FIG. 1 Two-dimensional echocardiogram in parasternal long-axis view, showing a large mass (T) at the base of the heart with global pericardial effusion (PE). LV = left ventricle. FIG. 2 Single axial image from spiral computed tomography of the chest shows a large, heterogeneous enhancing mass (M) located anterior and to the right of the cardiac structures. It extends towards the right hilum (H)...

During the implantation process, the pacemaker leads advanced easily into the atrium and ventricle from the left subclavian vein. On fl uoroscopy, the locations of the leads in the atrium and ventricle appeared atypical (Fig. 1). An intraoperative transthoracic echocardiography was then performed, showing the atrial lead into the left atrium (Fig. 2). The pacemaker leads were then repositioned ...

A 47-year-old man presented at our emergency department with sudden-onset dyspnea, chest pain, tachycardia, and bilateral leg swelling. He had hypotension and tachycardia. His oxygen saturation was 82% and plasma D-dimer level was 455 μg/L. An electrocardiogram showed sinus tachycardia and an S1Q 3T3 pattern. Transesophageal echocardiography (TEE) revealed a large thrombus (cross-sectional area...

An infrequent but devastating late complication of Fontan circulation is protein-losing enteropathy (PLE), which results from unbalanced lymphatic homeostasis. Surgical decompression of the thoracic duct by redirecting its drainage to the pulmonary venous atrium has been introduced recently as a possible treatment. This report describes a single-institution experience with this innovative proce...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013200424 DESCRIPTION Single ventricle (SV) defects, including common inflow of both the atria emptying into one ventricle, occur at an incidence of 0.05–0.1/10 000 live-births. Common atrium is a rare variety of interatrial communication which forms a type of endocardial cu...

The M-mode and two dimensional echocardiographic features are described of a patient with rupture of a sinus of Valsalva aneurysm into the right atrium. A clear echo-free zone arising from the tip of the aneurysm is visualised in the right atrium in diastole by peripheral injection of echocardiographic contrast material. At surgery a fistula was seen between the non-coronary cusp and the right ...

A persistent left superior vena cava (PLSVC) is formed by the remains of the oblique vein of the left atrium, which is not completely degenerated during embryonic development. The incidence is approximately 0.3% in the general population. Approximately 80-92% of PLSVCs drain into the right atrium through the coronary sinus. This report describes a rare case of PLSVC in which the coronary sinus ...

With the advent of modern cardiac surgery the clinical diagnosis of intramural thrombi, ball valve thrombi and myxomatous and other tumors in the left atrium has assumed great importance. It is shown here that a diagnosis of thrombosis within the left atrium is possible by angiocardiography. The angiocardiographic features of mural and ball valve thrombi of the left atrium and of left auricular...

During the development of mammalian heart, left and right atria play an important role in cardiovascular circulation. The embryonic atrium is mainly formed by differentiation progenitor cells proliferation cardiomyocytes, while postnatal primarily shaped increase volume cardiomyocytes. Cell atrial basis for its functions such as “blood reservoir” “supplementary pump”. Deep understanding cellula...
