Acute Left Main Coronary Artery Compression After Harmony‐TPV Implantation

ABSTRACT We present an 18‐year‐old male with Fallot's tetralogy (ToF) repaired with a transannular and main pulmonary artery (PA) patch, who suffered an acute coronary artery compression after a Harmony‐TPV deployment. Left main coronary artery compression was confirmed with angiography and IVUS. He underwent emergent surgery, with a bioprosthetic valve replacement.
