[Dilated cardiomyopathy in a patient with Eosinophilic Granulomatosis with Polyangiitis (Churg Strauss)].

Eosinophilic granulomatosis with polyangiitis, formerly known as Churg-Strauss Syndrome, is a rare pathology that belongs to the group of diseases characterized by necrotizing vasculitis of small and medium-sized systemic blood vessels. Symptomatic cardiovascular involvement occurs in 27% to 47% of Churg-Strauss cases, being one of the most serious manifestations. The diagnosis is usually confirmed with tissue biopsy showing eosinophil infiltration, but in selected cases with the recent inclusion of cardiac MRI, we can dispense with it.

[Mechanical fragmentation and catheter-guided thrombolysis in intermediate risk pulmonary embolism].

Acute pulmonary thromboembolism remains a significant cause of morbidity and mortality worldwide. Its diagnosis, risk stratification and early treatment are essential. The mainstay of treatment is anticoagulation.

[Percutaneous balloon angioplasty for treatment of chronic thromboembolic pulmonary hypertension].

Chronic thromboembolic pulmonary hypertension is characterized by the presence of organized thrombotic material in the pulmonary arteries which causes elevation of the pulmonary vascular resistance, right heart failure, and death if not treated. Pulmonary thromboendarterectomy is the treatment of choice and can be curative when the obstruction is proximal. There are cases in which this therapy is not possible, and pulmonary angioplasty is a therapeutic alternative of growing interest.
