| pubmed-article:19233763 | pubmed:abstractText | Left-ventricular end-diastolic volume index (LVEDVI) and Nakata index, which in most cases are evaluated by echocardiography and cardiac catheterization, are 2 important predictors for the prognosis of surgical correction of tetralogy of Fallot (TOF). Nonetheless, performing these procedures on TOF patients is not always feasible. We therefore investigated whether the difference in transcutaneous pulse oxygen saturation between the standing position and squatting position (DeltaSPO2) reflected the LVEDVI and Nakata index, allowing DeltaSPO2 to be used as a supplement to echocardiography and cardiac catheter evaluation. | lld:pubmed |
