A method of performing veno-arterial modified ultrafiltration is described that utilizes conventional blood flow through the aortic and venous cannulae. A dual-pump blood cardioplegia console is adapted to aspirate blood from the cardiopulmonary bypass venous line. The blood is ultrafiltered, sent through the cardioplegia heat exchanger, and returned to the aorta via the cardioplegia needle. Ve...

BACKGROUND Patients with extensive coronary artery disease often require re-do coronary artery bypass grafting. However, autologous bypass material is sometimes sparse. Since long term patency of arterial graft material is superior to venous bypass grafting, we developed a technique to perform re-do total arterial coronary artery bypass grafting extending the right internal thoracic artery (RIT...

The use of arterial line filters has long been a standard of practice in the field of cardiopulmonary bypass. Sorin Biomedica has designed an adult hollow-fiber oxygenator that not only incorporates their Mimesys biomimicry coating technology but also has a 40-micron arterial filter as an integrated component of this unique membrane oxygenator. We did a prospective, randomized clinical trial of...

During 75 cardiopulmonary bypass experiments in dogs, a fall in arterial pressure or a tendency for the animal to take up blood from the extracorporeal circuit was noted at the onset of perfusion. To determine the mechanism of these reactions, the effect of homologous blood exchange in the dog was studied using a variety of techniques, including total and partial cardiac bypass. METHODS In the ...

We propose an arterial network model based on 1D blood hemodynamic equations to study the behavior of different vascular surgical bypass grafts in case of an arterial occlusive pathology: an obliteration or stenosis of the iliac artery. We investigate the performances of three different bypass grafts (Aorto-Femoral, Axillo-Femoral and cross-over Femoral) depending on the degree of obliteration ...

BACKGROUND Whether off-pump coronary artery bypass grafting has a late renal protective advantage over conventional coronary arterial bypass grafting with cardiopulmonary bypass use is controversial. METHODS From 1997 to 2004, 2102 cases of isolated coronary arterial bypass grafting were collected and analyzed, 1116 (53%) in the cardiopulmonary bypass group and 986 (47%) in the off-pump coron...
