Abstract
SUMMARY
C
oarctation of the aorta (CoA) is the most frequent congenital anomaly of the thoracic aorta, consisting of a narrowing usually located in the proximal descending aorta just distal to the left subclavian artery.
Isolated coarctation can remain clinically silent until adolescence or adulthood, presenting as primary hypertension with symptoms like headache, leg fatigue and leg cramps.
In CoA echocardiography is most useful in infants and children. In adults suprasternal notch view is most helpful; color Doppler can be used to localize the site of turbulence. Continuous wave Doppler can assess the pressure gradient.
Multislice computed tomography (MSCT) angiography has recently been introduced as a noninvasive method in the detection and quantification of coarctation.
The aim of the work to evaluate the correlation between echocardiographic and MDCT angiographic findings of significant aortic coarctation.
The study included 25 patients with suspected or confirmed aortic coarctation by echocardiography and clinical picture; they will undergo MDCT angiography in thr period from November 2013 and august 2014.
The suitable patients were subjected to thorough history taking and clinical examination, echocardiography and MDCT angiography.
Data were collected and analyzed after all 25 patients underwent echocardiography, multi-slice CT and cardiac catherization. The degree of stenosis was considered significant in 25 cases.
All coarctations were diagnosed correctly by multiplanar and three dimensional images with 100% sensitivity. Echocardiography missed the diagnosis of coarctation of aorta in 2 cases which was confirmed after these patients underwent cardiac catheterization.
In conclusion MDCT angiography is the method of choice in preoperative morphologic assessment of coarctation of the aorta in pediatric and adult patients.
We recommend another long term study that include larger number of patients.
