Abstract

OBJECTIVE:

Women who underwent an atrial switch procedure (Senning or Mustard) for repair of d-transposition of the great arteries (d-TGA) are now of reproductive age. We sought to assess their ability for a successful pregnancy.

STUDY DESIGN:

Clinical data were reviewed for all women of reproductive age who carried a diagnosis of d-TGA and atrial switch procedure who were observed at 2 tertiary care centers over 10 years.

RESULTS:

Among 25 women who were identified, there were 21 pregnancies that resulted in 14 live births. The preterm birth rate was 50%. Pregnancy complications occurred in 5 women. There were no deaths. Serial echocardiographic data demonstrated a fall in right ventricular function during pregnancy, with some improvement postpartum. Intracardiac baffle obstruction that required postpartum stenting occurred in 36% of the completed pregnancies.

CONCLUSION:

Women who have undergone an atrial switch procedure for d-TGA have high rates of pregnancy and cardiac complications and should be counseled accordingly.
