Introduction

Welcome to the tricuspid stenosis page. On this page we provide a definition, sample heart sounds and links to the training lessons available on this site.

What is Tricuspid Stenosis?

Tricuspid stenosis, or tricuspid valve stenosis, is a heart disease with narrowing of the valve’s opening. The disease is most often caused by rheumatic fever, which is rare in North America.

Diagnosis

Tricuspid stenosis diagnosis includes auscultation (see below), echocardiography and heart catheterization.

Tricuspid Stenosis Heart Sounds Auscultation

This is an example of moderate tricuspid stenosis which is most commonly due to rheumatic heart disease. The first heart sound is increased in intensity due to moderate thickening of the the tricuspid valve leaflets. The second heart sound is normal and unsplit Systole is silent. There is a tricuspid opening snap followed by a diamond shaped low frequency murmur. Use the bell of the stethoscope to hear this murmur. There is a second murmur in late diastole due to contraction of the right atrium.
