Detecting ischaemia using iFR and FFR in clinical practice

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.
