We read with great interest the article by Rottländer et al entitled “CT-Angiographic imaging of the Carillon device topography after unsuccessful treatment of FMR”1, suggesting that parameters such as coronary sinus (CS) to mitral valve annulus distance and angle might predict response to Carillon device implantation. However, the measurements were obtained nine months following the procedure when they might not reflect native preprocedural anatomical relationships. The Carillon device applies tension on the vein and frequently alters relations between adjacent structures. As an example, the vein can be displaced by the device which causes the artery ...
