Apical ballooning of the left ventricle: a distinct entity?

摘要: Primary transient left ventricular apical ballooning is a distinct entity that has been diagnosed worldwide. Although neurogenic stunned myocardium often suggested as the cause, further investigation recommended Transient syndrome presenting unique morphologic feature of ventricle, characterised reversible balloon-like wall motion abnormality at apex with hypercontraction basal segment (fig 1). This was introduced “tako-tsubo-like dysfunction” in 1990 by Satoh and colleagues, several reports have followed Japan.1–5 “Tako-tsubo” fishing pot round bottom narrow neck, which used for trapping octopuses Japan.4 However, establishment its name, aetiology, criteria, management, outcome remain challenging tasks.

Recently, we reported clinical features this syndrome.5 median age our patients 74 years, 82% were female, consistent previous studies.2–4,6 Almost all had physical or emotional stress triggering factors minimum evidence coronary risk factors.
