| Summary: | Background: In this study, we present recent trends in heart valve surgery in Korea
through analyses of data from the Korea Heart Valve Surgery Registry (KHVSR).
Methods: We enrolled 8,981 patients who were registered in the KHVSR from 2017 to
2020. Yearly trends in patients’ baseline characteristics, surgical profiles, and early mortality
rates were explored. The observed/expected mortality ratio (O/E ratio), calculated from the
actual mortality in the KHVSR and the predicted mortality estimated using the EuroSCORE
II, was also analyzed.
Results: The proportion of aortic valve surgery significantly increased from 56.8% in 2017
to 60.3% in 2020. The proportion of all combined procedures and minimally invasive surgery
significantly increased over the 4-year study period. The operative mortality rate was
2.9% in the entire cohort, while mitral valve repair showed the lowest mortality risk (0.9%).
The mortality rates of isolated aortic valve replacement (AVR) significantly decreased from
2.1% in 2017 to 0.8% in 2020 (p=0.016). Overall, the O/E ratio was 0.784 (95% confidence
interval [CI], 0.677–0.902) demonstrating significantly lower actual mortality risks than expected
based on the EuroSCORE II. In particular, the O/E ratios were as low as 0.364 (95%
CI, 0.208–0.591) for isolated AVR.
Conclusion: The recent data from the KHVSR showed increasing trends for complex procedures
and minimally invasive surgery in heart valve surgery in Korea, and demonstrated
remarkably low risks of operative mortality. |
