[Intra-arterial thrombolysis of a basilar vascular accident during coronary angiography]. / Thrombolyse intra-artérielle d'un accident vasculaire basilaire au cours de la coronarographie.

The authors report the case of a 67 year old man with a previous history of aortobifemoral arterial graft who had unstable angina after carotid endarterectomy. Coronary angiography by the right brachial artery was complicated by a cerebrovascular accident with a reactive coma, convulsions and respiratory problems. Selective angiography of the right vertebral artery showed an image of occlusive thrombosis of the basilar artery. In view of the clinical state and angiographic appearances, the authors decided on immediate intra-arterial thrombolysis with Urokinase which dissolved the clot and reestablished flow in the basilar artery, the cerebellar and posterior cerebral arteries. The outcome was favourable with immediate and good recovery of consciousness and hospital discharge on the sixth day without neurological or radiological sequellae. Cerebrovascular accident is a rare and potentially serious complication of left heart catheterisation which requires immediate cerebral angiography to determine the mechanism and propose an appropriate therapeutic approach.

[Characteristics and influence of different clinical forms on the development and prognosis of carotid sinus syndrome. Apropos of 215 cases]. / Caractéristiques et influence des différentes formes cliniques sur l'évolution et le pronostic des syndromes du sinus carotidien. A propos de 215 cas.

The carotid sinus syndrome is a well-known cause of syncope: the cardio-inhibitory forms are the easiest to diagnose and probably the easiest to treat. However, the vasodepressive forms are as common but their outcome is mainly unknown. Eight hundred and fifty-three patients underwent endocavitary electrophysiological studies with invasive blood pressure measurement for unexplained syncope between October 1984 and January 1990. A carotid sinus syndrome was diagnosed in 215 cases. Fifty-two patients (24.2%) had a cardio-inhibitory form (ventricular standstill > or = 3 s during carotid sinus massage), 40 (18.6%) had a pure vasodepressive form (isolated fall of systolic blood pressure > 50 mmHg during massage) and 123 patients (57.2%) had a mixed form. The average age was 74.1 +/- 9.7 years with no difference between the different forms. A number of parameters was different on the cardio-inhibitory and vasodepressive forms: the number of men (75.6 vas 24.4%; p < 0.05) and the number of syncopes (83.3 vs 60%; p < 0.02) were greater in the cardio-inhibitory form; the vasodepressive forms were more often associated with a history of transient ischaemic attacks (15 vs 0%), a poor cardiovascular status (hypertension: 47.5 vs 15.7%; p < 0.01), coronary artery disease (47.5 vs 25.5%; p < 0.05), cardiac failure (27.5 vs 11.7%; p < 0.05), induction of sustained supraventricular tachycardia (50 vs 23.5%; p < 0.05) and a greater pacemaker effect (53.6 vs 34.8 mmHg; p < 0.01); of the 191 patients (84.9% of the population) followed up for an average of 21.2 months, 168 received treatment: implantation of a cardiac pacemaker in 108 patients, reduction of antihypertensive and/or potentially bradycardia-inducing drugs in 30 patients, prescription of antiarrhythmic therapy, in 30 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[Value of intravenous flecainide in electro-induced supraventricular arrhythmia. Apropos of 37 cases]. / Intérêt du flécaïnide en intraveineuse dans les troubles du rhythme supraventriculaires électro-déclenchés. A propos de 37 observations.

Thirty-seven patients presenting with electro-induced supraventricular arrhythmia sustained for more than 10 min or symptomatic received an intravenous injection of flecainide acetate (1.5 mg/kg; 10 mg/min). There were 24 cases of atrial fibrillation, 13 of atrial tachysystole with more than 180 beats per minute. Electrophysiological exploration was carried out for syncope (13 cases), lipothymia with palpitations (11 cases) or without palpitations (8 cases), or for a stroke of unknown origin. The induced arrhythmia was the only electrophysiological abnormality in 57% of cases. A return of sinus rhythm was obtained in 70% of cases during the injection (12 cases) or shortly after the end of the injection (14 patients). Safety was good, with the exception of the onset of two junctional rhythms and one case of non-syncopal monomorphic ventricular tachycardia. After an initial reduction, the PR, QRS, PA and HV intervals were significantly longer than baseline, whereas the AH space and the systolic blood pressure remained virtually unchanged. Thus the provision of IV flecainide acetate can only be beneficial in carrying out study protocols of abnormalities of the atrial substrate.

[Myocardial infarction in patients aged 70 years and over]. / Infarctus du myocarde chez les sujets âgés de 70 ans et plus.

