Case ReportsIdiopathic aortitis with calcification of ascending aorta, and aortic and mitral valves.
A young woman with unexplained radiographic calcification of the ascending aorta was found at necropsy to have healed idiopathic aorititis. Calcification also involved the aortic valve which was stenosed and the mitral valve. Death was the result of infective endocarditis of these valves with aortic ring abscess, rupture of aortic root, and cardiac tamponade.

Serial 3 orthogonal lead electrocardiographic abnormalities after pulmonary embolism. Computer assisted study.
The 3 orthogonal lead electrocardiogram has been evaluated with computer assisted interpretation in 20 patients with acute pulmonary embolism confirmed by pulmonary angiography. Initial 3-lead electrocardiographic abnormalities were found to be at least as helpful as the 12-lead electrocardiogram in supporting the clinical diagnosis. In addition, however, sequential changes in both the maximum QRS and T vector orientations in frontal and transverse planes were more often apparent than any sequential changes in the 12-lead electrocardiogram. While no specific 3 lead electrocardiographic criterion for pulmonary embolism could be determined, this technique was more helpful than conventional methods in following serial electrocardiographic changes in patients with this condition.
