[Cardiac hydatid cysts: report of 10 cases].

Authors report 10 observations of cardiac hydatid cyst collected to cardiovascular unit of Ibn Rochd hospital in Casablanca during last 7 years. Clinical investigation included in all cases chest X ray, ECG and ultrasonography (US). A computed tomography (CT) scan was performed in 6 cases, magnetic resonance imaging in four cases, transoesophageal US in two cases. Examination for other hydatic sites was realized in all cases, and brain CT was performed in 5 cases. The hydatid cyst was variably localized in the left ventricle in 6 cases, the pericardium in 4 cases, the interventricular septum in 2 cases, the right auricle in 2 cases and multiple locations in one case. The existence of other cardiac hydatid sites was found in 7 cases. Seven patients have been operated (2 cases to closed heart). Outcome was favorable in 6 cases with a mean of three years survey. Two patients died and 2 others have been lost of view. The diagnosis of the cardiac hydatid cyst has benefits from the combination USCT scan that allowed a precise topographical inventory, reducing the need for MRI to the complicated cases and to the rare cases of inconclusive results by US-CT scan.

[Echocardiographic assessment of cardiac remodeling in the high-level football player].

INTRODUCTION: The aim of this study is to assess the morphological and hemodynamic cardiovascular changes of 24 high-level football players, using Doppler-echocardiography, and compare them to a similar control group. METHODS AND RESULTS: Twenty-four elite football players were matched to 24 normal subjects according to age, sex, and body surface. All participants had a clinical examination, resting ECG, Doppler-echocardiography and a measurement of maximal oxygen uptake (VO2 max). The echocardiographic variables were compared between two groups by the Student's t-test and other statistical tests, using the SPSS 12 for Windows software. Compared to the control group, the wall thickness (10.49 + 1.04 vs. 7.5 + 2.04 mm, p < 0.05), the LV end-diastolic diameter (57.1 + 3.70 vs. 41.2 + 3.65 mm, p < 0.01) and left atrium surface (20.16 + 2.03 vs. 16.16 + 1.83 cm2, p < 0.01) were significantly more important in football players. The LV and RV ejection fractions were similar in both groups. The RV long-axis diastolic diameter (8 + 0.5 vs. 6.5 + 1.1 mm, p < 0.01) and S-wave using DTI (0.17 + 0.02 vs. 0.14 + 0.02, p < 0.05) were more important among football players. DISCUSSION: The hemodynamic and morphological changes result from an acquired cardiac adaptation in athletes with important endurance and resistive efforts. The majority of players presented an intermediate-type of remodeling, but the more offensive ones had an endurance-type heart, whereas the defense players had a resistance-type aspect. CONCLUSION: This study on the cardiac remodeling in high-level athletes permits to have a distinctive approach between physiological and pathological remodeling. This remodeling varies according to the player's post and exercise capacities. In a football player, a correlation between physical level and physical capacity is plausible.

[Cardiovascular abnormalities of the antiphospholipid antibody syndrome].

The antiphospholipid antibody syndrome (APS) may present with serious cardiovascular complications which should be recognised by the cardiologist. The authors report a series of 6 cases of APS diagnosed after thrombotic events and the finding of antiphospholipid antibodies. The APS was primary in 5 cases and associated with tuberculous lymphadenitis in 1 case. There was cardiac involvement in 5 patients with pericardial effusion in 3 cases, complicated by tamponade as the presenting sign of primary APS in the other 2, valvular disease in one case (moderate mitral stenosis with aortic valve disease) and pulmonary embolism in one case. Five patients developed recurrent deep vein thrombosis of the legs. One patient had a transient ischaemic cerebral attack.

[Hypertrophic cardiomyopathy disclosing Friedreich's disease. Report of a case].

The authors report the case of a 21 year old woman admitted to hospital for congestive cardiac failure due to concentric hypertrophic cardiomyopathy. Echocardiography showed severe systolo-diastolic left ventricular dysfunction without obstruction to ejection. Neurological examination showed a stato-kinetic cerebellar syndrome, a posterior radiculo-cordonal syndrome and a dysmorphic syndrome which characterise Friedreich's disease. In the light of this case and a review of the literature, the authors underline the rarity of cardiomyopathy in Friedreich's disease, its particular presentation and its poor prognostic significance in this disease.

