Tricuspid Regurgitation - Severe


Tricuspid regurgitation (TR) is insufficiency of the tricuspid valve causing blood flow from the right ventricle to the right atrium during systole. The most common cause is dilation of the right ventricle. Symptoms and signs are usually absent, but severe TR can cause neck pulsations, a holo systolic murmur, and right ventricular–induced heart failure or atrial fibrillation.  Now you can listen to an example of severe tricuspid regurgitation which is caused by degeneration of the tricuspid valve leaflets. You can hear that 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.
