title: Noncardiac chest pain in adolescents and children with mitral valve prolapse.
abstract: Chest pain in adolescents and children is usually not of cardiac origin. Of cardiac conditions commonly linked to chest pain in childhood, mitral valve prolapse (MVP) is the most prevalent, but this association has recently been questioned. In light of recent reports of gastroesophageal sources of chest pain in adults with MVP, we performed a comprehensive gastroesophageal evaluation of 17 preadolescents and adolescents with mitral valve prolapse who had chest pain as their presenting symptom. Evaluation consisted of esophageal manometry, Bernstein test, esophageal pH probe, and/or esophagogastroscopy. Fourteen of the 17 patients had at least one abnormal finding. Five patients had esophagitis, five had gastritis, one had high-amplitude esophageal contractions, one had abnormal esophageal manometry with positive Bernstein test, one had esophageal reflux and positive Bernstein test, and one had abnormal manometry with esophageal reflux. The 13 patients with esophagitis, gastritis, reflux, or positive Bernstein test were treated with antacid, with resolution of chest pain in 12 patients. Two of these patients underwent follow-up endoscopy with documentation of improvement. The patient with high-amplitude esophageal contractions was treated with dicyclomine, which resulted in resolution of chest pain. The observation that the chest pain was not related to mitral valve prolapse is important in clinical practice and raises further questions as to whether mitral valve prolapse causes chest pain.
