Electrophysiology lab efficiency using cryoballoon for pulmonary vein isolation in Latin America: A sub-analysis of the Cryo Global Registry Study.

Objective: Cryoballoon ablation for pulmonary vein isolation is a time-efficient procedure that can alleviate stress on electrophysiology lab resources. This analysis modeled the impact of cryoballoon ablation on electrophysiology lab operation using data from Latin America.

Methods: Data from centers in Argentina, Mexico, Colombia, and Chile of the were used as inputs for an electrophysiology lab efficiency simulation model.

We present the case of a 75-year-old male with history of 5 months of right submaxillary tumor, with no clear etiology, who consulted for episodes of syncope preceded by dyspnea and sudden onset of profuse sweating. During his stay at the hospital, electrocardiographic records showed more than 3-second-long pauses after head movements, with a sensation of imminent loss of consciousness associated. A temporary pacemaker was required.

Catheter ablation of ventricular tachycardia in patients with electrical storm, with a special focus on patients with Chagas disease.

Background: There are few reports on the benefits of catheter ablation (CA) in patients with electrical storm (ES). None of these publications included patients with Chagas disease (ChD). Our aims are to analyze (1) all the cases of ES treated with CA and (2) the subgroup of patients with ChD.
