Coronary CT Angiography as an Alternative to Invasive Coronary Angiography [PDF]

, 2011
X-ray computed tomography (CT) was first invented in 1972 and its ability to obtain cross sectional images has proven to be a major advance in the field of medicine, garnering the Nobel Prize in medicine for Sir Godfrey Newbold Hounsfield and Allan McLeod Cormack in 1979.

Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Do consumers and healthcare professionals report the same adverse event differently? A paired analysis of duplicate vaccine safety reports in Norway

British Journal of Clinical Pharmacology, EarlyView.
Aim This study aimed to compare how Norwegian healthcare professionals (HCPs) and consumers reported the same adverse event (AE) following immunization with vaccines against COVID‐19 during the COVID‐19 pandemic. Specifically, we aimed to compare the extent to which HCPs and consumers reported information relevant for assessing the causal relationship ...

The diagnostic value of low-dose chest computed tomography for calcium score determining compared with the standard method and the results of computed tomography and selective coronary angiography

Российский кардиологический журнал, 2019
Aim. Coronary artery calcification is a characteristic of coronary atherosclerosis, which is often detected by chest computed tomography (CT). The aim of this study is to assess the efficiency of low-dose chest CT in calcium score (CS) determining and to

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.
