[Compression of the right pulmonary artery by a dissecting aneurysm of the ascending aorta. Apropos of a case occurring long after aortic valve replacement].

The authors report the case of a dissecting aneurysm of the ascending aorta compressing the right pulmonary artery in a 62 year old man, 6 years after aortic valve replacement. The clinical presentation was that of pulmonary embolism. The diagnosis was confirmed by angiopneumography and CT scanning. The ascending aorta was successfully replaced with a Dacron prosthesis. One other case was found in a review of the literature. After discussing the predisposing factors of aortic dissection during cardiac surgery, the authors underline the diagnostic value of CT scanning in cases of suspected aneurysms of the thoracic aorta.

[Ambulatory recording of blood pressure. Study of the reproducibility of findings in 25 subjects].

The reproducibility of a novel ambulatory blood pressure (B.P.) monitoring was tested, for clinical trial in hypertension. The spacelabs apparatus is based on standard auscultatory and oscillometric blood pressure measurements. Ten normotensive patients and 15 hypertensive patients were investigated as follows: their blood pressure was monitored twice over a 24 hr period at an interval of 30 and 15 days respectively. The monitoring data were expressed as the mean of the average blood pressure over day-time (7 hr-22 hr) and 24 hr as well as 24 hr. B.P. profiles (means of 4 measurements per hour). The statistical analysis of the two subpopulations of patients showed a satisfaction reproducibility of both the 24 hr B.P. curves (normotensive patients: PAS: r = 0.94; PAD: r = 0.92; Hypertensive patients PAS: r = 0.82; PAD: r = 0.64 p less than 0.001). and blood pressure levels (normotensive patients: J1: 113 +/- 10/70 +/- 6 mmHg; J30: 110 +/- 10/68 +/- 6 mmHg. Hypertensive patients: J1: 150 +/- 10/98 +/- 9 mmHg; J15: 155 +/- 15/96 +/- 8 mmHg). In contrast, analyzing each patient individually exhibited a correct reproducibility of the B.P. levels but the 24 hr--profiles of either the diastolic or systolic blood pressure could not be correlated with sufficient reliability (normotensive patients: 7 times out of 10 for PAS, and 4 times out of 10 for PAD; hypertensive patients: 5 times out of 15 for PAS, and 3 times out of 15 for PAD). In addition, the patient activity, should be carefully controlled during ambulatory blood pressure measurements.(ABSTRACT TRUNCATED AT 250 WORDS)

[Compression of the right pulmonary artery by a dissecting aneurysm of the ascending aorta. Value of x-ray computed tomography].

Right pulmonary artery compression by a dissecting aortic aneurysm-value of computed tomography. The authors relate a case of dissecting aortic aneurysm occurring as a late complication of aortic valve replacement and causing right pulmonary artery compression. Computed tomography appears to be performing technique for the exploration of this unusual case.

Effects of hyperthermia on normal or neoplastic rat liver.

An experimental study was conducted in rats to evaluate the sensitivity of the liver to infrared hyperthermia. A 15-min hyperthermia session treating only the liver was done in rats with a normal hepatic parenchyma and in rats with hepatocarcinoma induced by chronic 3'-diethylaminoazobenzene intoxication, at various ranges of intrahepatic temperature. In normal rats, 40-42 degrees C hyperthermia was well tolerated, but the mortality rate increased when the intrahepatic temperature exceeded 42 degrees C. In rats with tumors, a 40-42 degrees C hyperthermia session was well tolerated in case of small tumors, but resulted in a high mortality rate in case of large tumors. In all cases, death occurred as a consequence of liver injury. This study using a simple method of hyperthermia defines the thermosensitivity of the neoplastic or normal rat liver and provides a basis for further investigations on the effect of hyperthermia on experimental liver tumors.

[Automatic non-ambulatory measurement of arterial pressure. Computer data-analysis of the evaluation of antihypertensive treatment].

