Abstract:
Left ventricular outflow tract (LVOT) obstruction is mostly caused by hypertrophic obstructive cardiomyopathy and subaortic stenosis. Rarely, malignancy can lead to dynamic LVOT obstruction and has only been sporadically documented. We present the first case of dynamic and/or nearly fixed LVOT obstruction caused by a cardiac myxoid spindle cell sarcoma.
