The maximum section column of townhouses in Takayama can be classified into type A [earthen floor type] and B [living space type]. dimensions columns tended to increase as the plane scale increased frontage widened. atrium area expand early Meiji period. We observed that form a standing one straight line at rectangle became crossing-axis structure ridge direction span irregularly shaped atrium,...

left atrial (la) distension has been demonstrated to be linked with aortic stiffness in different patient populations. three-dimensional (3d) speckle-tracking echocardiography (ste) seems to be a promising tool for volumetric and functional evaluation of the la. the aim of the present study was to determine whether correlations exist between 3dste-derived la volume-based and strain parameter...

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...

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...

In this thesis, we present novel medical image analysis methods to improve planning and outcome evaluation of cardiac ablation procedures. Cardiac ablation is a common medical procedure that consists of burning cardiac tissue causing atrial fibrillation, or irregular contractions of the heart’s atria. We first propose a method for the automatic delineation of the left atrium in magnetic resonan...
