As a private healthcare provider this hospital’s page is different from those of NHS hospitals featured on this site. Because private outcome data cannot be accurately compared to NHS practice, it has been analysed separately. Therefore this hospital’s mortality rate is displayed with the two other private hospitals that contribute to the National Adult Cardiac Surgery Audit. For the same reason, surgeons who operate in private hospitals are not listed on this page. Their details can be found on the hospital’s own website by following this link.

About the unit

This world famous hospital has an international reputation for its adult and paediatric cardiac surgical programme. Established in 1965, its cardiac facilities include mono and bi-plane cardiology investigation labs, a 5-bed high dependency unit and a 12 bedded ITU.

Services provided

Adult Cardiac Surgery
Thoracic Surgery
Congenital Cardiac Surgery

Rehabilitation and follow up

Follow up is generally 6 weeks to the appropriate surgeon with a discharge back to the GP as required. Cardiac rehabilitation is provided locally for catchment patients or appropriate contact is made with the local hospital's rehab team to ensure continuity of care.


There are four London Underground stations nearby and the hospital is close to four mainline train stations. There are also two NCP car parks nearby. Wheelchair access is available.

Cardiac Outcomes

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.

For example

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.
