[Incidence and predictive factors of mitral insufficiency in surgically treated aortic stenosis. Transthoracic and transesophageal ultrasonographic evaluation].

Mitral regurgitation is common in adults with aortic stenosis. When severe, it may aggravate the clinical condition and pose an additional therapeutic problem. The authors studied 40 consecutive patients with severe surgical aortic stenosis prospectively by transthoracic echocardiography and pre-operative transoesophageal echocardiography to determine the incidence, mechanism and degree of mitral regurgitation and its eventual relationship to the aortic stenosis.

[Peripheral embolic arterial accident due to pulmonary vein thrombosis revealing bronchial carcinoma].

The authors report a case of left superior pulmonary vein thrombosis discovered on transoesophageal ultrasonography in the context of aetiological assessment of a systemic vascular accident. This unusual site of a thrombus on an anatomically perfectly normal left atrium led the authors to perform a more detailed assessment, revealing a previously undiagnosed lung cancer on thoracic CT scan.

[Pulmonary embolism and thrombi of the right heart].

In general, there are two types of right heart thrombi diagnosed by echocardiography: mobile and non-mobile thrombi, more often located in the atrium than in the ventricle and a potential source of pulmonary embolism. However, they differ in several points: clinical context, clinical and echocardiographic presentations, embolic potential, prognosis and treatment. The result of peripheral venous thrombosis, mobile thrombus it is usually diagnosed during echocardiographic investigation of pulmonary embolism.
