Outcomes of Valve-Sparing Aortic Root Replacement (David I Procedure) at a Single Center in Kazakhstan.

Valve-sparing aortic root replacement, commonly known as the David procedure, stands as a pioneering surgical technique aimed at addressing aortic root aneurysms while retaining the patient's native aortic valve. This procedure signifies a significant advancement in cardiac surgery, offering patients the potential for improved outcomes both in the short and long term. Aims. The aim of the study was to analyze short- and long-term outcomes after valve sparing aortic root replacement operation using David I technique. Methods. From January 2013 to November 2020 a total 124 David I procedures were performed. We analyzed survival and freedom from reoperation. Follow-up was performed 8 years postoperatively. Results. Early mortality was 0.8% (n = 1). Mean age was 48.25 ± 17.42. The left ventricular ejection fraction (%) before discharge was significantly increased (p = 0.038) after surgery. The 1, 3, 6, 8 –year survival and freedom from reoperation rates were 99%, 99%, 98%, 87% and 99%, 98%, 95%, 91% retrospectively. Conclusion. David procedure is a valuable option for treating aortic root aneurysms offering the potential for excellent long-term outcomes, especially when the native aortic valve can be preserved. The decision should be made on a case-by-case basis, considering the patient's individual factors and the expertise of the surgical team.
