background: controversy persists over the potential benefits/harms of opium consumption in coronary heart disease. this study investigated the association between 12 months' major adverse cardiac events (mace) and pre-procedural opium consumption among patients undergoing percutaneous coronary intervention (pci). methods: retrospectively, 1545 consecutive men who underwent pci between 21 st   j...

introduction: no-reflow phenomenon in coronary vessels, manifested in some patients with reperfused acute myocardial infarction (mi), is associated with poor clinical and functional outcomes. therefore, evaluation of predisposing risk factors can be helpful in risk assessment and identification of patients at higher risk. herein, we aimed to study the predictive factors for the development of n...

background: in this study, the early effects of percutaneous nephrolithotomy (pcnl) on glomerular filtration rate (gfr) was assessed in different postoperative times and likewise, we determined the correlation of different variables with significant postoperative gfr drop  after pcnl. m aterials and methods: patient records of 486 cases that had undergone pcnl from january 2010 to october 2011 ...

an 80-year-old diabetic man with severe aortic stenosis was admitted to our hospital for cardiogenic shock complicating non-st-elevation myocardial infarction. echocardiographic evaluation showed also a severe degree of both left ventricular dysfunction and mitral regurgitation. the patient was initially stabilized with inotropes and mechanical ventilation was necessary because of concurrent pu...

Background: This study aims to evaluate the effect of exercise training on heart rate variability (HRV) and to determine the correlation between parameters of HRV and the ejection fraction in patients with heart failure after percutaneous coronary intervention.Material and Methods: Fifty patients with left ventricular ejection fraction ≤ 40% undergone percutaneous coronary intervention were r...

background: this research compares the outcomes of percutaneous technique and open surgical peritoneal dialysis catheter placement in children. methods: in this randomized controlled trial, between 2010 and 2011,a total of 35 pediatric uremic patients were enrolled and randomized into two study groups. follow up data included duration of operation (minute), duration of hospitalization (days) an...

Background: The pelvic ring fractures (PRF) and acetabular fractures (AF) are among the major orthopedic injuriesassociated with high rates of morbidity and mortality. Open surgical stabilization is the standard treatment for themajority of these complications. Percutaneous minimally invasive surgical stabilization of the fractures has become anaccepted treatment method for th...

the overall rate of atrial pacing lead dislodgement is estimated to be about 3%. these leads are generally repositioned via a second operation through opening the pacemaker pocket. some operators have introduced percutaneous techniques using snare system or deflectable catheters for this purpose. in this article we present our experience with five cases of percutaneous lead repositioning. three...
