Coronary Sinus Retroperfusion Combined with Intraaortic Balloon Pumping to Perfuse the Acutely Ischemic Myocardium

Abstract

This study was planned to show th e effect of retroperfusion and intraaortic ba lloon pumping (lABP) on myocardial hem odynamic recovery. Twelve dogs ente re d thi s study. Half ofthem received IABP and coro na ry sin us retr operfusion (CSPR) combination (Group II) a nd the remaining received IABP alone (Group I). Left a nte rior descending artery was occluded for a peri od of three hours. 15 min utes aft er occlusio n IABP and IABP + CSRP wer e initia ted. The aver age ca rdiac output was 1.41 ±0.18 Ll min in th e gro up I and 1.72± 0 .24 Umin in the gr oup II (p < 0.03) after 3 hours of occlusio n. Mean a rte rial pr essure was 82.1 ± 4.8 mmHg in th e group I and 89 .7 ± 2.6 mmHg in th e gro up II (p < 0.03). On th e basis of this stu dy it was conclud ed that CSRP + IABP could be an alt ernative treatment to IABP alone during the acutely developing ischemia.

Coronary Sinus Retroperfusion with a Simple Method

“…Certain additional factors may increase the efficiency of this method. [4][5][6][7][8] As a result of these findings, we recommend this technique especially in patients with a severe left anterior descending coronary artery lesion and poorly developed collateral circulation, critical left main stenosis, or acute coronary artery occlusion during surgery.…”
