IntroductionChronic elevation of left heart filling pressure causes pulmonary vascular remodeling, pulmonary hypertension, and right heart dysfunction. Although diastolic dysfunction is relatively common in patients with coarctation of aorta (COA), there are limited data about the prevalence and prognostic implications of pulmonary hypertension and right heart dysfunction in this population. The purpose of the study was to assess right heart function and hemodynamics in patients with COA, and to determine the relationship between right heart indices and clinical outcomes. MethodsRight heart structure, function and hemodynamics were assessed with these indicesright atrial (RA) volume, RA pressure, RA reservoir strain, right ventricular (RV) global longitudinal strain, RV end-diastolic area, RV systolic pressure, and tricuspid regurgitation severity. These indices were used to generate a composite right heart hemodynamic score (RHHS), range 0-5. We then assessed the relationship between RHHS and primary outcome (death/transplant) and secondary outcomes (heart failure hospitalization and hepatorenal function). ResultsOf 821 COA patients, RA dysfunction, RV dysfunction, and pulmonary hypertension were present in 16%, 14%, and 20% of patients respectively. RHHS was independently associated with primary and secondary outcomes (p
