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.
