Wendler Olaf

GMC: 6047291

Hospital(s): King's College Hospital NHS Foundation Trust

Special Interests: Adult Cardiac Surgery

After his cardiothoracic surgical training at the Medical School Hannover/Germany, Professor Wendler worked as staff surgeon at the Heart Center Leipzig/Germany. He later became deputy of the Cardiothoracic Department at the University Hospital Saarland/Germany, where he completed his PhD on complete arterial revascularisation. In 2004 Professor Wendler was appointed at King’s College Hospital, and held the position of clinical director for cardiovascular services from 2006 until 2012, when he was promoted Professor of Cardiac Surgery at King’s College London. In 2018 he was appointed as chair of the heart and vascular institute of the Cleveland Clinic London, planned to open for in hospital patient treatment beginning 2021.

Professor Wendler has a particular interest in the treatment of heart valve disease and is sub-specialised in valve repair techniques including the aortic root, mitral and tricuspid valve. Due to his particular expertise in this area, Professor Wendler runs a service particularly specialised in the treatment of complex multiple heart valve surgery including patients with carcinoid disease. Through his close collaboration with the vascular surgical department and interventional radiology he has established King’s College Hospital as one of the major centers for thoracic aortic surgery in London.

In 2007 Professor Wendler performed the first transapical Transcatheter Aortic Valve Implantation (TAVI) in the UK and has established King’s College Hospital as one of the major international centers for this innovative treatment. Over recent years the King’s Heart Team performed the first TAVI in a failing aortic bioprosthesis (2008) and the first transcatheter valve implantation in a failing mitral bioprosthesis (2010) in the UK.

Number and type of operations performed

This graph shows the number and percentage of each type of heart surgery done by this consultant surgeon. The number of operations is shown in the line going up the left hand side. The percentage (%) underneath each coloured bar shows how much of this consultant's heart surgery is made up each procedure type.

The 'key' underneath the graph shows what procedure(s) each coloured bar shows. The abbreviations used are explained below:

  • Isolated: This procedure has been carried out on its own. No other procedures were done during the same operation.
  • CABG: Coronary artery bypass grafting
  • AVR: Aortic valve replacement
  • MV: Mitral valve procedure

You can find out more about these procedures in the 'About cardiothoracic surgery' section. If you or someone you know if having heart surgery, it may be helpful to know whether the consultant does lots of that procedure. If you have questions or concerns about the number of procedures being done at your hospital, you should speak to your heart surgeon.

In-hospital survival rate (risk adjusted)

This graph shows the percentage of patients who survived their operation and left hospital alive. This is the 'In-hospital survival rate'. Some patients are more unwell than others and some need more complex operations. Hence, hospitals and consultants perform a range of cardiac operations and the type of patients they operate on can differ. So that we can make fair comparisons between them, the survival rates have been 'risk adjusted' to take into account the illness of the patient and the complexity of the operation. The dot on the graph shows the risk-adjusted survival for the unit/surgeon you have selected and the number of operations performed over the last 3 year period. The blue line indicates the predicted survival and the red dotted lines the range of results expected, worked out by complex statistics.

Average patient risk profile

Some risk factors like age, gender, and other medical problems can affect the outcome of heart surgery.

Each of the graphs below shows what percentage of this consultant's patients have each risk factor (light blue bar on the left) next to the average for the whole of the UK (dark blue bar on the right). This can tell you whether the consultant operates on high risk patients in general, and whether they specialise in doing particular types of complicated surgery, like operations on the thoracic aorta.

You can find out more about the risk factors in the 'About cardiothoracic surgery' section.
