    ABSTRACT: To evaluate the effects of leukocyte-depleting filtration on myocardial and pulmonary protection and the inflammatory response in patients undergoing valve surgery. Fifty-two patients who underwent mitral valve or mitral and aortic valve replacement were randomized into two groups with or without a leukocyte-depleting filter during surgery. The filter was used from 10 minutes before the release of the aortic cross-clamp to the end of cardiopulmonary bypass. Total leukocyte and neutrophil counts showed a short-term reduction in patients undergoing leukocyte filtration, but there was no significant difference between the two groups during the study. Serum levels of cardiac troponin I were lower than that of the control group (p=0.030). Leukocyte depletion resulted in a significantly higher oxygenation index (p=0.002) and a lower respiratory index (p=0.003) compared with the control group. Serum levels of interleukin-8 were significantly elevated in patients undergoing leukocyte filtration compared with patients without leukocyte filtration (p=0.001). There were no statistically significant differences between the two groups with regards to the concentration of interleukin-6 and TNFα, or the duration of intensive care and hospital stay. Leukocyte depletion is associated with improved myocardial and lung protection but does not appear to attenuate the inflammatory response in valve surgery.

    ABSTRACT: Transposition of the great arteries with a ventricular septal defect and an associated aortopulmonary window is a rare anatomic combination having a high risk for pulmonary hypertension. Arterial switch with closure of the ventricular septal defect and repair of the aortopulmonary window is the procedure of choice, but a postoperative pulmonary hypertensive crisis is a common occurrence associated with significant morbidity and mortality. This report describes one case of such an anatomic lesion, which was repaired successfully with a fenestrated ventricular septal defect patch as an adjunct to decrease the risk of a postoperative pulmonary hypertensive crisis.

    ABSTRACT: The aim of this study is to evaluate the effect of fetal cardiac bypass on the production and secretion of fetal atrial natriuretic peptide (ANP) in the goat. Eighteen pregnant goats, at days 120 to 140 of gestation, were randomly divided into control (n = 8) and bypass (n = 10) groups. The control group underwent a sham procedure involving fetal sternotomy and cannulation. The bypass group underwent fetal cardiac bypass using a centrifugal pump for 30 min. Fetuses in the bypass group exhibited hypoxia, hypercapnia, and acidosis during and after cardiac bypass. The pulse index (PI) of the umbilical artery in the bypass group increased significantly after cardiac bypass compared with the control group. Tei indices of the left and right ventricles in the bypass group increased remarkably after cardiac bypass. Plasma troponin I levels in the bypass group increased significantly compared with that of the control group. Plasma ANP levels increased markedly in the bypass group after cardiac bypass, and the difference between two groups was significant. Transcriptional levels of ANP mRNA in the fetal heart elevated remarkably in the bypass group compared with the control group at 2 h after the bypass. A significant positive correlation between plasma ANP levels and Tei indices of the ventricles, plasma troponin I was observed (left ventricular Tei index, r = 0.606, P < 0.01; right ventricular Tei index, r = 0.581, P < 0.01; plasma troponin I, r = 0.275, P < 0.05). In conclusion, fetal cardiac bypass promoted the production and secretion of ANP and was associated with fetal cardiac dysfunction.
