[Behcet disease: uncommon cause of myocardial infarction].

A 25-year-old man who was known to have Behçet's syndrome and who has no coronary risk factors suffered an acute anterior wall myocardial infarction which was complicated by a ventricular fibrillation. The diagnosis of Behçet's syndrome was based on recurrent thrombophlebitis, genital and oral aphtoses, posterior uveitis, positive pathergy test and HLAB51. About 20 cases of myocardial infarction were reported in the literature but the etiopathogeny, the causal relationship and the treatment are yet unknown.

[Correlation between aortic atherosclerosis at transesophageal echocardiography and coronary atherosclerosis].

The aim of this study was to test the relationship between atherosclerotic plaques in the thoracic aorta detected by transesophageal echocardiography and coronary artery disease detected by angiography. A prospective study was carried out in 103 patients who underwent coronary angiography. All patients underwent transesophageal echocardiography with imaging of the thoracic aorta. Aortic intimal changes were classified in 4 grades. The detection of aortic atheroma plaques was the strongest predictor of coronary artery disease. The presence of aortic plaques on transesophageal study had a sensitivity of 97.6% and a specificity of 80% for angiographically proved obstructive coronary artery disease. The positive predictive value of aortic plaque for obstructive coronary artery disease was 95.3% and the negative predictive value was 88.9%. Compared to the other segments, the detection of atherosclerotic plaque in the descending aorta has the highest sensitivity but the specificity was the highest in the ascending aorta. With older age and in women the specificity decreased, while the sensitivity increased.

[Endocavitary implantation of a permanent pacemaker in the contralateral side of right pneumonectomy: a case report].

The definitive endocardial stimulation is easy to install, allows a stable position of the leads, and a satisfactory stimulation thresholds for a long period. The epicardial approach is reserved for some rare indications including infectious contexts. The endocardial approach has been considered for a 67 years man with a complete AV block and an atrial fibrillation. This patient had undergone a right pneumonectomy 15 years before. A VVIR pacemaker has been implanted successfully by an internal jugular vein approach, and connected to a passively fixed unipolar lead. Because of the right ventricle deformation which made it unrecognizable, even by angiography means, we had to face major difficulties to position the lead. The epicardial approach should be considered even if a direct unique lung controlateral approach is easier than homolateral, because it allows us a quick ventricular access under the view control.

[Mitral stenosis secondary to Hurler's syndrome].

Valvular disease in mucopolysaccharidosis type I-Hurler (MPS/1H) is relatively common, but mitral stenosis is very rare in this genetic abnormality. The authors describe the case of a 16-year old girl with Hurler's syndrome diagnosed at 4 years of age. The morphological features were characteristic: bridged nose, thickened lips, macroglassia, short neck (gargoylism, short, thick fingers and limitation of brachial and fore-arm flexion. She presented with stage II dyspnoea and paroxysmal nocturnal dyspnoea. Radiological and echocardiographic studies revealed severe mitral stenosis with haemodynamic complications requiring mitral valve replacement. Anatomopathological analysis of the mitral valve confirmed mucopolysaccharide deposits as the cause of this particular case of mitral stenosis.

[Assessment of pure isolated mitral valve insufficiency by Doppler echocardiography].

Taking 33 patients having pure MI as a material, the authors find a correlation between regurgitation fraction obtained by calculation of outputs estimated by Touch's method and angiographic values. There is a statistically significant differences (P < 0.001) between regurgitation fraction of grade I to II and grade II to III MI. The ratio mitral integral time velocity (ITV) to Aortic (ITV) is an important semi-quantitative assessment of pure MI. In fact, a ratio > 1.3 identify important degree of MI with 82% sensitivity and 93% specificity. The authors estimate that there is a correlation between the ratio of regurgitant jet surface to left atrial surface found in TEE and their degree of MI in angiography with a significant difference (P < 0.001) between the ratio of grade I to II and grade II to III MI in angiography. A ratio higher than 40% allow to identify grade III MI at minimum.

[Atrial fibrillation].

The aim of transesophageal echocardiography (TOE) in atrial fibrillation milieu is to search a cardiac chamber thrombus. In order to establish the indications of TOE and to raise new issues for the echographic prognosis of maintain of sinus rhythm, 40 patients with atrial fibrillation who underwent cardioversion were prospectively screened. All patients had transthoracic and transesophageal echocardiography before procedure to control the absence or disappearing of atrial thrombus (N = 7). All 40 patients underwent a successful cardioversion. Follow-up was done after one, three and six months for both success group (N = 28) and refibrillation group (N = 12). Our study provides evidence that the only predictive echographic factor of maintain of a good result (sinus rhythm) after cardioversion was a systolic velocity peak > 0.25 metir/sec.

