Preprocedural assessment of coronary artery disease in patients undergoing transcatheter aortic valve implantation: Rationale and design of the EASE‐IT CT registry

Julia Mascherbauer, Tanja Rudolph, Justus T. Strauch, Moritz Seiffert, more

European Journal of Clinical Investigation > 54 > 11 > n/a - n/a

Background Invasive coronary angiography (ICA) is the standard for pre‐procedural assessment of coronary artery disease (CAD) in patients undergoing transcatheter aortic valve implantation (TAVI). However, it requires hospitalization and can be associated with complications. Computed tomography angiography (CTA) may be a viable alternative to rule out prognostically relevant CAD. Methods The EASE‐IT...

Cong Luo, Chunrong Tao, Rui Li, Thanh N. Nguyen, more

European Journal of Neurology > 31 > 9 > n/a - n/a

Background and Purpose This study aimed to investigate the effect of collateral circulation on the outcomes of thrombectomy versus medical management alone in basilar artery occlusion (BAO) patients with varying stroke severities. Methods Data from the ATTENTION cohort were used to perform a post‐hoc analysis comparing the outcomes of thrombectomy with medical management in BAO patients with varying...

Multiple aortic root pseudoaneurysms with dissecting aneurysm of the interventricular septum diagnosed by multimodal imaging

Jingyi He, Jiahui He, Juan Xia, Xiaojing Ma, more

Echocardiography > 41 > 7 > n/a - n/a

Aortic root pseudoaneurysm is a devastating complication post aortic valve replacement with a high mortality rate. And dissecting aneurysm into the interventricular septum is a rare variant of aortic root pseudoaneurysm, which is scarcely reported. Multimodal imaging is of great value in its diagnosis and differential diagnosis.

Burak B. Ozkara, Mert Karabacak, Meisam Hoseinyazdi, Samir A. Dagher, more

Journal of Neuroimaging > 34 > 3 > 356 - 365

Background and Purpose We aimed to predict the functional outcome of acute ischemic stroke patients with anterior circulation large vessel occlusions (LVOs), irrespective of how they were treated or the severity of the stroke at admission, by only using imaging parameters in machine learning models. Methods Consecutive adult patients with anterior circulation LVOs who were scanned with CT angiography...

Longitudinal cardiac dimensions in patients undergoing LVAD implantation

Florian Meissner, Sophie Szvetics, Michelle Costa Galbas, Maximilian Russe, more

Artificial Organs > 48 > 5 > 550 - 558

Background In conventional left ventricular assist devices (LVAD), a separate outflow graft is sutured to the ascending aorta. Novel device designs may include a transventricular outflow cannula crossing the aortic valve (AV). While transversal ventricular dimensions are well investigated in patients with severe heart failure, little is known about the longitudinal dimensions. These dimensions are,...

‘No zone’ approach in the management of penetrating neck injuries – an Australian Tertiary Trauma Centre experience

Meera L. Chandrananth, Jordan D. Lee, David Read, Rose Shakerian

ANZ Journal of Surgery > 94 > 4 > 591 - 596

Purpose Penetrating neck injuries (PNIs), defined as deep to the platysma, can result in significant morbidity and mortality. Management has evolved from a zone‐based approach to a ‘no zone’ algorithm, resulting in reduced non‐therapeutic neck exploration rates. The aim of this study was to examine PNIs and its management trends in an Australian tertiary trauma centre, to determine if a ‘no zone’...

Automatic Segmentation of Calcified Plaques and Vessel Borders from Abdominal Aorta CTA Images Using a 2D Spatial Convolutional Multilayer Machine Vision Classifier

Chia‐Hung Lin, Ching Chou Pai, Chung‐Dann Kan, Jian‐Xing Wu, more

IEEJ Transactions on Electrical and Electronic Engineering > 18 > 2 > 254 - 269

The aorta, including the thoracic and abdominal aortas, distributes blood from the heart to the upper and lower circulatory systems. Abdominal aortic sclerosis can cause abdominal aortic aneurysm. When the diameter of the aorta increases by more than 1.5 times its normal size (e.g., ≥4−5 cm, mean diameter in an adult is 2−3 cm), the risk of aneurysm rupture gradually increases. Aneurysm rupture and...

