I survived a complete aortic dissection in 2015. I was 50 years old. My best advice to you is to make sure that your husband does everything he can to reduce his blood pressure and to relax. Listen to your medical team. You’ve already got what sounds to be like experts working your case and they will tell you what needs to happen next. It’s super important that you listen and you follow their advice. A spontaneous dissection is often not survivable without immediate intervention in the form of open heart surgery. You’re in the right place and you’re doing all the right things. Just keep all your appointments and talk with your doctors. Advocate for your husband and make sure that all of his affairs are in order in terms of healthcare directives, living Will, powers of attorney, and his last one, the Testament if he hasn’t done one. It will bring him a lot of peace and bring you a lot of peace as well so that you’re not guessing at what happens next in the event he goes in the surgery. You’re gonna be OK. Just listen to your doctors. Peace.
