The absence of the normal kyphotic curvature of the thoracic spine—"straight back syndrome"—has recently been recognized as a cause of mistakenly diagnosed heart disease (1, 2). Patients who develop the syndrome often present with cardiac murmurs and radiographic evidence of seemingly increased transverse cardiac diameter, signs that mimic those of true heart disease. The condition appears to be similar to pectus excavatum, where mild hemodynamic alterations, generally not sufficient to produce cardiac decompensation, may be present (3-5). It is relevant to evaluate whether the "straight back syndrome" similarly can lead to alterations of cardiac hemodynamics. The purpose of this report
