Which cardiac abnormalities are commonly associated with Marfan's syndrome?

• A. Aortic stenosis and mitral regurgitation
• B. Mitral prolapse and aortic root dilation
• C. Atrial septal defect and ventricular hypertrophy
• D. Coronary artery disease and arrhythmias

Answer: (B)

Marfan's syndrome is a genetic disorder that affects connective tissue and is known for its association with various cardiovascular abnormalities. The most significant cardiac issues linked to Marfan's syndrome include mitral valve prolapse and aortic root dilation. Mitral valve prolapse occurs due to an abnormality in the connective tissue of the heart, leading to the valve's improper closure during heartbeats, which can result in mitral regurgitation over time. Aortic root dilation is a critical concern as it can lead to aortic aneurysm or dissection, both of which are potentially life-threatening complications. The dilation occurs due to the weakening of the connective tissue surrounding the aorta, making it less stable and more prone to damage. In contrast, the other options mention cardiac abnormalities that are either less commonly associated with Marfan's syndrome or do not directly link to the primary connective tissue defects that characterize the syndrome. Therefore, options presenting other cardiac conditions related to Marfan's syndrome are not the primary concerns connected to this genetic disorder. Understanding these specific associations is critical for management and monitoring in patients diagnosed with Marfan's syndrome.
