Key result
Immersion pulmonary oedema case shows transient LV myocardial oedema on MRI, suggesting strain or subclinical myocarditis.
Why the study?
Immersion pulmonary oedema is an under-reported and poorly understood phenomenon thought to be related to exercise-induced haemodynamic changes during water submersion.
Case Report (n=1)
This case report presents a novel finding of transient left ventricular myocardial oedema in immersion pulmonary oedema, suggesting potential mechanisms of pressure overload or subclinical myocarditis.
May warrant cardiac MRI in immersion pulmonary oedema; leaves open whether oedema reflects strain or subclinical myocarditis.
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.

Oldman et al. (2023) conducted a case report in Immersion pulmonary oedema (n=1). Immersion pulmonary oedema was evaluated on Left ventricular myocardial oedema. A case of immersion pulmonary oedema demonstrated concomitant, transient left ventricular myocardial oedema on MRI, suggesting possible left ventricular strain or subclinical myocarditis.
