Investigation of articles about the contractility in Fontan published in PubMed up to now revealed that the measurement of contractility values did not include the rudimentary ventricle. Connections between right atrium and right ventricle as well as right atrium and pulmonary artery were studied in the same group as well. In our opinion, for the single ventricular physiology, the RA-RV and RA-PA connected patients’ preload and afterload values cannot be calculated in the same group since volume of rudimentary ventricles must be considered from this point of view as well.展开更多
