BACKGROUND The most important complication of atrial fibrillation (AF) is thromboembolic stroke. Although AF-related remodeling is considered important in atrial thrombogenesis, its role never has been directly tested. This study assessed effects of AF-related remodeling on the atrial thrombogenic milieu by using radiofrequency ablation (RFA) to create a quantifiable prothrombotic nidus. METH...
accessory pathways (ap) are abnormal myocardial connections between atria and ventricles with electrical conductive properties. we performed radio frequency (rf) catheter ablation in 66 patients with manifest ap at dr.shariati hospital during 5 years. bipolar mapping was used in 48 patients and unipolar mapping in 18 patients of find the best site for rf energy delivery. we calculated total dur...
As specialized compartments of the heart, the atria feature unique mechanical and structural properties that differ considerably from those of the ventricular myocardium. Beyond their contribution to cardiac output as a reservoir, conduit, and booster pump at different phases of the cardiac cycle, the atria determine heart rhythm, regularity, and rate (chronotropy). They also function as mechan...
We report a case of a 41-year-old man admitted with respiratory distress and found to have masses in both atria of the heart and in the testicle. The patient received palliative radiotherapy to relieving obstruction of blood flow tract caused by the intracardiac masses, followed by radical orchiectomy. After the diagnosis of testicular seminoma, he was treated successfully with 4 cycles of syst...
