Abstract
Five patients with cardiogenic shock following coronary bypass surgery were treated with LVS. IABP was used combined with LVS in all patients. Three patients were weaned from LVS, and 2 patients are long-term servivors for 9 and 25 months. One hospital death occurred later (30 days) from low cardiac output and renal failure. LVS flow were maintained at 3-4 L/min. Pump flow capacity with various sizes of cannulae were evaluated using mock circulation for the development of the percutaneous LVS cannula. A sufficient flow (3-4 L/min) was obtained in the system with smaller cannulae. (ID 5-6 mm) and CFP. The percutaneous LVS system with CFP may be developed with use of these size of cannulae.
