Liu M, Mei K, Liu X, et al. - Given that there is a lack of clarity regarding the link of BMI and procedure‐related factors in patients with atrial fibrillation (AF) following radiofrequency ablation (RFA), researchers investigated whether BMI is related to increased the radiation dose, procedure duration, and procedural complications. They explored PubMed, Embase, and the Cochrane Library database to identify prospective investigations evaluating BMI and procedure duration, radiation dose, and procedural complications among patients with AF following RFA. This analysis involved 10 studies including 14,735 participants receiving RFA. On the basis of available evidence, experts first demonstrated that the procedure duration was significantly increased as well as a larger radiation dose was received in patients with overweight/obesity undergoing RFA vs patients with normal BMI; however, patients with overweight/obesity vs those with normal BMI did not differ significantly in terms of procedural complications.
