Spontaneous rupture of an intra-aortic balloon pump

Circulatory assistance with an intraaortic balloon pump is not free from risks and complications. Among the latter, rupture is extremely rare. We report a case of spontaneous rupture of an intraaortic balloon, which occurred after 29 h of counterpulsation in a patient with cardiogenic shock following an acute myocardial infarction. The probable cause of the rupture was the constant abrasion and eventual perforation of the balloon membrane by a sharp calcified aortic plaque.
