Introduction Spontaneous coronary artery dissection (SCAD) remains a diagnostic and therapeutic challenge in the evaluation of chest pain. Misinterpretation of symptom characteristics and failure to consider the patient’s epidemiological profile may lead to inappropriate diagnostic workups and treatment strategies. The case described herein represents only the second report with similar characteristics published in major medical databases. This case underscores the importance of considering uncommon causes of chest pain and acute coronary syndrome (ACS), while also providing a brief review of […]

Abstract Background: Myocardial perfusion scintigraphy is an important non-invasive method for diagnosing coronary artery disease, but it is not free from artifacts. Performing the combined supine-prone protocol can bring benefits to images with artifacts from the standard protocol in the supine position. The lack of unanimity in the implementation of the combined protocol may be related to the lack of objective data for the prior selection of patients. Objective: To evaluate which anthropometric profiles may be associated with a greater […]

Abstract Takayasu’s Arteritis (TA) is a disease of multiple presentation, which can involve many different systems and mainly affects women in the first decades of life. The present case reports on a 19-year-old patient with TA, with a diagnosis of ascending aortic aneurysm and severe coronary artery disease in the right coronary artery (RCA) and left coronary trunk (LCT), who underwent an implant of a supracoronary Dacron graft in the ascending aorta and myocardial revascularization with a double internal thoracic […]

Abstract Pediatric heart transplantation is the definitive therapeutic option for patients with heart failure refractory to optimized clinical treatment, due either to cardiomyopathies or congenital heart disease. Morbidity and mortality remain concerning factors during evolution, and primary dysfunction, rejection, and graft vascular disease (GVD) are the main causes of death in the first 5 years after transplantation. As a surveillance method, transthoracic echocardiography has significant benefits in assisting diagnosis when there is clinical suspicion of rejection or GVD. The objective […]

Abstract Background Coronary computed tomography angiography is a noninvasive anatomic test for the diagnosis of coronary artery disease. The coronary fractional flow reserve is the gold standard method to determine if coronary stenosis is hemodynamically significant but requires an invasive procedure. Fractional flow reserve measurement by tomography is a new method to determine the hemodynamic significance of coronary luminal reduction. Objective To compare the accuracy of the invasive fractional flow reserve with the fractional flow reserve measurement by tomography. Method […]
