomography revealed a tortuous and shaggy descending aorta with a saccular aneurysm in the aortic arch. Simultaneous transfemoral valve-in-valve TAVR and Zone 2 thoracic endovascular aortic repair (TEVAR) with debranching were successfully performed using a 22-Fr 65-cm sheath. Although the patient developed paraplegia due to transient spinal cord ischaemia associated with TEVAR, he fully recovered with vasopressor therapy.DiscussionTo the best of our knowledge, this is the first report on simultaneous successful 'valve-in-valve' TAVR and debranching TEVAR using the transfemoral approach. This case demonstrated the feasibility of single-stage transfemoral TAVR and TEVAR in a high-risk patient with multicomponent disease.

Project description:BackgroundBicuspid aortic valve (BAV) is common congenital malformation, bicuspid aortic stenosis accounts for a substantial proportion of patients with aortic valve stenosis (AS). Bicuspid AS are more likely to have aortic dilatation with slightly less elliptical annuli, which might lead to paravalvular aortic valve regurgitation (AR) and permanent pacemaker implantation (PPM) after TAVI with higher mortality. Our study aims to understand the therapeutic efficacy and safety of transcatheter aortic valve implantation (TAVI) with a supra-annular structure-based sizing strategy in Chinese AS patients with BAV versus tricuspid aortic valve (TAV).MethodsSeventy-four consecutive tricuspid AS patients and 44 bicuspid AS patients were included and enrolled in the study for analysis. Both groups underwent TAVI performed using balloon sizing less than mild paravalvular AR to assess the proper prosthesis size. The myocardial function within 1 year postoperative were sequentially evaluated using the New York Heart Association (NYHA) class, and echocardiography measurements. The incidence rates of complications at 30 days and 1 year were analyzed. During the 1-year follow-up, the time of death from any cause or complications in both groups was recorded.ResultsThe study found that the percentage of patients with class III-IV of NYHA dropped after TAVI in both groups, and no significant difference between both groups at 1 year. Compared with the tricuspid AS group patients, Bicuspid group patients had more improvement in mean aortic valve gradient from baseline to 1year (-47.47±13.38 vs. -50.22±19.25 mmHg, P<0.05). There were no significant differences in 30-day and one-year compliance outcomes except a lower incidence of AR at post-procedure and 30 days in the tricuspid AS group as the Bicuspid AS group. There were no statistically significant differences in the time of death from any cause or significant complications between groups.ConclusionsTAVI has acceptable therapeutic efficacy and safety and is feasible for AS patients with BAV in China.

Project description:BackgroundProspective data about transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) patients are limited.AimsWe aimed to evaluate the clinical impact of the Evolut PRO and R (34 mm) self-expanding prostheses in BAV patients and explore the impact of different computed tomography (CT) sizing algorithms in a prospective registry.MethodsA total of 149 bicuspid patients were treated in 14 countries. The primary endpoint was the intended valve performance at 30 days. Secondary endpoints were 30-day and 1-year mortality, severe patient-prosthesis mismatch (PPM) and the ellipticity index at 30 days. All study endpoints were adjudicated according to Valve Academic Research Consortium 3 criteria.ResultsThe mean Society of Thoracic Surgeons score was 2.6% (1.7-4.2). Type I L-R BAV was observed in 72.5% of the patients. Evolut valve sizes 29 and 34 mm were utilised in 49.0% and 36.9% of the cases, respectively. The 30-day cardiac death rate was 2.6%; the 1-year cardiac death rate was 11.0%. Valve performance at 30 days was observed in 142/149 (95.3%) patients. The mean aortic valve area post-TAVI was 2.1 (1.8-2.6) cm2, and the mean aortic gradient was 7.2 (5.4-9.5) mmHg. No patient had more than moderate aortic regurgitation at 30 days. PPM was observed in 13/143 (9.1%) surviving patients and was severe in 2 patients (1.6%). Valve function was maintained at 1 year. The mean ellipticity index remained 1.3 (interquartile range 1.2-1.4). Overall, 30-day and 1-year clinical and echocardiography outcomes were similar between the two sizing strategies.ConclusionsBIVOLUTX demonstrated a favourable bioprosthetic valve performance and good clinical outcomes after TAVI with the Evolut platform in patients with bicuspid aortic stenosis. No impact from the sizing methodology could be identified.

