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

Figures

Figure 1.
Figure 1. Concurrent measurement at rest of left ventricular and aortic pressures on a gradation of 0 to 200 mm Hg demonstrating an absence of left ventricular outflow tract gradient.
Figure 2.
Figure 2. Concurrent measurement of left ventricular and aortic pressures after isoproterenol administration exhibiting evidence of 120 mm Hg gradient (blue oval at lower panel). Also, an intensified left ventricular-aortic gradient (red oval at lower panel) was noted after premature ventricular contraction (green oval at upper panel).
