Category Cardiology
William Dabney
William Cec. Dabney (1849–1894) described epidemic chest pain (“Devil’s Grip”) and championed medical education, licensure, and public health in Virginia
Barlow syndrome
Barlow syndrome (primary billowing mitral leaflet syndrome (BMLS)). Auscultatory findings of late systolic murmur with non-ejection ('mid-late') systolic click
Hoffman-Rigler sign
Radiographic sign of left ventricular enlargement on lateral chest X-ray, based on LV extension behind the IVC; described by Hoffman and Rigler in 1965
John Barlow
John Brereton Barlow (1924-2008) was a South African cardiologist. Barlow described mitral valve prolapse (eponymously known as Barlow’s syndrome) in 1963
