“…Cor triatriatum sinister is a rare congenital cardiac anomaly, most often diagnosed during childhood or infancy [ 1 , 2 , 3 , 4 , 5 , 6 ]. When it is diagnosed in adults, the most common presentation is for new onset atrial fibrillation [ 2 , 5 , 6 , 7 ].…”

“…Cor triatriatum is a rare congenital cardiac anomaly that accounts for 0.1 to 0.4% of all congenital heart disease [ 1 , 2 , 3 , 4 , 5 ]. The left-sided anomaly cor triatriatum sinister (CTS) is more frequent than the right-sided cor triatriatum dexter, with both conditions being commonly diagnosed in infancy and associated with other congenital heart defects such as atrial septal defect, patent foramen ovale or left superior vena cava [ 1 , 2 ].…”

“…In CTS, abnormal fibromuscular septation divides the left atrium into two separate chambers: the pulmonary chamber, usually located posteriorly and superiorly, which most frequently receives the four pulmonary veins, and the true left atrium, located anteriorly and inferiorly, which contains the left atrial appendage and the mitral valve annulus [ 1 , 2 , 3 , 4 , 5 , 6 ].…”

Atrial fibrillation is the most common presentation in adult patients with cor triatriatum sinister. The key to successful and safe catheter ablation in these patients is an accurate exploration and thorough understanding of the left atrial anatomy, both before and during the procedure. Catheter manipulation is highly dependable on left atrial anatomy, including the interatrial septum, insertion of pulmonary veins and cor triatriatum membrane. Anatomical variants such as the left common pulmonary trunk may influence the ablation approach and outcome. We report the case of a 52-year-old patient with cor triatriatum sinister and the left common pulmonary vein variant who underwent successful high-power, short-duration catheter ablation for paroxysmal atrial fibrillation.

Key Clinical MessageCor triatriatum is a rare congenital heart abnormality in which a membrane separates the left atrium (LA; sinister) or the right atrium (dexter) into two compartments. It is also a long‐forgotten cause of atrial fibrillation (AF) and substantially higher rates of blood stagnation, particularly proximal to the additional septum in the LA. In this case report, we faced a CHA2DS2‐VASc score of 1 in patients with non‐valvular AF due to Cor triatriatum sinister (CTS). The decision to start anticoagulants in this particular case was controversial, so we reviewed the literature to assess and address it. We present our case and discuss the indication of anticoagulants in this unique clinical scenario, accompanied by a literature review. Facing this dilemma of starting anticoagulants in special cases of CTS and AF should be individualized and need more investigation. However, till this moment, based on similar reports, it seems to be rational to consider CTS Per se as an additional risk stratification marker beyond the CHA2DS2‐VASc score start anticoagulant until the surgical resection. Considering CTS as the sole indication of anticoagulant in patients with normal sinus rhythm is a complex matter that needs further investigation.
