Inadvertent left ventricular placement of ICD lead through the left subclavian artery right positioned in a patient with situs viscerum inversus and Kartagener syndrome.

Inadvertent placement of pacemaker and implantable cardioverter-defibrillator (ICD) leads in the left ventricle is a rare but well-recognized complication of device implantation. We report a case of an unicameral ICD lead inadvertently placed through the left subclavian artery right positioned, across the aortic valve into the left ventricle, in a patient with situs viscerum inversus. A transthoracic echocardiogram about a month after the procedure showed an unusual course of the lead. The lead was successfully removed without complications or sequelae.
