Overview
Tricuspid regurgitation causes systolic regurgitation from the right ventricle into the right atrium.
Functional tricuspid regurgitation commonly occurs secondary to right ventricular or right atrial dilation.
Clinical Features
Symptoms may reflect systemic venous congestion, including peripheral edema, ascites, hepatomegaly, and fatigue.
A pansystolic murmur is typically heard along the lower left sternal border and may increase with inspiration.
Inspiration classically accentuates right-sided murmurs.
Investigation
Echocardiography assesses valve structure, regurgitation severity, right ventricular function, and pulmonary pressures.
Management
Management focuses on treating the underlying cause and controlling systemic venous congestion. Severe disease may require surgical or transcatheter intervention.
Clinical Pearls
Right-sided murmurs often increase with inspiration.
