[Tamponade reveals an intra-pericardial hydatid cyst - a case report]. / Tamponnade révélant un kyste hydatique intra-péricardique - un cas.

INTRODUCTION: Hydatid disease is a parasitic infection caused by the development of the larval form of the Teania of Echinococcus granulosus. It is endemic in many regions of the world such as the Mediterranean basin. Location without pericardial cardiac involvement is extremely rare. In this case study, we will elaborate the case of an intra-pericardial hydatidosis disease without cardiac location revealed by a tamponade. OBSERVATION: AA is a 60-year-old man with no pathological history and who was admitted for a tamponade assessment. Indeed, the cardiovascular examination showed a muffling of the heart sound and signs of a right heart failure. Besides, the ECG shows a microvoltage, and the chest radiography shows cardiomegaly. Moreover, the transthoracic echocardiogram confirmed the presence of an abundant pericardial effusion along with signs of a tamponade. It also reifies the presence of, at the intra-pericardial level, a multiple vesicular formation giving a cluster of grapes highly suggestive of an intra-pericardial hydatid disease. An emergency surgical drainage allowed removing about two liters of suspicious fluid along with cysts and white membranous. The pathological examination of the membranous confirmed the diagnosis of a pericardial hydatid cyst. The performance of a chest CT and an abdominal ultrasound's scan to identify other locations shows no further anomalies. The patient was put under medical treatment (Albendazole(®)) and is showing a good clinical improvement. CONCLUSION: The intra-pericardial hydatid disease is another cause of tamponade not to fail despite its rareness, as it is endemic to North African countries.

Cardiac tamponade via a fistula to the pericardium from a hydatid cyst: case report and review of the literature.

Although echinococcus is endemic in many sheep-raising areas of the world, cardiac involvement is rare. Cysts usually reach the heart by means of the coronary circulation, but other routes have been proposed. Pericardial tamponade due to a hydatid cyst has not yet been described in the literature. We present the case of a 46-year-old woman who presented to the Emergency Department with complaints of chest pain and mild dyspnea. Her medical history was positive for a liver hydatid cyst operation 26 years earlier. She was tachypneic, tachycardic, and hypotensive. Pleural and pericardial effusions were detected on transthoracic echocardiography. When she worsened clinically, pericardiocentesis was performed and she promptly improved. A fistula was detected between the liver and pericardium on computed tomography (CT) scan of the torso. Serologic test (agglutination) for Echinococcus granulosus was positive in a 1/32 dilution. A final diagnosis of mediastinal hydatic cyst was made, and a 4-week course of albendazol was given. Then the cyst was surgically excised, and the patient recovered without complications.

Fatal cardiac tamponade in malarial acute renal failure.

Uremic hemorrhagic pericarditis occurs much less frequently in acute than in chronic renal failure, but when it does, it is a potentially fatal complication. The possibility of hemorrhagic pericarditis and cardiac tamponade should be considered in patients with acute renal failure and acute hemodynamic instability. This study reports a case of falciparum malaria complicated by acute renal failure that developed fatal cardiac tamponade in the recovery phase of acute renal failure.

Taponamiento cardiaco por quiate hidatídico pericárdico / Cardiac tamponade caused by hydatid pericarditis

Presentamos el caso de una mujer sin antecedentes personales de interés que debuta con insuficiencia cardiaca con clínica de taponamiento cardiaco por pericarditis hidatídica secundaria a fistulización a traves del diafragma por rotura de quista hidatídico localizado en hígado. La hidatidosis cardiaca es poco frecuente presentado una incidencia según series entre el 0,2-2% sobre el total de infestación en humanos por Echinococcus, siendo la afectación pericárdica infrecuente. Es por ello que realizamos revisión de su etiopatogenia, presentación clínica, diagnósticos de elección y tratamientos recomendados

We present the case of a woman with no previous clinical history of disease, that debuted with acute heart failure with symptoms of cardiac tamponade from hydatic pericarditis as a result of a fistula across the diaphragm secondary to a hidatidic cyst rupture in the Uver. Cardiac hydatidosis is rare with an incidence in some series betweem 0.2-2% in humans infested with Echinococcus, affectation of the pericardia being rare. For this reason we present a revision of its pathogenesis, clinical presentation, diagnosis and recommended treatment

Emerging acute Chagas Disease in Amazonian Brazil: case reports with serious cardiac involvement

Four cases of serious cardiac attacks by autochthonous Trypanosoma cruzi infection from the Brazilian Amazon are reported; three of them occurred in micro-epidemic episodes. The manifestations included sudden fever, myalgia, dyspnea and signs of heart failure. Diagnosis was confirmed by specific exams, especially QBC (Quantitative Buffy Coat) and natural xenodiagnosis. Despite treatment with benznidazol, three patients died with serious myocarditis, renal failure and cardiac tamponade. The authors call attention to the emergence of this disease and reveal a previously unknown pathogenicity of T. cruzi strains in this area, added to a non-usual transmission form.

Amoebiasis: a rare cause of cardiac tamponade.

Cardiac tamponade secondary to perforation of a hepatic amoebic abscess developed six years after the patient had visited an area where Entamoeba histolytica is endemic. He was treated with metronidazole and imipenem, emergency percutaneous catheter drainage, and open surgical drainage.
