Revised.
It was reported that the mitraclip procedure was performed to treat mixed mitral regurgitation with grade of 4.
The patient had a small anatomy with small atrium, the septal puncture was a huge problem and the height over the valve was 3.
3 cm.
The steerable guide catheter (sgc) was inserted and advanced into artery, per the instruction for use (ifu).
The physician had to manipulate the clip delivery system (cds) to gain height to the mitral valve; therefore, more curves were applied to the cds than usual and tension was very high.
Before clip deployment, the gripper line broke as due to too much tension.
The procedure was aborted as the second cds would have the same issue.
The cds with the clip attached and gripper line were removed.
There were no clips implanted, mr remained at 4.
There was no adverse patient effect and no clinically significant delay in the procedure.
The cds was returned inside the sgc and analysis revealed that the sgc soft tip was torn.
No additional information was provided.
