    Case of cerebrotendinous xanthomatosis with giant xanthomas and literature review
    (SPRINGER, 2023) Eliaçık, Sinan; Çil, Gülsüm
    Introduction Cerebrotendinous xanthomatosis (CTX) is a rare autosomalrecessive disease that occurs as result of mutation in the CYP27A1 gene. Theclinical presentation of the disease is quite wide. We planned to briefyreview the literature with this case diagnosed as a CTX. Case A 50-year-old male patient was admitted to the neurologyoutpatient clinic complaining of progressive worsening of his walking, andswelling in his legs. Mild mental retardation was detected in our patient. Inaddition to the visual impairment that would be explained by cataracts, he hadxanthomas in both lower extremities. Signs related to bilateral cataractsurgery and intraocular lens were detected during an eye examination. Therewere no abnormal fndings in electroencephalography, electroneuromyography, andbrain magnetic resonance imaging of the patient, whom we learned that hervisual impairment started in childhood. The Mignarri Suscipion Index index wascalculated as 275. A genetic examination was requested and the CYP27A1 gene wasp.A216P (c.The mutation 646G>C) (CM044609) was detected as homozygous. Conclusion Due to the lowawareness of CTX and the variability of its clinical fndings, its diagnosis maybe delayed for years, as in our patient. When diagnosed, most patients may havesevere, often irreversible neurological damage. With the early recognition ofthe CTX and the start of treatment, patients can have a chance to quality life.

    A rare cause of abdominal pain: Mesenteric panniculitis
    (2021) Düzenli, Tolga; Köseoğlu, Hüseyin
    A 54-year-old woman presented to the emergency department with complaint of abdominal pain lasting for 3 days. Her abdominal pain was in the epigastric region spreading to the left lower quadrant. Oral and IV contrasted abdominal computed tomography (CT) revealed inflammation surrounded by heterogeneous pseudocapsule in the mesenteric fatty tissue starting from the mesenteric root. This inflammation encircled the mesenteric artery and veins and there was a fat halo sign around the vein (Fig. 1). The patient’s condition significantly improved with conservative treatment including antibiotics (ceftriaxone i.v.) and nonsteroidal anti-inflammatory drugs (NSAIDs) (diclofenac i.m.).

    Evaluation of the relationship between platelet indices and spontaneous echo contrast in patients with mitral prosthetic heart valves
    (2020) Kalçık, Macit; Sayar, Ahmet Güner; Bayam, Emrah; Yesin, Mahmut; Kalkan, Semih; Gürsoy, Mustafa Ozan; Özkan, Mehmet Akif
    Objective: Spontaneous echo contrast (SEC) is defined as dynamic, smoke-like echoes within the cardiac cavities with a characteristic swirling motion seen on echocardiography. Clinical studies have demonstrated that SEC is a risk factor for left atrial thrombus formation and an important indicator for potential systemic embolism. Platelet indices have been associated with the presence of SEC in patients with mitral stenosis. The aim of this study was to investigate the relationship between platelet indices and SEC in patients with prosthetic heart valves. Methods: A total of 89 patients [female: 38 (42.4%); median age: 52 years (range: 36-67 years)] with SEC formation in the left atrium, and 257 control subjects [female: 123 (47.5%); median age: 56 years (range: 45-65 years)] without SEC formation were enrolled. All of the patients were evaluated by using transthoracic and transesophageal echocardiography. Laboratory tests including complete blood count and biochemical parameters were analyzed. Results: Patients with SEC formation had more frequent atrial fibrillation, higher left atrial diameter (LAD) and lower left ventriular ejection fraction values. Platelet indices including platelet count, platelet distribution width, mean platelet volume, and plateletcrit did not differ between the groups. Increased LAD was detected as the only independent predictor of SEC development. Conclusion: Platelet indices were not found to be associated with the presence of SEC formation in the left atrium among patients with mitral prosthetic valves. Therefore, the use of platelet indices alongside known echocardiographic and clinical risk factors to predict SEC development in patients with a mitral prosthesis is debatable.

    Diagnosis, treatment & management of prosthetic valve thrombosis: the key considerations
    (Taylor & Francis Ltd, 2020) Gündüz, Sabahattin; Kalçık, Macit; Gürsoy, Mustafa Ozan; Güner, Ahmet; Özkan, Mehmet
    Introduction: Prosthetic heart valve thrombosis is a life-threatening complication after valve replacement surgery. Although subtherapeutic anticoagulation is the main cause, there are many other conventional and esoteric predisposing factors. Areas covered: The etiopathogenesis, diagnosis, and management of prosthetic heart valve thrombosis with particular focus on conventional and esoteric predisposing factors, diagnosis with multimodality imaging and current therapeutic approaches were covered. Expert opinion: Subtherapeutic anticoagulation remains the key driving force for the development of prosthetic valve thrombosis. However, cardiologists should be cognizant of other frequent or rare conventional and esoteric causes. The diagnosis is now more straightforward with the use of multimodality imaging. Transthoracic and transesophageal echocardiography with or without real-time three-dimensional imaging are the current gold standard modalities. Multidetector computed tomography is now a major complementary tool. The favorable clinical outcomes with recently introduced slow or ultra-slow infusions of alteplase, as compared to relatively poor surgical results, have rendered thrombolytic therapy the first-line treatment option in most eligible patients with prosthetic valve thrombosis. Surgical treatment could be reserved in whom thrombolytic therapy is contraindicated or has already failed. The efficacy and safety of thrombolytic therapy as compared to surgery should be confirmed with large observational cohorts, and ideally randomized trials.

    A comprehensive review of the diagnosis and management of mitral paravalvular leakage
    (Turkish Soc Cardiology, 2020) Gürsoy, Mustafa Ozan; Güner, Ahmet; Kalçık, Macit; Bayam, Emrah; Özkan, Mehmet
    Mitral paravalvular leaks (PVLs) commonly occur in patients with prosthetic valves. Paravalvular defects may be clinically inconsequential and may aggravate hemolysis or cause heart failure through regurgitation. Accordingly, patients may eventually require intervention such as redo surgery or a transcatheter closure of the defects. The introduction of purpose-specific closure devices and new steerable catheters has opened a new frontier for the transcatheter PVL closure. This mode of treatment is an initial therapy in most centers with experienced structural heart team. However, head-to-head data comparing two treatment modalities (surgery and transcatheter closure) are limited, and the world-wide experience is based on nonrandomized studies. Multimodality imaging, including three-dimensional transesophageal echocardiography, facilitates the delineation of mitral PVLs and provides essential data that aids the communication between the members of the structural heart team. In the near future, the success of interventional therapies will most probably increase in patients with mitral PVLs with the introduction of hybrid imaging modalities (echocardiography, cardiac computed tomography, and fluoroscopy). In conclusion, this paper summarizes the etiopathogenesis, clinical characteristics, diagnosis, and treatment of mitral PVLs.
