[Anesthesia for carotid surgery with clamping under residual carotid pressure control].

Carotid endarterectomy with clamping is performed in 50 patients. Internal carotid artery stump pressure is measured in all cases after clamping at the beginning of the operation. In 35 patients, an increase of systolic pressure is observed which allows a stump pressure more than 70 mmHg in 29 patients. In 15 patients, systolic pressure decreases and a stump pressure more than 70 mmHg is observed in two patients. When the stump pressure is more than 70 mmHg, the clamping is maintained. When the stump pressure is low, the clamping is stopped. A perfusion of Metaraminol increases systolic pressure in all cases: stump pressure is measured again after a second clamping. In 17 cases out of 19, stump pressure increases more than 70 mmHg and the clamping is maintained. In the two cases with a low stump pressure, a shunt is used during intervention.

Long-term results of permanent atrioventricular sequential demand pacing.

Pervenous atrioventricular sequential demand pacemakers (AVSDPs) were implanted in 18 patients using an atrial electrode positioned in the right atrial appendage and a ventricular electrode positioned at the apex of the right ventricle. The indications included 13 patients with the sick sinus syndrome (72%), five of whom had the tachycardia-bradycardia syndrome, three with paroxysmal supraventricular tachycardia, one with cardiomyopathy and one with carotid sinus syncope. The follow-up ranged from 6 to 38 months, with a mean of 19.4 months (a total of 350 pacing months). Seventeen patients (94%) are asymptomatic. One patient had persistent episodes of paroxysmal supraventricular tachycardia. In the remaining patients with tachyarrhythmia, pacing alone (three patients) or in combination with antiarrhythmic drugs (four patients) controlled the tachyarrhythmia. There was one displacement of the atrial electrode (5.5%). Extrusion of the pacer occurred in three patients. It is concluded from this experience that AV sequential pacing is an effective technique and may be useful in patients with sick sinus syndrome, in patients with tachyarrhythmia and/or patients with poor myocardial function. However, continued research is needed to prolong battery life and to reduce the size of the pacemaker.

[Left ventricular aneurysms. Hemodynamic studies and surgical results].

The cardiac function of 37 cases of ventricular dyskinesia were studied by cineangiography. The amplitude and speed of contraction of the contracting parts was evaluated as well as the volume of the akinetic zone. A score of coronary artery obstruction was made for those patients who underwent coronary arteriography. All the patients had resection of their aneurysm. Four patients died in the immediate post-operative period. Six patients developed a temporary low output state requiring circulatory assistance. Twenty-seven patients were operated on successfully without posing any haemodynamic problem. Good immediate and late post-operative results were associated with an ejection fraction of the contracting part greated than 0,40, a dyskinetic area less than 40% and a coronary artery obstruction index of less than 6. Resection of the aneurysm, sometimes associated with aorto-coronary bypass grafting (5 cases), led to a marked improvement in heart failure and/or disappearance of ventricular arrhythmias.

[Reintervention after valve replacement surgery. Study of 358 cases].

There is still a place for conservative surgery in valvular disease of the heart to the extent that artificial prostheses have not yet been perfected sufficiently for them to be regarded as the method of choice. While these conservative operations are rarely applicable to the aortic valve, techniques such as Carpentier's ring occupy an important place in the treatment armamentarium for disorders of the mitral valve, and even more so of the tricuspid valve.

[Valve protheses and anti-vitamin K. Biological study in patients given weak and strong doses of anticoagulants].

57 patients with Björk aortic valves had an in-depth study of their coagulation carried out. It seems that the well-anticoagulated group (39 patients) had more marked haemolysis, had a higher mean level of fibrinogen and PDF, but less biological signs of activation of fibrinolysis than the group who were non- or mildly-anticoagulated (18 patients). The increased platelet aggregation, which is often noted, was correlated with the signs of haemolysis, or of activation of the breakdown of fibrinogen. Apart from the problem of haemolysis, anticoagulant treatment appears biologically to be a moderating factor in the activation of the breakdown of fibrinogen and, by this means, of the utilisation of clotting factors.
