Non Healing Pacemaker Wound
I wonder if anyone ever had any experience with their pacemaker wound taking an extremely long period of time to close up and heal.
I had my first pacemaker implanted when I was 10 years due to frequent syncopal attack after which I diagnosed with complete heart block. I had VSD repair when I was 4 years old which the cardiologist is likely a complication following the initial open heart surgery. Fast forward, I am 30 years old now with no regular medications and no other medical conditions. I had my 2nd box change around 6 months ago. As it is the 3rd time, the same site is being cut, I have developed mild to moderate scar tissue as evident by keloid tissue over my skin. The 2nd box change took around 4 months to heal and there's still 2x2cm open wound which is just not granulating. Given the case, my cardiologist thinks it is likely to due to poor healing of the overlying scar tissue.
So the cardiologist decided to do a wound revision surgery to excise all the scar tissue and bring the healthy skin margins together. I have had the wound revision surgery done about 4 weeks ago. Again the same area where there was a gaping wound is healing significantly slower compared to the rest of the wound.
Has anyone who had multiple box changed in the past experienced similar issues? I am extremely concerned if there's any underlying collections underneath the wound (not visible to naked eye) that might be causing such poor wound healing?
