Comparing the Procedural and Clinical Outcomes of Sapien XT and Sapien 3 Valves in Transcatheter Aortic Valve Replacement in Korean Patients.

ABSTRACT: BACKGROUND AND OBJECTIVES:The Sapien 3 (S3) valve has not been compared to the Sapien XT (SXT) valve in Korea. We compared procedural and clinical outcomes between the 2 devices. METHODS:A total of 189 patients who underwent transcatheter aortic valve replacement (TAVR) with S3 (n=95) or SXT (n=94) valve was analyzed. The primary endpoint was cardiovascular mortality at 1 year. The median follow-up duration was 438 days. RESULTS:The Society of Thoracic Surgeons score was similar between the 2 groups. The device success rate (90.4% vs. 97.9%; p=0.028) was higher in the S3 than in the SXT. The S3 showed significantly fewer cases of moderate or severe paravalvular leakage (PVL) (16.7% vs. 0.0%; p=0.001) than the SXT. However, effective orifice area (EOA) (2.07±0.61 vs. 1.70±0.49 cm²; p<0.001) was smaller in the S3. Multivariable Cox regression analysis showed the S3 was associated with significantly fewer cardiovascular mortality at 1 year compared to the SXT (5.4% vs. 1.1%; hazard ratio, 0.031; 95% confidence interval, 0.001-0.951; p=0.047). Periprocedural complication rates, composite of disabling stroke or all-cause mortality, all-cause mortality, and disabling stroke at 1 year were similar between the 2 groups. CONCLUSIONS:Cardiovascular mortality was lower in the S3 group than in the SXT group over 1 year of follow-up. The reduction in PVL was attributed to the higher device success rate of TAVR with the S3 valve. However, the benefit of S3 obtained at the expense of reduced EOA should be meticulously re-evaluated in larger studies during long-term follow-up.

Project description:Background: Valve-in-Valve transcatheter aortic valve implantation (ViV-TAVI) is a growing alternative for redo-surgery in patients with degenerated surgical valves. To our knowledge, data are lacking on the determinants on ViV-TAVI procedural success in patients with degenerated surgical valves. Methods: All consecutive patients undergoing ViV-TAVI for degenerated surgical valves at the Cleveland Clinic were analyzed. Data were extracted from our patient registry on baseline patient characteristics, echocardiographic parameters, and procedural details. To identify possible predictors of ViV-TAVI procedural success, we employed a multivariate logistic regression model. Results: A total of 186 patients who underwent ViV-TAVI were analyzed, with procedural success (VARC-2 device success and absence of periprocedural MACCE) reported in 165 (88.7%) patients. Patients with successful ViV-TAVI were significantly younger and had more frequent utilization of the transfemoral access than those with failed procedure. Other baseline and procedural characteristics were comparable between both groups. In terms of echocardiographic parameters, the procedural success group had a significantly lower AV peak pressure gradient (62.1 ± 24.7 vs. 74.1 ± 34.6 mmHg; p = 0.04) and lower incidence of moderate-to-severe aortic regurgitation [AR] (30.4 vs. 55%; p = 0.04). However, no significant differences between both groups were noted in terms of AV mean pressure gradient and left ventricular measurements. In multivariate analysis, lower AV peak pressure gradient (OR = 0.97, 95% CI: 0.95-0.99) and absence of moderate-to-severe AR (OR = 0.65, 95% CI: 0.44-0.95) at baseline emerged as independent predictors of ViV-TAVI procedural success. Conclusion: Valve-in-Valve TAVI for degenerated surgical valves is a feasible approach with high success rates, especially in those with lower AV peak pressure gradient and absence of moderate-to-severe AR. Studies with larger sample size and longer follow-up are required to further characterize the predictors of ViV-TAVI success and other clinical outcomes.

Project description:Importance:Moderate/severe and even mild paravalvular regurgitation (PVR) are associated with increased mortality following transcatheter aortic valve replacement (TAVR) with first and second generations of transcatheter valves. Objective:To examine the incidence, evolution, and effect on 1-year outcomes of PVR following TAVR with a third-generation balloon-expandable transcatheter heart valve. Design, Setting, and Participants:Prespecified analysis of PVR in the Placement of Aortic Transcatheter Valves (PARTNER) II SAPIEN 3 trial, conducted between October 1, 2013, and September 3, 2014. Multicenter, nonrandomized registry of 1661 patients at intermediate or high surgical risk undergoing TAVR with the SAPIEN 3. Patients with severe, symptomatic aortic stenosis and high/intermediate surgical risk were enrolled in the registry at 51 sites in the United States and Canada. Interventions:Transcatheter aortic valve replacement with the SAPIEN 3 valve. Main Outcomes and Measures:Paravalvular regurgitation was assessed in a core laboratory at 30 days and 1 year according to a 5-class scheme: 0, none or trace; 1, mild; 2, mild to moderate; 3, moderate; 4, moderate to severe; and 5, severe. We assessed the effect of PVR on 1-year mortality and heart failure rehospitalization. Results:Among the 1661 included in the registry, 1592 received a SAPIEN 3 valve and had assessment of PVR. Of these patients, 55.7% had none-trace PVR, 32.6% had mild, 8.2% had mild to moderate, and 3.5% had at least moderate PVR at 30 days. At 1 year, 9.3% of patients had died and 14.2% had been rehospitalized. Only patients with at least moderate PVR had higher 1-year mortality (hazard ratio [HR], 2.40; 95% CI, 1.30-4.43; P?=?.005) and composite of mortality/rehospitalization (HR, 2.35; 95% CI, 1.52-3.62; P?<?.001). In a paired comparison including 1213 patients, 73% of the patients with at least moderate PVR at 30 days showed a reduction in PVR severity of at least 1 PVR class at 1 year. Conclusions and Relevance:In this series of patients undergoing TAVR with the SAPIEN 3 valve, at least moderate PVR was rare but associated with increased risk of death and heart failure rehospitalization at 1 year. Even the upper range of the mild class in the 3-class grading scheme (ie, mild to moderate in the 5-class scheme) had no significant effect on short-term mortality or rehospitalization. Most patients with at least moderate PVR at 30 days showed a decrease of PVR severity grade at 1 year. Trial Registration:clinicaltrials.gov Identifier: NCT01314313.
