Abstract

Lung consolidation is a common clinical pathology may be caused by infection process, infarction, tumor, compressed or obstructive atelectasis or thoracic spine trauma, which is sometimes life threatening. However, acute lung consolidation due to Klebsiella pneumoniae infection is very rare and has been rarely reported in the literature after tricuspid valve replacement. We report a rare case of acute lung consolidation caused by klebsiella pneumoniae after reoperation for isolated rheumatic tricuspid regurgitation. Due to the rapid disappearance of tricuspid regurgitation after valve replacement, pulmonary blood significantly increased compared with that before surgery, which led to pulmonary congestion and exudation, aggravating the probability of infection. This case underscores the risk for isolated tricuspid valve replacement in patient with long-terms severe tricuspid valve regurgitation and right heart dysfunction.
