Annual aortic imaging surveillance
Regular MRI, CT angiography, or echocardiography to monitor aortic dimensions, dissection risk, and vascular tree involvement. Essential for surgical timing decisions.
Disease management and monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Beta-adrenergic blockade
Beta-blocker therapy to reduce aortic stress by decreasing heart rate and contractility. Slows aortic growth and reduces dissection risk in connective tissue disorders.
Additional treatment options
Elective aortic root replacement
Preventive surgical intervention when aortic root reaches threshold diameter (typically 4.5-5.0cm) or shows rapid growth. Uses valve-sparing or valve-replacing graft techniques.
surgicalActivity restriction and exercise modification
Avoidance of competitive sports, heavy lifting, and Valsalva maneuvers. Light to moderate aerobic exercise generally permitted. Stress importance of maintaining cardiovascular health without excessive strain.
lifestyleGenetic counseling and psychosocial support
Comprehensive genetic counseling for patients and families regarding inheritance patterns, family screening implications, and reproductive options. Psychological support for anxiety and adjustment.
