The coronary sinus (CS) and ligament of Marshall (LOM) have been reported to have arrhythmogenic properties and can initiate atrial fibrillation (AF) triggers as well as participate in left atrial reentrant circuits. In a recent study, epicardial and endocardial ablation of the CS in patients with AF after pulmonary vein isolation prolonged the AF cycle length and terminated AF and atrial tachycardia (AT). However, a few cases of CS ostial atresia (CSA) involving rare congenital cardiac anatomy exist. In these cases, ablation of the CS and LOM is difficult. We present a case of a 44-year-old man with CSA who underwent catheter ablation for AF and AT with a Brockenbrough needle puncture from the right atrium (RA) to the inside of the CS. Percutaneous pericardial puncture was used for the epicardial site.
