RESUMO
Key Clinical Message: This case report presents an uncommon variant of Ebstein anomaly, where all three tricuspid valve leaflets exhibited apical displacement-a rare finding. It illustrates the complexities in diagnosing and managing such atypical presentations, with successful surgical correction through annuloplasty. The report adds valuable insights to the limited literature on this congenital heart disease. Abstract: Ebstein anomaly (EA), a rare congenital heart disorder, presents with diverse clinical spectrums. This case report explores a distinctive manifestation of EA, where all three tricuspid valve (TV) leaflets exhibited apical displacement, highlighting a novel aspect in the presentation of this condition. A 44-year-old woman, under long-term medical surveillance for EA, showcased an atypical clinical trajectory marked by the apical displacement of all TV leaflets, which is uncommon in EA. Despite a predominantly asymptomatic course, recent exacerbation of symptoms prompted further evaluation. Diagnostic modalities, including echocardiography and cardiac magnetic resonance imaging, revealed severe tricuspid regurgitation concomitant with unprecedented apical displacement of the anterior, septal, and posterior tricuspid leaflets. The displacement of the anterior leaflet was contrary to typical embryonic valvular formation expectations, indicating a unique presentation within EA. The patient underwent annuloplasty surgery, which successfully rectified the anomalous TV architecture. Postoperative evaluation demonstrated mild residual tricuspid regurgitation, and the patient was discharged in stable condition. This case underscores the variability in EA presentations and accentuates the significance of tailored surgical interventions. The observation of apical displacement involving all TV leaflets adds a unique dimension to the existing EA literature, reinforcing the need for careful diagnosis and personalized treatment approaches.
RESUMO
Key Clinical Message: We introduced one of the rare causes of intra-cardiac mass, that is, ECD and a new gene mutation (SLC29A3) that is probably related to this disease, and we noted the importance of using several diagnostic methods to rule out other intra-cardiac causes. Abstract: Edheim-Chester disease is a rare histiocytosis affecting multiple organs. The infiltration of lipid-laden histiocytes characterizes the disease. Most patients experience bone involvement; over 50% of cases involve the cardiovascular system and other extra-osseous organs. In this case report, we present the case of a 42-year-old man who complained of shortness of breath and bone pain. During echocardiography, a large, homogenous, and fixed mass was found in the right atrium free wall. Computed tomography and cardiac magnetic resonance imaging revealed an infiltrative mass in the RA with atrioventricular groove involvement but coronary sinus encasement, right coronary artery, and superior vena cava encasement. Abdominal CT scans also reported aortic wall involvement and bilateral renal cortical and perirenal involvement. A kidney biopsy confirmed the infiltration of histiocytes and the diagnosis of ECD. The treatment was initiated for him, and his symptoms improved. In this case report, we express the importance of considering the rare causes of cardiac tumors.
RESUMO
Statins and non-statin medications used for the management of dyslipidemia have been shown to possess antitumor properties. Since the use of these drugs has steadily increased over the past decades, more knowledge is required about their relationship with cancer. Lipid-lowering agents are heterogeneous compounds; therefore, it remains to be revealed whether anticancer potential is a class effect or related to them all. Here, we reviewed the literature on the influence of lipid-lowering medications on various types of cancer during development or metastasis. We also elaborated on the underlying mechanisms associated with the anticancer effects of antihyperlipidemic agents by linking the reported in vivo and in vitro studies.