Cardiac hydatid cyst revealed by complete heart block.

Hydatid cyst of the heart is an uncommon lesion. The infection is most common in sheep-raising areas of the world. We report a rare case of cardiac hydatid cyst revealed by complete heart block, which was removed with the patient under cardiopulmonary bypass. This case stresses the importance of echocardiography for the diagnosis of cardiac echinococcosis.

[Malignant mediastinal schwannoma in Recklinghausen's disease presenting as cardiac tamponade. Report of two cases].

The authors report two cases of Recklinghausen's disease admitted for cardiac tamponade. Two-dimensional echocardiography showed a pericardial tumour in addition to a compressive pericardial effusion. After pericardial drainage, the outcome was rapidly fatal. Histological examination confirmed the diagnosis of a malignant intrapericardial schwannoma. A review of the literature revealed the scarcity of mediastinal malignant schwannoma. Associated with Von Reckinghausen's disease in 2 to 13% of cases, the prognosis is poor. The presentation of malignant mediastinal schwannoma with cardiac tamponade remains very rare.

[Horton's disease presenting as a myocardial infarction].

The authors report the case of a 60-year-old man admitted for uncomplicated acute myocardial infarction. The history of persistent fronto-occipital headaches and palpation of bilateral tortuous temporal arteries with a decreased pulse suggested the diagnosis of temporal arteritis, particularly in the presence of marked laboratory signs of inflammation and the coronary angiograph findings. The diagnosis was confirmed by temporal artery biopsy. Treatment consisted of corticosteroid therapy, with a satisfactory outcome at three months. The diagnosis of temporal arteritis should be systematically suggested in patients over the age of 50 years, presenting with a marked inflammatory syndrome and recent-onset arterial disease. Similarly, any form of arterial disease occurring during treated temporal arteritis should initially be considered to be a secondary site of the arteritis, requiring intensification of corticosteroid therapy.

[Cardiac tamponade and transient ischemia revealing a syndrome of primary antiphospholipid antibodies].

The authors report a case of echocardiographically confirmed cardiac tamponade, which required emergency pericardial aspiration, and a transient ischaemic attack revealing an underlying primary antiphospholipid antibody syndrome in a 29-year-old patient. The test for antiphospholipid antibodies was positive on 2 occasions (IgG > 91.41 micrograms/l). The diagnosis of systemic lupus erythematosus was eliminated. A favourable course was observed after 3 months of corticosteroids and platelet antiaggregants. Any case of cardiac tamponade or transient ischaemic attack with an unexplained aetiology in a young patient must suggest the diagnosis of antiphospholipid antibody syndrome.

[Approach of Moroccan cardiologists to arterial hypertension].

The authors conducted a survey among 300 cardiologists in order to evaluate their knowledge of HT. Most of the 200 cardiologists answering the survey considered that systolic HT was defined by a systolic blood pressure greater than 160 mmHg (75%). Only 14 cardiologists (7%), defined systolic HT as a blood pressure greater than 140 mmHg. 121 cardiologists (60.5%) defined diastolic HT as a pressure greater than 95 mmHg. 2/3 of cardiologists were not familiar with the conclusions of the JNCV for the detection, evaluation and treatment of HT. All cardiologists agreed that treatment of HT should start with single-agent therapy. In the case of insufficient control, 11% doubled the dose, 5% changed the drug in the same class, 53% changed therapeutic category and 30% prescribed two-agent therapy. Once BP was stabilized, one half of cardiologists reviewed their patients once every 3 months, and 22.5% reviewed their patients once every six months. These results demonstrate that cardiologists do not correctly follow the rules of management of HT recently defined by the various working parties. The authors propose a number of points to remedy some of the deficiencies revealed by this survey.

Pericardial tamponade as the first manifestation of dermatopolymyositis.

