Key result
In-hospital mortality following heart valve surgery decreased from 7.1% in 1990-1999 to 1.8% in 2010-2019, with significant reductions in infectious complications and inadequate myocardial protection.
Why the study?
The study was conducted to determine the structure and trends of in-hospital mortality in surgery for acquired heart valve disease over a 30-year period.
Does technical progress and accumulated surgical experience over time reduce in-hospital mortality in patients undergoing acquired heart valve surgery?
Observational (n=3,108)
Does technical progress and accumulated surgical experience over time reduce in-hospital mortality in patients undergoing acquired heart valve surgery?
In-hospital mortality for acquired heart valve surgery has significantly decreased over a 30-year period, reflecting improvements in surgical technique and myocardial protection.
Mortality decline in valve surgery may reflect experience gains; extends trends but leaves open confounding in this cohort.

Ivanov et al. (2022) conducted an observational in Acquired heart valve pathology (n=3,108). Heart valve surgery in 2010-2019 vs. Heart valve surgery in 1990-1999 and 2000-2009 was evaluated on In-hospital mortality. In-hospital mortality following heart valve surgery decreased from 7.1% in 1990-1999 to 1.8% in 2010-2019, with significant reductions in infectious complications and inadequate myocardial protection.
