Myocardial Tissue Doppler Changes in Patients with Bronchopulmonary Dysplasia

Increasing right ventricle E/E′ ratio correlates with clinical severity of BPD. Abnormal left ventricular myocardial performance index was noted to correlate with the grade of BPD. Further longitudinal studies of tissue Doppler echocardiographic assessment of cardiac function in premature infants with BPD are needed.
