SHAPE OF THE RIGHT VENTRICULAR OUTFLOW TRACT DOPPLER ENVELOPE IS A SENSITIVE PREDICTOR OF ALTERED PULMONARY HEMODYNAMICS IN PEDIATRIC PATIENTS

The shape of the RV outflow tract (RVOT) Doppler velocity envelope (DVE) has been shown to be a sensitive marker of altered pulmonary hemodynamics in adults, but this has not been validated in children. Systolic deceleration or ‘‘notching’’ of the RVOT DVE relates to the pathologic wave
