ObjectiveTo summarize the approaches and experience of 118 cases of re-valve replacement surgery. MethodsThe clinical data of 118 patients requiring re-valve replacement surgery after definitive diagnosis confirmed by echocardiography were analyzed retrospectively, including 12 cases of mitral and aortic valve replacement, 31 cases of aortic valve replacement, 70 cases of mitral valve replacement, and 5 cases of tricuspid valve replacement. The causes of re-valve replacement surgery were as follows: mechanical valve failure in 62 cases, perivalvular leakage in 27 cases, bioprosthetic valve failure in 26 cases, and bioprosthetic valve dysfunction in 3 cases. ResultsEight cases died during the perioperative period, with a mortality of 6.8%. The causes of death were multiple organ failure, malignant arrhythmia, and severe low cardiac output syndrome. Postoperative complications occurred in 19 cases, with an incidence rate of 16.1%. ConclusionCompared with the first valve operation, re-valve replacement surgery has great difficulty in operation, heavy blood loss, and high incidence rate of postoperative complications and mortality. The major causes of re-valve surgery are mechanical valve failure, perivalvular leakage, and bioprosthetic failure.
