What is the recommended treatment for mild tricuspid (tricuspid valve) regurgitation with mildly elevated right heart pressure?

Management of Mild Tricuspid Regurgitation with Mildly Elevated Right Heart Pressure

For mild tricuspid regurgitation with mildly elevated right heart pressure, medical management with diuretics for symptom control is the appropriate first-line approach, with no indication for surgical intervention at this stage. 1

Medical Management Strategy

Diuretic therapy is the cornerstone of treatment when right-sided heart failure symptoms or congestion are present, providing symptomatic relief without delaying consideration of intervention when it becomes indicated. 1

• Loop diuretics should be used to manage any signs of systemic or hepatic congestion. 2
• Aldosterone antagonists may provide additional benefit for volume management related to TR. 2
• Guideline-directed medical therapy for heart failure should be optimized if left ventricular dysfunction coexists. 2

Surgical Intervention is NOT Indicated

Current guidelines do not recommend surgical intervention for mild TR, even with mild annular dilation or mildly elevated right heart pressures. 1

• Surgery is specifically not recommended in patients with tricuspid annular dilatation but absent or only trace amounts of TR. 1
• Isolated tricuspid valve surgery is reserved for severe primary TR with symptoms or progressive right ventricular dysfunction. 1

Critical Monitoring Parameters

Regular echocardiographic surveillance is essential to detect progression that would change management:

• Tricuspid annular diameter: Progression to ≥40 mm (or ≥21 mm/m²) becomes relevant only if left-sided cardiac surgery is planned. 1, 2
• Right ventricular function: Monitor TAPSE (normal >17 mm) and RV free wall longitudinal strain to detect early dysfunction. 1, 2
• TR severity progression: Advancement to moderate or severe TR (vena contracta ≥7 mm, EROA ≥0.4 cm²) would trigger reassessment. 2
• Pulmonary artery pressure: Development of significant pulmonary hypertension (PASP >35-40 mmHg) changes the clinical picture. 2

When Intervention Would Become Appropriate

Surgical consideration would only arise in specific scenarios:

• If undergoing left-sided valve surgery and TR has progressed to moderate severity with annular dilation ≥40 mm, concomitant tricuspid repair should be considered (Class IIa recommendation). 1, 2
• If TR progresses to severe with symptoms of right heart failure unresponsive to medical therapy, or with progressive RV dilation/dysfunction despite medical management. 1, 2
• If atrial fibrillation develops with progressive RV dysfunction/dilation despite guideline-directed medical therapy, tricuspid repair may be considered (Class IIb). 1

Common Pitfalls to Avoid

• Do not pursue surgical intervention for mild TR alone, regardless of mildly elevated right heart pressures, as this does not meet criteria for intervention and surgery carries significant risk without proven benefit at this stage. 1
• Avoid delaying medical optimization while waiting for progression—optimize volume status and treat underlying causes of elevated right heart pressure now. 2
• Do not ignore underlying left-sided heart disease or pulmonary hypertension, as secondary TR is most commonly caused by these conditions and treating the underlying cause is paramount. 3, 4
