Study of the Impact of Cardiac Output, Left Ventricular dP/dt and Temperature

LE were hyperrnobile and all but 2 were located at the leaflet coaptation point. All mitra l LE prolapsed 1nto the atrium during systole and the aortic LE prolapsed into the outflow tract during diastole. No LE were noted on the tricusp1d and pulmonic valves. No subject had a cardioembolic event during Jongterm lollow up. Conclusions: 1) LE are common (14%) in subjects with normal hearts. 2) LE are seen with equal frequency on the mitral and aortic valves; 3) LE persist unchar1ged over time; and more important 4) LE may not be a substrate for card•oembolism.
