No firm statistics exist, but survival rates are decreased in patients with large shunts. The surgical mortality rate in premature infants ranges from 20% to 41%. With the availability of antibiotics to treat endocarditis and low-risk surgery and catheter techniques to obliterate the patent ductus arteriosus (PDA), the mortality rate appears to be quite low except in the extremely premature infant.

It is estimated that left untreated, the mortality rate for patent ductus arteriosus (PDA) is 20% by age 20 years, 42% by age 45 years, and 60% mortality rate by age 60 years. An estimated 0.6% per year undergoes spontaneous closure.
