Background A history family of aortic dissection was considered as a risk factor for aortic dissection in patients with Marfan syndrome with a FBN1 mutation. Objectives Evaluate whether a family history of aortic dissection is a risk marker for dissection in this population Methods Retrospective study of patients coming to the reference centre between 1996 and 2018, carrying a FBN1 gene mutation. Pedigrees were obtained for each patient, and familial screening actively pursued. Patients with a family history of aortic dissection were compared with patients without family history of aortic dissection. Results 1700 patients (age 33.2 (±17) years, 51% women) with a FBN1 gene mutation were included. 145 (8,5%) patients underwent aortic dissection at a mean age of 37.9 (±11.4) years and 323 (19%) patients had been operated at 33.8 (±13.9) years. 481 patients had a family history of aortic dissection, including 38 who dissected themselves, and 88 who underwent surgery. 1219 had no family history of aortic dissection, including 107 who dissected themselves, and 235 who underwent surgery. Therefore, the personal risk for aortic dissection was similar in patients with and without a family history of aortic dissection (38/481, i.e. 7.9% vs 107/1219, i.e. 8.8%), as was the personal risk for prophylactic aortic surgery (88/481, i.e. 18.3% vs. 253/1219, i.e. 17.2%), and the risk for either aortic dissection or prophylactic aortic surgery (118/481, i.e. 24.5% vs. 328/1219, i.e. 26.9%). Conclusions In Marfan syndrome with a FBN1 gene mutation, a family history of aortic dissection is not a marker of aortic disease severity. Funding Acknowledgement Type of funding sources: None.
