A new cardiologist-led campaign is pushing for more Australians with aortic stenosis to access a minimally invasive aortic valve replacement procedure and avoid open-heart surgery.

But leading interventional cardiologists have cautioned against a one-size-fits-all approach amid concerns over the durability of the valves in the absence of long-term data.

Launched last week, the Hope for Hearts campaign aims to raise awareness about the heart condition and calls for changes to national guidelines to broaden access to transcatheter aortic valve replacement (TAVR).

The campaign is funded by TAVR manufacturer Edwards Lifesciences, which has asked the Medical Services Advisory Committee to expand the MBS item for TAVR to include patients at intermediate risk of perioperative mortality with surgical aortic valve replacement.
