Key result
Left heart bypass significantly reduced left ventricular end-diastolic pressure and increased endocardial flow compared to intraaortic balloon pumping in a swine model of cardiogenic shock.

Animal data suggest left heart bypass may enhance endocardial flow over IABP; leaves open clinical translation in cardiogenic shock.
Does left heart bypass improve coronary microcirculation compared to intraaortic balloon pumping in a swine model of cardiogenic shock?
Left heart bypass is more effective than intraaortic balloon pumping for improving myocardial microcirculation in a swine model of cardiogenic shock.
Hata et al. (1996) studied Cardiogenic shock. Left heart bypass (LHB) vs. Intraaortic balloon pumping (IABP) was evaluated on Coronary microcirculation (epicardial flow, endocardial flow, LVEDP). Left heart bypass significantly reduced left ventricular end-diastolic pressure and increased endocardial flow compared to intraaortic balloon pumping in a swine model of cardiogenic shock.
