Ten-year experience with sutureless Perceval bioprosthesis: single-centre analysis in 1157 implants.

AIMS: We describe long-term clinical and echocardiographic outcomes in the largest single-centre cohort of patients who underwent aortic valve replacement (AVR) with sutureless Perceval (CorCym, Italy) bioprosthesis.

METHODS

Between March 2011 and March 2021, 1157 patients underwent AVR with Perceval bioprosthesis implantation. Mean age was 77 ± 6 years (range: 46-89 years) and mean EuroSCORE II was 6.7 ± 3.2% (range: 1.7-14.2%). Concomitant procedures were performed in 266 patients (23%).

RESULTS

Thirty-day mortality was 1.38% (16/1157). Eight hundred and twenty of 891 (92%) isolated AVRs underwent minimally invasive surgery with a ministernotomy ( n  = 196) or right minithoracotomy ( n  = 624) approach. Cardiopulmonary bypass and aortic cross-clamp times were 81.1 ± 24.3 and 50.6 ± 11.7 min for isolated AVR and 144.5 ± 34.7 and 96.4 ± 21.6 min for combined procedures. At mean follow-up of 53.08 ± 6.7 months (range: 1-120.5 months), survival was 96.5% and mean transvalvular pressure gradient was 13.7 ± 5.8 mmHg. Left ventricular mass decreased from 152.8 to 116.1 g/m 2 ( P  < 0.001) and moderate paravalvular leakage occurred in three patients without haemolysis not requiring any treatment. Freedom from reoperation was 97.6%. Eight patients required surgical reintervention and 19 patients transcatheter valve-in-valve procedure for structural prosthesis degeneration at a mean of 5.6 years after first operation (range: 2-9 years).

CONCLUSION

AVR with a Perceval bioprosthesis is associated with good clinical results and excellent haemodynamic performance in our 10-year experience. Structural degeneration rate of Perceval is comparable with other bioprosthetic aortic valves. Sutureless technology may reduce operative time especially in combined procedures and enable minimally invasive AVR.
