Dual-chamber implantable cardioverter defibrillator implantation guided by non-fluoroscopic electro-anatomical navigation.

A dual-chamber implantable cardioverter defibrillator was implanted in a 37-year-old pregnant woman with dilated cardiomyopathy, symptomatic sinus bradycardia, and a family history of sudden death. Two leads were connected to a three-dimensional navigation system and placed at the right atrium and right ventricle, respectively, without fluoroscopy.
