Stephen J. Duffy is a cardiologist based in Wellington Road, Melbourne, VIC 3800, Australia. He looks after people who have heart and blood vessel problems, from day-to-day symptoms to urgent, life-threatening situations.
In many cases, his work involves helping with blocked or narrowed heart arteries. That can include conditions like coronary heart disease, atherosclerosis, stable angina and unstable angina. He also supports patients who have had or are at risk of a heart attack. At times, this care happens in emergency settings, where quick decisions really matter.
His clinic and hospital care can include procedures such as percutaneous coronary intervention (PCI) and angioplasty. He may also be involved in thrombectomy for clot-related problems, and atherectomy when plaque needs special treatment. For some people, care can include follow-up planning after procedures, especially when there are ongoing heart risks.
Stephen also works with valve and structural heart issues. This includes aortic valve stenosis, mitral valve regurgitation, and situations where valve replacement is needed. Procedures listed in his practice include transcatheter aortic valve replacement (TAVR) and aortic valve replacement. At times, patients also need treatment after more complex heart history, including coronary artery bypass graft (CABG) and heart bypass surgery.
Some referrals also involve heart weakness and sudden, serious events. This can include cardiomyopathy, heart failure, and cardiac arrest. He may also be involved in cases with cardiogenic shock, where the heart isn’t pumping enough and urgent treatment is required. Beyond the heart, he also looks at related issues such as peripheral artery disease and stroke, because these conditions often travel with heart disease.
His training is in cardiology, with a focus on safe, patient-centred care across both routine and emergency heart treatments. He stays grounded in practical medicine, and aims to explain what’s going on in plain language—especially when things are stressful or fast-moving.
