RESULTS: The prospective, single-arm, multicentre REPRISE II study with extended cohort enrolled 250 symptomatic, high surgical risk patients with severe aortic stenosis for transfemoral transcatheter aortic valve implantation (TAVI) with a 23 mm or 27 mm LOTUS valve. Echocardiography, computed tomography, and electrocardiography data were evaluated by independent core labs. Post TAVI, 32.0% (72/225) of pacemaker-naïve patients underwent new PPM implantation at 30 days. Most (59/72, 82%) patients were implanted for third-degree atrioventricular block, and >10% overstretch of the LVOT by area was observed in 59.7% (43/72) of PPM patients. Significant independent predictors of PPM at 30 days included baseline RBBB (odds ratio [OR] 12.7, 95% CI: 4.5, 36.2; p<0.001) and LVOT overstretch >10% (OR 3.4, 95% CI: 1.7, 6.7; p<0.001). There was a trend towards a lower 30-day PPM rate in patients with a shallower (≤5 mm) implant depth (23.9% ≤5 mm vs. 36.9% >5 mm depth from LCS; p=0.06). CONCLUSIONS: Careful attention to valve sizing and implant depth may help to reduce the rate of PPM with the LOTUS valve.Show less >
