Transcatheter Pulmonary Valve Replacement (TPVR)
TPVR, also known as transcatheter pulmonary valve replacement is a way of replacing the pulmonary valve in the heart without the need for conventional open-heart surgery.
A number of patients with congenital heart disease have problems with their pulmonary valve, either since birth, or after cardiac surgery. For many patients, a valve replacement may be recommended. Until the last decade replacing a faulty pulmonary valve could only be done with open heart surgery. Because all surgically implanted valves have a limited life-span, patients faced many surgeries over the course of their life to replace the pulmonary valve. The percutaneous, non-surgical option to replace the pulmonary valve has revolutionized the care of these patients.

What?
A number of patients with congenital heart disease have problems with their pulmonary valve, either since birth, or after cardiac surgery. For many patients, a valve replacement may be recommended.
How?
The goals of transcatheter pulmonary valve replacement is to replace the pulmonary valve non-surgically and decrease the number of heart surgeries a patient will need over their life-time
Whom?
Patients who may benefit from a transcatheter pulmonary valve include those with:
- Tetralogy of Fallot who have had prior surgery but now have a leaky or narrowed pulmonary valve, especially if they have undergone a prior surgical replacement.
- Patients with other underlying diagnoses who also have a surgically implanted pulmonary valve (such as a homograft or a bioprosthetic valve) that is no longer working well; including patients with truncus arteriosus, patients with aortic valve disease who have had a Ross procedure, and some patients with pulmonary stenosis or atresia.
