Core Tip
Core tip: Cor triatriatum dextrum is an extremely rare congenital heart abnormality in which the right atrium is separated by a persistent fibrous membrane. This membrane poses a technical challenge for dual-chamber pacemaker placement through the transvenous approach. Here we report the first transvenous pacemaker placement in a patient with cor triatriatum dextrum. A thorough pre-operative evaluation by transesophageal echocardiogram was critical for the planning of transvenous catheter-based right-sided leads placement. Using specially designed pacemaker leads and cautious intra-procedural maneuvering under fluoroscopic guidance ensured procedural success.
