We present the long term follow-up of two groups of patients under 16 years of age in whom two different types of mitral valve prostheses were used for the treatment of mitral valve disease. Group I was formed by 74 patients with Starr-Edwards (6120) prosthesis and group II by 36 cases with Bjork-Shiley prosthesis. Group I was followed for a mean period of 11 years and group II for a mean period of 7.5 years. The clinical evolution of both groups assessed according to the New York Heart Association criteria showed improvement of the functional class (p less than 0.006). Twenty seven cases of group I and 21 of group II underwent cardiac catheterization for the evaluation of surgical results. In group I, the mean pulmonary arterial systolic pressure (PASP) decreased from 57 mmHg to 33 mmHg (p less than 0.001) and the mean pulmonary arterial wedge pressure (PAWP) from 20.8 mmHg to 12.1 mmHg (p less than 0.05). In group II, the mean PASP decreased from 59.2 mmHg to 28.5 mmHg (p less tha...

Objectif.-La ventilation manuelle au ballon peut se faire au bloc opé ratoire et/ou en ré animation chez le patient intubé ou non intubé , à l'aide de diffé rentes interfaces utilisant des valves de non-ré inhalation. La valve de Waters « nouvelle gé né ration » a progressivement remplacé la valve de Waters « historique ». L'objectif de cette é tude sur banc é tait d'é valuer la pression dé livré e par ces 2 valves dans diffé rentes conditions d'utilisation. Type d'e´tude.-É tude sur banc d'essai. Mate´riels et me´thodes.-Au total, 32 conditions ont é té testé es, en fonction de 2 dé bits d'oxygè ne (10 et 20 L/min), sans (condition statique) ou avec insufflation manuelle (condition dynamique) et 4 niveaux de pression d'ouverture de la valve. Le critè re de jugement principal é tait la mesure de la pression maximale à la sortie de la valve qui é tait connecté e à un poumon test et un banc de mesure. Re´sultats.-Les pressions mesuré es entre les 2 valves é taient diffé rentes pour la plupart des conditions é valué es. L'augmentation du dé bit d'oxygè ne de 10 à 20 L/min augmentait significativement la pression maximale pour les 2 valves. L'augmentation du niveau de pression d'ouverture de la valve entraînait une augmentation significative de la pression maximale trè s marqué e pour la valve de nouvelle gé né ration (de 4 à 61 cmH 2 O en conditions statiques et de 18 à 68 cmH 2 O en conditions dynamiques), alors que pour la valve historique la pression maximale augmentait de façon significative, mais restait toujours infé rieure à 15 cmH 2 O en conditions statiques et dynamiques. Conclusion.-L'utilisation de la valve de Waters nouvelle gé né ration doit être diffé rente de l'utilisation de la valve de Waters historique. En effet, un barotraumatisme peut être provoqué par des ré glages de pression d'ouverture de valve inadapté s. ß 2013 Socié té française d'anesthé sie et de ré animation (Sfar).

Le pronostic des coronariens peut être altéré par la survenue d'une insuffisance mitrale ischémique. Ce type de dysfonction valvulaire diffère des autres formes d'insuffisance mitrale par une atypie auscultatoire, un caractère parfois transitoire et une pathogénie souvent méconnue. Nous rapportons l'observation d'un patient présentant, suite à un infarctus du myocarde dans le territoire inférieur, une insuffisance mitrale aiguë. Nous insistons sur l'apport de l'échocardiographie mais surtout sur le bénéfice du traitement associant le remplacement valvulaire et la revascularisation myocardique sous circulation extracorporelle.

Mitral regurgitation (MR) is a serious complication of coronary heart disease. The functional form is the most frequent, often presenting with a dynamic character. The presence, and in particular the severity of MR and its dynamic character have a major impact on the medium and long term prognosis. The mechanisms responsible for MR are complex and occur in a state of disequilibrium between traction forces and closing forces, for which the significance is partly affected by the presence of asynchrony in left ventricular contraction. The therapeutic management of these patients is difficult. In cases of proven asynchrony, implantation of a biventricular pacemaker is justified. A mitral surgical procedure may be envisaged in cases of severe MR where bypass surgery is planned. In cases of moderate MR at rest, an evaluation of its dynamic character on effort can assist with the decision to undertake combined surgery.
