MVP is commonly associated with which defect?

• A. Vsd
• B. Secundum ASD
• C. PFO
• D. PDA

Answer: (B)

Mitral valve prolapse tends to show up with other connective-tissue–related or valve abnormalities, and among common congenital defects the strongest association is with a secundum atrial septal defect. This pairing appears more frequently together than with other defects, likely reflecting shared underlying connective tissue factors rather than a direct cause-and-effect relationship. Ventricular septal defect, patent foramen ovale, and patent ductus arteriosus are not as strongly linked to MVP in typical exam contexts, so the pairing with a secundum ASD is the best match. When MVP is seen on imaging, it’s reasonable to also look for a secundum ASD, which may be detected with color Doppler or bubble studies if clinically suspected.
