[Giant left ventricle cardiac hydatid cyst : report of a challenging case]. / Kyste hydatique géant du ventricule gauche : rapport d'un challenge chirurgical.

Hydatidosis is a potentially fatal parasitic disease where humans are an accidental host. The cardiac location is due to the development in the heart of the larval form of Taenia Echinococcus granulosus. We present the case of a patient with a history of pulmonary hydatid cysts who presented with atypical chest pain with a huge hydatid cyst of the anterior and lateral wall of the left ventricle of 80/66 mm in diameter responsible of a thinning of the wall of the left ventricle and close relationship with the anterior descending artery and the circumflex artery. The surgery under extracorporeal circulation reconstructed the wall of the left ventricle with a double patch.

[Coronary artery bypass grafting in patients with severe left ventricular systolic dysfunction: Short- and long-term outcomes]. / Pontage coronaire chez les patients en dysfonction systolique sévère du ventricule gauche : résultats à court et à long terme.

BACKGROUND: Ischemic heart disease with severe left ventricular systolic dysfunction is a poor prognosis. Coronary artery bypass grafting is the gold treatment in this population, despite high surgical risk. AIM: The aim of our study is to evaluate the short- and long-term outcomes of coronary artery bypass grafting in patients with ischemic heart disease and severe left ventricular systolic dysfunction (LVEF≤35%). METHODS: Between May 1995 and December 2010, 171 patients with ischemic heart disease and severe left ventricular systolic dysfunction (LVEF≤35%) underwent isolated coronary artery bypass grafting. Hospital mortality, postoperative morbidity, all-cause death, cardiovascular death, and major adverse cardiovascular events (heart failure, recurrent angina, myocardial infarction, stroke) were evaluated. The mean follow-up was 9.3±5 years. RESULTS: Hospital mortality was 9.9%. Postoperative morbidity was 36.9%. Overall survival at 1-, 5- and 10-years was 97.4%, 90.5% and 43.4%, respectively. Freedom from cardiovascular death at 1-, 5- and 10-years was 98.1%, 91.8% and 55.4%, respectively. Freedom from recurrent angina at 1-, 5- and 10-years was 95.5%, 84.8% and 44.9%, respectively. Freedom from heart failure at 1-, 5- and 10-years was 89.9%, 86,8% and 53.3%, respectively. Freedom from major adverse cardiovascular events at 1-, 5- and 10-years was 88%, 82.1% and 38.2%, respectively. CONCLUSION: Based on our findings, coronary artery bypass grafting can be performed in patients with ischemic heart disease and severe left ventricular systolic dysfunction with acceptable hospital morbidity and mortality and long-term survival.

[Aortic infective endocarditis: Value of surgery. About 48 cases]. / Endocardite infectieuse aortique : intérêt de la chirurgie. À propos de 48 cas.

INTRODUCTION: Infective endocarditis (IE) is a serious disease whose prognosis depends on early management. Aortic location is characterized by its evolution toward myocardial failure and the high number of complications reasons for early surgery. AIM: To compare the short- and mid-terms results of surgery for aortic infective endocarditis (IE) in the active phase and the healed phase. PATIENTS AND METHODS: We analyzed retrospectively the data of 48 consecutive patients operated for aortic infective endocarditis between January 2000 and January 2012. The data on operative mortality, morbidity and major cardiovascular events (mortality, recurrent endocarditis, reintervention, and stroke) were analyzed. RESULTS: Twenty-three patients (48%) underwent surgery during the active phase (group I), 19 on native and 4 on prosthetic valves, and 25 patients (52%) were operated during healed endocarditis (group II) only on native valve. Mean age was 39 years (12-81) with a male predominance (83%). Rheumatic valvular disease was the main etiology of underlying valvular disease in both groups (85%). The clinical feature was dominated by signs of cardiogenic shock in group I and dyspnea exertion stage III-IV NYHA in group II. Streptococcus and Staphylococcus germs were most frequently encountered. Indication for surgery was heart failure in group I, it was related to the symptoms, the severity of valvular disease and its impact on the left ventricle in group II. An aortic valve replacement with a mechanical prosthesis was performed in the majority of cases (83%). Postoperative mortality concerned only one patient in group I. Twenty-one patients (44%) were followed for a mean of 30 months (1-72). One patient in group II died following cerebral hemorrhagic stroke related to accident with vitamin K antagonist. In both groups, there was an improvement in the functional class. No recurrence of endocarditis was noted in both groups during follow-up. CONCLUSION: The prognosis of infective endocarditis of the aortic valve is severe due to the fast progression to heart failure. Early medical and surgical approach provides good results on morbidity and mortality in the short- and mid-terms.

