and hemodyhamic features of five cases of surgically proved complete absence of the atrial septum are presented. Technical details of the method of correcting this malformation are described. At foUow up, all are alive and well. It is suggested to subdivide this entity into two: single atrium, when complete absence of the atrial septum is found but the atrioventricular valves are normal, and co...

Single atrium (SA) is a rare congenital anomaly characterized by absence or virtual absence of atrial septum, vestigial remnant of which occasionally remain. We report here such a case of SA who presents his symptoms in different way of its natural course of presentation.

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 ...

conclusions a right atrium myxoma in a patient with a history of multiple soft tissue tumors has been limited to only a few cases. this may suggest a genomic affinity or similarity; if so, those with multiple different type soft tissue masses should be screened for a heart mass before the mass becomes complicated. introduction heart secondary tumors are much more common than primary tumors. the...

Dual-chamber (DDD) pacing for maintenance of atrioventricular (AV) synchrony generally requires the implantation of two leads, one in the right atrium and one in the right ventricle. During the early 1990's, the efforts were made to achieve DDD pacing using only one lead [1-3]. The idea was to use the electrical field generated between the floating ring electrodes located in the right atrium to...
