[Cardiac hydatid cysts: report of 10 cases]. / Kyste hydatique du coeur. A propos de 10 cas.

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.

Traumatic aneurysm of the bifurcation of the abdominal aorta in an infant. A case report.

Post-traumatic aneurysms are extremely rare in the infant population. We report a case of delayed abdominal aortic aneurysm that appeared in a 5-year-old female, admitted 5 months previously with contusions to the abdomen.

[False aneurysm complicating ligation of patent ductus arteriosus operated on successfully]. / Faux anévrisme après ligature d'un canal artériel opéré avec succès.

Postoperative aneurysm of ductus arteriosus is a rare complication but may be lethal without treatment. It is less frequent than spontaneous aneurysm of ductus arteriosus. We report the case of 5 years-old girl who underwent a ligation of patent ductus arteriosus complicated, 6 months later, with a false aneurysm of ductus arteriosus and endocarditis of the ductus and the aortic valve. The diagnosis of the aneurysm was suspected on the anteroposterior chest X-ray which showed a left superior mediastinal opacity and confirmed by echocardiography. Through bilateral thoracotomy, an anevrismorraphy and aortic repair was carried out without problem. The postoperative course was unremarkable.

[Spinal ischemia after biiliac aneurysm surgery related to Behçet's disease diagnosed two years later]. / Ischémie médullaire après chirurgie d'un anévrysme bi-iliaque rattaché 2 ans plus tard à une maladie de Behçet.

A 26-year-old woman underwent bypass surgery for biiliac aneurysm of unknown origin. The aorta was cross clamped below the renal arteries to insert a tube graft between the infra-renal aorta and the external iliac arteries with implantation of the internal iliac arteries on the prosthesis. Due to leakage from the posterior area of the proximal anastomosis, the proximal suture was redone. Total cross clamping lasted 65 minutes. No blood pressure drop was noted during or after the procedure. Postoperatively, the neurological examination revealed paraplegia with mild sensorial deficit and fecal and urinary incontinence. The fecal and urinary deficit resolved three months later. Nearly complete motor recovery was noted at the 18(th) postoperative month. The patient then presented oral and genital ulceration at 22 months postop leading to the diagnosis of Behçet's disease. Several risk factors have been suggested to explain spinal ischemia after abnormal aortic surgery: anatomic variablility of spinal perfusion, duration of aortic cross clamping, and intra- or postoperative episodes of hypotension. Thrombotic damage to the arterial system due to Behçet's disease could also perturb spinal blood supply and reproduce one of the mechanisms incriminated in ischemic spinal lesions occurring during aortic surgery for atheromatous aneurysm.

[Behçet's disease revealed by bilateral femoral aneurysm]. / Maladie de Behçet révélée par un anévrysme fémoral bilatéral.

Behçet's disease is a chronic vascularitis characterized by recurrent ulcers of the mouth and genitalia and iridocyclitis. Vascular complications involving venous thrombosis and arterial lesions are rare. We report a case of Behçet's disease in 30 year-old man revealed by a voluminous right femoral aneurysm and a thrombosed aneurysm of the left iliofemoral trunk. Disease exacerbation was marked by oral ulceration and ocular lesions that delayed surgical cure for 7 days. After surgical resection of the aneurysm, a femoro-femoral bypass was constructed with a polytetrafluoroethylene graft. The left iliofemoral aneurysm was left intact. After 4 years of regular follow-up, there have been no surgical complications. The timing of surgery in patients with a voluminous aneurysm is debated during phases of active 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.

[Hydatic disease of the heart presenting with pericardial effusion. A case report]. / Epanchement péricardique révélateur d'une hydatidose médiastinale. A propos d'un cas.

The authors report a rare case of multiple mediastinal hydatid cysts which ruptured in a 48 year old man who presented with a pericardial effusion. The diagnosis was confirmed by 2D echocardiography, completed by CT scan and magnetic resonance imaging. The patient was operated as a semi-emergency and the outcome was good. This case underlines the rare pericardial involvement and the severity of the complications of cardiac hydatid disease.

[Cardiac manifestations of Takayasu's arteritis: apropos of 5 cases]. / Les manifestations cardiaques de la maladie de Takayasu. A propos de cinq cas.

PURPOSE: Cardiac manifestations of Takayasu's arteritis are rarely reported in the literature. However, these symptoms are not rare and when they do occur, they determine the disease prognosis. Due to its frequency, its severe nature, and even sometimes diagnosis failure, high blood pressure is the major cause of cardiac manifestations. More specific cardiac manifestations of either coronary, valvular, or more rarely, myocardial origin may also occur. METHODS: Analysis of five cases of Takayasu's arteritis and a literature review allowed evaluation of both the frequency and characteristics of this disease. RESULTS: Four female and one male patients presenting with symptoms of Takayasu's arteritis, according to Fiessinger's score, were evaluated. Diagnosis of cardiac disease was based on clinical, echocardiographic and angiographic criteria. Four patients had related high blood pressure. Valvular manifestations were present in all the patients. They included mitral insufficiency (1 case); aortic insufficiency (2 cases), and both mitral and aortic insufficiency (2 cases). Two patients showed clinical manifestations of a myocardiac disease, and another showed coronary signs. Treatment did not involve surgery, including only antihypertensive drugs, nitrites, and diuretics associated with digitalin in case of cardiac failure. The disease outcome, including a 5-18 year follow-up, involved symptom decrease in all the patients. CONCLUSION: Despite the rarity of cardiac manifestations in patients suffering from Takayasu's arteritis, symptoms of this disease should always be investigated, as these manifestations alter the prognosis. Aortic insufficiency is the most frequently encountered cardiac manifestation.

