title: [DDD pacemaker implantation in the patient underwent Maze procedure].
abstract: We reported a 26-year-old man with mitral regurgitation and sick sinus syndrome. He underwent VVI pacemaker implantation, and admitted to our hospital due to congestive heart failure. Echocardiography and cineangiography revealed severe mitral regurgitation. Mitral valvuloplasty and modified Maze procedure were performed, and a DDD pacemaker was implanted after cardiopulmonary bypass. We recognized cross stimulation 7 months after operation. The reason of the cross stimulation was the position of the implanted atrial lead, which was the low right atrium. Thus, an atrial lead of DDD pacemaker should be carefully implanted in the patients underwent Maze procedure.
