AIMS: Limited information exists describing the results of transcatheter aortic valve replacement (TAVR) in patients with symptomatic severe non-calcific aortic stenosis (AS). We aimed to compare procedural, echocardiographic, and clinical outcomes among patients with non-calcific AS with those of senile calcific AS undergoing TAVR.
METHODS AND RESULTS: We retrospectively identified patients with non-calcific AS who received TAVR with self-expanding transcatheter heart valves in our centre. Clinical and echocardiographic outcomes, and post-procedural multi-detector computed tomography (MDCT) measures were compared to those in patients undergoing TAVR for calcific AS. Among 136 patients, 21 patients (15.4%) with native leaflet thickening and minimal calcification were identified (non-calcific group). The patients were significantly younger in the non-calcific group (70.0 [64.0-75.5] vs. 75.0 [69.0-78.0] years) with comparable STS-PROM scores (6.7 [4.8-8.9] vs. 8.2 [4.8-10.9] %). Predilation was performed less frequently (42.9% vs. 93.9%) and post-dilation more often (71.4% vs. 42.6%) in the non-calcific group. Both 30-day and one-year mortality were similar between groups (0% vs. 7.8% and 0% vs. 17.6%). Rates of post-implantation paravalvular leak ≥mild at six months (17.6% vs. 25.7%) were comparable despite lower implantation depth among non-calcific AS patients (10.9±5.7 vs. 7.2±4.3 mm) on post-implantation MDCT.
CONCLUSIONS: TAVR with self-expanding transcatheter heart valves appears to be safe and effective in patients with non-calcific AS.
