Why the study?
Does aortic cross-clamping and unclamping alter ventricular performance during abdominal aortic aneurysm repair?
Population
23 patients undergoing infrarenal abdominal aortic aneurysm repair
Comparison
Aortic cross-clamping and unclamping during… vs Baseline (before skin incision)
Design
Cohort
Follow-up
Intraoperative (up to after skin closure)
Authors

Reversible LV changes during aortic clamping warrant intraoperative vigilance; leaves open whether afterload modulation improves outcomes in prospective trials.
Does aortic cross-clamping and unclamping alter ventricular performance during abdominal aortic aneurysm repair?
Aortic cross-clamping during abdominal aortic aneurysm repair causes significant but reversible changes in left ventricular function and volumes, primarily driven by variations in afterload.
Harpole et al. (1989) studied this question.
