Tricuspid Regurgitation

In a patient with edema, ascites, elevated jugular venous pressure, hepatic congestion, or recurrent right-sided heart-failure admissions, obtain transthoracic echocardiography with comprehensive 2-dimensional and Doppler assessment. The study should confirm TR severity and evaluate leaflet morphology, annular dimensions, right-atrial and right-ventricular enlargement, and right-ventricular systolic function. BMJBMJIsolated tricuspid regurgitation: outcomes and therapeutic interventions | Heart

Interpret severe TR as a systemic venous-congestion lesion: TR increases right-atrial pressure and reduces venous return, contributing to right-sided heart-failure physiology. Hepatic-vein systolic flow reversal identifies severe TR; leftward bowing of the interatrial septum supports elevated right-atrial pressure or volume overload.

Obtain renal and hepatic function tests when severe TR is suspected clinically or echocardiographically, particularly before valve intervention. Isolated severe tricuspid-valve surgery should be considered before advanced functional limitation and hepatic dysfunction develop, because late organ dysfunction and advanced right-ventricular remodeling narrow the therapeutic window.

Classify TR as primary (organic) when leaflet or subvalvular structural pathology is present, versus functional when valve leaflets are structurally normal but malcoaptation results from annular and right-ventricular dilation. Functional TR is the most common acquired form; rheumatic disease is the most common cause of organic tricuspid-valve disease in the cited surgical review.

For functional TR, determine whether the phenotype is predominantly ventricular-functional or atrial-functional. Right-ventricular dilation and dysfunction with annular dilation favor ventricular-functional TR, often in the setting of pulmonary hypertension or left-sided valvular disease. Predominant right-atrial and annular dilation in atrial fibrillation favors atrial-functional TR. This distinction informs whether correcting upstream left-sided disease, pulmonary vascular loading, rhythm-related atrial remodeling, or the valve lesion itself is the more plausible therapeutic lever.

Review all prior transvenous cardiac implantable electronic device procedures and interrogate lead course on echocardiography when a lead traverses the tricuspid valve. Lead-related TR affects an estimated 20% to 30% of cardiac implantable electronic devices; establish whether the lead is plausibly contributing to leaflet interference or whether TR is instead functional from chamber remodeling before choosing a valve procedure. acpjournalsacpjournalsComplications Associated With Transvenous Cardiac Implantable ...

Use symptom-directed medical management to control volume overload while completing structural evaluation. In severe atrial-functional TR, substantial volume overload can worsen right-atrial and right-ventricular distortion, annular dilation, leaflet tethering, and coaptation gaps; decongestion can therefore improve candidacy assessment for transcatheter edge-to-edge repair. jaccjaccManagement of Volume Overload in Severe Atrial-Functional Tricuspid Regurgitation: Improved Feasibility of Transcatheter Edge-to-Edge Repair | JACC: Case Reports

Do not allow symptomatic improvement after decongestion to defer evaluation indefinitely when severe TR persists with right-sided remodeling or organ-congestion features. Severe TR is associated with progressive right-heart failure, and late referral is linked to advanced volume overload and anatomy less amenable to repair.

For functional TR, reassess severity after treatment of relevant upstream disease, including left-sided valvular pathology or pulmonary hypertension, because functional TR arises from annular and right-ventricular dilation and may be reversible in some patients. NatureNatureEvidence-based surgical management of acquired tricuspid valve disease | Nature Reviews Cardiology

Consider surgery for isolated severe tricuspid-valve disease before severe functional limitation and hepatic dysfunction, particularly when the right ventricle is markedly enlarged and systolic function is impaired. Surgical risk has historically limited isolated procedures: reported in-hospital mortality for isolated TR surgery is 5% to 13%, and current practice has therefore concentrated surgery in selected candidates.

For symptomatic severe or greater TR in patients considered for transcatheter repair, evaluate leaflet grasping anatomy, tethering, coaptation gap, annular and chamber dilation, and interaction with any transvalvular lead. Advanced longstanding volume overload can enlarge coaptation gaps and leaflet tethering, making transcatheter edge-to-edge repair less feasible; optimize congestion before final screening when possible. jaccjaccManagement of Volume Overload in Severe Atrial-Functional Tricuspid Regurgitation: Improved Feasibility of Transcatheter Edge-to-Edge Repair | JACC: Case Reports

In the 572-patient randomized TRILUMINATE cohort, TriClip transcatheter edge-to-edge repair was superior to medical therapy for the hierarchical primary endpoint at 1 year (win ratio 1.8; 95% CI, 1.4-2.5), driven primarily by health-status improvement. At 12 months, freedom from all-cause mortality or tricuspid surgery was similar for device and control groups (90.6% versus 89.9%), and annualized heart-failure hospitalization rates were also similar in the full cohort (0.17 versus 0.20 events per patient-year). jaccjaccTricuspid Transcatheter Edge-to-Edge Repair for Severe Tricuspid Regurgitation: 1-Year Outcomes From the TRILUMINATE Randomized Cohort

Frame transcatheter edge-to-edge repair as a symptom- and function-oriented intervention with demonstrated improvement in TR reduction, Kansas City Cardiomyopathy Questionnaire score, and 6-minute walk distance at 1 year. In TRILUMINATE, 52.3% of device-treated patients achieved at least a 15-point improvement in health status; treatment selection should therefore prioritize symptomatic severe disease with appropriate anatomy rather than an expectation of proven short-term mortality benefit. jaccjaccTricuspid Transcatheter Edge-to-Edge Repair for Severe Tricuspid Regurgitation: 1-Year Outcomes From the TRILUMINATE Randomized Cohort

After medical optimization or valve intervention, reassess integrated TR severity with echocardiography, including vena contracta, Doppler jet characteristics, hepatic-vein flow, inferior vena cava findings, right-sided chamber size, and right-ventricular function. Hepatic-vein systolic reversal and a dense dagger-shaped continuous-wave Doppler signal remain useful markers of severe residual TR.

Track systemic venous-congestion consequences with renal and hepatic function testing, physical examination for edema or ascites, and functional status. Worsening congestion or progressive right-sided enlargement despite treatment should trigger repeat multidisciplinary review rather than serial medical escalation alone.

After transcatheter edge-to-edge repair, assess residual TR and patient-centered response using functional capacity and health status; the randomized trial demonstrated improvements in Kansas City Cardiomyopathy Questionnaire score and 6-minute walk distance at 1 year, making both appropriate outcome measures when evaluating clinical benefit. jaccjaccTricuspid Transcatheter Edge-to-Edge Repair for Severe Tricuspid Regurgitation: 1-Year Outcomes From the TRILUMINATE Randomized Cohort
