Anatomy Of The Coronary Arteries

Left coronary artery It starts with an ostium placed at the half of the left coronary sinus, heading for the left coronary sulcus, situated between the pulmonary artery trunk and left ears. After this short route, it usually divides into two branches: the left anterior descending artery and the circumflex artery. Sometimes it can be […]

Dextrocardia

The heart is a muscular organ, cone-shaped or triangular (was compared even with a pear), pointing down and to the left. It is located in the chest; it is supported to the diaphragm, in the middle mediastinum, a third of which is located to the right of the midline and two-thirds to the left midline. […]

CT coronary angiography

Cardiovascular diseases are the first cause of morbidity and mortality in developed countries. An early diagnosis with the lowest costs it was necessary, which led to the development of both imaging examination techniques as well as medical devices, focusing lately on computer tomography examination and on the cardiac magnetic resonance. Examination of multislice CT angiography […]

Echocardiography in hypertensive cardiomyopathy

Hypertensive cardiomyopathy defines all structural, morphological and functional cardiac effects caused by direct/indirect chronic high blood pressure. Are included: left ventricular hypertrophy, coronary artery disease, cardiac arrhythmias (atrial fibrillation, ventricular extrasystoles, ventricular tachycardia) and heart failure. Transthoracic echocardiography is a noninvasive method that can be performed with new portable systems at bedside and highlights different […]

Myocardial Bridge

Myocardial bridge is an anomaly characterized by intramyocardial paths of an epicardial coronary artery segment. It was found during autopsies in 1737 and described angiographically in 1960. Typical angiographic aspect of myocardial bridge is systolic narrowing of the artery, alternatively with returning to normal during the diastolic phase of the cardiac cycle. Describing image: “milking […]

Hypertrophic Cardiomyopathy – Interventional Treatment

Hypertrophic cardiomyopathy (HCM) is a common familial autosomal dominant heart condition, with a heterogeneous phenotypic expression, characterized by left ventricular hypertrophy in the absence of associated conditions that could explain it (high blood pressure, aortic stenosis). Hypertrophic cardiomyopathy is probably the most common genetically transmitted cardiovascular disease, with a prevalence in the general population of about 0.2%. […]

Ebstein’s Disease

Ebstein’s disease is an abnormality of the tricuspid valve in which the septal foil and the posterior foil are shifted to the right ventricular apex and the anterior foil is usually malformed, excessively big and abnormally attached to the right ventricular free wall. Thus, a portion of the right ventricular is “atrialization“ in the portion […]

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia (ARVD) is an cardiomyopathy with transmission of autosomal dominant type with incomplete penetrance and variable expression associated with malignant ventricular arrhythmias and sudden death in young, apparently healthy people, characterized by structural and functional abnormalities of the right ventricular zone given by replacement of the myocardium with fatty and fibrous tissue. […]

Restrictive Cardiomyopathy

Restrictive cardiomyopathy is a rare disease in which the heart muscle becomes stiff and cannot relax normally during activity, so the ventricles (lower chambers) do not receive enough blood that is then pumped to other organs. Because the ventricles cannot relax normally, the blood is sent back (upstream) in the bloodstream. Restrictive cardiomyopathy is rare […]

Dilated Cardiomyopathy

Dilated cardiomyopathy is a serious condition in which the heart muscle is weakened and no longer has the strength to pump blood throughout the body. Weakened heart cannot pump much blood, so that more blood remains at this level after each heartbeat. As the larger quantities of blood remains in the lower chambers of the […]
