[Chronic atrial fibrillation in adults: direct current cardioversion or medical cardioversion].

To study cardioversion modalities of atrial fibrillation, we had a look to 100 cases hospitalized in Mongi slim cardiologic department during the period lasting from January 1993 to July 2001. Medical cardioversion (with amiodarone) was performed in 47 patients and electrical cardioversion in 53 patients. Atrial fibrillation was 17 months old.

[Echocardiography under perfusion with dobutamine. Experience of Tunisian cardiologic service. About 70 cases].

We report a prospective study which began on February 1st, 1999. 70 consecutive and non selected patients got dobutamine stress echocardiography. The major indication, in 53% of cases, was detection of coronary disease in patients suffering from chest pain but whose stress testing were not conclusive.

[Left main coronary stenosis: clinical and paraclinical aspects].

The authors report a retrospective study about 20 cases of left main coronary disease admitted during 7 years. The mean age is 60 years with a large predilection for men (65% cases). The left main coronary stenosis generally presented as instable angina in 45% cases, myocardial infarct in 40% cases and left ventricular dysfunction in 10% cases.

[Mitral valve repair using Alfieri technique: necessary indication in a case].

Carpentier techniques for valve repair remain our first choice to deal with mitral insufficiency. This case is of a 65 years old woman scheduled for mitral valvuloplasty. Using conventional procedure was prevented by unfavourable anatomic conditions (lack of papillary muscles with chordaes supported by several tiny trabeculations).
