background: several echocardiographic markers have been introduced to assess the left ventricular (lv) mechanical dyssynchrony. we studied dyssynchrony markers and the latest lv activation site in heart failure patients with and without left bundle branch block (lbbb). methods: conventional echocardiography and tissue velocity imaging were performed for 78 patients (lv ejection fraction ≤ 35%),...

ECG diagnosis of a posterior wall myocardial infarction is difficult to diagnose through the standard 12 lead ECG, especially in the acute stage. The posterior wall MI may occur as an isolated event or often associated with an inferior wall myocardial infarction Posterior leads V7, V8 and V9 are usually ignored but it is suggested that these leads can provide ECG information that is useful for ...

To assess regional contractility in idiopathic hypertrophic subaortic stenosis (IHSS), a primary myopathic disorder with documented hyperdynamic ventricular contractions, systolic wall thickening and velocity of contraction of the septum and left ventricular posterior wall were measured in echocardiograms from 16 patients with IHSS and 16 normal subjects. The average thickening of the normal se...

Introduction: The horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (PSAa) and the infraorbital artery. This anatomic structure is known as the ‘alveolar antral artery’.   Materials and Methods: We performed a literature review. The anatomic location of the alveolar antral artery in the latera...

Echocardiograms were recorded in 154 active athletes (from various sports) and 21 ex-athletes and compared with those in 40 normal control subjects (non-athletes). Diastolic cavity dimension and posterior wall and septal thickness were measured and left ventricular mass and the ratio of posterior wall thickness to cavity radius and of septum to posterior wall thickness calculated. As a group at...

There are situations which the tomographic exam is done on the affected hip or situations where the contralateral hip presents abnormalities that make it impossible to compare. In this study we aimed to evaluate a tomographic index that does not require comparison between the both hips. Twenty two patients with unilateral acetabular fracture dislocation with fracture of posterior wall were stud...

left ventricular free wall rupture is responsible for up to 10% of in-hospital deaths following myocardial infarction. it is mainly associated with posterolateral myocardial infarction, and its antemortem diagnosis is rarely made. one of the medical complications of myocardial infarction is the rupture of the free wall, which occurs more frequently in the anterolateral wall in hypertensives, wo...

In the treatment of posterior wall fractures of the acetabulum, a modified distal radius T-plate can be substituted for one third tubular spring plates for fixation of thin, small, or comminuted posterior wall fragments. This technique is described as well as a case series of 33 patients with various posterior wall acetabular fractures.

It is difficult to distinguish between restrictive cardiomyopathy and constrictive pericarditis on the basis of clinical findings and simple investigation. Cardiac catheterisation has been the reference standard for diagnosis but even this does not always permit an accurate distinction. A Summagraphics digitiser and Prime 750 computer system were used to digitise the echocardiograms of 15 patie...

M-mode indices of left ventricular dimension and posterior wall thickness were derived from echocardiograms of children presenting with dilated cardiomyopathy/myocarditis and were related to outcome. Echocardiograms from 16 of 18 children were manually digitized to obtain changes of left ventricular dimension and posterior wall thickness throughout the cardiac cycle. Indices of ventricular func...
