I was having so much anxiety after recently diagnosed with aortic stenosis. However, after watching your video it was clear what option I'll use if it gets worse. Thank you very much.

I was diagnosed today with Aortic Stenosis "(severe)"... and suddenly I'm tongue tied. I guess it hasn't settled yet. Anyway, it was all explained to me in great detail by competent doctors and I barely recall anything said. It's now 3am and I'm at the point of I'll fight and whip this ASS. At least if it can be I will - so it's probably a good idea to do a crash course on AS-Severe. Logically that means hello KZfaq! This lecture is it so far. Ive got a good overview and do get there will be a lot of fine detail to go but this was exactly what I needed. Right here, right now. Many thanks! Got to run Tony (Public health advocate, Manila)

I was born with Aortic Stenosis. Contributed to a congenital heart defect. I had a procedure when I was one to relieve the pressure, though when I was 14 it got too bad and required open heart surgery. I'll tell you what, every symptom he describes is true, and now 21 with a mechanical aortic heart valve, i'm not really sure what if i traded up or down lol. Anyways we do get better, it gets easier and life moves on. Anyone out there who understands what its like to go through all of this I'm here to say amen, i do too. Not alone guys!

I have just turned 60, working as RN, have found that I have AS, as well as bradycardia, just becoming symptomatic. I see a cardiologist, when is time to have valve replaced and pacemaker put in. Seems cardiologist is waiting, what for? Surely its best to do this while I am relatively fit and healthy.

Hi, your videos are really helpful. In aortic stenosis, you mention that the systemic circulation will dilate. I thought that in response to a decreased cardiac output, the systemic circulation would constrict and this is the reason why it is dangerous to cause a sudden drop in the SVR of patients with AS e.g. with GTN.

and how are things, 5 yrs later? what is your age and reason for valve replacement? i am 57 , recently diagnosed BAV, my mother who died 2 months ago had AFIB, was on warfarin etc,..... died due to stroke and heart attacks,...The cardiologist told me AFIB is not related to BAV.. i sure have been tired alot lately. i initialy went to doc with heart floppy feelings,... did a 30 day heart monitor, where, the sporadic pounding and abnormal rhythm idid not occur. I recently bought a pulseoximeter to monitor, due to COVID-19,.... and the last 2 -3 times i put it on for a reading,... i see my Pulse drops to 45 or so, and lingers in the 50s and 60s,..... (blood oxygen is 90-94%) Anyhow, I'm not really sure what to do from here. Card said he'll check it every couple of years,... but shouldn't i consider valve replacement now, while i am in fairly good health? instead of waiting for more bothersome symptoms,....more damage to occur? hmm,... i started out tonight looking for info in ketamine infusion therapy is safe for someone with BAV, to treat my depression. i welcome any feedback,... thanks.

Excellent video! I have a question about the walls of the left atria and ventricle. After an aortic valve has been replaced do the enlarged and stiffened walls return to normal? (maybe causing the afib to disappear? ) I ask because I am to receive a new valve in 2 weeks. Also scheduled is a cox maze procedure. Thanks for the great video. Kevin

@ranmasaotome6931 11 жыл бұрын

Great lecture! From my readings and lectures I thought that the most common cause of aortic stenosis is calcification of an aortic valve since it's most commonly seen in the elderly (>65y/o). In my study notes for AS under etiology, I wrote think calcification of AV unless px is young (bicuspid valve) or is a foreigner (rheumatic heart disease). Just my 2 cents on the topic. Guess I should start looking at journals more.

@TheDarkDutchman Жыл бұрын

Wow.... This really is very good, clear and precise explanation. Before I had the aortic valve replaced I had a lot of angina and syncope. 18:23 Only that part is not very precise (any more) because these day bioproyheses last much longer than 10 years. It's expected to last 15 to 20 years? Hopefully. I have one for 13 years now and there's only a little bit of deterioration visible.

@garyjene9146 Жыл бұрын

I would like to dispute some information of yours. For those that have a life expectancy of more than 10 years are not limited to a Mechanical valve replacement as you suggest. I received what is known as a Ross Procedure. While it may be a bit more complicated but like the bio prosthetic replacements does not require long term medication such as warfarin (coumidin). I had the Ross procedure done at the beginning of September 2022. If a person is relatively healthy and can handle open heart surgery and has more than 10 years of life expectancy, I would recommend this type of valve replacement. Look up the videos by Adam Pick.

@pnkbubblegumicecream 6 жыл бұрын

Informative video. However, I wouldn’t go so far as to proclaim a hard and fast rule that a bioprosthetic heart valve is best indicated for patients who have a life expectancy of less than 10 years. Bioprosthetic heart valves can be replaced via a less invasive procedure than open heart surgery, i.e. a “valve-in-valve TAVR” procedure. Moreover, socioeconomic and patient-specific factors should also be heavily considered when making the decision between bioprosthetic and mechanical valves. Warfarin can be quite tricky to dose correctly, and INR values can fluctuate wildly, especially with changes in diet, alcohol and cigarette consumption, and concomitant medications. Regular visits for INR reads may not be feasible for some patients. The risk for major bleeds and thromboembolic events may outweigh the benefits of a mechanical heart valve, even for younger patients.

Can you explain how LVEDV also goes up? I understand that LVEDP goes up from AS and the hypertrophied LV in a way to compensate for increased pressures. But wouldn't a less compliant and hypertrophied left ventricle have trouble filling? And wouldn't that decrease the LV volume? Maybe in the beginning the volume would be high because the LV can't pump the blood out effectively but I would think that over time with decreased compliance then the LV wouldn't be able to accept the volume from the LA.

So if all the procedures are not perfect, is there any medication or herbal preparation which can improve this severe aortic stenosis which the reader of Echo has evaluated for me.I am very thankful for your honesty stating all these procedure cannot be 100% or life time warranty then what we should do to overcome this situation. From religious point you said it can be made from pig or cow. Thus how should I survive. Need your helpful hand. Is it possible to take nitroglycerin to open these valves or not or that too will be fatal. I have high cholesterol and high blood pressure. Need your help in the form of advise, I read the same that these are temporary relief and you have to come back to have open heart surgery. Hoping to hear from you soon. God Bless.
