Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Aim of the study is to investigate the prognostic value of right ventricular contractile reserve in patients with functional tricuspid regurgitation undergoing tricuspid valve repair or replacement.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic volume overload in patients with severe tricuspid regurgitation (TR) leads to right ventricular (RV) dilatation, fibrosis and eventually failure. RV dysfunction is an important determinant of mortality in patients undergoing tricuspid valve surgery.

Aim of the current study is to investigate the prognostic utility of right ventricular contractile reserve in patients with severe TR undergoing surgical or interventional tricuspid valve repair or tricuspid valve replacement.

RV contractile reserve will be assessed using semi-supine bicycle stress echocardiography.

Echocardiographic parameters are prone to altered loading conditions, such as volume overload. Load independent RV contractility can only be measured using invasive pressure-volume-loop (PVL) analysis. Therefore RV PVL analysis will be done using conductance catheter in a subset of patients who undergo right heart catheterization for clinical evaluation of pulmonary hypertension. Aim of this sub study is the validation of non-invasively derived RV contractile reserve with load independent markers of intrinsic RV contractility.
