- W2408926750 abstract "This study compares the effect of pulsatile (Group C, Fib/P) and nonpulsatile (Group B, Fib/NP) coronary perfusion on myocardial performance during 2 hours of normothermic ventricular fibrillation. Group A (BH/NP), used as a base-line observation, consisted of 2 hours of nonpulsatile coronary perfusion in beating hearts. The assessment of ventricular performance included diastolic ventricular compliance, myocardial oxygen consumption and lactate extraction, regional myocardial blood flow, and histology. After 120 minutes of ventricular fibrillation, Group C showed normal ventricular diastolic compliance as compared to a 50 per cent decrease in Group B (p less than 0.01). Myocardial oxygen consumption was not significantly different from that in Group B. Because of a 70 per cent increase in oxygen extraction above Group B (p less than 0.05), total left ventricular myocardial blood flow was reduced (103 +/- 23 versus 260 +/- 36 ml. per 100 Gm. per minute, p less than 0.05) and had near-constant resistance. Lactate extraction was significantly greater and more stable as compared to Group B (9.28 +/- 1.33 versus 1.8 +/- 1.08, p less than 0.05). Left ventricular endocardial/epicardial flow ratio was greater in Group C (1.21 +/- 0.08 versus 1.06 +/- 0.06, p less than 0.05). Minimal subendocardial histologic changes were present as compared to the marked patchy subendocardial ischemic changes seen in Group B. The results demonstrate that the addition of pulsatile flow to coronary perfusion minimized the deleterious effects of prolonged ventricular fibrillation on myocardial performance." @default.
