Breakout session: Common pitfalls of FFR and iFR assessment - Dr Ricardo Petraco

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 Nieves Gonzalo is Consultant Interventional Cardiologist at the Interventional Cardiology Department at Clinico San Carlos University Hospital in Madrid. She obtained her Specialist Certification in Cardiology after training at Clinico San Carlos University Hospital in Madrid. Subsequently, she underwent a research fellowship at Thoraxcenter, Erasmus University Rotterdam (The Netherlands) under the supervision of Professor Patrick Serruys, focused mainly in intracoronary imaging and bioabsorbable stents. In 2010 she obtained her PhD with the thesis “Optical coherence tomography for the assessment of coronary atherosclerosis and vessel response after stent implantation”. Her track record includes over 170 articles indexed in PubMed, as well as book chapters in Interventional Cardiology textbooks. Recent research projects as principal investigator includes a study about the assessment of neoatherosclerosis and its clinical impact in patients with restenosis (RIBS IV and V OCT substudy) and research regarding vessel injury and healing evaluation with different stent platforms evaluated with OCT (VISTA study). Dr Gonzalo is a dedicated educationalist with involvement in many areas of complex PCI, serving currently as Deputy Editor for Eurointervention and Committee Member of EuroPCR.

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.
