Abstract

Objective: Evaluate early results after mitral valve replacement surgery at Hanoi Medical University Hospital. Results: From 10/2019 to 05/2022, 43 patients with heart valve disease had gone through  mitral valve replacement at the Cardiothoracic - Thoracic Operations Unit of Hanoi Medical University Hospital with heart valve disease and were eligible to participate in the study with the average age is 55.6 ± 10.7. Before surgerys, 34.9% of patients had a history of percutaneous balloon mitral valvuloplasty, 39.5% of patients had NYHA class III, IV, the cardiothoracic ratio 0.6 ± 0.07, average of EF 58.1 ± 8.5%, and pulmonary pulse pressure 48.2 ± 15.7 mmHg. In the surgerys, 74.4% of patients received mechanical valve replacement, 62.8% of patients received bilateral tricuspid repair, 46.5% of patients is  sutured auricle of left atrium. CPB mean time 109.0 ± 20.7 minutes, and clamping the aorta 83.0 ± 21.8 minutes. After surgerys, the average time of the ventilator was 25.5 ± 20.8 hours, the average time in the ICU was 3.5 ± 1.3 days and an average  time after surgery of 12.8 ± 6.2 days. 79,1% saw an improvement in their NYHA, and 1 patient (2.3%) had to drain the pleural cavity because of hemoptysis. 1 patient (2.3%) had to be hospitalized for anticoagulation adjustment, 1 patient (2.3%) had to undergo reoperation because of bleeding. There were no cases of death due to primary vascular disease. Conclusion: Mitral valve replacement surgery at Hanoi Medical University hospital is bringing positive results with a low rate of complications and mortality and safety.
