Abstract Infective endocarditis remains a serious condition with high morbidity and mortality rates despite advances in diagnostic and therapy. While the Global North has seen a shift toward older patients with prosthetic valve infections, Brazil’s understanding of the disease is hindered by reliance on fragmented, hospital-based data, primarily from the Southeast region. This narrative review synthesizes recent evidence to outline the national panorama. Population studies indicate an increase in incidence and mortality, primarily affecting men and the elderly, but with […]

Abstract Left ventricular (LV) pseudoaneurysm is a rare complication of acute myocardial infarction (AMI). We report the case of a 67-year-old male patient seen in 2024. Following an AMI in 2019, the patient was diagnosed with a LV pseudoaneurysm after complaining of dyspnea and undergoing imaging tests including echocardiogram and magnetic resonance imaging. The patient underwent aneurysmectomy and revascularization surgery, progressing satisfactorily during the postoperative period.

Introduction Infectious endocarditis (IE) is defined as the infection of the endocardium or prosthetic material in the heart, whose pathogenesis is bacterial adherence to the vulnerable endocardium or implanted prosthetic material during a bacteremia. Its clinical presentation is highly variable, depending on the micro-organism that causes it, underlying heart conditions and preexisting comorbidities. The annual estimated incidence of IE is up to 10/100,000 in western countries, and mortality of up to 30% in 30 days. […]

Introduction Cardiac angiosarcoma is a rare malignant endothelial tumor that is aggressive and has an adverse prognosis., It features a high mortality rate because of the tendency for local recurrence and high incidence of systemic metastases. Therefore, its early diagnosis is very important, as is the determination of its local and distant extension, to ensure its proper therapeutic management. The objective of this case report was to show the value of positron emission tomography associated with computed tomography with 18-fluorodeoxyglucose […]

Introduction The left internal thoracic artery (LITA) fistula to the pulmonary artery (PA) and/or its branches is a rare condition that was first described in 1947 by Burchell and Clagett and can be acquired or congenital. Its etiologies include, trauma, infection, neoplasms, and mainly myocardial revascularization surgery (MRS)., The surgical manipulation of the intrathoracic vessels during MRS may predispose a patient to postoperative LITA fistulization to the PA, causing coronary flow leakage and myocardial ischemia. LITA should be considered an […]

Abstract Background: Heart failure with reduced ejection fraction is responsible for half of heart failure cases worldwide and implicates in substantial morbidity and mortality. However, even with clinical history and physical examination associated with conventional complementary exams, many patients remain without etiological diagnosis. Cardiac magnetic resonance has offered the possibility to clarify a variable proportion of these cases. Objective: To verify how much cardiac magnetic resonance contributes to etiologic diagnosis of heart failure with left ventricular ejection fraction

Introduction Coronary artery anomalies (CAAs) are characterized by a changed vessel origin, path, or structure. It is a rare condition, present in approximately 1% of the general population. These anomalies include the anomalous aortic origin of a coronary artery (AAOCA), which can travel retroaortic, subpulmonic, prepulmonic, and inter-arterial courses. In general, these abnormalities remain asymptomatic until adulthood, being incidental findings on complementary tests or necropsy. However, they can also cause angina, syncope, ischemia, arrhythmias, or sudden death., Sudden death can […]

Introduction Left ventricular (LV) pseudoaneurysm after acute myocardial infarction may show nonspecific symptoms and be asymptomatic in up to 10% of cases. It demands investigation and a suspected diagnosis, with imaging methods playing a fundamental role in its diagnosis. This case report describes a pseudoaneurysm detected on a routine examination. […]

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 […]
