Hi. Has anyone experience of the following:
When breathing in, my heartbeat becomes louder, untill it sounds like knocking on my breastbone. It sometimes occurs (lightly) just by sitting up). I'm about 2 weeks post-op.
The cardio has dismissed it as a pericardial rub, but I'm not so sure. To me it sounds like the valve (CE Bovine 27mm) rubbing against the back of my breastbone. If it is (pericardial rub), how long can I expect it to be like this, and does it cause any damage. If not, what else could it be.