109 subjects aged 70 years (58 women, 51 men; average age 77 years) were hospitalized in the CICU (Cardiology Intensive Care Unit) over the period stretching from 1984 to 1986. The average length of stay in the CICU was 1 week, completed by an average stay of 5 days in the cardiology department. 100 per cent of the patients were followed up. Of the clinical parameters made evident by this study, the authors note that hypertension was the predominant risk factor (52.2 per cent); a history of coronary disease was noted in 60.5 per cent; 26.6 per cent of the patients were hospitalized before the 6th hour, chest pain being typical in 78 per cent versus painless in 11 per cent of patients; topographically, the infarction was anterior in 55 per cent, posterior in 40.4 per cent, and around the circumference in 4.6 per cent of cases; 80.8 per cent of the infarctions were transmural versus 19.2 per cent of infarctions without the Q wave--the latter accounted for a higher hospital mortality rate (38 per cent versus 27.3 per cent). The main complications were disturbances in rhythm (60.6 per cent) and LVI (56.9 per cent). Complications on the form of infections were noted in 15.6 per cent. Apart from the usual indicators of severity (cardiogenic shock, VF, LVI), infarction of the RV and AF had a serious effect on the prognosis. latrogenic disease accounted for 18.9 per cent. From the point of view of prognosis, hospital mortality was 30 per cent; mortality after one year was 44 per cent and 47.7 per cent after 2 years (in a group of 76 subjects).(ABSTRACT TRUNCATED AT 250 WORDS)

[Spondylodiscitis disclosing bacterial endocarditis. Apropos of a case. Review of the literature]. / Spondylodiscite révélatrice d'une endocardite bactérienne. A propos d'une observation. Revue de la littérature.

The authors report a case of infectious spondylodiscitis revealing a staphylococcal endocarditis in a patient with a Carpentier aortic heterograft. This case, along with 60 descriptions from the literature, has enabled them to specify the characteristics of occurrence of endocarditis during a spondylodiscitis. The clinical factors in favor of this association are: a pre-existing cardiopathy, an oral port of entry, occurrence of other rheumatoid manifestations, even more the presence of complications of endocarditis. The laboratory factors in favor of an association are: discovery of an inflammatory anemia, of circulating immune complexes, of a cryoglobulinemia, of a rheumatoid factor, of hematuria. But it is mostly the demonstration of streptococcus in blood cultures and other samples that should be an indication to search for an endocarditis, the course of which dominates the prognosis.

[Carotid sinus syndrome. Contribution of arterial pressure monitoring to intracavitary electrophysiological exploration]. / Le syndrome du sinus carotidien. Apport de la monitorisation de la pression artérielle à l'exploration électrophysiologique endocavitaire.

A prospective study based on intracavitary electrophysiological exploration coupled with invasive arterial pressure monitoring was conducted in 245 patients aged 70.2 +/- 13 years who had experienced syncopes and/or lipothymias of uncertain origin. The study showed that 63 patients (25.7 p. 100) had carotid sinus syndrome (CSS). The syndrome was of the vagal type (cardiac inhibition) in 27 p. 100 of the cases, of the depressor type (vasodepression) in 22 p. 100 of the cases and mixed in 51 p. 100 of the cases with the two types of pathological response: electrophysiological and haemodynamic. Compared with the remaining 182 patients, these 63 patients were more frequently male (63.5 p. 100, p less than 0.01), of the same age (71.7 years, NS) and more symptomatic, meaning that syncopes occurred in 80 p. 100 of the cases and that their number per patient was higher (2.92, p less than 0.01). A predisposing factor (usually a vagal predominance) was found in 26.9 p. 100 of the cases. In 30 p. 100 of the patients CSS was associated with a sinus node disease or with disorders of atrioventricular conduction. Another haemodynamic abnormality often associated with CSS was a more pronounced (-38.7 mmHg, p less than 0.01) and more frequent (68 p. 100, p less than 0.01) pacemaker effect. 62 p. 100 of patients with mixed CSS had an increase in systolic arterial pressure during vagogenic manoeuvres with DDD mode stimulation as compared with the VVI mode stimulation.(ABSTRACT TRUNCATED AT 250 WORDS)

[Primary liposarcoma of the left atrium surgically treated]. / Liposarcome primitif de l'oreillette gauche opéré.

A case of myxoid liposarcoma of the left atrium in a 35-year old man is reported. The tumour, revealed by an atrial flutter, was excised. The patient died 13 months later, with multiple metastases. A review of the literature yielded only 7 cases of primary liposarcoma of the heart, including 4 which were surgically treated. This confirms the extreme rarity of a tumour which has a very poor prognosis due to recurrence in situ or metastatic spread.

