Abstract

We measured systemic to pulmonary bronchial blood flow [Q̇br(s-p)] during total cardiopulmonary bypass in 15 patients with mitral stenosis and elevated pulmonary venous pressure (group A, mean pulmonary wedge pressure = 22.2±5.4 mm Hg, mean±SD) and in 15 patients with coronary artery diseases and normal pulmonary venous pressure (group B). Q̇br(s-p) is the volume of blood accumulating in the left side of the heart in the absence of pulmonary and coronary flows. This blood was vented through a cannula introduced into the left atrium and measured. Q̇br(s-p) was 76.3±13.9 ml/min (2.18±0.37 percent of extracorporeal circulation pump flow) and 22.3±2.1 (0.63±0.15) in group A and B, respectively (p
