A 9-year-old boy with congenital atresia of the left main coronary artery underwent myocardial revascularization. Coarctation of the aorta and ventricular septal defect were diagnosed at the age of 1 year. At age 7 years, the child presented with syncope while exercising.

Background: The prediction of pulmonary hemodynamic data from non-invasive assessment could exempt some patients with congenital cardiac septal defects from preoperative invasive assessment (catheterization).

Objective: To determine, in simultaneous assessment, whether data obtained from Doppler echocardiography could predict aspects of pulmonary hemodynamics in such patients.

Methods: Echocardiographic parameters related to systolic and systemic pulmonary flow and pulmonary venous flow were related to hemodynamic data in 30 consecutive patients with cardiac septal defects (aged 4 months to 58 years, median 2.

Background: In patients with congenital heart disease undergoing cardiac catheterization for hemodynamic purposes, parameter estimation by the indirect Fick method using a single predicted value of oxygen consumption has been a matter of criticism.

Objective: We developed a computer-based routine for rapid estimation of replicate hemodynamic parameters using multiple predicted values of oxygen consumption.

Materials And Methods: Using Microsoft® Excel facilities, we constructed a matrix containing 5 models (equations) for prediction of oxygen consumption, and all additional formulas needed to obtain replicate estimates of hemodynamic parameters.
