Journal Articles: Pulmonary vein isolation (PVI) is an effective strategy for patients with paroxysmal atrial fibrillation (AF).1 However, in patients with persistent AF and long-standing persistent AF, PVI is associated with limited success, with patients not responding to PVI.2 Recently, the BELIEF trial (Effect of Empirical Left Atrial Appendage Isolation on Long-term Procedure Outcome in Patients With Persistent or Longstanding Persistent Atrial Fibrillation Undergoing Catheter Ablation) showed that an electric isolation of the left atrial (LA) appendage (LAA) in addition to PVI could increase clinical success.3 Although potentially effective, this strategy causes electromechanical dissociation of the LAA and was assumed to be associated with increased risk for LAA thrombus and thromboembolism.4 We sought to investigate the incidence of LAA thrombus and thromboembolism and the impact of LAA closure on the prevention of thromboembolic events, in addition to the clinical benefit after left atrial appendage isolation (LAAI).
Journal Articles: OBJECTIVES This study compared the efficacy and safety of the VASCADE MVP Venous Vascular Closure System (VVCS) device (Cardiva Medical, Santa Clara, California) to manual compression (MC) for closing multiple access sites after catheter-based electrophysiology procedures. BACKGROUND The The VASCADE MVP VVCS is designed to provide earlier ambulatory hemostasis than MC after catheter-based procedures. METHODS The AMBULATE (A Randomized, Multi-center Trial to Compare Cardiva Mid-Bore (VASCADE MVP) VVCS to Manual Compression in Closure of Multiple Femoral Venous Access Sites in 6 – 12 Fr Sheath Sizes) trial was a multicenter, randomized trial of device closure versus MC in patients who underwent ablation. Outcomes included time to ambulation (TTA), total post-procedure time (TPPT), time to discharge eligibility (TTDe), time to hemostasis (TTH), 30-day major and minor complications, pain medication usage, and patient-reported outcomes. RESULTS A total of 204 patients at 13 sites were randomized to the device arm (100 patients; 369 access sites) or the MC arm (104 patients; 382 access sites). Baseline characteristics were similar between groups. Mean TTA, TPPT, TTDe, and TTH were substantially lower in the device arm (respective decreases of 54%, 54%, 52%, and 55%; all p < 0.0001). Opioid use was reduced by 58% (p ¼ 0.001). There were no major access site complications. Incidence of minor complications was 1.0% for the device arm and 2.4% for the MC arm (p ¼ 0.45). Patient satisfaction scores with duration of and comfort during bedrest were 63% and 36% higher in device group (both p < 0.0001). Satisfaction with bedrest pain was 25% higher (p ¼ 0.001) for the device overall, and 40% higher (p ¼ 0.002) for patients with a previous ablation. CONCLUSIONS Use of the closure device for multiple access ablation procedures resulted in significant reductions in TTA, TPPT, TTH, TTDe, and opioid use, with increased patient satisfaction and no increase in complications.

Care Pathways/CDS: Atrial fibrillation (AF) is the most common cardiac arrhythmia and its prevalence is continuously increasing in the United States, leading to a progressive rise in the number of disease-related emergency department (ED) visits and hospitalizations. Although optimal long-term outpatient management for AF is well defined, the guidelines for optimal ED management of acute AF episodes is less clear. Studies have demonstrated that discharging patients with AF from the ED after acute stabilization is both safe and cost effective; however, the majority of these patients in the United States and in our institution are admitted to the hospital. To improve care of these patients, we established a multidisciplinary collaboration to develop an evidence-based systematic approach for the treatment and management of AF in the ED, that led to the creation of the University of California—Cardioversion, Anticoagulation, Rate Control, Expedited Follow-up/Education Atrial Fibrillation Pathway. Our pathway focuses on the acute stabilization of AF, adherence to best practices for anticoagulation, and reduction in unnecessary admissions through discharge from the ED with expedited outpatient follow-up whenever safe. A novel aspect of our pathway is that it is primarily driven by the ED physicians, while other published protocols primarily involve consulting cardiologists to guide management in the ED. Our protocol is very pertinent considering the current trend toward increased AF prevalence in the United States, coupled with a need for widespread implementation of strategies aimed at improving management of these patients while safely reducing hospital admissions and the economic burden of AF.
