The mean preoperative characteristics included EF, 27\u00b16%; aortic valve mean gradient, 44\u00b118 mm\u2009Hg; aortic valve area, 0.6\u00b10.2 cm<jats:sup>2<\/jats:sup>; and cardiac output, 4.1\u00b11.5 L\/min. Simultaneous coronary artery bypass graft surgery was performed in 78 patients (51%). Perioperative (30-day) mortality was 9% (14 of 154 patients). Fifty patients died during follow-up. Coronary artery disease (<jats:italic>P<\/jats:italic>=.002) and a reduced preoperative cardiac output (<jats:italic>P<\/jats:italic>=.03) were significantly related to reduced overall survival rate by multivariate analysis. Postoperative improvement occurred in most patients; 88% were New York Heart Association class III or IV before surgery versus 7% after surgery. Postoperative EF was assessed in 76% of survivors; 76% of these demonstrated improvement. By multivariate analysis, change in EF was inversely related to coronary disease (<jats:italic>P<\/jats:italic>=.002) and preoperative aortic valve area (<jats:italic>P<\/jats:italic>=.03).<\/jats:p><jats:p><jats:italic>Conclusions<\/jats:italic>Despite LV dysfunction, the risk of aortic valve replacement for AS was acceptable and related to coronary artery disease and mean aortic gradient, and long-term survival was related to coronary disease and cardiac output.
