Abstract
BACKGROUND The Navitor (Abbott Inc, IL, USA) transcatheter heart valve is a novel third-generation self-expanding bioprosthesis with specific features to mitigate paravalvular regurgitation (PVR). Owing to its novelty, there is a paucity of data on its application in clinical practice. METHODS Consecutive cohort analysis of the use of the Navitor system in an as-treated clinical setting at a quaternary heart hospital. RESULTS Sixty consecutive non-clinical trial patients treated with Navitor were identified. All patients underwent a successful procedure. The mean age was 79.3 years (±SD 7.82), 56.67% (n=34) were female, and the mean STS score was 4.87 (±SD 5.70). At 30 days post-procedure, all patients were alive with no readmissions for heart failure. One patient had a major vascular complication (1.7%). Four patients (7.14% of patients without a pre-existing pacemaker) received a new permanent pacemaker. Two patients (3.4%) had a non-disabling stroke. PVR at 30 days was trivial or none in 75% of patients, and no patient had worse than mild PVR. CONCLUSIONS The Navitor system in this as-treated cohort was associated with favourable clinical, haemodynamic, and safety outcomes.

Abstract
The purpose of this first-in-human (FIH) study was to determine the safety and feasibility of the transfemoral premounted dry-pericardium Vienna Self-Expandable Supra-Annular Aortic Valve System. This novel system is repositionable and retrievable and comes already premounted on the delivery system, eliminating the need for assembly and crimping of the device before valve implantation. This is a prospective, nonrandomized, single-arm, single-center, first-stage FIH feasibility study, which will be followed by a second-stage pivotal, multicenter, multinational study in symptomatic patients with severe aortic stenosis. The first-stage FIH study evaluated the safety and feasibility of the device in 10 patients with severe aortic stenosis based on recommendations by the Valve Academic Research Consortium-2 for transcatheter aortic valve implantations. The mean patient age was 79 ± 5 years, 60% were male, and all patients were in New York Heart Association functional class II to III. The primary safety end point was successful when all patients were alive at 30-day follow-up. Device and technical success were observed in all patients. Two patients had a stroke, 1 of which occurred 5 days after the procedure. New permanent pacemakers were implanted in 2 patients (22.2%), of which only 1 was because of complete heart block. Only 1 patient (10%) had moderate paravalvular leak at 30 days. After the procedure, the mean aortic valve gradient decreased from 48.7 ± 10.8 mm Hg to 8.8 ± 4.3 mm Hg. In conclusion, this FIH feasibility study demonstrates successful procedural feasibility, with no 30-day mortality and favorable valve hemodynamic performance, leading to an improvement in quality of life.

Abstract
Transcatheter aortic valve replacement (TAVR) is an established therapy for severe, symptomatic aortic valve stenosis even in patients with impaired left ventricular systolic function. However, there is uncertainty on the clinical effectiveness of the currently available TAVR devices in patients with reduced left ventricular ejection fraction (LVEF). The LOSTAVI (Low Systolic function and Transcatheter Aortic Valve Implantation) registry is a retrospective observational study using baseline, procedural, discharge, and long-term follow-up details. A total of 3 groups of interest were distinguished: extremely reduced LVEF (<25%), severely reduced LVEF (25% to 30%), and reduced LVEF (31% to 35%). Unadjusted and adjusted analyses were carried out for in-hospital and follow-up outcomes. A total of 923 patients were included from 12 centers, with 146 patients (16%) with LVEF <25%, 425 (46%) with LVEF 25% to 30%, and 352 (38%) with LVEF 31% to 35%. Several baseline and procedural features were different across groups, including age, risk, functional class, and prevalence of bicuspid disease (all p <0.05). In-hospital mortality was similar in the 3 groups (7 [4.8%], 18 [4.2%], and 7 [2.0%], respectively, p = 0.661), but major adverse events were more common in those with extremely reduced and severely reduced LVEF (19 [13%], 53 [13%], and 25 [7.1%], respectively, p = 0.024). The 12-month follow-up confirmed the significant detrimental impact of reduced LVEF on both death (21 [14%], 49 [12%], and 25 [7.1%], respectively, p = 0.024) and major adverse events (37 [25%], 89 [21%], and 53 [15%], respectively, p = 0.016). The adjusted analysis confirmed the significant prognostic role of LVEF on both outcomes, whereas TAVR device type was not associated with death or major adverse events (all p >0.05). In conclusion, TAVR yields favorable early and 1-year results in patients with reduced LVEF, including those with extremely depressed systolic dysfunction. However, reduced LVEF still represents a major adverse prognostic factor for both short- and mid-term outcomes.

Abstract
Transcatheter aortic valve implantation (TAVI) has risen over the past 20 years as a safe and effective alternative to surgical aortic valve replacement for treatment of severe aortic stenosis, and is now a well-established and recommended treatment option in suitable patients irrespective of predicted risk of mortality after surgery. Studies of numerous devices, either newly developed or reiterations of previous prostheses, have been accruing. We hereby review TAVI devices, with a focus on commercially available options, and aim to present a guide for prosthesis tailoring according to patient-related anatomical and clinical factors that may favor particular designs.
