[Angina and myocardial ischemia related to a fistula between the anterior interventricular artery and the pulmonary artery in a 56-year-old man].

The authors report a case of fistula between the left anterior descending artery (LAD) and the pulmonary artery (PA), in which the only clinical expression was angina associated with electrical signs of myocardial ischaemia on exertion. In the absence of any other signs of left-right shunt related to the fistula, the initial diagnosis was that of atherosclerotic coronary artery disease, especially as this 56-year-old man presented three risk factors. Coronary angiography revealed this anomaly and corrected the diagnosis.

[Severe aneurysmal dilatation of the left atrium. Apropos of a case].

The authors report the case of an eleven year old child with aneurysmal dilatation of the left atrial appendage and underline the diagnostic value of Doppler echocardiography in this affectation. The two signs which led to investigation of the patient and the diagnosis of this rare congenital abnormality were bulging of the left heart border on chest X-ray and atrial fibrillation. In addition to visualising a left para-cardiac chamber communicating with the left atrium on transthoracic and transoesophageal echocardiography, colour Doppler confirmed an exchange of blood between the two chambers.

[Results of percutaneous mitral dilatation in 11 cases of poorly tolerated mitral stenosis during pregnancy].

The authors report the results of percutaneous mitral dilatation (PMD) during pregnancy in 11 cases of tight and poorly tolerated mitral stenosis (MS). This dilatation was performed on average at 22 +/- 5 weeks of pregnancy, protecting the fetus against radiation and using the double balloon technique. Fluoroscopy time, with a mean of 10.

[Study of cor triatriatum. Apropos of 6 cases].

The authors report 6 cases of triatrial heart with various and non-specific manifestations and attribute the difficulty of its clinical identification above all to the frequency of associated lesions, which were present in 5 of the 6 cases reported here. An atrial septal defect and left superior vena cava were each seen twice while a ventricular septal defect, sub-valvular aortic stenosis, mitral insufficiency and transposition of the great vessels were each seen once. It was routine echocardiography which led to the discovery of triatrial heart in each of these 6 cases.
