Expectant management of prolonged hemolysis following complete transcatheter coil closure of a patent ductus arteriosus after previous pulmonary artery banding: a case report.

Background: Transcatheter coil occlusion has been the treatment of choice for closure of small patent ductus arteriosus (PDA). In spite of its safety, complications such as hemolysis still occasionally occur. And the hemolysis almost always occurs following partial transcatheter closure of PDA; hence, it occurs extremely rarely following complete transcatheter closure of PDA without residual ductal flow.

The morphogenesis and associated anomalous pulmonary venous drainage in sinus venosus defect.

Background: Sinus venosus defect (SVD) is an unusual type of interatrial communication (IAC) and is virtually always associated with partial anomalous pulmonary venous drainage (PAPVD) of the right pulmonary veins (RPV) to the superior vena cava (SVC) or right atrium (RA). However, its definite morphogenesis is still elusive, and diagnostic fallibility continues.

Methods: We conducted a retrospective review of the echocardiograms, cardiac catheterization data, computed tomographic findings, and surgical notes of 44 children with surgery-confirmed isolated SVD from 1977 to 2016.
