BackgroundThe advent of transcatheter aortic valve implantation (TAVI) has broadened the management options for severe aortic stenosis. The indications for TAVI are narrow. Selecting those that will benefit most from this intervention warrants careful consideration and input from cardiologists, anaesthetists and cardiac surgeons familiar with TAVI and surgical aortic valve replacement (SAVR).AimsThe aims of this paper were to assess the feasibility of establishing a high-risk aortic clinic in Ireland, and report stratification of the referred group into those suitable for SAVR, TAVI and conservative management.MethodsPatient data was prospectively collected by a dedicated clinical nurse specialist. ANOVA was used to assess variance in means between groups. Analyses were performed using IBM SPSS v20 (Armonk, NY: IBM Corp.).ResultsA total of 105 patients were assessed. Eighty-five patients were deemed suitable for TAVI, 9 (10.5 %) died awaiting the procedure and a further 6 (7 %) declined intervention. Eleven (10.5 %) underwent conventional SAVR, 1 (0.9 %) a balloon valvuloplasty, 4 (3.8 %) entered surveillance and 4 (3.8 %) were declined treatment.ConclusionsEstablishment of a high-risk aortic clinic is feasible in the Irish context. The advent of TAVI has reduced the proportion of patients denied intervention to a minority. Despite being considered high risk, a number of patients were suitable candidates for SAVR. Measuring frailty continues to provide a challenge; a TAVI-specific frailty assessment tool would be advantageous to patient stratification.
