Pulmonary artery-to-left atrial fistula discovered after the closure of atrial septal defect: A rare clinical scenario

A case of the right pulmonary artery-to- left atrial fistula with atrial septal defect (ASD) is presented. The fistula was detected after the patient developed desaturation following surgical closure of the ASD. It was managed with a transcatheter (trans-RPA route) closure of the fistula using a 12-mm Amplatzer ventricular septal defect closure device.
