Overview

Mapping and ablation of post-infarct related ventricular tachycardia (VT) remains a challenge. Conventional activation and entrainment methods are limited by poorly tolerated VT’s, multiple VT’s, complex circuits and the deleterious effects of mapping in VT on cardiac, renal and cerebral function. The resultant effect is poor long term outcomes.

 

Classical substrate mapping techniques predominantly involve mapping ventricular scar substrate in intrinsic rhythm, however, VT circuits may be dynamic, and substrate characteristics may not be static or prevalent in intrinsic rhythm. Emerging functional substrate assessment methods of VT ablation may improve outcomes from VT ablation and may be safer by reducing the need for the patient to be in VT for prolonged periods of time.

 

This webinar discusses presently available techniques.

Andreu  Porta-Sánchez

Andreu Porta-Sánchez

Personal History

Dr Andreu Porta-Sanchez is a Postdoctoral Scientist and a Staff Cardiologist based in Madrid, Spain.

He is a specialist in the field of complex arrhythmias including hereditary and genetic arrhythmias, ventricular tachycardia, atrial fibrillation, hisian pacing and cardiac resynchronization. He also specialises in ablation procedures with catheters.2

 

Academic History

Dr Porta-Sánchez graduated from the Universitat de Barcelona in 2007 and started his residency in cardiology at Hospital Universitari Vall d’Hebron in Barcelona. After completing his residency, he received a post-graduate training grant from La Caixa Banking Foundation and pursued further clinical and research training in arrhythmia at the University of Toronto, Canada, from 2014 until 2017.1

He completed his Masters in Methodology of Clinical Research at Universitat Autònoma de Barcelona in 2017. In 2018, he was awarded his first competitive grant as a PI from Sociedad Española de Cardiología for a clinical project in electroanatomical mapping. In 2019, Dr Porta-Sánchez completed his PhD atthe Universitat de Barcelona with his thesis entitled New Techniques Treatment of Ventricular Tachycardia, which received an excellent cum laude rating.2

 

Career Overview

Dr Porta-Sánchez combines his clinical work as an Adjunct Doctor of the Arrhythmia Unit at Hospital Universitario Quirónsalud Madrid and Ruber Juan Bravo, where he specialises in complex arrhythmia ablation procedures with catheters and conducts his research at the Molecular Cardiology Laboratory of the National Center for Cardiovascular Research.1, 2

Dr Porta-Sánchez is also an Associate Professor of Medicine at the European University and has received the European Certification of Specialist in Electrophysiology. He is the author of numerous publications in scientific journals and his research career has been recognized with honourable mentions at two international conferences.

He is an active member of EHRA and is the co-chair of the Selection Committee and the EHRA Young EP Ambassador for Spain. He is also one of the members of the central list of Experts for panels in Medical Devices for the European Commission.4

Neil T Srinivasan

Neil T Srinivasan

Dr Neil Srinivasan is a Consultant Cardiologist and Electrophysiologist and clinical academic at The Essex Cardiothoracic Centre. He is a Senior Lecturer at ARU medical school. He was previously a Locum Consultant at the Barts Heart Centre in London where he was the lead for Ventricular Tachycardia Ablation and The Lister Hospital where he was the lead for Electrophysiology.

 

Dr Srinivasan trained in cardiac rhythm management at The Heart Hospital in Marylebone and the Barts Heart Centre in London. During this time he undertook a PhD at the University College London (UCL) studying the mechanisms of VT/VF. He has undertaken a period of research at Washington University St Louis USA as part of this, developing non-invasive methods (ECGi) of studying the heart rhythm. He has also undertaken an observational VT fellowship in Leiden with Professor Katja Zeppenfeld. He has presented his work at national and international conferences and co-authored many major papers in the field. Recently, has pioneered the "Sense Protocol" method of functional substrate mapping in VT which has improved outcomes in VT ablation. 

Dr Srinivasan is a member of the Arrhythmia & Electrophysiology Review editorial board.
