q RSNA, 2011 Coronary artery disease (CAD) is the most frequent cause of death in many developed countries ( 1 ), and there is a strong need for a noninvasive test that can reliably be used to delineate CAD without the use of ionizing radiation. Coronary magnetic resonance (MR) angiography has a history of nearly 20 years, and considerable technical advances have been made during this period ( ...

AIMS Increased plasma concentrations of B-type natriuretic peptide (BNP) and its precursor (proBNP) provide important prognostic information in patients presenting with acute coronary syndromes. Although a majority of these patients undergo early invasive assessment, the effects of coronary angiography per se on plasma BNP and proBNP concentrations are not known. We therefore sought to determin...

To date, only one third of patients, with stable angina, undergoing coronary angiography demonstrated obstructive coronary artery disease (CAD). Thus, identifying high sensitivity and specificity, low-cost, non invasive tests is crucial. Here we present the case of a patient, at a high risk of CAD, undergoing coronary angiography because of positive exercise test and stress imaging results, wit...

Introduction: Coronary angiography and angioplasty procedures lead to significant radiation exposure of patients. In the current study, the average radiation dose to patients during angiography in the Angiography Department of Shahid-Madani Hospital was determined. Materials and Methods: An image intensifier based angiography unit (Philips BH 3000) was used for angiography procedures. The accur...

Objectives Although echocardiography has traditionally been used to diagnose myxoma, invasive or non-invasive coronary angiography can be useful diagnostic tool before surgery. Methods We present a case of an angiographically detected left atrial myxoma feeding from the left circumflex coronary artery. Results The patient underwent open-heart surgery to remove the left atrial myxoma. After ...

BACKGROUND Computed tomography angiography enables non-invasive evaluation of the coronary arteries. OBJECTIVES To evaluate the accuracy of 16-slice multi-detector CT angiography in the diagnosis of coronary artery disease, and assess coronary bypass grafts and coronary anomalies. METHODS We conducted a retrospective study of 223 patients who were examined at our medical center over a perio...

This study evaluates the safety and clinical utility of rotational angiography in the diagnosis of coronary artery disease. High-speed rotational angiography is a newly available angiographic modality that gives a dynamic multiple-angle perspective of the coronary tree during a single contrast injection. We prospectively randomized 56 patients referred for diagnostic coronary angiography to eit...

OBJECTIVE  To evaluate whether invasive coronary angiography or computed tomography (CT) should be performed in patients clinically referred for coronary angiography with an intermediate probability of coronary artery disease. DESIGN  Prospective randomised single centre trial. SETTING  University hospital in Germany. PARTICIPANTS  340 patients with suspected coronary artery disease and a...