[Place of definitive cardiac stimulation in cardiomyopathies and atrial arrhythmia].

Definitive cardiac stimulation ralatually used for brady cardia are going to be in the third millennium the specific therapy of arrhythmia and cardiomyopathy. In the last 10 years, may progress occur in the use of cardiac stimulation as hemodynamic therapy of obstructions hypertrophic and dilated cardiomyopathies resistant to conventional medical treatment. Moreover auricular stimulation present antiarrhythmic effects in some atrial arrhythmias as auricular fibrillations auricular diseases and atypical flutters. It confirmed by prospective multicentric randomized trials cardiac stimulation may represent in the future a good physiopathologic and efficient treatment free from the side effects of drugs that remain partially active. These perspectives needs to be modulated by the known and acceptable risks of a definitive cardiac stimulation.

[Infectious enterococcal endocarditis associated with Laubry and Pezzi syndrome].

Laubry and Pezzi syndrome is a rare but serious complication of ventricular septal defect that increase the infectious endocarditis risk. Authors report a case of an 18 years old young girl presenting an enterococcus infectious endocarditis associated to Laubry and Pezzi syndrome. Initial course is not favourable requiring a surgical treatment in the acute stage. Bacterial endocarditis combined with Laubry and Pezzi syndrome have a poor prognosis needing observation and strict preventive precautions when a favoring factor is present.

[Dilated cardiomyopathy secondary to acromegaly].

In acromegaly, dilated cardiomyopathy is rare. Indeed, arterial hypertension, coronary artery disease and hypertrophic cardiomyopathy are more common. The authors report a case of a 42-years-old man with dyspnea (class III NYHA) and palpitations. The cardiac echography showed a dilated cardiomyopathy. The investigations revealed an acromegaly as an etiology. Diagnosis was based on patient morphotype, a high level of growth hormone (GH) and a pituitary adenoma detected by magnetic resonance imagery. This case is characterized by the absence of arterial hypertension and hypertrophic cardiomyopathy. The coronary angiography was normal. Consequently, in this particular case, dilated cardiomyopathy seems specific to acromegaly.

[Right mid-ventricular stenosis with intact interventricular septum].

Pure infundibular stenosis of the right ventricle is a rare congenital anomaly. Right midventricular stenosis with intact interventricular septum is even rarer. It consists of obstruction of the trabecular zone of the right ventricle by a hypertrophied moderator band with or without abnormal muscle bundles. This anomaly can now be diagnosed by transthoracic echocardiography, while haemodynamic and angiographic diagnosis is reserved for doubtful cases. Two cases of midventricular stenosis are reported. In both patients, the diagnosis was suspected bu ultrasonography which showed a right intraventricular gradient of about 80 mmHg without identifying the exact site (infundibular or midventricular). The diagnosis was corrected by the operative findings. A good postoperative course was observed for both patients.

[Preventive treatment using laser of age-related macular degeneration of the contralateral eye after age-related macular degeneration of the first eye].

Since 1982, and with informed patient consent, we have photocoagulated confluent drusen and limited serous pigment epithelium detachment (SPED) in the fellow eye of ten patients suffering from advanced, disciform type, age-related macula degeneration (ARMD). This treatment was only carried out on appearance of metamorphopsia. Photocoagulation was performed with either the green ray of the argon laser, or the yellow ray of a dye laser. Spots of about 200 microns were placed in a grid-like fashion among the drusen. No complications were observed due to the treatment. The follow-up period on these ten patients, eight women and two men, mean age 77 years, was two to eight years, and the three patients have died. The drusen disappeared completely in three patients and partially in one. The functional results seemed favorable in three cases. In one case of confluent drusen associated with SPED and serous retinal detachment, vision improved remarkably from 0.3 to 0.5 with a Parinaud 2, with a follow-up of five years. In another case, the improvement was from 0.4 to 0.7 but the patient died after only a few months. In another case, vision has been stable for five years. The vision of the seven remaining patients deteriorated; three cases showed central areolar sclerosis, and one case a localised new vessel with vision less than 0.1. In three cases vision dropped to 0.2 and Parinaud 6, but they have been stable for at least four years (eight years for one patient).(ABSTRACT TRUNCATED AT 250 WORDS)
