Abstract
Treatment of patients with coronary artery disease with severe left ventricular dysfunction (EF less than 25%) presents a special challenge to the health care team. The ability to revascularize coronary artery lesions using percutaneous transluminal coronary angioplasty is limited because of the risk of acute vessel closure, which can result in hemodynamic collapse, myocardial infarction, and the need for emergent coronary bypass surgery. These patients may not survive long enough to undergo emergency open-heart surgery if acute vessel closure occurs. Percutaneous cardiopulmonary support (PCPS), initiated in the catheterization laboratory before coronary revascularization, can provide the hemodynamic support needed to allow the patient to tolerate the high-risk procedure. This article describes the PCPS procedure at Washington Adventist Hospital, Takoma Park, MD, and includes the clinical applications, risks and benefits, and implications for the critical care nurse.
