Few cases of a floating thrombus in a normal aorta have been reported without other underlying reasons for the thrombus formation and its systemic embolic complications. We report a case in which a floating thrombus in the proximal aortic arch was detected after echocardiography and computed tomography angiography as an origin of upper extremities and(More)
The decision to proceed with triple-valve surgery should take into account reasonable estimates of the risk of the surgery and of the potential benefit to be gained. In the present study, we reviewed our experience with triple-valve surgery, focusing on short-term death and morbidity, mid-term survival, and postoperative quality of life.Among 107 patients(More)
Behcet's disease is a multisystem disorder and classified as "vasculitic syndrome with a wide variety of clinical manifestations." Cardiac involvement is very rare but can occur with different presentations including: pericarditis, cardiomyopathy, endocarditis, endomyocardial fibrosis, intracavitary thrombosis, and coronary artery disease.

Cardiac inflammatory myofibroblastic tumor is a rare lesion consisting of inflammatory cells and myofibroblastic spindle cells. We describe a case of inflammatory myofibroblastic tumor that involved the right ventricle, thereby causing tricuspid valve regurgitation in an 18-year-old man who presented with a fever of unknown origin and of 1 month's duration.(More)
OBJECTIVE Evaluating renal function by calculating creatinine clearance as an alternative measure to serum creatinine may give a better estimation of postoperative renal function in patients undergoing coronary artery bypass grafting. METHODS Using our database, we conducted a retrospective review of the records of all 11,884 patients aged 21 years or(More)
INTRODUCTION AND OBJECTIVES Atrial arrhythmias occur after cardiac surgery in 10-65% of patients. The most common postoperative arrhythmia is atrial fibrillation (AF). METHODS The Tehran Heart Center Cardiovascular Research database (of 15 580 patients) was used to identify all patients who developed any form of AF as a postoperative complication(More)
OBJECTIVE It is well known that the traditional cardiac risk factors (TCRFs) affect short-term and long-term outcome following coronary artery bypass graft surgery (CABG). The objective of this study was to detect the prevalence of these risk factors i.e., hypertension, diabetes mellitus, hyperlipidaemia, smoking and family history of premature CAD in an(More)
OBJECTIVE Opium is an overwhelming public health problem in some countries. Different studies have suggested this drug as a risk factor for cardiovascular disease. Although the effect of opium on immune system, lung disease, nephropathy, stroke, and cardiac arrhythmia has been found in different studies, its effect on postoperation complications is not(More)
Our goal was to investigate the safety of single- and double-vessel coronary endarterectomy as an adjunct to coronary artery bypass grafting in patients with diffuse coronary disease. In reviewing the records of 9,443 patients who underwent isolated coronary artery revascularization over a 4-year period, we found 310 patients (3.28%) who underwent(More)
OBJECTIVE The aim of the present study was to investigate the determinant factors of acute renal failure (ARF) after isolated on-pump coronary artery bypass grafting (CABG). SUBJECTS AND METHODS This was a retrospective study of 13,315 adult patients who underwent isolated CABG with cardiopulmonary bypass (CPB) in Tehran Heart Center from May 2002 to May(More)
