Fi uax 1. Apical four-chamber views from preoperative two-dimensional echocardiogram showing dropout of interventriculan/septal echoes (left panel). Peripheral venous D5W injection (middle panel) at first opacifles only right atrium and ventricle, with no right-to-left shunt and possible left-to-right shunt as indicated by negative contrast effect in the right ventricle. With a premature beat, ...

We have analysed the atrioventricular junction, ventricular mass, and ventriculoarterial junction in 43 hearts with isomeric atrial chambers. Of the hearts, 32 had atrial chambers of bilateral right morphology while 11 had atrial chambers with bilateral left atrial characteristics. Among the hearts with right atrial isomerism, there were 13 biventricular hearts, all with ambiguous atrioventricu...

conclusions this study indicated that the rv systolic strain and strain rate can be used to detect early rv systolic dysfunction in ssc patients without pulmonary hypertension. these parameters may be useful for the provision of a more adequate management of ssc patients. results in the ssc patients, the rv strain (- 19 ± 10 vs. - 25 ± 4 %; p = 0.004) and the systolic strain rate (- 1.3 ± 0.5 v...

the present report describes a male newborn with a pulsatile structure beneath the sternum. echocardiography showed common atrium, a single ventricle, mitral atresia, double outlet right ventricle, subpulmonary stenosis, small pulmonary artery branches, and a thin walled ventricular diverticulum suggestive of cantrell's syndrome. the diverticulum was resected to prevent life threatening events ...

An angiographic analysis of 10 cases of univentricular heart of the right ventricular type is reported. This congenital malformation is characterized by a large chamber with right ventricular morphology that receives both atrioventricular valves, and a second, smaller chamber, a trabecular pouch, with left ventricular morphology. These chambers are separated by a posterior septum but are connec...

Cardiovascular abnormality is the most consistent finding and occur in almost 80 % of all Williams syndrome (WS). Although a number of cardiovascular defects are common to WS, the majority presents in some form of arterial stenosis whereas supravalvular aortic stenosis is the most common one. Here we describe a 12 year old boy with elfin facies, presenting with urinary incontinence and a systol...
