Overview
Trans-thoracic echocardiography findings include thickening and retraction of immobile tricuspid valve leaflets with associated tricuspid regurgitation and immobility of the pulmonary valve cusps. Trans-esophageal echoardiography findings provide incremental assessment of the degree of cardiac valve involvement and the atrial septal anatomy in patients with carcinoid heart disease.
Echocardiography
Transthoracic echocardiography
- It is the gold standard for diagnosis and follow-up of carcinoid heart disease.[1]
- Should be performed in all patients with carcinoid syndrome and high suspicion of carcinoid heart disease such as clinical features or raised NT-proBNP and/or 5-HIAA levels.
- Findings includes followings:
- Thickening and retraction of immobile tricuspid valve leaflets with associated tricuspid regurgitation, which is severe at the time of identification in 90 percent of patients.
- Immobility of the pulmonary valve cusps.
Transesophageal echocardiography
- TEE is primarily used intraoperatively to image the patient with carcinoid heart disease during valve replacement surgery.
- TEE may provide incremental assessment of the degree of cardiac valve involvement and the atrial septal anatomy in patients with carcinoid heart disease.
Cardiac magnetic resonance
- It can be used to evaluate the pulmonary valve, identify cardiac metastases, and assess right ventricular size and function.[2]
