Special Issue Information

Dear Colleagues,

During the last decade, scientific validation of Transcatheter Aortic Valve Implantation (TAVI) has considerably changed the management of patients with symptomatic aortic stenosis. The introduction of new technologies and the evolution of TAVI devices have already expanded current indications and refined clinical outcomes.

This Special Issue aims to address emerging challenges and knowledge gaps in the field of TAVI, focusing on expanding clinical indications, optimizing outcomes, and advancing Valve-in-Valve and TAVI-in-TAVI techniques.

We are particularly interested in studies that explore TAVI in special populations, investigate long-term durability and patient–prosthesis mismatch, and examine outcomes and decision-making for Valve-in-Valve and complex repeat-TAVI procedures.

We welcome the submission of original research, review articles, and real-world data that deepen our understanding of TAVI applications and outcomes. Topics of interest for this Special Issue include patient selection, procedural innovations, technical challenges, and long-term durability.

Background: There are limited data on the impact of right heart failure (RHF) on patients undergoing transcatheter aortic valve implantation (TAVI). We investigated the mortality, in-hospital complications, length of stay, and total hospitalization charges for TAVI admissions, with and without RHF. Methods: We analyzed the National Inpatient Sample data from 2018 to 2022. The International Classification of Diseases–Tenth Revision (ICD-10) codes were used to define the patient cohorts. Propensity score weighting was used to balance patient demographic, hospital-level, and comorbidity data. Results: From 2018 to 2022, there were 383,860 TAVI admissions, among which 1915 (0.50%) had the presence of RHF. Compared to patients without RHF, mortality was higher in patients with RHF (7.57% vs. 1.11%, p < 0.01). Similarly, acute kidney injury (37.10% vs. 8.56%, p < 0.01), respiratory failure (12.79% vs. 1.91%, p < 0.01), and use of mechanical circulatory support (11.48% vs. 0.83%, p < 0.01) was higher in the cohort with RHF. Median length of stay (7 days vs. 2 days, p < 0.01) and hospitalization charges ($257,239 vs. $180,501, p < 0.01) were higher in patients with RHF. Conclusions: In conclusion, we report that RHF is associated with increased mortality risk, complications, and resource utilization in patients undergoing TAVI. Right ventricular function should be a part of the evaluation for TAVI, given significantly elevated risks associated with its presence. Full article

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of aortic stenosis, particularly in patients at high risk of adverse events for traditional open-heart surgery. Since the early 2000s, TAVR has evolved rapidly with advancements in device technology, procedural techniques, and patient selection criteria. Over the past 20 years, this catheter-based procedure has significantly improved patient survival and quality of life, demonstrating both the safety and efficacy of TAVR, even in patients at low surgical risk. This paper reviews the latest advances in valve design and strategies for treating aortic stenosis. It explores the challenges with long-term outcomes given the younger age of patients undergoing TAVR and the prospects of emerging technologies to improve long-term outcomes. Full article
