BACKGROUND The BJUT-II VAD is a novel left ventricular assist device (LVAD), which is thought to have significant effects on the characteristics of aortic swirling flow. However, the precise mechanism of the rotational direction of BJTU-II VAD in the aortic swirling flow is unclear. MATERIAL AND METHODS A patient-specific aortic geometric model was reconstructed based on the CT data. Three pump...

BACKGROUND AND PURPOSE The objective of this study was to evaluate the relative value of high-resolution, contrast-enhanced MR angiography (CE MRA) with elliptical centric k-space ordering compared with intra-arterial x-ray angiography for imaging carotid stenosis. METHODS Thirty patients with suspected stenosis of the carotid arteries were examined with CE MRA (1.5-T scanner) and x-ray angio...

We report a case of a 32-week-gestation male who presented initially with symptoms suggestive of an interrupted aortic arch. The absence of a VSD prompted further investigations, including a CT angiogram, which revealed that he had an extensive thrombus in his aorta. He underwent a successful aortic thrombectomy with arch repair on cardiopulmonary bypass support. In view of the extensive thromb...

caspian miniature horse is a rare small horse in iran. in this horse, brachiocephalic trunk originates from the craniodorsal of the convex part of the aortic arch. it supplies the head, neck, forelimbs and cranial part of the thoracic cavity. in this reseach topographical location of brachiocephalic trunk arising from the aorta and its ramifications have been studied. five caspian miniature hor...

BACKGROUND Atherosclerotic aortic arch plaques (AAP) have been linked to an increased risk of thrombo-embolic events as a cause of acute ischemic stroke of undetermined etiology. OBJECTIVES To find out the presence of atherosclerotic plaques in aortic arch and their potential role as a source of embolism in cerebral infarction of undetermined etiology. METHODS We performed trans-esophageal ...

Two patients, aged 3 days (weight 2 kg) and 40 years (weight 80 kg) underwent gadolinium-enhanced magnetic resonance angiography (MRA) because of diagnostic uncertainty. The newborn infant was antenatally diagnosed with truncus arteriosis. Postnatal echocardiography confirmed the diagnosis. It was thought that the branch pulmonary arteries were confluent (type II); however, an MRA was requested...

PURPOSE Conventional surgical therapy of aortic arch aneurysms consists of aortic arch replacement requiring cardiopulmonary bypass and deep hypothermic circulatory arrest. This method is associated with significant morbidity and mortality, mainly due to neurologic complications and the sequelae of deep hypothermic circulatory arrest. Thus, it makes sense to work on developing less invasive sur...
