Key result
Perioperative hypotension during TAVI linked to ~11% higher absolute in-hospital mortality, with diabetes predicting risk.
Why the study?
Although reduced EF and low baseline blood pressure are linked to hemodynamic instability during TAVI, the role of metabolic comorbidities and procedural factors remains less well established.
Cohort (n=123)
Absolute Event Rate: 12.9% vs 1.9%
p-value: p=0.027
Perioperative hypotension is common during TAVI, strongly associated with early mortality, and independently predicted by diabetes mellitus, reduced ejection fraction, lower baseline diastolic blood pressure, and longer procedural duration.
No takes yet. Share an insight, caveat, or question.
May warrant closer hemodynamic monitoring in TAVI; leaves open whether BP optimization reduces mortality in diabetic patients.
Demirbaş et al. (2025) conducted a cohort in Transcatheter aortic valve implantation (TAVI) (n=123). Perioperative hypotension vs. No perioperative hypotension was evaluated on In-hospital mortality (p=0.027). Perioperative hypotension during TAVI was associated with significantly higher in-hospital mortality (12.9% vs. 1.9%, p=0.027), with diabetes mellitus identified as an independent predictor.
