The use of extracorporeal membrane oxygenation in the treatment of fulminant myocarditis: Current progress and clinical outcomes.

Myocarditis is an inflammatory condition of the myocardium and is usually categorised as acute nonfulminant and acute fulminant myocarditis. Myocardial injury can result via viral infections, direct injury or immune responses. Fulminant myocarditis can be characterised by severe and sudden cardiac inflammation that may result from cardiogenic shock, ventricular arrhythmias or multi-organ system failure. Extracorporeal membrane oxygenation (ECMO), also known as extracorporeal life support, is an effective technique for patients with fulminant myocarditis, providing heart and lung support and adequate gas exchange or perfusion to sustain life. Essentially, ECMO pumps blood out of the body to an oxygenator that acts as an artificial lung, which adds oxygen to the blood and removes carbon dioxide. This report aims to review recent advances in ECMO and relate case studies of fulminant myocarditis patients. The types of ECMO, predictive factors for success, clinical studies and recent technological advances in the field will be discussed.