[Hypertension and Takayasu disease. Report of 8 cases]. / HTA et maladie de Takayasu. A propos de 8 cas.

In this paper, the authors report 8 cases of Takayasu disease presenting in the form of hypertension, observed in the Cardiology of Ibn Rochd University Hospital in Casablanca between 1983 and 1995. The majority of cases presented with renovascular HT, secondary to unilateral or bilateral renal artery stenosis. More rarely, the patients presented proximal hypertension secondary to coarctation of the aorta. Medical treatment was prescribed all 8 cases, associated with surgery in 8 cases.

[Bacterial endocarditis in Morocco]. / L'endocardite bactérienne en milieu marocain.

This retrospective study was based on 157 cases of infectious endocarditis observed in the Cardiology department of Ibn Rochd Hospital in Casablanca between January 1983 and December 1994. The mean age of the patients was 27.5 years (11 to 65 years) with a male predominance (62.8%). Infectious endocarditis was secondary to rheumatic valvular heart disease in 63.% of patients and was primary in 29.9% of cases. Mitral or mitro-aortic valve involvement was clearly predominant. A portal of entry of the infection was identified in 63% of patients. It was dental in 64% of cases. Blood cultures were positive in 42% of cases with a predominance of unclassifiable Streptococci (37.8%) and coagulase-negative Staphylococci (25.7% of cases). Echocardiography was very useful, particularly in the presence of negative blood cultures. It demonstrated specific lesions of infectious endocarditis in 73.2% of cases and revealed very large, mobile vegetations in every case complicated by systemic embolism. The clinical course was complicated by heart failure (47.8%), renal failure (14.6%) or neurological lesions (11.5%). The global mortality was 28.7%, related to refractory heart failure in most cases.

[Cardiac tamponade disclosing neoplasm: apropos of 23 cases]. / Tamponnades révélatrices de néoplasme; à propos de 23 cas.

The authors report a series of cardio-pericardial metastases presenting acutely with tamponade. There were 14 men and 9 women with an average age of 39 years. The primary tumour was mainly bronchial in the men (5 cases: 20.8%) and breast (3 cases: 16.6%) or uterine (4 cases: 16.6%) in the women. The other malignancies were blood dyscrasias (5 NHL and 1 MHL) one pericardial mesothelioma, one Schwannoma, one Ewing's sarcoma and one carcinoma of the larynx. The primary tumour was not found in one case. Echocardiography showed a large, circumferential pericardial effusion in all cases and compressing the right heart chambers (RA and/or RV) in half the cases. Rounded echogenic masses implanted on the pericardial membranes (2 cases) or images of false membranes (10 cases) were also demonstrated. The clinical emergency led to pericardiocentesis with surgical drainage in 5 cases. A pleuro-pericardial window was fashioned in 4 cases. The effusion was important in all cases and bloody in 75% of cases. Cytology of the pericardial liquid was positive for malignant cells in 1 out of 2 cases. The diagnosis was made after death in 3 cases. The other biopsies, bronchial, lymph node, pleural and bone marrow also provided valuable diagnostic information. Undifferentiated carcinoma was found in 75% of bronchial carcinomas. In all three breast tumours, the histology showed moderately well differentiated adenocarcinoma. The authors underline the paucity of therapeutic measures: at this stage, pericardiocentesis is almost the only procedure apart from the cases of haemopathy. Some authors have suggested radiotherapy of the precordial region and others, intrapericardial chemotherapy.(ABSTRACT TRUNCATED AT 250 WORDS)

[Cardiovascular manifestations of hereditary dysplasias of connective tissue]. / Les manifestations cardio-vasculaires des dysplasies héréditaires du tissu conjonctif.

The purpose of this study was to demonstrate the special features of cardiovascular effects in connective tissue disorders through a group of fifteen cases observed over a period of ten years. The group consisted of eleven cases of Marfan syndrome (or Marfan-like syndrome), two cases of pseudoxanthoma elasticum and two cases of Ehlers-Danlos disease. The cardiovascular lesions were as follows: 1) dissection of the ascending aorta which was confirmed and had been treated surgically in 2 cases; 2) aneurysmal dilatation of the ascending aorta in 5 cases; 3) moderate mitral valve prolapse, which was isolated in 2 other cases; 4) distention of the mitral valve in 2 cases; 5) mitral valve prolapse combined with tricuspid valve prolapse in 1 case; the mitral incompetence was severe and made it necessary to carry out mitral valve replacement; 6) moderate aortic valve prolapse combined with tricuspid prolapse in a case of type-I Ehlers-Danlos disease; 7) Fallot's tetralogy combined with Marfan's syndrome and treated surgically in one case; 8) severe hypertension with abnormalities of the iliac and renal arteries in one case of elastic pseudoxanthoma elasticum. In three cases complications occurred leading to death, extension of the dissection of the abdominal aorta and global recalcitrant heart failure respectively. The outcome in the other 12 cases, with a mean follow-up time of 3 and one half years (range: 3 years to 7 years) was not marked by complications.
