Transcatheter Treatment of Native Idiopathic Multiloculated Aortic Aneurysm Guided by 3D Printing Technology.

Pediatric idiopathic aortic aneurysm is rare. Single saccular malformation can complicate native or recurrent aortic coarctation; however, multiloculated dilatations of the descending thoracic aorta, associated with aortic coarctation, have so far never been described in literature. In our case, printed 3D model technology was crucial in planning transcatheter treatment.

A simple method to visualize the bicuspid aortic valve pathology by cardiac computed tomography.

Bicuspid aortic valve (BAV) disease is a spectrum of anomalies ranging from mild underdevelopment of a commissure to severe underdevelopment of two interleaflets triangles. Many different classifications of BAV, based on the echocardiographic, surgical or pathological appearance of the valve, and more recently on cardiac CT, have been proposed. We describe a simple technique, based on three-dimensional curved multiplanar reconstruction images, to obtain a pathology-like visualization of the full line of insertion (Hinge) of the aortic valve leaflets and of the interleaflet triangles with cardiac CT.

Massive Hemoptysis from a Pulmonary Artery Pseudoaneurysm during Cardiac Surgery.

Massive hemoptysis is a life-threatening condition usually related to a pathology of the bronchial arteries. Pulmonary artery pseudoaneurysms represent a relatively rare cause of severe airway bleeding, but are associated with a mortality rate of over 50%. A case of massive intraoperative hemoptysis treated with temporary occlusion of the right pulmonary artery and delayed endovascular occlusion of the feeding segmental artery is described.

Sixteen-row multislice computed tomography in infants with double aortic arch.

Background: The introduction of multislice computed tomography (MSCT) in 1998 has led to a considerable boost of CT angiography. Four-row MSCT has been employed in the diagnostic assessment of vascular rings. Sixteen-row MSCT is expected to further increase the diagnostic power of MSCT.
