    Effects of anthracycline, cyclophosphamide and taxane chemotherapy on QTc measurements in patients with breast cancer
    (2018) VERONESE, Pedro; HACHUL, Denise Tessariol; SCANAVACCA, Mauricio Ibrahim; HAJJAR, Ludhmila Abrahao; WU, Tan Chen; SACILOTTO, Luciana; VERONESE, Carolina; DARRIEUX, Francisco Carlos da Costa
    Aim Acute and subacute cardiotoxicity are characterized by prolongation of the corrected QT interval (QTc) and other measures derived from the QTc interval, such as QTc dispersion (QTdc) and transmural dispersion of repolarization (DTpTe). Although anthracyclines prolong the QTc interval, it is unclear whether breast cancer patients who undergo the ACT chemotherapy regimen of anthracycline (doxorubicin: A), cyclophosphamide (C) and taxane (T) may present with QTc, QTdc and DTpTe prolongation. Methods Twenty-three consecutive patients with breast cancer were followed prospectively during ACT chemotherapy and were analyzed according to their QT measurements. QTc, QTdc and DTpTe measurements were determined by a 12-lead electrocardiogram (EKG) prior to chemotherapy (baseline), immediately after the first phase of anthracycline and cyclophosphamide (AC) treatment, and immediately after T treatment. Serum troponin and B-type natriuretic peptide (BNP) levels were also measured. Results Compared to baseline values, the QTc interval was significantly prolonged after the AC phase (439.7 +/- 33.2 ms vs. 472.5 +/- 36.3 ms, p = 0.001) and after T treatment (439.7 +/- 33.2 ms vs. 467.9 +/- 42.6 ms, p < 0.001). Troponin levels were elevated after the AC phase (23.0 pg/mL [min-max: 6.0-85.0] vs. 6.0 pg/mL [min-max: 6.0-22.0], p < 0.001) and after T treatment (25.0 pg/mL [min-max: 6.0-80.0] vs. 6.0 pg/mL [min-max: 6.0-22.0], p < 0.001) compared to baseline values. Conclusion In this prospective study of patients with non-metastatic breast cancer who underwent ACT chemotherapy, significant QTc prolongation and an elevation in serum troponin levels were observed.

    Age is associated with time in therapeutic range for warfarin therapy in patients with atrial fibrillation
    (2016) MARCATTO, Leiliane Rodrigues; SACILOTTO, Luciana; DARRIEUX, Francisco Carlos da Costa; HACHUL, Denise Tessariol; SCANAVACCA, Mauricio Ibrahim; KRIEGER, Jose Eduardo; PEREIRA, Alexandre Costa; SANTOS, Paulo Caleb Junior Lima
    Background: Warfarin is the most prescribed oral anticoagulant used for preventing stroke in patients with atrial fibrillation. Time in the therapeutic range (TTR) has been accepted as the best method to evaluate the quality of warfarin therapy. The main aim of the present study was to evaluate the impact of variables on the time in the therapeutic range for warfarin therapy in patients with atrial fibrillation from a referral cardiovascular hospital. Methods: This retrospective study included 443 patients were included (190 patients with age < 65 years and 253 patients with age >= 65 years) from 2011 to 2014 and TTR was computed according to Rosendaal's method. Results: Patients with age >= 65 years had higher TTR value (67+/-22%) compared with patients with < 65 years (60+/-24%) (p = 0.004). In a linear regression model, only age >= 65 years emerged as a significant predictor of greater TTR values. In multivariate logistic regression model, the variable age = 65 years was associated with higher OR for having a TTR higher than the median value (OR = 2.17, p < 0.001). Conclusion: We suggest that the age influenced TTR through greater drug adherence. Strategies for increasing drug adherence might improve quality of warfarin anticoagulation.

    Compound Heterozygous SCN5A Mutations in a Toddler - Are they Associated with a More Severe Phenotype?
    (2017) SACILOTTO, Luciana; EPIFANIO, Hindalis Ballesteros; DARRIEUX, Francisco Carlos da Costa; WULKAN, Fanny; OLIVEIRA, Theo Gremen Mimary; HACHUL, Denise Tessariol; PEREIRA, Alexandre da Costa; SCANAVACCA, Mauricio Ibrahim
    Compound heterozygosity has been described in inherited arrhythmias, and usually associated with a more severe phenotype. Reports of this occurrence in Brugada syndrome patients are still rare. We report a study of genotype-phenotype correlation after the identification of new variants by genetic testing. We describe the case of an affected child with a combination of two different likely pathogenic SCN5A variants, presenting sinus node dysfunction, flutter and atrial fibrillation, prolonged HV interval, spontaneous type 1 Brugada pattern in the prepubescent age and familiar history of sudden death.

