- Abstract
Abstract: Objectives: To assess left ventricular myocardial mechanics in a patient with acute severe aortic regurgitation. Methods: Left ventricular strain was derived from two-dimensional echocardiographic data. Results: There is marked decrease in longitudinal and radial strain at the left ventricular base with mild reduction at the apex. Circumferential strain and rotation were mildly reduced basally and preserved apically with normal torsion. Conclusions: Our findings reflect elevated wall stress, mostly at the left ventricular base, and at the longitudinal, predominantly subendocardial fibers. The apex and the circumferential midwall fibers where wall stress is lower are less affected. To our knowledge, this is the first description of left ventricular mechanics by strain imaging in acute aortic regurgitation.
