Interventional Cardiologist
Chris is a cardiologist who has trained in all aspects of cardiology with a sub-specialist in Interventional cardiology. He completed his training in Melbourne, Australia and furthermore completed a three-year post-graduate fellowship in Oxford, UK. He also specialises in complex percutaneous coronary intervention (PCI).
Chris has written many international publications and is completing his research doctorate. He has introduced the use of the latest techniques including Radial Artery Access angiography and stenting, intracoronary imaging with OCT and IVUS as well the Pressure Wire (FFR) technique to assess the individual coronary stenosis for ischaemia. These techniques have been deemed as revolutionary in the cardiac interventional diagnosis scheme.
The following services are provided by Chris:
- Assessment and management of the full spectrum of cardiac conditions
- Non-invasive investigations
- Cardiac catheterisation, coronary angiography, and a specialist in complex PCI
- Pioneer of Radial Artery Access procedures for angiograms and PCI in Victoria (helped introduce this technique to Epworth Eastern, using the artery in the wrist compared to the groin. Much lower risk of vascular complications, and much improved patient comfort compared to femoral artery access).
- Pioneer of Drug Eluting Balloon Angioplasty (Performed the first drug eluting balloon angioplasty in an Epworth Hospital in Melbourne)
- Pioneer of the Pressure Wire (FFR/Fractional Flow Reserve) to distinguish stenoses that need PCI and those that can be safely managed conservatively. (Performed the first pressure wire procedure in Epworth Eastern)
- Emergency PCI for treatment of acute myocardial infarction
Chris is multilingual and fluent in languages other than English including: Mandarin, Cantonese, Fujian, Malay/Bahasa
Qualifications:
MBBS FRACP- University of Melbourne 2000
Post Graduate Fellowship: 2008 – 2010 John Radcliffe Hospital, Oxford UK
Public Hospital Appointment: Staff Specialist at The Northern Hospital
Private Hospitals: Various hospitals including On-Call Cardiologist and Weekly Cath Lab Sessions at the Epworth Eastern Hospital, Box Hill.

Associate Professor Han Lim
MBBS, PhD, FRACP, FCSANZ, FHRS
Consultant Cardiologist and Electrophysiologist
Han obtained his Bachelor of Medicine and Bachelor of Surgery (MBBS) degree from the University of Melbourne and completed his Cardiology training at the Austin Hospital, before undertaking subspecialty training in the area of cardiac electrophysiology and device implantations.
He is a recipient of the NHMRC (National Health and Medical Research Council) Medical Postgraduate Scholarship for his PhD in the area of stroke prevention in atrial fibrillation (AF). Han is the first Australian cardiologist to be awarded the Parmley Prize from the American College of Cardiology in 2012.
He is also a Finalist in the American Heart Association Samuel Levine Young Investigator Award in 2014 and a recipient of the NHMRC Neil Hamilton Fairley Early Career Fellowship.
For his overseas advanced cardiac electrophysiology fellowship, Han trained with Professor Michel Haissaguerre in Bordeaux, France, who pioneered the technique of catheter ablation for AF. Han has extensive experience in the area of catheter ablation for complex arrhythmias, including the latest ablation techniques for AF, supraventricular tachycardia and ventricular tachycardia, as well as pacemaker and implantable cardioverter-defibrillator implantations.
He has authored and co-authored 6 book chapters and >100 peer-reviewed journal publications in the area of Cardiac Electrophysiology and Cardiology in major international cardiology journals such as the Journal of American College of Cardiology, Circulation Arrhythmia and Electrophysiology, Circulation, Journal of American Heart Association, Europace and Heart Rhythm. He is a regular presenter at national and international Cardiology conferences.
Han holds public appointments at Austin Hospital and Northern Hospital. He leads the research program at Austin Health in the field of cardiac electrophysiology, and is responsible for supervising and training electrophysiology fellows at Austin Health. Han currently serves as the Australian representative for the Asia Pacific Heart Rhythm Society.
He is an Associate Professor at the University of Melbourne. His research interests are in the area of heart rhythm disorders, particularly atrial fibrillation and stroke, and sudden cardiac death.
