Non-fluoroscopic catheter ablation: A randomized trial.

Leonardo Martins Pires, Tiago Luiz Luz Leiria, Marcelo Lapa Kruse, Gustavo Glotz de Lima,

BACKGROUND:Catheter ablation provides curative treatment for tachyarrhythmias. Fluoroscopy, the method used for this, presents several risks. The electroanatomical mapping (MEA) presents a three-dimensional image without using X-rays, and may be adjunct to fluoroscopy. OBJECTIVES:We evaluated the possibility of performing catheter ablation with the exclusive use of electroanatomical mapping (MEA), dispensing ... Read more >>

Coronary sinus cannulation predicts atrioventricular nodal reentry as mechanism of supraventricular tachycardia.

Tiago Luiz Luz Leiria, Mauricio Branchi, Roberto Tofani Sant'anna, Eduardo Dytz Almeida, Leonardo Martins Pires, Marcelo Lapa Kruse, Vidal Essebag, Marco Aurélio Lumertz Saffi, Gustavo Glotz de Lima,

INTRODUCTION:Common clinical teaching, for invasive electrophysiology, is that if the first year fellow cannulates the coronary sinus (CS) in his first attempt, the arrhythmia is more likely to be atrioventricular nodal reentry tachycardia (AVNRT). This general perception has not yet been clinically tested. We evaluated this theory in prospective patients ... Read more >>

Cohort of Patients Referred for Brugada Syndrome Investigation in an Electrophysiology Service - 19-Year Registry.

Stefan Warpechowski Neto, Tiago Luiz Luz Leiria, Laura Lessa Gaudie Ley, Antonio Lessa Gaudie Ley, Luiza Zwan Dutra, Leonardo Martins Pires, Marcelo Lapa Kruse, Gustavo Glotz de Lima,

BACKGROUND:Brugada syndrome (SBr) is an arrhythmic condition characterized by ST-T segment abnormalities in the right precordial leads associated with a high risk of ventricular arrhythmias and sudden death. Local data regarding the clinical characteristics of patients with a typical electrocardiographic (ECG) pattern undergoing electrophysiological study are scarce. OBJECTIVE:To evaluate patients ...

Uninterrupted Use of Oral Anticoagulants for the Ablation of Atrial Flutter: A Single Center Cohort of 154 Patients.

Tiago Luiz Luz Leiria, Alexandre Kreling Medeiros, Eduardo Dytz Almeida, Antonio Lessa Gaudie Ley, Catarine Benta Lopes Dos Santos, Roberto Toffani Sant'Anna, Marcelo Lapa Kruse, Leonardo Martins Pires, Gustavo Glotz de Lima,

BACKGROUND:The uninterrupted use of oral anticoagulation (OAC) with vitamin K antagonists (VKAs) for electrophysiology procedures has been more and more recommended. The clinical practice in our service recommends the continuous use of these drugs for atrial flutter ablation. There is little evidence as to the uninterrupted use of non-vitamin K ... Read more >>

CHA2 DS2 VASc Score as a Predictor of Cardiovascular Events in Ambulatory Patients without Atrial Fibrillation.

Gustavo Freb Polenz, Tiago Luiz Luz Leiria, Vidal Essebag, Marcelo Lapa Kruse, Leonardo Martins Pires, Thaize Brisolara Nogueira, Raphael Boesche Guimarães, Roberto Tofani Santanna, Gustavo Glotz DE Lima,

New evidence suggests that the CHA(2)DS(2)VASc (congestive heart failure, hypertension [HTN], age, diabetes, stroke, vascular disease, and female gender) score may be a reliable tool to predict the risk of thromboembolic events in patients without documented atrial fibrillation (AF).We performed a prospective cohort study of outpatients without AF or flutter, ...

Clinical Differences between Subtypes of Atrial Fibrillation and Flutter: Cross-Sectional Registry of 407 Patients.

Eduardo Dytz Almeida, Raphael Boesche Guimarães, Laura Siga Stephan, Alexandre Kreling Medeiros, Katia Foltz, Roberto Tofani Santanna, Leonardo Martins Pires, Marcelo Lapa Kruse, Gustavo Glotz de Lima, Tiago Luiz Luz Leiria,

Atrial fibrillation and atrial flutter account for one third of hospitalizations due to arrhythmias, determining great social and economic impacts. In Brazil, data on hospital care of these patients is scarce.To investigate the arrhythmia subtype of atrial fibrillation and flutter patients in the emergency setting and compare the clinical profile, ...

