Coronary allograft vasculopathy fails to give a warning anginal pain due to denervation and often presents with acute coronary syndrome, ventricular dysfunction, or sudden cardiac death. Early diagnosis in a pediatric patient is difficult as it involves invasive coronary angiography or advanced imaging such as intravascular ultrasound or optical coherence tomography. A 12-year-old boy developed acute coronary syndrome, elevated troponins, and right bundle branch block, 5 years after cardiac transplantation and was treated with culprit-vessel angioplasty with a drug-eluting stent. Advanced imaging showed the involvement of nonculprit vessels too. In a detailed literature search, we failed to identify a similar clinical presentation and management in the subcontinent, hence our interest in publishing this report for educational value. Issues in diagnosis, management, prognosis, and prevention are discussed.
