"Type A Aortic Dissection in Marfan Syndrome"
http://circ.ahajournals.org/content/129/13/1381.abstract
"Conclusions—Emergency surgery for type A dissection in patients with Marfan syndrome is associated with low in-hospital mortality. Failure to extend the primary surgery to aortic root or arch repair leads to a highly complex clinical course. Aortic root replacement or repair is highly recommended because supracoronary ascending replacement is associated with a high need (>40%) for root reintervention."
