Regional dyssynergy of the interventricular septum after septal artery occlusion in hypertrophic obstructive cardiomyopathy: use of quantitative Doppler tissue and strain rate imaging

J Am Soc Echocardiogr. 2004 Apr;17(4):384-6. doi: 10.1016/j.echo.2003.11.005.

Abstract

We report the regional myocardial mechanics of the interventricular septum in a patient with hypertrophic obstructive cardiomyopathy undergoing therapeutic septal artery occlusion. Myocardial velocities improved across the entire septum; however, strain rate imaging showed the presence of severe regional dyssynergy.
