What are the echocardiography findings in Marfan syndrome?

Marfan syndrome, also known as Marfan syndrome, is a congenital, hereditary connective tissue disorder. Echocardiography results from patients may show features such as aneurysmal dilation of the aortic sinus, aortic valve prolapse, mitral valve prolapse, mitral regurgitation, and aortic regurgitation. If abnormalities are detected, timely medical consultation is recommended. Detailed analysis is as follows:

1. Aneurysmal dilation of the aortic sinus: This is one of the typical cardiovascular manifestations of Marfan syndrome. Echocardiography can clearly display the dilation of the aortic sinus.

2. Aortic valve prolapse: The aortic valve may prolapse into the left ventricular outflow tract. Echocardiography using color Doppler during diastole can detect regurgitant flow signals, which are clear indicators of aortic valve prolapse.

3. Mitral valve prolapse: In Marfan syndrome, the mitral valve may prolapse into the left atrium. Color Doppler echocardiography during systole can detect eccentric regurgitant signals, which are important signs of mitral valve prolapse.

4. Mitral regurgitation: Due to mitral valve prolapse, mitral insufficiency may occur. Echocardiography can visualize the regurgitation across the mitral valve.

5. Aortic regurgitation: Aortic regurgitation may be observed on echocardiography due to aortic root dilation and aortic valve insufficiency.

Once these characteristic findings are identified, further investigations such as genetic testing and imaging studies including CT or MRI should be performed to confirm the diagnosis and formulate an appropriate treatment plan.
