New analysis links combined heart procedures to more rhythm recurrences

This human-focused meta-analysis compared catheter ablation alone with catheter ablation combined with left atrial appendage closure in 3,274 people with atrial fibrillation across 14 studies. The combined approach was associated with more recurrent abnormal heart rhythms and a slightly longer procedure time, while one serious fluid-related complication did not differ significantly between groups. Because the underlying studies were not described in full and randomized trials are still needed, the results are not conclusive.

Review links combined heart procedures to fewer clots but more drainage-requiring fluid

This human-health meta-analysis compared left atrial appendage closure alone with the same procedure combined with pulmonary vein isolation in people with atrial fibrillation. The combined approach was associated with fewer systemic thromboembolisms during follow-up, but more pericardial effusions requiring drainage around the procedure. Because the review drew largely on heterogeneous observational data, the findings show associations rather than confirmed effects caused by the combined procedure.
