Comparison of Sutureless and Sutured Aortic Valve Replacements in Patients with Redo Infective Endocarditis

<i>Background and Objectives</i>: This study aims to assess the postoperative outcomes and complications of sutureless and sutured aortic valve replacement in patients with infective endocarditis. <i>Materials and Methods</i>: A total of 58 patients who underwent redo aortic valve replacement for bacterial or non-bacterial endocarditis between January 2018 and March 2023 were included in our study. Surgical procedures were performed through a full median sternotomy due to redo cases and to provide optimal access. Demographic characteristics, operative times, postoperative complications and some echocardiographic data were compared. All cases were meticulously evaluated preoperatively by a cardiac team to select the best treatment option. <i>Results</i>: The mean ICU length of stay was significantly shorter in the sutureless valve group at 5.4 ± 3.9 days compared to 7.9 ± 4.1 days in the sutured valve group (<i>p</i> = 0.029). However, the sutureless group had a mean operation time of 164.7 ± 37.3 min, while the sutured group had a mean operation time of 197.7 ± 45.6 min (<i>p</i> = 0.044). Again, the difference in cardiopulmonary bypass times between the two groups was statistically significant (<i>p</i> = 0.039). And again, four (14.2%) patients in the sutureless group underwent reoperation due to bleeding, while eight (26.6%) patients in the sutured group underwent postoperative bleeding control (<i>p</i> = 0.048). <i>Conclusions</i>: Our study suggests that sutureless aortic valve replacement may offer advantages in terms of operative efficiency and postoperative recovery compared to conventional sutured valves, with some significant differences in terms of some complications.
