Analysis of the left heart bypass after open heart surgeries utilizing centrifugal pump (Bio-Pump; BP-50) in infancy

Abstract

Two infants, 11 and 9 months of age, underwent left heart bypass after open heart surgeries using pediatric centrifugal pump. The first case was after repair of complete atrioventricular canal defect, and the other was after Senning operation for complete transposition of the great arteries. The arterial return was made to ascending aorta in both patients, and the drainage site was left atrium in one and the anatomical right ventricle in the other. Left heart bypass was weaned after 63 and 64 hours in each patient. However, both could not survive from pulmonary hypertension crysis with pneumonia in the first, and from cerebral damage after cerebral embolism in the other. This new pediatric device appeared to be very usefull in small infants and children.
