RIP to kentaro Miura he died from this, truly heartbreaking
came here for the same reason :(
Never seen it comming blindsided me it's a tragicty
A cruel and inglorious end.
Wow. I’m not in the medical field at all. I’m just a nerd who likes this stuff and even I understood that. Great presentation. Thanks.
My dad died from aortic dissection 3 months ago. His was the type A ascending. He died pretty much instantly. He was 59. Medics worked him for 45 minutes. This video really helped me understand what happened. He had high blood pressure.
I'm so sorry for your loss
I'm so sorry for your loss In Sha Allah may he rest in peace Ameen
Rest in peace 😔💕
My sister died same way. She was 51 years old and 100 days and I am about 50 and a half right now. I always thinking I might die so I had the echocardiogram two times, once in 2014 and after my sister passed in 2021. The radiologist said my aorta is perfect! It's so scary though.
@@reginafelizardo987 So sorry to hear about your sister. 51 seems so young, how tragic. Did she have any symptoms? Was she on any medications?
My dad was just diagnosed with this, age 64, and doctors are "keeping an eye on it". They don't think it's a recent development, although that doesn't make us feel much better.
He has no symptoms, so it's pretty scary knowing it could rupture at any time without warning.
He wants to ask about genetic testing to see if my siblings & I are at risk for developing something similar. Did your sister have any childrenm
Mash'Allah and Suban'Allah that was explained beautifully brother
an incredibly well put together and well timed video . thank you for the amazing teaching

This is very helpful.
Well done Sir! Excellent presentation!
mostly accurate, good video
thank you , very helpful
Great explanation. Well done.
I just had open heart surgery for ascending aortic tear. It’s been an ordeal so far! It’s nice to have this excellent and detailed information 7 days out. Thank you!
How are you feeling 1 year later? Hope your recovery went well!
Solid work!!
Your perfect explanation 🥺❤️
Absolutely beautiful presentation. Just lost a friend to dissection of aorta ..so I wanted to know more.. so sad 😞
What did you use for the well put together presentation? A phone? Software? Etc…?
Thank you! I have a Type A dissection. It's nice to have it explained in simple layman terms.
Get well soon
useful video.. thank u so muh
*much
I had a Type B Aortic Dissection about four years ago and the pain was the worst I've ever had to endure (aged 48 at the time). Treated with a stent. Mine began high up on the ascending Aorta and went all the way down to where the Aorta branches off into my legs.
This was a great explanation of what goes on.
Regarding the initial pain, it can happen in reverse, I first felt pain in the back which then moved towards my chest rather than as described in the video.
Mine started right at the top of the ascending Aorta and went down almost to my legs. The actual hole between the inner and middle layers is 4.5cm but the channel between the layers tunneled from the top down to my legs. Stenting is the preferred treatment with Type B dissections, whereas Type A requires surgery.
Any comments on what causes it?
In my case I had two things against me. The first being High Blood Pressure! The second is that dissections run in my family. An Aortic Dissection killed my Grandfather and Father. So, they can run in families but my biggest issue was my Blood Pressure.
Sorry to hear that! Thanks for the answer. I hope all is well with you and take care!
I suffered an Aortic Dissection in 2015 aged just 21. I didn't drink, smoke or touch drugs. Exercised regularly and was a healthy weight.
Suffered palpitations in the night when asleep several times before my actual dissection. The night it happened, woke up, collapsed with the pain. Was rushed into hospital and underwent heart surgery to save my life. Touch and go whether I pulled through but I managed.
Every day is a gift.
Thank You Gore Medical

Holy moly I didn’t realize the aorta was so long!!! OMG
Me either
Do you have further study or video that discuss this same case with pregnant women?
What do they do if you're allergic to CT contrast dye? I ask because I'm allergic to it.
Thank you for the video, where is the ascending aorta located?
I suffered a (AAA,) Stanford Tybe B aortic dissection and never fully understood what it was until your excellent review which explained the differences really well. If you see my message. "What is the long term diagnosis" I have CT scans once a year and meet with my thoracic surgeon. Bottom line, can I expect to live many more years, Im 58 now, and had the surgery 6 yrs ago.
