My son-in-law at 50 last summer, was diagnosed with a 4,9 AAA AND a ‘healthy’ bicuspid valve. He is VERY healthy, lifts weights, avid hiker and skier. All bloodwork and BP normal. Longevity in fam(dad 88 and mom 90.) The drs did not want to take a chance since he wants to keep his exercise regime. So tomorrow, he has the open heart surgery to repair the root. Will be on the heart/lung machine for a 5/6 hr surgery. Praying that they don’t accidentally damage his apparently healthy bicuspid valve. Out come is supposed to be very positive. I lost my husband(54) 30 years back to the dissection of the aorta. You and my son-in-law are fortunate you’ve been diagnosed early. Good luck to you and wish you the best outcome!
