I have tachycardia, mitral valve prolapse, some pvcs. I take dixogin and it controls the rapid heart beat pretty well. My change of insurance meant a new cardiologist. I have seen her a few times for chest pains and she has said there was no cause of concern. A scan of my lungs ordered by another dr indicated anomalous origin of left vertebral artery. He didn't know anything about it so I emailed my new cardiologist. Her response stated it is something I was born with and it isn't dangerous. However, I did find limited information that was cause for concern. Supposedly it is crucial to advise surgeons before any neck surgery or angiogram about this condition and that it can mimic stroke symptoms and actually cause strokes, if I understand the jargon correctly.If this is true, then why didn't the cardiologist say anything? I also am concerned that my elderly mom who has already had two strokes and may at some point need an angiogram has not been diagnosed with this same condition. Should I ask her cardiologist to determine if she has this condition? Can anyone shed some solid information on this? I understand since I have made it this far in life, it may not be a biggie, but I do have a neck vein on the left side that often swells, (ultra-sound normal but swollen vein noted) my head gets numb and last month I had a really bad chest pain while in a meeting that was different. I even wrote a little note to my hubby just in case I dropped. The pain lasted a few days, I was tired and my legs felt funny. I finally went to the cardiologist and she said since I didn't have crushing pain and the feeling of impending doom I was fine. I thought writing a note to my husband meant something as I have never done that. So I left feeling embarrassed. However, I can't help but be concerned as my dad died at age 46 of a heart attack. Oh and I just had a brain scan yesterday, because I had lost the vision in my left eye for about 3 minutes a few months ago. I am wondering if that is related too. thanks for any information anyone can share or if anyone else has this.
