[Anesthetic management for cardioverter defibrillator implantation in a patient with preoperatively undiagnosed myotonic dystrophy].
We unexpectedly anesthetized a 31-year-old male with mild myotonic dystrophy (MD) that had not been diagnosed preoperatively, for implantable cardioverter defibrillator (ICD) implantation. Although MD is an uncommon disorder, cardiac conduction abnormalities and dilated cardiomyopathy are seen commonly in these patients. Therefore, chances of ICD implantation may increase in MD patients. But, the patients are often unaware of this disease and it is common for them to conceal their symptoms, and the diagnosis may not be made before the operation. We emphasize that preoperative assessment is important and that it is necessary to consider MD in patients for ICD implantation.
