Transcatheter Aortic Valve

Purpose: Left ventricular (LV) mechanics are impaired in patients with severe aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) has become a widespread technique for patients with severe AS considered inoperable or high risk for open surgery. This procedure could have a positive impact in LV mechanics. The aim of the study was to evaluate the effect of TAVR on LV function recovery, as assessed by myocardial deformation parameters, both immediately and in the long term. Methods: One-hundred nineteen consecutive patients (81.2 ± 6.9 years, 50.4% female) from 10 centres in Europe with severe AS who successfully underwent TAVR with either a self-expanding CoreValve (Medtronic, Minneapolis, MN, USA) or a mechanically expanded Lotus valve (Boston Scientific, Natick, MA, USA) were enrolled in a prospective observational study. A complete echocardiographic examination was performed prior to device implantation, before discharge and 1 year after the procedure, including the assessment of LV strain using standard 2D images. Results: Between baseline and discharge, only a modest but statistically significant improvement in GLS (global longitudinal strain) could be seen (GLS% –14.6 ± 5.0 at baseline; –15.7 ± 5.1 at discharge, p = 0.0116), although restricted to patients in the CoreValve group; 1 year after the procedure, a greater improvement in GLS was observed (GLS% –17.1 ± 4.9, p < 0.001), both in the CoreValve and the Lotus groups. Conclusions: Immediate and sustained improvement in GLS was appreciated after the TAVR procedure. Whether this finding continues to be noted in a more prolonged follow-up and its clinical implications need to be assessed in further studies.
