[Benefit of the autoperfusion balloon catheter for emergency coronary artery grafting after failed percutaneous transluminal coronary angioplasty].

A 61-year-old man was operated on an emergent basis because of abrupt closure of left anterior descending coronary artery (LAD) following failed coronary angioplasty. At once abrupt closure occurred, Stack autoperfusion balloon catheter was placed across the coronary lesion to reestablish blood flow to the ischemic myocardial area with intraaortic balloon counterpulsation. Despite a longtime of 12 hours to cardiopulmonary bypass, the patient had been managed with excellent resolution of symptoms and ST elevation. Under a stable hemodynamic state, saphenous vein grafting to LAD was performed with minimal myocardial infarction. Stack catheter made it possible to perform the subsequent coronary bypass operation as a controlled, optimal revascularization procedure because of its passive autoperfusion effect.
