[Anesthesia for cardiac resynchronization therapy in a child after cardiac surgery with dilated cardiomyopathy]

We report a case of anesthesia for cardiac resynchronization therapy (CRT) in a child with dilated cardiomyopathy who had undergone cardiac surgery for double outlet right ventricle. The patient was a 23-month-old boy, who had undergone pacing lead implantation as a part of CRT. His postoperative interventricular synchronization was improved significantly, and he was placed off mechanical ventilation at the early stage. However, heart failure developed slowly and his cardiac function deteriorated. Mechanical ventilation was required in consequence. We conclude that optimal time to initiate CRT as well as indications for CRT should be carefully examined.
