To the editor: We have read the editorial on intraaortic balloon pumping by Drs. Braunwald and Maroko (Ann Intern Med 76:659-661, 1972) . . . and believe that several additional issues deserve consideration.
The principles of counterpulsation (an increase in coronary perfusion pressure and concomitant decrease in myocardial work requirements, reducing the metabolic demand-to-supply ratio) have a great many theoretical advantages for the effective treatment of ischemic heart disease, but the extent to which these effects are realized varies with each specific counterpulsation method. For instance, arterio-arterial counterpulsation, using an adjustable volume pump, has a greater ability to remove blood
