Coronary Flow Reserve Measurement Detects Transplant Coronary Artery Disease in Pediatric Heart Transplant Patients

CFR and coronary vasoreactivity to adenosine are decreased in pediatric patients with CAV and correlate with histopathologic and angiographic evidence of microvascular disease. Measurement of CFR with intracoronary and systemic application of adenosine is comparable, while systemic application is necessary for non-invasive measurement of CFR in pediatric patients.
