[Delayed angioplasty of residual coronary stenosis after thrombolysis of myocardial infarction: prognostic factors of left ventricular function].

The aim of this study was to analyse the prognostic factors of long term left ventricular function after successful delayed angioplasty of residual coronary stenosis after thrombolysis for myocardial infarction. The left ventricular function of fifty patients, aged 54 +/- 10 years, who underwent intravenous thrombolysis 2.9 +/- 1.

[Coronary angioplasty and electric alternans of the ST segment].

Alternans of the ST segment is a rare phenomenon during coronary angioplasty. The authors report three cases. It is usually observed in left anterior descending arteries without collateral circulation.

[Left ventricular function and secondary angioplasty after anterior infarction in simple coronary vessel disease].

Arterial patency is a good prognostic factor in terms of survival and left ventricular function after myocardial infarction. The aim of this prospective study was to evaluate the benefit of secondary angioplasty of the infarct-related artery in single vessel, left anterior descending disease, on regional and global left ventricular function. Initial coronary angiography was undertaken at the 7th +/- 2 days after the onset of infarction.

[Spontaneous and isolated dissection of the coronary arteries, apropos of 8 cases with favourable outcome].

Spontaneous coronary artery dissection is rare compared with the high incidence of atheromatous coronary artery disease. Eight new clinical and angiographic cases diagnosed between 1984 and 1990 are reported. The patients were 6 men and 2 women with an average age of 44.

[Infectious endocarditis on permanent endocavitary pacemakers: value of echocardiography and review of the literature].

Infectious endocarditis around indwelling pacemakers is rare (0.15% of all implantations). They have a gloomy prognosis with a global mortality rate of nearly 34% as emerges from this review of the literature concerning 58 cases of infectious endocarditis published within the past 16 years.
