conferenceObject Incidence and Variables Associated With Arrhythmias During Dobutamine-atropine Stress Echocardiography Among Patients With Chagas Disease.(2018) RASSI, Daniela C.; HOTTA, Viviane T.; FURTADO, Rogerio G.; VIEIRA, Marcelo Luiz C.; TURCO, Fabio P.; MELATO, Lucuano H.; DOURADO, Colandy N.; RASSI, Luiz; RASSI, Salvador- Parâmetros Ecocardiográficos e Sobrevida na Cardiopatia Chagásica com Disfunção Sistólica Importante(2014) RASSI, Daniela do Carmo; VIEIRA, Marcelo Luiz Campos; ARRUDA, Ana Lúcia Martins; HOTTA, Viviane Tiemi; FURTADO, Rogério Gomes; RASSI, Danilo Teixeira; RASSI, SalvadorBackground: Echocardiography provides important information on the cardiac evaluation of patients with heart failure. The identification of echocardiographic parameters in severe Chagas heart disease would help implement treatment and assess prognosis. Objective: To correlate echocardiographic parameters with the endpoint cardiovascular mortality in patients with ejection fraction < 35%. Methods: Study with retrospective analysis of pre-specified echocardiographic parameters prospectively collected from 60 patients included in the Multicenter Randomized Trial of Cell Therapy in Patients with Heart Diseases (Estudo Multicêntrico Randomizado de Terapia Celular em Cardiopatias) - Chagas heart disease arm. The following parameters were collected: left ventricular systolic and diastolic diameters and volumes; ejection fraction; left atrial diameter; left atrial volume; indexed left atrial volume; systolic pulmonary artery pressure; integral of the aortic flow velocity; myocardial performance index; rate of increase of left ventricular pressure; isovolumic relaxation time; E, A, Em, Am and Sm wave velocities; E wave deceleration time; E/A and E/Em ratios; and mitral regurgitation. Results: In the mean 24.18-month follow-up, 27 patients died. The mean ejection fraction was 26.6 ± 5.34%. In the multivariate analysis, the parameters ejection fraction (HR = 1.114; p = 0.3704), indexed left atrial volume (HR = 1.033; p < 0.0001) and E/Em ratio (HR = 0.95; p = 0.1261) were excluded. The indexed left atrial volume was an independent predictor in relation to the endpoint, and values > 70.71 mL/m2 were associated with a significant increase in mortality (log rank p < 0.0001). Conclusion: The indexed left atrial volume was the only independent predictor of mortality in this population of Chagasic patients with severe systolic dysfunction.

article 5 Citação(ões) na Scopus Comparação entre a ecocardiografia 2D e 3D na avaliação do remodelamento reverso após a TRC(2011) HOTTA, Viviane Tiemi; MARTINELLI FILHO, Martino; MADY, Charles; MATHIAS JR., Wilson; VIEIRA, Marcelo Luiz CamposBackground: Echocardiography is a useful method for screening and assessing response to cardiac resynchronization therapy (CRT). 3D echocardiography has already established its role in the evaluation of ventricular volumes and ejection fraction (LVEF) with excellent correlation of results when compared with magnetic resonance imaging (MRI). Objective: To compare the evaluation of ventricular volumes (LVDV, LVSV), LVEF, and LV mass before and after CRT by 2D echocardiography and three-dimensional echocardiography. Methods: We evaluated 24 patients with heart failure (HF), functional class (FC) III or IV (NYHA), sinus rhythm QRS >= 120 ms, during an optimized therapy for HF undergoing CRT. We conducted electrocardiogram (ECG), clinical evaluation, 2D and 3D echocardiography before, three and six months after CRT. The comparison between the techniques was performed using Pearson's correlation (r). Results: At baseline, the correlation between methods was 0.96 for evaluation of LVDV, 0.95 for evaluation of LVSV, 0.87 for LVEF and 0.72 for LV mass. After three months of CRT, the correlation between methods for analysis of LVDV was 0.96, 0.95 for LVSV, 0.95 for LVEF, and 0.77 for LV mass. After six months of CRT, the correlation between 2D and 3D echocardiography for analysis of LVDV was 0.98, 0.91 for LVSV, 0.96 for LVEF, and 0.85 for LV mass. Conclusion: This study reported was a reduction of LVDV, LVSV, besides improvement in LVEF after CRT. There was an excellent correlation between the 2D and 3D echocardiography for evaluation of ventricular volumes and LVEF, and a good correlation between methods for evaluation of left ventricular mass before and after CRT. (Arq Bras Cardiol 2011; 97(2) : 111-121)- Incidence and variables associated with arrhythmias during dobutamine-atropine stress echocardiography among patients with Chagas disease(2019) RASSI, Daniela Carmo; HOTTA, Viviane Tiemi; FURTADO, Rogerio Gomes; VIEIRA, Marcelo Luiz Campos; TURCO, Fabio Paula; MELATO, Luciano Henrique; NUNES, Colandy Godoy; JR, Luiz Rassi; RASSI, SalvadorBackground Dobutamine stress echocardiography (DSE) is an important tool in the diagnosis of coronary artery disease. However, there is hesitation in clinical practice for using it in patients with Chagas disease (CD) due to the arrhythmogenic potential of this heart condition. This study aimed to evaluate the incidence and variables associated with arrhythmias during DSE in a population of patients with CD. Methods A population of 205 consecutive patients with CD and suspected coronary heart disease was assessed through a retrospective database analysis. CD was confirmed in all patients by serological testing. Results The mean age of the patients selected was 64 years, and 65.4% of the patients were female. Significant arrhythmias occurred as follows: nonsustained ventricular tachycardia in 7.3% of patients; supraventricular tachycardia and sustained ventricular tachycardia in 1%; and atrial fibrillation in 0.5%. Nonsignificant arrhythmias occurred as follows: premature ventricular contractions in 48% of patients and bigeminy in 4.4%. Values for the wall-motion score index at rest greater than 1.12 and 1.18 were independently correlated with the occurrence of nonsignificant arrhythmias (odds ratio [OR] = 2.90, P < 0.001) and significant arrhythmias (OR = 4.23, P = 0.044), respectively. Conclusion DSE should be considered a safe examination in patients with CD despite the known increased risk of arrhythmias in this group of patients. The occurrence of arrhythmias was low in this study. Abnormal wall-motion score index values at rest were associated with the occurrence of significant and nonsignificant arrhythmias during the test.

