Key result
Conventional aortic valve replacement in patients aged 70 years or older demonstrated an overall operative mortality of 3.9%, which was lower than the expected STS-PROM mortality of 4.8%.
Why the study?
Does conventional aortic valve replacement provide durable survival and low operative mortality in elderly patients (≥70 years) with aortic stenosis?
Cohort (n=308)
No
Does conventional aortic valve replacement provide durable survival and low operative mortality in elderly patients (≥70 years) with aortic stenosis?
Absolute Event Rate: 3.9% vs 4.8%
Conventional aortic valve replacement in patients aged 70 and older demonstrates low operative mortality and durable long-term survival, serving as a benchmark for transcatheter approaches.
No takes yet. Share an insight, caveat, or question.
Supports conventional AVR in elderly patients with mortality below predictions; leaves open randomized comparisons to transcatheter approaches.
Yamane et al. (2011) conducted a cohort in Aortic stenosis (n=308). Conventional aortic valve replacement (AVR) vs. Expected mortality (STS-PROM) was evaluated on Operative mortality (death during hospitalization or within 30 days after surgery). Conventional aortic valve replacement in patients aged 70 years or older demonstrated an overall operative mortality of 3.9%, which was lower than the expected STS-PROM mortality of 4.8%.
