RESUMEN
Objective To investigate the operation experience of reducing time of heart clamp in double valve replacement and tricuspidplasty in 66 patient. Methods From May 1999 to March 2003, 66 patients received mitral valve replacement(MVR), aortic valve replacement(AVR) and tricuspidplasty. Mitral valves were replaced by continuous suture. Aortic valves were replaced by continuous suture in 59 cases and interrupted suture in 7 cases. Results 132 artificial valves were grafted. The time of aortic clamp and pump was 34.5?4.3 minutes and 56.1?7.8 minutes respectively. There were no postoperative severe complications and death in all 66 cases in hospital. Conclusions Decreasing the time of aortic clamp and pump is good for myocardium protection and may reduce postoperative complications.