Pericardial involvement in polymyositis and dermatomyositis (PM/DM) is rare, usually asymptomatic and exceptionally part of the initial presentation. We describe a 37-year-old patient hospitalized for overt acute pericarditis, revealing dermatomyositis, which to our knowledge has not been previously reported. Pericardial puncture relieved the patient. The pericardial fluid was citrine yellow, exsudative, and mainly contained lymphocytes. Search for LE cells and anti-DNA antibodies was negative, whereas the antinuclear antibodies and the rheumatoid factor were present in the pericardial fluid. A biopsy of the pericardium showed a non-specific chronic inflammatory state and the search for an etiology was negative. There was no sign of tuberculosis, systemic lupus, nor neoplasia. Moreover bacteriological cultures and HIV serology were negative. After pericardiostomy associated with corticosteroid therapy at the dose of 1 mg/kg/day, outcome was good with a resolution of the pericarditis confirmed at one-year follow-up. Since pericardial tamponade, even though rare, may be fatal in a patient with dermatomyositis, we emphasize that a two dimensional echocardiographic study should be performed in all patient presenting with dermatopolymyositis.

[Deep venous thromboses and occult cancers].

The association between venous thrombosis and cancer has been known for a long time. Thrombophlebitis often occurs during the course of a known cancer, but sometimes constitutes the presenting sign. Based on a series of 10 cases of deep venous thrombosis (DVT) revealing an underlying cancer, the authors analyse the various aspects of this association and the elements which help to guide the diagnosis towards a cancer. A simple assessment comprising clinical examination, full blood count and differential white cell count, erythrocyte sedimentation rate, protein electrophoresis, chest x-ray and abdomino-pelvic ultrasonography was performed on admission in 75 cases of presumably idiopathic DVT and revealed a cancer in 10 cases: 6 women and 4 men with a mean age of 53 years. Cancers were located in the urogenital tract in 5 cases, in the bronchi in 2 cases, in the stomach in one case, and there was one case of acute myeloblastic leukaemia (AML) and another case of liposarcoma of the left iliac fossa. The histological type most frequently encountered was adenocarcinoma in 6 cases. In 9 out of 10 cases, the cancer was discovered at the stage of metastases. However, a localized cancer was detected in one case, in which surgical treatment allowed cure of the patient. Comparison of the various characteristics of DVT between the group of DVT revealing a cancer and the group of DVT which remained idiopathic did not reveal any statistically significant difference. A simple, inexpensive assessment looking for a cancer must be systematically performed in all cases of idiopathic DVT in patients between the ages of 50 and 85 years. Other more elaborate examinations may be requested on the basis of the results of the preliminary assessment.

[Cardiac tamponade disclosing systemic lupus erythematosus].

Cardiac tamponade secondary to systemic lupus erythematosus is rare and has a very serious prognosis. The authors report a case of cardiac tamponade confirmed by echocardiography, which constituted the presenting sign of systemic lupus erythematosus in a 20-year-old patient, who required emergency pericardial aspiration. The diagnosis of systemic lupus erythematosus was established on the basis of the combination of pericardial involvement, non-erosive arthritis, leukopenia with lymphopenia, presence of LE cells and anti-native DNA antibodies and positive antinuclear antibody titre of 1/2560. The clinical course was favourable in response to 3 months of corticosteroid treatment. The possibility of SLE should be considered in any case of cardiac tamponade in a young patient in which the aetiology is not explained.

[Survey on the practice of antibiotic prophylaxis of infective endocarditis by dentists].

The authors undertook an enquiry among 287 dentists to assess their practice of prophylactic antibiotic therapy against infectious endocarditis. Of the 227 dentists who replied, most (90%) knew that a dental extraction required prophylactic antibiotic therapy. They correctly prescribed antibiotics to prosthetic valve patients (84%) and to those with post-rheumatic cardiac disease (87%). Many dentists considered that coronary bypass (66%), mitral valve prolapse without mitral regurgitation (65%) or chronic myocardial infarction (68%) also required antibiotic prophylaxis, contrary to published recommendations. Only 21% of dentists used the recommended 3 gram dose of amoxicillin; the others prescribed a lower dose or another antibiotic. Approximately half the dentists started treatment 1 to 3 days too soon and less than 5% used the recommended single dose of antibiotic. These results show that dentists do not adhere strictly to the rules of prophylaxis on infectious endocarditis defined by different working groups. The authors make several suggestions to improve the prevention of infectious endocarditis and to remedy the problems shown up by this study.
