The authors present a patient with relapsing Pseudomonas aeruginosa endocarditis in whom cardiac catheterization with quantitative cultures falsely localized the infection to the tricuspid valve, probably because the patient was having intermittent rather than continuous bacteremia. After catheterization the patient developed mitral insufficiency and congestive heart failure. This experience suggests that quantitative cultures during cardiac catheterization may give misleading results and that the procedure may have significant complications.
作者报告了一例复发性铜绿假单胞菌性心内膜炎患者，该患者心脏导管检查时进行的定量培养错误地将感染定位至三尖瓣，可能是因为患者存在间歇性而非持续性菌血症。导管检查后，患者出现二尖瓣关闭不全和充血性心力衰竭。这一经验提示，心脏导管检查期间的定量培养可能会给出误导性结果，且该操作可能会引发严重并发症。
