BACKGROUND We prospectively evaluated a newly introduced minimal extracorporeal circulation system (Jostra MECC System; Jostra AG, Hirrlingen, Germany) for aortic valve surgery. METHOD In a prospective, randomized study, 100 patients underwent aortic valve replacement either with standard cardiopulmonary bypass (n = 50, group B) or with the MECC System (n(More)
PURPOSE We studied a cohort of 150 patients operated on with a new cardiopulmonary bypass (CPB) system. This is the mini-extracorporeal circulation (MECC) system. DESCRIPTION The MECC is a fully heparin coated closed-loop CPB system that includes a centrifugal pump and has a priming volume of 450 mL. Between March 2001 and September 2002, 150 consecutive(More)
Premature newborns with patent ductus arteriosus can be managed by prostaglandin inhibition, but this medical treatment carries a high risk of renal failure, and other complications such as necrotizing enterocolitis and hematologic disorders have been described. Echocardiography gives an early confirmation of shunt and surgical treatment may be proposed.(More)
The authors propose a new strategy of normothermic perfusion for replacement of the aortic arch to avoid the complications of profound hypothermic circulatory arrest. Six patients underwent complete replacement of the aortic arch under normothermia using two pumps for the body (one for the brain and the thoracoabdominal aortic branches) and one for the(More)
The authors report the case of a patient presenting with pulmonary embolism in which transthoracic echocardiography showed the presence of an intracardiac thrombus trapped in a patent foramen ovale; this was confirmed at surgery. It is rare to see this type of thrombus (which usually gives rise to paradoxical embolism) by transthoracic echocardiography.(More)
Thirty-eight patients (32 men and six women, mean age 48.1 years) were operated upon for acute dissection involving the ascending aorta. The surgical procedure included multiple peripheral arterial cannulations, resection of the initial intimal tear if found (35 cases), and obliteration of the false channel by double cuffing with Teflon of the two layers of(More)
Long-term performance of the first one hundred bioprostheses (BP) implanted was evaluated in 100 patients (pts) surviving isolated aortic valve replacement, mitral valve replacement and tricuspid replacement from October 1975 to March 1978. Follow-up was always more than 10 years. Cumulative duration of follow-up was 7,048 months. Follow-up ranged from 112(More)
The experience of prevention of nosocomial infections inside a cardiovascular surgical unit leads to insist, among the various tactics, on the quality and the mode of disinfection of the operating room and the intensive care unit, in particular, the technics of air and surface processing (by Anios) of sterilizing water (by Hyconium B and Filtranios), of(More)
