During gestation period the oxygenated maternal blood is transferred to embryo via placenta and umbilical cord into right atrium. It further through an interatrial shunt left atrium, Foramen Ovale, distributed embryonic body. The foramen closed after birth, but remains occasionally patent, permitting embolization a shunt. This transferring thrombi, fat, cement bony spikes, air, malignant tissue...
OBJECTIVES Our purpose was to determine whether atrial fibrillation (AF) patients have alterations in sarcoplasmic reticulum (SR) Ca2+ regulatory proteins in the atrial myocardium. BACKGROUND Clinically, AF is the most frequently encountered arrhythmia. Recent studies indicate that an inability to maintain intracellular Ca2+ homeostasis with a consequent increase in membrane-triggered activit...
Biatrial tachycardia (BiAT) is a rare arrhythmia, and identification of the re-entry circuit often complicated. By creating an activation map right atrium, left coronary sinus as single chamber, LUMIPOINT module Rhythmia mapping system (Boston Scientific, Marlborough, MA, USA) can be used in real time to make accurate diagnosis. Ablation Bachmann bundle feasible way terminate BiAT, but might ca...
A 12-year-old spayed female miniature Poodle presented for coughing, respiratory distress, and anorexia. After thoracentesis for pleural effusion, radiography revealed an enlarged cardiac silhouette with a bulge in the area of the body of the right atrium. Echocardiography revealed an anechoic chamber-like cavity lateral to the right atrium that communicated with the right atrium through a 13 m...
Automatic segmentation of the heart's left atrium offers great benefits for planning and outcome evaluation of atrial ablation procedures. However, the high anatomical variability of the left atrium presents significant challenges for atlas-guided segmentation. In this paper, we demonstrate an automatic method for left atrium segmentation using weighted voting label fusion and a variant of the ...
این مطالعه در نظر دارد تا استحکام برشی 4 نوع سیستم چسبنده عاجی موجود در بازار را مقایسه کند. چهار نوع چسب عاجی شامل: 1-cleafil-se bond(kuraray) 2-etch&prime 3.03-excite single component(vivadent) 4-single bond(3m) است.
INTRODUCTION AND OBJECTIVES The left atrium is clinically relevant in patients with mitral valve stenosis. The objective of this study was to analyze the effects of percutaneous balloon valvuloplasty on left atrium volumes and the left atrium emptying fraction in symptomatic mitral valve stenosis patients using 2-dimensional and real-time 3 -dimensional transthoracic echocardiography. METHODS...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013008971 DESCRIPTION A 75-year-old female patient was admitted to our hospital presenting with episodes of exhausted chest pain for 2 years. A continuous murmur was heard over the precordium. The repeated ECG and echocardiograms were normal. At cardiac catheterisation, a left-to...
