Left atrial intramural haematoma-a rare complication following radiofrequency ablation of atrial fibrillation: a case report.

ABSTRACT:

Background

Ablation is increasingly used to treat atrial fibrillation (AF), and recognizing potential complications is essential. We present a case of left atrial intramural haematoma after radiofrequency ablation (RFA), successfully managed with a conservative approach.

Case summary

A 39-year-old man underwent pulmonary vein isolation (PVI). During RFA with a contact-force catheter, the areas close to the left superior pulmonary vein, including the left atrial appendage, roof, and posterior wall, showed absent electrical signal. Left atrial scarring was suspected. PVI was completed. On the following day, the patient had chest pain. Transthoracic echocardiography revealed pericardial effusion and a large left atrial mass. Computed tomography confirmed a left atrial intramura
