[Long-term results after cardiac valve replacement: 16 years follow-up of 190 patients].
According to STS/AATS guidelines 1988, we compared the long-term results after cardiac valve replacement (ReAVR 26, ReMVR 127, ReDVR 35, ReTVR 2, total 190 patients) with those after initial valve replacement (AVR 760, MVR 1, 001, DVR 431, TVR 22, total 2,214 patients). Actuarial survival (AS), reoperation free (RF) and freedom from all valve-related events (EF) at the 10th postoperative year were 74.6%, 100%, 70.1% after ReAVR, 84.2%. 97.8%, 75.8% after AVR, 82.9%, 91.4%, 75.8% after ReMVR, 86.5%, 91.7%, 70.7% after MVR. 78.4%, 92.9%, 63.2% after ReDVR, 82.8%, 95.6%, 73.8% after DVR, respectively. There was no significant difference of AS, RF and EF between ReVR and initial VR in any valve position. These results justify our current strategy of cardiac valve re-replacement.
