Near-drowning syndrome: a possible trigger of tako-tsubo cardiomyopathy.

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. ⋯ 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.

AbstractWe 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.
