ABSTRACT
This chapter presents a case study of a 71-year-old white woman, had been asymptomatic all her life until she suddenly collapsed on the tennis court. She was resuscitated, transported to a hospital, where she failed to regain consciousness until her death 8 days later when life support was withdrawn. During a routine examination when she was 64 years old, an electrocardiogram disclosed complete left bundle branch block. Coronary angiogram was recorded at the time and no narrowings were present in the epicardial arteries and no abnormalities in origin or courses of the coronary arteries were noted. At necropsy, the heart weighed 305 g. The major epicardial coronary arteries had normal origins and courses with a right dominant circulation. The arteries were cut transversely at 5 mm intervals, and although an occasional small plaque was present, the lumen everywhere was wide open.
