Background: Paravalvular regurgitation (PVR) after transcatheter aortic valve replacement is associated with adverse clinical outcomes. The SAPIEN 3 Ultra (Ultra) is a new generation balloon-expandable transcatheter heart valve with a modified external skirt that is designed to reduce PVR, but reports of clinical and echocardiographic outcomes are limited. The aim of this study was to compare short-term outcomes of patients undergoing transcatheter aortic valve replacement with the Ultra and the original SAPIEN 3 (S3) transcatheter heart valve in a large national registry. Methods: Data from The Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry was used to compare patients who underwent elective, transfemoral transcatheter aortic valve replacement with the Ultra or S3 transcatheter heart valve. Clinical and echocardiographic outcomes were analyzed in a propensity-matched cohort at discharge and 30 days. Results: Patients who underwent transcatheter aortic valve replacement with Ultra (N=1324) from January 2019 to February 2020 were propensity score–matched with patients treated with S3 (N=32 982) during the same period, resulting in 1324 matched pairs. There was no difference in the rate of device success between patients treated with Ultra and S3 (97.1% versus 98.0%, P =0.11). At hospital discharge, PVR was significantly reduced with Ultra compared with S3, with mild PVR in 9.0% versus 13.9% and moderate or greater PVR in 0.1% versus 0.4% (overall P <0.01). At 30 days, there were no differences between Ultra and S3 recipients in the rates of all-cause mortality or stroke (1.8% versus 2.8%, P =0.10), major vascular complications (1.1% versus 1.0%, P =0.84), or permanent pacemaker implantation (6.4% versus 6.2%, P =0.81). Conclusions: In this propensity-matched analysis from the Transcatheter Valve Therapy Registry, the Ultra transcatheter heart valve was associated with similar procedural and 30-day clinical outcomes, but reduced incidence of PVR, compared with S3. The clinical benefit of less PVR should be evaluated in longer-term studies.

AbstractTranscatheter aortic valve replacement has been developed as an emerging technique to treat patients with aortic valve disease. However, safety and outcome data on extremely small transcatheter heart valves (THV) is limited. We aimed to assess hemodynamic profiles and clinical outcome of very small balloon expandable THVs with 20-mm Sapien 3 (SP3).We examined data for all patients who received third-generation SP3 THV at a single hospital. Complications and clinical outcomes were defined based on the VARC-2 criteria. Postoperative prosthesis-patient mismatch (PPM) was defined as indexed effective orifice area (EOA) < 0.85 cm2/m2. We compared clinical characteristics and outcome between patients with 20-mm (n = 21), 23-mm (n = 67), and 26- or 29-mm (n = 113) sized valves.The 20-mm group included significantly higher number of Asian and female populations with lower body surface area. The baseline CT annular area in the 20-mm group was 316.5 ± 24.9 mm2. There was no significant difference between groups in procedural mortality or early safety at 30 days. The higher procedural complication was observed in 20-mm group due to significant differences in minor vascular and bleeding complications. Despite higher post-THV gradients and smaller indexed EOA in 20-mm group, no PPM was observed in 20-mm group. The mortality at 30 days and 1 year in 20-mm group was 4.8% and 16.7%, respectively.The patients who received very small THVs with 20-mm SP3 did not result in PPM and experienced favorable early safety and midterm outcome in our cohort.

Abstract Background A small aortic annulus is associated with increased risk of prosthesis–patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI). Whether specific transcatheter heart valve (THV) designs yield superior hemodynamic performance in these small anatomies remains unclear. Methods Data from 8411 consecutive patients treated with TAVI from May 2012 to April 2019 at four German centers were retrospectively evaluated. A small aortic annulus was defined as multidetector computed tomography-derived annulus area < 400 mm2. TAVI was performed with a balloon-expanding intra-annular (Sapien-3, n = 288), self-expanding intra-annular (Portico, n = 110), self-expanding supra-annular (Evolut, n = 179 and Acurate-Neo, n = 428) and mechanically expanding infra-annular (Lotus, n = 64) THV according to local practice. PPM was defined as indexed effective orifice area ≤ 0.85cm2/m2. Results A small annulus was found in 1069 (12.7%) patients. PPM was detected in 38.3% overall with a higher prevalence after implantation of a balloon-expanding intra-annular or mechanically expanding infra-annular THV compared to self-expanding intra- and supra-annular THV. Multivariable analysis linked self-expanding THV (Evolut: Odds ratio [OR] 0.341, Acurate-Neo: OR 0.436, Portico: OR 0.291), postdilatation (OR 0.648) and age (OR 0.968) to lower rates of PPM, while aortic valve calcification was associated with an increased risk (OR 1.001). Paravalvular regurgitation > mild was more frequent after TAVI with self-expanding THV (p = 0.04). Conclusion In this large contemporary multicenter patient population, a substantial number of patients with a small aortic anatomy were left with PPM after TAVI. Self-expanding supra- and intra-annular THV demonstrated superior hemodynamics in these patients at risk, however at the cost of higher rates of residual paravalvular regurgitation.

The aim of this study was to compare patients with transcatheter aortic valve replacement (TAVR) receiving new generation prostheses SAPIEN 3 (S3, Edwards Lifesc.) and Evolut R (ER, Medtronic Inc.) in terms of periprocedural and long-term outcome. Our retrospective, single-center analysis included 359 consecutive patients with severe aortic stenosis who underwent TAVR with S3 or ER from 2014–2016 (mean age 82 ± 7 years, 47% male, mean EuroSCORE II 8.0 ± 8%, mean follow-up 3.8 years). Device Success was equal (S3 93.0% vs. ER 92.4%, p = 0.812). We report a 30-day mortality of 2.8% in the S3 group, and 2.1% in the ER group (p = 0.674). There was no difference in stroke, conversion to open surgery, vascular and bleeding complications or myocardial infarction. While prosthesis mean gradients were higher with S3 (12.0 mmHg vs. 8.2 mmHg, p < 0.001), there was a trend to less paravalvular regurgitation (PVR moderate or severe: 1% vs. 3.6%, p = 0.088). All-cause mortality up to 5 years did not show a difference (mean survival S3 3.5 ± 0.24 years, ER 3.3 ± 0.29 years, p = 0.895). Independent predictors of long-term mortality were impaired LVEF, chronic kidney injury, peripheral artery disease, malignant tumor and periprocedural stroke. New generation TAVR valves offer an excellent implant and outcome success rate. Long-term survival was independent of prostheses choice and mainly attributed to comorbidities and complications.
