Acute Aortic Dissection Determines the Fate of Initially Untreated Aortic Segments in Marfan Syndrome
Background—Aim of the current study was to investigate incidence and etiology of surgical interventions in primarily non-treated aortic segments after previous aortic repair in patients with Marfan syndrome (MFS).
Methods and Results—Retrospective analysis of 86 consecutive MFS patients fulfilling Ghent criteria that underwent 136 aortic surgeries and were followed at this institution in the past 15 years. Mean follow-up was 8.8±6.8y. Thirty-day, 6-months, 1-year and overall mortality was 3.5%, 5.8%, 7.0% and 12.8%, respectively. Ninety-two percent of patients initially presented with aortic root, ascending aortic or arch lesions, whereas 8% presented with descending aortic or thoraco-abdominal lesions. Primary presentation was acute aortic dissection (AAD) in 36% [77% type A, 23% type B] and aneurismal disease in 64%. Secondary complete arch replacement had to be performed in only 6% of patients without AAD, but in 36% with AAD (p=0.0005). In patients without AAD, 11% required surgery on primarily non-treated aortic segments [5 out of 6 patients suffered from type B dissection during follow-up], whereas in patients after AAD, 48% underwent surgery of initially non-treated aortic segments [42% of patients with type A and 86% of those with type B dissection] (p=0.0002).
Conclusions—The need for surgery in primarily non-treated aortic segments is precipitated by an initial presentation with AAD. Early elective surgery is associated with low mortality and re-intervention rates. Type B dissection in patients with MFS is associated with a high need for extensive aortic repair even if the dissection is being considered uncomplicated by conventional criteria.
