RESUMO
A 75-year-old man, 8 years after CABG, with ischemic cardiomyopathy underwent cardiac resynchronization therapy (CRT) for refractory heart failure. Retrograde occlusion venography revealed absence of lateral vein. A functionally occluded middle cardiac vein with branch to anterolateral vein was used for left ventricular lead implantation. Using a collateral route for left ventricular lead implantation is a new technique. Lead position was stable with excellent threshold. Follow-up at 6 months reveals continued stable lead position.

Twiddler syndrome is a form of pacemaker lead dislocation caused by the coiling of the pacemaker leads due to pulse generator rotation on its long axis. Similar to Twiddler syndrome, Reel syndrome occurs due to rotation of the pulse generator on its transverse axis, leading to lead dislocation or fracture, followed by clinical symptoms of dislodged leads. We report a case of 75 years old woman with Reel syndrome presenting with syncope.
