Comparison of semi-continuous and interrupted suture technique for aortic valve replacement

Results The number of patients underwent AVR including combined cardiac procedures was 1005 with semi continuous technique (group 1) and 1110 with interrupted technique (group 2). The hospital mortality was 4.68% in group 1 and 3.96% in group 2. Cardiopulmonary bypass (CPB) time and aortic cross clamp (XC) time for isolated AVR was 89 ± 42 (41 – 379) and 63 ± 31 (29 – 258) in group 1, 98 ± 34 ( 44 – 377) and 72 ± 26 (30 – 236) in group 2, p=0.0002, p<0.0001, respectively. Late cardiac reoperation was performed in 23 patients (2.3%) in group 1 and in 24 patients (2.2%) in group 2. Late repeat operation for AVR was performed in 5 patients (0.5%) in group 1, and in 5 patients (0.45%) in group 2. There were 51 late deaths (10.9%) group 1 and 48 late deaths (9.2%) in group 2.
