This is filed to report atrial perforation and medical intervention.
It was reported that this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 4.
It was noted a pre-existing atrial septal defect (asd).
The steerable guide catheter (sgc) was advancing to the mitral valve; however, wire access was lost twice and the transseptal puncture had to be re-performed two additional times.
The sgc was advanced to the mitral valve, and one clip was deployed.
The physician closed the septum with a transseptal plug due to the pre-existing asd that the sgc possibly worsened.
One clip was implanted, reducing mr to 2.
There was no clinically significant delay in the procedure.
No additional information was provided.
