Overview
Transthoracic echocardiography (TTE) is usually adequate for the evaluation of tricuspid regurgitation; to confirm the diagnosis, determine the etiology, establish the baseline severity and for the assessment of the function of the right ventricle prior to surgery. In cases of non-diagnostic transthoracic studies, transesophageal echocardiography (TEE) improves the visualization of the valvular structure and delineates the mechanism and severity of regurgitation.
Echocardiography
Echocardiography with doppler is the method of choice for the non-invasive detection and evaluation of the severity and etiology of valvular regurgitation. [1][2]Echocardiography allows the evaluation of the following:[3][4][5][6][7][8]
- Right ventricle structure and function
- Right atrium structure and function
- Inferior vena cava
- The structure and function of the left chambers of the heart
- The structures of the tricuspid valve and the underlying etiology of mitral regurgitation
- Pulmonary artery pressure
- Pressures in the heart chambers
- The severity of the tricuspid regurgitation through the measurement of:
- The tricuspid annular diameter in the apical 4-chamber view
- Tricuspid valve leaflet tethering height
- Tricuspid valve leaflet tethering area
- Tricuspid regurgitation jet velocity signal
- Characteristic primary valvular abnormalities can be detected by tricuspid valve motion which includes the conditions like:[9][10]
- Ebstein's anomaly
- Carcinoid heart disease
- Rheumatic valve disease
- Tricuspid valve prolapse
- Flail leaflet
- Endocarditis
- By using the vena contracta method with colour doppler we can estimate the severity of the tricuspid regurgitation and that includes:
- The vena contracta width has to be more than 0.7 cm along with systolic flow reversal in the hepatic veins
- In the presence of atrial fibrillation, systolic flow reversal in the hepatic veins cannot be accurate
- By using the modified Bernoulli equation, we can estimate pulmonary hypertension on echocardiography by measuring the right ventricle to right atrial systolic gradient from the velocity of the tricuspid regurgitation jet


Grading severity of TR
While Transthoracic Echocardiography (TTE) remains the first-line modality, its results are dependent on acoustic windows and operator expertise, which can lead to the underestimation of TR severity.[12] To address consistent underestimation, the 2025 European guidelines have adopted specific cutoffs for 3D vena contracta area (≥75 mm2) and proximal isovelocity surface area (≥75 mm2).[12][13] Comprehensive assessment must include 3D color Doppler to measure the vena contracta area without geometric assumptions, though high-resolution image acquisition remains a challenge.[14] Severity grading has been expanded to a 5-grade scale—including 'massive' and 'torrential' beyond the 'severe' category—which has shown significant prognostic importance for both medical and transcatheter therapies.[15] Transesophageal echocardiography (TEE), specifically 3D TEE, is essential for enhanced valve visualization and provides critical guidance during transcatheter tricuspid valve interventions (TTVI).[16] Assessment of TR severity should ideally be performed when the patient is in a euvolemic state, as the severity can fluctuate significantly based on cardiac loading conditions.[17] Intraprocedural monitoring often utilizes 3D intracardiac echocardiography to supplement TEE, particularly to confirm successful leaflet grasping during edge-to-edge repair procedures.[18][19]

Recommendations for Diagnosis of TR
| Class I |
| 1. In patients with TR, TTE is indicated to evaluate the presence and severity of TR, determine the etiology, measure the sizes of the right-sided chambers and inferior vena cava, assess RV systolic function, estimate pulmonary artery systolic pressure, and characterize any associated left-sided heart disease. (Level of Evidence: C-LD)" |
