Asymptomatic Right Ventricular Perforation by a Temporary Transvenous Pacing Lead in an Infant.

UNLABELLED: A 3-month-old male infant received transvenous temporary pacemaker for acquired complete atrioventricular block. However, a right ventricle perforation by the pacing lead was found incidentally when the patient was receiving permanent pacemaker implantation nineteen days after temporary pacing. There was no pacemaker dysfunction, active bleeding or hemopericardium. The temporary pacing lead was extracted and the site of perforation was sutured. This case is unique because of the patient's unusual clinical presentation, and we suggested that echocardiography should be performed cautiously to check the pacing catheter tip daily, even if asymptomatic and/or normal function of pacemaker. KEY WORDS: Complete atrioventricular block; Right ventricle perforation; Transvenous pacing lead.