[Conservative mitral valve surgery in the treatment of mitral regurgitation due to infective endocarditis. Report of 21 cases]. / La chirurgie conservatrice mitrale dans le traitement de l'insuffisance mitrale infectieuse. A propos de 21 cas.

BACKGROUND: To evaluate the feasibility of mitral valve repair in patients with infective endocarditis (IE). METHODS AND RESULTS: Forty-seven patients operated for mitral endocarditis between 1995 and 2005; 21 underwent mitral valve repair. The repair was performed for acute endocarditis in seven patients at a median of 14 days after the onset of treatment and 14 patients for healed endocarditis after a median of six months. RESULTS: Mitral valve repair was feasible in 21 patients (45%). This repair involved mitral annuloplasty in 16 patients (76%), shortening or transposition of chordae in 10 patients (48%), a pericardial patch in five patients (24%), and suture of perforation in two patients (9%). Associated procedures were aortic valve replacement in seven patients and tricuspid annuloplasty in two. There were no operative deaths. The mean follow up was five years (one to 11). One patient was reoperated for severe mitral regurgitation and another had a stroke due to cerebrovascular embolism in the first postoperative years. No recurrence of infectious endocarditis occurred. CONCLUSIONS: Mitral valve repair in IE gives satisfactory results in terms of survival and symptomatic improvement with a low operative risk. With antibiotic therapy, it provides a cure of mitral lesions even when carried out in the acute phase of endocarditis. Finally, it feasible in several cases with excellent results.

[Takayasu's arteritis revealed by aortic regurgitation with ascending aortic aneurysm (About 2 cases)]. / Maladie de Takayasu révélée par une fuite aortique massive associée à un anévrisme de l'aorte ascendante (A propos de deux cas opérés).

Aortic regurgitation caused by non-specific aortitis is relatively rare, and is now considered as an important risk factor related to mortality. Aortic valve replacement surgery is the only curative treatment. Aneurismal dilatation of the ascending thoracic aorta associated with aortic regurgitation is a rare involvement in Takayasu, there are many difficult problems in surgical treatment of this lesion, because of its inflammatory nature, so steroid therapy before and after surgery is therefore vital. We report the cases of tow young Moroccans women (32-35 years-old) with an ascending aortic aneurism associated to aortic insufficiency. The subsequent evaluation of the entire aorta, demonstrated the presence of multiple steno-occlusive lesions. Aortic valve replacement was performed associated with graft replacement of the ascending aorta without coronary artery reimplantation. Histopathological examination of the ascending aorta and aortic valve, showed findings in favour Takayasu's arteritis.

[Haemangioma of the right atrium revealed by cardiogenic shock]. / Hémangiome de l'oreillette droite révélé par un choc cardiogénique.

Intracardiac haemangioma is a very rare primary benign tumour. A 20 year old female patient, with no significant previous medical history, presented to the emergency department with cardiovascular collapse and vague abdominal pains, with no peripheral signs of cardiac failure. The electrocardiogram showed sinus rhythm with diffuse reploarisation disturbances. Chest radiography revealed cardiomegaly (cardiothoracic index of 0.67) with a right paracardial opacity. Abdominal ultrasound showed a moderate peritoneal effusion and transthoracic ultrasound showed a tumour occupying the right atrial cavity but sparing the interatrial septum. The patient underwent emergency open heart surgery for tumour resection and right atrial wall repair with autologous pericardium. Histology confirmed a haemangioma. Follow-up at one month was uneventful. The clinical, diagnostic and therapeutic features of this case are underlined.
