Transbrachial intra-aortic balloon pumping for a patient with fulminant myocarditis.

A 57-year-old man with acute myocarditis was transferred to our hospital from a local clinic. The patient experienced unexpected sudden cardiac arrest 16 h after admission. Mechanical cardiopulmonary support was started using percutaneous cardiopulmonary support, intra-aortic balloon pumping (IABP), continuous hemodialysis filtration, and temporary cardiac pacing with percutaneous cannulation of the femoral vessels. Hematoma developed at the IABP insertion site on the 5th day after admission. The IABP was removed, and another IABP system was inserted via the left brachial artery. The patient's condition improved, and the IABP was removed on the 9th day after admission. The remainder of the patient's in-hospital treatment was uneventful, and he showed near-normal left ventricular systolic function 1 year after discharge.
