The use of decellularized allografts was safe and with good medium-term results up to 4 years. There was a tendency to lower late gradients in the SDS decellularized allografts after 12 months.

Background: In ST-segment elevation myocardial infarction, the need for early recanalization of the culprit artery, associated to the difficult access of the general population to medical services that provide such treatment, contribute to increased mortality in such patients. This is the rationale for implementing the LATIN project, acronym for Latin America Telemedicine Infarct Network, in areas characterized by high demographic density and difficult access to healthcare services. The objective of the present study was to analyze the first year results of this project. Methods: The sample included six centers with telemedicine systems participating in the LATIN registry. In cases of acute myocardial infarction, the electrocardiogram and clinical summary were sent to the mobile phones of the interventional cardiologists at the reference hospital. Clinical and angiographic characteristics, intervals between care delivered and hospital outcomes were analyzed. Results: From June 2014 to June 2015, a total of 125 patients were enrolled, mean age of 58.3±11.1 years, 66.4% males, 30.4% suffering from diabetes mellitus and 28.8% smokers. A total of 85 primary percutaneous coronary interventions were performed with a mean door-to-balloon time of 46.4±25.0 minutes. The pharmaco-invasive strategy was adopted in 20.0% of patients. In-hospital mortality was 5.6%. Conclusions: The telemedicine system was a valuable partner in early diagnosis and rapid initiation of the gold standard treatment for acute myocardial infarction in the region analyzed, with possible impact in survival, cost reduction and morbimortality. RESUMO -Introdução:No infarto agudo do miocárdio com supradesnivelamento do segmento ST, a necessidade de recanalização precoce da artéria culpada, associada às dificuldades de acesso da população em geral aos serviços médicos que realizam esta modalidade de tratamento, contribui para o aumento da mortalidade nesse perfil de paciente. Diante do exposto, encontra-se o racional de implementação do projeto denominado LATIN, acrônimo para Latin America Telemedicine Infarct Network, em áreas caracterizadas por concentração demográfica densa e dificuldades de acesso à saúde. O objetivo do presente estudo foi analisar os resultados do primeiro ano deste projeto. Métodos: A amostra compreendeu seis centros dotados de telemedicina participantes do registro LATIN. Nos casos de infarto agudo do miocárdio, eletrocardiograma e resumo clínico eram encaminhados por mensagem para os celulares dos cardiologistas intervencionistas do hospital de referência. Foram analisadas as características clínicas, angiográficas, os intervalos de atendimento e os desfechos hospitalares. Resultados: De junho de 2014 a junho de 2015, foram incluídos 125 pacientes, com média de idade de 58,3±11,1 anos, 66,4% do sexo masculino, 30,4% portadores de diabetes melito e 28,8% tabagistas. Foram realizadas 85 intervenções coronárias percutâneas primárias, com tempo porta-balão médio de 46,4±25,0 minutos. A estratégia fármaco-invasiva foi realizada em 20,0...
