Ablação por Cateter de Taquicardia Atrial Focal com Ativação Precoce Próxima ao...
Chokr,Muhieddine; Moura,Lucas G. de; Sousa,Italo Bruno dos Santos; Pisani,Cristiano Faria; Hardy,Carina Abigail; Melo,Sissy Lara deResumo Fundamento A ablação da taquicardia atrial (TA) com local de ativação mais precoce próxima ao feixe de His é um desafio, devido ao risco de bloqueio de AV completo por sua proximidade ao sistema de His-Purkinje (SHP). Uma alternativa para minimizar esse risco é posicionar o cateter na cúspide não coronária (CNC), que é anatomicamente contígua à região para-Hissiana. Objetivos O objetivo deste estudo foi ...
Peculiaridade dos Pacientes com Arritmias Hereditárias na Pandemia pela COVID-19
Sacilotto,Luciana; Olivetti,Natalia Quintella Sangiorgi; Pisani,Cristiano Faria; Wu,Tan Chen; Hajjar,Ludhmila Abrahão; Melo,Sissy Lara deResumo Desde dezembro de 2019, observamos o rápido avanço da síndrome respiratória aguda grave causada pelo coronavírus 2019 (SARS-CoV-2). O impacto da evolução clínica de uma infecção respiratória é pouco conhecido em pacientes portadores de arritmias hereditárias, devido à baixa prevalência dessas doenças. Os pacientes que apresentam quadros infecciosos podem exacerbar arritmias primárias ocultas ou bem contr...
Carotid Sinus Massage in Syncope Evaluation: A Nonspecific and Dubious Diagnost...
Wu,Tan Chen; Hachul,Denise T.; Darrieux,Francisco Carlos da Costa; Scanavacca,Maurício I.Abstract Background: Carotid sinus hypersensitivity (CSH) is a frequent finding in the evaluation of syncope. However, its significance in the clinical setting is still dubious. A new criterion was proposed by Solari et al. with a symptomatic systolic blood pressure (SBP) cut-off value of ≤ 85 mmHg to refine the vasodepressor (VD) response diagnosis. Objective: To determine and compare the response to carotid s...
Late Outcome of a Randomized Study on Oral Magnesium for Premature Complexes
Falco,Cristina Nádja M. Lima De; Darrieux,Francisco Carlos da Costa; Grupi,Cesar; Sacilotto,Luciana; Pisani,Cristiano F.; Lara,Sissy; Ramires,José A. F.Background:Ventricular and supraventricular premature complexes (PC) are frequent and usually symptomatic. According to a previous study, magnesium pidolate (MgP) administration to symptomatic patients can improve the PC density and symptoms.Objective:To assess the late follow-up of that clinical intervention in patients treated with MgP or placebo.Methods:In the first phase of the study, 90 symptomatic and con...
Comparison between tilt-table testing results performed during different period...
Wu,Tan Chen; Hachul,Denise; Scanavacca,Mauricio; Sosa,EduardoOBJECTIVE: To evaluate the influences of circadian variations on tilt-table testing (TTT) results by comparing the positivity rate of the test performed during the morning with that of the test performed in the afternoon and to evaluate the reproducibility of the results in different periods of the day. METHODS: One hundred twenty-three patients with recurrent unexplained syncope or near-syncope referred for TT...
Diagnostic value of the tilt-table test for the assessment of syncope in childr...
Wu,Tan Chen; Hachul,Denise; Scanavacca,Mauricio; Sosa,EduardoOBJECTIVE - To assess the diagnostic value, the characteristics, and feasibility of tilt-table testing in children and adolescents. METHODS - From August 1991 to June 1997, we retrospectively assessed 94 patients under the age of 18 years who had a history of recurring syncope and presyncope of unknown origin and who were referred for tilt-table testing. These patients were divided into 2 groups: group I (child...
