Reoperation
Throughout the follow-up period only one patient required re-intervention on the aortic root at 3 years following the index procedure (mechanical CVG). This was due to recurrent mediastinitis resulting in a false aneurysm around the left coronary button and dehiscence of the proximal suture-line. The patient died shortly after the re-intervention. No patient from the PAR required re-intervention within the 5-year follow-up period.
