Of 47 children over the age of 1 year who underwent repair of aortic coarctation during 1978-85, 22 had the operation performed with left heart bypass because the distal aortic pressure was below 50 mm Hg after the initial application of the arterial clamps. One further child had an elective left heart bypass. Satisfactory distal perfusion was achieved in all 23 patients. There were no deaths r...

Coronary angioplasty and coronary bypass surgery are mechanical approaches to atherosclerotic obstructions that impede coronary blood flow. In bypass surgery, arterial and venous conduits are placed beyond the proximal obstructions. By contrast, in angioplasty, the area of narrowing is expanded and now usually buttressed with a stent. Neither mechanical approach addresses the fundamental diseas...

Neurofibromatosis, otherwise known as von Recklinghausen disease, is a congenital hereditary disorder involving tissues of neuroectodermal or mesodermal origin. Involvement of the coronary arteries is, however, extremely rare. To the best of our knowledge, this represents the first report of off-pump coronary artery bypass grafting using the bilateral internal mammary arteries for coronary arte...

et al. T graft with the right internal thoracic artery to left internal thoracic artery versus the left internal thoracic artery and radial artery: flow dynamics in the internal thoracic artery main stem. A new pattern for using both thoracic arteries to revascularize the entire heart: the pi-graft. Effects of heart rate on phasic Y-graft blood flow and flow reserve in patients with complete ar...

OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...

• Keports of support of the heart in acute failure both in man and in experimental animals" have been published. The means investigated include: (1) heart-lung bypass, from the cava through an oxygenator and pump to the aorta;'" (2) veno-arterial pumping without oxygenator ; ' ' ' 3 ' 4 > (3) aortic synchronized counter pulsation to lower the pressure during left ventricular ejection and to rai...

In order to clarify the role of prostacyclin-thromboxane system (PTS) in development acute circulatory disorders early postoperative period after coronary artery bypass surgery, its condition was studied 86 patients with disease. vascular insufficiency and shock, a decrease level thromboxane blood revealed, while arterial hypertension, elevated concentrations were determined absence changes pro...

We studied the haemodynamic effects of inhaled nitric oxide 40 p.p.m. in two groups of patients after cardiac surgery (mitral valve surgery or coronary artery bypass grafting). Nitric oxide caused a significant reduction in pulmonary vascular resistance after mitral valve surgery in patients who had pre-existing pulmonary hypertension, but no change in haemodynamic state in the coronary artery ...

Abstrad------------------Hemofiltration during or after cardiopulmonary bypass has proved to be an efficient tool for hemoconcentration. Classically, the hemofilters are supplied by the arterial line and the filtration rate is mainly a function of the perfusion pressure. We have developed a convertible cardiopulmonary bypass system including a double head roller pump for blood cardioplegia appl...
