ABSTRACT Introduction: The coronary artery bypass grafting (CABG) data provided by the Brazilian Registry of Cardiovascular Surgeries in Adults (BYPASS) Registry is a Brazilian reality. Objective: To carry out a comparative exercise between the BYPASS Registry published data and data from patients operated on in a randomly chosen period (2013-2015) at Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP). Methods: This is a retrospective study reviewing 173 electronic medical records of CABG patients from the HCFMRP-USP. These data were compared with the BYPASS Registry published data. Chi-square test was used to verify the changes within the prevalence of adequate/inadequate biochemical tests before and after surgery. The sample was divided into groups consistent with cardiopulmonary bypass (CPB) time (CPB ≤ 120 minutes and CPB > 120 minutes). For the complications, prevalence by the chi-square test was adopted. Significant P-values are < 0.05. Results: The comparative operative data of the BYPASS Registry and the HCFMRP-USP patients were quite similar, except for the isolate use of only arterial grafts, which was more frequent on HCFMRP-USP patients (30.8% vs. 15.9%), and the use of radial artery, also more frequent on HCFMRP-USP patients (48.8% vs. 1.1%) Conclusion: The comparative study suggested that the BYPASS Registry should be a reference for CABG quality control.

Resumo Fundamento: Geralmente vista como uma característica da velhice, a fragilidade também pode ocorrer em pessoas não idosas, principalmente naquelas que sofrem de doenças crônicas. A fragilidade pode aumentar o risco operatório. Objetivos: Determinar a prevalência de fragilidade em pacientes submetidos à cirurgia de revascularização do miocárdio (CRM) e/ou troca ou reconstrução valvar e/ou cirurgia valvar, bem como a influência da fragilidade nos desfechos pós-operatórios. Métodos: Nosso estudo incluiu 100 adultos que foram submetidos a operações cardíacas eletivas consecutivas. A fragilidade foi avaliada por meio da escala de Fried. Os pacientes também realizaram um teste de caminhada de 6 minutos, e medimos as pressões inspiratória e expiratória máximas. Um valor de p < 0,05 foi considerado significativo. Resultados: De uma coorte de 100 pacientes, com base nos critérios de fragilidade de Fried, 17 pacientes (17%) foram considerados frágeis, 70 (70%) pré-frágeis e apenas 13 (13%) não frágeis. Entre os portadores de valvopatia, 11 (18,6%) foram considerados frágeis e 43 (73%) pré-frágeis. Cinquenta e três por cento dos pacientes considerados frágeis tinham menos de 60 anos (mediana=48 anos). As diferenças no fenótipo de fragilidade entre os pacientes com valvopatia e doença arterial coronariana não foram estatisticamente significativas (p=0,305). A comparação entre pacientes não frágeis, pré-frágeis e frágeis não mostrou diferença significativa na distribuição das comorbidades e do estado funcional cardíaco, independentemente da doença cardíaca. No entanto, a mortalidade hospitalar mostrou-se significativamente maior em pacientes frágeis (29,4%, p=0,026) que em pacientes pré-frágeis (8,6%) e não frágeis (0%). Conclusões: A fragilidade é prevalente mesmo entre pacientes não idosos submetidos a CRM ou cirurgia cardíaca valvar e está associada a maior mortalidade hospitalar pós-operatória.

Abstract Background: Usually viewed as a characteristic of old age, frailty may also occur in non-elderly people, primarily in those suffering from chronic disease. Frailty may increase operative risk. Objectives: To determine the prevalence of frailty patients undergoing coronary artery bypass (CABG) and/or heart valve replacement or reconstruction and/or heart valve surgery, as well as the influence of frailty on postoperative outcomes. Methods: Our study comprised 100 adults who underwent consecutive elective cardiac operations. Frailty was assessed using the Fried scale. Patients also performed a 6-minute walk test, and we measured maximal inspiratory and expiratory pressures. A p value <0.05 was considered significant. Results: Of a cohort of 100 patients, based on the Fried frailty criteria, 17 patients (17%) were considered frail, 70 (70%) pre-frail and only 13 (13%) were non-frail. Among patients with valvular heart disease, 11 (18.6%) were considered frail and 43 (73%) pre-frail. Fifty three percent of the patients considered frail were less than 60 years old (median=48 years old). The differences in frailty phenotype between patients with valvular heart disease and coronary artery disease were not statistically significant (p=0.305). A comparison between non-frail, pre-frail, and frail patients showed no significant difference in the distribution of comorbidities and cardiac functional status, regardless of their cardiac disease. However, hospital mortality was significantly higher in frail patients (29.4%, p=0.026) than in pre-frail patients (8.6%) and non-frail patients (0%). Conclusions: Frailty is prevalent even among non-elderly patients undergoing CABG or valvular heart surgery and is associated with higher postoperative hospital mortality.

Abstract Scientific progress shall ultimately boost the current acceptance level for conservative aortic valve surgery. The present text aimed to report the 23-year long-term follow-up of one patient operated with bovine pericardium cusp extension. Growing confidence in the efficacy of the operation will allow a more expeditious indication for surgical treatment, as is already the case in mitral valve repair. This change of attitude will certainly make it possible for patients to be sent for operation in mild aortic valve regurgitation. The present report reinforces the concept and highlights the impression that the aortic valvoplasty, independent of the progressive bovine pericardium degeneration, may positively change the natural history of the aortic valve insufficiency.