Electrophysiological studies and radiofrequency ablations in children and adolescents with arrhythmia.

Mariana Fernandez Simão, Matheus Nardi Rios, Tiago Luiz Luz Leiria, Marcelo Lapa Kruse, Leonardo Martins Pires, Roberto Tofani SantAnna, Gustavo Glotz de Lima,

BACKGROUND: Radiofrequency ablation is the standard non-pharmacological treatment for arrhythmias in pediatric patients. However, arrhythmias and their associated causes have particular features in this population. OBJECTIVE: To analyze the epidemiological characteristics and findings of electrophysiological diagnostic studies and radiofrequency ablations in pediatric patients referred to the Electrophysiology Unit at Instituto ...

Supraventricular tachycardia and syncope during pregnancy: A case for catheter ablation without fluoroscopy.

Tiago Luiz Luz Leiria, Leonardo Martins Pires, Marcelo Lapa Kruse, Gustavo Glotz de Lima,

Arrhythmias during pregnancy pose a dilemma for the treating physician. Most antiarrhythmic drugs are classified as category C in the FDA labeling system during pregnancy. We describe the case of a pregnant woman who presented syncope due to drug-refractory supraventricular tachycardia who underwent catheter ablation without the use of fluoroscopy. ... Read more >>

Relationship between silent atrial fibrillation and the maximum heart rate in the 24-hour Holter: cross-sectional study.

Marcelo Lapa Kruse, José Cláudio Lupi Kruse, Tiago Luiz Luz Leiria, Leonardo Martins Pires, Caroline Saltz Gensas, Daniel Garcia Gomes, Douglas Boris, Augusto Mantovani, Gustavo Glotz de Lima,

CONTEXT AND OBJECTIVE: Occurrences of asymptomatic atrial fibrillation (AF) are common. It is important to identify AF because it increases morbidity and mortality. 24-hour Holter has been used to detect paroxysmal AF (PAF). The objective of this study was to investigate the relationship between occurrence of PAF in 24-hour Holter ... Read more >>

Risk of ionizing radiation in women of childbearing age undergoing radiofrequency ablation.

Gustavo Glotz de Lima, Daniel Garcia Gomes, Caroline Saltz Gensas, Mariana Fernandez Simão, Matheus N Rios, Leonardo Martins Pires, Marcelo Lapa Kruse, Tiago Luiz Luz Leiria,

BACKGROUND: The International Commission of Radiology recommends a pregnancy screening test to all female patients of childbearing age who will undergo a radiological study. Radiation is known to be teratogenic and its effect is cumulative. The teratogenic potential starts at doses close to those used during these procedures. The prevalence ... Read more >>

Catheter ablation of arrhythmias exclusively using electroanatomic mapping: a series of cases.

Leonardo Martins Pires, Tiago Luiz Luz Leiria, Marcelo Lapa Kruse, Rafael Ronsoni, Caroline Saltz Gensas, Gustavo Glotz de Lima,

BACKGROUND: Catheter ablation is a treatment that can cure various cardiac arrhythmias. Fluoroscopy is used to locate and direct catheters to areas that cause arrhythmias. However, fluoroscopy has several risks. Electroanatomic mapping (EAM) facilitates three-dimensional imaging without X-rays, which reduces risks associated with fluoroscopy. OBJECTIVE: We describe a series of ... Read more >>

Brugada syndrome after using cold medicine: is there any relation?

Tiago Luiz Luz Leiria, Augusto Mantovani, Rafael de March Ronsoni, Leonardo Martins Pires, Marcelo Lapa Kruse, Gustavo Glotz de Lima,

Brugada syndrome (BrS) is associated with increased risk of ventricular arrhythmias and sudden death. Some drugs can trigger the electrocardiographic and arrhythmic manifestations of this syndrome. Cold medicines for symptom relief are sold without prescription in Brazil and most contain antihistamines and adrenergic agonists. We report a case of BrS ... Read more >>
