Abstract
Intraaortic balloon pumping (IABP) has now evolved as the mechanical supportive treatment of choice for the management of refractory left ventricular power failure. A new single-chambered percutaneous intraaortic balloon (Datascope Corp., Paramus, NJ, U.S.A.) has been constructed around a central guidewire. The balloon can be wrapped around the guidewire, enabling its insertion into the femoral artery through a 12-F sheath, inserted by a modified Seldinger technique. A dual-lumen automatic wrapping version has recently been employed. Percutaneous IABP insertion has been performed in 149 patients (mean age 58 years). In our medical group of 75 patients, 59 underwent urgent open heart surgery and 53 (90%) survived. In patients who could not be separated from cardiopulmonary bypass, 23 of 61 (38%) survived. Vascular complications occurred in 10% of the patients. Percutaneous balloon insertion permits the rapid institution of IABP support and broadens the medical and surgical applications of IABP.
