Rapid expansion of mycotic aneurysm of left coronary sinus of Valsalva causing myocardial ischemia: report of a case.

We described a 71-year-old female of aneurysm of the left sinus of Valsalva from mycotic origin. She underwent aortic valve replacement 11 years ago. Repeated CT scans showed rapidly growing aneurysm below the left coronary ostium. On sixth day after the admission, she suddenly developed myocardial ischemia complicated with ventricular fibrillation. The patient was treated with emergent aortic root replacement and she recovered. We recommend emergent surgical repair of mycotic saccular aneurysm of the left sinus of Valsalva because a delay of surgery could be fatal.
