Extreme Left Atrial Enlargement
ENLARGEMENT of the left atrium is well known as one of the earliest manifestations of rheumatic mitral valvular dysfunction. On rare occasions this chamber may become enormous, expanding to the right and posteriorly to form a huge sac that encroaches upon adjacent structures and may eventually rest against the right chest wall. The clinical course of patients who develop such extreme left atria...

متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملElectrocardiographic detection of left atrial enlargement. Correlation of P wave with left atrial dimension by echocardiography.
The validity of various electrocardiographic P wave measurements was tested in 48 patients by comparing them to left atrial dimensions determined by echocardiography (echo), a proved method of left atrial size estimation. Of all the measurements considered, only the width of the P wave (PW), the P terminal force in lead V1 (PV1), and the PW/PR segment ratio (PW/PR) showed statistically signific...
متن کاملDiscrepancies in Identification of Left Atrial Enlargement Using Left Atrial Volume versus Left Atrial‐to‐Aortic Root Ratio in Dogs
BACKGROUND Left atrial size is prognostically important in dogs with myxomatous mitral valve disease (MMVD). HYPOTHESIS/OBJECTIVES To compare the level of agreement in identification of left atrial enlargement (LAE) between the left atrial-to-aortic root ratio (LA : Ao) and left atrial volume using the biplane area-length method indexed to body weight (LA Vol/BW). ANIMALS Sixty dogs with MM...
