Prognostic value of right ventricular-pulmonary arterial coupling in adults with repaired coarctation of aorta.

ABSTRACT:

Background

Right ventricular (RV) systolic dysfunction and pulmonary hypertension is present in 20 % of adults with repaired coarctation of aorta (COA). However, the prognostic value of RV to pulmonary artery (RV-PA) coupling in this population is unknown. The purpose of this study was to assess the relationship between RV-PA coupling and clinical outcomes (heart failure hospitalization and all-cause mortality) in this population.

Methods

Retrospective cohort study of adults with repaired COA and normal RV systolic function defined as RV free wall strain ≥ -24 %. RV-PA coupling was assessed using tricuspid annular plane systolic excursion/RV systolic pressure (TAPSE/RVSP) ratio.

Results

Of 509 patients (median age 32 [20-45] years; men 290 [57 %]), the average TAPSE a
