Introduction:
Due to their favourable hemodynamic performance and the ability to enable minimally invasive access procedures, sutureless aortic valve prostheses have found their place in the armamentarium of cardiothoracic surgeons. In this study, we sought to review our institutional experience of sutureless aortic valve replacement (SU-AVR).
Methods:
We carried out a retrospective analysis of 200 consecutive patients who underwent an SU-AVR with a Perceval valve between December 2019 and February 2023.
Results:
The mean age of patients was 69.3 ± 8.1 years, and patients showed a moderate-risk profile with a mean logistic EuroSCORE-II of 5.2 ± 8.1%. An isolated SU-AVR was performed in 85 (42.5%) patients, concomitant CABG was performed in 75 (37.5%) and 40 patients (20%) underwent a multivalve procedure involving SU-AVR. The cardiopulmonary bypass (CPB) and cross-clamp (CC) times were 82.1 ± 35.1 and 55.5 ± 27.8 min, respectively. In-hospital, 30-day, 6-month and 1-year mortality rates were 4.5%, 6.5%, 7.5% and 8.2%, respectively. The postoperative transvalvular mean pressure gradient was 6.3 ± 1.6 mmHg and stayed stable over the follow-up time. We reported no cases of paravalvular leakage, and the incidence of stroke was 0.5%.
Conclusions:
With their favourable hemodynamic performance and shorter CC and CPB times, sutureless aortic valve prostheses facilitate minimally invasive access surgery, being a safe and durable promising approach for the surgical AVR.
