Harmony-TPV implantation triggers acute LMCA compression requiring emergent surgery in a patient with rTOF.
Harmony-TPV deployment can cause acute left main coronary artery compression requiring emergent surgical intervention.
May warrant caution for coronary compression with Harmony-TPV in repaired TOF; leaves open optimal pre-procedural imaging strategies.
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.
