A 69-year-old gentleman presented with sudden-onset dizziness and diplopia. Clinical examination findings were suggestive of posterior circulation stroke. He was found to be in atrial flutter on admission, reverting spontaneously to sinus rhythm. Three weeks before admission, he was admitted to a different hospital with anterior circulation Figure 1 (A) Transthoracic echocardiogram (PLAX view) ...

To test the hypothesis that the ventricular septum moves during systole toward the center of ventricular mass (so that the end-diastolic position of the septum within the heart should determine both the direction and the magnitude of septal motion during systole), echocardiograms from patients with several different hemodynamic burdens were analyzed. A linear relation was noted between the end-...

OBJECTIVE To evaluate the structure-function relationships of the right ventricle (RV) and septum and determine if the helical ventricular band model would define fiber orientation for maximal force response. Implications were made for right ventricular function. METHODS The right ventricular free wall and biventricular septum were studied by inserting sonomicrometer crystals at different ang...

BACKGROUND We aim to deliver large appliances into the left ventricle through the right ventricle and across the interventricular septum. This transthoracic access route exploits immediate recoil of the septum, and lower transmyocardial pressure gradient across the right versus left ventricular free wall. The route may enhance safety and allow subxiphoid rather than intercostal traversal. MET...

The roles of posterior bulging of the interventricular septum (septal bulge) and of systolic septal mitral apposition in patients with simple transposition of the great arteries are not known. Cross sectional echocardiograms of 40 such patients were reviewed (after exclusion of those with fixed left ventricular outflow tract obstruction) and haemodynamic findings were compared with long and sho...

A 76-year-old woman with sarcoidosis who had an implantable pacemaker for complete atrioventricular block was admitted with syncope. Electrocardiogram revealed ventricular pacing failure, and a marked rise in the ventricular pacing threshold. 18F-Fluorodeoxyglucose positron emission tomography (FDG-PET) indicated increased uptake of FDG in the ventricular septum. Three days after steroid therap...

A Chinese woman was admitted to our hospital because of syncope. Transthoracic echocardiography revealed a hypertrophic basal interventricular septum of 15 mm with a sharp angle protruding into the left ventricular outflow tract. Moreover, an anomalous anterolateral papillary muscle (maximum width of 11 mm) was inserted into the left ventricular outflow tract, with short chordae tendineae conne...

Described herein is a 68-year-old man who underwent cardiac transplantation for severe chronic heart failure resulting from ischemic cardiomyopathy. Examination of the excised heart showed not only extensive left ventricular scarring but also a huge collection of adipose tissue in the subepicardial region and surprisingly also in the ventricular septum. The finding of fat in the ventricular sep...

Double-outlet right atrium (DORA) is characterized by simultaneous right atrial emptying into both ventricles. Ventriculoatrial septal malalignment is the cardinal morphological feature. Three cases are presented to depict two major types of DORA-DORA with a malaligned atrial septum and DORA with a malaligned ventricular septum. We describe two subtypes of each form of DORA: DORA with a malalig...

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...
