Introduction <p>Echocardiographic algorithm based assessment of diastolic function during neonatal period could help in early identification of left ventricular diastolic dysfunction (LVDD) in infants with bronchopulmonary dysplasia (BPD).</p> Aim <p>To screen infants with BPD at 36 weeks postmenstrual age for LVDD.</p> Methods <p>We used conventional Doppler and myocardial deformation parameters suggested in the latest American Society of Echocardiography algorithm to evaluate LV function. Tricuspid-regurgitation velocity, LV shape, LV eccentricity and pulmonary ejection pattern were used to diagnose pulmonary hypertension (PH). The algorithm was then followed using age appropriate cut-off values to identify and grade LVDD.</p> Results <p>Scans of 71 control infants and 93 infants with BPD were analysed. We noted PH in 15% infants with BPD and 7% control infants. Grade 2 LVDD was seen in 5% infants with BPD compared to 1.4% control infants.</p> Conclusion <p>Rate of PH and grade 2 LVDD was significantly higher in infants with moderate to severe BPD.</p>
