Cardiac Rhythm Management

Consultant Cardiologist and Clinical Lead for Cardiac Electrophysiology at Oxford University Hospitals NHS Foundation Trust.

Practices in all aspects of cardiac rhythm management including catheter ablation, complex device therapy and left atrial appendage occlusion.

Leads an active commercial research programme with an excellent team of Research Nurses, Data Administrators and Cardiac Physiologists, supported by the Thames Valley CRN. PI of multiple NIHR portfolio studies in AF ablation (STAR-AF2, UNCOVER-AF, RECOVER-AF, DISCOVER-AF,); Heart failure device therapy (CARDIOMEMS-OUS, MORE-MPP CRT, SYNC-AV, LV-Only, SOLVE-CRT, WiSE-CRT registry); leadless pacing (NANOSTIM, AVIER-DR IDE) and left atrial appendage occlusion (EWOLUTION, ASAP-TOO, CHAMPION-AF, ICE-LAAO). 

Leads a number of investigator-led programmes with PhD students that are exploring the role of charge-density global-non-contact mapping to determine the mechanisms, substrate and potential ablation targets for atrial fibrillation (collaboration with Acutus Medical); the innovative approach of "as-required" oral anticoagulation in low-burden atrial fibrillation (the SMART-Alert study, funded by a Heart Research UK New and Emerging Technologies grant), and stereotactic radioablation to treat cardiac arrhythmias (collaboration with GenesisCare).
