Transcatheter aortic valve replacement is a common procedure in Australia.

The surgeon inserts a catheter through a blood vessel in your leg to implant the artificial valve into your heart.

Because it's minimally invasive, it has become a useful alternative to open heart surgery.

However researchers in the US have discovered that since 2018, outcomes from this procedure have been worsening.

And while the change is small, they haven’t been able to find out why it's happening.
