About A/Prof Justin Mariani

A/Prof Justin Mariani was trained as a specialist cardiologist in Melbourne at The Alfred Hospital,. He then completed a PhD at Monash University and the Baker Institute. This was followed with an Interventional Heart Failure Fellowship in Toronto, Canada at the University of Toronto. He achieved specialist status as a cardiologist in 2006.

His expertise is in all fields of cardiology, but he has special interest and training in heart failure and cardiomyopathies, surgical implantation and follow-up of devices such as pacemakers and defibrillators (and recognised nationally as a leader in cardiac resynchronisation therapy), and clinical and research interest in haemodynamics (pressure) and cardiac catheterisation.

What is Interventional Heart Failure?

Interventional heart failure is a subspecialty of cardiology. It is a field where cardiologists have had extra training and developed expertise in advanced heart failure and also have interventional (i.e. procedural) skills that can manage heart failure problems. This includes special pacemaker and electrical techniques, cardiac catheterisation techniques, and many other procedures.

Not all patients with heart failure need a procedure, and not all patients needing a pacemaker or angiogram have heart failure. The majority of pacemakers that A/Prof Mariani implants and manages are in patients with electrical issues, and not heart failure. However, he is able to manage both, which is convenient to patients especially for complex technologies, such as cardiac resynchronisation therapy and defibrillators.

About Our Practice

A/Prof Mariani, with his team, aims to provide timely and expert care and medical advice for cardiological problems. For an appointment, or for any queries, please contact his main rooms at (03) 99988300.

For outpatient consultations, A/Prof Mariani sees patients in consulting rooms. In this setting, simple and complex cardiovascular and internal medical issues are evaluated and management plans formed. This setting also allows time for planning for procedures such as coronary angiograms and pacemaker implantation. Some patients, with complicated issues, are followed long term to ensure optimal care. For other patients, the initial consultation may be all that is required to provide a framework for management for the patient and their referring doctor.

New Patients

At your first consultation with A/Prof Mariani, we will ask you to complete a new patient registration form and medical questionnaire.

A/Prof Mariani sees patients in all settings, and manages inpatients and outpatients at one public hospital (The Alfred, Melbourne) and one private hospital (St Vincent’s Private) where he has admitting, coronary care management and procedural rights.

We triage our referrals. Everyone wants to be seen quickly - we know this. However, management of cardiac conditions can be time critical. Further, some issues can be sorted prior to the initial consultation, which may mean that we recommend specific tests prior to the consultation.

We know that some referrals are detailed, and others are not. Where the referral might say "Thanks for seeing Ms X for a cardiovascular review", this does not help with triage. If you feel your problem is more significant, please send the information through to us on our contact form or email it to admin@jmcardiology.com.au or call the rooms on (03) 99988300. Also, please ask your referring doctor to contact us.


Being a consultant cardiologist means A/Prof Mariani sees and manages patients presenting with conditions of the heart and blood vessels. These can be established conditions (where we know the problem and are treating it and any further issues) or diagnostic problems which require further evaluation along with management.

Often cardiac conditions may present urgently - in this setting, A/Prof Mariani works in hospitals, including coronary care units, to manage these conditions along with other hospital staff. Sometimes these problems require invasive procedures, many of which A/Prof Mariani actively performs. Where he does not perform these procedures, for example open heart surgery or AF ablations, A/Prof Mariani works with other specialists such as cardiac surgeons and electrophysiologists to ensure the best outcome for patients and their families.

Cardiovascular disease is the biggest killer in Australia. It also causes the most impact to the population and society it terms of cost and quality of life. We also know that patient will do better if they know about their conditions, and understand the causes that contribute and the management - especially where they can make a difference.
