Surgical procedures characteristics
We performed 16(42%) AVRec surgery as single procedure and 22(58%) with another associated procedure (Table 2A). In 6 patients we performed mitral valve (MV) repair surgery and in two mechanical MV replacement (the first intention was to repair the MV with the aim of avoiding OAC therapy). Six patients (16%) had coronary artery disease with indication for CABG, however, 2 more underwent CABG due to suspected intraoperative coronary embolism (total CABG, 21%). In eight patients (21%) we performed ascending aortic surgeries, seven underwent ascending aorta replacements and one underwent AV re-implantation surgery (David procedure + AVRec surgery).
The median of Cardiopulmonary bypass (CPB) time was 147 minutes (IQR 46), the median of aortic cross clamp time was 120 (IQR 45), when we include AVRec surgery as a single procedure these times were 136 minutes (IQR 49) and 104 minutes (IQR 37), respectively.
