What is the most common cardiovascular abnormality in adults with Marfan's syndrome?

Aortic root dilatation is recognized as the most common cardiovascular abnormality in adults with Marfan's syndrome. This condition, which is a connective tissue disorder, often leads to structural changes in the heart and blood vessels. In particular, the aorta can become stretched or enlarged, resulting in aortic root dilatation, which can lead to serious complications, including aortic regurgitation and the risk of aortic dissection.

Marfan's syndrome is characterized by its impact on the structural integrity of connective tissues, affecting multiple systems in the body, most notably the cardiovascular system. The aortic root is particularly susceptible to these changes due to the inherent weaknesses in the elastic fibers that compose the vessel wall. Regular monitoring for aortic root dimensions is crucial in individuals with Marfan's syndrome to manage the risk of cardiovascular events.

Other options, while certainly relevant to cardiovascular health, do not represent the most common abnormality associated with Marfan's. Heart murmurs may be detected due to valvular insufficiency, but they are not as prevalent as aortic root dilatation. Coronary artery disease is less common in younger individuals with Marfan's compared to the general population, and arrhythmias, although possible, are not the
