Enlarged Image for Hypertrophic Cardiomyopathy

Echocardiographic still frames from the parasternal long-axis. The left images were obtained prior to surgical myectomy, while the right images were obtained after myectomy in the same patient. The bottom images are magnified views of the left ventricular outflow tract. Note the surgical "bite" from the septum and enlargement of the outflow tract. Ao = aortic root, LA = left atrium, LV = left ventricle.
