Abstract

1.Objective: To evaluate the clinical and paraclinical characteristics as well as the early surgical outcomes of patients with aortic valve stenosis treated at Hanoi Medical University Hospital during the period 2021–2024.

  1. Methods: A descriptive study was conducted on patients diagnosed with aortic valve stenosis who underwent surgery at Hanoi Medical University Hospital from January 2021 to December 2024.

3.Results: The study included 40 patients with a mean age of 63.7 ± 8.2 years; males accounted for 67.5%. The main symptom was chest pain (65%). NYHA class II before surgery was observed in 85%. All patients (100%) had a systolic murmur at the aortic valve area. Preoperative echocardiography showed left ventricular enlargement with LVM(g) 240.2 ± 75.2, and most patients had preserved left ventricular function, with 80% having EF >50%. All patients presented with severe aortic valve stenosis and ascending aortic dilatation, with a mean transvalvular gradient of 62.5 ± 16.1 and ascending aortic diameter of 40.5 ± 5.2 mm. A bicuspid aortic valve abnormality was found in 35 patients (87.5%). Surgical procedures included 17.5% with ascending aortic replacement, 40% with ascending aortic wrapping, and 7.5% with mitral valve repair using an annuloplasty ring. Postoperatively, 95% of patients were discharged with good outcomes; one patient died due to intraoperative Stanford type A aortic dissection leading to multiorgan failure, and one required reoperation for sternal reconstruction due to sternal dehiscence.

4.Conclusion: Aortic valve stenosis is predominantly observed in the elderly population, manifesting with a heterogeneous spectrum of cardiac symptoms, ascending aortic involvement, and comorbidity-related conditions. Surgical management primarily consists of aortic valve replacement combined with appropriate intervention on the ascending aorta, achieving a high rate of procedural success.
