title: Mandibular Advancement Device-Emergent Central Sleep Apnea Can Resolve Spontaneously: A Case Report.
abstract: The development of treatment emergent central sleep apnea (CSA) has been described after almost all obstructive sleep apnea (OSA) therapies. While the course of positive airway pressure (PAP) emergent CSA, is better established; little is known about the natural course of mandibular advancement device (MAD) emergent CSA. Previous reports failed to comment on its natural course or report treatment with advanced ventilator modes such as adaptive servoventilation. We describe spontaneous resolution of MAD emergent CSA in a patient with moderate OSA who refused PAP. We also highlight the need for follow up polysomnography (PSG) after maximal advancement with a MAD and the possible association between MAD emergent CSA and atrial fibrillation. The exact pathophysiology of this phenomenon remains unclear but may relate to high loop gain of the respiratory system resulting in ventilatory overshoot after treatment and atrial fibrillation associated increased susceptibility to periodic ventilation.
