We thank Dr DeGroff for his comments on our study of ventricular mechanics during repair of tetralogy of Fallot.1 We acknowledge that the use of 2-dimensional echo sections to represent the 3-dimensional left ventricle (LV) is limiting. The degree of error introduced by this compromise is unknown in the absence of more comprehensive imaging. However, we believe that our conclusions are essentially correct.As noted, Matsumori et al2 defined limitations of a biplane Simpson rule for LV volume determination in the presence of right ventricular (RV) pressure and volume overload. A modified Simpson rule, including area planimetry of …
