BACKGROUND AND OBJECTIVES Coronary angiography (CAG) is the gold standard for diagnosing coronary artery disease. However, exposure to ionizing radiation delivered during CAG has various negative biological effects on humans. In this study, there was an evaluation of whether fluorography resulted in decreased radiation exposure, as compared with cineangiography. SUBJECTS AND METHODS Fifty-fiv...

Multi-Detector Computed Tomography (MDCT) has been used to detect coronary lesions in a number of earlier studies. Here, we describe a rare case of congenital anomaly of the coronary artery, i.e., the R-II-B subtype (Lipton classification) of single coronary artery (SCA). A 61 year old man with angina was referred to our hospital. Assessment by coronary angiography (CAG) suggested SCA. The R-II...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Coronary artery calcium (CAC) is an independent predictor cardiovascular events. While it traditionally performed utilizing gating with specific acquisition parameters, CAC can be identified in non-gated standard chest computed tomography (CT). This study aimed to assess on CTs, evaluating its correlation coronary les...

Conventional coronary angiography (CAG) has limitations in evaluating lesions producing ischemia. Three dimensional quantitative coronary angiography (3D-QCA) shows reconstructed images of CAG using computer based algorithm, the Cardio-op B system (Paieon Medical, Rosh Ha'ayin, Israel). The aim of this study was to evaluate whether 3D-QCA can reliably predict ischemia assessed by myocardial fra...

We encountered two consecutive cases with spontaneous ST elevation due to right coronary spasms and subsequent ventricular fibrillation (VF). Their 12-lead ECGs on anterior chest pain showed elevation of ST-segments in the inferior leads, but coronary angiography (CAG) revealed no significant stenosis. Both cases showed dramatically evolving J waves in the inferior leads during the right CAG, b...

Introduction: Coronary artery disease secondary to atherosclerosis is the most common cause of mortality. Coronary angiography is the most precise method for determining the extent of disease in the coronary vascular bed. Arterial stiffness has been proposed as a marker of atherosclerosis in some studies. One of the noninvasive methods for the determination of arterial stiffness is Doppler echo...

conclusions in most cases, the conus artery can be visualized in cardiac ct. a description of the conus artery should be a part of the standard clinical coronary ct angiography description. objectives to examine whether it is possible to visualize the conus artery in multi-slice computed tomography (ct). patients and methods in 79 consecutive patients (aged 56 ± 12.9 years; 13 women), 64-slice ...

Takayasu's arteritis can involve the ostia of coronary arteries. We report a patient with Takayasu's arteritis involving the ostia of three large coronary arteries who was successfully treated by percutaneous coronary intervention (PCI) with a drug-eluting stent (DES) and had a good clinical outcome after 12 months. A 37-year-old male with unstable angina was admitted to our cardiovascular cent...

Background: Transradial access is one of the main access techniques in angiography. This method is technically more difficult as it is associated with radial artery occlusion. Radial artery cannulation from the dorsal surface of the hand in the snuffbox area has been introduced as a suitable solution to overcome some of the disadvantages of the standard radial artery method. This study was cond...

OBJECTIVE Acute myocardial infarction is a major cause of out-of-hospital cardiac arrest (OHCA). Coronary angiography (CAG) enables diagnostic confirmation of coronary artery disease and subsequent revascularization, which might improve the prognosis of OHCA survivors. Non-randomized data has shown a favorable impact of CAG on prognosis for this population. However, the optimal timing of CAG ha...
