Midweek we started learning about hypertension, aneurysms, and aortic dissection. We touched briefly on Marfan syndrome, a genetic disorder of the connective tissue. People with Marfan’s tend to be unusually tall, thin, with thin, long limbs and fingers. Weakening of the connective tissue in the ascending aorta can cause aneurysm or dissection, the latter of which killed playwright and composer Jonathan Larson. He died the day before opening night of Rent.
