  • sensitivity analyses in the genetically positive subgroup

Authors' conclusion

In this multicenter Marfan cohort, men had a greater burden of aneurysmal disease, atrial arrhythmias, sustained ventricular tachycardia, and aortic intervention, whereas dissection prevalence was similar between sexes.

Study context

Population
Adults with confirmed marfan syndrome (MFS) evaluated from 2018 to 2024 at Mayo Clinicmen 443 · women 340
Participants
783 patients
Exposure
men and women with confirmed MFS
  • menn = 443
  • womenn = 340

Main finding

As reported in the abstract

ascending aortic aneurysm

Observational data: associations, not effects.

Further findings

any aneurysm

any extra-aortic aneurysm

atrial fibrillation

atrial flutter

sustained ventricular tachycardia

aortic root surgery

mitral valve prolapse

  • any aneurysm: all P ≤ 0.001
  • any extra-aortic aneurysm: all P ≤ 0.001
  • atrial fibrillation: all P < 0.05
  • atrial flutter: all P < 0.05
  • sustained ventricular tachycardia: all P < 0.05
  • aortic root surgery: all P < 0.05
  • mitral valve prolapse: P = 0.028

Dissection prevalence

Dissection prevalence was similar by sex

aneurysmal burden, atrial fibrillation, sustained ventricular tachycardia, and aortic root surgery (adjusted)

After adjustment, male sex remained associated with aneurysmal burden, atrial fibrillation, sustained ventricular tachycardia, and aortic root surgery
