Percutaneous closure of a prenatally diagnosed large coronary artery fistula with an Amplatzer vascular plug immediately after delivery.

We describe successful percutaneous closure of a prenatally diagnosed large coronary fistula originating from the right coronary sinus and draining into the right ventricle in a one-day-old neonate using an Amplatzer vascular plug. Early intervention may be a useful tool in such cases with large fistulas to avoid complications such as severe congestive heart failure, myocardial ischaemia, need for assisted ventilation and longer hospital stay.
