Inpatient coronary angiography and revascularisation following non-ST-elevation acute coronary syndrome in patients with renal impairment: a cohort study using the Myocardial Ischaemia National Audit Project. [PDF]

, 2014
BACKGROUND: International guidelines support an early invasive management strategy (including early coronary angiography and revascularisation) for non-ST-elevation acute coronary syndrome (NSTE-ACS) in patients with renal impairment.

Unusual case of single coronary artery with anomalous RCA from LAD: The ultimate of cardiac CT

IHJ Cardiovascular Case Reports, 2021
Coronary artery anomalies are found in 0.6%–1.55% of patients who undergo coronary angiography, and the increasing use of diagnostic coronary angiography is unveiling even more complex coronary anomalies.

Coronary CT Angiography in Managing Atherosclerosis [PDF]

International Journal of Molecular Sciences, 2015
Invasive coronary angiography (ICA) was the only method to image coronary arteries for a long time and is still the gold-standard. Technology of noninvasive imaging by coronary computed-tomography angiography (CCTA) has experienced remarkable progress during the last two decades. It is possible to visualize atherosclerotic lesions in the vessel wall in

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Utility of Cardiac Computed Tomography in the Diagnosis of Apical Hypertrophic Cardiomyopathy: A Case Series

Heart Views
Hypertrophic cardiomyopathy (HCM) is characterized by abnormal thickening of the left ventricular myocardium. Apical HCM is a less common variant of HCM where the hypertrophy is limited to the apical segments and can be challenging to diagnose based on ...
