Near-drowning syndrome and related hypoxemia triggered transient tako-tsubo cardiomyopathy in a female patient, with abnormalities reversing within 1 month.
Case Report (n=1)
Near-drowning syndrome and associated hypoxemia may act as an unusual trigger for transient tako-tsubo cardiomyopathy.
May warrant considering Takotsubo cardiomyopathy after near-drowning; Level 5 case leaves open confirmation of this trigger.
We report a case of transient tako-tsubo cardiomyopathy characterized by an unusual trigger in a woman victim of near-drowning syndrome. After 24 h, electrocardiogram changes and a typical echocardiographic pattern of apical ballooning with a mild increase of serum troponin level induced the suspicion of tako-tsubo cardiomyopathy despite the absence of chest pain. Left ventriculography confirmed the apical ballooning, and coronary angiography revealed normal coronary arteries. Electrocardiogram changes and apical contraction abnormalities were reversed within 1 month. In conclusion, we hypothesize that hypoxemia related to near-drowning syndrome could have induced transient myocardial dysfunction mediated by a sympathetic nerve activation.

Citro et al. (2008) conducted a case report in Tako-tsubo cardiomyopathy (n=1). Near-drowning syndrome was evaluated on Development of tako-tsubo cardiomyopathy. Near-drowning syndrome and related hypoxemia triggered transient tako-tsubo cardiomyopathy in a female patient, with abnormalities reversing within 1 month.
