Received June 15, 2007; We appreciate the comments and suggestions of Dr. Brutsaert regarding our report. He speculated that catecholamine-induced endocardial endothelial dysfunction could affect the apical trabeculated left ventricular wall with the highest surface-to-volume ratio preferentially in patients with Tako-Tsubo cardiomyopathy.

This is an exciting mechanism that can explain why left ventricular wall motion abnormality is localized to the apical zone. However, recent reports have demonstrated atypical forms of Tako-Tsubo cardiomyopathy exhibiting mid-ventricular akinesia with apical and basal normokinesia [1]. According to these reports, clinical characteristics seem to be similar between typical and atypical forms of Tako-Tsubo cardiomyopathy. A Japanese group demonstrated a rare case that had both typical and atypical forms of Tako-Tsubo cardiomyopathy sequentially [2]. I think that these phenomena can not be explained only by the above-mentioned mechanism. Moreover, it remains unclear why this disorder occurs predominantly in elderly females.

Further clinical and experimental studies are necessary to clarify the precise mechanism of Tako-Tsubo cardiomyopathy.
