Immersion pulmonary oedema and Takotsubo cardiomyopathy.

A 67-year-old female scuba diver developed a typical immersion pulmonary oedema (IPE), but investigations strongly indicated Takotsubo cardiomyopathy (TC). The cardiac abnormalities included increased cardiac enzymes, electrocardiographic anomalies and echocardiographic changes, all reverting to normal within days. This case demonstrates a similarity and association between IPE and TC, and the importance of prompt cardiac investigations both in the investigation of IPE and in making the diagnosis of TC.
