Fifty Years of Cardiac Catheterisation in the Differential Diagnosis of Left Ventricular Outflow Tract Obstruction: the Brockenbrough-braunwald Sign
نویسندگان
چکیده
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 fixed versus dynamic LVOT obstruction.

: 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 ...

Data concerning 17 consecutive patients with discrete subaortic stenosis are recorded. Twelve patients underwent operative resection of the obstructing lesion. Of these all except one were symptomatic and all had electrocardiographic evidence of left ventricular hypertrophy or left ventricular hypertrophy with strain. They had a peak resting systolic left ventricular outflow tract gradient of g...

A 79-year-old white woman with known hypertrophic obstructive cardiomyopathy (HOCM) presented with sudden-onset chest pain and no identifiable stressor. Examination suggested a new apical 3/6 systolic murmur and pulmonary edema. A 12-lead electrocardiogram showed anterolateral wall ischemia. The patient’s peak troponin T level was 2.5 ng/mL. Echocardiography revealed a basal hypertrophied septu...

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 کاملHaemodynamic Alterations Induced by Isoprenaline in Patients with Obstruction to Right Ventricular Outflow.
It is now well established that there are two fundamentally distinct types of obstruction to left ventricular outflow, the first resulting from a discrete, fixed narrowing at a valvular, supravalvular, or subvalvular level, and the second being produced by muscular hypertrophy in the left ventricular outflow tract. A number of designations, including obstructive cardiomyopathy (Goodwin et al., ...
