Device-Related Thrombosis in Patients Receiving One-Stop Intervention for Nonvalvular Atrial Fibrillation: A Systemic Review and Meta-Analysis
CLINICAL AND APPLIED THROMBOSIS-HEMOSTASIS(2021)
摘要
This study aimed to assess the incidence, clinical implications, and treatment strategies of device-related thrombus (DRT) following catheter ablation and percutaneous left atrial appendage occlusion combined in one intervention. A meta-analysis of observational studies was conducted to evaluate the incidence rates, treatment strategies, and clinical implications of DRT. A total of 21 studies describing DRT events and 1 case were included in the current study. The 21 included studies comprised 3 multicenter registries and 18 single-center registries, and we also included 1 case report analyzing the characteristics of DRT. The pooled incidence of DRT in one-stop intervention was 18/1,708 (1.2%; range = 0%-7.3%; 95% CI = 0.7%-1.8%; I-2 = 0). Of these DRT events, 56.25% were diagnosed in the first 3 months after the procedure. All cases were diagnosed via trans-esophagus echocardiogram. All of the patients diagnosed with DRT were prescribed anticoagulation treatment, and 63% (12/19) of the events were reported with an outcome of complete thrombus resolution. The duration of anticoagulation treatment varied greatly, from 30 days to 6 months. Unknown clinical events were reported relating to DRT. Device-related thrombus is an uncommon complication of one-stop intervention. It occurs mainly in the early period following the procedure. Anticoagulation appears to be an appropriate treatment method for dissolving occurrences of DRT.
