News

Karolinska University Hospital is among the best hospitals in the world in terms of survival after cardiac surgery.x

In 2021, the mortality rate for cardiac surgery was 1.4 percent, with 1,035 performed surgeries. In 2020, the mortality rate for cardiac surgery was 1.1 percent out of 1,026 surgeries.

For example, Cleveland Clinics, ranked No. 1 in the US for 27 consecutive years for cardiac care, had a mortality rate of 1.6 percent in 2021 and 1.3 percent in 2020.

The number of procedures per surgeon makes the difference

– An important factor in this is the number of procedures per surgeon. In our hospital, all specialist cardiac surgeons performed over 100 cardiac surgeries. “The surgeon who performed the most operations performed 222 procedures, and I, as Director, performed 121 procedures,” says Peter Svenarud, Consultant and Director of Karolinska's Thoracic Surgery Department.

Over the past five years, the mortality rate for cardiac surgery at Karolinska University Hospital has dropped significantly. At the same time, the number of cardiac surgeries increased.

– We work with continuous quality improvement in all parts of a well-functioning healthcare chain. We have well-developed surgical methods and optimised surgical planning. The waiting time for heart surgery is now only 13 days, says Peter Svenarud.
