Open-heart transcatheter aortic valve replacement (TAVR) was successfully used as a rescue technique in 3 patients with massively calcified aortic roots where no other prosthesis was implantable.
Case Report (n=3)
Open-heart TAVR can serve as a successful rescue technique in complex aortic valve reoperations with heavily calcified roots where conventional prosthesis implantation is not feasible.
INTRODUCTION: Aortic homograft and stentless aortic root are helpful in acute infective endocarditis of the aortic valve as biological conduit when total root replacement is required. Reoperation for failure of aortic homograft and stentless aortic root remains challenging for the surgeon as the entire root can be heavily calcified. CASE PRESENTATION: Here, are reported, three cases of patients successfully treated with open-heart transcatheter aortic valve replacement (TAVR) whereas no other prosthesis was implantable due to a massively calcified homograft or stentless prosthesis. DISCUSSION: Open-heart TAVR avoided the risk of complete root replacement which is higher than redo aortic valve replacement (AVR). This rescue technique facilitated risky surgical procedure by combining the strengths of both TAVR and conventional AVR.
Leveille et al. (2018) conducted a case report in Failure of aortic homograft and stentless aortic root (n=3). Open-heart transcatheter aortic valve replacement (TAVR) was evaluated on Successful treatment. Open-heart transcatheter aortic valve replacement (TAVR) was successfully used as a rescue technique in 3 patients with massively calcified aortic roots where no other prosthesis was implantable.
