[Initial experience with the Impella left ventricular assist device for postcardiotomy cardiogenic shock and unprotected left coronary artery angioplasty in patients with a low left ventricular ejection fraction].
Low-output syndrome is one of the leading causes of death following open-heart surgery or high-risk angioplasty. Ventricular assist devices have been used to treat patients who suffer from postoperative cardiogenic shock despite use of an intraaortic balloon pump and maximum inotropic support. The Impella pump (Impella Cardiosystems AG, Aachen, Germany) is a newly introduced left ventricular assist device that has been shown to reduce infarct size and to accelerate recovery of stunned myocardium. We report our initial experience using the Impella device for the treatment of cardiogenic shock following cardiopulmonary bypass and for maintaining hemodynamic stability in high-surgical-risk patients undergoing unprotected left coronary artery angioplasty.