Project description:The bicuspid aortic valve (BAV) represents a complex anatomic scenario for transcatheter aortic valve replacement (TAVR) because of its unique technical challenges. As TAVR is moving towards younger and lower-risk populations, the proportion of BAV patients undergoing TAVR is expected to rise. Initial experiences of TAVR with first-generation transcatheter heart valves in high surgical risk patients with BAV stenosis showed higher rates of device failure and periprocedural complications as compared to tricuspid anatomy. The subsequent advances in imaging techniques and understanding of BAV anatomy, new iterations of transcatheter heart valves, and growing operators' experience yielded better outcomes. However, in the lack of randomized trials and rigorous evidence, the field of TAVR in BAV has been driven by empirical observations, with wide variability in transcatheter heart valve sizing and implantation techniques across different centers and operators. Thus, in this review article, we provide a fully illustrated overview of operative periprocedural steps for TAVR in BAV stenosis, though recognizing that it still remains anecdotal.

Project description:ImportanceThe outcomes of transcatheter aortic valve replacement (TAVR) in low-risk patients with bicuspid aortic valve stenosis have not been studied in a large scale, multicentered, prospective fashion.ObjectiveTo evaluate the procedural safety, efficacy, and 30-day outcomes of TAVR in patients with bicuspid aortic stenosis at low surgical risk.Design, setting, and participantsThe Low Risk Bicuspid Study is a prospective, single-arm trial study with inclusion/exclusion criteria developed from the Evolut Low Risk Randomized Trial. Follow-up is planned for 10 years. Patients underwent TAVR at 25 centers in the United States who were also participating in the Evolut Low Risk Randomized Trial from December 2018 to October 2019. Eligible patients had severe bicuspid aortic valve stenosis and met American Heart Association/American College of Cardiology guideline indications for aortic valve replacement.InterventionsPatients underwent attempted implant of an Evolut or Evolut PRO transcatheter aortic valve, with valve size based on annular measurements.Main outcomes and measuresThe prespecified primary end point was the incidence of all-cause mortality or disabling stroke at 30 days. The prespecified primary efficacy end point was device success defined as the absence of procedural mortality, the correct position of 1 bioprosthetic heart valve in the proper anatomical location, and the absence of more than mild aortic regurgitation postprocedure.ResultsA total of 150 patients underwent an attempted implant. Baseline characteristics include mean age of 70.3 (5.5) years, 48.0% female (n = 72), and a mean Society of Thoracic Surgeons score of 1.4 (0.6%). Most patients (136; 90.7%) had Sievers type I valve morphology. The incidence of all-cause mortality or disabling stroke was 1.3% (95% CI, 0.3%-5.3%) at 30 days. The device success rate was 95.3% (95% CI, 90.5%-98.1%). At 30 days, the mean (SD) AV gradient was 7.6 (3.7) mm Hg and effective orifice area was 2.3 (0.7) cm2. A new permanent pacemaker was implanted in 22 patients (15.1%). No patients had greater than mild paravalvular leak.Conclusions and relevanceTranscatheter aortic valve replacement in low-surgical risk patients with bicuspid aortic valve stenosis achieved favorable 30-day results, with low rates of death and stroke and high device success rate.Trial registrationClinicalTrials.gov Identifier: NCT03635424.

Project description:This original clinical research study id focused on description of baseline anatomy and outcomes after transcatheter aortic valve implantation (TAVI) in patients presenting with severe aortic stenosis (AS) and bicuspid aortic valve (BAV). We compared this BAV population with a population of patients with AS and tricuspid aortic valves after a propensity score matching developed by a multivariate logistic regression according to a non-parsimonious approach. Baseline anatomical characteristics were obtained by transthoracic echocardiography (TTE) and multi-sliced computed tomography (MSCT) and compared by chi-square and t-student tests. Outcomes were evaluated by correct fisher test at in hospital and 30 days follow-up. We found that BAV patients presents more complicated baseline anatomy as compared to patients with tricuspid valves. These anatomical features lead to higher procedural complications as the need for a second device implantation. However this does not translate into increase in mortality rate at 30 days follow-up but rather correlate to a lower device success rate.
