Abstract

Summary: The rate of mitral valve reoperation following prior valve repair ranges from approximately 4.5% to 8% over 10 years, and this rate has increased over the past decade. Mitral valve reoperation is a complex procedure because the anatomical structure of the heart changes after the initial surgery. This presents a challenging task for the surgeon, requiring advanced expertise and skill to separate each structure without causing damage, which increases the risk of tearing or rupture, potentially leading to bleeding and, in some cases, death. Therefore, we conducted this study to evaluate the early outcomes of mitral valve replacement following prior mitral valve repair at Tam Duc Heart Hospital from March 2006 to June 2023.


Study subjects and methods: A retrospective study describing a series of cases from March 2006 to June 2023.


Results: After mitral valve replacement, 39 patients showed improvement in NYHA classification, heart rate, pulmonary artery pressure, left atrial diameter, left ventricular diastolic diameter, and transvalvular pressure gradient. One patient died postoperatively on day 50. Early postoperative complications mainly included reoperation for bleeding (12.8%), pneumonia (10.3%), and kidney failure requiring hemodialysis (7.7%).


Conclusion: The early outcomes of mitral valve replacement following prior mitral valve repair at Tam Duc Heart Hospital were positive, with few complications and low early mortality rates post-surgery.
