Which of the following is a common complication of Marfan syndrome?

Mitral valve prolapse is indeed a common complication associated with Marfan syndrome, which is a genetic disorder affecting connective tissue. Marfan syndrome is characterized by a range of cardiovascular, skeletal, and ocular manifestations, primarily due to abnormalities in the connective tissue.

The heart and blood vessels are particularly affected, with individuals often experiencing valvular heart disease. Mitral valve prolapse is specifically relevant, as it occurs when the mitral valve, located between the left atrium and left ventricle of the heart, does not close properly. This can lead to mitral regurgitation, where blood leaks backward into the left atrium during contraction, potentially resulting in arrhythmias or heart failure if severe.

The relationship between Marfan syndrome and cardiovascular issues highlights the importance of regular cardiac evaluations in affected individuals to monitor for complications, including mitral valve prolapse. Other options, while relevant to respiratory or cardiac health, do not have the same direct association with the pathophysiology of Marfan syndrome. Chronic bronchitis and asthma are primarily pulmonary conditions linked to environmental factors or smoking rather than connective tissue disorders, and heart block, while possible in some patients, is less frequently observed than complications like mitral valve prolapse.
