N2 - Aim The impact of paravalvular regurgitation (PVR) following transcatheter aortic valve replacement (TAVR) remains uncertain. In this analysis, we sought to evaluate the impact of varying degrees of PVR on both mortality and changes in ventricular geometry and function. Methods and results Clinical and echocardiographic outcomes of patientswhounderwentTAVRfromthe randomized cohorts and continued access registries in the PARTNERtrialwere analysed after stratifying by severity of post-implant PVR, whichwas graded as none/trace in 52.9% (n = 1288), mild in 38.0% (n = 925), and moderate/severe in 9.1% (n = 221). Therewere significant differences in baseline clinical and echocardiographic characteristics. After TAVR, all the patients demonstrated increase in left ventricular (LV) function and reduction in the LV mass index, although the magnitude of mass regressionwas lower in the moderate/severe PVR group. The 30-day mortality (3.1 vs. 3.4 vs. 4.5%, P = 0.56) and stroke (3.4 vs. 3.7 vs. 2.3%, P = 0.59)were similar in all groups (none/trace, mild, andmoderate/severe). At 1 year, therewas increased all-cause mortality (15.9 vs. 22.2 vs. 35.1%, P < 0.0001), cardiac mortality (6.1 vs. 7.4% vs. 16.3%, P < 0.0001) and re-hospitalization (14.4 vs. 23.0 vs. 31.3%, P < 0.0001) with worsening PVR. A multivariable analysis indicated that the presence of moderate/severe PVR (HR: 2.18, 95% CI: 1.57-3.02, P < 0.0001) or mild PVR (HR: 1.37, 95% CI: 1.14-1.90, P = 0.012) was associated with higher late mortality. Conclusion Differences in baseline characteristics in patients with increasing severities of PVR may increase the risk of this complication. Despite these differences, multivariable analysis demonstrated that both mild andmoderate/severePVRpredicted higher 1-year mortality.
