Background: The guidelines recommend anticoagulation management with uninterrupted warfarin or direct thrombin inhibitors (DTIs) during the atrial fibrillation (AF) ablation periprocedural period.
Objectives: To clarify the Japanese real-world latest periprocedural anticoagulation management during AF ablation.
Methods: This multicenter observational study included 6232 consecutive AF patients (68.
Article Synopsis
- A study evaluated the safety of four new radiofrequency ablation catheters used for treating atrial fibrillation (AF), analyzing 3,957 procedures to identify outcomes and procedure times.
- The results showed that while most catheters achieved a 99.5% success rate in isolating pulmonary veins, differences emerged in procedure duration and complications, with QDOT Micro and THERMOCOOL SMARTTOUCH SF demonstrating shorter fluoroscopic times and lower rates of cardiac tamponade compared to TactiFlex and TactiCath.
- Findings suggest that the type of catheter and mapping system used impacts both safety outcomes and procedural efficiency in real-world applications, with TactiFlex exhibiting the highest risk for complications like cardiac tamponade.
Article Synopsis
- The study compared the efficacy and safety of two cryoballoon systems used for pulmonary vein isolation in patients with atrial fibrillation, involving 2,555 subjects across 19 centers over nearly two years.
- Results showed that the newer POLARx cryoballoon had a lower touch-up ablation rate compared to the conventional Arctic Front Advance cryoballoon, but also a higher incidence of right phrenic nerve injury (PNI).
- Specifically, PNI occurred more frequently with POLARx (3.8%) compared to AFA (1.3%), and recovery from PNI was faster using AFA-CB.
Background: Contrast-enhanced computed tomography (CT) is commonly used to diagnose pulmonary embolism (PE). However, a history of iodine contrast allergy presents a dilemma in the management of patients with PE. As an alternative approach, X-ray fluoroscopic video analysis has been recently reported to be useful in diagnosing PE.

Case Summary: We report a case of a 51-year-old woman who was brought to our hospital unconscious in an ambulance. Cardiac tamponade caused by the rupture of an aneurismal coronary-pulmonary artery fistula (CPAF) was detected by contrast-enhanced computed tomography and confirmed by invasive coronary angiography.
