Isolated anomalous origin of the right coronary artery from the main pulmonary artery is a rare congenital anomaly, and few cases have been reported in the pediatric age group. Here in, we report an asymptomatic case of a 2-month-old male infant who has been diagnosed as anomalous origin of the right coronary artery from the main pulmonary artery during the evaluation for cardiac abnormalities. For a suspicion on echocardiography, cardiac catheterization and coronary angiography performed to verify the diagnosis of anomalous origin of the right coronary artery from the main pulmonary artery.

Cardiomyocyte autophagy and apoptosis are crucial events underlying the development of cardiac abnormalities and dysfunction after myocardial infarction (MI). A better understanding of the cell signaling pathways involved in cardiac remodeling may support the development of new therapeutic strategies for the treatment of heart failure (HF) after MI.
A cardiac MI injury model was constructed by ligating the left anterior descending (LAD) coronary artery.

The coronary vasculature is an essential vessel network providing the blood supply to the heart. Disruptions in coronary blood flow contribute to cardiac disease, a major cause of premature death worldwide. The generation of treatments for cardiovascular disease will be aided by a deeper understanding of the developmental processes that underpin coronary vessel formation.

To develop a document by Brazilian Cardiovascular Imaging Department (DIC) and the European Association of Cardiovascular Imaging (EACVI) to review and summarize the most recent evidences about the non-invasive assessment of patients with Chagas disease, with the intent to set up a framework for standardized cardiovascular imaging to assess cardiovascular morphologic and functional disturbances, as well as to guide the subsequent process of clinical decision-making.
Chagas disease remains one of the most prevalent infectious diseases in Latin America, and has become a health problem in non-endemic countries. Dilated cardiomyopathy is the most severe manifestation of Chagas disease, which causes substantial disability and early mortality in the socially most productive population leading to a significant economical burden.

Acute coronary syndrome with precordial ST segment elevation is usually related to left anterior descending artery occlusion, although isolated right ventricular infarction has been described as a cause of ST elevation in V1-V3 leads. We present a case of a patient with previous inferior wall infarction and new acute ST elevation myocardial infarction (STEMI) due to proximal right coronary thrombotic occlusion resulting in right ventricular infarction with precordial ST elevation and sinus node dysfunction. The patient was treated with successful rescue angioplasty achieving resolution of acute symptoms and electrocardiographic abnormalities.

The pathogenic events responsible for the reduction of endothelial progenitor cell (EPC) number and function seen in patients with chronic renal failure (CRF) are poorly understood. Here we investigate the hypothesis that increased concentrations of urea associated with CRF increase ROS production directly in EPCs, causing abnormalities associated with coronary artery disease risk.
Human EPCs were isolated from peripheral blood mononuclear cells of healthy donors and cultured in the presence or absence of 20 mmol/L urea.

Right ventricular hypoplasia (RVH) is often caused by tricuspid valve atresia and pulmonary valve atresia. this condition leads to low right ventricular blood volume and right ventricular maldevelopment. But, in adults, the main cause of RVH may also be associated with alloplasia of the right coronary artery, which results in an insufficient blood supply to the right ventricular myocardium.

Metabolic syndrome (MetS) is defined as a cluster of systemic abnormalities: hyperglycemia, dyslipidemia, abdominal obesity, and hypertension. Acute kidney injury (AKI) is one of the devastating complications after cardiac surgery. Age, DM, preexisting renal dysfunction, hypertension, impaired left ventricular function, and severe arteriosclerosis of the aorta are the major risk factors for the development of AKI.

Acute ST elevation in the anterior precordial leads typically suggests an anteroseptal infarction due to left anterior descending coronary artery obstruction, but the differential can be broad. Conus branch artery occlusion is a potentially overlooked cause of anteroseptal ST elevation myocardial infraction. Cardiac magnetic resonance (CMR) imaging is an emerging technology which can differentiate the etiology of anterior ST elevation in patients with no apparent coronary abnormalities on coronary angiography and normal echocardiography.

Left ventricular noncompaction (LVNC) is a myocardial disorder probably due to the arrest of normal embryogenesis of the left ventricle. It could be isolated or associated with other extracardiac and cardiac abnormalities, including coronary artery anomalies. Despite the continuous improvement of imaging resolution quality, this cardiomyopathy still remains frequently misdiagnosed, especially if associated with other heart diseases.

Heart failure (HF) with preserved ejection fraction (HFPEF) is still a challenge in clinical practice. The prognosis of patients with HFPEF is similar to or only slightly better than that of patients with HF with reduced ejection fraction (HFREF). Impaired relaxation is the mildest form of diastolic dysfunction, which should not be accompanied by symptoms of HFPEF.

Congenital left ventricular diverticulum is a rare cardiac malformation, which could result in rupture, thrombosis, congestive heart failure, infective endocarditis, ventricular arrhythmia and aortic insufficiency. Most authors propose that patients who are symptomatic and have a higher risk for major complications should undergo surgical treatment. We present a case of isolated congenital left ventricular diverticulum with mitral valve infective endocarditis and anomalous single coronary artery observed intra-operatively.

Hearts in which the arterial trunks arise from the morphologically appropriate ventricles, but in a parallel manner, rather than the usual spiralling arrangement, have long fascinated anatomists. These rare entities, for quite some time, were considered embryological impossibilities, but ongoing experience has shown that they can be found in various segmental combinations. Problems still exist about how best to describe them, as the different variants are often described with esoteric terms, such as anatomically corrected malposition or isolated ventricular inversion.

Undisturbed nasal breathing is essential for normal breathing physiology as a whole. Nasal septal deformities (NSD) are well known as a factor which can remarkably and substantially affect the quality of nasal and pulmonary breathing. However, it is well known that type 5 and type 6 nasal septal deformities may cause only a moderate, unilateral nasal obstruction or none at all.
