Dr Antonis Pantazis

Consultant cardiologist
Specialises in cardiomyopathies, including arrhythmogenic, dilated and hypertrophic cardiomyopathy.

Dr Antonis Pantazis is a consultant cardiologist at Royal Brompton and Harefield hospitals.

Prior to this, he was a consultant cardiologist at the Heart Hospital, University College London Hospitals NHS Foundation Trust (UCLH), from 2007, and a consultant cardiologist at Barts Heart Centre at St Batholomew’s Hospital, London, from 2015. 

Whilst at UCLH, he was the leading cardiologist in its neuromuscular complex care centre (NMCCC) in the National Hospital for Neurology and Neurosurgery. 

During this time, he developed dedicated clinics for arrhythmogenic cardiomyopathy (ARVC), cardiac and neuromuscular sarcoidosis. He was also the leading cardiologist for the surgical and interventional programmes for the management of left-ventricular outflow tract obstruction (LVOTO) in hypertrophic cardiomyopathy.

Clinical expertise

Dr Antonis Pantazis is a leading expert in cardiomyopathies and has a special interest in:

  • arrhythmogenic cardiomyopathy 
  • dilated cardiomyopathy 
  • hypertrophic cardiomyopathy. 

He consults with patients with cardiomyopathies, from diagnosis to invasive management and medical treatment. He has extensive experience in the management of left ventricular outflow tract obstruction, and guides procedures including alcohol septal ablation and surgical myectomy. 

His practice includes diagnostic investigation of inherited conditions in families, through family screening with clinical and genetic tests. At Royal Brompton and Harefield hospitals, he was instrumental in the development of its inherited cardiovascular conditions (ICC) service, its ARVC clinic and its programme for the management of LVOTO in hypertrophic cardiomyopathy. 

He has a special interest in echocardiography to investigate cardiomyopathy, valvular heart disease and ischaemic heart disease. He also leads the echocardiography department at North Middlesex University Hospital.

Research interests

Dr Pantazis research interests include:

  • advanced cardiac imaging in relation to cardiomyopathies, intracardiac device implantation and valve diseases
  • cardiac phenotype in Friedreich’s ataxia
  • cardiac phenotype in neuromuscular diseases
  • phenotype / genotype in left-ventricular non-compaction cardiomyopathy and ARVC.

He is the chairman-elect of the European Society of Cardiology working group on pericardial and myocardial diseases.


Dr Pantazis has published research related to cardiomyopathy in a number of peer-reviewed journals and has contributed to cardiac guidelines for Ataxia UK on Friedreich’s ataxia.


Dr Pantazis regularly speaks at national and international meetings and conferences to share his knowledge. 

He has previously held the position of honorary senior lecturer at University College London (UCL) where he supervised junior doctors and taught medical students. During his time at UCL, he was also the academic lead for echocardiography at its Institute for Cardiovascular Science and the London Deanery lead for specialist registrar (SpR) echocardiography training.