YES
How is there less risk to the patient with a CT as opposed to MRI?
I have 44 years old. I had a Debakey Type 1 aortic dissection 6 months ago. The lesion extended from the beginning of the ascending aorta to the middle of the left leg. Aortic reconstruction surgery was performed with a high-quality Dacron tube. The surgery was a success. Currently I feel very well, I can do practically any physical activity, but I have to take medication to control blood pressure daily. My concern is that I read an article in the MSD Manuals where in patients treated surgically, the survival rate is about 60% at 5 years and 40% at 10 years, that is, I have little time to live. Is it possible to survive longer than that? I´m trying my best. Thanks
My father died after the double open surgeries of abdominal aortic aneurysm and bypass
Rip miura
I don't get the final part. How come he says that the CT is the gold-standard because it carries less risk than the MRI? They are both non-invasive, how can the MRI be risky?
Maybe with injecting the contrast dye?
it's 5 am. the egg analogy made me hungry
MRI has less risks actually than CT, but its just more expensive and takes more time than CT.
I have chronic HBP, a day before seeing this video my reading was 207/101 then i began feelin a sharp tearing pain in my back above the right kidney. Im concern
You need to control your diet. No refined sugar and salt is acceptable. Your bp will drastically go down if you change your diet, drink a lot of water, and exercise.
One of our patients died from aortic dissection. Actually he succumbed to cardiac tamponade but that condition occurred because he had aortic dissection. He also had an AAA at the abdominal level but he died from the cardiac tamponade.
Does anyone know what app is he using?
Myspace
My husband now has stroke. He suddenly fainted during his sleep on 31/12/2020. He has hypertension. End up with left basal ganglia bleed with global aphasia and right hemiplegia, ckd stage 3, and currently diagnosed with Stanford type b type 3 aortic desection - thanks for the explanation about aortic desection. I can understand the whole concept about aortic. I am normilah from malaysia. I am here because I want to know n. Understand better about this.
Diet control, exercise, and pomegranate juice can help a lot.
Please i have a aaa and due surgery open surgery will i be ok after operation if i go ahead i am 69 years old please please advise me
If you have good surgeon and also maintaining a healthy diet and getting exercise will help tremendously. I survived it 14 years now.
How did it go??
RIP. John Ritter he died from that very same thing
What is the difference between aortic dissection and aortic aneurysm
A dissection is where two layers of the vascular wall is separated (the loose part of the wall can disrupt normal blood flow (and maybe cause statis(?) which would become a perfect place for thrombosis)). An aneurysm is when a vascular wall becomes thinner (and thus more likely to rupture).
Difference betweenaortic dissection and aortic aneurysm
10:43 is that one of the reasons why we die of old age?
Everything in our bodies gets more and more weakened with time. That’s life. It’s not only our blood vessel’s walls that get old and weak, but pretty much everything inside of us, from our immune system to our DNA repair system, just to name a few. That’s why a lot of old people die from infections or cancer. But Aortic Dissections are still rare among healthy elderly, because you need high blood pressure to tear up the inner wall of arteries. That’s why patients with hypertension are at higher risk of developing it.
13:30 "CT is still the gold standard because it comes with less risks to the patient (than MRA).
Sorry, I don't know much about this field, but from reading around, I thought CT scan is usually less preferred because it uses radiation (side effects of cancer, nausea), whereas MRI has no known side effect. What do you mean by MRA having more risk than CT scan?
Although CT does use radiation and iodinated contrast (potential for allergies and AKF), the MRA scan itself takes a considerable amount of time and is contraindicated in patients with metal implants that are non-MRI compatible. You can imagine that a patient who does have a dissection and is quite ill would most likely not be able to stay still for a long duration scan and also won't be able to receive direct medical treatment. Comparatively, CT is much faster and for the most part more widely available. The radiation issue only really raises concern in patients that are pregnant or at a radiosensitive age eg. kids
What is Unfolding Thoracic Aorta?i had my x ray and my lungs is clear, hila and medistanum is unremarkable heart is normal with unfolding thoracic aorta...that is my xray comment....
