Cardiac surgery during wartime in Israel

The war that began on October 7th, 2023, has impacted all major tertiary medical centers in Israel. In the largest cardiac surgery department in Israel there has been a surprising increase in the number of open-heart procedures, despite having approximately 50% of surgeons recruited to military service. The purpose of this study is to characterize this increase in the number of operations performed during wartime and assess whether the national crisis has affected patient outcomes.