[Infectious endocarditis caused by rare germs. Review of the literature apropos of 2 cases]. / Les endocardites infectieuses à germes rares. Revue de la littérature à propos de deux observations.

The authors report two new cases of endocarditis secondary to exceptionnally encountered germs: one to Pasteurella pneumotropica, the other ascribed to Leptospira ictero-haemorragiae, on serologic criteria. Concerning these two cases, they propose to take a census of rare germs, from a detailed study of the literature. Among more than 5,000 cases of endocarditis published after 1944, are considered as rare germs those causing a disease in less than one p. cent of the cases. This purely "mathematical" definition enable to include 45 germs. A synthesis of all the cases reported attempts to demonstrate a few particular traits of these endocardites secondary to rare germs.

[Iatrogenic pathology in coronary intensive care units. Results of a prospective survey on 802 patients]. / La pathologie iatrogénique en unité de soins intensifs cardiologiques. Résultats d'une enquête prospective sur 802 patients.

Iatrogenic disease in the coronary care unit was detected and analysed using a grid over a 17.5 month period (16.09.82 to 25.02.84). The cases of 802 patients, mean age 65.8 years, predominantly male (56.6%) were examined. Minor or minimal pathology in which the causal relationship was conditional or doubtful according to Karch's criteria was excluded. Only those conditions, moderate, severe or even lethal, specific or not to this type of unit, requiring specialised hospital care and in which the causal relationship could be adequately established were retained. Iatrogenic pathology was common: 11.84% of admissions. This group of 95 patients did not differ significantly from a control group with respect to age [average 4 years older (NS)] or mortality. However, there was a clear cut female predominance (68%, p. less than 0.01) and a different distribution of the organic pathology (p less than 0.001). The iatrogenic disease developed before hospital admission in 40% of patients and during hospitalisation in 60% of patients. It increased the duration of the patient's stay by half (2.77 days). Nearly a quarter of these patients had two or more types of iatrogenic disease. The undesirable effects of drugs were mainly bradycardia (44 cases), tachycardia (11 cases), haemodynamic changes, vascular, renal, gastrointestinal, metabolic and endocrine complications. Twenty-one complications of medical procedures and 13 of surgical procedures were also noted. This study, the first to have been performed in a Coronary Care Unit to the author's knowledge, confirms the high incidence of iatrogenic pathology. This fact should be born in mind before taking any therapeutic decision or before performing invasive diagnostic investigations.

[Congestive cardiomyopathy in addiction to clobenzorex, an anorexigenic drug]. / Cardiomyopathie congestive au cours d'une toxicomanie à un anorexigène, le clobenzorex.

Cardiac failure caused by high doses of amphetamine-like drugs is rare. We report a case of decompensated congestive cardiomyopathy occurring in a 29 year old woman addicted to clobenzorex (Dinintel). This patient had been taking 5 to 7 capsules per day for 5 years. No other cause of cardiac failure was detected. A rapid improvement was obtained by digitalis and diuretic therapy; no further episodes of cardiac failure were observed after one year. However, the drug could not be completely withdrawn and echocardiography has shown increasing left ventricular dilatation. The possible mechanisms of amphetamine induced myocardial toxicity are discussed and the analogy with the group of adrenergic cardiomyopathies is underlined.

Predictive value of atrial pacing test for survival of patients with coronary artery disease.

There is evidence that patients with signs of poor left ventricular function or marked ischemia at low work load during an exercise test have a poor prognosis for survival. To determine whether a pacing test can provide similar information, the 6-yr survival rate was computed in 118 medically-treated patients who had undergone a standardized atrial pacing test. Among the 118 patients, 80 had significant coronary artery disease (CAD). The variables measured for the atrial pacing test were: induced angina, myocardial lactate extraction (MLE), maximal heart rate (MHR) and left ventricular end-diastolic pressure (LVEDP) changes. There was no death in 38 patients without significant CAD. The 6-yr survival rate of the 80 patients with CAD was 84 +/- 4% (+/- SEM). Of all the variables, the combinations of MHR less than or equal to 150 beats min-1 during pacing associated with a LVEDP increase greater than or equal to 5 mmHg immediately after pacing or with MLE less than or equal to 0% during pacing constituted the best predictors. Patients with a MHR less than or equal to 150 beats min-1 and a LVEDP increase greater than or equal to 5 mmHg had a 6-yr survival of 56 +/- 12% in comparison to 92 +/- 3% for the remaining patients (P less than 0.001). Patients with a MHR less than or equal to 150 beats min-1 and MLE less than or equal to 0% during pacing had a 6-yr survival of 64 +/- 11% in comparison to 91 +/- 4% for the remaining patients (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
