introduction cardiac hydatid cysts are rare and represent less than 2% of all hydatid cases. they can occur as part of a widespread systemic infection or an isolated event. case presentation here, we presented a case of cardiac hydatid cyst in interventricular septum. conclusions the case presented had some findings that suggested the specific diagnosis of hydatid cyst.

There are frequent citations in the literature stating that lesions of the tendinous cords cause functional disorders of the heart valves. This led us to conduct the present investigation on the anatomy of the tendinous cords. Our objective was to focus on the morphological characteristics of tendinous cords that are inserted directly into the interventricular septum, such as their frequency, n...

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...

Endomyocardial biopsies in heart transplant patients offer the opportunity to study the myocardial interstitium in the context of myocardial function. For that purpose endomyocardial biopsies should reliably reflect the composition of the entire myocardium. We determined whether the collagen content in the subendocardial region of the right side of the interventricular septum (site of right ven...

BACKGROUND Intramural septal idiopathic ventricular arrhythmias have not been described systematically. METHODS AND RESULTS In a consecutive group of 93 patients with idiopathic ventricular arrhythmias referred for ablation, the site of origin of ventricular arrhythmias was assessed by activation mapping and pace-mapping. In 7 of 93 patients (8%), an intramural focus in the interventricular s...

The aim of this study was to investigate the contribution of direct right-to-left ventricular interaction to left ventricular filling and stroke volume in 46 patients with pulmonary arterial hypertension (PAH) and 18 control subjects. Stroke volume, right and left ventricular volumes, left ventricular filling rate, and interventricular septum curvature were measured by magnetic resonance imagin...

account for the increase in both VF and acute HF risk in patients presenting with STE in lead V4R. The interventricular septum is nown to play an important role in arrhythmias after myocardial nfarction (1). Morita et al. (2) demonstrated that acute ischemia f the interventricular septum in canine cardiac wedge preparations roduced asymmetric suppression of conduction velocity in the eptum, and...

Atrioventricular conduction disorders can appear after the implantation of percutaneous aortic CoreValve(®) prostheses in patients requiring permanent pacemakers (40%-45% of these patients). The aim of our study was to detect if 2- or 3-dimensional echocardiographic variables could predict the appearance of atrioventricular conduction disorders. For this purpose, the relationship of the prosthe...

Diastolic bulging of the interventricular septum (IVS) toward the left ventricle was observed by real-time cross-sectional echocardiography in three patients with primary pulmonary hypertension and one patient with secondary pulmonary hypertension after closure of an atrial septal defect. M-mode echocardiography showed a characteristic abnormal pattern of septal motion in diastole and in systol...

T he patient was an asymptomatic 33-year-old woman who had tuberous sclerosis with heart involvement. Her transthoracic echocardiogram showed multiple intramyocardial homogeneous masses in the left ventricle, the largest being 19 × 15 mm in the interventricular septum (Figure 1), and normal biventricular systolic function. Computed tomography showed images in the interventricular septum with a ...
