Biography

Dr Karl Poon is an experienced interventional cardiologist with a special interest in structural heart disease intervention, particularly as a teacher/proctor and high volume operator in TAVI (transcatheter aortic valve implantation).

Dr Poon graduated from the University of Melbourne in 2001 and went on to training at prestigious institutions such as Royal Melbourne Hospital and St Vincent’s Hospital. He undertook an interventional cardiology fellowship at The Prince Charles Hospital and became a senior interventional fellow in 2012 at William Beaumont Hospital in Michigan USA with exposure to MitraClip, TAVI, Watchman devices amongst other complex structural interventions.

In 2015, along with Dr Alex Incani, Dr Poon set up the first private sector TAVI program in QLD and has since established the St Andrew’s Heart Valve Program to be one of the leading programs in the Australasia with best in class efficiency and outcomes, with no procedural mortality after over 300 cases.

Dr Poon is a proctor/teacher for TAVI for Edwards transcatheter heart valve and regularly travels locally and internationally to help teach new TAVI operators and set up new programs. He is an invited panelist at national and international meetings and presents regularly at EuroPCR, LondonValves & ANZET amongst other meetings. He has published over 40 peer reviewed articles, authored 5 book chapters, and practices at The Prince Charles Hospital as a senior cardiologist involved in teaching the next generation of interventional cardiologists.

Dr Poon consults at St Andrew’s Hospital, as well as Northlakes and Greenslopes Private Hospital.

Dr Poon performs invasive procedures at St Andrew’s War Memorial Hospital, as well as Holy Spirit Northside Private Hospital and Greenslopes Private Hospital.

Dr Poon performs TAVI at St Andrew’s War Memorial Hospital, Holy Spirit Northside Private Hospital and Greenslopes Private Hospital.
