Primary transient left ventricular apical ballooning is a distinct entity that has been diagnosed worldwide. Although neurogenic stunned myocardium has often been suggested as the cause, further investigation is recommended

Transient left ventricular apical ballooning is a syndrome presenting a unique morphologic feature of the left ventricle, characterised as a reversible balloon-like left ventricular wall motion abnormality at the apex with hypercontraction of the basal segment (fig 1). This entity was introduced as "tako-tsubo-like left ventricular dysfunction" in 1990 by Satoh and colleagues, and several reports have followed in Japan.^1–5 "Tako-tsubo" is a fishing pot with a round bottom and narrow neck, which is used for trapping octopuses in Japan.⁴ However, establishment of its name, aetiology, criteria, management, and outcome remain challenging tasks.

Reversible balloon-like asynergy at the apex with hypercontraction of the basal segment of the ventricle was observed during the acute phase and disappeared during the chronic phase. The interval between left ventriculograms from acute to chronic phase was 51 days.
