[Determinants of left ventricular function in aortic stenosis. Analysis based on pre and postoperative hemodynamic studies].

In 11 preoperative patients with aortic stenosis the isovolumic contractile indices Vpm and Vmax were normal (group N). In 8 patients with aortic stenosis these indices were depressed (group D). Peak systolic circumferential wall stress (afterload) did not differ in the two groups and showed a similar decrease after successful valve replacement. Left… CONTINUE READING