Fabio- Deposit Diseases as Differential Diagnosis of Left Ventricular Hypertrophy in Patients with Heart Failure and Preserved Systolic Function(2019) FERNANDES, Fabio; ANTUNES, Murillo Oliveira; HOTTA, Viviane Tiemi; ROCHITTE, Carlos Eduardo; MADY, CharlesHeart failure with preserved systolic function is the main clinical manifestations of patients with ventricular hypertrophy. Conventional treatment is based on the improvement of diastolic dysfunction and congestion. However, no drug has been shown to be effective in the survival of these patients. Thus, it is important to look for the etiology of ventricular hypertrophy with the aim of a treatment directed to the underlying disease.
- Segurança do Ecocardiograma sob Estresse com Dobutamina-Atropina em Pacientes com Doença de Chagas(2017) RASSI, Daniela do Carmo; VIEIRA, Marcelo Luiz Campos; FURTADO, Rogerio Gomes; TURCO, Fabio de Paula; MELATO, Luciano Henrique; HOTTA, Viviane Tiemi; NUNES, Colandy Godoy de Oliveira; RASSI JR., Luiz; RASSI, SalvadorBackground: A few decades ago, patients with Chagas disease were predominantly rural workers, with a low risk profile for obstructive coronary artery disease (CAD). As urbanization has increased, they became exposed to the same risk factors for CAD of uninfected individuals. Dobutamine stress echocardiography (DSE) has proven to be an important tool in CAD diagnosis. Despite being a potentially arrhythmogenic method, it is safe for coronary patients without Chagas disease. For Chagas disease patients, however, the indication of DSE in clinical practice is uncertain, because of the arrhythmogenic potential of that heart disease. Objectives: To assess DSE safety in Chagas disease patients with clinical suspicion of CAD, as well as the incidence of arrhythmias and adverse events during the exam. Methods: Retrospective analysis of a database of patients referred for DSE from May/2012 to February/2015. This study assessed 205 consecutive patients with Chagas disease suspected of having CAD. All of them had their serology for Chagas disease confirmed. Results: Their mean age was 64 +/- 10 years and most patients were females (65.4%). No patient had significant adverse events, such as acute myocardial infarction, ventricular fibrillation, asystole, stroke, cardiac rupture and death. Regarding arrhythmias, ventricular extrasystoles occurred in 48% of patients, and non-sustained ventricular tachycardia in 7.3%. Conclusion: DSE proved to be safe in this population of Chagas disease patients, in which no potentially life-threatening outcome was found.
- Diagnóstico e Tratamento de Complicação Rara após Biópsia Endomiocárdica(2017) HOTTA, Viviane Tiemi; RANGEL, Daniella Diniz do Nascimento; TAVARES, Glaucia Maria Penha; MANGINI, Sandrigo; LEMOS, Pedro A.Endomyocardial biopsy (EBM) is the gold standard method for the diagnosis of rejection after cardiac transplantation. Complications associated with the procedure are rare but can occur in about 8% of the cases. We describe a case of an uncommon complication probably associated with multiple EBMs in a transplanted patient. A 54-year-old male patient underwent orthotopic cardiac transplantation due to idiopathic dilated cardiomyopathy. Over the next ten months, the patient was submitted to eight EMBs and required pulse therapy on two occasions. In the routine outpatient evaluation, continuous systo diastolic murmur was observed in the left lower parasternal border and significant worsening of renal function. A transthoracic echocardiogram was performed, showing high velocity, right-sided apical flow on the color flow mapping and a significant dilation of the anterior descending coronary artery (ADA). The ADA presented significant dilatation with signs of communication with the right ventricle in the apical region, suggesting the diagnosis of coronary fistula (Figure 1A and B). Coronary angiography revealed aneurysmal ADA and vascular remodeling due to hyperflow, confirming the diagnosis of coronary-cavitary fistula (Figure 1C). The patient was submitted to percutaneous closure of the coronary fistula with Coil Vortex-18 device and presented good clinical evolution and improvement of renal function. It is important to consider the risks associated with EBM. Echocardiography is a valuable method for the evaluation of patients with suspected complications after the procedure. This case describes a rare complication after EBM and the diagnosis of which was possible by echocardiographic evaluation.
