Association of hypertrophic maxillary frenulum with hypoplastic left heart syndrome

J Pediatr. 1995 Nov;127(5):749-50. doi: 10.1016/s0022-3476(95)70167-2.


We report a previously unrecognized association between a hypertrophic frenulum separating the alveolar portion of the maxillary palatine suture with hypoplastic left heart syndrome in one fetus and seven children. A hypertrophic frenulum was not found in 25 pediatric cardiology patients without hypoplastic left heart syndrome. This finding may provide a marker for suspecting hypoplastic left heart syndrome in the neonate.
