Clinical effectiveness and efficiency of a new steerable sheath technology for radiofrequency ablation in Chinese patients with atrial fibrillation: a retrospective comparative cohort study

Steerable versus nonsteerable sheath technology in atrial fibrillation ablation: a prospective, randomized study.

BACKGROUND Steerable sheath technology is designed to facilitate catheter access, stability, and tissue contact in target sites of atrial fibrillation (AF) catheter ablation. We hypothesized that rhythm control after interventional AF treatment is more successful using a steerable as compared with a nonsteerable sheath access. METHODS AND RESULTS One hundred thirty patients with paroxysmal or...

radiofrequency atrial fibrillation ablation technique in patients with mitral valve surgery and left atrial reduction procedures

background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...

a comparative study of the relationship between self-, peer-, and teacher-assessments in productive skills

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...

Radiofrequency ablation for atrial fibrillation

Cost-effectiveness of radiofrequency catheter ablation for atrial fibrillation.

OBJECTIVES We sought to compare the cost-effectiveness of left atrial catheter ablation (LACA), amiodarone, and rate control therapy in the management of atrial fibrillation (AF). BACKGROUND Left atrial catheter ablation has been performed to eliminate AF, but its cost-effectiveness is unknown. METHODS We developed a decision-analytic model to evaluate the cost-effectiveness of LACA in 55- ...
