| pubmed-article:7197017 | pubmed:abstractText | The right anterior oblique ventriculographs of 20 patients with obstructive cardiomyopathy were reviewed, and the images obtained during systole were divided into three groups: (1) bilocular left ventricular cavity with midventricular stenosis; (2) obliteration of the ventricle reduced to its infra-sigmoidal portion, with atrophy or even amputation of the apical portion; and (3) subnormal image. Haemodynamically, the most common abnormality (5/8 patients) in group 1 was the presence of a gradient in the basal state. In group 2, this gradient was only found in 2/8 patients, but the left ventricular telediastolic pressure was much higher in the basal state or after stimulation than in group 1. Haemodynamic changes were moderate in group 3. The abnormalities in left ventricular telediastolic pressure in this type of cardiomyopathy are interpreted as reflecting disorders in compliance which would then be maximal in group 2. This study is part of an attempt to classify the various characteristics of the left ventricle with the view of identifying some forms amenable to surgical treatment. | lld:pubmed |
