Brockenbrough-Braunwald-Morrow Sign: An Evaluative Hemodynamic Maneuver for Left Ventricular Outflow Tract Obstruction

A case of a 77-year-old woman with a history of hypertrophic cardiomyopathy (HCM) presented with intermittent episodes of exertional dyspnea and chest discomfort. Her coronary angiogram revealed normal coronary arteries but with hypertrophic obstructive cardiomyopathy with an increasing left ventric...

description A case of a 77-year-old woman with a history of hypertrophic cardiomyopathy (HCM) presented with intermittent episodes of exertional dyspnea and chest discomfort. Her coronary angiogram revealed normal coronary arteries but with hypertrophic obstructive cardiomyopathy with an increasing left ventricular-aortic gradient on isoproterenol provocation. Likewise, an intensified gradient was observed after a premature ventricular contraction (PVC) that is distinguished as the Brockenbrough-Braunwald-Morrow sign substantiating confirmation of left ventricular outflow tract (LVOT) obstruction.
