Introduction

Marfan syndrome, also known as Marfan syndrome, includes cardiovascular diagnostic criteria such as aortic root dilation, aortic valve insufficiency, mitral valve prolapse, congenital cardiovascular abnormalities, and aortic root Z-scores. If abnormalities are detected, timely medical consultation is recommended. Marfan syndrome is an inherited connective tissue disorder. In addition to the diagnostic methods mentioned above, genetic testing can also be used for confirmation.

Marfan syndrome, also known as Marfan syndrome, has cardiovascular diagnostic criteria including aortic root dilation, aortic valve insufficiency, mitral valve prolapse, congenital cardiovascular abnormalities, and aortic root Z-score. If any abnormalities are detected, timely medical consultation is recommended. Detailed analysis is as follows:

1. Aortic Root Dilation

Aneurysmal dilation of the aortic root is a typical cardiovascular manifestation of Marfan syndrome. In healthy individuals, the diameter of the aortic root should be less than 30 mm, whereas patients with Marfan syndrome often have a diameter two to three times greater than normal, typically exceeding 60-70 mm. This can be assessed using imaging techniques such as echocardiography, CT, or MRI.

2. Aortic Valve Insufficiency

Aortic valve insufficiency causes blood to regurgitate from the aorta back into the left ventricle during cardiac contraction, thereby impairing normal heart function. A diastolic murmur in the aortic valve area can be detected via auscultation, and echocardiography can clearly demonstrate the presence of aortic valve insufficiency.

3. Mitral Valve Prolapse

Mitral valve prolapse prevents the mitral valve from fully closing during cardiac contraction, resulting in blood regurgitation, which can be diagnosed using echocardiography.

4. Congenital Cardiovascular Abnormalities

Patients with Marfan syndrome may also have congenital cardiovascular abnormalities such as atrial septal defect, ventricular septal defect, and tetralogy of Fallot. These abnormalities can be identified through imaging examinations such as echocardiography, CT, or MRI.

5. Aortic Root Z-Score

The aortic root Z-score is a method used to evaluate the degree of aortic root dilation. In the diagnosis of Marfan syndrome, a Z-score of the aortic root ≥ 2 is considered an important diagnostic criterion.

Marfan syndrome is an inherited connective tissue disorder. In addition to the diagnostic methods mentioned above, genetic testing can also be used for definitive diagnosis.

When do eye problems occur in Marfan syndrome?

In general, Marfan syndrome, also known as Marchesani syndrome, is associated with varying individual differences in the timing of eye-related problems. Some patients experience rapid growth and development and may encounter eye issues during childhood or adolescence. Others have slower growth rates and may not notice eye-related problems until the disease progresses to a certain stage.

Why does Marfan syndrome cause arterial dissection?

Marfan syndrome, also known as Marfan syndrome, is associated with an increased risk of arterial dissection due to several factors including genetic predisposition, fragile connective tissue, aortic root aneurysm, abnormal vascular wall structure, and hemodynamic changes. Therefore, patients with Marfan syndrome need to closely monitor their cardiovascular health and promptly diagnose and treat potential risks of arterial dissection.

What are the symptoms of Marfan syndrome?

In general, Marfan syndrome refers to a type of autosomal dominant hereditary connective tissue disorder. The symptoms mainly include cardiovascular system abnormalities, skeletal system disorders, ocular symptoms, skin abnormalities, and symptoms related to muscles and joints. These symptoms may appear individually or simultaneously, and their severity may vary.

What is the progression of Marfan syndrome from childhood to adulthood?

Marfan syndrome is a hereditary connective tissue disorder whose progression is typically associated with the patient's growth and development, including childhood, adolescence, and adulthood, gradually manifesting a series of symptoms as age increases. Currently, there is no specific treatment for Marfan syndrome; however, interventions such as medication and surgery can be employed to slow disease progression and reduce the risk of complications.
