Abstract:
Objective To summarize the results of valve re-operative cases after cardiac valve replacement, to find the better re-operative time, and to estimate the re-operative methods and influencing factors of the operation. Methods Thirteen valve re-operative cases after cardiac valve replacement from October 2008 to February 2010 were retrospectively studied. According to NYHA classification, 9 cases belonged to class Ⅳ, and only 4 cases belonged to class Ⅲ preoperatively. Mitral valve replacement (MVR)was performed in 7 cases, aortic valve replacement (AVR) in 3 cases, MVR + AVR in 3 cases. Results The early-stage postoperative mortality was 7.7%( 1/13),and the reason was low cardiac output syndrome. Two cases who underwent re-operation and re-intubation respectively after operation for hemorrhage were improved after treatment. Twelve cases were discharged in 3-6 weeks after heart valve surgery and all were followed up for 6-15 months. The cardiac function of all the discharged patients recovered well and no death occurred during follow-up. Conclusion The key factors to reduce the death of re-operation are improving preoperative heart function,setting up extracorporeal circulation as soon as possible,consummating myocardial preservation,perfecting operating skills,correcting low cardiac output syndrome in time and preventing complications.
