Abstract
Increased understanding of the anatomical nuances of congenital heart defects, improved methods of myocardial preservation, and advances in surgical techniques have led to improved results and need for postoperative mechanical support in patients undergoing congenital heart surgery. However, there remains a small portion of patients with myocardial or pulmonary failure that can can be rescued by intelligent use of mechanical support. The most widely used form of mechanical support is extracorporeal membrane oxygenation (ECMO), which has been adapted for use in congenital heart patients as well as patients with respiratory failure. Recent reports have suggested that ventricular support devices may also be useful in this patient population. A promising new application of mechanical support is for rescue during cardiac arrest; surprisingly good results have been obtained in this obviously moribund group of patients. Future developments in mechanical support include more accurate identification of patients who will benefit from this therapy and technological advances that will provide greater biocompatibility and simplification of the support circuit.
