Abstract
The pulsed Doppler echocardiographic (PDE) findings in a premature cyanotic infant with total anomalous pulmonary venous return to the coronary sinus are reported. Features that suggested the diagnosis of total anomalous pulmonary venous return were 1) an area of systolic‐diastolic turbulent flow posterior to the apparent left atrial border, which was interpreted as representing the convergence of pulmonary venous return to a common pulmonary vein, and 2) systolic and diastolic turbulent flow within the right atrium suggesting pulmonary venous return through the coronary sinus. We suggest that PDE should be included as part of the evaluation of cyanotic infants in whom the diagnosis of total anomalous pulmonary venous return is considered.
