    It is medieval Transylvania and the peasants have finally revolted against the rule of the evil and tyrannical Count Vlad (the Impaler). Driving a wooden stake into the sleeping count's chest at the sternal angle (of Louis), they hope to pierce the left ventricle of his heart. They miss. Why?

    The patient, Harry, was 58 years of age and obviously very overweight. He was admitted to the hospital complaining of severe, crushing, retrosternal pain which he said began while he was jogging in his neighborhood. The pain has not gone away after taking three nitroglycerine tablets, and the pain has lasted longer than when he had last experienced an anginal attack. His skin is clammy and unusually cool, his heart rate is 120 per minute. Laboratory results show that his mitral valve is not functioning properly because of ischemia of the posterior aspect of his left ventricle and his left posterior papillary muscle. From your previous knowledge of the patient's coronary arterial pattern as being "left coronary dominant," you make the correct guess that

      The left coronary circumflex artery is blocked by disease(fatty and calcified atherosclerotic plaque).

    • B. 

      The right coronary artery supplies the posterior one third of the IVS.

    • C. 

      The LAD is almost completely closed, probably just beyond the origin of the first major branch to the IVS.

    • D. 

      The conus artery is totally occluded.

    • E. 

      The moderator band of the left ventricle has become ischemic.
