ABSTRACT
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 (ß = - 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 (ß = - 0.8382, p < 0.001), and not self-expanding stent (ß = - 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.Palavras-chave
