5 weeks after the COVID 19 vaccine, while on Title 10, I was diagnosed with possible inflammation in my heart, a leaking bicuspid aortic valve, and a severe ascending aortic aneurysm. 6 months later I was in open heart surgery to repair the aneurysm and replace the aortic valve with a mechanical valve. Roughly 9 months later I suffered a stroke due to a clot forming on the valve. Luckily there were not any lasting detriments. An LOD was initiated at my unit and after months of waiting I was notified yesterday that the condition was ruled “Not in the line of duty” because the bicuspid valve was congenital and 50% of people born with it end up with an aneurysm. I have 30 days to appeal the determination. I am heartbroken over this decision. If my congenital valve was 75-80% likely to cause an aneurysm I could maybe understand. But 50% means it was just as likely to not happen and makes me feel like the military is choosing to turn against me without a legitimate preponderance of evidence. I did not know I had a bicuspid valve and was completely asymptomatic of any issue until hours after the 2nd round of the COVID vaccine. I’m getting no guidance on how to appeal this decision. Don’t even know who the appeal goes to. My Unit is telling me if it doesn’t get overturned I will most likely be non-retained when my enlistment is up (February 2025) because I’m on an anticoagulant indefinitely and non-deployable, be forced into a normal retirement, not be able to draw my retirement until 57 and not get Tricare. I will have a litany of medical appointments and medications for the rest of my life. The thought of losing Tricare is unbearable. I owe everything to my 23 years in the military but after this decision I am regretting every second of it. I’m looking for any and every resource to help me complete this appeal. All help is greatly appreciated!!
