Special Interests: Adult Cardiac Surgery, Thoracic Surgery
Mr Chukwuemeka qualified from the University of London (St. Thomas’ Hospital Medical School) in 1992 and completed general and cardiothoracic surgical training in London and in Toronto. He is a Consultant Cardiothoracic Surgeon and Chief of Service (Clinical Director) of Cardiology, Cardiothoracic and Vascular Surgery at Imperial College Healthcare NHS Trust and Honorary Senior Lecturer at the National Heart and Lung Institute.
His practise encompasses the broad spectrum of heart surgery and his specialist interests include surgery for ischaemic heart disease (coronary artery bypass surgery), aortic valve surgery (including TAVI) and surgery for thoracic aortic aneurysms. He has pioneered the development of sutureless aortic valve implantation in the UK.
Between 2008 and 2012 he served on the Clinical Expert Panel in Cardiac Surgery, the Cardiovascular Clinical Leadership Advisory Group, and the Future Cardiac Technologies Advisory Group at NHS London as well as the Cardiac Steering Group for the Northwest London Cardiac and Stroke Network. He is currently co-chair of the Cardiac Advisory Group at NHS London.
He is currently a member of member of the Executive Committee and the Adult Cardiac subcommittee of the Society for Cardiothoracic Surgery in Great Britain and Ireland. He serves as Regional Specialty Advisor in Cardiothoracic Surgery (Royal College of Surgeons of England) and is Director of the Cardiothoracic Skills Course at Royal College of Surgeons of England. He served as a member of the Medical Technologies Advisory Committee at the National Institute for Health and Care Excellence (NICE) from 2012-2015 and was also appointed to the National Clinical Reference Group for Cardiac Surgery in 2013.

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.
