background: coronary angiography is frequently applied for diagnostic purposes in patients with coronary artery disease. be that as it may, there is still no consensus about the optimal time for the ambulation of patients following femoral arterial puncture. we sought to compare 6 hours of complete bed rest and 2 hours of complete bed rest in patients after angiography. methods: this randomized...

background: atherosclerotic renal artery stenosis (aras) remains underdiagnosed due to its nonspecific demonstrations. we aimed to both estimate the frequency of aras in high-risk non-selected patients undergoing simultaneous coronary and renal catheterization and possibly identify a predictive model for aras using baseline clinical, laboratory, and coronary angiographic variables. methods: the...

Abstract Coronary Artery Disease (CAD) is commonly diagnosed using X-ray angiography, in which images are taken as radio-opaque dye flushed through the coronary vessels to visualize severity of vessel narrowing, or stenosis. Cardiologists typically use visual estimation approximate percent diameter reduction stenosis, and this directs therapies like stent placement. A fully automatic method seg...

BACKGROUND There is a high incidence of anomalous coronary arteries in subjects with congenital heart disease. These abnormalities can be responsible for myocardial ischemia and sudden death or be damaged during surgical intervention. It can be difficult to define the proximal course of anomalous coronary arteries with the use of conventional x-ray coronary angiography. Magnetic resonance coron...

The coronary angiography image is easy to be affected by many factors, such as vascular thickness varied huge, complex background noise, uneven illumination intensity and so on. The coronary angiography image is more difficult to deal with compared with other similar medical images. By using Hessian matrix multi-scale vascular detection method, the vicinity of blood vessels will yield a lot of ...

background: coronary angiography is recognized as the gold test for diagnosis of coronary artery diseases. based on the literature review, little is known about patients’ expectations about this procedure. understanding the patient’s expectations is an important way to achieve patient‑centered care. the purpose of this study was to explore the expectations of iranian patients undergoing coronar...

A 12 year-old girl with corrected transposition (Ltransposition of the great arteries with ventricular inversion) and congenital complete atrioventricular block underwent epicardial pacemaker implantation with a single ventricular lead at 1 week of life. Subsequently, she presented for routine follow-up care in the electrophysiology clinic with no symptomatic concerns. She denied chest pain. He...
