INTRODUCTION Surgery for primary non-resectable malignant tumors of the left atrium is controversial. Today heart autotransplantation as a method of surgical treatment for patients suffering primary massive malignant tumors of the left atrium is still not sufficiently studied. MATERIAL AND METHODS We provide information on our single-center 5-year experience in performing surgical interventio...

Shaped like a wizard’s hat but long considered functionally insignificant, the conical, trabeculated left atrial appendage (LAA) arises from the embryonic left atrium during the third week of gestation and extends superiorly from the anterolateral surface of the left atrium (1). This accessory chamber extends over an area of 3 to 6 cm, is more compliant than the atrium, and is actively contract...

General considerations: The heart is the first organ to form in the embryo. In mammalians and birds it consists of 4 chambers (2 atria and 2 ventricles). The heart functions to maintain adequate blood flow (cardiac output) with the purpose of delivering oxygen and nutrients to the tissues and the removal of waste metabolic products. The systemic circulation returns non-oxygenated blood to the r...

A 57-year-old man presented to our emergency department with altered mental status. He had a past medical history significant for cirrhosis and previous placement of a transjugular intrahepatic portosystemic shunt (TIPS). On cardiac auscultation, a new heart murmur and an unexpected degree of cardiac ectopy were noted. On the 12-lead electrocardiogram, the patient was noted to have multiple pre...

Ruptured noncoronary sinus of valsalva aneurysm with fistulous connections to multiple cardiac chambers has not been reported previously. We report a 66-year-old man who presented with worsening cough and exertional dyspnea. Transesophageal echocardiogram confirmed a large aneurysm involving the noncoronary cusp of the aortic sinus with aneurysmal extension to the left atrium. There were also t...

We report a case of angiosarcoma of the right atrium, manifested as a cardiac tamponade. The patient was a 57-year-old man. Transesophageal echocardiographic examination revealed a pericardial effusion and an abnormal structure arising in the right atrium. Emergency operation was performed and the tumor in the right atrium was resected under cardiopulmonary bypass. The resected tumor measured 5...

The calculated systolic, diastolic and mean pulmonary artery pressure, the ratio of sizes right left ventricles heart, eccentricity index ventricle, systolic excursion fibrous ring tricuspid valve, movement myocardium at level valve area atrium are main echocardiographic indicators for assessing idiopathic similar forms hypertension according to current Russian, Eurasian European guidelines in ...

Raghib syndrome is an extremely rare congenital heart defect characterized by persistent left superior vena cava (LSVC) draining into the left atrium and absence of the coronary sinus. Although few cases have been reported in the literature, there are a number of techniques to redirect the LSVC flow to the right atrium. These procedures include surgery to establish intracardiac flow using atria...

ABSTRACTThe valves of right horn of systemic venous sinus are prominent structures within the right atrium during early embryonic period. Involution of these structures may not be complete, resulting in a spectrum of anatomical presentations such as cyanosis. A full-term male neonate referred to our hospital for precise evaluation of severe cyanosis on the first day of life. Echocardiographic e...

The embryonic vertebrate heart is composed of two major chambers, a ventricle and an atrium, each of which has a characteristic size, shape and functional capacity that contributes to efficient circulation. Chamber-specific gene expression programs are likely to regulate key aspects of chamber formation. Here, we demonstrate that epigenetic factors also have a significant influence on chamber m...
