COS CARDIO is a specialist cardiovascular service led by Consultant Cardiologist Dr Cróchán O’Sullivan, who is based in the Bon Secours Hospital in Cork and the Blackrock Clinic in Dublin.

“My utmost priority is to provide the highest quality and most up-to-date cardiovascular care to all my patients. I aim to achieve this using a holistic approach in a personable and empathetic atmosphere, while taking into consideration each individual patient’s own wishes and hopes for their medical care. My daily clinical practice is characterised by interdisciplinary teamwork and using the most recent evidence based clinical studies to optimise outcomes for my patients.”
