Preoperative computed tomography is associated with lower risk of perioperative stroke in reoperative cardiac surgery
Key result
Preoperative CT before cardiac reoperations is linked to a ~6% absolute reduction in perioperative stroke.
- P=0.003
- n=373
Why the study?
Preoperative CT use appears to be increasing among patients undergoing cardiac reoperations, but whether it reduces adverse outcomes and operative mortality was unconfirmed.

Implication
Preoperative CT was associated with lower perioperative stroke in reoperations; leaves open whether routine use improves outcomes in prospective trials.

Does preoperative computed tomography imaging reduce adverse outcomes and operative mortality in patients undergoing cardiac reoperations?
P
Population
373 patients undergoing cardiac reoperations evaluated for the impact of preoperative CT imaging on perioperative outcomes.

Main Result
Absolute Event Rate: 0% vs 5.6%
p-value: p=0.003
Routine preoperative CT imaging before cardiac reoperations is associated with a significantly lower risk of perioperative stroke, likely by optimizing surgical strategies.
Cite This Study
LaPar et al. (2011) conducted a cohort in cardiac reoperations (n=373). Preoperative computed tomography (CT) imaging vs. No preoperative CT imaging was evaluated on perioperative stroke (p=0.003). Preoperative CT imaging before cardiac reoperations was associated with a significantly lower rate of perioperative stroke compared to no preoperative CT (0.0% vs. 5.6%, P=0.003).
