Medical School, University of Patras, Greece

MRCS (Edin)

FRCS (Cardiothoracic)

DM (Southampton)

SURGICAL EXPERIENCE AND INTERESTS

Mr Velissaris completed his Cardiothoracic Surgical Training in Southampton in 2008 and was appointed as a Consultant in Central Manchester University Hospital in 2009. He returned to University Hospital Southampton (UHS) in 2013 as a Consultant in Adult Cardiac Surgery. He performs all aspects of adult Cardiac Surgery, with the exception of transplantation, as there is no regional transplant unit here. The majority of procedures involve coronary bypass grafting but he also performs aortic and mitral valve replacements, mitral valve repairs and major thoracic aortic surgery.

Mr Velissaris’s personal operative results, and those of the Cardiac Unit at Spire Hospital Southampton and UHS, are available for public scrutiny on the website of the Society for Cardiothoracic Surgery in Great Britain and Ireland (www.scts.org). His personal operative outcomes, and those of the cardiac unit at Spire Southampton and UHS, have consistently been significantly better than expected when adjusted for surgical and operative risk. In the latest update for 2013 to 2016, Mr Velissaris was in the top 5 surgeons in the UK for number of cases performed (781 operations).

PROFESSIONAL AND RESEARCH INTERESTS

Mr Velissaris has a longstanding dedication to teaching and training junior surgeons in Cardiothoracic Surgery. He is currently Clinical and Educational Supervisor for all Core Surgical and Foundation Year trainees in Cardiothoracic Surgery at UHS. He is on both the Standard setting and Question Writing Groups for the final FRCS (Cardiothoracic) Intercollegiate examination.

Mr Velissaris has a longstanding involvement in clinical research in many aspects of Cardiac Surgery and Physiology. This has continued since he completed his Doctoral thesis (DM at the University of Oxford in 2007). He has numerous publications in peer reviewed journals on a broad range of adult and paediatric Cardiac Surgical topics. Details of this research can be found on the US National Library of Medicine website. (www.ncbi.nlm.nih.gov/pubmed)

BACKGROUND INFORMATION

Mr Velissaris gained his medical degree at the University of Patras, Greece, in 1995. In 1998 he obtained his Membership of the Royal College of Surgeons of Edinburgh. He undertook his Basic Surgical training in Cardiff and his initial Cardiothoracic Surgical training in London and Sheffield. Thereafter he did his higher Cardiothoracic Surgical Training at University Hospital Southampton. He undertook concomitant research at the University of Southampton and in 2007 he completed his Doctoral research thesis (DM). In 2007 he obtained his FRCS in Cardiothoracic Surgery and in 2008 his Certificate of Completion of Training in Cardiothoracic Surgery.


Surgical Outcomes Data

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.

Risk adjusted in-hospital survival for all surgeons

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 in comparison with the other units and surgeons in GB&I.
