“…In spite of the constant technological innovations that allow higher and higher accuracy of the structure and in situ cardiac function assessment a lot of factors still bring important limitations to these methodologies, as it occurs in the cine nuclear magnetic resonance imaging that, despite providing an excellent anatomical definition among tissues, it cannot be used in some situations, such as in patients with uncompensated heart failure who do not tolerate the apnea needed for the exam and others who would eventually suffer from claustrophobia, as well as arrhythmia carriers and in those who make use of brain metal implants, pacemaker or cardioversor - defibrillator [ 10 , 11 ] . Therefore, for the proposed evaluation, the anatomical method was chosen, as it still presents the best way to study the left ventricular geometry [ 2 ] .…”

Introduction A feature of dilated cardiomyopathy is the deformation of ventricular cavity, which contributes to systolic dysfunction. Few studies have evaluated this deformation bearing in mind ventricular regions and segments of the ventricle, which could reveal important details of the remodeling process, supporting a better understanding of its role in functional impairment and the development of new therapeutic strategies. Objective To evaluate if, in basal, equatorial and apical regions, increased internal transverse perimeter of left ventricle in idiopathic dilated cardiomyopathy occurs proportionally between the septal and non-septal segment. Methods We performed an anatomical study with 28 adult hearts from human cadavers. One group consisted of 18 hearts with idiopathic dilated cardiomyopathy and another group with 10 normal hearts. After lamination and left ventricle digital image capture, in three different regions (base, equator and apex), the transversal internal perimeter of left ventricle was divided into two segments: septal and not septal. These segments were measured by proper software. It was established an index of proportionality between these segments, called septal and non-septal segment index. Then we determined whether this index was the same in both groups. Results Among patients with normal hearts and idiopathic dilated cardiomyopathy, the index of proportionality between the two segments (septal and non-septal) showed no significant difference in the three regions analyzed. The comparison results of the indices NSS/SS among normal and enlarged hearts were respectively: in base 1.99 versus 1.86 (P=0.46), in equator 2.22 versus 2.18 (P=0.79) and in apex 2.96 versus 3.56 (P=0.11). Conclusion In the idiopathic dilated cardiomyopathy, the transversal dilatation of left ventricular internal perimeter occurs proportionally between the segments corresponding to the septum and free wall at the basal, equatorial and apical regions of this chamber.

“…Faz-se importante, entretanto, afirmar que é correto o fato de que a disfunção ventricular precede os sintomas, e isso pode ser facilmente constatado pela elevação de biomarcadores da ICC, como as citocinas e BNP (34,35) .…”
