| Popis: | Early results of mitral valve replacement were reviewed in 336 unselected patients, 261 without and 75 with concomitant coronary artery bypass grafting (MVR and MVR + CABG groups). Early (less than 30 days) mortality was 7% in the MVR and 16% in the MVR + CABG group, with cardiac failure as the dominant cause. In multivariate analysis, the variables most strongly related to early mortality were congestive heart failure, diabetes and previous cardiac surgery in the MVR group and congestive heart failure in MVR + CABG. In the cases with fatal outcome the incidence of peroperative technical complications was 32% at MVR and 17% at MVR + CABG. The incidence of myocardial injury was 21% and 35% in the respective groups, and the early mortality in these cases was 19% vs 23%. Half of all fatal cases showed signs of peroperative myocardial injury. Multivariate analysis showed factors independently related to myocardial injury to be year of surgery and aortic cross-clamp time in MVR and previous cardiac surgery in MVR + CABG. Operation before cardiac reserves are reduced, optimal peroperative myocardial preservation and avoidance of technical errors should improve results of MVR. |
