CASE
Two cases of cardiogenic unilateral pulmonary edema are reported. Both patients presented to the emergency department with dyspnea, and chest radiography revealed unilateral infiltration, which mimics pulmonary disease. However, the patients were diagnosed with cardiogenic pulmonary edema, because echocardiography showed severe mitral regurgitation with an eccentric jet.
OUTCOME
The patients underwent mitral valve replacement and were discharged without complications.
CONCLUSION
Unilateral cardiogenic pulmonary edema is rare, and early diagnosis and treatment are difficult. Delayed treatment leads to high mortality. The major cause of unilateral pulmonary edema is acute mitral regurgitation, and the direction of the jet is suggested as a mechanism of laterality.
病例
报告了两例心源性单侧肺水肿病例。两名患者均因呼吸困难就诊于急诊科，胸部X线检查显示单侧浸润，类似肺部疾病。然而，这些患者被诊断为心源性肺水肿，因为超声心动图显示严重二尖瓣反流伴偏心反流束。
结果
患者接受了二尖瓣置换术，出院时无并发症。
结论
单侧心源性肺水肿罕见，早期诊断和治疗困难。治疗延迟会导致高死亡率。单侧肺水肿的主要原因是急性二尖瓣反流，反流束的方向被认为是导致单侧性的一种机制。
