Congenital aneurysms of the interventricular septum were found in a 29 year old man and his four year old son. Both were symptom free. In both, M mode and cross sectional echocardiography showed an aneurysm in the mid-muscular trabecular portion of the ventricular septum with considerable paradoxical motion of the aneurysmal segment. Otherwise the chamber dimensions, intracardiac structures, an...

Aneurysm of the sinus of Valsalva that causes dissection of the interventricular septum is an extremely rare entity. In this report we describe a case of aneurysm of the sinus of Valsalva dissecting into the interventricular septum, from the base to mid septum, after aortic valve replacement. After the diagnosis was made by transthoracic echocardiography and magnetic resonance imaging, the pati...

The clinical, echocardiographic, and catheterization findings in a patient with discrete subaortic stenosis, aneurysm of the membranous interventricular septum, and mitral valve prolapse are presented. Echocardiography showed a subaortic membrane, abnormal aortic valve motion, accentuated systolic anterior motion of the membranous interventricular septum, and prolapsing mitral leaflets. Cardiac...

Background & Aims: One of the important aims of quantitative cardiac image processing is the clarification of myocardial motions in order to derive biomechanical behavior of the heart in the disease condition. In this study we presented a computerized analysis method for detecting the instantaneous myocardial changes by using 2D echocardiography images. Methods: The analysis was performed on th...

This case report describes the distinctive echocardiographic pattern in a patient with a congenital right sinus of Valsalva aneurysm. The eChocardiogram demonstrated an abnormal structure extending from the aortic root into the left ventricular chamber adjacent to the interventricular septum. The structure showed diastolic motion away from the septum and systolic motion toward the septum. This ...

∗ Corresponding author. E-mail address: [email protected] (P. Rodrigues). The patient rapidly evolved with cardiogenic shock and a new systolic murmur. The echocardiogram revealed interventricular septal rupture with an extensive interventricular communication at the level of the posterobasal septum, associated with a serpiginous dissection of the septum, forming a neocavity, with an exit ...

Muttipolar recording techniques have been used to study excitation of the canine interventricular septum. Activity commences in the mid left septal endocardium and slightly later near the right anterior papillary muscle. From these sites depolarization spreads over the endocardial surfaces, probably via the Purkinje tissue, at 1 m./sec. and through the septal thickness at one-third this speed. ...

Right ventricular loading/pressure influences left ventricular function because the two ventricles pump in series and because they are anatomically arranged in parallel, sharing the common ventricular septum. Flattening of the interventricular septum detected during echocardiographic examination is called D-shaped left ventricle. We present a case of an elderly male of African descent, who pres...

BACKGROUND Intraseptal hematoma and subsequent myocardial infarction due to accidental contrast agent deposition complicating diagnostic cineventriculography is a previously undescribed complication of angiography. CASE PRESENTATION A 61 year old man was admitted at intensive care unit because of unstable angina pectoris 1 hour after coronary angiography. Transthoracic contrast echocardiograp...

Dissection of the interventricular septum (IVS) is an extremely rare entity. An institutional echocardiographic database was retrospectively reviewed; 13 patients with a diagnosis of IVS dissection were found and confirmed by cardiac surgery. The purposes of the study were: to determine the value of transthoracic echocardiography (TTE) in establishing the diagnosis of IVS dissection, and to det...
