Percutaneous intra-aortic balloon counterpulsation.

Intra-aortic balloon pumping is the mainstay in the management of acute left ventricular dysfunction in the critical care setting. Percutaneous insertion affords rapid initiation of the procedure. Complications are in greatest part vascular and infectious. The advent of new-generation, totally automatic, closed-loop IABP systems offers the prospect of increasing the effectiveness of IABP support under most conditions, and especially during arrhythmias. This and other developments suggest that despite its standing as the most widely used temporary cardiac assist device, IABP has still to realize its full therapeutic potential.
