The effect of balloon-expandable stent and self-expanding stent on changes in mitral annular motion after aortic valve replacement in patients with aortic stenosis.
Objectives: The purpose of this study was to evaluate the effect of decalcification and existence of stent at the aortic annulus on mitral annular motion after surgery.
Methods: Patients receiving Inspiris (Edwards, CA, USA, n = 117), Intuity (Edwards, n = 36), Perceval (Corcym, London, UK, n = 36), Evolut (Medtronics, MN, USA, n = 81) and Sapien 3 (Edwards, n = 250) were included in the study. Mitral annular motion was evaluated by E', using tissue doppler imaging.
Results: After surgery, a significant increase in E' was observed in patients receiving Inspiris (Before: 4.2 ± 1.21 cm/s vs. Discharge: 5.0 ± 1.23 cm/s, p < 0.001). Mid-term echocardiogram performed at 11.8 ± 2.2 months after the surgery, showed a significant increase in E' in patients receiving Inspiris (Before: 4.2 ± 1.21 cm/s vs. Mid-term: 5.2 ± 1.20 cm/s, p < 0.001) and Perceval (Before: 3.9 ± 1.34 cm/s vs. Mid-term: 4.5 ± 1.24 cm/s, p = 0.008). Univariable analysis showed a higher increase in E' in patients with decalcified annulus compared to those without decalcified annulus (Decalcification: 0.15 ± 1.321 cm/s vs. No Decalcification: 0.66 ± 1.420 cm/s, p < 0.001). Multivariable analysis showed that balloon-expandable stent (β = - 0.6960, p < 0.001) and self-expanding stent (r = - 0.3592, p = 0.042) were independent limiting factors for an increase in E' at discharge. However, balloon-expandable stent (β = - 0.8382, p < 0.001), and not self-expanding stent (β = - 0.3682, p = 0.089), was a remaining independent factor associated with E' at mid-term follow-up.
Conclusions: Decalcification was associated with improvement in E' after surgery. Balloon-expandable stent was an independent limiting factor for improvement in E' up to 1 year after the surgery, while self-expanding stent was not a significant factor after 1 year.
期刊介绍:
The aim of the Journal of Artificial Organs is to introduce to colleagues worldwide a broad spectrum of important new achievements in the field of artificial organs, ranging from fundamental research to clinical applications. The scope of the Journal of Artificial Organs encompasses but is not restricted to blood purification, cardiovascular intervention, biomaterials, and artificial metabolic organs. Additionally, the journal will cover technical and industrial innovations. Membership in the Japanese Society for Artificial Organs is not a prerequisite for submission.
