b. Occurrence of moderate or severe PPM
At one-month FU, echo data were available for 143 patients (97 for the TAVR group, 46 for the RDAVR group). LVEF was 61.33±9.09% in RDAVR group and 60.39±13.67% in TAVR group(p=0.67). Indexed EOA was 1.02±0.28cm²/m² in the RDAVR group and 0.97±0.23cm²/m² in the TAVR group(p=0.31). Mean gradient was 10.33±3.42mmHg in the RDAVR group and 12.84±3.81mmHg in the TAVR group (p<0.001). The rate of Mitral regurgitation (MR) ≥ grade 2 was 11.54% in TAVR group in 2.22% in RDAVR group (p=0.14). Systolic pulmonary artery pressure (sPAP) was 33.53±9.40mmHg in RDAVR group and 41.52±14.28mmHg in TAVR group (p=0.009). Fifteen patients (32.61%) had PPM in RDAVR group, including 13 moderate PPM (86.66%) and 2 severe PPM (13.34%). Seventeen patients (36.96%) had PPM in TAVR group, including 15 moderate PPM(88.23%) and 2 severe PPM(11.77%). By propensity score matching analysis, the rate of moderate/severe PPM was similar between both groups (HR=0.83[95%CI: 0.35,1.94],p=0.66).
