RESUMO

Abstract Background There has been an increase in the number of cases of Takotsubo syndrome (TTS) and of scientific publications on the theme over the last years. However, little is known about the status of this disease in Brazilian hospitals. Objective To assess mortality and major adverse cardiovascular events (MACE) during hospitalization and follow-up of TTS patients seen in a tertiary hospital in Brazil. Methods This was a retrospective, observational study on 48 patients. Clinical data, signs and symptoms, complementary tests, MACE and all-cause mortality were assessed on admission and during follow-up. Kaplan-Meier curves were used for analysis of all-cause mortality and risk for MACE at median follow-up. The 95% confidence interval was also calculated for a significance level of 5%. Results Mean age of patients was 71 years (SD±13 years), and most patients were women (n=41; 85.4%). During hospitalization, four patients (8.3%) died and five (10.4%) developed MACE. At median follow-up of 354.5 days (IQR of 81.5-896.5 days), the risk of all-cause mortality and MACE was 11.1% (95% CI= 1.8-20.3%) and 12.7% (95% CI= 3.3-22.3%), respectively. Conclusion TTS was associated with high morbidity and mortality rates in a tertiary hospital in Brazil, which were comparable to those observed in acute coronary syndrome. Therefore, the severity of TTS should not be underestimated, and new therapeutic strategies are required. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0

RESUMO

OBJECTIVES: Concomitant valvular heart valve disease is a frequent finding, with higher morbidity and mortality among patients undergoing redo surgical procedures. Our goal was to report our initial experience with combined transcatheter Inovare bioprosthesis implants for severe valve dysfunction. METHODS: Among 300 transcatheter procedures, a total of 6 patients had concurrent simultaneous transcatheter bioprosthesis implants for severe mitral bioprosthesis failure (valve-in-valve), with a second valve procedure that included native aortic (n = 2) or degenerated bioprostheses in the aortic position (n = 4). During the procedures, all patients were treated with a balloon-expandable Inovare transcatheter valve, using the transapical approach. RESULTS: Patients were highly symptomatic [New York Heart Association (NYHA) functional class IV: 100%], with a mean age of 62 ± 5 years, yielding a mean European System for Cardiac Operative Risk II (EuroSCORE II) of 24.0 ± 10.1%. There was a mean of 1.6 ± 0.4 prior valve operations/patient, with a median time from prior mitral bioprosthesis surgery of 13.0 (9.2-20.0) years. Device success was 100% according to the Mitral Valve Academic Research Consortium and the Valve Academic Research Consortium-2 criteria. During the hospital stay, only 1 patient required dialysis, and the median intensive care unit and hospital lengths of stay were 5.0 (3.2-6.7) days and 16.0 (12.2-21.2) days, respectively. No deaths occurred at 30 days; at a median follow-up of 287 (194-437) days, 1 patient died of a non-cardiac cause and the rest of patients were in NYHA functional class I or II, with normofunctioning bioprostheses. CONCLUSIONS: Transcatheter double valve interventions using the Inovare bioprosthesis in this initial series were shown to be a reasonable alternative to redo surgical operations. The short- and mid-term clinical and echocardiographic outcomes demonstrate promising results, although future studies with a larger number of patients and longer follow-up are warranted.

RESUMO

In accordance with the "Standards for the Elaboration of Guidelines, Positions and Normations" sanctioned by the Brazilian Society of Cardiology, this document was written to update the "Echocardiography Indication Guidelines" of 2009. The new document is not intended to be a comprehensive review of echocardiography, but rather an indispensable basic guide to support the rational clinical decision-making of the physician requesting the exam for adult patients. Although it considers the recent technological advances of echocardiography, its purpose is not to describe in detail echocardiography methods, but to summarize in a clear and concise way the main situations in which echocardiography brings benefit to the diagnosis and/or therapeutic orientation of the individual. This manuscript chose to highlight the class of recommendation, as described below: Class I: conditions for which there is conclusive evidence or, in the absence thereof, general agreement that the examination procedure is useful and safe. Class II: conditions for which there is conflicting evidence and/or divergence of opinion on the utility and/or safety of the examination. Class-IIa: evidence or opinions favorable to the examination. Most experts approve. Class IIb: utility and/or safety less well established, with divergent opinions. Class III: conditions for which there is evidence or consensus that the examination is not useful and, in some cases, may even be harmful. In addition, the level of evidence was also described, as follows: A: several concordant randomized clinical trials or robust meta-analyses; B: less robust meta-analysis data or single randomized clinical study or observational studies; C: expert opinion.(AU)

