Introduction: The reduction of fluoroscopic exposure during catheter ablation of supraventricular arrhythmias is widely adopted by experienced electrophysiology physicians with a relatively short learning curve and is becoming the standard of care in many parts of the world. While observational studies in the United States and some parts of Western Europe have evaluated the minimal fluoroscopic approach, there are scarce real-world data for this technique and the generalizability of outcomes in other economic regions.
Method: The AALARA study is a prospective, observational, multicenter, and multinational open-label study.

Article Synopsis
- The study assessed the effectiveness of a high-density mapping catheter (HD Grid) in performing ablation procedures for patients with persistent atrial fibrillation (PersAF) over a 12-month follow-up.
- A total of 334 participants were involved, with significant differences noted in mapping techniques that affected treatment strategies, leading to a majority receiving successful ablation.
- Ultimately, 82% of subjects remained free from recurrent atrial arrhythmias, indicating both the safety and efficacy of the HD Grid in managing complex heart conditions.

- The study compared the effectiveness of two ablation techniques for treating persistent atrial fibrillation: remote robotic navigation with contact force sensing (RRN/CFS) and manual ablation with CFS.
- Results showed that RRN/CFS had significantly better success rates (64% vs. 36%) and shorter fluoroscopy times compared to manual CFS ablation, while both methods had similar procedure times.
- Overall, combining RRN with CFS leads to higher success rates and efficiency in ablation procedures without increasing complications, suggesting this approach is beneficial for patients with persistent atrial fibrillation.
Background: The PANORAMA study was designed to collect concurrent data on subjects from different worldwide regions implanted with CRM devices.
Methods: In this prospective, multi-center study, we analyzed baseline data on 8586 subjects implanted with CRM devices with no additional selection criteria (66% pacemaker (IPG), 16% implantable cardiac defibrillators (ICD), 17% cardiac resynchronization therapy (CRT) and < 1% Internal Loop Recorder) from 156 hospitals across 6 geographical regions between 2005 and 2011.
Results: Regardless of the device implanted, subjects from the Middle East and India often had more diabetes than other regions.
Catheter ablation of ventricular tachycardia (VT) is demanding and time consuming. Robotically controlled catheter ablation reduces operator fatigue and exposure to X-rays, and provides greater precision and stability of the catheter. A new flexible, integrated robotic sheath and ablation catheter has recently been introduced (Lynx(TM)) and used in atrial ablation procedures.

- The Hansen Robotic system is used for atrial fibrillation ablation but may pose a higher risk of complications due to lack of tactile feedback.
- A survey of 12 centers revealed a 4.7% complication rate and a 67.1% success rate in 1,728 procedures, indicating that higher case volume often leads to better outcomes.
- Low volume centers showed a significant learning curve, with complications decreasing after the first 50 procedures, while higher volume centers maintained a consistent low complication rate.
Background: We report the first single-centre experience in Africa with the Sensei X robotic navigation system in an unselected subset of patients with atrial fibrillation (AF).
Methods: Data were recorded prospectively of all consecutive patients who underwent robotically assisted catheter ablation therapy using the Sensei X robotic navigation system at the Christiaan Barnard Memorial Hospital, Cape Town, South Africa, from July 2009 to July 2010. Outcomes were defined at one and nine months.
