Background and aim of the study: Although transcatheter aortic valve implantation (TAVI) is a steadily expanding treatment for the pathology of the aortic valve, its role in the replacement of native aortic valves following valve-sparing surgery has not been investigated.
Methods: Among 150 patients who underwent TAVI at the authors’ institution, three (2%) had a failed valve-sparing operation. The in-hospital outcome, mid-term mortality, and valvular function of the three patients were evaluated retrospectively. These patients, who were deemed at high surgical risk by the heart team, underwent TAVI for predominant severe aortic stenosis (n = 2) or pure severe aortic regurgitation (AR) (n = 1).
Results: A self-expandable CoreValve prosthesis was inserted via femoral access in all three patients. Based on
the Valve Academic Research Consortium 2 criteria (VARC-2), implantation was successful in all cases, with only one major access site complication and no more than mild residual AR. At a follow up of 13 ± 6 months there were no deaths and the mean transvalvular gradient remained low (7 ± 6 mmHg at discharge; 7 ± 4 mmHg at follow up), without any echocardiographic signs of valve deterioration.
Conclusion: The results obtained with this small patient cohort demonstrated the feasibility, safety, and favorable mid-term outcomes of TAVI for failed valve-sparing operations in high surgical risk patients. However, these findings must be validated in larger cohorts before extending such treatment routinely to this subset of patients.
