The prognostic value of the Dandel's index in patients undergoing tricuspid transcatheter edge-to-edge repair.

ABSTRACT:

Aims

Conventional parameters of right ventricular (RV) function are load-dependent and therefore do not accurately reflect contractility in patients with relevant tricuspid regurgitation (TR). RV adaptability to load has been characterized using the Dandel's index in patients with heart failure, but its prognostic value in patients undergoing tricuspid transcatheter edge-to-edge repair (T-TEER) has not been investigated so far.

Methods and results

From the EuroTR registry (2019 to 2022), patients with complete datasets and a minimum of 2-years of follow-up were included. RV functional parameters (i.e. tricuspid annular plane systolic excursion [TAPSE], fractional area change [FAC], TAPSE/systolic pulmonary arterial pressure [sPAP]), as well as a echocardiographic RV load ada
