In Marfan patients, MVP is related to which chest wall deformity?

• A. scoliosis
• B. pectus carinatum
• C. kyphosis
• D. pectus excavatum

Answer: (D)

In Marfan syndrome, mitral valve prolapse often accompanies a set of connective-tissue–related abnormalities, including chest wall deformities. The most characteristic chest wall change in this condition is pectus excavatum, a funnel-shaped depression of the sternum. This association reflects the same underlying tissue fragility that predisposes to both MVP and the chest wall abnormality. While scoliosis or kyphosis can occur in Marfan, and pectus carinatum can be seen as well, pectus excavatum is the deformity most classically linked with MVP in these patients.
