Echocardiography in aortic root dissection and dilatation
Insights
Echocardiography is a highly effective tool for diagnosing aortic dissection and dilatation. This imaging technique accurately identified most cases, aiding in patient management and follow-up.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Aortic root dissection and dilatation are serious cardiovascular conditions.
- Accurate and timely diagnosis is crucial for effective patient management.
Purpose of the Study:
- To evaluate the diagnostic utility of echocardiography in patients with aortic root dissection and dilatation.
- To compare echocardiography findings with angiography in diagnosing aortic dissection.
Main Methods:
- Echocardiography was performed on six patients with confirmed aortic root dissection and six with aortic root dilatation.
- Angiography was used as a comparative diagnostic tool for aortic dissection.
- Echocardiography parameters including left ventricular function and aortic regurgitation were assessed.
Main Results:
- Echocardiography diagnosed aortic dissection in 5 out of 6 patients, with a characteristic double echo finding.
- Angiography was diagnostic in 4 out of 6 patients with dissection.
- Echocardiography revealed an enlarged aortic root in all patients with dilatation.
Conclusions:
- Echocardiography is a valuable, non-invasive method for diagnosing aortic root dissection and dilatation.
- The double echo sign on echocardiography is a key indicator of aortic dissection.
- Echocardiography plays a significant role in the diagnosis, management, and follow-up of these aortic conditions.
Abstract:
Six patients with aortic root dissection proved by angiography, surgery or autopsy, and six patients with aortic root dilatation were studied by echocardiography. Echocardiography was diagnostic in five or six patients with dissection and suggestive in the sixth, disclosing anterior and posterior dissection in three, anterior dissection in one and posterior dissection in one. The recording of a double echo in the aorta was the diagnostic feature. Angiography was diagnostic in four of the six patients, yielded a false negative result in one and was not performed in one. Six patients with dilatation had an enlarged aortic root by echocardiography. Left ventricular size, stroke volume, ejection fraction, aortic regurgitant flow and velocity of circumferential fiber shortening were calculated in 11 patients. Echocardiography was extremely helpful in the diagnosis, management and follow-up in patients with aortic dissection or dilatation.
