Vaccines "in general" are good, but I don't think they're good for me. That's what I've decided and I'm definitely not going to get vaccinated.

I'm afraid that such a study is neither sufficient nor convincing. Pre-existing health problems should be considered and discussed with doctors before you take the risk of inoculation with an experimental serum for which neither the manufacturer assumes responsibility. As for my vaccination, 40...

You vaccinate to protect yourself, not to protect someone else or grandma. The fact that those vaccinated can carry the virus and infect others, reinfect themselves and even die after the vaccine, makes the theory of social contract and conditional freedom, used to force people to get...

TAVR is a fast and efficient aortic valve replacement procedure. A major concern would be that the durability of this tissue valve is not known, especially in the latter types.

"the objective of this study was to compare the EARLY hemodynamic changes after aortic valve replacement between ATS, Bicarbon, and On-X mechanical valves. ....................... There was no difference in the postoperative aortic prosthetic mean pressure gradient between groups when stratified...

Increased gradients are not a cause but an effect of the effort of the heart to pump blood; aortic stenosis was the cause of a great effort of the heart and for the hypertrophy of the ventricle. By the mechanical valve replacement, the obstruction has been removed, the pressure in the aorta has...

One or more of the following factors can mimic a heart attack on the electrocardiogram: ●Physiologic and positional effects ●Myocardial injury or replacement ●Ventricular enlargement

Regarding the mean gradient values of aortic mechanical valves (MPG), there is a fairly recent and suggestive study for brands ATS, BICARBON and ON-X. The measured values for valves between 18 mm and 25 mm at 6 months after surgery were 17.04±8.4 mmHg for ATS, 21.5±12.9 mmHg for BICARBON and...

AV mean PG 7.2 mmHG

The mean gradients are inversely proportional to the size of the valves, the large ones of 25 or 27 mm result in gradients below 10 mmHg. Your result is truly exceptional only 7 days after surgery. In my case, with a 23 mm valve (the most common, I think), the mean gradient decreased from a much...

In the case of the mechanical valve, the mean gradient will most likely fall below 20 in 3-6 months, physical movement is highly recommended, 10000 steps daily would be desirable.

AVR + bypass December 2020, Sorin Carbomedics Standard 23 mm Preoperative: - severe aortic stenosis - aortic gradient mean 61 - VMAX 4.88 - ejection fraction 25-30 - hypertrophy of the left ventricle, Three months after surgery: - mean aortic gradient 14 - VMAX 2.45 - ejection fraction >...

Yes, excellent values, they were expected from a 27 mm aortic valve.

OK, Thank you !

It's about mean aortic pressure gradient [PG], it is measured in mmHg and is calculated on ultrasound of the heart.
