Abstract Background: The aim of this study was to evaluate the longer-term results of bicuspid aortic valve (BAV) repair with or without aortic root replacement. Methods: From 1999 to 2017, 142 patients with or without aortic root dilatation who underwent repair of a regurgitant BAV were included in the study.
Ninety-four patients underwent isolated BAV repair (Group 1; median age 43 years) and 48 patients underwent valve-sparing aortic root replacement plus BAV repair (aortic valve reimplantation-Group 2; median age 48 years). Median clinical follow-up time was 5.9 years (range 0.5-15) in Group 1 and 3 years (range 0.5-16) in Group 2, respectively.
Results: In-hospital mortality was 1% in Group 1, and 2% in Group 2 (p = .6). The 5- and 10-year survival was 93 +- 2.9% and 81 +- 5.8% in Group 1 and 96 +- 3.1% and 96 +- 3.1% in Group 2, respectively (p = .31).
Eleven patients of Group 1 (1.7%/ patient-year) and five patients of Group 2 (2.2%/patient-year) underwent reoperation of the aortic valve (p = .5). The 5- and 10-year freedom from reoperation were 93.0 +- 2.1% and 77.1 +- 7.1% in Group 1 and 93.0 +- 5.0% and 76.7 +- 9.6% in Group 2 (p = .83), respectively.
At the latest follow-up, only two patients of Group 1 and 1 patient of Group 2 had AV regurgitation = 2° (p = .7). The cumulative linearized incidence of all valve-related complications (bleeding, stroke, endocarditis, and reoperation) was 2.9%/patient-year in Group 1% and 4%/patient-year in Group 2, respectively (p = .6).
Conclusions: Isolated BAV repair and combined aortic valve reimplantation plus BAV repair provide good clinical longer-term outcomes with relatively low reoperation rate and durable valve function.
