Echocardiogram (Figure 2) showed right ventricular inflow tract stenosis causing an intraventricular gradient of 80 mmHg, with a 13-mm diameter ventricular septal defect partially occluded by the tricuspid valve, thus resulting in an effective 4.7-mm orifice. There was RV hypertrophy with mildly enlarged right cardiac chambers. Gradient between ventricles was 82 mmHg. There was a small aneurysm...

BACKGROUND The spread of activation between the right atrium (RA) and left atrium (LA), particularly along the right and left aspects of the interatrial septum, is not clear. METHODS AND RESULTS Basket-shaped catheters carrying 64 electrodes were deployed into both the RA and LA of 10 dogs. Position and orientation of the baskets were determined by fluoroscopy and echocardiography. Basket uni...

Background In theory, movement of the septum contributes to left ventricular stroke volume (LVSV) if the movement is toward the left ventricle (LV) in systole. If the septum movement is toward the right ventricle (RV), as in dyssynchrony, the septal contribution to LVSV decreases. In patients with increased volume load of the RV the septum may move towards the RV and contribute to right ventric...

Conspicuous left axis deviation was found in two thirds (27 patients) of 44 children with a perimembranous ventricular septal defect, echocardiographic signs of apposition of the septal tricuspid valve leaflet, and an aneurysm of the membranous septum. In 10 patients earlier electrocardiograms did not show left axis deviation; this feature appeared when the aneurysm of the membranous septum was...

Background: Ventricular septal rupture is a rare but fatal mechanical complication of acute myocardial infarction. Although the incidence has decreased, the mortality rate from ventricular septal rupture has remained extremely high. Objectives: The aim of this study was to assess the patient with acute myocardial infarction complicating with ventricular septal rupture and to identify the risk f...

background: sickle-cell disease (scd) is an inherited hemoglobin childhood disorder, frequently complicated by pulmonary hypertension and cardiac involvement. cardiovascular events and complications are the leading cause of mortality and morbidity in patients with scd. tissue doppler imaging and the myocardial performance index (tei index), are simple indices for the assessment of the cardiac f...

A 47-year-old man presented as a dyspnea and fatigue. A transthoracic echocardiography (TTE) performed to assess valvar heart disease and left ventricular (LV) function showed a large hydatid cysts in the inter ventricular septum bulging to posterior of heart and compressing its overlying muscle as whitish round mass. The patient underwent elective surgery by evacuation of septal hydatid cysts ...

Right ventricular (RV) mid-septal pacing should have fewer negative effects on left ventricular function compared to apical pacing. However, targeting the mid-septum may be technically challenging since it is usually done with two-dimensional fluoroscopy. The rotation of the heart and various shapes of the RV make it difficult to assess, whether the lead is really anchored in the septum. Many l...

The anatomy of the membranous part of the ventricular septum is described in 25 hearts from patients ranging in age from 15 weeks of gestation to the ninth decade of adult life. Both atrioventricular and interventricular components were recognised in all the adult subjects, and the atrioventricular component was evident in all 25. The interventricular membranous septum was present in only 1 of ...

Left Ventricular Hypertrophy has a risk of increasing the brevity of the population if left untreated. Quantitative aid in the diagnosis and prognosis of Left Ventricular Hypertrophy to field experts is very essential to classify the disease and proceed treatment. Endocardium segmentation of left and right ventricles is done through Local Chan Vese Model using Radial Charge Fitting Curve. This ...
