Abstract

Objectives:To evaluate the early results of surgical treatment for aortic valve disease with mechanical valve replacement. Methods:A retrospective, descriptive case series study was conducted on 36 patients with aortic valve disease who underwent mechanical valve replacement at Military Hospital 103 from September 2019 to December 2024. Results:36 patients had an average age of 56.1 ± 10.2 years, ranging from 23 - 72; males accounted for 75%. Preoperative heart failure was presented in 58.3% of NYHA II and 41.7% of NYHA III. 11.1% of patients had aortic valve stenosis; 58.3% had aortic valve regurgitation; 30.6% had combined aortic stenosis and regurgitation. The aortic cross-clamp time and the cardiopulmonary bypass time were 158.1 ± 60.3 and 201.5 ± 77.3 minutes, respectively. 21 and 23 were the most commonly used valve sizes, accounting for 30.6% and 47.2%, respectively. Postoperatively, no death and third-degree atrioventricular block were noted; 1 case required intra-aortic balloon counterpulsation due to low cardiac output syndrome, 1 case required reoperation due to bleeding, and 1 case had wound infection. Conclusion:Mechanical aortic valve replacement represents a safe and effective method for the management of aortic valve disease, and a low rate of complications for patients with aortic valve disease.
