A shock lead intentionally placed in the left ventricle.

The implantable cardioverter defibrillator is effective in reducing sudden cardiac death in high-risk patients. The implantation procedure is usually simple; however, in those patients who have congenital heart disease (CHD) placement of leads can be a challenge. In this report we present a patient with CHD where due to the complex cardiac anatomy it was decided to place the shock lead in the left ventricle.
