Stenoses, Aortic Clinical Trial
Official title:
Safe and Fast Discharge With Acurate Valve in Low Risk Tavi Patients
Recent evidence from scientific literature supported the extension of TAVI procedures to lower risk populations. Despite its widespread usage, the expansion of TAVI into lower risk patient populations is still limited by complications and costs, with a large disparity between clinical trials and real-world scenarios suggesting still long hospitalizations after TAVI. This issue has got relevant implications in cost-effectiveness of the procedure, with many studies showing a more favourable cost profile associated with early discharges
In most cases, prolongation of hospital stay is mainly related to electrical, renal, vascular or neurological complications. With increasing operators' experience, careful procedure planning and technology improvement, procedure-related complications are reducing, with favourable effects in terms of postprocedural length-of-stay and related costs. This is particularly true for lower risk populations. Being surgery the gold standard for treating aortic valve disease in low-risk patients, the outcomes after TAVI in this population should meet high standards to be accepted. In particular, optimal results should not be limited to procedural success but last over time, ensuring both a long-life expectancy and a good quality of life. TAVI efficacy in this population should include the absence of residual paravalvular leaks, no need for permanent pacemakers, no cerebral embolism and the opportunity of easily re-accessing coronary arteries in the future. In particular, many questions have been raised about the difficulty of coronary re-access following use of the EvolutR/PRO valves compared to the Sapien 3 valves. Thus, valves with a larger open-celled design (ACURATE neo, Portico or JENA) are potentially more favourable for coronary access and could be considered in patients likely to require repeated re-access to coronary arteries. Acurate Neo Valve showed good procedural results in high-risk subsets of patients. Although not tested in large-scale trials involving low risk patients, due to its unique morphology it could offer peculiar advantages, compared to other devices, including: 1. Low permanent pacemaker rates 2. Easier coronary re-access 3. Low paravalvular leak rate (novel Neo 2 technology) The aim of this study was to report on the feasibility and safety of early discharge (defined as discharge within 48 hours from the procedure) of selected low-risk patients after transfemoral TAVI with the novel Acurate Neo2 valve platform ;
