Abstract

Study objective: The aim of this study was to measure systemic to pulmonary blood flow from bronchial circulation (Qbr[s-p]) in patients with heart failure. Design: In the absence of pulmonary and coronary flows, Qbr(s- p) is the volume of blood accumulating in the left side of the heart; Qbr(s- p) was measured during total cardiopulmonary bypass for coronary artery surgery; bronchial blood was vented through a cannula introduced into the left side of the heart and its volume was measured. Patients: Patients were subdivided according to the presence for more than 6 months (group 1, n=6) or less than 2 months (group 2, n=7), or the absence of heart failure (group 2, n=15). Measurements and results: Qbr(s-p) was 89 ± 18* mL/min, 27 ± 3, 22 ± 2, in groups 1, 2, and 3, respectively (*=p
