To the Editor:

With regard to the recent study of Koyama and colleagues published in the Journal of Thoracic and Cardiovascular Surgery,1 your readers should be aware that the authors have done no more than confirm the previous observations of Savage and colleagues,2 namely, that reducing volume by constricting or resecting the apical half of the ventricular cone has no significant effect on ventricular pump function. Their findings also confirm extensive clinical studies3-6 showing that reduction of the radius of the ventricle in its upper two thirds improves pump function, provided that the ventricle had been markedly dilated prior to such an intervention. Thus, simply by using a figure-of-eight symmetrical technique of resection, Konertz and colleagues5 have achieved results that surpass the current success of cardiac transplantation.

Your readers should also note that the technique used by the Japanese group to induce cardiac failure1 produced minimal alterations in left ventricular function. Thus, having reduced . . . [Full Text of this Article]
