Abstract

Objective: To review some clinical and echocardiographic characteristics of patients received aortic mechanical valves replacement at 108 Military Central Hospital. Subject and method: 67 patients with aortic stenosis (AS) received aortic mechanical valves replacement. Clinical and echocardiographic based on the criteria of the Viet Nam National Heart Association and ACC/AHA guidelines. Result: Anamnesis of rheumatic heart disease was 62.7% (no treatment was 16.4%), Hypertension was 35.8%, NYHA 2 and 3 were 100%, fainting was 26.9%, chest pain on exertion was 59.7%. Echocardiography: Severe aortic stenosis valve was 97%, mean gradient pressure > 40mmHg was 95.5%, left ventricular hypertrophy (308.7 ± 35.3g) but left ventricular systolic function is preserved. Conclusion: Clinical symptoms of aortic stenosis were not obvious, chest pain on exertion was 59.7%, fainting was 26.9%. Echocardiography: severe stenosis of the aortic valve by area accounted for 97% and according to mean gradient pressure was 95.5%. Left ventricular hypertrophy with a mean muscle mass of 308.7 ± 35.3g.
