Biography


Professor Michael Vallely is a leading cardiothoracic surgeon with clinical appointments at Royal Prince Alfred, Concord, Strathfield Private, Macquarie University and Southern Highlands Private Hospitals (Bowral). He also provides consulting services at St Vincent’s specialist suites next to the hospital in East Lismore.

Professor Vallely has a special interest in elderly and high-risk patients with multiple medical issues and minimally invasive heart and lung surgery. 

Professor Vallely and Professor Michael Wilson established Australia’s fully-integrated robotic cardio-thoracic surgery program covering coronary grafts, mitral valves and lungs. Their interest in minimally invasive cardiac surgery culminated in Macquarie University Hospital successfully completing its first Off-Pump Coronary Artery Bypass Graft (OPCABG) in 2017, using the da Vinci Xi Surgical System.

Professor Vallely holds Clinical Professorships at The University of Sydney and Macquarie University, is a member of the board for The Baird Institute for Applied Heart, and Lung Surgical Research and of the Royal Australasian College of Surgeons Cardiothoracic Board. He is the leader of the Baird Institute’s Innovative Heart Surgery Research Group and supervises a clinical and basic research team of Honours, Masters and Doctoral students and is a member of the board of the Royal Prince Alfred Institute for Academic Surgery.

Professor Vallely graduated from The University of Sydney in 1995, completed a PhD from the same institution in 2005 and was awarded an FRACS (CTh) in 2007. He was the Professorial Fellow at The Royal Brompton Hospital, London, in 2007-08 and was appointed as a cardiothoracic surgeon at Royal Prince Alfred Hospital, Sydney in 2008.

Professor Vallely has clinical and academic interests in minimising the invasiveness of cardiothoracic surgery and is a world authority on total arterial, anaortic, off-pump coronary artery bypass surgery. He also has interests transcatheter (TAVI and Mitra-Clip) cardiac surgery, thoracic aortic surgery, geriatric cardiac surgery and hybrid procedures including the use of ECMO. 

Professor Vallely performs more than 250 electrophysiological (pacemakers, defibrillators and CRT) implants per year. He has presented extensively at national and international conferences and authored or co-authored more than 80 scientific publications in peer-reviewed journals.
