Intracardiac Thrombosis Secondary to the Silent Killer: A Case Report about Monoxide Carbon Poisoning in a Child

Carbon monoxide (CO) poisoning is a frequent cause of emergency room admissions, especially during winter days, the symptoms are varied ranging from a simple headache to a serious cardiac and neurological impairment that can be deadly. Diagnosis is based on the circumstances of occurrence as well as the dosage of carboxyhemoglobin in the blood. Exposure to CO has serious consequences, neurological and cardiac manifestations are not negligible and vary from repolarization disorders to heart attack. Treatment is urgent with normobaric or hyperbaric oxygen therapy. We report a case of a 2-year male child admitted to the emergency room for CO intoxication with an intracardiac thrombus subsequently complicated by an ischemic stroke with a fatal outcome in order to highlight this complication rarely described in literature.

Right Ventricular Thrombus and Tricuspid Valve Dysfunction in a Patient with Behçet’s Disease

Background: Behçet’s disease (BD) is a multisystemic, chronic inflammatory disorder with a broad range of manifestations including within the cardiovascular system. Cardiac involvement like intracardiac thrombus (ICT) and valvular involvement in BD are rarely seen entities and often associated with poor prognosis. Case Presentation: We present the case of a young patient with vascular-Behçet diagnosed by the presence of intracardiac thrombus in the right ventricle, unresponsive to medical treatment. Even though the intracardiac lesion was successfully treated by surgical excision, he presented a severe tricuspid dysfunction some years later due to the extension of fibrosis with no surgical therapeutic option. Conclusion: Intracardiac thrombosis is a rare but early manifestation of Behçet’s disease, which is difficult to diagnose and has a poor prognosis.
