Case ReportsAtrial tachycardia originating from the hepatic segment of inferior vena cava in interruption of inferior vena cava with azygos continuation.
Interruption of inferior vena cava (IVC) with azygos continuation is a rare venous anomaly, and arrhythmogenic IVC is also rarely reported. Arrhythmogenicity of the hepatic segment of IVC in interruption of IVC has never been reported. We describe the case of a 37-year-old female with interrupted left IVC with azygos continuation to right superior vena cava and atrial tachycardia originating from the hepatic segment of IVC.

Differences in intraprocedural ACTs with standardized heparin dosing during catheter ablation for atrial fibrillation in patients treated with dabigatran vs. patients on uninterrupted warfarin.
Effective intraprocedural anticoagulation for catheter ablation for atrial fibrillation is critical to minimize the risk of cerebral thromboembolism. The effect of dabigatran on anticoagulation with heparin during the procedure is unknown. This study compares heparin anticoagulation in patients treated with dabigatran vs. patients on uninterrupted warfarin. ⋯ A standard intraprocedural heparin protocol results in delayed and lower levels of anticoagulation as measured by the ACT for patients treated with dabigatran compared with those on uninterrupted warfarin.

Comparative StudyA comparison of bleeding complications post-ablation between warfarin and dabigatran.
Although warfarin has traditionally been used for reducing risk of stroke in patients with atrial fibrillation, over the past year, the direct thrombin inhibitor dabigatran has become an accepted alternative. No study has conclusively investigated bleeding risks of patients treated with dabigatran immediately following radiofrequency catheter ablation (RFCA) procedures. ⋯ In our cohort, bleeding-related complications 48 h and 1 week post-ablation were similar for warfarin and dabigatran. Dabigatran is associated with more intraprocedural variability in ACT than warfarin.
