About Dr John Ramzy

Portrait of Dr John Ramzy

Dr John Ramzy is a general and interventional cardiologist, subspecialising in coronary and structural intervention, with an interest in adult congenital heart disease.

After graduating from the University of Melbourne, he trained in five of Melbourne’s cardiology units: St Vincent’s Hospital, University Hospital Geelong, Box Hill Hospital, The Alfred and The Royal Melbourne Hospital. He then completed a two-year interventional cardiology fellowship at Monash Heart, followed by an advanced fellowship in structural and adult congenital heart intervention at Toronto General Hospital in Canada.

He has a particular interest in using intracoronary imaging and coronary physiology so that procedures are planned and performed with precision. He also performs structural heart procedures including TAVI, PFO and ASD closure and left atrial appendage occlusion, working with your GP and, where relevant, your neurologist.

Dr Ramzy speaks English and Arabic.
