Abstract Cardiac masses represent solid formations of various origins, with accurate diagnosis being crucial, particularly for those of a malignant nature, which are typically associated with a worse prognosis. Given this diversity, a comprehensive approach often involves the integration of multiple imaging modalities. Conventional cardiovascular imaging techniques such as transthoracic echocardiography, magnetic resonance imaging (MRI), and cardiac tomography offer insights into anatomical features and hemodynamic implications associated with these masses. However, due to its limitations, greater precision in the etiological […]

Abstract Coronary microvascular dysfunction (CMD) is a condition that has been increasingly recognized as a cause of angina, with prognostic importance in multiple cardiovascular processes, especially in women. It results from abnormalities in the structure and/or function of the coronary microcirculation. Even in the absence of obstructive coronary artery disease (CAD), CMD is associated with worse prognosis, greater morbidity, impaired quality of life, and recurrent hospitalizations due to angina and heart failure, posing a challenge for diagnosis and treatment. In […]

Abstract Although assessing myocardial viability is a common cardiology practice, many physicians question the results of diagnostic methods. Nuclear medicine plays an important role in viability studies, but the reports require interpretation in a clinical and pathophysiological context. this article was aimed at reviewing the origin and evolution of myocardial viability. Here we present diagnostic methods by emphasizing nuclear medicine and provide a functional explanation of each test type using example images. We also propose how to act in these […]

Abstract Background: The use of myocardial perfusion scintigraphy in asymptomatic patients remains restricted to very specific clinical situations, many of which are addressed in the appropriate use criteria (AUC) for myocardial perfusion scintigraphy. Objective: To critically analyze the application of these criteria in indicating the tests performed in asymptomatic patients of the Dante Pazzanese Institute of Cardiology, a population that is notably at high cardiovascular risk. Methods: The study selected asymptomatic patients undergoing myocardial perfusion scintigraphy to investigate ischemia. Indications […]
