Some congenital heart diseases include abnormalities in this area and can cause obstruction of the right ventricular outflow tract (RVOT). Infundibular pulmonary stenosis (IPS) is one of these cardiopathies and is often associated with other abnormalities, especially interventricular septal defect but, as an isolated presentation, it is considered a rare finding. Heart diseases may result in serious complications such as heart failure and infective endocarditis (IE). The latter has vegetation as a typical lesion. Vegetation is a mass of platelets and fibrin, in which microorganisms and inflammatory cells are captured. It can be precipitated by a valvulopathy or endocardial lesion. This report describes the case of a young patient admitted to a tertiary hospital with rare congenital pathology, whose diagnosis was made as a result of infective endocarditis.","PeriodicalId":211175,"journal":{"name":"ARQUIVOS BRASILEIROS DE CARDIOLOGIA - IMAGEM CARDIOVASCULAR","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133241386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnosis is not always simple due to phenotypic variation and concomitance with other pathologies. It is initially based on electrocardiographic and echocardiographic criteria and on the absence of other diseases occurring with ventricular hypertrophy. Having myofibrillar derangement and fibrosis as a cellular base resulting in hemodynamic abnormalities, hypertrophic cardiomyopathy may reveal myocardial ischemia (not related to atherosclerosis) and sudden death. Therefore, evaluation of functional repercussion with myocardial perfusion scintigraphy using the Single Photon Emission Computed Tomography (SPECT) has gained space, since 25% of patients with hypertrophic cardiomyopathy have fixed or ischemic perfusion defects. In this context, some perfusion disorders are not necessarily associated with the type of hypertrophic cardiomyopathy, but are able to predict morbidity and mortality in these individuals. Another recent scintigraphy technique is the positron emission tomography (PET), which stands out in the evaluation of microcirculation, coronary flow reserve and myocardial metabolism. In patients with hypertrophic cardiomyopathy, studies have shown unfavorable results when myocardial blood flow and coronary flow reserve are lower. Metabolic myocardial evaluation using PET seems to be useful in the pathophysiological understanding of this disease and in the prognostic evaluation of alcohol ablation, a procedure performed in severe obstructive forms. This review addresses the role of nuclear cardiology using SPECT and myocardial PET in the diagnostic, prognostic and therapeutic evaluation of hypertrophic cardiomyopathy.","PeriodicalId":211175,"journal":{"name":"ARQUIVOS BRASILEIROS DE CARDIOLOGIA - IMAGEM CARDIOVASCULAR","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123730032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this new and complex context, Cardiology has been a broad and fertile ground for AI approaches, as many heterogeneous and sufficiently prevailing diseases (ideal for large databases), such as heart failure and coronary artery disease, are yet to be sub-phenotyped in the constant pursuit of increasingly customized treatments. Besides, problems with acquisition time, high costs, efficiency and misdiagnosis are commonly observed and thus expected to be mitigated with the promising new applications of AI in cardiovascular propaedeutics.2","PeriodicalId":211175,"journal":{"name":"ARQUIVOS BRASILEIROS DE CARDIOLOGIA - IMAGEM CARDIOVASCULAR","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133831688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
