Supports 3D echocardiography for LV assessment in pulmonary hypertension; leaves open prospective outcome validation before wider adoption.
Does quantitative three dimensional echocardiography accurately estimate left ventricular volumes and ejection fraction compared to MRI in patients with pulmonary hypertension and compressed left ventricles?
Three-dimensional echocardiography provides reliable estimates of left ventricular volumes and ejection fraction without geometric assumptions in patients with deformed left ventricles due to pulmonary hypertension.
