Đánh giá hiệu quả phẫu thuật thay van hai lá cơ học theo thang điểm Kansas City Cardiomyopathy - 12 tại Bệnh viện Hữu nghị Đa khoa Nghệ An

Abstract

We conducted a cohort study on adult patients undergoing mechanical mitral valve replacement surgery at Nghe An General Friendship Hospital from June 2022 to March 2024. We analyzed the main postoperative outcomes including: KCCQ-12 score (Kansas City Cardiomyopathy Questionnaire -12), mortality rate and readmission rate in 6 months after surgery. A total of 67 patients with symptomatic mitral stenosis or regurgitation disease were included in the study. Patients had a average age of 52.3 ± 9.4 years old, 73.64% were female, 50.75% had decreased ejection fraction (< 60%). After 6 months of valve replacement surgery, patients had a mortality rate of 1.47%, a readmission rate of 35.82%, and KCCQ overall score of 84.3 ± 13, and KCCQ clinical summary score of 84 ± 12.7. The average KCCQ-12 score increased by 28 - 48 points in all domains, with the greatest increase in the improvement of patients' quality of life. Mechanical mitral valve replacement surgery is a effective treatment method with low complication rate, improving heart failure symptoms in patients with mitral valve disease. KCCQ-12 score is an effective tool to assess changes in symptoms and quality of life in patients after mitral valve replacement surgery.
