Dynamic left ventricular outflow obstruction after aortic valve replacement: a Doppler echocardiographic study.
An 81-year-old woman with severe symptomatic aortic stenosis underwent aortic valve replacement. The postoperative course was complicated by new subvalvular left ventricular outflow tract obstruction created by systolic anterior motion of the anterior mitral leaflet. The condition was recognized by echocardiography and was successfully treated medically.
