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