[X-ray cinematographic studies of local ventricular dynamics after aortocoronary bypass]. / Röntgenkinematografische Studien der lokalen Ventrikeldynamik nach aorto-coronarem Bypass.

ABSTRACT

In 12 patients with high-grade coronary stenosis local motility before and after aortocoronary vein bypass was estimated by cineradiography of coronary bifurcations and surgically implanted myocardial metal markers. A group of patients with relief of angina showed significant increase of local segment shortening within the first postoperative days. During the following months no further alteration occurred. In three patients with persisting angina no improvement of local motility could be found.
