What is sinus of Valsalva aneurysm?
Introduction. Sinus of Valsalva aneurysm (SOVA) is an abnormal dilatation of the aortic root located between the aortic valve annulus and the sinotubular junction. This occurs as a consequence of the weakness of the elastic lamina at the junction of the aortic media and the annulus fibrosis.
What are the clinical features of a ruptured sinus of Valsalva?
An aneurysm of the sinus of Valsalva ruptures in 35%, leading to acute symptoms in one fourth of the patients. Symptoms associated with rupture are shortness of breath, chest pain, and fatigue. The severity of the shunt, the presence of associated lesions, and age at presentation determine the severity of symptoms.
Where is the sinus of Valsalva?
The sinuses of Valsalva, also known as aortic sinuses, are the anatomic spaces at the aortic root bounded internally by the aortic valve leaflets and externally by outward bulges of the aortic wall.
What is normal sinus of Valsalva?
The normal diameter size of sinuses of Valsalva is 29–40 mm (18 ± 2 mm/m2) as it is included in the figure below. The authors apologize for this error.
What is the right sinus of Valsalva?
An aortic sinus, also known as a sinus of Valsalva, is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve. These widenings are between the wall of the aorta and each of the three cusps of the aortic valve….

Is sinus of Valsalva aneurysm congenital?
Primary causes of sinus of Valsalva aneurysm (SVA) are congenital. Secondary causes include the following: Atherosclerosis.
What originates from the aorta at the sinuses of Valsalva?
Which is the correct sinus for Valsalva aneurysm?
1. SINUS OF VALSALVA ANEURYSM Moderator- Dr.RV KUMAR Presenter- Dr.Jyotindra Singh 2. INTRODUCTION Thin walled, saccular or tubular outpouchings, usually always in the right sinus or adjacent half of the noncoronary sinus.
Why was the Valsalva 3 sinus named after?
SINUS OF VALSALVA 3 sinuses named after- Antonio Valsalva. Provide space behind the open aortic leaflets so that the leaflets do not occlude the coronary artery orifices. Secondly, this space favours the development of eddy currents behind the leaflets when they are open.
Which is the most common receiving chamber for an aneurysm?
ANEURYSM RUPTURE Ruptured aneurysms originate most frequently from the right coronary sinus (65–85%), Less frequently from the noncoronary sinus (10–30%), and Rarely from the left coronary sinus ( 5%) The right ventricle is the most common receiving chamber (about 80–90%), due to rupture of either right or noncoronary SVA 20.
What is the normal size of the sinus?
The function of the normal sinuses is to prevent occlusion of the coronary artery ostia during systole when the aortic valve opens. The normal sinus diameter is less than 4.0 cm for men and 3.6 cm for women.
