[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.

[Impact of mitral annuloplasty combined with surgical revascularization in ischemic mitral regurgitation]. / Impact de l'annuloplastie mitrale combinée à la revascularisation chirurgicale dans l'insuffisance mitrale ischémique.

INTRODUCTION: Ischemic Mitral Regurgitation (IMR) is a serious complication of coronary artery disease and is associated with a poor prognosis. The optimal surgical treatment of IMR involves controversies in its indications and modalities. OBJECTIVES: To determine whether mitral annuloplasty associated with surgical revascularization improved short and mid terms outcomes compared with revascularization alone in patients with IMR. METHODS: Between January 2007 and January 2011, 81 patients operated on Department of Cardiovascular Surgery "B" were included in this study divided into 3 groups. Group 1: 28 patients with IMR had mitral valve surgery associated with surgical revascularization. Group 2: 26 patients with IMR had surgical revascularization without mitral valve surgery. Group 3: 27 patients without IMR had isolated revascularization. Clinical end-points were operative mortality, late mortality, postoperative functional status (NYHA), and the Effective Regurgitant Orifice (ERO) at last follow-up. The mean follow-up was 5 years for groups 1 and 2 and 4 years for group 3. RESULTS: There was no difference between the 3 groups regarding age, sex, cardiovascular risk factors, and extension of coronary artery disease. The Left Ventricle End Diastolic Diameter (LVEDD) and the Left Ventricle Ejection Fraction (LVEF) were slightly different. Late and operative mortality were higher in group 2 compared to groups 1 and 3. Postoperative functional status (NYHA) improved both in groups 1 and 2. In group 1, there was a decrease in ERO. CONCLUSION: Mitral annuloplasty combined to revascularization improves symptoms, postoperative ERO and short- and mid-term survival compared with revascularization alone.

[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.
