The prognosis is poor with progressive aneurysmal dilatation or rupture unless early surgical repair is performed. [21]

Actuarial survival rate for patients with congenital SVA is 95% at 20 years, since most SVAs do not rupture prior to age 20 years.

Unruptured SVA has been observed in serial monitoring up to several years after initial diagnosis, but most unruptured SVAs have been found to progress and rupture.

Untreated SVAs may rupture, and patients with ruptured SVAs die of heart failure (with left-to-right shunting) or endocarditis within 1 year after onset of symptoms of ruptured SVA.

In a series of 86 patients who underwent SVA repair, ruptures occurred in 34%. Six (7%) died perioperatively; the actuarial 10-year survival rate was 63%. These patients often required concomitant surgical repair of associated ventricular septal defect, atrial septal defect, and the aortic valve. [7]
