Takotsubo cardiomyopathy findings on cardiac magnetic resonance imaging following immersion pulmonary oedema.

Immersion pulmonary oedema (IPO) can affect sea swimmers, snorkelers, and scuba divers. It can be fatal and cases are often mistaken for drowning. There has been an association between IPO and the development of takotsubo cardiomyopathy. We present a case study of a diver rescued from the water with IPO, who was subsequently found to have takotsubo cardiomyopathy on cardiac magnetic resonance imaging (CMR). This case demonstrates CMR findings as well as follow- up investigation results. The diver's and instructor's perspective during the initial dive incident are also described.
