Background: In this study, we compared the early outcomes of sutureless aortic valves versus conventional stented bioprosthetic valves.

Methods: Between October 2009 and May 2014, 46 patients (22 males, 24 females; mean age 74.74±7.35 years; range 56 to 87 years) were included. The patients were divided into two groups including 25 patients with conventional stented bioprosthetic valves in group 1 and 21 patients with sutureless aortic valves in group 2.

Results: The maximum postoperative aortic gradient was 20.1±5.5 mmHg for the sutureless group and 28.7±13.9 mmHg for the stented group (p=0.038). The mean postoperative gradient was 10.3±3.4 mmHg for the sutureless group and 15.1±8.4 mmHg for the stented group (p=0.052). No in-hospital mortality was seen in the sutureless group; however, five patients in the stented group died during the hospital stay (p=0.054).

Conclusion: Sutureless aortic valve replacement is a novel surgical treatment modality, yielding excellent hemodynamic conditions with a short ischemic time.
