BACKGROUND: The typical cardiac manifestations of Marfan syndrome are aortic 
regurgitation with progressive dilatation of the aortic root, which may cause 
dissection and rupture of the ascending aorta, mitral valve prolapse and mitral 
valve regurgitation. In this study, we aimed to show echocardiographic findings 
in 11 patients with Marfan syndrome.
METHODS: Diagnosis of Marfan syndrome was based on the Ghent criteria. All 
patients had a full echocardiographic evaluation. During the evaluation, we 
investigated the presence of mitral valve prolapse, mitral valve regurgitation, 
tricuspid valve prolapse, dilatation of the aortic root, and aortic 
regurgitation.
RESULTS: Eleven patients were diagnosed as Marfan syndrome (seven male, four 
female, age 4-14 years). All had mitral valve prolapse (nine with mitral valve 
regurgitation). Among these 11 patients, seven had accompanying tricuspid valve 
prolapse, six had dilatation of the aortic root and two had aortic 
regurgitation.
CONCLUSION: Eleven patients in our clinic were diagnosed as Marfan syndrome 
since they had distinct characteristics of marfanoid phenotype. 
Echocardiographic evaluation of these patients showed marked heart valve 
involvement. In Marfan syndrome, it is known that the aortic valve is affected 
following mitral valve involvement. In our experience, aortic root dilatation is 
less common. However, particular attention should be given to following up 
aortic root status with noninvasive echocardiography to institute measures to 
prevent complications.
