Summary
Is real-time myocardial perfusion echocardiography (RTMPE) a feasible and effective non-invasive method to detect significant Coronary Allograft Vasculopathy in pediatric and adult cardiac transplant recipients? Will perfusion deficits correlate with significant coronary artery stenosis identified by standard stress echocardiography and Invasive Coronary Angiography (ICA), and identify diffuse small vessel disease more effectively than current non-invasive techniques?
