Dr Tan Sian-Tsung

Clinical Interest:

Investigation and Management of Coronary Artery Disease, including Acute Myocardial Infarction (Heart Attacks) and Chronic Angina


Dr Tan Sian-Tsung is a Specialist in Cardiology. He received his MBBS from Guy’s, King’s and St Thomas’ School of Medicine in the United Kingdom (UK) in 2005, and was awarded a Merit for his pre-clinical work. He underwent advanced specialist training in Cardiology in the East of England Deanery (East Anglia rotation), which culminated in the completion of his subspeciality training in Interventional Cardiology in the region’s tertiary centres (Royal Papworth Hospital and Norfolk and Norwich University Hospital).

Prior to joining Raffles Hospital, Dr Tan served as Senior Interventional Fellow in complex interventional cardiology (Chronic Total Occlusion (CTO) treatment and Left Ventricular (LV) support) at the Royal Brompton and Harefield Hospitals over a 22-month period, under the supervision of Dr Jonathan Hill. Royal Brompton and Harefield Hospitals are the largest heart and lung centres in the UK, and one of the largest in Europe. During his fellowship, he also worked as an honorary cardiology consultant at Northwick Park Hospital overseeing a busy cardiology unit.

Dr Tan was an integral member of the biweekly revascularisation multi-disciplinary team, and actively participated in the cardiogenic shock programme, enhancing his understanding of the rationale underpinning complex decisions for triaging the treatment of both coronary and valvular disease. Dr Tan has performed over 1,000 percutaneous coronary intervention (PCI) cases, including more than 250 complex procedures and over 125 primary angioplasties.

Dr Tan has strong interests in research and clinical innovation. He was a sub-investigator in the ongoing Reducer-1 trial at Royal Brompton Hospital and has presented in multiple international cardiology conferences. He has published over 18 peer-reviewed research studies in journals such as The New England Journal of Medicine and Nature.

Dr Tan possesses clinical expertise in all aspects of general and interventional cardiology, which includes cardiovascular risk assessment, interventional cardiology, including coronary physiology assessment, CTO angioplasty, use of LV assist devices (Impella CP) and insertion of coronary sinus reducers. He has special interests in the investigation and management of coronary artery disease, including acute myocardial infarction (heart attacks) and patients with chronic angina.

Dr Tan advocates the use of latest technologies and techniques to ensure all his treatments are evidence-based and optimised. He believes in holistic care and always adopts a patient-first approach when it comes to decision making. He ensures that all management options are in the patients’ best interests, and takes into account their individual circumstances to give them the best possible quality of life.
