Over
Dr. Costas O’Mahony is a consultant cardiologist at St Bartholomew's Hospital with expertise in the prevention, diagnosis, and treatment of adult heart disease. He graduated with distinction in medicine from Imperial College London in 2001, having also earned a First Class BSc (Hons) in Immunology in 1998. He became a Member of the Royal College of Physicians in 2004 and completed specialist cardiology training at the Heart Hospital and London Chest Hospital in 2014.
Dr. O’Mahony holds an MD(Res) from University College London for his research into sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HCM). He led the development of the internationally adopted HCM Risk-SCD prediction model and remains a leading expert in the management of HCM. His current research focuses on clinical outcomes in cardiomyopathies and pericardial disease. He holds the post of Honorary Associate Professor of Cardiology at University College London.
He is an experienced interventional cardiologist, performing procedures including invasive haemodynamic assessments, right heart catheterisation, cardiac biopsies, alcohol septal ablation, and percutaneous coronary intervention (PCI).
Dr. O’Mahony has lectured internationally, including at the European Society of Cardiology, the British Cardiac Society, the Cardiac Society of Australia and New Zealand and at Tetherdown Primary School in north London.

Myocarditis/Pericarditis
Patients with symptoms of chest pain (angina), shortness of breath, ankle swelling, palpitation, dizzy spells or fainting are evaluated, and investigations are promptly organised to allow accurate diagnosis and treatment.
Individuals without symptoms who are at risk of developing heart problems in the future (e.g. those with diabetes, high blood pressure, high cholesterol, close relatives with heart disease) are assessed and provided with a personalised management plan to reduce risk and improve long-term health. Those with relatives suffering from cardiomyopathy (dilated, hypertrophic, restrictive or arrhythmogenic) are screened to determine if they
are affected.
A clinic consultation is typically followed by investigations to gain a better understanding of the problem. Common first-line, non-invasive investigations include blood tests, ECG (electrocardiogram), Echocardiogram (cardiac ultrasound), 24-hour Holter (ECG monitor), 24-hour blood pressure monitor, CT coronary angiogram and cardiac MRI. If required, invasive procedures (e.g. right and left heart
catheterisation, coronary angiography) are undertaken and treatment with
percutaneous coronary intervention (stents) delivered.
