Mortality/Morbidity
* Cardiovascular disease (aortic dilatation and dissection) is the major cause of morbidity and mortality.
* Progression from mitral valve prolapse to mitral regurgitation, often in conjunction with tricuspid prolapse and regurgitation, is the most common cause of infant morbidity. If untreated, Marfan syndrome is highly lethal; the average age at death is 30-40 years.
* Death after infancy usually involves ascending aortic dissection and chronic aortic regurgitation. Dissection generally occurs at the aortic root and is uncommon in childhood and adolescence.
