Objective To evaluate the clinical effect of minimally invasive aortic valve replacement with Perceval sutureless aortic bioprosthesis in upper ministernotomy or right anterior thoracotomy. MethodsFrom March to November 2022, the patients with simple aortic valve disease were enrolled in the Department of Cardiovascular Surgery of West China Hospital, Sichuan University. After preoperative evaluation, Perceval sutureless bioprosthesis was successfully used to perform aortic valve replacement through the upper ministernotomy or right anterior thoracotomy. The perioperative clinical data and ultrasonic measurement data of all patients were recorded. ResultsA total of 5 patients with simple aortic valve disease were included, including 3 females and 2 males, with a mean age of 71.2 years. Perceval sutureless bioprosthesis was successfully implanted in 5 patients, with a success rate of 100%. There were 3 patients receiving upper ministernotomy and 2 patients receiving right anterior thoracotomy. Two patients underwent ascending aortic plasty at the same time. The mean cardiopulmonary bypass time was 61.0 min, and aortic cross-clamping time was 32.2 min. All patients were discharged successfully without perivalvular leakage, atrioventricular block or stroke. ConclusionThe implantation method of Perceval sutureless bioprosthesis is simple, which can effectively reduce the perioperative risk by shortening the overall operation time, cardiopulmonary bypass time and aortic cross-clamping time. At the same time, its clinical application has promoted the development and popularization of minimally invasive aortic valve replacement, which together with Perceval sutureless bioprosthesis effectively combinates surgical effect and minimally invasive treatment, and has a good clinical application prospect because of its reliable safety and effectiveness.
