Flow based indices of stenosis severity

Dr Sharp qualified from Edinburgh Medical School in 1998. He was appointed as a Consultant Cardiologist at the Royal Devon and Exeter Hospital in 2011, before moving to the University Hospital of Wales, in Cardiff, UK in the summer of 2019, where he is now Honorary Professor of Cardiology. He conducted his early training at the Royal Infirmary of Edinburgh, before moving to London for his senior clinical training. He completed the Milan-Imperial Interventional Cardiology Fellowship programme, having spent a year in San Raffaele and Columbus Hospitals, Milan, Italy, under the tutelage of Professor Antonio Colombo. He also spent three years training in interventional cardiology at St Mary’s Hospital and The Hammersmith Hospital (Imperial College Hospitals) in London. Prof Sharp was awarded an MD postgraduate research degree from the University of Edinburgh for his work on the hypertensive heart and leads a large research programme in Wales. He has an international reputation for leading the development of device-based treatments for hypertension (in particular that of renal denervation) and pulmonary embolism, as well as the advancement of intracoronary imaging and physiology.

Dr. Bruce Samuels is an interventional cardiologist on staff at Cedars-Sinai Medical Center (CSMC) in Los Angeles, California. Dr. Samuels completed his medical studies at Albert Einstein College of Medicine in New York before returning to Southern California to complete his residency and chief residency in Internal Medicine at Harbor-UCLA Medical Center. At CSMC, he trained in both general and interventional cardiology before joining the medical staff there. In addition to his clinical practice in coronary intervention, Dr. Samuels has actively participated in numerous interventional trials including IVUS guided therapy, coronary physiology and microvascular disease. He is also working closely with the Barbra Streisand Women’s Heart Center based at CSMC, working as an interventionalist in the active coronary reactivity research there. As co-chair of a 30-day readmissions task force, he has helped to shape policy for CSMC in its efforts to improve quality delivery of care. He has frequently been invited as faculty to many scientific meetings and is a sought after speaker for numerous peer educational platforms. Dr. Samuels is a fellow of the American College of Cardiology and is Board Certified in Internal Medicine, Cardiovascular Diseases, and Interventional Cardiology. He is married with three sons; his outside interests include contemporary art and long distance running.

Dr Justin Davies is founder and CEO of Wondr Medical, inventor of iFR, and clinical academic and consultant interventional cardiologist at the National Heart and Lung Institute, Imperial College London.

Dr Ricardo Petraco is a NIHR Lecturer in interventional Cardiology at Imperial College London, performing his clinical work at Hammersmith Hospital. He has been working with coronary physiology at Imperial since 2010 on the development of the novel instantaneous wave-Free Ratio (iFR). Dr Petraco’s work with iFR has led to the proposition of the Hybrid iFR-FFR approach and has established iFR’s close relationship with coronary flow reserve (CFR). His interests in computer programming has led to the development of a software for automated analysis of coronary haemodynamics signals which is been used by many leading centres in the world. He has also pioneered the algorithm for iFR calculation without the need for an ECG signal, an approach which is now implemented in clinical consoles. He has secured several research grants and published extensively in the field of coronary physiology. His current research interests are on the development of methodologies to assess stenosis severity in situations of haemodynamic instability and on the understanding of how medical therapies modulate coronary resistance and flow. Clinically, his interests also include the use of intravascular imaging modalities to optimise PCI and has been engaged in IVUS training for cathlab staff and cardiology trainees.
