GABAergic and glutaminergic modulation of centrally evoked arrhythmias in rats.

A standard electrical stimulus applied to the posterior hypothalamus evoked cardiac arrhythmogenic responses in the spontaneously hypertensive rat. Isolated premature ventricular beats or doublets and nonsustained ventricular tachycardic salvos were observed. This effect was associated with a large rise in blood pressure (79 +/- 3 mm Hg).

[Predictive factors of survival after mitral valvuloplasty].

Survival and freedom from reoperation following mitral valvuloplasty (MV) was evaluated in 54 patients (pts) between October 1973 and December 1992. Ages of 35 men and 19 women averaged 49 years (+/- sd:18 yrs). Preoperative NYHA class was II or III in 48 patients (89%) and class IV in 6 pts.

Bronchial carcinoids: long-term prognostic factors.

Between 1962 and 1987 bronchial carcinoids were diagnosed in 41 patients (21 men, 20 women) at l'Hôpital du Sacré-Coeur and the Centre hospitalier Maisonneuve-Rosemont. The patients ranged in age from 19 to 73 years (mean 47 years). Fourteen of the 19 asymptomatic carcinoids were discovered on routine chest radiography.

[In situ femoro-popliteal bypass grafts. Study of 85 cases using Cartier's technique].

From January 1985 to december 1989, 83 patients (69 men, 14 women) underwent an in situ femoro-popliteal bypass using a semi-closed technique and the valvulotome developed by Dr Paul Cartier. Most patients (67%) were operated for severe ischemia while 33% were for claudication. HTA was present in 31% of patients, diabetes in 38% and CAD in 57%.
