Sutureless aortic valve replacement in pure aortic regurgitation : expanding the indications

Background: In the era of transcatheter methods, patients presenting with a pure aortic regurgitation (AR) are not considered eligible for transcatheter treatment and therefore require another less invasive surgical option. We sought to review our experience with sutureless aortic valve replacement (SU-AVR) in patients presenting with symptomatic pure AR, which until now is a contraindication for implementation of sutureless valve prostheses in Europe.

Methods: Between April 2018 and June 2021, 80 consecutive patients underwent a SU-AVR for various indications at our institution. We analyzed the outcomes and postoperative complications of 12 patients presenting with a pure severe AR undergoing SU-AVR using Perceval (Corcym).

Results: The mean age of the patients was 67 ± 9.1 years old. All patients presented with symptomatic pure AR. Patients presented with multiple comorbidities as reflected by the mean EuroSCORE-II of 3.6 ± 2.6%. Six patients (50%) underwent a concomitant CABG procedure. The mean operating- and cross clamp time was 127.25 ± 45.9 and 40.33 ± 17.3 min respectively. All isolated SU-AVR were performed via J-sternotomy or right anterolateral thoracotomy. There were no cases of device dislocation. No patients presented with a paravalvular leakage. We observed excellent mean postoperative pressure gradient at follow-up 5.7 ± 1.5 mmHg.

Conclusions: Our experience with SU-AVR shows the feasibility of sutureless technologies in the aortic valve surgery due to pure AR. Besides the great technical success and excellent hemodynamics, SU-AVR in severe AR offers a great opportunity of reducing the invasivity of the surgical procedure and potentially reducing hospital cost without compromising the postoperative outcomes and in-hospital length of stay.
