Abstract
A patient with severe aortic regurgitation due to rapidly progressive staphylococcal endocarditis demonstrated an unusual physical sign of prominent diastolic venous pulsation. We suggest that this venous pulse is the result of diastolic ventricular interaction in which inflow of blood into the right ventricle is arrested in the latter part of diastole due to extreme left ventricular distension. We wish to highlight this sign so that others can look for it with the aim of improving our understanding and treatment of ventricular interaction associated with heart failure.
