Dr Indraratna oversees the cardiac CT program at Prince of Wales Hospital in Randwick, where he reports cardiac CT scans for hospitalised patients, and trains junior doctors in image interpretation. He is also a tutor at the certification course run by the Australian Institute for Cardiac CT for cardiologists and radiologists. Dr. Indraratna possesses expertise in the utilisation of cardiac CT in coronary artery disease, complex congenital heart disease, structural and valvular heart disease. This stems primarily from a cardiac CT fellowship at St. Paul’s Hospital in Vancouver, Canada—an institution recognized globally for its excellence in cardiac CT imaging.
