Coronary blood flow alternans: A unique examination of coronary physiology and influence of intraaortic balloon pumping

Intraoperative bypass graft flow in intra-aortic balloon pump–supported patients: Differences in arterial and venous sequential conduits

“…1 The literature supports the former hypothesis, but the data on coronary (or possibly collateral) blood flow enhancement are inconsistent. 7,[12][13][14] Yoshitani and coworkers 7 recently reported a reduction in oxygen demand through decreased afterload, but no augmentation of diastolic coronary flow, by measuring intracoronary pressure distal to coronary stenosis in humans. Moreover, few data exist on the effects of IABP on flow within bypass grafts, most of which have been obtained from animal models.…”
