[An unusual cause of syncope in hypertrophic cardiomyopathy].
Syncope and pre-syncope represent common symptoms in patients with hypertrophic cardiomyopathy. The clinical scenario of recurrent and frequent syncopal episodes is one of the most challenging in the management of patients with hypertrophic cardiomyopathy. Syncope in hypertrophic cardiomyopathy patients usually recognizes two underlying mechanisms: arrhythmias or primary hemodynamic mechanism. The concomitant presence of myocardial ischemia is one of the potential triggers in the context of syncope due to hemodynamic mechanism. Myocardial ischemia is not generally related to epicardial coronary artery atherosclerotic disease but rather to the presence of partially obliterated intramural coronary arteries or narrowed vessels. We report the rare case of a patient with hypertrophic cardiomyopathy presenting with recurrent syncopal episodes due to myocardial ischemia secondary to severe stenosis of the left anterior descending coronary artery.
