<1% of patients with moderate or greater TR are treated with surgery annually7
Treatment options
Tricuspid regurgitation (TR) treatment options have been limited with mixed outcomes.1,2
Based on the 2021 European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) Guidelines for the management of valvular hear disease:2
- Medical therapy focuses on volume control with diuretics
- Although data are limited, rhythm control may help to decrease TR and contain annular dilatation in patients with chronic atrial fibrillation (AF)
- Limited data suggest that rhythm control strategies in chronic AF may reduce TR and limit annular dilatation
- No Class I recommended medical therapy for symptomatic, severe TR
- Transcatheter tricuspid valve intervention (TTVI) may be considered for inoperable patients with severe, symptomatic secondary TR
Surgical intervention has high in-hospital mortality when patients present late, and unclear benefits compared with medical treatment.3,4
Medical therapy
There is currently no Class I recommended medical therapy for symptomatic, severe TR in the 2021 ESC/EACTS Guidelines. Medical treatment for TR is primarily focused on volume management with diuretics.2,5

Medical therapy alone shows little benefit in terms of long-term prognosis for patients with significant TR.*

Surgical intervention
The 2021 ESC/EACTS Guidelines recommendations for surgery on primary and secondary TR:2
2021 ESC/EACTS recommendations on primary TR | Class | Level |
Surgery is recommended in patients with severe primary TR undergoing left-sided valve surgery. | I | C |
Surgery is recommended in symptomatic patients with isolated severe primary TR without severe right ventricular (RV) dysfunction. | I | C |
Surgery should be considered in patients with moderate primary TR undergoing left-sided valve surgery. | IIa | C |
Surgery should be considered in asymptomatic or mildly symptomatic patients with isolated severe primary TR and RV dilatation who are appropriate for surgery. | IIa | C |
2021 ESC/EACTS recommendations on secondary TR | Class | Level |
Surgery is recommended in patients with severe secondary TR undergoing left-sided valve surgery. | I | B |
Surgery should be considered in patients with mild or moderate secondary TR with a dilated annulus (≥40 mm or >21 mm/m2 by 2D echocardiography) undergoing left-sided valve surgery. | IIa | B |
Surgery should be considered in patients with severe secondary TR (with or without previous left-sided surgery) who are symptomatic or have RV dilatation, in the absence of severe RV or left ventricle (LV) dysfunction and severe pulmonary vascular disease/hypertension.* | IIa | B |
*In patients with previous surgery, recurrent left-sided valve dysfunction needs to be excluded.
Surgical repair procedures for TR6
There are three distinct surgical techniques employed to address issues with the tricuspid valve.6
The De Vega annuloplasty involves placing a double row of sutures along the annulus of the anterior and posterior leaflets, effectively gathering the valve annulus to reduce its size. Bicuspidisation is a procedure where a suture is strategically placed along the annulus of the posterior leaflet, specifically reducing its size and creating a bicuspid valve configuration. In contrast, ring annuloplasty utilises a rigid or semirigid tricuspid valve ring of an appropriate size, which is then implanted at the annulus of the tricuspid valve to provide structural support and improve valve function.6
Late surgical correction of isolated secondary TR carries uncertain benefit over medical management and poses significant periprocedural risks.2
8.8% in-hospital mortality risk for isolated tricuspid valve surgery8
5.6% overall predicted risk of operative mortality for isolated tricuspid valve surgery9
Transcatheter techniques are now available to treat severe or greater TR
TTVI is an emerging treatment option for patients with severe or greater TR at high surgical risk. It is less invasive than surgery and aims to reduce symptoms and improve quality of life.10-13

Compared with surgery, TTVI may be a low-risk procedure we can offer to patients*

TTVI for the treatment of patients with severe, symptomatic TR has gained increasing attention in recent years.12-14
