title: Thrombosed aneurysm of the left sinus of Valsalva.
abstract: The authors present the case of a 57-year-old asymptomatic woman, in whom a large left coronary sinus of Valsalva aneurysm was incidentally diagnosed on a routine echocardiogram in 1998. The case was initially presented to cardiac surgery consultants, and since there were no signs of rupture and the patient was asymptomatic, it was decided to keep her in close clinical and echocardiographic follow-up. Eight years later, and with no clinical manifestation in the meantime, a transesophageal echocardiogram (TEE) showed that the aneurysm was filled with swirling spontaneous echo contrast ("smoke") overlying a thrombus, which was not detected by transthoracic echocardiography. The patient then underwent surgical treatment with aortic root and aortic valve replacement and coronary reimplantation, with an excellent result. Although the need for early surgical intervention in patients with ruptured sinus of Valsalva aneurysms is well established, the optimal management of an asymptomatic, unruptured aneurysm is less clear, due to the absence of a precise natural history. The follow-up of our patient clearly demonstrated that it is mandatory to assess unruptured sinus of Valsalva aneurysms by TEE, particularly to exclude thrombotic complications. Such complications are one of the possible paths of the natural history of unruptured sinus of Valsalva aneurysms, and support the indication for early surgical treatment to avoid future complications.
