Association of Paravalvular Regurgitation With 1-Year Outcomes After Transcatheter Aortic Valve Replacement With the SAPIEN 3 Valve. - 2017

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. 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. 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. 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. 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. 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.
