Several minutes later he returns to consciousness and is able to continue playing. This has happened several times before with similar outcomes. He had no significant past medical history. Which of the following is most likely to be found in this patient?? A: Atheromatous plaque rupture, B: Coagulation necrosis with loss of nuclei and striations, C: Septal hypertrophy, D: Postductal coarctation of the aorta, E: Cardiac myxoma,  <response>: This is a case of a young athlete who is experiencing sudden, transient losses of consciousness during exercise. The key findings are that he is collapsing during strenuous activity, temporarily loses consciousness, and is able to resume activity afterwards. This presentation is most consistent with a cardiac arrhythmia caused by an underlying electrical conduction abnormality in the heart. Choice A, atheromatous plaque rupture, is incorrect because this patient is too young to have significant atherosclerotic disease. Choice B, coagulation necrosis, does not explain the transient loss of consciousness. Choice D, coarctation of the aorta, would cause hypertension, not syncope. Choice E, cardiac myxoma, is a benign tumor that would not cause transient syncope. Choice C, septal hypertrophy, is the most likely diagnosis. This refers to hypertrophic cardiomyopathy, a disease caused by abnormal thickening of the heart muscle that can obstruct blood flow and lead to arrhythmias. The transient loss of consciousness in a young athlete is classic for hypertrophic cardiomyopathy.C: Septal hypertrophy
