Abstract
An 8-month-old boy with acute myocarditis was mechanically supported with the Berlin Heart EXCOR biventricular assist device. Signs of myocardial recovery were not apparent until 40 days from presentation and ventricular function continued to improve with device removal possible after 120 days of support. He had normal cardiac function 3 months after device removal. Recovery from myocarditis in infants can take much longer than previously recognized and an extended wait for recovery is possible with the Berlin Heart.
