Pulmonary Insufficiency: Advantage of Pulmonary Regurgitation Volume Versus Pulmonary Regurgitation Fraction in a Congenital Heart Disease Mixed Population.

摘要: OBJECTIVE The objective of this study was to compare the use pulmonary regurgitation volume (PRV) or indexed PRV (PRVi) with that fraction (PRF) in assessment patients (PR) undergoing cardiac magnetic resonance (CMR) imaging. MATERIALS AND METHODS CMR 176 PR were retrospectively evaluated. Their right ventricular diastolic (end-diastolic index [EDVi]) and systolic (end-systolic index) indexes, stroke volume, ejection obtained from cine sequences, whereas phase-contrast flow sequences analyzed obtain PRV, PRVi, PRF. Patients divided into subgroups, according underlying pathology severity. Correlations between PRF RV parameters studied through Spearman ρ, both main group subgroups. Follow-up examinations analyzed, correlations first examination data second calculated. RESULTS Tetralogy Fallot setting (98/179). Overall, EDVi strongly correlates (ρ=0.592, P<0.001) than (ρ=0.522, P<0.001), end-systolic (ρ=0.454, (ρ=0.406, P <0.001). As regards subgroup analysis, moderate severe patients, (P=0.043) (ρ=0.499, (ρ=0.317, P<0.001). (ρ=0.450, P=0.031), but not CONCLUSIONS Especially when assessing PR, PRVi may be better indicators dysfunction Moreover, a predictor worsening dilation.
