In 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 invasive 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 left internal artery mammary (50%), radial artery (17%) and saphenous venous graft (67%) for grafting the left anterior descending (83%), circumflex (67%) and right (33%) coronary artery. Hospital mortality was 0%, stroke rate was 0%, myocardial infarction was 0% and repeat revascularization rate was 0%, ICU stay was 1 day in 83% of all patients and 50% left hospital within 8 days after surgery. Less invasive concomitant surgical aortic valve replacement and coronary artery bypass grafting using upper mini-sternotomy and left anterior mini-thoracotomy is feasible without compromises in surgical principles and complete coronary revascularization while maintaining thoracic stability by avoiding full median sternotomy.