Abstract Validation of transendocardial injection as a method for delivering therapeutic agents to the diseased heart is increasing. Puncture heart biopsies should re-emerge as a possible alternative method to allow access to the myocardium and implantable biomaterial for cell therapy. Therefore, this work aims to present a percutaneous puncture device for biopsy and intramyocardial biomaterial injection, standardize the technique and attest to the safety of the method. The adaptation consists of creating myocardial microlesions that allow for better fixation of stem cells. The objective of this technical note covers only the development of the needle and the histological quality of the biopsies. It has not been used in humans yet.

Resumo Uma visão geral de estudos angiográficos na literatura mostrou que a prevalência da doença coronária significativa em pacientes com estenose aórtica (EA) varia de 20 a 60%. Os estudos iniciais de necropsia sugeriram que pacientes com EA tinham uma incidência abaixo do esperado de doença arterial coronariana (DAC), assim originando-se o conceito de um efeito protetor da EA nas artérias coronárias. O mito da proteção EA contra a DAC seria melhor explicado como uma interação endotélio-miocárdio (crosstalk) desencadeada pela sobrecarga do ventrículo esquerdo. Portanto, a via cGMP/NO, (guanosina monofosfato cíclico/Óxido nítrico) induzida pela pressão de sobrecarga da EA, explicaria a baixa incidência de DAC, o que é compatível com a surpreendente evolução natural em longo prazo dessa doença valvar cardíaca.

Abstract A literature overview of angiographic studies has shown that the prevalence of significant coronary disease in patients with aortic stenosis (AS) varies from 20 to 60%. Early necropsy studies suggested that patients with AS had a lower than expected incidence of coronary artery disease (CAD), originating the concept of a protective effect of AS on the coronary arteries. The myth of AS protection against CAD would be better explained as endothelium-myocardial interaction (crosstalk) protection triggered by left ventricular overload. Therefore, the cGMP/NO pathway induced by the AS overload pressure would explain the low incidence of CAD, which is compatible with the amazing natural long-term evolution of this cardiac valve disease.

PURPOSE: Cardiopulmonary bypass (CPB) procedures are thought to activate systemic inflammatory reaction syndrome (SIRS). Strategies to curb systemic inflammation have been previously described. However, none of them is adequate, since "curbing" the extent of the inflammatory response requires a multimodal approach. The aim of the present mini-review is to discuss the main key points about the main principles in cardiopulmonary bypass curbing inflammation. METHODS: No systematic literature search (MEDLINE) and extracted data from the accumulated experience of the authors. The preconceived idea of an association between severe inflammation and coagulation disorders is reviewed. Also, some fundamental concepts, CPB inflammatory biomarkers, the vasoplegic syndrome and the need forindividual CPB protocols for children, diabetes and old patients, are discussed. CONCLUSION: The ways in which surgical technique (atraumatic vein harvest, biocompatibility and shear resistance of the circuit, monitoring, minimizing organ ischemia, minimal cross-clamping trauma, and blood management) are thought to curb SIRS induced by CPB and affect positively the patient outcome.Improved patient outcomes are strongly associated with these modalities of care, more than single or combinatorial drug strategies (aprotinin, tranexamic acid, pentoxifylline) or CPB modalities (minicircuits, heparin-coated circuits, retrograde autologous prime).

Sabe-se que a anestesia e determinadas cirurgias predispõem a alterações na mecânica respiratória, volumes pulmonares e trocas gasosas. A cirurgia cardíaca, considerada de grande porte, pode desencadear alterações respiratórias no pós-operatório, sendo estas relacionadas a causas diversas, como funções pulmonar e cardíaca no pré-operatório, utilização de circulação extracorpórea (CEC) e grau de sedação. Nestes procedimentos torácicos extensos, a disfunção respiratória pode ser importante, persistindo no período pós-operatório. A Fisioterapia faz parte do atendimento multidisciplinar oferecido aos pacientes em Unidade de Terapia Intensiva, sendo sua atuação extensa, presente em várias etapas do tratamento intensivo, principalmente na recuperação pós-cirúrgica, com o objetivo de evitar complicações respiratórias e motoras. Sendo assim, realizou-se uma revisão bibliográfica com o objetivo de reunir informações atuais e relevantes sobre recursos disponíveis para a monitorização respiratória, bem como a sua importância para avaliação e atuação diante de alterações na função pulmonar, uma vez que tal complicação é causa freqüente de óbito em pacientes operados.

It is well known that anesthesia and certain surgeries predispose patients to changes in respiratory function, pulmonary volumes, and gas exchange. Cardiac surgery, which is considered a major surgery, may trigger respiratory complications in the postoperative period. These complications have various causes, such as heart and lung functions in the pre-operative, the use of cardiopulmonary bypass (CPB), and the level of sedation. In these extensive thoracic procedures, respiratory dysfunction may be significant, persisting in the postoperative period. Physiotherapy is offered to patients in the ICU as part of a multidisciplinary treatment plan. It is a time-consuming treatment, and is possible at various times during the patient's stay in the ICU. However, it is particularly valuable in postoperative recovery in order to avoid respiratory and motor complications. Thus, a literature review was performed, aiming to arrange current and relevant information on available resources for respiratory monitoring, as well as its importance in evaluating and treating lung function impairment, as this complication is a frequent cause of death in surgical patients.
