Project description:BackgroundThe presence of severe aortic stenosis in quadricuspid aortic valve (QAV) is an extremely rare combination, and it is unknown whether transcatheter aortic valve replacement (TAVR) is a safe option due to the low incidence.Case summaryWe present two patients diagnosed with severe aortic stenosis with QAV morphology type 1 (Nakamura classification). All patients presented to our hospital for evaluation because of worsening functional class, dyspnoea, or syncope. During tomographic planning, the aortic annulus was measured at the level of the deepest sinus for the selection of the number of devices. Due to the presence of four cusps, the smallest cusp was excluded, and three sinuses were virtualized for placement of the pigtail catheter during the procedure. Without complications, a 23 mm Edwards SAPIEN 3 was deployed through the femoral artery in both patients. Control aortography showed no valve leakage or regurgitation.DiscussionIn patients with QAV and aortic stenosis undergoing TAVR, similar to the tricuspid valve, tomographic planning can be used to ensure the success of the procedure. However, unlike the tricuspid valve, where the selection of the device number is based on the measurements of the aortic annulus at the level of the non-coronary sinus, in these QAV cases, we perform the measurements at the level of the deepest aortic sinus (right coronary sinus).

Project description:Coronary artery obstruction is an uncommon yet devastating complication of transcatheter aortic valve replacement (TAVR) and may necessitate leaflet modification. A 38-year-old man presented to our center with quadricuspid aortic valve with severe aortic regurgitation. Double leaflet modification was performed with the Bioprosthetic or native Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA) technique prior to TAVR, creating 6 leaflets from 4. The patient tolerated the procedure well with symptomatic improvement. Follow-up transthoracic echocardiogram showed normal bioprosthetic aortic valve function. This case demonstrates feasibility of this procedure with comprehensive preprocedural analysis and intraprocedural imaging guidance.

Project description:BackgroundQuadricuspid aortic valve (QAV) is a rare congenital malformation that can present with aortic regurgitation or aortic stenosis (AS)), requiring surgical treatment. Transcatheter aortic valve replacement (TAVR) is an alternative treatment for older patients and its prognosis for QAV therapy remains challenging. We sought to examine our early experience with TAVR in patients with QAV.Materials and methodsProspectively collected data were retrospectively reviewed in patients with QAV undergoing TAVR in our institution.ResultsFive patients with QAV and AR or AS were treated with TAVR between January 2016 and January 2022. The mean age was 73.8 years (range 69-82 years), and the median Society of Thoracic Surgeons score was 7.51% (range 2.668-18.138%). Two patients had type B and three had either type A, D, or F according to the Hurwitz and Roberts classification for QAV. Four patients with pure aortic regurgitation underwent transapical TAVR using the J-Valve system, and the patient with severe AS underwent transfemoral TAVR using the Venus-A system. Procedural success was achieved in all five patients. Trivial paravalvular leak was only detected in one case after the procedure, and one patient received a permanent pacemaker due to high-degree atrioventricular block three days later. The median follow-up period was 18 (12-56) months. After discharge, no deaths occurred during the 1 year follow-up. All patients improved by ≥1 New York Heart Association functional class at 30 days; four patients were in functional class ≤II later in the follow-up period. All patients' heart failure symptoms improved considerably.ConclusionOur early experience with TAVR in QAV demonstrates these procedures to be feasible with acceptable early results. Further follow-up is necessary to determine the long-term outcomes of this modality.Clinical trial registration[ClinicalTrials.gov], identifier [NCT02917980].

Project description:Background: Quadricuspid aortic valve (QAV) is a rare congenital cardiac anomaly associated with symptomatic aortic regurgitation (AR) or aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) for QAV remains uncertain. Methods: We retrospectively reviewed prospectively collected data from patients with QAV undergoing TAVR in our center and conducted a systematic literature review for further investigation. Results: Five patients with QAV were treated with TAVR between April 2016 and December 2023. The median age was 67 years (range: 59-86), and the median Society of Thoracic Surgeons score (STS-score) was 3.750% (range: 0.916%-11.823%). Procedural success was achieved in all cases. The median follow-up period was 3 years (from 30 days to 7 years). Four of the patients exhibited no serious complications, while one experienced delayed coronary obstruction. Our systematic review included 31 cases from 21 publications and our center. The median age of patients was 79 years (range: 57-90), including 18 males. The median STS score was 7.835%. Severe AS was present in 64.5% of the patients and severe AR in 41.9%. The most common QAV subtype was type B (48.4%). Technical success was achieved in 100% of the cases, with two cases reporting coronary obstruction and one required a permanent pacemaker implantation. During a median follow-up period of 1 year (from 30 days to 7 years), one case experienced serious complications of delayed coronary obstruction. Conclusion: The TAVR may be an alternative treatment for patients with QAV, preliminarily demonstrating feasible early and long-term results from current experience. However, extra precautions regarding coronary artery obstruction complications are necessary due to the rarity and anatomical complexity of QAV.

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:A 57 year old female underwent transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. Mild iatrogenic mitral stenosis was noted intraoperatively. Attempts to reposition the device were hampered by aortic angulation. One year later, severe mitral stenosis was confirmed on transoesophageal echocardiography. It is important to recognise that iatorgenic mitral stenosis due to TAVR may progress over time. Care should be taken to minimise the risk of this rare complication.

Project description:BackgroundThough the co-prevalence of aortic stenosis (AS) and cardiac amyloidosis (CA) is increasingly recognized, the role of transcatheter aortic valve replacement (TAVR) in patients with CA remains unclear.MethodsThe National Readmission Dataset (2016-18) and ICD-10 codes were used to identify those with CA and AS, in conjunction with TAVR status. The primary outcome was a composite of heart failure (HF) readmissions and all-cause mortality. All outcomes were followed up to 1-year with a median follow up time 172-days. Kaplan-Meier curves and multivariate cox-proportional hazard regression were used for time-to-event analysis.ResultsOf 1,127 CA patients, 92 (8.2%) had undergone TAVR. Patients with CA who received TAVR were younger and more commonly had coronary artery disease (67.3% vs 44.2%). Teaching (93.6% vs 81.1%) and large hospitals (77.7% vs 59.3%) performed more TAVRs. In multivariate analysis, TAVR was associated with an improved primary outcome (8.9% vs 24.4%, HR:0.32; 95% CI 0.14-0.71, p = 0.007) and with reduced HF readmissions (3.8% vs 19.4%, HR:0.22; 95% CI 0.07-0.68, p = 0.008). All-cause mortality was numerically lower in TAVR patients with CA but did not reach statistical significance.ConclusionsCA patients who receive TAVR are younger, and the procedure is more commonly performed at large, teaching hospitals. TAVR was associated with a lower primary composite outcome of HF readmissions and all-cause mortality.
