Haemodynamic findings in obstructive hypertrophic cardiomyopathy: pulsus bisferiens and Brockenbrough-Braunwald-Morrow sign.
: A 55-year-old gentleman with hypertrophic obstructive cardiomyopathy and heart failure symptoms underwent cardiac catheterization, which confirmed a significant pressure drop (60 mmHg) across the left ventricular outflow tract, a double-peaked pulse (pulsus bisferiens) and an absent postextrasystolic potentiation (Brockenbrough-Braunwald-Morrow sign) in the left ventricular outflow tract and ...
متن کاملEchocardiographic evidence of the Brockenbrough-Braunwald-Morrow sign after mitral valve repair.
The Brockenbrough–Braunwald–Morrow sign was first described in 1961 (1) in individuals with hypertrophic cardiomyopathy and dynamic left ventricular (LV) outflow tract (LVOT) obstruction worsened by conditions associated with increased myocardial contractility. The sign was characterized by an increase in peak-systolic gradient combined with a decrease in pulse pressure after an extrasystolic b...
متن کاملFifty Years of Cardiac Catheterisation in the Differential Diagnosis of Left Ventricular Outflow Tract Obstruction: the Brockenbrough-braunwald Sign
In February 1961, Brockenbrough, Braunwald and Morrow described a new haemodynamic test in the differential diagnosis of left ventricular outflow tract (LVOT) obstruction, based on the haemodynamic profiles of the left ventricle and aorta immediately following an extrasystolic beat. Despite 50 years of multiple technological advances, the observation retains a place in the discrimination of fix...
متن کاملPropranolol in management of muscular subaortic stenosis.
Muscular subaortic stenosis (Wigle, Heimbecker, and Gunton, 1962) is one of the names used to describe functional ventricular obstruction which simulates aortic valve stenosis. Other workers (Brock, 1957, 1959; Teare, 1958; Morrow and Braunwald, 1959; Brent et al., 1960; Brockenbrough, Braunwald, and Morrow, 1961; Goodwin et al., 1960) have also emphasized the functional nature of the myocardia...
متن کاملThe Contour of the Subvalvar Pressure Curve in Subaortic Stenosis.
In making the distinction between the muscular and discrete types of subvalvar aortic stenosis the assessment of the hemodynamic data is vital, but the criteria are unsatisfactory in a number of cases. Most reports dealing with the hamodynamic features (Brachfeld and Gorlin, 1959; Goodwin et al., 1960; Hancock, 1961; Boiteau and Allenstein, 1961; Brockenbrough, Braunwald, and Morrow, 1961; Boit...
