Early and mid-term functional and survival benefits in ischaemic versus degenerative mitral valve repair using Duran flexible ring: a single surgeon series.
Interactive cardiovascular and thoracic surgery(2009)
摘要
The late results of ischaemic mitral valve (MV) repair have been less than satisfying. We compared echocardiographically, the changes in LV function, mid-term durability and survival between MV repair caused by ischaemic cardiomyopathy (n=60) with degenerative MV disease (n=73) over a period of 15 years. The duration of mean follow-up was 3.7+/-4.1 years in the ischaemic group and 3.9+/-2.9 years in the degenerative group. Freedom from reoperation at seven years was 98.3%+/-1.5% and 98.9%+/-2.1%, respectively (P=0.889). At the last follow-up, NYHA functional class I or II was present in 78.4% of patients in the ischaemic group and 80.9% patients in the degenerative group (P=0.347). An improvement in LVEF was noted in both the groups: ischaemic--41.3+/-12.7 (pre-op LVEF: 38.8+/-14.1) and degenerative--46.5+/-11.1 (pre-op LVEF: 45.7+/-11.7) (P=0.014). At seven years, freedom from a cardiac cause of death was statistically similar in the two groups: 93.3%+/-1.3% and 92.2%+/-0.6% (P=0.967). In conclusion, the mid-term results of ischaemic MV repair are similar to those obtained for degenerative MV repair. Surgical correction of ischaemic MR results in long-term improved LVEF and comparable outcomes in terms of freedom from reoperation and survival.
