Both cardiovascular magnetic resonance (CMR) and 3D transthoracic echocardiography (3DE) can quantify right ventricular (RV) end diastolic volume (EDV) and ejection fraction (EF) accurately. This study was designed to estimate sample sizes and imaging costs to detect changes in RV EDV and EF using 3DE and CMR for future pulmonary arterial hypertension (PAH) drug trials.Same day CMR and 3DE were performed...
Left ventricular (LV) volumes obtained from RT3DE datasets are underestimated compared to cardiac magnetic resonance (CMR). We sought to study the accuracy and reproducibility of this technique in a multicenter setting, the inter-institutional differences in these variables in relationship with investigatorspsila experience, and the potential sources of underestimation. 92 patients underwent CMR and...
