Special Interests: Adult Cardiac Surgery, Thoracic Surgery
Dheeraj Mehta was educated at St Dunstan’s College, London. He undertook undergraduate medical training at Guy’s Hospital Medical School, London (1984-1990), and following basic surgical and research experience, he entered cardiothoracic training at The Royal Brompton Hospital and Bristol Heart Institute (1997-2003). This included a fellowship in adult cardiac and transplant surgery at St Vincent’s Hospital, Sydney, Australia (2002-2003). He was appointed Consultant Cardiothroacic Surgeon at the University Hospital of Wales in 2003.
He has extensive specialist expertise in ‘off-pump’ coronary artery bypass surgery and total arterial revascularisation, in addition to undertaking the spectrum of adult cardiac surgical procedures, including mitral valve repair & replacement, aortic valve replacement and surgery of the ascending aorta, tricuspid valve surgery, and surgery for atrial fibrillation. He is one of two surgeons on the Institution’s TAVI team.
He has a keen interest in training, reflected in his role as Training Programme Director for Cardiothoracic Surgery in Wales, and educational supervisor to both core and higher surgical trainees.

Risk-adjusted in-hospital survival rate
This graph shows the “in hospital” survival rate of patients who are operated on by the individual surgeon/unit you have selected. “In hospital” means time the patient is in the hospital where they have had their operation. It does not include any time that patients may have spent in other hospitals, either before or after their heart operation.
The data has been through a complex methodology, including the variations in patient risk factors in order to give you a comparative base from which to work from. This means that the survival rates take into account the type and risk of patients being operated on for each surgeon/unit. This is known as risk adjusted survival.
The vertical axis shows the GMC number of the surgeon or the Hospital identifier. In brackets is the total number of patients operated on by the surgeon/unit and the percentage of patients for whom the survival is known. The horizontal axis is the percentage survival. The dashed vertical line shows the risk adjusted survival rate for the UK as a whole. The solid black horizontal line represents the surgeon/unit. What is important here is that the horizontal line crosses the vertical dashed line. If this occurs, it means that the surgeon/unit are within the expected outcomes given the case-mix and risk factors of the patients they operate on.
The icons that sit on the horizontal line should give you more information about your surgeon/team.
The open square is the survival rate with no risk adjustments:
The X is the predicted survival with adjustments
The solid dot is the survival probability after the methodology has been applied.
- If the solid dot is red it means survival is worse than expected
- If the solid dot is black it means that it is within limits
- If the solid dot is green it means that there is significantly higher survival than expected
There is a lot of information on these plots, but the takeaway message is that if the solid black line crosses the dashed vertical line then the survival rate for the surgeon/unit is within expectations and that there is no reason for any concern.
