A 52-year-old man with left atrial tachycardia underwent radiofrequency catheter ablation. A steerable 4-mm-tip ablation catheter was advanced into the left atrium through a patent foramen ovale without transseptal puncture. However, the tip of the catheter was stuck in a structure. A pull-back maneuver rendered the catheter free and the procedure was cancelled. Transthoracic and transesophageal echocardiograms obtained immediately after the procedure showed intimal layer dissection in the interatrial septum and intramural hematoma formation throughout the anterior left atrial wall. The patient was in stable condition. Therefore, he was followed-up conservatively with serial echocardiographic examinations. The dissected intimal layer disappeared in 10 days and the hematoma underwent near-complete resolution in three months. This case highlights a rare complication of catheter ablation procedure that all interventionists should be familiar with.
