What Is Marfan Syndrome?
Marfan syndrome is a hereditary connective tissue disorder caused by mutations in the FBN1 gene, which encodes fibrillin-1 — a protein essential for the structural integrity of connective tissue throughout the body. Because connective tissue is found in virtually every organ system, Marfan syndrome can affect the cardiovascular system, eyes, skeleton, lungs, and skin.
The condition affects approximately 1 in 5,000 people worldwide, regardless of sex or ethnicity. While it is inherited in an autosomal dominant pattern, up to 25% of cases arise from new (de novo) mutations with no family history.
Marfan syndrome is a lifelong condition, but with expert multidisciplinary management — including regular cardiac surveillance, timely surgical intervention, and ophthalmologic care — patients can live full, active lives.
Key Features of Marfan Syndrome
Marfan syndrome presents across multiple organ systems. The most life-threatening manifestations involve the cardiovascular system, but the diagnosis is often first suspected based on skeletal or ocular findings.
Cardiovascular (Most Critical)
- Aortic root dilation and aortic aneurysm — the aorta gradually enlarges, increasing the risk of aortic dissection or rupture, which can be fatal if untreated
- Aortic dissection — a tear in the inner wall of the aorta; a medical emergency requiring immediate surgery
- Mitral valve prolapse (MVP) — the mitral valve leaflets bulge backward, potentially causing mitral regurgitation
- Aortic regurgitation — leakage of the aortic valve due to root dilation
Ocular
- Ectopia lentis — dislocation of the eye lens (present in ~60% of patients), causing blurred vision
- Myopia (nearsightedness) — often severe and early-onset
- Increased risk of retinal detachment and glaucoma
Skeletal
- Tall stature with disproportionately long limbs, fingers, and toes (arachnodactyly)
- Scoliosis or kyphosis
- Pectus excavatum (sunken chest) or pectus carinatum (pigeon chest)
- Hypermobile joints and flat feet
- High-arched palate
Other Systems
- Lungs: spontaneous pneumothorax (collapsed lung)
- Skin: stretch marks (striae) unrelated to weight change
- Dura: dural ectasia — enlargement of the dural sac surrounding the spinal cord, causing lower back pain
Diagnosis: The Revised Ghent Criteria
Marfan syndrome is diagnosed using the Revised Ghent Nosology (2010), which assigns a systemic score based on clinical features and incorporates genetic testing and family history. Key diagnostic anchors include:
- Aortic root Z-score ≥ 2 on echocardiography
- Ectopia lentis confirmed by slit-lamp examination
- Pathogenic FBN1 mutation identified on genetic testing
- Positive family history of confirmed Marfan syndrome
A systemic score ≥ 7 points (based on skeletal, skin, lung, and other features) combined with aortic involvement or FBN1 mutation confirms the diagnosis.
Why Seek Treatment in Shanghai?
Shanghai is home to China's most advanced cardiovascular surgery centers, with internationally trained specialists who perform high volumes of complex aortic and valve procedures. For Marfan syndrome patients — who often require multiple surgeries over a lifetime — access to experienced teams with cutting-edge technology is critical.
Key advantages of seeking care in Shanghai include:
- High surgical volume: Shanghai's top hospitals perform hundreds of aortic root surgeries annually, with outcomes comparable to leading Western centers
- Multidisciplinary teams: cardiologists, cardiac surgeons, vascular surgeons, ophthalmologists, orthopedic surgeons, and geneticists working in coordinated teams
- Advanced imaging: 3D CT angiography, cardiac MRI, and intraoperative echocardiography for precise surgical planning
- Valve-sparing techniques: experienced surgeons offer valve-sparing aortic root replacement (David procedure) to preserve the native aortic valve — particularly important for younger patients
- Cost-effectiveness: world-class care at a fraction of the cost compared to the US or Europe
Recommended Hospitals in Shanghai for Marfan Syndrome
Zhongshan Hospital (复旦大学附属中山医院)
One of China's top-ranked hospitals, Zhongshan Hospital has a world-class cardiac surgery and cardiovascular medicine program. The hospital's cardiac surgery team performs high volumes of aortic root replacement, valve repair, and complex aortic procedures. The cardiology department, led by experts including Dr. Ge Junbo, provides comprehensive pre- and post-operative cardiac management. Zhongshan is particularly strong in minimally invasive cardiac surgery and structural heart disease.
Ruijin Hospital (上海交通大学医学院附属瑞金医院)
Ruijin Hospital's cardiac surgery department, led by Dr. Zhao Qiang, is one of Shanghai's premier centers for complex cardiac and aortic surgery. Dr. Zhao's team has extensive experience with aortic root replacement, valve-sparing procedures (David operation), and total arch replacement — all procedures commonly required in Marfan syndrome patients. Ruijin also offers strong multidisciplinary support including rheumatology and genetics.
Changhai Hospital (海军军医大学第一附属医院 / 长海医院)
Changhai Hospital's vascular surgery department is nationally recognized for aortic disease management. The team has expertise in both open surgical and endovascular approaches to aortic aneurysm and dissection. For Marfan patients with complex aortic pathology, Changhai offers advanced hybrid procedures combining open surgery with endovascular stenting. The hospital's vascular surgery team, including specialists associated with Dr. Fu Weiguo's network, provides comprehensive aortic care.
Shanghai Ninth People's Hospital (上海交通大学医学院附属第九人民医院)
For the ophthalmologic manifestations of Marfan syndrome — particularly ectopia lentis, retinal detachment, and glaucoma — Shanghai Ninth People's Hospital is one of China's leading eye centers. The hospital's ophthalmology department has specialists in complex lens surgery, vitreoretinal surgery, and glaucoma management, making it an essential referral center for Marfan patients with significant ocular involvement.
Huashan Hospital (复旦大学附属华山医院)
Huashan Hospital offers strong orthopedic and spine surgery capabilities for Marfan patients with significant skeletal manifestations, including severe scoliosis requiring surgical correction. The hospital's multidisciplinary approach also includes neurology support for patients with dural ectasia.
Treatment Approach for Marfan Syndrome
Medical Management (Lifelong)
- Beta-blockers (e.g., atenolol, metoprolol) — reduce aortic wall stress and slow aortic dilation; first-line therapy for all Marfan patients
- ARBs (e.g., losartan) — may provide additional benefit in slowing aortic root growth, particularly in pediatric patients
- Activity restrictions — avoidance of competitive sports, heavy lifting, and contact sports to reduce aortic stress
- Regular surveillance — annual echocardiography (or more frequent if aorta is enlarging) to monitor aortic root diameter
Surgical Intervention
Surgery is recommended when the aortic root diameter reaches ≥ 50 mm (or ≥ 45 mm in patients with rapid growth, family history of dissection, or significant valve regurgitation). Surgical options include:
- Valve-sparing aortic root replacement (David procedure) — the gold standard for younger Marfan patients; preserves the native aortic valve, avoiding lifelong anticoagulation
- Bentall procedure — replacement of the aortic root and valve with a composite graft; used when valve preservation is not feasible
- Total arch replacement — for patients with aneurysm extending into the aortic arch
- Mitral valve repair — for significant mitral regurgitation
Ophthalmologic Care
- Annual slit-lamp examination and dilated fundus exam
- Lens extraction and intraocular lens implantation for significant ectopia lentis
- Retinal detachment repair (vitreoretinal surgery)
- Glaucoma management (medical or surgical)
Orthopedic Care
- Bracing or surgical correction for progressive scoliosis
- Pectus repair for severe chest wall deformity
- Physical therapy for joint hypermobility and musculoskeletal pain
