[Right ventricular dysfunction and ischemia in pulmonary embolism].

Patients with pulmonary embolism and right ventricle dysfunction (determined with clinical, hemodynamic or echocardiographic methods) are a subgroup at high risk for complications. One of the pathogenic factors of right ventricular dysfunction in pulmonary embolism is myocardial ischemia, usually secondary to hemodynamic overload, and sometimes worsened by underlying coronary artery disease. We described a patient with pulmonary embolism and dyskinesia of the right ventricular free wall, related to chronic atherosclerotic occlusion of the right coronary artery proximal to the acute marginal branches that irrigate the free wall.
