Background: Chagas cardiomyopathy (CCM) is increasingly prevalent in developed countries due to migration from endemic areas. Accurate risk stratification is crucial due to the variable clinical course of CCM.
Objective: To analyze the association between Rassi score progression and electrophysiology study (EPS) changes in CCM patients.
There is a gap between high-income countries and others in terms of access to medical cardiac devices, such as pacemakers and implantable cardioverter defibrillators. Costs are one of the main barriers to the use of cardiac devices in these countries. There are international initiatives that aim to reduce the gap.

Article Synopsis
- Atrial tachycardia (AT) ablation near the His-Bundle is risky due to potential AV block, leading researchers to explore catheter positioning on the non-coronary cusp (NCC) as a safer alternative for treatment.
- This study reviewed ten patients with confirmed para-Hisian focal AT, finding that RF delivery at NCC effectively interrupted tachycardia without causing complications or recurrence during a follow-up period of 30 months.
- The results suggest that using the NCC for catheter-based treatment of para-Hisian AT is both safe and effective, providing a promising strategy for managing this complex type of arrhythmia.
Use of intracardiac echocardiography in the electrophysiology laboratory.

The intracardiac echocardiography (ICE) offers a detailed visualization of the cardiac structures, in association with hemodynamic information, allowing the precise and real-time positioning of the catheters, decreasing the time of exposure to fluoroscopy and the monitoring of acute complications during the electrophysiological procedure (i.e., formation of thrombi, pericardial effusion, cardiac tamponade), Consequently, its use has progressively increased, mainly in the ablation of atrial fibrillation and ventricular arrhythmias.

Objective: To evaluate the reproducibility of the surgical technique, its safety and the initial outcome of the video-assisted surgery for the isolated atrial fibrillation ablation with bipolar radiofrequency.
Methods: Ten patients (90% men) with symptomatic atrial fibrillation (50% paroxystic type) that was refractory to drug therapy, with no heart disease that required concomitant surgical treatment, were submitted to arrhythmia ablation guided by thoracoscopy from May 2007 to May 2008.
