introduction: this study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. materials and methods: this interventional study was conducted on 39 patients with coronary artery lesions, in whom zotarolimus-eluting stents (n=20), paclitaxel-eluting stents (n=11) and other stents (n=8) were deployed four tim...

background: revision and promotion of educational programs, as well as guiding such programs from the traditional to modern ones, have been one of the goals of educational planning in order to improve the educational status. the present study was performed based on the opinions of the cardiology assistants.   methods:  this research was a cross sectional study and all the participants included ...

background: the number of interventional cardiology procedures performed has increased rapidly over the past years. while these procedures help physicians avoid using highly complicated invasive methods, it usually leads to high levels of exposure to ionizing radiation of both patients and cardiologist. the dose received by the cardiologist during interventional cardiology procedures is determi...

introduction: due to the large number of pet systems available in the market, it is not very easy to decide about the scanner of choice. conducting a research in order to compare all different pet scanners is very time consuming and expensive and practically impossible. however, such comparison may be conducted using pet simulators. in this study, the performance of 6 different pet scanners in ...

background: coronary artery disease (cad) is accountable for more than 30% of deaths worldwide and is, thus, deemed the most important factor in terms of disease burden around the globe. this study aimed to evaluate cad and its risk factors in hospitalized patients in the east azerbaijan province, northwest iran, from 2006 to 2007. methods: data on 18.323 patients hospitalized due to cardiovasc...

introduction: there are several technical features that make pet an ideal device for the noninvasive evaluation of cardiac physiology. organ motion due to respiration is a major challenge in diagnostic imaging, especially in cardiac pet imaging. these motions reduce image quality by spreading the radiotracer activity over an increased volume, distorting apparent lesion size and shape and reduci...

introduction the increasing practice of interventional fluoroscopy in diagnosis and treatment of cardiovascular disease has risen attention to improve radiation protection of patients and cardiologists in these relatively high dose techniques. therefore, nowadays there is an emphasis on the measurement of radiation dose received by patients and cardiologists arising from the relevant procedures...
