Measuring iFR in Aortic Stenotic, Atrial fibrillation, and Chronic Heart Failure

Dr Justin Davies is a honorary

interventional cardiologist at Hammersmith Hospital, Imperial College NHS Trust, London. After training at Imperial College, he won a prestigious BHF research fellowship to study arterial haemodynamics. Since then he has continued to
work on the development of mathematical algorithms to aid understanding of large artery physiology and to develop new tools to assess arterial disease. The holder of several patents,
he has published widely in the field of hypertension, coronary and large artery physiology and is the winner of many national and international awards. He has several international collaborations, and is the developer of iFR and the co-principal investigator of the ADVISE studies, the DEFINE-FLAIR, ORBITA and DEFINE-PCI studies. Justin also has an interest in renal denervation, and has lead the first-in-man studies to evaluate the safety of this technique to patients with chronic systolic heart failure (REACH studies).

Dr Sukhjinder Nijjer is a Consultant Cardiologist and Honorary Senior Clinical Lecturer at Imperial College London. He is the President of Cardiology at the Royal Society of Medicine and is the Communication Lead for the British Cardiovascular Intervention Society. He works at the Hammersmith Hospital as an Interventional Cardiologist and is an expert in Coronary Physiology. His PhD research focused on the development of instantaneous wave-free ratio (iFR) pullback and co-registration. He has published over 100 original academic papers and has involved in the DEFINE-FLAIR, SYNTAX-II and ORBITA-1 and ORBITA-2 research studies. Read more Show less

Dr Ricardo Petraco is a NIHR Lecturer in interventional Cardiology at 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.

Prof Andrew Sharp qualified from Edinburgh Medical School in 1998 and is Professor of Cardiology at the University Hospital of Wales and Cardiff University in the U.K. He conducted his early training at the Royal Infirmary of Edinburgh, before moving to London for his senior clinical training. He completed the prestigious 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 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 his research interests include intracoronary imaging and physiology. as well as the use of device-based treatments for hypertension and pulmonary embolism.
