May support biplane angiocardiography for LV stroke volume in select patients; leaves open validation in broader populations.
Does biplane angiocardiography accurately determine left ventricular stroke volume compared to Fick and/or indicator-dilution methods in subjects without arrhythmias or valvular insufficiency?
Biplane angiocardiography provides a reliable method for directly determining left ventricular stroke volume, showing close agreement with established Fick and indicator-dilution methods.
