aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. the most common cause of coronary artery aneurysms is atherosclerosis. angiography is the gold standard for diagnosis and treatment. depending on the severity of the coexisting coronary stenosis, patients with left main co...

Fourteen cases of inadvertent iatrogenic embolization of cerebral vessels occurring in a consecutive series of 3,731 angiographies in infants and children were studies. The incidence of embolization(0.9% of all patients ond 0.4% of all angiographic examinations) was about the same as has been reported in adults, but the clinical consequences were much milder, only one patient having documented ...

drome (APLS) may present with a catastrophic condition characterized by multiple vascular occlusions that often result in death if appropriate treatment is not quickly applied. In the great majority of cases, patients with catastrophic APLS show a spontaneous tendency to develop microvascular thrombosis that affects multiple organs. However, arterial reactivity leading to acute thrombosis after...

Background and Objective: Coronary artery disease (CAD) is one of the most common diseases today. Among the diagnostic methods, angiography is the main and gold standard in the diagnosis Since angiography is an invasive procedure, this procedure complications range widely from minor problems with short term sequelae to life threatening ones may cause irreversible damage or even death. Materials...

One might dismiss the article in this issue by Heiserman et al ( 1) on neurologic complications of cerebral angiography by arguing that it brings nothing new to the medical literature. Especially those of us who are quite senior neuroradiologists are familiar with the kinds of findings reported in this paper. The article reports a number of positive and negative correlations of neurologic compl...

OBJECTIVES To investigate whether additional resources for tertiary cardiology services, aimed at increasing coronary angiography and revascularisation rates, can improve socioeconomic equity of utilisation. DESIGN Cross sectional ecological study, using the Super Profile classification of enumeration districts and ischaemic heart disease (IHD) standardised mortality ratios (SMR) as a proxy f...

The plasma concentration, particle size, and chemical composition of high density lipoproteins (HDLs) are associated with the metabolism of triglyceride-rich lipoproteins (TGRLs). During alimentary lipemia there is active exchange of lipids and apolipoproteins between HDL and apolipoprotein B-containing lipoproteins. Whereas HDL has been assigned a protective role against the development of ath...

For automatic registration of 3-D models of the left atrium to fluoroscopic images, a reliable classification of images containing contrast agent is necessary. Inspired by previous approaches on contrast agent detection, we propose a learning-based framework which is able to classify contrasted frames more robustly than previous methods. Furthermore, we performed a quantitative evaluation on a ...
