New breast cancer after MX

I had DCIS GRADE3 multiple areas 2008 bilateral mx, opp/hyster 2008. Fast forward Jan 2017 IDC AND ILC HER2 positive ER+ PR-

Had two areas removed yesterday,and two sentinel nodes,one known cancer other we are waiting for path

Breast surgeon stated that there was quite a bit of residual tissue ! My heart had powerful cardiac arrhythmia which put me in distress during first mx. I almost died on the table spent four days in the heart ward than two months had cardiac ablation. Heart is fine now

This appears to be possibly a reason so much was left behind, I clearly am very angry they should've ablated my heart area and then take me back to finish the mx to clear tissue properly but I guess they felt they had done a good job. Which clearly they did not.

I have a call into surgeon this morning to ask whether possibly opening both breasts and making sure all the tissue is removed properly this time or do I just wait do the radiation anti-estrogen and Herceptin?

Has anyone else had this type of complication?

Still waiting on final path

Thank you
