[Nitrid oxide, levosimendan and sildenafile in a patient with right ventricle dysfunction and severe pulmonary hypertension after cardiac surgery].

Pulmonary hypertension (PHT) and the resulting right ventricle dysfunction are important risk factors in patients who undergo cardiac surgery. The treatment of PHT and right ventricle dysfunction should be focused on maintaining the correct right ventricle after load, improving right ventricle function and reducing the right ventricle pre-load and therefore reducing pulmonary vascular resistance by means of vasodilators. A combined therapy of vasodilators and medicines which have different mechanisms of action, is becoming an option for the treatment of PHT.

[Right ventricular myxoma. A rare case of pulmonary stenosis].

We discuss a case of a fourteen year old girl in whom, clinical signs of right ventricular outflow obstruction were discovered following a syncopal attack. A right ventricular tumor was observed by echocardiography. Histology confirmed the diagnosis of myxoma.
