Good points. To add to your comments, it will help immensely to know your wiggers diagram like the back of your hand. You are guaranteed questions on...
Probably the best rule is to put the sample volume (small: 2-3 mm) just before the flow acceleration that begins at the annulus (LVOT or RVOT) level. To do...
Thankyou Mark. Your images were great. Never thought that Subcostal short axis view would demonstrate Main Pulmonary artery and branches as beautifully as you...
Yes, I agree, sample volume PW Doppler placement should be consistent?for both LVOT and RVOT measurements. We measure?diameters and outflow velocities?just...
there are plenty of Tangent(just abit more lateral and lower space)Â views to open up the MPA and the Biafrication.. if that still won't bring it out..try...
Thought I would share this with those of you who may not have read this. New Mexico has passed a state licensure bill requiring state licensure for all...
Dear all, Is there any link to download this book.. Echocardiography in pediatric heart disease. Second edition I'll be gratefull best regard, Dr.Fadi Shinnar...
Hello Group, I'm looking to relocate to Florida. I'm a registered Cardiac Sonographer with 2 years exp. I've seen it all when it comes to pathologies, where...
Dear all, a debate broke out in our case review meeting with surgeons, sonographers and cardiologists recently. Please can you tell me what you all do with...
Hey Jan,  I don't blame you for wanting some fun in the sun. I moved the other direction, from FL back North, for same reason, family.  Anyways, I...
From what I've read and experienced, I think someone previously commented here and had the best advice. To forgo the AVA for prosthetic valves and focus on...
Jane, Here is a copy of one of my posts to the group from back in March. The new ASE recommendation is to measure the LVOT diameter. I do both. These...
In our lab we don't measure the LVOT in prosthetic valves, a measurment is already given for prosthetic valves. Jan ________________________________ From: Jane...
In our lab we most follow gradients not area. Occasionally we will use the LVOT/AV ratio and we rarely follow AVA. I do believe the ASE has a Prosthetic...
It sounds like a weighted average accounting for these two approaches would work well and provide the physicians with the insights they need regarding any...
For those interested, I found that a "preview" of the The Echo Manual is available on Google Books. Many pages have been ommitted, however you can still view...
For those who are interested, I found some pictures/diagrams related to this discussion -- might help to provide further context. Â 3 attachments. Â Cliff ...
I should probably clarify my comment of not measuring the LVOT. We use the calipers to measure it, take the picture, but do not save it into the calculation...
We recommend - in our lab - to evaluate both gradients and valve areas (continuity equation for aortic valves, PHT for mitral). This evaluation must be...
Yes, good points. The IE33 does this as well-- will provide and send/deliver any measurements if the key data points are there (of course I'm pretty sure...
That ASE document is going to prove very useful going forward. According to a number of sources, when catheter-facilitated heart valve replacements become...
Nancy, The peak and mean gradient can vary significantly from one study to the next due to differences in rhythm (heart rate) and loading conditions. I do not...
Hi, Jan. I wish you the best of luck in finding what you want, where you want it. As a personal caution, you might want to re-think your outlook in this...
Mark,  I read through your message again and I think I understand you better. But, just to be clear-- you are taking the sewing ring size as a "known...
I had a patient over the weekend with a prosthetic valve which I had gotten a 0.5 cm sq valve area on, by continuity equation. I know this is pretty tight, but...
Your physician is correct. You can't have a large hole in the valve in diastole and tight opening in systole. What were the LVOT and AV peak and mean...
Cliff, That is correct. The sewing ring size becomes a known constant. If this information is not in the chart, the patient may have a card from the...
to keep it simple, the priority control determines the shade of grey at which color can be overwitten on the 2d image to represent motion. in other words, if...
