[The rupture of a cardiac hydatid cyst located in the right ventricle]. / Rotura de un quiste hidatídico cardíaco situado en ventrículo derecho.

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.

[Ventricular tachycardia in a patient with mid-ventricular hypertrophic myocardiopathy and apical aneurysm]. / Taquicardias ventriculares sostenidas en un paciente con miocardiopatía hipertrófica medioventricular y aneurisma apical.

A case is presented of a 77-year-old patient who was admitted with a pattern of sustained ventricular tachycardia and diagnosed with midventricular hypertrophic myocardiopathy with apycal aneurysm. Under treatment with amiodarone at low doses, the patient is asymptomatic with no recurrence of the arrhytmias at one year. The association of midventricular hypertrophic myocardiopathy with apycal aneurysm and of those with sustained ventricular tachycardia are reviewed in conjunction with their treatment.
