left atrial mechanics in hypertensive patients

The relation between left ventricular geometric patterns and left ventricular midwall mechanics in hypertensive patients.

To evaluate the alteration of myocardial contractility in hypertensive patients with different left ventricular geometric patterns by the end-systolic stress-midwall fractional shortening relation. Echocardiography was applied to study the left ventricular geometry and cardiac function among 117 cases of essential hypertension, with 45 normal cases as control(s). Left ventricular mass index (LV...

comparison of left atrial function between hypertensive patients with normal atrial size and normotensive subjects using strain rate imaging technique

A 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...

Left Atrial Myxoma in Children: A Case Report

Un gargon de 13 ans fut hospitalise dans le Service de Pediatrie du C.H.U. de Pahlavi de la Faculte de Medicine de Teheran, pour une insuf­fisance cardiaque. Les signes auscultatoires, radiologiques et electriques evoquaient une stenose mitrale. Le malade deceda <lans le tableau d'oedeme pulmonaire aigli, apres quel­ques episodes d'hemiparesies resolutives.  A l'autopsie, il existait un myxcme...

Left atrial volume combined with atrial pump function identifies hypertensive patients with a history of paroxysmal atrial fibrillation.

Identifying patients at high risk for the occurrence of atrial fibrillation is one means by which subsequent thromboembolic complications may be prevented. Left atrial enlargement is associated with progression of atrial remodeling, which is a substrate for atrial fibrillation, but impaired atrial pump function is also another aspect of the remodeling. Our objective was to differentiate patient...

Left Atrial Myxoma: A Rare Tumor in a Child

Atrial myxomas are uncommon in the pediatric population but are very important due to pursuant atrioventricular valve obstruction and systemic embolic events. Concerning multiple symptoms ranging from congestive heart failure to neurological deficits, the diagnosis of this disease is complicated. This paper reports a case of left atrium myxoma in a child treated with a surgical excision o...
