As surveillance and the diagnosis of pathology grow, increasing numbers of patients are undergoing major aortic interventions globally. As a result, surgeons and physicians will encounter thoracic aortic graft infections with increasing frequency. These infections are extremely challenging, high‐risk problems to deal with. This article provides a comprehensive overview of the pathogenesis, diagnosis, and management both medical and surgical of this high‐risk complication. We provide proposed diagnostic criteria and suggested algorithm for the management of this important group of patients. [ABSTRACT FROM AUTHOR]

The left ventricular outflow is an anatomically complex region situated between the anterior leaflet of the mitral valve and the left ventricular aspect of the muscular and membranous interventricular septum. It gives rise to the aorta, provides support to the aortic valvular cusps, and houses important components of the conduction system. The left ventricular outflow handles high pressures and pressure variations and is subsequently affected by a variety of aetiopathological conditions. Diseases involving the left ventricular outflow can be intraluminal, mural, or extramural, and the consequent complications of the lesions can be local, loco-regional, or even systemic. Appropriate evaluation requires comprehensive multimodality imaging with each modality contributing to assessment of different aspects of diagnosis, lesion characterization, local extension, prognostication for systemic complications and mortality, and the decision for the approach and type of intervention and aggressive follow-up in case non-interventional management is decided. In this review, we briefly describe the relevant anatomy and the gamut of structural abnormalities pertaining to the left ventricular outflow on multidetector computed tomography angiography.

Aim: To evaluate the imaging characteristics and associations in patients with isolation of arch vessels on multidetector computed tomography angiography (CTA). Materials and Methods: We retrospectively reviewed all multidetector CTA studies performed for the evaluation of congenital heart diseases (CHDs) at our institution from January 2014 to June 2020. Cases with isolation of arch vessels were identified. The isolated arch artery and its relationship with patent arterial duct, pulmonary artery, and aortic arch were characterized in addition to other associated intra‐ and extracardiac anomalies. Results: Isolation of arch vessels was seen in 14/3926 (0.36%) patients. Left subclavian artery (SCA) was the commonest isolated arch vessel, involved in 7/14 (50%) cases. Isolation of right SCA, left brachiocephalic artery, and left common carotid artery was seen in 4 (28.6%), 2 (14.3%), and 1 (7.1%) patient, respectively. The isolated arch vessel was seen associated with right aortic arch in 10/14 (71.4%) cases and was on the opposite side of aortic arch in all 14 (100%) patients. Right‐sided nonrestrictive patent arterial duct was seen in 3/14 (21.4%) cases, left‐sided nonrestrictive patent arterial duct was seen in 1/14 (7.1%) while a left‐sided restrictive patent arterial duct was seen in 3/14 (21.4%) cases. Tetralogy of Fallot (ToF) was the commonest associated anomaly seen in 8/14 (57.1%) patients. Conclusion: Isolation of aortic arch branch vessels is rare, seen most commonly associated with ToF. Left SCA is the commonest involved vessel. CTA is useful not only in the diagnosis of isolation of arch vessels, but also in the presence or absence of associated anomalies which may impact the symptomatology, prognosis, and surgical management.

We present a case of a 4‐year‐old boy with tuberculosis‐associated mediastinal fibrosis with concomitant pulmonary arterial and venous occlusion, highlighting the role computed tomography angiography in identification of the disease process, coexistent vascular abnormalities and associated complications.

We report a case of a 9-month-old boy with supracardiac total anomalous pulmonary venous connection showing a small aberrant vessel arising from the right pulmonary artery and traversing below the left main bronchus to supply the anteromedial segment of the left lower lobe. [ABSTRACT FROM AUTHOR]
