Sinus of valsalva aneurysm is the least common type of all aortic aneurysms. The sinus of valsalva refers to a part of the heart that stems from the aorta and helps to keep the valves closed, preventing blood from going back into the chambers of the heart. An aneurysm in this region can either be congenital meaning present at birth, or acquired meaning it is secondary to another cause. Congenital sinus of valsalva aneurysms are rare. Secondary causes include clogged arteries (atherosclerosis), syphilis, and inflammation of the heart valves (endocarditis) due to infection. The large majority of aneurysms in this region are on the right side of the heart. If the aneurysm does not rupture, there are rarely any symptoms present. In congenital cases, the condition usually goes undetected unless medical imaging such as MRI, echocardiogram or CT scan is done for some reason. If an aneurysm does rupture, symptoms can include heart murmurs and heart failure. Ruptures rarely occur before the age of twenty. Treatment for this condition is usually blood pressure control through the use of beta-blockers or other drugs. Surgical repair on a non-ruptured aneurysm has a very good outlook. If you are experiencing any heart irregularities, please consult your doctor.
