Key result
Primary root replacement in Marfan type A dissection is linked to ~74% fewer reoperations versus supracoronary replacement.
Why the study?
Does the extent of initial surgical repair reduce the need for long-term aortic reinterventions in patients with Marfan syndrome and type A aortic dissection?
Cohort (n=74)
Yes
Does the extent of initial surgical repair reduce the need for long-term aortic reinterventions in patients with Marfan syndrome and type A aortic dissection?
Absolute Event Rate: 79% vs 20%
In Marfan syndrome patients with type A aortic dissection, initial aortic root replacement or repair is highly recommended to prevent the high rate of future root reinterventions associated with supracoronary ascending replacement.

Supports initial root replacement in Marfan type A dissection to lower reoperation risk; extends cohort evidence without establishing causality.
Rylski et al. (2014) conducted a cohort in Stanford type A aortic dissection in Marfan syndrome (n=74). Aortic root replacement or repair (composite valved graft or valve-sparing aortic root replacement) vs. Supracoronary ascending replacement was evaluated on Freedom from aortic root reoperation at 20 years. Primary aortic root replacement or repair in Marfan syndrome patients with type A dissection resulted in 79% freedom from root reoperation at 20 years, compared to 20% with supracoronary ascending replacement.
