Aortic Pseudoaneurysm following Ventricular Septal Defect Closure in a Pediatric Patient: A Case Report and Literature Review.

Aortic pseudoaneurysm, a rare condition characterized by localized transmural disruption and dilatation of the aorta, is very rare in the pediatric population. It is primarily caused by previous cardiovascular procedures such as aortic coarctation repair, aortic valve replacement, and subaortic membrane resection. We present a unique case of aortic pseudoaneurysm following surgery to repair a perimembranous ventricular septal defect in a 19-month-old boy who presented with fever as the sole symptom.

Synthesis and comparison of three photocatalysts for degrading tramadol as an analgesic and widely used drug in water samples.

Congenital Aorto-Cardiac Connections (CACC) Revisited: Introduction of a Novel Anatomic-therapeutic Classification.

Abnormal congenital aorto-cardiac communications (CACC) are a heterogeneous constellation of anomalies that provide an abnormal connection between the aorta and other cardiac chambers or structures, including the atria, ventricles, the main pulmonary artery, and the coronary sinus. The current terminology of CACC has significant errors and shortcomings including inconsistent and interchangeable use of terms of fistula and tunnel and lack of an inclusive classification with practical information on therapeutic management. The aims of this study were threefold: firstly, to perform a concise narrative review of congenital pathologic connections between the aortic root and cardiac chambers which include rupture of congenital sinus of Valsalva aneurysm, aorto-left ventricular and less commonly right ventricular tunnels, coronary cameral fistulas, and aorto-atrial communications; secondly, to investigate the differentiating features of the so-called aorta right atrial tunnel (ARAT), with and without coronary artery take-off from the tunnel, and coronary cameral fistula (CCF) by applying a differential diagnostic assistance toolbox to two groups of patients with ARAT and CCF; and lastly, to propose a practical and inclusive anatomic-therapeutic classification for CACCs.
