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. This procedure was performed in patients with symptomatic arrhythmia refractory to antiarrhythmic therapy. Results. Data were collected from 123 patients (median age: 46 years, 64.2% male), who had a median time of illness of 6 years. Among the arrhythmias treated, 19% had atrial fibrillation, 17.5% atrial tachycardia, 17.5% idiopathic ventricular arrhythmias, 16.6% Wolf Parkinson White syndrome / Atrioventricular reentrant tachycardia, 11.1% ventricular arrhythmias of the His-Purkinje conduction system, 9.5% sca...

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. Results. Fifty-two patients with idiopathic ventricular arrhythmias were included (34 underwent 3D ablation, and 18 underwent antiarrhythmic therapy only). The percentage of recurrence (14.7% vs. 50%, p=0.01) and adverse effects (0% vs. 22.2%, p=0.011) were lower in the 3D ablation group compared to the antiarrhythmic group.

Focal atrial tachycardia is a rare type of supraventricular tachyarrhythmia, generally present in young people, and is a rare cause of tachycardiomyopathy (10%). We present a clinical case of tachycardiomyopathy in a 30-year-old man, without comorbidities, who was diagnosed with incessant focal atrial tachycardia, refractory to medical therapy, and electrical cardioversion. Succesful endocardial ablation was performed,  and in outpatient follow-up at 6 months, he showed a recovery of the left ventricular ejection fraction and reduction of the left chambers to normal ranges, with progressive decrease of dyspnea.

La taquicardia atrial focal es un tipo de taquiarritmia supraventricular poco prevalente, generalmente presente en jóvenes, y constituye una causa rara de taquicardiomiopatía (10%). Presentamos un caso clínico de taquicardiomiopatía en un varón de 30 años, sin comorbilidades, que fue diagnosticado de taquicardia atrial focal incesante, refractaria a terapia médica y cardioversión eléctrica, por lo que se realizó ablación endocárdica, la misma que fue exitosa y en seguimiento ambulatorio a los 6 meses evidenció una recuperación de la fracción de eyección del ventrículo izquierdo y reducción de cavidades izquierdas a rangos normales, con disminución progresiva de disnea.

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. This case report highlights the importance of multimodality imaging to achieve successful and effective transseptal puncture for atrial fibrillation ablation in patients with interatrial septal occlusion devices.

Los dispositivos de oclusión del septo interatrial dificultan el abordaje transeptal para la ablación de la fibrilación auricular, por lo que es necesario contar con métodos de imagen que guíen con seguridad la punción transeptal, como la ecocardiografía intracardíaca (EIC). Se describe el caso de un paciente de 49 años con fibrilación auricular paroxística sintomática, refractaria a fármacos antiarrítmicos, portador de un dispositivo de oclusión del septo interatrial, con intento previo de ablación fallido. La ablación de la fibrilación auricular se realizó con el sistema de mapeo 3D Carto V7, la punción transeptal fue guiada por EIC y el procedimiento fue exitoso. Este reporte de caso resalta la importancia de la multimodalidad en imágenes, con el fin de se logre una punción transeptal exitosa y eficaz para llevar a cabo la ablación de fibrilación auricular en p...

We present the case of a patient with Andersen-Tawil syndrome (ATS), a rare genetic disorder characterized by the presence of ventricular arrhythmias, skeletal dysmorphic features, and periodic muscle paralysis,. The diagnosis was delayed due to the non-simultaneity of symptom presentation. The report highlights the importance of investigating neurological symptoms in the presence of ventricular arrhythmias of unclear origin or cardiac symptoms in patients with periodic paralysis. The diagnosis was confirmed by the identification of a mutation in the KCNJ2 gene (c.224C>T(p.Thr75Met)); this specific mutation has not been reported in the gnomAD database, suggesting a minor allele frequency (MAF) of less than 1%. The patient is currently managed pharmacologically with a betablocker and remains free of arrhythmias.

We present the case of a 51-year-old male with non-ischemic dilated cardiomyopathy and complete atrioventricular block, who was previously implanted with a cardiac resynchronization therapy defibrillator. The patient developed signs of pocket infection with a high risk of extrusion. Partial system extraction was performed, followed by 14 days of intravenous antibiotic therapy. Due to a history of ventricular fibrillation and permanent pacing dependency, and in the absence of viable transvenous access, a sequential implantation strategy was adopted using a leadless pacemaker (Micra AV, Medtronic) and a subcutaneous implantable cardioverter-defibrillator (EMBLEM, Boston Scientific). Both procedures were completed without complications, and the patient showed favorable recovery, with effective pacing, no arrhythmic recurrences, and no signs of infection at the six-month follow-up. This case...
