Harmony™ TPV system

Made for this

Treating congenital heart disease patients takes focus. When you are in the moment, you need to make sure you have the right valve. The Harmony transcatheter pulmonary valve (TPV) system is made for this moment.

Evidence and innovation

The only one.

Harmony TPV is the only transcatheter pulmonary valve designed specifically for the RVOT with demonstrated consistent two-year outcomes.

Data is provided from the Harmony TPV Clinical Study through two years.
Harmony TPV risks may include, but are not limited to, non-sustained ventricular tachycardia, premature ventricular contraction, minor paravalvular leak, stenosis, and migration of the TPV.


Made for patients like Hunter.

Hunter, born with tetralogy of Fallot, is living his life to the fullest thanks to his transcatheter pulmonary valve procedure in 2021.

Made for advancing TPV therapy.

The Harmony TPV was intentionally designed for the native RVOT. It conforms to the anatomy and has an integrated valve and frame to allow a one-step delivery.


The Harmony transcatheter pulmonary valve (TPV) system is indicated for use in the management of pediatric and adult patients with severe pulmonary regurgitation (i.e., severe pulmonary regurgitation as determined by echocardiography and/or pulmonary regurgitant fraction ≥ 30% as determined by cardiac magnetic resonance imaging) who have a native or surgically repaired right ventricular outflow tract and are clinically indicated for surgical pulmonary valve replacement.

Valve and system overview

Made for the native RVOT.

Harmony TPV is the first FDA-approved transcatheter valve system specifically designed to treat severe pulmonary regurgitation in patients with a native or surgically repaired right ventricular outflow tract (RVOT) — offering your patients a minimally invasive treatment option.

Designed specially for the native RVOT in three ways:

Fully sheathed delivery system

Fully sheathed delivery system is highly trackable through the vasculature.1

Self-expanding nitinol frame

Harmony TPV is constructed of a self-expanding nitinol frame made up of individual wire struts, designed to conform to the native RVOT anatomy.

Pericardial leaflets

Porcine pericardial leaflets provide excellent kinematics across the full range of pressures of the right heart.2,3

Valve features

  • The valve and frame are integrated to provide a one-step delivery process, facilitating predictable device deployment in the intended position4
  • Porcine pericardial tissue valve 
  • Self-expanding nitinol frame
  • Polyester cloth covering
  • Multiple valve sizes with different inflow diameters, outflow diameters, and lengths to fit a range of patient anatomies

Delivery catheter features

  • Coil loading system facilitates simple loading of the valve
  • Loading funnel to compress valve prior to sheathing
  • Retractable sheath
  • Ergonomic handle facilitates unsheathing and release of valve for final deployment
