Study: NCT05081115

Intervention type: DIAGNOSTIC_TEST
Intervention: SE Right ventricular function assessment
Description: Right ventricular function will be assessed at baseline and peak stress with variations of tricuspid annular plane systolic excursion, an index of right ventricular longitudinal function, and right ventricular fractional area change (a load-dependent index of right ventricular inlet function). To distinguish between genuine right ventricular dysfunction and/or pathological increases in pulmonary vascular load, we will combine systolic pulmonary artery pressure and right ventricular end-systolic area to calculate right ventricular end-systolic pressure-area relation. Peak systolic tricuspid annulus velocity and conventional indices of left ventricular systolic and diastolic function will also be measured at baseline and peak stress according to the standard ABCDE-FGLPR protocol. Right ventricular free wall strain combined with interventricular septum strain will be assessed. Left ventricular function, wall motion score index and E/e' at baseline and peak stress.
