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 .
