A 73 year old man presented with angina and nonsustained ventricular tachycardia. Cardiac catheterization revealed the dynamic systolic intracavitary gradient of hypertrophic obstructive cardiomyopathy. Abnormal isovolumetric relaxation resulted in the development of a diastolic gradient from the left ventricular outflow tract to the left ventricular apex accompanied by intracavitary regurgitation of contrast material from the outflow tract to the left ventricular body during left ventriculography. This case provides hemodynamic and angiographic confirmation of abnormal isovolumetric relaxation in this syndrome and insight into its mechanism.
