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.

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.
