In this webinar, Dr Wright, an expert in real-world contact force ablation will discuss and provide an overview of the contact force radiofrequency ablation technique and its effect on lesion size.


Despite the widespread use of RF ablation in daily practice, it is perhaps surprising how much is still not understood about the basics of the biophysics underpinning RF ablation. Contact is fundamental to successful ablation, yet it is only in the last few years that we now have the tools to measure contact while performing ablations.


How we interpret this data among the myriad of factors that affect lesion formation is complicated by the endpoints that we have in clinical medicine. Recurrence of AF is a blunt tool, and even acute recurrence of conduction is relatively poor when we are trying to achieve permanent contiguous transmural lesions.



Dr Matthew Wright is a Consultant Cardiologist and Electrophysiologist at Guy’s and St Thomas’ Hospital, London UK and is section editor for Radcliffe Cardiology’s online section for real world contact force ablation. He has published over 100 scientific papers and books, is a regular conference speaker and performer of ‘live’ ablation cases and was awarded the Sir Thomas Lewis Cardiology prize.

His areas of interest include patients with complex arrhythmias, atrial fibrillation, atrial tachycardia and ventricular fibrillation. His particular research areas include the real-time visualisation of ablation lesions, near field ultrasound to assess transmural lesions during ablation and the integration of imaging and electrophysiology.

Dr Afzal Sohaib is a Consultant Cardiologist at Barking, Havering, & Redbridge University Hospitals NHS Trust and the Bart's Heart Centre in London. He completed a British Heart Foundation Clinical Research Training Fellowship at the International Centre for Circulatory Health at NHLI and continues to work with the team at NHLI. His research interests are in cardiac electrophysiology and devices.

Dr Sohaib attained his medical degree from University College London and was a Betuel Prize winner after finishing in second place in the University of London Gold Medal Examination. He trained in cardiac electrophysiology and device implantation at the Hammersmith Hospital, Harefield Hospital, and the Royal Brompton Hospital. He has EHRA Certification in Cardiac Electrophysiology and EHRA Certification in Pacemakers and ICDs.

Creating a lesion and treating AF requires a number of variables to be understood, and this webinar will inform and educate on:

  • How irrigation rates and power delivery can be optimised.
  • An historical overview.
  • An outline on the role of contact force with a look at some real life case studies to prove the data.
  • It will also consider the role of contact force in the future.
  • Cardiologists/interventional specialists
  • Allied healthcare professionals such as physiologists, technicians or nurses
