Why the study?
Stent implantation for pulmonary artery stenosis after arterial switch operation carries risks related to coronary artery compression.
Does coronary compression testing identify risk of coronary artery compression before pulmonary artery stenting in patients with a history of arterial switch operation?
Does coronary compression testing identify risk of coronary artery compression before pulmonary artery stenting in patients with a history of arterial switch operation?
Coronary balloon testing should be systematically considered before pulmonary artery stent implantation in patients with a history of arterial switch operation to prevent coronary compression.

Case suggests coronary compression testing before post-ASO stenting; leaves open prospective validation of routine use.
Pulmonary artery stenosis is one of the most common complications after arterial switch operation. Stent implantation is an effective treatment with some risks related to coronary artery compression. We present the case of a patient affected by pulmonary stenosis after arterial switch operation. Coronary compression testing demonstrated compression of the left coronary artery from the balloon inflated in the left pulmonary artery. We should systematically consider the use of coronary balloon testing before stent implantation in patients with a history of switch operation.
