Fragmentation of a right atrial myxoma presenting as a pulmonary embolism.

We report here a tricky case of right atrial myxoma with a pulmonary localization mimicking pulmonary thromboembolism. The diagnosis on imaging investigation was delayed because of its atypical appearance. This case report emphasizes the leading role of transthoracic and transesophageal echocardiography in the management of this condition.

[Triangular or rectangular rehabilitation after myocardial infarction. Comparative study by drawing of lots evaluating performance and respiratory gas exchange].

Triangular and rectangular rehabilitation techniques were assessed by comparative exercise performance and respiratory evaluation in twenty six phase II post-myocardial infarction patients. Patients all performed a standard exercise test with measurement of VO2, before and after 40 rehabilitation sessions. Clinical, exercise and ventilatory parameters were identical in the two groups before rehabilitation (triangular--n = 13; rectangular--n = 13).

[Measurement of cardiac output by CO2 rebreathing technique. A study of reproducibility in the normal subject; application to cardiac insufficiency].

A feasibility and reproducibility study of cardiac output measurement by CO2 rebreathing was performed in normal subjects and in patients with compensated cardiac failure. The measurements were performed at rest and at the second stage of the Bruce protocol in normal subjects (N = 12) with a good reproducibility (r = 0.81) after an interval of two days.

[Return to work after myocardial infarction: evaluation and decision].

Working capacity after myocardial infarction depends on the physical and cardiovascular status, psychological repercussions and conditions of work. The latter two are much more important than the first two factors. Cardiovascular functional status is readily assessed by the large number of available investigations which leave little unknown.