Novel interrupted aortic arch: A case report

Yang Gan, Pei Zhang, Ruili Liao, Yongmei Nie, more

Journal of Cardiac Surgery > 37 > 12 > 5639 - 5642

Background and Aim of the Study Interrupted aortic arch (IAA) is a rare and fatal malformation. Most patients with IAA are diagnosed in early childhood because of the severity of their symptoms. IAA is classified into three morphologic types (A, B, or C), depending on the site of the interruption. In our case, this patient did not have a common brachiocephalic trunk, left carotid artery, or left...

Nicolas S. Poupore, W Nicholas Jungbauer, Shaun A. Nguyen, David R. White, more

The Laryngoscope > 133 > 1 > 25 - 37

Objective(s) To analyze the utility of computed tomography angiography (CTA) in identifying internal carotid artery (ICA) injury and reducing cerebrovascular accident (CVA) incidence in children presenting with normal neurologic exams after oropharyngeal trauma (OT). Data Sources PubMed, Scopus, CINAHL, and Cochrane. Review Methods A systematic review and meta‐analysis were performed following...

Predictive performance of J‐Calc‐CTO score for guidewire crossing through chronic total occlusion lesions within 30 minutes: J‐CTO score modified by computed tomography coronary angiography

Yohsuke Honda, Masahiro Yamawaki, Shinsuke Mori, Masakazu Tsutsumi, more

Catheterization and Cardiovascular Interventions > 100 > 4 > 560 - 567

The original J‐CTO score predicts the difficulty of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions, but the grade of calcification has not been fully evaluated. We examined 137 patients (141 CTO lesions) who underwent coronary computed tomography angiography (CTA) pre‐PCI between October 2016 and October 2021. They were randomly divided into derivation (n = 94)...

Ling Zhou, Chen Chen, Minjuan Zheng, Lu Liu, more

Echocardiography > 39 > 9 > 1252 - 1258

Background There are differences between young and older patients diagnosed with acute aortic dissection. We aimed to explore the differences in echocardiographic and computed tomography angiography (CTA) characteristics between the young and the older patients diagnosed with acute aortic dissection.

Proximal interruption of the right pulmonary artery: A rare anomaly

Aprateem Mukherjee, Niraj Nirmal Pandey, Sivasubramanian Ramakrishnan, Priya Jagia

Journal of Cardiac Surgery > 37 > 7 > 2094 - 2095

We report a case of a 21‐year‐old woman with cyanosis where computed tomography (CT) angiography revealed a complete absence of the mediastinal part of the right pulmonary artery with the normal intrapulmonary vascular network, receiving supply from multiple collateral vessels. The case also highlights the various differential diagnoses and the role of CT angiography in arriving at the correct diagnosis.

Mansi Verma, Niraj Nirmal Pandey, Sanjeev Kumar, Sivasubramanian Ramakrishnan

Journal of Cardiac Surgery > 37 > 6 > 1725 - 1727

We present a case of a 6‐year‐old boy with a double outlet right ventricle where the independent origin of all three coronary arteries from a single sinus of Valsalva was incidentally detected on CT angiography. The case highlights the role of CT angiography in identifying coronary arterial anomalies in the setting of complex congenital heart diseases.

“Ground‐cherry” appearance of the pulmonary trunk: Incidentally detected sinoatrial nodal branch‐to‐pulmonary trunk fistula

Aprateem Mukherjee, Niraj Nirmal Pandey, Sanjeev Kumar

Journal of Cardiac Surgery > 37 > 5 > 1408 - 1409

We present a case of a 45‐year‐old man with atypical chest pain who underwent coronary computed tomography angiography which incidentally revealed a conglomerate of nondilated tortuous vessels along the inferior half of the surface of the pulmonary trunk, resulting in a “ground‐cherry” like ridged appearance. Tracing these vessels proximally and distally revealed it to be arising from the sinoatrial...
