An asymptomatic 10-year-old male visited his pediatrician for his regular attention deficit and hyperactivity disorder (ADHD) follow-up. A new systolic ejection murmur was heard. Chest x-ray showed an abnormal aortopulmonary window with enlargement of the left atrial shadow. ECG showed P-mitrale (M-shaped P-waves) in lead II and biphasic P-waves in lead V1, suggesting left atrial enlargement (Figure 1). These results prompted a referral to pediatric cardiology.
The first paper from the SCMR registry data, "Cardiac Magnetic Resonance Stress Perfusion Imaging for Evaluation of Patients With Chest Pain", has been published in the Journal of American College of Cardiology.
