Pregnancy After Transcatheter Pulmonary Valve Implantation.

Transcatheter pulmonary valve implantation (TPVI) is a relatively new method of treating patients with significant pulmonary regurgitation or pulmonary stenosis, or both, after reconstruction of the right ventricular outflow tract. It is an attractive alternative to conduit replacement in this group of patients, who are typically young and active. This report includes 4 young women who after successful TPVI became pregnant and gave birth. Transthoracic echocardiography, cardiopulmonary exercise testing, and cardiac magnetic resonance imaging were performed in all patients. The results suggest that pregnancy and delivery after successful TPVI is safe when the appropriate precautions have been taken.
