Key result
Concomitant replacement of the dilated ascending aorta during AVR did not increase operative mortality or morbidity compared to AVR alone, with similar late cardiac deaths (p=1.00).
Why the study?
Does concomitant replacement of the dilated ascending aorta during AVR reduce mortality and morbidity in patients with aortic stenosis and post-stenotic dilatation?
Population
134 patients with aortic stenosis and post-stenotic dilatation (aorta size ≥40 mm)
Comparison
Aortic valve and ascending aorta replacement vs Aortic valve replacement alone (n=92)
Design
Cohort
Follow-up
mean 3.5 ± 3 years

May support concomitant aortic replacement during AVR without added risk; leaves open need for randomized confirmation of benefit.

Does concomitant replacement of the dilated ascending aorta during AVR reduce mortality and morbidity in patients with aortic stenosis and post-stenotic dilatation?
p-value: p=1.00
Concomitant replacement of a dilated ascending aorta (≥40 mm) during AVR does not increase perioperative risk and may mitigate late mortality associated with progressive aortic expansion.
Lim et al. (2013) conducted a cohort in Aortic stenosis and post-stenotic dilatation (n=134). Aortic valve and ascending aorta replacement vs. Aortic valve replacement alone was evaluated on Operative mortality and morbidity, and late cardiac deaths (p=1.00). Concomitant replacement of the dilated ascending aorta during AVR did not increase operative mortality or morbidity compared to AVR alone, with similar late cardiac deaths (p=1.00).
