Jahangiri Marjan

GMC: 3276042


Special Interests: Adult Cardiac Surgery

Marjan Jahangiri graduated in medicine from University College Hospital, London. Subsequently, she completed her general surgical training at University College London and affiliated hospitals. She embarked on a career in Cardiothoracic Surgery. She trained at the London Chest, St Bartholomew’s and the Royal Brompton Hospitals in London. She was awarded a research fellowship at the William Harvey Laboratories at St. Bartholomew’s Hospital and Medical School. She then subspecialized in paediatric and adult congenital surgery at Great Ormond Street Hospital and Children’s Hospital in Boston, Harvard. She is the first female professor of cardiac surgery in the United Kingdom and Europe.

She was appointed as Consultant Cardiac Surgeon and Senior Lecturer in 2001 at St. George’s Hospital, University of London. She was appointed Professor of Cardiac Surgery at University of London in 2007. Her major interests in the field of clinical cardiac surgery include: surgery of the aorta, including aneurysms, especially major and major complex cases (Marfan), aortic valve surgery, minimally invasive aortic valve procedure, beating heart surgery, and cardiac surgery in pregnant patients. She has contributed to advances in protecting neurocognition and has been instrumental in developing minimally invasive surgery.

Marjan Jahangiri operates on 280-300 cases per annum. This is one of the largest cardiac surgical services in the United Kingdom. Her overall mortality for all cases including complex and major complex heart operations is 1.5 – 3.5%.

She has been the author of several reviews, book chapters, manuscripts, abstracts and communications. She is a regular invited speaker at national and international conferences. She is the principal investigator in a number of clinical research trials. At any one time 5-7 full time research fellows work under her direct supervision. In the past 10 years, 17 research fellows have qualified under her supervision (11 MD Res and 6 PhD). Her main area of research includes diseases of the aorta and aortic valve, minimally invasive aortic valve surgery, neurocognition and quality of life after cardiac surgery. She has chaired multi-disciplinary guidelines on management of coronary artery disease, aortic valve (minimally invasive) and aortic disease.

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.
