Abstract Background Rapid deployment aortic valve replacement (RDAVR) and transcatheter aortic valve implantation (TAVI) have emerged as increasingly used alternatives to conventional aortic valve replacement to treat patients at higher surgical risk. Therefore, in this single-center study, we retrospectively compared clinical outcomes and hemodynamic performance of two self-expanding biological prostheses, the sutureless and rapid deployment valve (RDV) Perceval-S (PER) and the transcatheter heart valve (THV) ACURATE neo/TF (NEO) in a 1:1 propensity-score-matching (PSM) patient cohort. Methods A total of 332 consecutive patients with symptomatic aortic valve stenosis underwent either singular RDAVR with PER (119) or TAVI with NEO (213) at our institutions between 2012 and 2017. To compare the unequal patient groups, a 1:1 PSM for preoperative data and comorbidities was conducted. Afterward, 59 patient pairs were compared with regard to relevant hemodynamic parameter, relevant paravalvular leak (PVL), permanent postoperative pacemaker (PPM) implantation rate, and clinical postoperative outcomes. Results Postoperative clinical short-term outcomes presented with slightly higher rates for 30-day all-cause mortality (PER = 5.1% vs. NEO = 1.7%, p = 0.619) and major adverse cardiocerebral event in PER due to cerebrovascular events (transient ischemic attack [TIA]-PER = 3.4% vs. TIA-NEO = 1.7%, p = 0.496 and Stroke-PER = 1.7% vs. Stroke-NEO = 0.0%, p = 1). Moreover, we show comparable PPM rates (PER = 10.2% vs. NEO = 8.5%, p = 0.752). However, higher numbers of PVL (mild—PER = 0.0% vs. NEO = 55.9%, p = 0.001; moderate or higher—PER = 0.0% vs. NEO = 6.8%, p = 0.119) after TAVI with NEO were observed. Conclusion Both self-expanding bioprostheses, the RDV-PER and THV-NEO provide a feasible option in elderly and patients with elevated perioperative risk. However, the discussed PER collective showed more postoperative short-term complications with regard to 30-day all-cause mortality and cerebrovascular events, whereas the NEO showed higher rates of PVL.

Abstract Background The role of conventional surgical aortic valve replacement (SAVR) is increasingly questioned since the indication for transcatheter aortic valve implantations (TAVIs) is currently extended. While the number of patients referred to SAVR decreases, it is unclear if SAVR should be performed by junior resident surgeons in the course of a heart surgeons training. Methods Patients with isolated aortic valve replacement (AVR) were analyzed with respect to the surgeon's qualification. AVR performed by resident surgeons was compared with AVR by senior surgeons. The collective was analyzed with respect to clinical short-term outcomes comparing full sternotomy (FS) with minimally invasive surgery and ministernotomy (MS) with right anterior thoracotomy (RAT) after a 1:1 propensity score matching. Results The 30-day all-cause mortality was 2.3 and 3.4% for resident versus senior AVR groups, cerebrovascular event rates were 1.1 versus 2.6%, and no cases of significant paravalvular leak were detected. Clinical short-term outcomes between FS and minimally invasive access, as well after MS and RAT were comparable. Conclusion Our current data show feasibility and safety of conventional SAVR procedure performed by resident surgeons in the era of TAVI. Minimally invasive surgery should be trained and performed in higher volumes early in the educational process as it is a safe treatment option.
