RESEARCH:

• Acute Haemodynamic changes after balloon aortic valvuloplasty (BAV) and transcatheter aortic valve implantation (TAVI). (King’s College Hospital, London
• Observational study aimed to define the immediate haemodynamic changes after BAV and TAVI and to identify the mechanism of observed LV impairment
• Co-investigator in the following TAVI related studies: (King’s College Hospital Sapien-3 (Edwards) Valve PORTICO valve JENNA valve
• Risk scoring model for heart failure (Pilot study): (The Essex CTC)
• Small pilot study of 150 patients to try and develop a model for risk scoring to predict mortality and re-admission within 30 days of index admission in patients with heart failure.
