Key result
Intraoperative radiofrequency microbipolar coagulation during valve surgery restored normal sinus rhythm in 80% of survivors, compared to 4.3% in a historical cohort undergoing valve surgery alone.
Why the study?
Does intraoperative radiofrequency microbipolar coagulation improve conversion to normal sinus rhythm in patients with atrial fibrillation undergoing rheumatic valve surgery compared to valve surgery alone?
Cohort (n=44)
Does intraoperative radiofrequency microbipolar coagulation improve conversion to normal sinus rhythm in patients with atrial fibrillation undergoing rheumatic valve surgery compared to valve surgery alone?
Absolute Event Rate: 80% vs 4.3%
Intraoperative radiofrequency microbipolar coagulation during rheumatic valve surgery effectively restores normal sinus rhythm in patients with atrial fibrillation while shortening procedure time compared to the traditional Cox's maze procedure.
No takes yet. Share an insight, caveat, or question.
May support adjunctive radiofrequency microbipolar coagulation for AF in rheumatic valve surgery; leaves open randomized confirmation of benefit.
Ardan Patwardhan (1997) conducted a cohort in Atrial fibrillation and rheumatic valvular disease (n=44). Radiofrequency microbipolar coagulation maze vs. Corrective valve surgery alone was evaluated on Conversion to normal sinus rhythm. Intraoperative radiofrequency microbipolar coagulation during valve surgery restored normal sinus rhythm in 80% of survivors, compared to 4.3% in a historical cohort undergoing valve surgery alone.
