Aneurysm of aortic sinus: preview of literature and clinical case.

Abstract

Aneurysm of aortic sinus (AAS) is rare congenital or acquired disease with various clinical presentation. The most severe complication is rupture of the aneurysm which can lead to communication with a cardiac chamber. The enlargement of the aneurysm can cause a coronary artery compression. A rupture to pericardial sack will give a rise to pericardial tamponade which is condition with poor prognosis.

  Transthoracic echocardiography (TTE) is method of choice for diagnosing aneurysm of aortic sinus. This imaging modality permits assessment of anatomy of the dilated aortic sinus and the color doppler allows visualization of a shunt in case of rupture and communication with a cardiac chamber.

   The surgical treatment is method of choice. There are different techniques for correction of the dilated sinus in order to preserve the coronary ostia. The interventional technique uses occluding devices. This method is innovative, with excellent results and it’s gaining more popularity. 

In the present article we describe a rare form of right coronary sinus aneurysm in young male resulting in compression of right atrium and right coronary artery which first clinical presentation was atrial fibrillation.
