heart problems during pregnancy

Nadia
Hi all long story short I have a pacemaker and have done since age 6, had open heart surgery at that time and dextracardia which means my heart is other way around as in other side not upside down. Anyway I was wondering if anyone has gone through pregnancy with a heart issue or intact pacemaker/defibrillator? I have an old one still in my stomach that they neve took out so I presume that will need to be removed also. Thanks in advance xx
