Eleven cases of double inlet left ventricle have been presented. Double inlet left ventricle is characterized by the tricuspid valve opening partly (partial type) or completely (complete type) into the morphological left ventricle. The morphological right ventricle is usually hypoplastic but may be normally formed. Even when the right ventricle is hypoplastic, both the sinus and the outflow por...

Dehydroepiandrosterone (DHEA) prevents chronic hypoxia-induced pulmonary hypertension and associated right ventricle dysfunction in rats. In this animal model, reoxygenation following hypoxia reverses pulmonary hypertension but not right ventricle dysfunction. We thus studied the effect of DHEA on the right ventricle after reoxygenation, i.e. after a normoxic recovery phase secondary to chronic...

IN CHRONIC CARDIAC DISEASE, the left ventricular diastolic pressure does not provide a reliable guide to the diastolic left ventricular volume,' and measurement of chamber volume, shape and wall thickness are necessary to identify changes in the myocardial stress-strain relation.' Under acute conditions, the stiffness of the left ventricular chamber progressively increases as passive diastolic ...

Echocardiography was performed on 5 patients with extracardiac masses. Four patients had solid tumours and the fifth had a cystic intrapericardial haematoma. Case 1 showed dense echoes anterior to the aortic root and over the right ventricle. Thoracotomy disclosed malignant infiltration ofthe anterior heart wall. The echocardiogram of case 2 showed a dense mass behind the anterior mitral leafle...

Knowledge about the role of the right ventricle in health and disease historically has lagged behind that of the left ventricle. Less muscular, restricted in its role to pumping blood through a single organ, and less frequently or obviously involved than the left ventricle in diseases of epidemic proportions such as myocardial ischemia, cardiomyopathy, or valvulopathy, the right ventricle has g...

During exercise, the right ventricle is exposed to a disproportionally higher wall stress than left ventricle, which further exaggerated under hypoxia. In this study, we showed that 12-wk high-intensity running hypoxic exercise training induced right-sided structural remodeling, was, in part, related baseline cardiac increase RV fractional area change acute exercise. These data suggest response...

Fig. 1. Coronal view of a re-formatted CT scan image with contrast showing the right ventricle (RV), left ventricle (LV), and a pericardial haematoma (PH). ‘L’ represents the level of the rupture of the myocardial abscess and its connection to the pericardial space. Fig. 2. CT 3-D reconstruction with contrast showing the right ventricle (RV), left ventricle (LV), and the pericardial haematoma (...

The water, nitrogen, and electrolyte content of the normal canine myocardium partitioned as right ventricle, septum, and left ventricle are presented on a connective tissue-free basis as well as fat-free and blood-free. Considering the tissue on a fat-free, blood-free, connective tissue-free basis, the extracellular phase (expressed as g/kg heart muscle) of the left ventricle was 86% that of th...
