[The rupture of a cardiac hydatid cyst located in the right ventricle].

Heart involvement in echinococcal disease is rare, but it is more infrequent the location of cysts in the right ventricle. We report a case of a male 35 years old with hydatid cysts located in the right ventricle. The condition was diagnosed by two-dimensional echocardiogram performed after the rupture of the cysts leading to massive pulmonary embolism and subsequently right heart failure. Early diagnosis appears mandatory in an attempt to modify, applying the appropriate therapy, the natural evolution of this potentially lethal condition.
