The UK cardiac surgical register, 1977-82.

Data for 1977-82 obtained from the Cardiac Surgical Register, established by the Society of Thoracic and Cardiovascular Surgeons of Great Britain and Northern Ireland in 1977, were analysed for trends in incidence and mortality of cardiac surgery and regional workload in the United Kingdom. Operative mortality for most types of cardiac operation showed a general decline. The numbers of operations performed for valvular and congenital heart disease had remained unchanged, but a striking increase had occurred in the number of coronary bypass graft operations: 2297 in 1977 to 6008 in 1982. The figure for 1982, representing an annual rate of 107 operations per million population, was still well below that for other countries such as Australia (410 per million in 1982) and the United States (750 per million in 1981). A wide variation was seen in the regional provision of cardiac surgical services within the United Kingdom. This was particularly appreciable for coronary bypass graft surgery, in which there was a 10-fold difference in numbers of operations performed between the various regions. The UK Cardiac Surgical Register provides an important source of information on trends within the specialty that could well be followed by other surgical specialties.
