title: Total anomalous pulmonary venous connection to the unroofed coronary sinus in a neonate.
abstract: This report describes the unique case of a newborn with total anomalous pulmonary venous connection to an unroofed coronary sinus associated with Ullrich-Turner syndrome and aortic coarctation. Total anomalous pulmonary venous connection to the unroofed coronary sinus is an extremely uncommon cardiac abnormality. This congenital heart disease is difficult to diagnose and rarely ever reported. Few symptoms are to be expected when it is not associated with other congenital heart defects. This lesion results in a "naturally" corrected total anomalous pulmonary venous return and a coronary sinus atrial septal defect presenting as a left-to-right shunting lesion. Making the diagnosis of this cardiac defect, and if possible, surgical repair is of importance because cardiac dysfunction due to significant atrial left-to-right shunting is a known long-term complication in the older adult patient.
