[Atrial flutter ablation: initial experience in a general hospital].

Background: Right atrial flutter has a relatively high incidence. It is often symptomatic and can have a poor outcome particularly in case of thrombo-embolic events.

Aim Of Study: We evaluate the results of radiofrequency catheter ablation for right atrial flutter since the introduction of this technique inour hospital.

[Heart valve diseases specific in rheumatoid polyarthritis. Apropos of 2 cases].

Rheumatoid nodules represent a rare cardiac valvular involvement in rheumatoid arthritis. Patients are usually asymptomatic. We report two cases of such involvement: one presented as a tumour implanted on the mitral valve, with systemic embolisation; the other presented as aortic regurgitation with acute heart failure.

[Continuous ambulatory electrocardiographic recordings using the Holter system in the late phase of hospitalization for recent myocardial infarct. Value and limitations studied in a series of 100 patients].

Repeated continuous ambulatory electrocardiography by Holter monitoring was performed after early mobilisation post-myocardial infarction in 100 patients, without ventricular extrasystoles on classical ECG. Frequent ventricular arrhythmias were recorded in 58 p. 100 cases, unrelated to the localisation of the infarct.

[Are stenoses of the common trunk of the left coronary artery at the root of unstable angina?].

In a series of 200 cases of unstable angina who have had coronary arteriography carried out, a stenosis of more than 60% of the trunk of the left coronary artery was noted in 40 cases (20%). This sinister site of arteriosclerosis may be suspected in patients presenting with long-standing angina (mean for the group 44 months), an angina which has recently become worse, one which is not responding rapidly to rest and beta-blockers, and in particular one where there has been a previous infarction (50% of cases). Coronary arteriography shows that the lesions were more diffuse and more severe in the group with stenosis of the main trunk.
