I'm 51 years old and had OHS 13 weeks ago. The purpose of the surgery was to repair an atrial aortic aneurysm and a leaky valve. I opted for the mechanical valve. My recovery is going well with the exception of Petechiae on the lower 8 inches of my legs (ankle and above). The Petechiae appeared about 3 weeks ago. It isn't painful, but feels like a minor sunburn. I'm in cardiac rehab 3 times per week and walk about 2 miles per day. I'm certain the Petechiae is associated to the Warfarin. I'm curious to hear from others who may have experienced this condition. Did it go away? Does exercise worsen the Petechiae? Finally, I read elsewhere that a person's Petechiae vanished after they switched from Warfarin to Coumadin. Thank you.
