Prognostic Factors of Patients Undergoing Redo Cardiac Surgery

Redo cardiac surgery is associated with an increased risk of postoperative morbidity and mortality. Patients undergoing redo cardiac surgery are becoming increasingly complex due to multiple comorbidities, adherence of mediastinal structures to the undersurface of the sternum as well as the spatial location of patent bypass grafts relative to the route of entry. Association estimates between baseline characteristics and outcomes in those cohort are imprecise. The aim of this study is to identify prognostic factors associated with redo cardiac surgery which may help physicians predict clinical outcomes and guide their treatment decision.
