Abstract: Mitral regurgitation is recognized as the most common valvulopathy among cardiac valve disorders, with causes divided into primary and secondary components. Traditionally, the secondary component has been associated with the dilation of the ventricular cavity and ring; however, recent interpretations also include the dilation of the left atrium as a significant factor, especially when the dimensions of the left ventricular cavity are preserved. This new perspective has led to a reinterpretation of the pathogenesis, diagnosis, and treatment of atrial functional mitral regurgitation. The research focused on a case study of patients with this condition and atrial fibrillation, who were treated through catheter ablation. This approach was supported by an exhaustive bibliographic review conducted in databases such as MEDLINE via PUBMED. The findings reveal that atrial functional mitral regurgitation, now recognized as a distinct pathological entity, challenges the previous belief that only the dilation of the left ventricle and mitral ring were the causes of the disease. Furthermore, it was determined that catheter ablation is effective not only for restoring sinus rhythm but also for improving valvular function and quality of life in patients with this condition and atrial fibrillation
