OBJECTIVES: To investigate the early and mid-term results of aortic root remodelling with external ring annuloplasty in acute type A aortic dissection.
METHODS: From January 2015 to April 2019, a total of 194 patients underwent emergency or urgent operation for acute type A aortic dissection in our hospital. Of these, outcomes in 18 patients who underwent valve-sparing aortic root remodelling with external ring annuloplasty were retrospectively evaluated.
RESULTS: The mean age of the 18 patients was 49 ± 14 years. Fourteen patients (78%) were men. Five patients had Marfan syndrome and 2 patients had bicuspid aortic valve. Two patients had coronary malperfusion and 1 patient had cerebral malperfusion. All 18 patients underwent aortic root remodelling with external ring annuloplasty. Cusp repair using central cusp plication was required in 9 patients. Concomitant procedures were hemiarch replacement in 8 patients, total arch replacement in 7 patients, partial arch replacement in 1 patient and coronary artery bypass grafting to the right coronary artery in 3 patients. Thirty-day mortality rate was 5.6% (1 of 18). Postoperative echocardiography showed aortic regurgitation of <1+ in all patients. During follow-up (mean 56 ± 41 months), 1 case of recurrent aortic regurgitation required aortic valve replacement.
CONCLUSIONS: Aortic root remodelling with external ring annuloplasty may be an appropriate treatment in middle-aged or younger patients presenting with acute type A aortic dissection.
