Pediatric cardiac tamponade caused by metallic wire penetration into the heart: A case report and literature review

Thin, metallic wires can easily penetrate the gastrointestinal system if ingested and cause serious cardiac issues in children. We report a pediatric case of such an object that caused cardiac tamponade after lodging in the left ventricle. The wire was extracted without cardiopulmonary bypass and a full recovery was made. Cardiac issues after ingestion of foreign objects are rare but immediate surgery is required for resolution.

Juvenile lupus, cytomegalovirus infection and cardiac tamponade: case report

ABSTRACT Objective: To describe a rare case of cardiac tamponade in a pediatric patient with systemic lupus erythematosus (SLE) and cytomegalovirus (CMV) infection, and to discuss the relationship between these morbidities, the diagnostic approach, and the possible treatments. Case description: A 9-year-old girl presented to the emergency department with severe dyspnea, muffled heart sounds, jugular vein distention, hemodynamic instability, and intense pallor. She had previously been followed up at the outpatient clinic for a six-month history of mild respiratory distress, polyarthritis, fever, and various cutaneous manifestations. Doppler echocardiogram revealed pericardial effusion. The patient was submitted to pericardiocentesis followed by water seal pleuropericardial drainage, with no complications. The investigation continued, with fulfillment of clinical and laboratory SLE criteria plus CMV antigenemia of 15/200,000 cells. Medications to control CMV infection and SLE were then initiated, with good clinical and laboratory response. Comments: Pediatric SLE commonly manifests in a more severe form, accounting for high morbimortality. Cardiac tamponade could be one of the first manifestations of SLE, which can also be precipitated by infectious agents, such as CMV, leading to diagnostic confusion and misleading the treatment. Changes in therapeutics must also be considered in the presence of both conditions. This study presents a juvenile SLE case aggravated by a CMV infection with the unusual manifestation of cardiac tamponade.%

Cardiac Tamponade as First Manifestation of Multiple Myeloma: a Case Report With Literature Review

Background: Multiple myeloma is a hematologic malignancy characterized by clonal proliferation of plasma cells, mainly in bone marrow. Extramedullary disease is reported in many cases and may occur at diagnosis, at progression, or during relapse phase. Pericardial involvement is a rare condition that usually occurs with advanced-stage disease. We report a rare case of plasma cell-based pericardial effusion with cardiac tamponade as a form of presentation of multiple myeloma.Case presentation: A 76-year-old woman was admitted to the emergency department for worsening shortness of breath, on segmental examination, she had dyspnea, engorged jugulars, muffled heart sounds and lower limb edema. A Chest X-ray demonstrated cardiomegaly with a mild left pleural effusion, laboratory data showed immunoglobulin G lambda, diagnosis of plasma cell-based pericardial effusion was established by pericardial fluid cytology. The patient received systemic chemotherapy, according to Melphalan-Prednisone and thalidomid protocol. Conclusion: Multiple myeloma with cardiac effusion should be considered for differential diagnosis of patients with recurrent and unexplained pericardial effusions.

Acute Cardiac Tamponade Secondary to Cardiac Vascular-Type Pleomorphic Leiomyosarcoma: Case Report

Soft tissue sarcomas represent <1% of all neoplasms. Leiomyosarcomas comprise only 5–7% of cases, and only 2% of these are vascular. Vascular leiomyosarcomas are extremely rare and represent only 0.001% of all neoplasms, the venous type being up to 5 times more frequent. Arterial leiomyosarcomas most frequently affect the great vessels, being fatal in most cases. In the reported cases of arterial leiomyosarcomas, the most frequently affected site is the pulmonary artery. We present the clinical case of 2 patients (a 42-year-old woman and a 36-year-old man) with a diagnosis of arterial pleomorphic leiomyosarcoma that conditioned cardiac tamponade as the initial manifestation. As it is an exceptionally rare neoplasm and with few cases reported in the literature, it is important to identify and describe this pathology which, due to the impossibility of offering surgical treatment, represents a therapeutic challenge.
