Hydatid Cyst disease involves the heart in 0.02-2% of the cases. It can appear with symptoms very similar to coronary artery disease, cardiac valvular disease and pericarditis. We present a case of hydatid cyst that was located on the posterior tricuspid leaflet and that caused tricuspid regurgitation in 37 year old female patient who has gone through hydatid cyst excision from the bilateral lungs with median sternotomy 2 years ago. In addition to the right atrial and ventricular dilatation, second degree tricuspid regurgitation and significant pulmonary hypertension was found. The 2 x 2 cm smooth surfaced mass was resected from the posterior leaflet of the tricuspid valve and the defect was closed with suture with the aid of cardiopulmonary bypass. The patient followed with long term albendazole treatment. Cardiac echinococcosis should be kept in mind in some patients throughout their life with a history of previous hydatid cyst disease. Surgical excision without rupture is the treatment of choice for cardiac hydatid cyst, with following medical therapy in order to prevent recurrence.

    ABSTRACT: Introduction- Cardiac hydatid cysts usually involve other organs and in different sites of the heart. Treatment of heart hydatid cysts is usually surgical, followed by continuous medical therapy. We present a male patient with a hydatid cyst in the interventricular septum with compression effect on the left anterior descending artery (LAD); the cyst was diagnosed with echocardiography, CT imaging, and angiography. The patient was treated via surgical excision of the cyst under cardiopulmonary bypass, and the treatment was continued with medical therapy. A follow-up, the patient was in good physical condition. Cardiac echinococcosis is uncommon, accounting for 0.5% to 3% of all hydatid infestations in human beings1. All the heart walls and cavities can be the site of hydatid development but hydatid cysts of the heart are located most often in the left ventricle. Involvement of the interventricular septum is rare and can cause symptoms arising from the compression of the atrioventricular conduction pathway and obstruction of the right or left ventricular outflow tract1,5. Diagnosis is with echocardiography, CT imaging, and occasionally angiography 1,2,4. There is always the lethal hazard of cyst perforation. Early diagnosis and an integrated treatment strategy are crucial. The results of the surgical treatment of heart echinococcosis are better than those of the conservative strategy only. Extraction of the cyst combined with chemotherapy perioperatively or postoperatively is aimed at decreasing recurrence2.

    ABSTRACT: Cardiac valve cysts are rare beyond infancy. The tricuspid and mitral valve are the most common sites, with few reported cases of pulmonary valve cysts in the literature. This case illustrates a pulmonary valve cyst mimicking a tumour in a child 13 years after cardiac surgery. Although these lesions are extremely rare, they could be considered in the differential diagnosis in patients presenting with valvular mass lesions.

    ABSTRACT: Hydatid cyst is a parasitic disease caused by Echinococcus granulosus whose people is the intermediate host. Although this parasite can settle in any part of the human body, it is frequently seen in liver and lungs. The rate of unusual located hydatid cyst outside of liver and lungs is 13,9%. In this study, we aimed presenting unusual located hydatic cysts regarding 51 patients. In this retrospective study, the files of the patients operated in our department between 2005 and 2012 with the diagnosis of hydatid cyst, characterized be an additional location besides liver and lung involvement and located outside of liver and lung were controlled. We had a total of 51 patients between the ages of 6-79 (average age 35,34), 20 of them were men (39%) and the others were women (61%) (men/women = 1.56). The cysts outside of liver and lung were frequently seen in spleen (24/51), ovarium (9/51), intraabdominal (8/51), brain (8/51), kidney (6/51), psoas muscle (1/51), bladder (1/51), cervical lymph node (1/51), the heart(1/51) respectively. The most frequent symptom in our patients was stomachache. Besides, symptoms of cough, fever, respiratory disorder were present; only one patient suffered from hemophtysis. While 32 patient out of 51 were treated by laparotomy, 8 patients were operated with laparotomy and thoracotomy in the same session; the patient with 2 ovarian cysts was submitted to cystectomy through laparoscopic surgery. As a patient had a cyst both in brain and liver, he was submutted to laparotomy and craniotomy. 46 cysts in 9 patients with lung involvement were treated with lung resections: 7 wedges resection and 2 segmentectomies. The other lung cysts of the analysed patients were treated by cystectomy and capitonnage. Bile leakage was detected in a total of 7 patients: 3 of them were treated with T tube drainage and the others were endoscopically healed by means of ERCP. The incidence of hydatid cyst, which is an important health problem in endemic areas, can be reduced by means of simple preventive measures. Its basic treatment is surgery. Main objective of the surgery should be parenchyma sparing while taking off completely the cysts. Although the disease is frequently seen in liver and lung, other organ involvements should be considered. Thus, it does not matter where hydatid cyst is seen, abdomen and thorax should be attentively controlled by the simplest imaging method also outside of clinical symptoms. Abdomen and thorax imaging should be carried out at least once in the two following years to have an early detection of an eventual recurrence.
