Abstract

Left ventricular outflow tract obstruction with a systolic anterior motion of the mitral valve is a challenging pathology. An intervention, either surgically or with a percutaneous technique is taken into consideration when the pressure gradient reaches critical levels. Subaortic myectomy is still the gold standard treatment modality in these particular patients. Modified Konno procedure may be added to the procedure when a significant gradient persists following subaortic resection, because of its association with increased outflow tract obstruction relief.
We herein present our experiences with two cases that underwent modified Konno procedures for the treatment of hypertrophic obstructive cardiomyopathy.