To gain a better understanding of the therapeutic effect of HTA, the present study reports a new method essentially based on the non invasive non ambulatory monitoring of blood pressure by the Dinamap 845. This apparatus was initially assayed towards the measure of invasive blood pressure and by the auscultatory method, and afterwards towards the analysis of approximately one hundred resulting data. The computer analysis of the data was performed using a microcomputer which gives the results as: time dependent curves over 24 hr; histograms, percentage of the values of HTA (above 140 mmHg for the systolic and 90 mmHg for the diastolic one); numeric data such as: average values, SEM... The method reported here appears to be convenient to follow new therapeutic treatment because the data obtained before and after treatment proved to be more rigorous and less varying upon the physician. This kind of investigation seems also helpful in the case of both hypertensive emergencies and treatment of those HTA which are difficult to stabilize. But it is thought to be not easily applied to all the hypertensions studied in the usual medical practise.

[Carotid sinus syndrome. Apropos of 6 cases with the cardio-inhibitory type].

The hyperirritable carotid sinus syndrome may have three different expressions: 1. a prolonged ventricular pause, the cardioinhibitory type and the most common; 2. hypotension without slowing of the heart rate, the vasodepressor type; 3. the association of a prolonged ventricular pause and hypotension, the mixed type. The aim of this communication is to present 6 cases of the cardioinhibitory type of hyperirritable carotid sinus syndrome. Three cases were selected from a series of 242 patients investigated for syncopal episodes. The results of carotid sinus massage and electrophysiological investigation could be classified into 4 goups: --Carotid sinus massage reproducing the clinical symptoms negative electrophysiological investigation: pure carotid sinus syndrome. --Carotid sinus massage negative, electrophysiological investigations negative: pure hyperirritable carotid sinus syndrome. --Carotid sinus massage reproducing the clinical symptoms, electrophysiological investigation positive: associated carotid sinus syndromes. --Carotid sinus massage negative: electrophysiological investigations positive: associated hyperirritable carotid sinus syndrome. The diagnosis of the cardioinhibitory type of hyperirritable carotid sinus syndrome was made on four criteria: 1. the association of hyperirritable carotid sinus and spontaneous syncopal or minor syncopal episodes; 2. the reproduction of symptoms together with a ventricular pause of over three seconds by carotid sinus massage under cover of pacing (to exclude the rare mixed forms); 4. the absence of associated sinus node dysfunction or atrioventricular conduction defects on endocavitary electrophysiological recordings. This syndrome should be tested for as a routine in patients with syncope as usually no suggestive trigger factors are found. Carotid sinus massage in this series of patients caused quite long ventricular pauses (average: 7,5 sec.) with serious symptoms (2 syncopes). Therefore, in the investigation of patients with syncope it would seem to be useful to perform this manoeuvre during electrophysiological investigation with pacing cover. The treatment of choice of the cardioinhibitory carotid sinus syndrome is permanent pacing. This was undertaken in 5 out of four 6 patients leading to total regression of all symptoms. It seems justifiable to propose permanent pacing for patients who have syncope with hyperirritable carotid sinus syndrome, easily demonstrated by carotid sinus massage, but in whom massage does not provoke symptoms, reasoning by analogy with patients with atrioventricular conduction defects or sinus node dysfunction.

[Electrocardiogram after complete repair of tetralogy of Fallot].

207 cases of Fallot's tetralogy having undergone complete surgical correction have been studied in this work as regards the electrocardiographic changes induced by surgery. The observed anomalies were the following: --Intraventricular conduction disturbances --179 cases (86,5%) --Atrio-ventricular block --33 cases (16%) --Arrhythmias --29 cases (14%) --Myocardial infarction patterns --6 cases (2.9%). In the atrioventricular conduction disturbances, right complete bundle-branchblock was most frequently observed (126 cases, 70.4%). In 22 cases, it was combined with left anterior hemiblock, the onset of which seemed to be favoured by the previous existence of a minor left anterior hemiblock. Of the 33 cases of atrio-ventricular block which started during operation or immediately afterwards, 13 will remain permanent, 10 of which were of a high degree, requiring implantation of an intracorporeal pacemaker in 8 cases. No case of block started later on, the cases of delayed block being in fact recurrences of transient blocks which had appeared during or immediately after the operation. The candidates to sudden death by paroxysmal block are therefore patients who had a transient block during of following operation, especially if they had besides bilateral bundle-branch block. The arrhythmias were on the whole devoid of danger. 6 cases of myocardial infarction (2.9%) were observed; their incidence is therefore not negligible.
