Radiation-Induced Aortic Stenosis
Key result
Transcatheter aortic valve replacement showed a trend toward decreased mortality and fewer major complications compared to surgical aortic valve replacement in patients with radiation-induced AS.
Why the study?
Radiation-induced aortic stenosis is an increasingly recognized entity that poses particular therapeutic challenges, and optimal management strategies remain undefined.
Does TAVR reduce mortality and major complications compared to SAVR in patients with radiation-induced aortic stenosis?

Implication
TAVR may warrant consideration over SAVR in radiation-induced AS; leaves open need for randomized trials to confirm mortality trends.

Mortality and major complicationshard clinical
TAVR appears to be a safe and effective alternative to SAVR for patients with radiation-induced aortic stenosis, potentially offering lower mortality and fewer complications.
Limitations
- Rare and unexpected complications may occur after TAVR from the deleterious effects of radiation on mediastinal structures.
- More studies are needed to identify the optimal way of managing patients with radiation-induced AS, and algorithms are needed for planning these complex interventions.

Belzile‐Dugas et al. (2023) conducted a review in Radiation-induced aortic stenosis. Transcatheter aortic valve replacement (TAVR) vs. Surgical aortic valve replacement was evaluated. Transcatheter aortic valve replacement showed a trend toward decreased mortality and fewer major complications compared to surgical aortic valve replacement in patients with radiation-induced AS.