RESUMO

La ecocardiografía permite detectar y cuantificar la disfunción diastólica utilizando numerosos parámetros que parecen volver muy compleja esa tarea, particularmente en disfunciones más severas. En este artículo son revisados y actualizados los parámetros utilizados y los recursos tecnológicos disponibles. Es propuesto un algoritmo para orientar la incorporación progresiva de las variables necesarias de acuerdo con los hallazgos. La evaluación realizada, de manera metódica siguiendo un algoritmo adecuado, permite llegar al diagnóstico con elevada sensibilidad y especificidad en la casi totalidad de los casos, haciendo de la ecocardiografía el mejor método no invasivo para el diagnóstico y evaluación de esta frecuente disfunción

RESUMO

BACKGROUND: Considering the potential deleterious effects of right ventricular (RV) pacing, the hypothesis of this study is that isolated left ventricular (LV) pacing through the coronary sinus is safe and may provide better clinical and echocardiographic benefits to patients with bradyarrhythmias and normal ventricular function requiring heart rate correction alone. OBJECTIVE: To assess the safety, efficacy, and effects of LV pacing using an active-fixation coronary sinus lead in comparison with RV pacing, in patients eligible for conventional pacemaker (PM) implantation. METHODS: Randomized, controlled, and single-blinded clinical trial in adult patients submitted to PM implantation due to bradyarrhythmias and systolic ventricular function ≥ 0.40. Randomization (RV vs. LV) occurred before PM implantation. The main results of the study were procedural success, safety, and efficacy. Secondary results were clinical and echocardiographic changes. Chi-squared test, Fisher's exact test and Student's t-test were used, considering a significance level of 5%. RESULTS: From June 2012 to January 2014, 91 patients were included, 36 in the RV Group and 55 in the LV Group. Baseline characteristics of patients in both groups were similar. PM implantation was performed successfully and without any complications in all patients in the RV group. Of the 55 patients initially allocated into the LV group, active-fixation coronary sinus lead implantation was not possible in 20 (36.4%) patients. The most frequent complication was phrenic nerve stimulation, detected in 9 (25.7%) patients in the LV group. During the follow-up period, there were no hospitalizations due to heart failure. Reductions of more than 10% in left ventricular ejection fraction were observed in 23.5% of patients in the RV group and 20.6% of those in the LV group (p = 0.767). Tissue Doppler analysis showed that 91.2% of subjects in the RV group and 68.8% of those in the LV group had interventricular dyssynchrony (p = 0.022). CONCLUSION: The procedural success rate of LV implant was low, and the safety of the procedure was influenced mainly by the high rate of phrenic nerve stimulation in the postoperative period.

Resumo Fundamento: Considerando-se os potenciais efeitos deletérios da estimulação do ventrículo direito (VD), a hipótese desse estudo é que a estimulação unifocal ventricular esquerda pelo seio coronário é segura e pode proporcionar melhores benefícios clínicos e ecocardiográficos aos pacientes com bradiarritmias que apresentam função ventricular normal, necessitando apenas da correção da frequência cardíaca. Objetivos: Avaliar a segurança, a eficácia e os efeitos da estimulação do ventrículo esquerdo (VE), utilizando um cabo-eletrodo com fixação ativa, em comparação à estimulação do VD. Métodos: Estudo clínico, randomizado, simples-cego em pacientes adultos com indicação de marca-passo (MP) devido a bradiarritmias e função ventricular sistólica ≥ 0,40. A randomização aleatória (VD vs VE) ocorreu antes do procedimento. Os desfechos primários do estudo foram: o sucesso, a segurança e a eficácia do procedimento proposto. Os desfechos secundários foram: a evolução clínica e alterações ecocardiográficas. Empregou-se os testes Qui-quadrado, Exato de Fisher e t de Student, com nível de significância de 5%. Resultados: De junho de 2012 a janeiro de 2014 foram incluídos 91 pacientes, sendo 36 no grupo VD e 55 no grupo VE. As características basais dos pacientes dos dois grupos foram similares. O implante de MP foi realizado com sucesso e sem nenhuma intercorrência em todos os pacientes do grupo VD. Dos 55 pacientes inicialmente alocados para o grupo VE, o implante do cabo-eletrodo em veias coronárias não foi possível em 20 (36,4%) pacientes. Dentre os 35 pacientes que permaneceram com o cabo-eletrodo no VE, a estimulação frênica foi a complicação mais frequente e foi detectada em 9 (25,7%) pacientes. Na fase de seguimento clínico, não houve hospitalizações por insuficiência cardíaca. Reduções superiores a 10% na fração de ejeção do VE foram observadas em 23,5% dos pacientes do grupo VD e em 20,6% dos pacientes do grupo VE (p = 0,767). A análise feita pelo Doppler tecidual mostrou que 91,2% dos indivíduos do grupo VD e 68,8% dos do grupo VE apresentaram dissincronia interventricular (p = 0,022). Conclusões: A taxa de sucesso do implante no VE foi baixa e a segurança do procedimento foi influenciada, principalmente, pela alta taxa de estimulação frênica no pós-operatório.
