%X A 49-year-old woman, without known cardiovascular risk factors. Hoarseness of voice caused by a paralysis of left vocalcord. She was admitted to hospital because of acute coronary syndrome, associated to resuscitated cardiac arrest (asystoliadocumented) without later neurology sequels. Physical examination was anodyne. Echocardiographic study demonstrated acompatible image with a large left sinus of Valsalva aneurysm (SVA) (Panel A) and mild aortic regurgitation. Cardiac catheterizationconfirmed the presence of left SVA (Panel B) that produced extrinsic compression of the left main coronary artery (Panels C and D). Repair surgery was made by means of closingthe aneurysmal orifice with a patch of dacron. Intra-operatory echocardiographic control study found severe aortic regurgitation, so valvular replacement with 19 mm mechanical prosthesis and extension of the valve annulus with patch of dacron wasperformed, associated with bypass with safena vein graft to left coronary artery.SVA is a very infrequent cardiac anomaly, generally with silent clinical course until it ruptures. Myocardial ischaemia caused bycoronary artery compression is unusual. We described the case of a patient diagnosed of left SVA, whose initial clinical manifestation was the appearance of resuscitated sudden cardiac death in the context of an acute coronary syndrome.
