Tricuspid regurgitation murmur

Tricuspid regurgitation murmur


Tricuspid regurgitation presents with pansystolic murmur best heard at the lower left sternal border (tricuspid area). Disease may be congenital or caused by rheumatic fever, with a prominent pulmonary hypertension. It may also occur in ischemic heart disease, cor pulmonale or cardiomyopathy. It involves the widening of the tricuspid valve so that blood regurgitates into the right ventricular from the right atrium at atrial systole.

Thus is also called Austin Flint murmur
