Pssst! It's me, the website.

I just wanted to let you know that even though I'm looking quite old, I'm still a millenial.
So I just had a "New Year, New Me" moment and my resolution is to become a new and improved version of myself in a couple of weeks.
Don't worry, my wisdom won't change. You're still going to find the same useful information here. Stay tuned!

Echo-of-the-Day Information
The Echo-of-the-Day is a presentation of 1 or more video loops to present an important topic in echocardiography. Please reveiw the image or video loops and then answer the questions below. After you have answered the questions you can view the explanation and obtain CME credit (if available).

You can change the size and the format of the image or video loops by using the links below the image or video loop.

Aortic Regurgitation
Case#: 91
AMA CME Units: 0.25 Units
Estimated Time: 15 minutes.
A patient presents aortic regurgitation murmur. The following echo loops where imaged from the patient.
Case Discussion
The echocardiographic findings are ascending aortic aneurysm, sinotubular junction effacement, severe aortic regurgitation, sidel lobe artifact in the ascending aorta probably from a PAC, normal aortic valve apparatus except for the dilated and effaced sinotubular junction (STJ).

The diagnosis is severe aortic regurgitation from an ascending aortic aneurysm that disrupted the sinotubular junction:aortic valve annulus ratio. The cause of the aortic aneurysm is most likely due to a connective tissue disease (Marfan's Syndrome, Ehlers-Danlos syndrome, idiopathic cystic medial degenreation) because of the STJ effacement. Other causes of ascending aortic aneurysms (hypertension, BAV) do not usually cause effacement of the sinotubular junction/Sinuses of Valsalva.

The aortic regurgitation is severe.  The jet is wide and exceeds 66% of the LVOT diameter.  Since the aortic valve is relatively normal, replacing the ascending aorta (modified Bentall/David  procedure) should be able to correct the aortic regurgitation.
