Comments of results after surgical replacement of mechanical mitral and aortic valve in children at Hanoi Heart Hospital
Main Article Content
Abstract
Objective: Assessment of early results after surgical treatment of mechanical mitral valve and aortic valve replacement in children at Hanoi Heart Hospital from 2004 to June 2019.
Methods: Analysis and evaluation based on data collected from patients undergoing surgery and from the results of follow-up examination.
Results: The total number of patients was 50, in which 34 cases of simple mechanical mitral valve replacement, 16 cases of simple mechanical aortic valve replacement. Average age of surgery: 7.58 ± 6.01 years (The lowest age is 7 months, the highest is 15 years). Male: 29 patients (58%), female: 21 patients (42%). Ultrasound before discharge and after 3 months, we found similar results: mean EF: mechanical mitral valve: 56.28 ± 10.67 %; Aortic valve: 54.72 ± 9.66% .Mean pressure : Mitral valve: 3.18 ± 1.25; Aortic valve: 12.12 ± 3.25 mmHg. INR index: mitral valve : 2.58 ± 1.20; Aortic valve: 2.34 ± 0.92. Complications of valve replacement: 2 cases of mitral valve replacement after surgery 3 years and 4 years; There was 1 case of aortic valve 5 years after surgery. Death immediately after surgery: mitral valve: 2 cases (5.88%); aortic valve: 1 case (6.25%); Late death: After 2 years, there was 1 case of death after mitral valve replacement; After 4 years, there was 1 case of death after aortic valve replacement.
Conclusion: The results of heart valve replacement surgery in children are positive. It is necessary to have better equipment and experience in open heart surgery in low-birth-weight children in order to operate the disease as early and effectively as possible, in which the treatment of complications of heart failure and post-operative coagulopathy should be considered important.
