Transluminal closure of patent ductus arteriosus: long-term results of 208 cases treated without thoracotomy.

Patent ductus arteriosus was the first inborn cardiac defect ever eliminated by percutaneous transvascular therapy. The method, results, and complications of Ivalon plugging of the ductus in 208 patients between 5 and 62 years old and treated between 1967 and 1985 are described. Permanent closure was accomplished in 197 patients (94.

[Measurement of left ventricle asynergy by various measuring procedures. II. Findings in patients with post-infarction states].

In 30 patients with postinfarction condition (11 infarctions of the posterior wall, 11 infarction of the anterior wall, 8 aneurysms of the anterior wall) the regional contraction of the left ventricle was analysed by 3 different metrical methods (semiaxis, surface and angular method) on the basis of the kineventriculogramme in the 1st oblique diameter. With all 3 methods a significant reduction of the mean contraction amplitude could be proved in the affected ventricular region. Using the semiaxis method, in all 30 patients an asynergy could be identified.

[Evaluation of asynergies in the left ventricle using various metric methods. I. Findings in patients with normal heart function].

The delimitation of regional disturbances of contraction of the left ventricle (asynergies) demands knowledge of the behaviour of the contraction of the normal left ventricle. For the exact recognition of asynergies and for scientific inquiries in these cases the use of objective metrical methods is necessary. Therefore, in 14 patients without organic heart disease the behaviour of the regional contraction of the left ventricle was determined on the basis of the cineventriculography according to three different metrical methods (semiaxis, surface and angular method).
