Abstract:
Immersion pulmonary oedema (IPE) is an under-reported and poorly understood phenomenon thought to be related to exercise-induced haemodynamic changes while submersed in water. Previous work has demonstrated reversible myocardial dysfunction during acute episodes. We present a case of IPE with concomitant, transient, left ventricular myocardial oedema characterised via MRI. This is a novel finding and may be evidence of left ventricular strain due to pressure overload or secondary to a subclinical myocarditis.
