Why the study?
Are esophageal motility disorders the cause of chest discomfort in certain patients with mitral valve prolapse?
Are esophageal motility disorders the cause of chest discomfort in certain patients with mitral valve prolapse?
Chest pain in patients with mitral valve prolapse may be caused by esophageal motility disorders rather than the cardiac condition itself.
May indicate esophageal spasm as alternative cause of chest pain in mitral valve prolapse; leaves open broader applicability.
The cause of chest pain associated with mitral valve prolapse remains unclear. A young woman with chest pain ascribed to mitral valve prolapse is described. Response of chest discomfort to atenolol therapy had been poor. The patient's chest discomfort and concomitant esophageal spasm were provoked by intravenous infusion of edrophonium chloride during esophageal manometry. A Bernstein acid infusion test also induced her chest pain. Review of systems revealed intermittent dysphagia and postprandial heartburn. In certain patients with mitral valve prolapse, esophageal motility disorders may be the cause of chest discomfort.
