What is Tricuspid Regurgitation?

Tricuspid regurgitation is a condition wherein blood leaks backwards from the right ventricle into the right atrium. This may caused by a tricuspid valve not closing correctly, enlarged right ventricle and congenital heart disease.

Auscultation of Tricuspid Regurgitation

Tricuspid regurgitation diagnosis can begin with heart auscultation. Echocardiogram, EKG, heart catheterization, CT and MRI are other tests used in diagnosis.

Tricuspid Regurgitation Heart Sounds Recordings

This is a simulation of severe tricuspid regurgitation which is caused by degeneration of the tricuspid valve leaflets. The first heart sound is normal. The second heart sound is unsplit. There is a loud, rectangular, pansystolic murmur. There is a brief, rumbling, diamond-shaped diastolic murmur. To differentiate tricuspid regurgitation from mitral regurgitation, the maximum intensity of the tricuspid murmur is heard at the left lower sternal border. In addition, the murmur intensity increases with inspiration.

Systole: Loud, pan-systolic murmur, louder during inspiration.
Diastole: Brief, rumbling diamond shaped murmur may follow pan-systolic murmur in some cases.
