Abstract: | Two patients are presented in whom severe calcific aortitis made performance of satisfactory proximal coronary anastomosis impossible. Endarterectomy of the ascending aorta after aortic valve replacement, combined with aortocoronary bypass prior to performance of the proximal anastomoses, was successfully employed in one patient. The second patient underwent resection of an anterior segment of aorta, which was replaced by a woven Dacron patch into which the vein grafts were sewn. |
