Effect of Coronary Artery Embolization on Ventricular Volumes.

• The measurement of ventricular volume enhances the ability to appraise ventricular performance. The development of the thermodilutdon method for estimating stroke volume (SV), end systolic volume (ESV), and end diastolic volume (EDV) allowed us to reexamine myocardial function at progressive degrees of ischemic injury produced by repeated embolizations of the coronary artery. We determined left ventricular SV, ESV, and EDV together with intraventricular pressures after embolizations by lycopodium spores injected into a branch of the left coronary artery.
