Cardiopericardial hydatid cysts.

Cardiac hydatic cyst is a rare parasitic disease. We reported 45 patients with cardiac hydatid cysts; 33 of the 45 had a primitive, unique cardiac cyst. Altogether, 18 patients of our series were asymptomatic, and 27 patients complained of symptoms (dyspnea, chest pain, palpitations). In 11 cases the cyst was revealed by an acute complication; 3 of the 11 had pulmonary metastatic hydatidosis. The diagnosis was based on a series of test results in which hydatid serology and imaging (echocardiography, computed tomography, magnetic resonance imaging) played a predominant role. Cystopericystectomy is the gold standard procedure but is sometimes unsuitable for particular sites. In that case, a conservative approach (partial pericystectomy) is mandatory to preserve organ function. The operative mortality rate is 5.5%. Two pericardial recurrences were reported during follow-up.

[Brucella endocarditis of native valves. Report of 3 cases].

Brucella endocarditis is a rare but a serious complication of human brucellosis. We report 3 cases, the diagnostic was suspected by the patient's history of systemic brucellosis in two cases and established by the culture of native valve material in the third. All the patients underwent surgery for non control of the infections, one patient died in immediately postoperative period by acute cardiac failure. For the other patients, there were no early or late mortality and no recurrence after a follow up of respectively 6 and 84 months. The diagnostic of brucella endocarditis needed a very high degree of clinical suspicion, it requires an early management valve replacement is in the majority of cases, followed by adequate and prolonged antibiotic treatment.

[Thoracic hydatidosis. A review of 1619 cases].

We analyzed the cases of 1619 patients who underwent surgery for hydatidosis in a chest localization to present a review of this parasitosis, endemic in Southern Mediterranean countries. A lung localization was observed in 1527 patients (94.6%). Extrapulmonary localizations were less common (5.62%) and included 42 heart cysts, 21 primary pleural cysts, 13 diaphragm cysts, 8 mediastinum cysts and 8 ribs cysts. For pulmonary cysts the sex ratio was 1: 1 (51.46% men, 48.85% women). Mean age was 24 years. A context of hydatid exposure was present in 81.8% of cases. The diagnosis was established on the basis of associated functional signs and an opacity with regular borders on the chest x-ray. Surgical treatment was simple cystecomy in 85.9% of the cases and lung resection in 14. 1%. Operative mortality was 0.785%. Pleuropulmonary recurrence was observed in 21 patients. Thoracic and pulmonary hydatidosis is easily diagnosed and treatment is well defined. It remains however a major challenge for health care with an important social and economic impact. Prevention can only be achieved by carefully designed actions against parasite transmission.

[Annulo--aortic ectasia. Prognosis and treatment].

Nine cases of aneurysm of the ascending aorta responsible for aortic insufficiency were identified between 1975 and 1989. Seven of these fell within the context of Marfan's syndrome, while the other 2 were idiopathic. Aortic leak was found to be massive from the outset in 5 cases and progressively worsened in 2 other cases. Mean follow-up was 138 months. Five patients were treated surgically, with nil mortality. Three corrective procedures were used: aortic valve replacement only or in combination with an additional procedure concerning the aorta (3 cases), or composite graft using the Bentall technique as modified by Cabrol (2 cases). There were 2 late complications among the incomplete procedures (detachment of the valve graft, recurrence of aneurysm). The 4 patients who did not undergo surgery all died: twice of aortic dissection and as a result of myocardial dysfunction in the other 2 cases. These results confirm the potentially grave course of this condition and emphasise the usefulness of routine surgery. Mastery of surgical techniques now justifies the extension of the indications of prophylactic surgery to any aneurysm having reached 6 cm. The Bentall technique modified by Cabrol remains the treatment of choice.

[Right arrhythmogenic ventricular dysplasia. A propos of 2 cases].

The authors report two new case histories of arrhythmogenic ventricular dysplasia. The disease was manifest as usual by recurrent ventricular tachycardia with apparent left lagging. Follow-up was 10 and 2 years. A review of the diagnostic and therapeutic approaches is provided based on this short personal series and on data from the literature.

[Indications and results of surgery of organic involvement of the tricuspid valve].

In this study the long-term results of 121 repairs for organic lesions of the tricuspid valve are presented, and a attempt is made at selecting the respective indications for valve replacement (VR) and valvoplasty. Tricuspid valve correction was effected by VR in 37 cases (mechanical prosthesis 26, bioprosthesis 11) and by plastic procedures in 84 cases (commissurotomy 62, alone in 12 cases and combined with annuloplasty in 51 cases; annuloplasty alone in 21 cases). The early mortality rate was 9 p. 100. Subsequently, 28 patients (25 p. 100) died and 12 were lost sight of. Deaths related to the tricuspid valve (n = 7) comprised occlusive thrombosis of mechanical prosthesis (MP) in 4 cases and 3 failures of plastic surgery including 2 commissurotomies alone (TC) and 1 commissurotomy combined with annuloplasty (CA). Among the 70 survivors who could be followed up for 36 to 230 months (mean 98 months), there were: --8 failures, 5 of which required reoperation: 3 belonged to the MP group (3 occlusive thromboses) and 5 to the TC group (failure expressed as major tricuspid valve leakage); --4 mediocre results (1 bioprosthesis, 3 plastic operations). The failures of plastic surgery were mostly due to inadequate right ventricular function; --58 successful results, principally with bioprosthesis, CA and annuloplasty alone. Altogether, 93 p. 100 of CA and 92 p. 100 of bioprostheses were free from complications, as against 37 p. 100 of TC and 65 p. 100 of MP. It is concluded that TC completed by annuloplasty ensures satisfactory results, thus allowing the indications conservative tricuspid valve surgery to be enlarged.(ABSTRACT TRUNCATED AT 250 WORDS)
