Dr Tom Kaier graduated in Medicine from the Medical University Innsbruck (Austria) and trained in Cardiology in London. He completed his interventional training through training at Barts Heart Centre and St Thomas’ Hospital. During his clinical training, he was both engaged in cardiovascular research and completed a Master of Business Administration.

With the competitive award of a Research Fellowship by the British Heart Foundation in 2015, he was able to complete a PhD in Cardiovascular Medical Research at King’s College London. His research investigated the role of novel biomarkers in ischaemic heart disease on a protein basis. He presented on national and international platforms, was a finalist in several young investigator competitions and won the HyTest Cardiac Marker Award for remarkable scientific work in the field of cardiovascular diseases, as well as the Royal Society of Medicine Research & Innovation Prize. He published extensively in peer-reviewed journals.

After spending a year as Interventional Fellow at Barts Heart Centre, he obtained an NIHR-funded Academic Clinical Lecturer post at King’s College London in 2019. This enabled him to remain research-active whilst expanding his interventional experience as CTO fellow at St Thomas’ Hospital with Dr Antonis Pavlidis. He was subsequently employed as Consultant in Coronary Intervention at St Thomas’ Hospital before moving to Royal Papworth Hospital in 2024.

Dr Kaier is happy to see adult self funding or insured private patients with any cardiac problem but he has a specialist interest in treating patients with chest pain and shortness of breath due to narrowed heart arteries. He specialises in complex stenting procedures from the wrist artery to treat chronic total occlusions of heart arteries.
