Objective Right anterior minithoracotomy is a promising technique for aortic valve replacement and has shown excellent results in terms of mortality and morbidity. Against this background, we analyzed our institutional experience in this technique during the last 3 years. Methods Between April 2017 and March 2019, 513 consecutive all comers with aortic valve disease underwent video-assisted minimally invasive aortic valve replacement through a 3-cm skin incision as right anterior minithoracotomy at our institution. A camera and automatic fastener technology were used for the valve implantation in all patients. Clinical data were prospectively entered into our institutional database. Results Cardiopulmonary bypass time accounted for 68 ± 24 min and the myocardial ischemic time 38 ± 12 minutes. Thirty-day mortality and overall mortality was 0.4% (2 patients) and 1.4% (7 patients), respectively. Postoperative cerebrovascular events were noted in 8 patients (1.5%). Intensive care stay and hospital stay were 2 ± 2 and 9 ± 7 days, respectively. Pacemaker implantation, injury of the right internal mammary artery, and conversion to full sternotomy were noted in 7 patients (1.4%), 3 patients (0.6%), and 1 patient (0.2%), respectively. Paravalvular leak need to intervention was noted in 2 patients (0.4%). Rethoracotomy rate was 2% (11 patients). Transient postoperative dialysis was necessary for 14 patients (3%). Conclusions Video-assisted minimally invasive aortic valve replacement through the right anterior minithoracotomy is a safe approach and yields excellent outcomes in high-volume centers. The use of a camera and automatic fastener technology facilitates this procedure.
