Case Report (n=1)
This case highlights a rare double venous anomaly (LSVC and IVC draining into the coronary sinus) that can complicate electrophysiological procedures like AV node ablation.
Cardi et al. (2021) conducted a case report in Dilated coronary sinus, heart failure, atrial fibrillation (n=1). Single-lead pacemaker implantation and aborted AV node ablation was evaluated. A rare double venous abnormality involving both a left superior vena cava and an abnormal inferior vena cava draining directly into the coronary sinus caused its massive dilatation.
