Novel concept of less invasive concomitant surgical aortic valve replacement and coronary artery bypass grafting avoiding full median sternotomy

AbstractIn the last decades, minimally invasive procedures have been developed in the therapy of aortic valve disorders. Recently, a novel concept of minimally invasive coronary revascularization in multivessel disease via left anterior mini-thoracotomy demonstrated promising results. Full median sternotomy, as a very invasive procedure, is the standard approach in concomitant surgical aortic valve replacement (sAVR) and coronary bypass grafting (CABG). The aim of our study was to show that the combination of minimal invasive aortic valve replacement via upper mini-sternotomy and coronary artery bypass grafting via left anterior mini-thoracotomy is feasible to avoid full median sternotomy. From 07/2022 to 09/2022, concomitant sAVR via upper partial sternotomy and CABG via left anterior mini-thoractomy on cardiopulmonary bypass and cardioplegic arrest was successfully performed in six consecutive patients (6 males; 69.8  ± 7.4 [60–79] years). All patients had severe aortic stenosis (MPG 45.5 ± 17.3 mmHg) and a significant coronary artery disease (three-vessel: 33%, two-vessel: 33%, one-vessel: 33%) with indication to cardiac surgery. Mean EuroScore2 was 3.2. All patients underwent successful less invas ive concomitant biological sAVR and CABG. 67% of patients received a 25 mm, 33% received a 23 mm biological aortic valve replacement (Edwards Lifesciences Perimount). A total of 11 distal anastomoses (1.8 ± 1.0 [1–3] per patient) were performed by using lef...
