Biography

Dr Ryan Markham is an Interventional Cardiologist who specialises in the management of coronary and structural heart disease. He’s located in Queensland consulting at the St Andrew’s Specialist Centre, Mater Private Hospital in South Brisbane and Redlands, Greenslopes Private Hospital and Sunnybank Private Hospital.

After completing his Bachelor of Medicine, Bachelor of Surgery at the University of New South Wales he completed further training at The Prince Charles Hospital, Brisbane in advanced cardiology and interventional cardiology. During this time, Dr Markham also completed a Master of Philosophy focusing on mitral valve annular geometry before and after transcatheter mitral valve therapy at the University of Queensland.

Following this, he travelled to the United States to complete further fellowship training in interventional cardiology at Stanford University and was involved in a number of research and clinical trials. He was awarded a position to be involved in the development of medical devices for patients with critical cardiovascular disease with the Stanford Byers Centre for Biodesign.

Dr Markham continues to contribute his knowledge and experience in a number of research publications, presenting regularly at international meetings and is a lecturer at the University of Queensland.
