Structural heart research
The Structural Heart Program commenced in 1995, when the team were pioneers in Australia, being the first to provide Transcatheter Aortic Valve Implantation (TAVI) in Victoria in 2008. TAVIs are provided to high risk patients with severe aortic stenosis. This program continues to be one of the largest in Australia.
Associate Professor Tony Walton leads a highly experienced and enthusiastic team of researchers including experienced structural heart interventional cardiologists and researchers, a structural heart fellow, doctoral (PhD) researchers and research nurses.
The Structural Heart Program research covers international commercially sponsored trials and site Investigator driven research. The research program has consistently made a significant academic contribution with international journal publications, conferences presentations and involvement in international clinical trials.
Research focus
Our areas of research focus are in the assessment of new devices for the treatment of aortic and mitral valve conditions as TAVI, MitraClip and TMVR procedures, closure devices for reducing the risk of stroke such as LAA and PFO, high frequency ultrasound renal denervation studies for hypertension and assessment of new devices for the treatment of heart failure.
The Alfred TAVI program was the largest Australian site to recruit participants into the Medtronic International TAVI Clinical Trials CoreValve ANZ high risk trial, Evolut R Forward Trial and the Evolut R TAVI vs SAVR Low Risk Trial, and was a high enroller site for the Edwards Solace trial, and the Abbott Vascular Portico 1 and Portico IDE trials.
The Alfred is the only Australian site in the Medtronic SPYRAL HTN ON and OFF Meds trials for interventional treatment of hypertension with renal denervation.
We are also one of few Australian sites to be involved in the first in human trials for the transcatheter replacement of the mitral valve.
If you are interested in becoming involved with one of our clinical trials, please contact one of our helpful research team members for further information.
