Abstract
Sinus of Valsalva aneurysm (SVA) is rare, and aneurysm of the left sinus of Valsalva
is extremely rare cardiovascular disease. Clinical presentation can vary from mostly
asymptomatic to catastrophic life-threatening emergency. We report four extremely
rare cases of SVA with different manifestations of which one case involved left aortic
sinus with large unruptured aneurysm causing severe mitral regurgitation (MR) and
severe aortic regurgitation (AR). The second case aneurysm was from right sinus presented
with trifascicular block with intermittent complete heart block (CHB). Third was a
diagnosed case of unruptured right SVA and while awaiting for surgery he had sudden
cardiac death (SCD) at home. Therefore, SVA can present from asymptomatic to life-threatening
condition, such as SCD. To the best of our knowledge, there are individual case reports
in literature, and this is the first case series of unruptured SVA in literature highlighting
the rarity of this disease.
