Thirty-eight patients have been operated upon early after acute myocardial infarction with rupture of the ventricular septum. Preoperative management included bedside hemodynamic evaluation, mechanical left heart support, and pharmacologic agents. The results of the surgical repair reflected both the effectiveness and the duration of preoperative treatment.(More)
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)
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)
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)
The results of conventional operative resection of diffuse subaortic stenosis (tunnel subaortic stenosis and diffuse idiopathic hypertrophic subaortic stenosis) have been less than satisfactory. A new approach using the concept of aortoventriculoplasty was designed to allow adequate surgical resection of a diffuse subvalvular aortic stenosis. The aorta, the(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)
From January 1975 to September 1983, 615 patients underwent valve replacement using 698 bioprosthetic valves for selected indications. This group represents the third of all patients having valve replacement during the same period. Children younger than 15 years were excluded. The mean pre-operative functional class was 2.9. The early mortality rate was(More)
The Konno procedure provides adequate relief of diffuse subaortic stenosis but requires aortic valve replacement. This may be questionable in patients without aortic valve lesions. Eleven patients had diffuse subaortic stenosis and normal aortic orifice: tunnel subaortic stenosis (6 patients) or diffuse hypertrophic obstructive cardiomyopathy (5 patients).(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)
