Causes
- right ventricular infarction
- pulmonary hypertension e.g. COPD
- rheumatic heart disease
- infective endocarditis (especially intravenous drug users)
- Ebstein's anomaly
- carcinoid syndrome
Signs
- pan-systolic murmur
- prominent/giant V waves in JVP
- pulsatile hepatomegaly
- left parasternal heave - due to associated right ventricular hypertrophy
Investigations
- ECG: usually nonspecific; they may show all peaked p waves or incomplete right bundle-branch block
- Echocardiography: to detect and quantify tricuspid regurgitation and heart function
- Cardiac MR is used for evaluating right ventricular size and function.
- Cardiac catheterisation: may be required prior to surgery to assess for coronary artery disease.
