My mom is 70 and she had an Amplatzer device placed in her heart two weeks ago to close an ASD. She is recovering but is feeling very tired, and had a couple of small episodes of tachycardia yesterday. When she is at rest, sitting or in bed, she is okay, but today she walked on the street not even a block and felt very tired. We came back and everything is apparently fine again. Can someone share his or her experience with the implant? She has an appointment with the doctor soon, but I might have to ask him to see her before. Please share your experience!
