Observation of renal function after multiple DE-MRI examinations in atrial fibrillation ablation patients without kidney diseases
نویسندگان
چکیده
Methods MRI was performed in 40 patients (27 males, age 62±9 years) who were scheduled for pulmonary vein isolation (PVI) and had a glomerularfiltration rate (GFR) of >30ml/min. A total of three MRIs were acquired prior to, directly after and 24 hours after PVI, using weightdependent dosages of gadolinium pententat (Gd-DPTA). 46,8±14,9 ml Gd-DPTA was given within a 3±1 day period. Renal function [defined as serum creatinine, blood urea nitrogen (BUN) and GFR] was measured before, acutely after and 12±2 weeks after the procedure. During follow-up, patients were examined for symptoms of NSF.

Objectives: Dual pathways have a determinant role in the occurrence of atrio nodal tachyarrhythmia (AVNRT). The aim of present study is to determine the role of slow pathway (SP) in the concealment zone and protective role of AV node during atrial fibrillation (AF). Material &Methods: In 7 isolated nodal rabbit preparation zone of concealment and concealed conduction is quantified by Specif...

Atrial fibrillation (AF) is associated with inflammatory and hypercoagulability state. Previous studies evaluated the safety and efficacy of dabigatran and warfarin in prevention of thrombothic complications. This study was intended to assess the influence of these drugs on hemostatic and inflammatory markers among patient underwent pulmonary vein ablation. A total of 100 patients with AF w...

Background—Kidney function is a known predictor of cardiovascular morbidity and mortality. Although patients with atrial fibrillation (AF) often have kidney dysfunction, less is known about the association between AF and kidney function. We sought to assess changes in kidney function after catheter ablation of AF. Methods and Results—Patients who underwent catheter ablation of AF were recruited...
