introduction pulmonary vein (pv) isolation is considered as a key to atrial fibrillation (af) treatment. cryoballoon ablation is an effective therapy for pv isolation for af with minimal side effects and was approved by the us food and drug administration (fda) several years ago. successful isolation of pvs during cryoablation depends on the balloon temperature and helps in early identification...

hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. cardiac involvement is very rare, especially when there is not hepatic involvement. we describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to rajaei heart center, tehran, iran in 2012. her chest computed tomographic scan showed a cardiac mass. echocardiographic examination...

extracellular ca 2+ concentration ([ca2+]o) may be one of the factors affecting atrial natriuretic factor (anf) release. in the previous studies, there are opposite reports about the effect of [ca2+]o on anf secretion. therefore, the effect of [ca2+]o depletion on anf secretion and gene expression was studied in the present research. isolated right atria from rats were perfused for 6 and 2 hour...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction We have evidence that left atrial dysfunction and stunning occur after electric cardioversion for fibrillation (CAF). Additionally, successful to sinus rhythm, a dissociation between electrical mechanical recovery may be observed. Traditional pulsed Doppler tissue imaging parameters demonstrate reduced contractility i...

introduction: atrial fibrillation (af) is the most prevalent cardiac arrhythmias that cardiologists and internists encounter. the goal of this article is to clarify an overview of the evidence linking inflammation to af existence, which may highlight the effect of some pharmacological agents that have genuine potential to reduce the clinical burden of af by modulating inflammatory pathways. mat...
