Mitral valve prolapse in juvenile thyrotoxicosis
Puerto Rico Health Sciences Journal
|August 1, 1991
Summary
Juvenile thyrotoxicosis may be associated with mitral valve prolapse. Echocardiography is recommended for hyperthyroid children with apical systolic murmurs to detect this potential link.
Area of Science:
- Pediatric Endocrinology
- Cardiology
Background:
- Juvenile thyrotoxicosis is a condition affecting children, leading to an overactive thyroid gland.
- Mitral valve prolapse is a condition where heart valve leaflets bulge into the left atrium during contraction.
Observation:
- A study examined 13 children (ages 8-17) with juvenile thyrotoxicosis.
- Physical examination, chest X-rays, ECGs, and echocardiography were used for assessment.
Findings:
- Two out of 13 thyrotoxic patients (15%) showed echocardiographic evidence of mitral valve prolapse.
- This prevalence is higher than the 1.7% observed in a control group.
Implications:
- The findings suggest a potentially higher frequency of mitral valve prolapse in children with hyperthyroidism.
- Echocardiography is advised for hyperthyroid children presenting with apical systolic murmurs to screen for mitral valve prolapse.
