Measurement of cardiac output in ventricular rupture following acute myocardial infarction--pulmonary artery catheter vs transpulmonary thermodilution--a case report.
We compared the cardiac output measured by the transpulmonary aortic single indicator thermodilution method with that by the pulmonary artery catheterization in a patient with ventricular septal rupture after acute myocardial infarction. Though the former cardiac output was lower than the latter, in the presence of the ventricular septal rupture, the cardiac outputs were equal after the rupture was closed. This indicates that, while the cardiac output measured by the pulmonary artery catheter is influenced by the ventricular left-to-right shunt, transpulmonary aortic thermodilution method measures the true cardiac output of the left heart, which is responsible for organ perfusion.
