    Abstract Background: Increased ventricular end‐diastolic pressure (VEDP) is a known risk fac‐ tor for morbidity and mortality in patients with single right ventricle (RV) physiology. Previous studies have shown mixed results correlating echocardiographic measure‐ ments with catheter‐derived VEDP in this population. Goal of this study was to eval‐ uate if echocardiographic systolic/diastolic ratio (S/D) correlated with VEDP.
    Methods: Patients with single RV physiology who underwent simultaneous echocar‐ diography and catheterization were evaluated. Systolic and diastolic durations were measured using tricuspid inflow durations from Doppler analysis to calculate the S/D ratio. VEDP was obtained from the catheterization report.
