Surgical Repair of Tetralogy of Fallot with Large Conus Artery

The large conus artery transversing the right ventricular outflow tract may cause more confusion and concern in the surgery of tetralogy of Fallot with a small pulmonary annulus than other well-known coronary anomalies. We experienced an infantile case that precipitated into a critical left ventricular failure caused by transection of a large conus artery for the transannular right ventricular outflow tract reconstruction and rescued the patient with an extracorporeal lung–heart-assist system. Preoperative precise diagnosis of coronary anatomy should serve to protect against fatal mistakes, and various techniques for repair must be chosen individually for this subset of anomalies.
