Aneurysm sinus of Valsalva, is relatively rare, attentive in approximately one person in each thousand. Aneurysm sinus of valsalva is caused by a dilation, usually of a single sinus of valsalva, from a separation between the aortic media and the annulus fibrosus. Other sickness processes which involve the aortic root can produce also.Aneurysm sinus of valsalva, although this usually involves multiple sinuses. Rupture of the dilated sinus may lead to intracardiac shunting when a communication is established with the right atrium or directly into the right ventricle. If unruptured, this type aneurysm may be asymptomatic and therefore go undetected until symptoms appear or medical imaging is performed for other reasons. Alternatively, patients may remain asymptomatic or have an insidious onset of symptoms.

This type of aneurysm is typically congenital and may be associated with heart defects. This is distinct from the diffuse dilatation of all sinuses seen in patients with connective tissue disorders. These aneurysms are usually congenital but may follow, or lead to, bacterial endocarditis. It is sometimes may also result from Ehlers-danlos syndrome, atherosclerosis, syphilis, cystic medial necrosis, chest injury, or infective endocarditis. Symptoms may develop by means of several mechanisms. The Aneurysm sinus of valsalva may function as a space-occupying lesion and thereby obstruct the left or right ventricular outflow tracts, interfere with aortic valve function, distort the coronary ostia with ischemic consequences, or compress the conducting system, resulting in conduction disturbances.

Although seldom necessary, is possible the definite diagnosis by performing a retrograde thoracic aortography or cardiac catheterization. To infer it from left to right can be also shown as the aneurismasinus of Valsalva is broken. Medical therapy of aneurysm of the aortic sinus includes blood pressure control through the use of drugs, such as beta blockers. The definitive treatment is surgical repair. The determination to perform surgery is usually based upon the diameter of the aortic root and the rate of increase in its size, as determined through repeated echocardiography. More commonly, sinus of Valsalva aneurysms are diagnosed after clinical sequelae of rupture. Diagnosis of sinus of Valsalva aneurysm is facilitated by echocardiography, contrast aortography, and more recently, magnetic resonance imaging. Repair is generally required for ruptured aneurysms, unruptured aneurysms encroaching on nearby structures, causing myocardial ischemia, or having the potential to rupture warrant repair.
