The Cardiovascular System: A Lifelong Concern
For Marfan patients, the heart and blood vessels are often the most critically affected systems throughout their lives, and this risk continues with age. Faulty connective tissue weakens the aorta, the body's main artery, and heart valves, issues that can become more pronounced over time.
Aortic Dilatation and Dissection
The most serious complication is a progressive enlargement, or dilatation, of the aorta, particularly at the aortic root. With aging, this chronic stress can increase the risk of a life-threatening aortic dissection, where a tear occurs in the inner layer of the aorta's wall. Regular monitoring via echocardiograms and other imaging is essential, with frequency increasing as patients age or if the aorta grows rapidly.
Heart Valve Malformations
Weakened connective tissue also affects heart valves, especially the mitral valve. Mitral valve prolapse (MVP), where the valve leaflets bulge back into the heart chamber, is common and its severity can progress with age, potentially leading to significant regurgitation and heart failure. The aortic and tricuspid valves can also be affected, requiring careful monitoring.
Arrhythmias
Aging Marfan patients have an elevated risk for heart rhythm problems, or arrhythmias, which can become more frequent over time. Ventricular arrhythmias have been linked to myocardial dysfunction and can increase the risk of sudden cardiac death.
The Musculoskeletal System: Increasing Pain and Weakness
The skeletal and joint issues that are hallmarks of Marfan syndrome can intensify with age, leading to new challenges for older patients. The characteristic joint hypermobility and weakened connective tissue can lead to progressive joint deterioration.
Osteopenia and Osteoporosis
People with Marfan syndrome are susceptible to low bone density (osteopenia) and osteoporosis at a younger age than the general population. The risk increases with age, making fractures a more significant concern for older patients. Regular bone density checks are recommended.
Degenerative Joint Disease
Loose ligaments and joint hypermobility, which are present from a young age, can lead to early-onset arthritis and chronic joint pain in adulthood. The hip sockets (acetabula) can be deep, a condition called protrusio acetabulae, which can accelerate arthritic changes and may necessitate hip replacement later in life.
Spinal Curvature
Spinal deformities like scoliosis or kyphosis can progress or cause increased pain as a person ages, potentially impacting mobility and breathing. Dural ectasia, the swelling of the sac around the spinal cord, is more prevalent in older Marfan patients and is a frequent cause of lower back pain, headaches, and leg discomfort.
The Ocular System: Heightened Risk of Vision Problems
While ectopia lentis (lens dislocation) is a common feature in younger Marfan patients, aging introduces additional eye health risks related to connective tissue weakness.
Early-Onset Cataracts and Glaucoma
Older Marfan patients face an increased likelihood of developing cataracts and glaucoma at an earlier age compared to the general population. Both conditions can lead to vision loss if not managed properly with regular eye exams.
Retinal Issues
Connective tissue defects also heighten the risk of retinal detachment or tears. Older patients with a history of lens extraction are at an even higher risk, and flashes or floaters in vision should prompt immediate medical attention.
The Pulmonary System: Risk of Lung Complications
Weakened connective tissue also affects the lungs, creating potential complications that can emerge or worsen with age.
Spontaneous Pneumothorax
The bursting of weakened air sacs in the lungs can cause a spontaneous pneumothorax, or collapsed lung. The risk of recurrence and bilateral pneumothorax is higher in Marfan patients, and breathing difficulties can increase with age.
Emphysema
Progressive emphysematous changes in the airways and apical lung bullae have been documented in aging Marfan patients. These changes, often without a smoking history, can lead to restrictive lung disease and require careful monitoring.
Long-Term Management and Outlook
Managing Marfan syndrome in later life involves a multidisciplinary approach focused on vigilance and proactive treatment. With improved medical and surgical care, patients can now expect a near-normal lifespan, but this also means more time for chronic, age-related complications to emerge.
Regular Monitoring and Care
Regular, consistent follow-up with specialists—including cardiologists, ophthalmologists, and orthopedists—is vital. A patient-centered, team-based approach is necessary to address the wide-ranging effects of this progressive disorder.
Proactive Treatments
This includes medication, particularly beta-blockers or angiotensin receptor blockers, to slow the progression of aortic dilatation and reduce heart stress. Timely, elective surgery to repair or replace the aorta can be lifesaving.
Lifestyle Modifications
Older patients may need to adapt their physical activity levels to avoid contact sports, heavy weightlifting, and other high-intensity exercises that put extra strain on the heart, joints, or eyes.
Comparison of Age-Related Effects
| Organ System | Key Features in Aging Marfan Patients | Standard Aging Comparison |
|---|---|---|
| Cardiovascular | Progressive aortic dilatation; increased risk of dissection; worsening valve regurgitation; arrhythmias. | Aorta generally stiffens and weakens gradually; valvular disease can occur but at a later average age and lower severity without Marfan. |
| Skeletal | Early-onset arthritis; increased chronic pain; higher prevalence of osteoporosis/osteopenia; potentially worsening scoliosis. | Joint pain and osteoporosis are common but typically begin at older ages; less pronounced and varied skeletal issues. |
| Ocular | Increased risk of early cataracts and glaucoma; potential for late-onset lens dislocation and retinal detachment. | Cataracts and glaucoma are common, but onset is typically later in life and progression is generally slower. |
| Nervous | More common and often more symptomatic dural ectasia, causing back pain and headaches. | Dural ectasia is specific to certain connective tissue disorders; not a standard feature of typical aging. |
| Pulmonary | Increased risk of spontaneous pneumothorax; progressive emphysema, often independent of smoking. | Lung function declines with age; emphysema is primarily associated with smoking and environmental factors. |

Conclusion
For aging Marfan patients, the core features of the disorder—cardiovascular, skeletal, and ocular—continue to evolve, often becoming more complex. The potential for worsening pain, cardiac risks, and vision problems makes lifelong, comprehensive medical management indispensable. By working closely with a team of specialists, monitoring vigilantly, and adapting their lifestyle, seniors with Marfan syndrome can effectively manage the long-term impacts of their condition.
