A 54-year-old man, ex smoker with high blood pressure and a history of possible Wolff-Parkinson-White syndrome was admitted for presenting an episode suggestive of acute coronary syndrome with immediate syncope and left bundle branch block, while performing physical activity. Angioplasty and a drug-eluting stent were performed in the left circumflex artery. Subsequently, Doppler echocardiography disclosed an image suggestive of a subaortic membrane. Given these findings, the patient underwent a 3D transesophageal echocardiogram and a magnetic resonance study, which confirmed the diagnosis of a subaortic membrane. In turn, in the Holter monitoring a paroxysmal pattern of Wolff-ParkinsonWhite was observed. The patient presented three possible causes of syncope. A stress echocardiogram elicited a gradient of 126 mm Hg, which could be possibly related to the syncopal episode that the patient suffered.
