Dr Vipin Zamvar, born in 1965, graduated from Grant Medical College, Mumbai in 1988. He completed his initial general surgical training at Sir JJ Hospital,Mumbai, and speciality cardiothoracic surgical training in the UK. He has been a Consultant Cardiothoracic Surgeon at the Royal Infirmary of Edinburgh since 2002.
He has a joint cardiac and thoracic surgical practice, and his main areas of interests are Coronary Artery Bypass Graft Surgery, Off-Pump Surgery, and Minimally Invasive Cardiac and Thoracic Surgery, Aortic Valve Surgery and Lung Cancer Surgery.
His main research interests are in the field of Coronary Artery Bypass Graft Surgery. He is the primary investigator of many multi-center trials exploring the issues of conduits and techniques used in Coronary Artery Surgery.
He continues to train and mentor surgeons in cardiac and thoracic surgery. His other interests include audit and quality improvement in cardiothoracic surgery.
He is a member of numerous national and international societies, and has published several professional papers, and text-book chapters, and has made numerous presentations on cardiothoracic surgical topics. He has been the Editor-in-Chief of the Journal of Cardiothoracic Surgery since its inception in 2006. He is on the editorial board of the Heart Surgery Forum, and The Physician. He also edits The Bulletin for the Society for Cardiothoracic Surgery in Great Britain and Ireland.
He is the current President of the World Society of Cardiothoracic Surgeons.

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.
