results the degree of systolic compression was found to be correlated with the depth of the mb. however, there was no correlation between the length of the mb and the degree of systolic compression. conclusion the systolic compression of the mb was influenced by the depth of the tunneled segment, not by its length. background myocardial bridging (mb) is a congenital anomaly in which a segment o...
Background: Intravascular imaging is a tool to detect coronary artery atherosclerosis which plays the major role in vessel stenosis degree determination and plaque pathology as a supplement of invasive angiography. This study aimed at comparing Intravascular imaging with invasive angiography. Materials and Methods: For retrieving second type studies, PubMed, Cochrane Library and Centre for R...
cardiovascular disease remains the principal cause of death in the modernized world. several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease. of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...
Introduction: Invasive diagnostic procedures such as coronary angiography, in most cases, are accompanied by stress and anxiety for patients,which may effect on hemodynamic signs. Materials and Methods:This research, as a quasi experimental study, has the objective to determine the influence of applying methods of relaxation on hemodynamic signs in hospitalized 40 patients, experienciny corona...
O ne million patients undergo invasive coronary angiogra-phy (CA) in the United States every year. 1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for ischemic coronary artery disease (CAD)....
Background & Aim: Coronary artery disease is one of the most common diseases in different societies. Coronary angiography is established as one of the best methods for diagnosis of this disease. Angiography is an invasive and costly method. Furthermore, it is associated with risks such as death, heart attack, and stroke. Thus, this study introduces a neuro-fuzzy-based method which can help the ...
This study was conducted on a human anthropomorphic phantom to investigate the effective dose and entrance skin dose (ESD) in selected radiosensitive organs through invasive and computed tomography (CT) coronary angiography procedures using different dose-saving techniques. The effective dose was calculated as 2.49, 3.35 and 9.62 mSv, respectively, corresponding to three coronary CT angiography...
We present the case of a 5-year-old child with coronary complications due to Kawasaki disease; this patient unintentionally underwent both dual-source computed tomography (DSCT) coronary angiography and invasive coronary angiographic examination in 2 months. This case highlights the strong consistency of the results between DSCT coronary angiography and invasive coronary angiography. Compared t...

Background and Purpose: Anxiety is a common problem associated with invasive medical procedures, especially in patients undergoing coronary angiography. As an intensifier at cardiovascular reactions, anxiety poses significant risk to the health of patients undergoing angiography. Researchers believe that use of Benson’s relaxation technique could reduce anxiety in different patients. Th...
