Coronary venous retroperfusion of arterial blood for the treatment of acute myocardial ischemia (original) (raw)

Catheterization and cardiovascular diagnosis, 1993

Abstract

Synchronized coronary venous retroperfusion of autologous arterial blood was offered to patients referred for medically refractory unstable angina or evolving myocardial infarction with contraindications to thrombolytic therapy. Primary endpoints of angina, ST segment deviation, and two-dimensional echocardiographic systolic wall motion were followed to determine the efficacy of retroperfusion in patients prior to and then during angioplasty, surgical intervention, or pharmacological management, as the clinical picture warranted. Over a 12 month period, 21 patients were referred and 15 received retroperfusion. All experienced full relief of angina (p = 0.008). ST segment deviations and systolic wall motion of ischemic zones were observed to improve (p = 0.06 ST changes; p = 0.0001 wall motion changes) with synchronized retrograde perfusion. During attempts to remove patients from retroperfusion, statistically significant (p < 0.01) reproducible changes in these same endpoints wer...
