A 77-year-old man with a history of coronary artery bypass grafting and surgical aortic valve replacement for severe aortic stenosis 2 years prior presented with exertional chest pain and shortness of breath. The patient underwent a thorough initial evaluation including a transthoracic echocardiogram and coronary angiogram without significant findings. One month later the patient presented with worsened symptoms and a repeat echocardiogram showed an increased mean aortic valve gradient of 87 mm Hg. The patient had to undergo reoperation for a surgical aortic valve replacement and was found to have an aortic bioprosthetic valve thrombus. This case suggests a mismatch between the aortic prosthesis and the patient’s aortic root size.

Abstract Introduction Sutureless biological valves for surgical aortic valve replacement (SAVR), characterized by the absence of anchoring sutures at the aortic annulus, are gaining popularity because of ease and reproducibility of implant, shorter operating times, and enhancement of minimally invasive approaches. The stentless configuration of the sutureless valve was designed to achieve optimal hemodynamic performance. Materials and Methods PERSIST-AVR (PERceval Sutureless Implant versus STandard Aortic Valve Replacement) is a prospective, randomized, adaptive, open-label, international, postmarket trial (NCT02673697). The primary objective of the trial is to assess the safety and efficacy of the Perceval (LivaNova, London, UK) sutureless bioprosthesis among patients undergoing SAVR in the presence of severe aortic stenosis to demonstrate the noninferiority of Perceval as compared with standard sutured stented bioprosthetic aortic valve as an isolated procedure or combined with coronary artery bypass grafting. Sample size will be determined adaptively through interim analyses performed by an Independent Statistical Unit till a maximum of 1,234 patients, enrolled at ∼60 sites in countries where the device is commercially available. Patients will be followed up for 5 years after implant. The primary end point is the number of patients free from major adverse cardiac and cerebrovascular-related events at 1 year. Additional secondary outcomes will be assessed up to 5 years. Discussion PERSIST-AVR is the first prospective, randomized study comparing in-hospital and postdischarge outcomes in a robust population of patients undergoing SAVR with either the Perceval sutureless bioprosthesis or a conventional sutured stented bioprosthesis up to 5 years.

Background Aortic stenosis requires timely treatment with either surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). This study aimed to investigate the indirect impact of COVID-19 on national SAVR and TAVR activity and outcomes. Methods The UK TAVR Registry and the National Adult Cardiac Surgery Audit were used to identify all TAVR and SAVR procedures in England, between January 2017 and June 2020. The number of isolated AVR, AVR+coronary artery bypass graft (CABG) surgery, AVR+other surgery and TAVR procedures per month was calculated. Separate negative binomial regression models were fit to monthly procedural counts, with functions of time as covariates, to estimate the expected change in activity during COVID-19. Results We included 13376 TAVR cases, 12328 isolated AVR cases, 7829 AVR+CABG cases, and 6014 AVR+Other cases. Prior to March 2020 (UK lockdown), monthly TAVR activity was rising, with a slight decrease in SAVR activity during 2019. We observed a rapid and significant drop in TAVR and SAVR activity during the COVID-19 pandemic, especially for elective cases. Cumulatively, over the period March to June 2020, we estimated an expected 2294 (95% CI 1872, 2716) cases of severe aortic stenosis who have not received treatment. Conclusion This study has demonstrated a significant decrease in TAVR and SAVR activity in England following the COVID-19 outbreak. This situation should be monitored closely, to ensure that monthly activity rapidly returns to expected levels. There is potential for significant backlog in the near-to-medium term, and potential for increased mortality in this population.

AbstractTranscatheter aortic valve replacement (TAVR) has shown to reduce mortality compared to surgical aortic valve replacement (sAVR). However, it is unknown which procedure is associated with better post-procedural valvular function. We conducted a meta-analysis of randomized clinical trials that compared TAVR to sAVR for at least 2 years. The primary outcome was post-procedural patient-prosthesis-mismatch (PPM). Secondary outcomes were post-procedural and 2-year: effective orifice area (EOA), paravalvular gradient (PVG) and moderate/severe paravalvular leak (PVL). We identified 6 trials with a total of 7022 participants with severe aortic stenosis. TAVR was associated with 37% (95% CI [0.51–0.78) mean RR reduction of post-procedural PPM, a decrease that was not affected by the surgical risk at inclusion, neither by the transcatheter heart valve system. Postprocedural changes in gradient and EOA were also in favor of TAVR as there was a pooled mean difference decrease of 0.56 (95% CI [0.73–0.38]) in gradient and an increase of 0.47 (95% CI [0.38–0.56]) in EOA. Additionally, self-expandable valves were associated with a higher decrease in gradient than balloon ones (beta = 0.38; 95% CI [0.12–0.64]). However, TAVR was associated with a higher risk of moderate/severe PVL (pooled RR: 9.54, 95% CI [5.53–16.46]). All results were sustainable at 2 years.
