This report is filed for the cap separation.It was reported that the dilator and mitraclip steerable guide catheter (sgc) were unable to cross the septum due to the thickness of the septum.Both the dilator and sgc were removed from the anatomy.Balloon dilatation was performed at the septum.After removal from the anatomy, the cap from the dilator rotating hemostatic valve (rhv) was noted to have fallen off.Prior to this, there were no issues with the rhv cap.There were no adverse patient effects from this device issue.A new sgc and dilator were used to complete the procedure without further incident.One mitraclip was implanted reducing the mitral regurgitation from grade 4 to 1.No additional information was provided.
