[Case report: ablation of atrial fibrillation in patient with an interatrial septal oclussion device].

Interatrial septal occlusion devices hinder the transseptal approach for atrial fibrillation ablation, making it necessary to have imaging methods that safely guide transseptal puncture, such as intracardiac echocardiography (ICE). We describe the case of a 49-year-old patient with symptomatic paroxysmal atrial fibrillation, refractory to antiarrhythmic drugs, wearing an interatrial septal occlusion device, with a previous unsuccessful ablation attempt. Atrial fibrillation ablation was performed using the Carto V7 3D mapping system, the transseptal puncture was guided by ICE, and the procedure was successful.

[Quality of life in patients with idiopathic ventricular arrhythmias treated at the Instituto Nacional Cardiovascular - INCOR].

Objective: To describe the quality of life in patients with idiopathic ventricular arrhythmias treated at the Instituto Nacional Cardiovascular INCOR in Lima -Peru.

Materials And Methods: . Analytical and cross-sectional study of patients with idiopathic ventricular arrhythmias treated by 3D ablation or antiarrhythmic therapy between July 2017 and December 2019 to whom the SF-36 health questionnaire was applied to assess quality of life related to health.

[Ablation of cardiac arrhythmias using a three-dimensional electro-anatomical mapping system in the Instituto Nacional Cardiovascular - INCOR].

Objective: To describe the initial experience in ablation of cardiac arrhythmias using 3D mapping at the Instituto Nacional Cardiovascular INCOR (Lima, Peru).

Methods: A retrospective descriptive study was carried out. During February 2020, data was collected from the medical records of all patients in whom ablation was performed using 3D mapping from July 2017 to December 2019.
