Abstract:
Paravalvular leak (PVL), conduction disturbances, and vascular complications remain the most common complications after TAVR. To address these adverse outcomes, the third generation of transcatheter heart valves has been developed. The last generation prosthesis provides an outer pericardial wrap for enhanced sealing and PVL prevention. This study aimed to compare the incidence and severity of PVL and 1-year survival after TAVR using SAPIEN 3 with those using EVOLUT PRO. An observational retrospective analysis was conducted in 1,481 patients who underwent TAVR for symptomatic severe aortic stenosis in 6 different European centers. The primary end point was to assess the frequency and severity of PVL at 30 days after TAVR. The secondary end point was to compare 1-year survival using EVOLUT PRO with that using SAPIEN 3. SAPIEN 3 transcatheter heart valve was implanted in 78.3% of study participants (n = 1,160) whereas EVOLUT PRO was implanted in 21.7% (n = 321). PVL is more commonly observed in patients treated with EVOLUT PRO at prehospital discharge (55.1% vs 37.3%) and at 1-month (51% vs 41.4%) and 1-year (51.3% vs 39.3%) follow-up. This difference mainly concerns low-grade (mild/trace) PVL. The frequency of high-degree (moderate/severe) PVL was almost similar in both groups throughout the study period (5.3% vs 5.8% before hospital discharge, 4% vs 3.1% at 1 month, and 3.2% vs 4.9% at 1 year). No significant difference in survival over 1 year has been observed (hazard ratio 0.73 [0.33 to 1.63], p = 0.442) (Graphical abstract). In conclusion, the detection rate of PVL after TAVR with third-generation heart valves remains high, and there are no major differences between the devices regarding the frequency of significant (moderate/severe) PVL and survival.
