Background: Refsum disease is a rare autosomal recessive hereditary disorder of lipid metabolism that results in the accumulation of phytanic acid. This syndrome is characterized with a range of classic symptoms including ataxia, peripheral neuropathy, amyotrophy, retinopathy, ichthyosis, and hearing loss. Later in life, individuals with Refsum disease may present cardiac manifestations, such as arrhythmias or conduction defects (first-degree atrioventricular block and bundle branch block) and hypertrophic or dilated cardiomyopathy, leading to heart failure and sudden death. To the best of our knowledge, this is the first case revealed by cardiac manifestations described in literature., Case Presentation: We report the case of 38-year-old white Moroccan male who was admitted in our department for an acute decompensated heart failure episode. Transthoracic echocardiography found a dilated cardiomyopathy with a reduced ejection fraction at 15%. Further evaluation showed different features of Refsum disease. High plasma level of phytanic acid confirmed the diagnosis. Cardiac manifestations are frequent in the late course of the adult Refsum disease and include, cardiomyopathy, electrical abnormalities, and sudden cardiac death. Moreover, arrhythmias remain one of the main causes of death in these patients., Conclusion: Refsum's disease is an autosomal recessive disorder. It presents as retinitis pigmentosa with anosmia, deafness ataxia, and cardiac defects. Current interventions for individuals with Refsum disease consist of dietary phytanic acid restriction and lipid apheresis to control symptoms and enhance quality of life., (© 2024. The Author(s).)

Background: Stent dislodgement is a life-threatening complication that can result in coronary artery embolization, stent thrombosis, acute myocardial infarction, and even death. Severely angulated, heavily calcified, and previously stented coronary arteries are associated risk factors. With the development of different lesion preparation techniques and the drug eluting stent era, the reported incidence of stent dislodgement has decreased to < 1% in the last few years., Case Presentation: We report a case of a 64-year-old Moroccan man complicated during percutaneous intervention in the left main artery by the loss of two stents. This complication was successfully managed by passing the stent's balloon into the stent and then fully expanding it. In our case, the device's characteristics were involved and could play a role in such complications, but it is still not well understood., Conclusions: The main treatment option is stent retrieval with different available techniques. If retrieval of the stent is impossible, crushing it against the blood vessel wall could be considered., (© 2024. The Author(s).)

Background: Myeloproliferative neoplasms (MPNs) such as polycythemia Vera (PV) and Essential Thrombocythemia (ET) can be associated with a high risk of both venous and arterial thrombosis. However, the co-existence between these two complications is very rare and has never been described before, especially in young adults with no known history of MPNs., Case Presentation: We report the case of a 39 year-old Caucasian Moroccan male patient without cardiovascular risk factors (CVRF), who presented with acute chest pain. He also suffered from a severe headache since 2 weeks. Electrocardiogram (ECG) showed ST segment elevation myocardial infarction in the posterolateral leads. Cerebral Computed Tomography (CT) scan revealed subarachnoid hemorrhage (SAH), and cerebral Magnetic Resonance Angiography (MRA) found a Superior Sagittal Sinus Thrombosis (SSST). Routine blood tests showed raised hemoglobin and hematocrit in addition to leukocytosis and thrombocythemia. His coronary angiography revealed a thrombus in the ostial left circumflex artery (LCX). Further testing revealed positive Janus kinase 2 (JAK2) V617F mutation and low erythropoietin level, confirming the diagnosis of PV according to the 2008 World Health Organization (WHO) criteria. Antithrombotic and anti-ischemic treatments, in addition to myelosuppressive therapy with hydroxyurea, were initiated with a good clinical and biological evolution., Conclusion: This case shows that MPNs are an important cause of thrombosis, especially in young patients with no other risk factors. Early diagnosis and appropriate management are fundamental before the occurrence of life-threatening complications that can sometimes present in unusual forms associating arterial and venous thrombotic events.
