ANEURYSM of the membranous portion of the interventricular septum is an uncomrnon congenital cardiac malformation rarely diagnosed during life. To our knowledge the literature contains four previous cases.14 Two of these were confirmed at surgery,3' 4 the other two were visualized by angiocardiography alone.1 2 This is the report of an unusual case in which the aneurysm produced hemodynamically...

We present the case of a 64 year old man, previously of good health, who presented in November 1995 with a short history of presyncope and one witnessed episode of syncope.On admission he was clinically in complete heart block with a ventricular rate of 40 beats/min but had a well maintained blood pressure at 150/80 mm Hg. Auscultation revealed a soft systolic murmur in the aortic area. The rem...

BACKGROUND In this study, the angle of the myocardium's trajectory in three dimensions (ф) was estimated by simultaneous use of long-axis and short-axis views of left ventricle septum two-dimensional images. Then correlation of three-dimensional trajectory's angle with the rotation angle from the long (χ) and short (θ) axis views was estimated and compared at the three levels of base, mid and a...

Following a review of experimental methods used for the production of necrosis or inactivation of the myocardium, a new method employing low temperatures is described. Lesions, with complete necrosis of muscle cells, can be controlled as to size and can be selectively placed to involve any of the four cardiac chambers and the interventricular septum. This facilitates attempts to study chronic m...
