This study was designed to evaluate the efficacy of original percutaneous left heart bypass (left atrial-aortic bypass: AAB) on 5 patients (three with cardiac arrest, two with cardiogenic shock) with heart failure caused by acute myocardial infarction. First, the insertion procedure for the dehemaize tube into the left atrium was performed easily and safely under transesophageal echo monitoring. All patients had already been treated with intra-aortic balloon pumping (IABP) and percutaneous veno-arterial bypass (VAB), but without effect. Two of three patients with cardiac arrest were also treated with AAB, producing prompt hemodynamic improvement. One recovered secondary to this hemodynamic improvement. Two patients with cardiogenic shock were treated with AAB, and hemodynamics also improved. In particularly, a patient who had been dependent on IABP for 1 month, recovered from cardiogenic shock in response to AAB treatment within 3 days and subsequently underwent arteriocoronary bypass. In conclusion, VAB is useful for prompt treatment of cardiac arrest, while AAB is very useful for IABP and VAB is ineffective for heart failure.
