Why the study?
Does single beam echocardiography accurately estimate left atrial and ventricular volumes compared to cineangiography?
Does single beam echocardiography accurately estimate left atrial and ventricular volumes compared to cineangiography?
Single beam echocardiography provides a reliable, non-invasive estimation of left atrial and ventricular volumes that correlates well with invasive cineangiography.
