Bridging circulatory support before heart transplant without invasion of the mediastinum.
Heart transplantation is becoming a useful tool in the clinical treatment of patients with end-stage cardiac decompensation. Donor organs are not always available at a critical time for a patient waiting for a transplant. Bridging techniques have been described that use mechanical support systems. This article describes the use of femoral-venous to femoral-arterial bypass over a period of 50 hours in a 38-year-old woman waiting for a donor heart. Because the patient sustained cardiopulmonary arrest before organ availability, mechanical circulatory support that used femoral-venous to femoral-arterial bypass was instituted. The patient's own lungs were used as an oxygenator. Pump flow levels were determined by the level of central aortic oxygen saturation. Successful transplant was performed, and bridging, therefore, was done without invasion of the mediastinum.
