  This case demonstrates the use of cardiac CT angiography as part of the preoperative evaluation of a recurrent subaortic membrane in a 23-year-old women. A subaortic membrane is a rare finding onThis case demonstrates the use of cardiac CT angiography as part of the preoperative evaluation of a recurrent subaortic membrane in a 23-year-old women. A subaortic membrane is a rare finding on coronary CT angiography and typically consists of a thin fibrous membrane in the left ventricular outflow tract (LVOT). The resulting turbulent flow may lead to LVOT obstruction and aortic insufficiency.

  Controversy still exists in the categorization of holes between the ventricles, although they are the most common congenital cardiac malformation. Advanced imaging techniques such asControversy still exists in the categorization of holes between the ventricles, although they are the most common congenital cardiac malformation. Advanced imaging techniques such as three-dimensional echocardiography and computed tomographic angiography offer superb anatomical details of these defects. In this review, we have sought to collate the features highlighted in different categorizations and identify their similarities, but also emphasize their differences. We hope that an analysis of this type, now achievable during life, using advanced imaging, might lead to the appearance of a unified system for diagnosis and description of holes between the ventricles.

• Computed Tomographic Angiography of Infants with Congenital Heart Disease Receiving Extracorporeal Membrane Oxygenation.

  Patients with respiratory and/or cardiac failure occasionally require the use of extracorporeal membrane oxygenation (ECMO), which presents an obstacle for standard imaging modalities. ComputedPatients with respiratory and/or cardiac failure occasionally require the use of extracorporeal membrane oxygenation (ECMO), which presents an obstacle for standard imaging modalities. Computed tomographic angiography (CTA) can be used in patients with congenital heart disease, usually to define extra-cardiac anatomy in the chest. We describe the use of CTA to evaluate two infants with congenital heart disease while on ECMO. The first infant had totally anomalous pulmonary venous connection, and the second had a pulmonary sling that resulted in tracheal stenosis. The studies achieved high diagnostic quality with minimal radiation exposure. Subsequently, both infants had successful surgical repairs.
