Transcatheter-placed pulmonary valve

Case contributed by Dr Jayanth Keshavamurthy


Tetralogy of Fallot. Surgically-corrected VSD and bioprosthetic pulmonary valve. Presented with shortness of breath. Underwent a second pulmonary valve replacement.

Patient Data

Age: 20 years
Gender: Male


Original Carpentier-Edwards valve. Sternotomy wires of two kinds.

Ventricular septal defect (VSD) repair first.

Bioprosthetic valve in a right ventricular outflow tract (RVOT) conduit.


Postoperative image showing the percutaneously placed pulmonary valve on top of the older valve.

Case Discussion

Conclusions of cardiac MRI prior to transcatheter pulmonary valve replacement:
1. Patient born with tetralogy of Fallot. Surgically corrected VSD and prosthetic pulmonary valve are seen. 5-vessel aortic arch with a retroesophageal course of the right subclavian artery arising from the descending thoracic aorta.

2. RVOT measures 38 mm in the maximal dimension. The main pulmonary artery measures 24 mm in the maximum dimension. Right and left pulmonary arteries measure 21 and 24 mm in diameter.

3. Right ventricle: Right ventricular dilatation, right ventricular hypertrophy, RV end diastolic volume index at least 135 mL. RV ejection fraction 53%.

3. Valvular function: Severe pulmonary regurgitation of the prosthetic pulmonary valve (57%).

4. Delayed enhancement: none seen.

Therefore a transcatheter valve has been placed due to evidence of failure of the original valve.