    Arterial stiffness and atrial fibrillation: A review
    (2022) LAGE, Joao Gabriel Batista; BORTOLOTTO, Alexandre Lemos; SCANAVACCA, Mauricio Ibrahim; BORTOLOTTO, Luiz Aparecido; DARRIEUX, Francisco Carlos da Costa
    Arterial stiffness has been investigated as part of the physiopathology of arterial hypertension since the 1970s. Its role in increasing the ""pulsatile load"" imposed over the Left Ventricle (LV) has been intensely studied recently and has helped in understanding the mechanisms of Atrial Fibrillation (AF) in hypertensive patients. This paper aims to review the main evidence on this issue and establish possible mechanisms involved in the development of AF in patients with arterial stiffness. A PubMed search was performed, and selected articles were searched for references focusing on this topic. In the long term, lower blood pressure levels allow for arterial wall remodeling, leading to a lower stiffness index. To this day, however, there are no available treatments that directly promote the lowering of arterial wall stiffness. Most classes of anti-hypertensive drugs -with stronger evidence for betablockers and diuretics -could be effective in reducing arterial stiffness. There is strong evidence demonstrating an association between arterial stiffness and AF. New studies focusing on arterial stiffness and pre-fibrillatory stages would strengthen this causality relation.

    Occurrence of recently diagnosed atrial fibrillation in the immediate postoperative period of myocardial revascularization surgery. Although common, a devalued complication
    (2020) PEREIRA, Marcel de Paula; LIMA, Eduardo Gomes; GARZILLO, Cibele Larrosa; BARBOSA, Camila Talita Machado; SAMPAIO, Leon Pablo Cartaxo; DARRIEUX, Francisco Carlos da Costa; SERRANO JR., Carlos Vicente
    Atrial fibrillation (AF) is the most common arrhythmia in the postoperative period of cardiac surgery, with a prevalence between 15-40% after coronary artery bypass surgery (CABG). Several strategies have been tested for the prevention and management of AF postoperatively. Previous studies and analysis of records have shown higher rates of hospitalization and clinical outcomes associated with this entity, including increased mortality in the short- and long-term. This perspective reviews the topic, and offers recommendations for the management of this arrhythmia in the postoperative period of CABG, with a special focus on anticoagulation strategies.

    Catheter Ablation of Focal Atrial Tachycardia with Early Activation Close to the His-Bundle from the Non Coronary Aortic Cusp
    (2021) CHOKR, Muhieddine; MOURA, Lucas G. de; SOUSA, Italo Bruno dos Santos; PISANI, Cristiano Faria; HARDY, Carina Abigail; MELO, Sissy Lara de; PONTE FILHO, Arnobio Dias da; COSTA, Ieda Prata; TAVORA, Ronaldo Vasconcelos; SACILOTTO, Luciana; WU, Tan Chen; DARRIEUX, Francisco Carlos da Costa; HACHUL, Denise Tessariol; AIELLO, Vera; SCANAVACCA, Mauricio
    Background: Atrial tachycardia (AT) ablation with earliest activation site close to the His-Bundle is a challenge due to the risk of complete AV block by its proximity to His-Purkinje system (HPS). An alternative to minimize this risk is to position the catheter on the non-coronary cusp (NCC), which is anatomically contiguous to the para-Hisian region. Objectives: The aim of this study was to perform a literature review and evaluate the electrophysiological characteristics, safety, and success rate of catheter-based radiofrequency (RF) delivery in the NCC for the treatment of para-Hisian AT in a case series. Methods: This study performed a retrospective evaluation of ten patients (Age: 36 +/- 10 y-o) who had been referred for SVT ablation and presented a diagnosis of para-Hisian focal AT confirmed by classical electrophysiological maneuvers. For statistical analysis, a p-value of <0.05 was considered statistically significant. Results: The earliest atrial activation at the His position was 28 +/- 12ms from the P wave and at the NCC was 3 +/- 2ms earlier than His position, without evidence of His potential in all patients. RF was applied on the NCC (4-mm-tip catheter; 30W, 55 degrees C), and the tachycardia was interrupted in 5 +/- 3s with no increase in the PR interval or evidence of junctional rhythm. Electrophysiological tests did not reinduce tachycardia in 9/10 of patients. There were no complications in all procedures. During the 30 +/- 12 months follow-up, no patient presented tachycardia recurrence. Conclusion: The percutaneous treatment of para-Hisian AT through the NCC is an effective and safe strategy, which represents an interesting option for the treatment of this complex arrhythmia.

    Incor Residency Program in Adult Cardiology in 2022: 40 Years Preparing Cardiologists for the Demands in Brazil
    (2022) LOTTENBERG, Marcos Pita; BICHUETTE, Luciana Dornfeld; BORTOLOTTO, Luiz Aparecido; GOWDAK, Luis Henrique Wolff; DARRIEUX, Francisco Carlos da Costa; BINOTTO, Maria Angelica; KALIL FILHO, Roberto; CARAMELLI, Bruno
    Background: Considering demographic data related to the cardiologist's fields of work in Brazil, the administrative board of the InCor medical residency program decided for an update of its curriculum content, to adapt the educational process to the cardiologist's work reality. Objective: This article aimed to describe the recent updates applied to the InCor medical residency program. Methods: In the article, we described the recent updates on the InCor residency program, and compared the current curriculum track with the previous one. We also presented the rationale for these changes, based on the literature on the participation of cardiologists in the labor market. Results: There was a reduction in the working hours of residents in training in the intensive care unit, and an increase in the outpatient activities of primary and secondary prevention. Also, the didactic content was reformulated and became organized by the corresponding division. Conclusion: The update of the curriculum track of the InCor medical residency program was required in order to adapt it to the Brazilian labor market. The commission in charge of this update is aware that this is a dynamic process that may need changes over time.
