There is no available evidence that supports withholding therapeutic hypothermia in these patients. There are no long-term data on neonatal outcomes. We report the case of a 28-year-old pregnant patient with long QT syndrome who experienced multiple cardiac arrests during the second trimester and underwent therapeutic hypothermia, cardiac ablation, transvenous pacemaker placement, and placement of an implantable cardioverter defibrillator (ICD). She subsequently delivered a viable infant at term. The evidence seems to support the use of hypothermia during pregnancy, but patients should be counseled about the unknown maternal and fetal risks and long-term neonatal outcomes. Decisions to utilize therapeutic hypothermia should be made on an individual basis.Pneumomediastinum is the presence of aberrant air in the mediastinum and is most commonly caused by oesophageal or alveolar rupture. Hyperemesis gravidarum is persistent nausea and vomiting before the 20th week of pregnancy and can increase intra-thoracic pressure, precipitating pneumomediastinum. #link# A 22-year-old patient presented with hyperemesis gravidarum in the 6th week of pregnancy. During her hospital admission, she developed chest pain, and imaging showed pneumomediastinum. Endoscopy excluded oesophageal perforation, a diagnosis of spontaneous pneumomediastinum was made, and her symptoms improved with conservative management. This case demonstrates how oesophageal perforation and spontaneous mediastinum can present in similar fashion. Oesophageal perforation has high morbidity and mortality and it is vital to identify it early. It is therefore important that clinicians are aware of pneumomediastinum as a potential complication of hyperemesis gravidarum and exclude oesophageal perforation in these individuals.The ever
