Lexapro, did it cause my baby's heart defect?

Hello, I have been taking Lexapro for over 4 years now for depression , it works great!
I've seen alot of things on tv about antidepressants being linked to heart defects in babys.
My son was born 2 years ago with Hypoplastic Left Heart Syndrome (www.HLHS.com) and I wanted to know if Lexapro has been related to any heart defects.

Lexapro might be the cause of the heart defects.

Pregnancy Implications for Lexapro - Teratogenic effects have been reported in animal studies. Nonteratogenic effects including respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypo- or hypertonia, hyper-reflexia, jitteriness, irritability, constant crying, and tremor have been reported in the neonate immediately following delivery after exposure late in the third trimester. Exposure to SSRIs late in pregnancy has also been associated with persistent pulmonary hypertension of the newborn (PPHN). Adverse effects may be due to toxic effects of SSRI or drug discontinuation. In some cases, effects may present clinically as serotonin syndrome. There are no adequate and well-controlled studies in pregnant women. Use during pregnancy only if the potential benefit to the mother outweighs the possible risk to the fetus. If treatment during pregnancy is required, consider tapering therapy during the third trimester.
