Why the study?
Does complex LAA morphology increase the risk of LAA thrombus in patients with atrial fibrillation?
Does complex LAA morphology increase the risk of LAA thrombus in patients with atrial fibrillation?
Complex LAA morphology with an increased number of lobes is an independent risk factor for LAA thrombus formation in patients with atrial fibrillation.
May refine AF thrombus risk assessment via LAA lobe count; hypothesis-generating pending prospective validation.
Complex LAA morphology characterized by an increased number of LAA lobes was associated with the presence of LAA thrombus independently of clinical risk and blood stasis. This study suggests that LAA morphology might be a congenital risk factor for LAA thrombus formation in patients with AF.
