A 12 year-old female Caucasian athlete came to our institution to attend a pre-participation screening for competitive athletic sports eligibility:
- Her family history was negative for sudden cardiac death (SCD), ischemic heart disease, or cardiomyopathies
- Her mother was diagnosed with a mild mitral valve prolapse (MVP)
- No personal history of pre-syncope or syncope was reported
In the context of a transthoracic echocardiogram, required for the finding of a grade 2/6 proto-midsystolic murmur during a routine pediatric exam, the athlete was diagnosed with:
- MVP, mitral-annular disjunction (MAD) (10 mm)
- Associated with a mild mitral regurgitation
In her recent medical history, she reported an occasional feeling of exercise independent cardiac palpitations.
