“…Because of its high capacity of presenting adaptive answer to a series of physiopathological processes and cardiovascular diseases, such as chronic renal failure, hypertension, and heart disease, the LV has become the focus of many researches for the improvement of the existing methods and obtainment of new methods of normality verification and heart disease diagnoses [2, 3]. …”

The main aim of this study was the formula application of the superficial area of a truncated prolate spheroid (TPS) in Cartesian coordinates in obtaining a cardiac parameter that is not so much discussed in literature, related to the left ventricle (LV) surface area of the human heart, by age and sex. First we obtain a formula for the area of a TPS. Then a simple mathematical model of association of the axes measures of a TPS with the axes of the LV is built. Finally real values of the average dimensions of the humans LV are used to measure surface areas approximations of this heart chamber. As a result, the average superficial area of LV for normal patients is obtained and it is observed that the percentage differences of areas between men and women and their consecutive age groups are constant. A strong linear correlation between the obtained areas and the ventricular volumes normalized by the body areas was observed. The obtained results indicate that the superficial area of the LV, besides enabling a greater knowledge of the geometrical characteristics of the human LV, may be used as one of the normality cardiac verification criteria and be useful for medical and biological applications.

Abstract: The analysis of critical end diastolic left ventricular volume (EDLVV) can add another parameter in the indication of univentricular correction in patients with post-valvotomy aortic stenosis, during the first year of life.
