Localized aneurysms of the sinus of Valsalva are extremely rare. They may be congenital or acquired (as a consequence of trauma, degeneration, inflammation or infection).1

A 74-year-old man with hypertension, type 2 diabetes mellitus and dyslipidemia, was admitted in the emergency room after an episode of retrosternal chest pain and shortness of breath. Physical exam was unremarkable. The ECG showed ischemic T waves from V1 to V5 and the peak troponin I level was 0.5ng/ml. He was referred for coronary angiography, which demonstrated as unique pathologic finding left main extrinsic compression from an ovoid-shaped structure with turbulent flow of dye inside (Fig. 1; SVA – sinus of Valsalva aneurysm, LM – left main). Magnetic resonance imaging confirmed the presence of a left Valsalva sinus unruptured aneurysm below the left main, causing extrinsic compression (Fig. 2; AV – aortic valve). The ascending aorta was dilated and the aortic valve was bicuspid with mild aortic insufficiency. To avoid future life-threatening ischemic events and the possibility of enlargement and sudden rupture, cardiac surgery was performed. The operative findings revealed a 2.5cm diameter left aortic sinus aneurysm, just below the left main (Fig. 3). Repair was performed with aortic valve substitution by a bioprothesis and ascending aorta replacement by a dacron graft, with coronary ostium reimplantation. The postsurgical evolution was unremarkable.

Sinus of Valsalva aneurysms may imply high morbidity since they are prone to rupture.2 We report a clinical case of spontaneous aneurysm with unusual clinical presentation (NSTEMI), which had good outcome as a result of prompt diagnosis and surgery.
