Complex Conditions: Tricuspid Regurgitation - Severe
Review the animation. Observe the enlarged right atrium and right ventricle. You can see the turbulent blood flow from the right ventricle into the right atrium. This is the systolic murmur. Notice the brief turbulent blood flow from the right atrium to the right ventricle in diastole. This is caused by too much blood in the right atrium which forces blood back into the ventricle during diastole producing the flow rumble. 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.
