Mid-term results of surgical aortic valve replacement for aortic stenosis at 108 Military Central Hospital

Tóm tắt

Objective: To study on medium-term results after aortic valve replacement surgery for aortic stenosis (AS) at 108 Military Central Hospital. Subject and method: 67 patients with AS received aortic artificial valves replacement. The results collected at the time of 3, 6, 12, 24, 36 and 48 months include: NYHA class, echocardiography (LVEDd, LVEDs, AVA, mean PG), Sokolow-Lyon, PPM and complications. Evaluation is based on the criteria of the Vietnam National Heart Association and the Guidelines of the ACC/AHA. Result: NYHA 1 was increased (76.1%) and NYHA 2 - 3 was 23.9% with p<0.05 in 6 months and an increasing trend at later times (p>0.05). Sokolow-Lyon index < 35mm after surgery > 90%, mid-term echocardiography AVA about 1.6cm², LVEF > 60%, mean PG < 20mmHg, LVEDd and LVEDs within normal limits. Hemorrhagic complications, stuck aortic valve (≤ 3.8%), fuite paraprosthetiques did not appear after 6 months. Conclusion: The medium-term outcome after aortic valve replacement for aortic stenosis has good clinical and subclinical improvement and the rate of medium-term complications is low.
