We performed catheter ablation to septal superior vena cava (SVC)-right atrium (RA) junction rapid firing in a 57-year-old man with paroxysmal atrial fibrillation. He later experienced transient sinus node dysfunction resulting from injury to the sinus node artery (SNA), which branched only from the proximal region of the left circumflex artery. The direction of the SNA should be considered during catheter ablation at the septal SVC RA junction, especially if the sinus node is supplied by only one SNA from the right coronary artery or the left circumflex artery.
