Virtual consultations:

I was initially appointed as Consultant Cardiologist at University College London Hospitals in 2013. I have extensive experience in all aspects of general adult cardiology and particular specialist expertise in the care and management of patients with coronary artery disease.

I see patients who are concerned about symptoms such as chest pains, breathlessness, palpitations, dizziness and faints. I am involved in the long term care of patients with heart conditions including coronary artery disease, heart valve problems, heart rhythm distubances, high blood pressure and heart failure.

I also regularly review patients with heart-related concerns prior to (non-heart related) surgery and other planned treatments.      

I undertake keyhole-type procedures for the diagnosis and treatment of patients with suspected or known heart artery problems. This includes advanced assessment of heart arteries using state-of-the art scanning techniques inside the vessels. I also perform treatment of heart artery disease (where appropriate) with ballooning and stents.

In 2015, I was also appointed as a consultant at the new Barts Heart Centre at Saint Bartholomew’s Hospital in London.

In addition to my clinical work, I am actively involved in research on heart diseases. I am an Honorary Associate Professor in the Insitute of Cardiac Sciences at University College London (UCL). I have published extensively on factors that can influence outcome and survival after heart attacks.
