Does preprocedural atrial fibrillation compared to sinus rhythm worsen clinical outcomes in patients with significant mitral stenosis undergoing percutaneous mitral valvuloplasty?
Preprocedural atrial fibrillation is associated with worse symptoms and higher event rates after successful percutaneous mitral valvuloplasty, suggesting the procedure should be considered before AF onset.
