This book deals with arteriography, microanatomy, and pathogenesis of coronary heart disease. The study was made by means of injection of the coronary system after death followed by stereoscopic visualization of the radiographic picture. A total of 59 cases was studied.

The findings of the author confirm the classic anatomical description. Atherosclerosis was almost always restricted to the epicardial branches; the anterior descending branch was often affected at the level of origin of its first main septal branch, where the stem was "anchored" to the myocardial wall.

In regard to coronary anastomoses, the findings of the author are in agreement with those of older workers and at variance with those of Schlesinger's group. The author concludes that the coronary arteries are not "end arteries" because numerous anatomoses of fine caliber are found at nearly all areas of the normal heart. The subendocardial plexus of the left ventricle represents an important
