Minimally invasive aortic valve repair using geometric ring annuloplasty

Objectives As aortic valve repair (AVr) for aortic insufficiency (AI) expands, minimally invasive (Mi) approaches are increasingly being applied. Cardiac surgical techniques can be more difficult through small incisions, and this report analyzes medium‐term outcomes for MiAVr facilitated by geometric ring annuloplasty. Methods Since 2013, 58 patients were selected for AVr through upper sternotomy third‐interspace incisions. The average age was 58.9 ± 15.4 (mean ± SD) years, 71% were male, and preoperative AI grade was 3.6 ± 0.8. Sixty‐two percent (36/58) had a proximal aortic replacement for ascending aortic aneurysms (n = 26) and/or remodeling grafts for aortic root aneurysms (n = 10). Annuloplasty rings were placed subannularly (69% trileaflet; 31% bicuspid), and leaflet procedures were performed in 70%. The average ring diameter was 21.6 ± 1.4 mm, and the average aortic clamp time was 113 ± 35 min. Results After repair, AI grade fell to an average of 0.5 ± 0.6 (p
