We report 93 cases of severe aortic stenosis. We discuss their clinical data, hemodynamic parameters, and surgical outcome. The surgical mortality and variables determining this event evaluated in groups: A (deaths) and B (survivors). Functional class (mean = 2.5 vs 2.0 p less than 0.05) was statistically as determinant for mortality as were also: transaortic gradient (group A mean = 110 +/- 37 mmHg vs group B mean = 82 +/- 31 p less than 0.005), and ejection fraction (group A mean = 55 +/- 13… CONTINUE READING
