2014, Journal of the American Society of EchocardiographyCitation Excerpt :We did not calculate LV twist angle indexed for LV length (i.e., LV torsion), as observed in previous studies.17 However, endurance training induces a homogeneous cavity dilation, including increased LV length,17,41,42 and consequently indexing twist angle for LV length would have strengthened the difference observed in LV twist angle between athletes and sedentary subjects. Another limitation was the cross-sectional design of the study.

2007, Cardiology ClinicsCitation Excerpt :Resolution of this dilemma has relevant clinical and legal consequences, because the correct identification of the physiologic nature of LV dilatation may avoid an unnecessary withdrawal of the athlete from competitions and the unjustified loss of the varied benefits (including economic) derived from the sport [20]. Certain criteria have been suggested to help in this differential diagnosis: in patients who have DCM, the LV cavity is disproportionately enlarged and modifies to a more spherical shape [19]; in trained athletes, LV cavity enlargement is associated with consistent enlargement of the right ventricle; indeed, the physiologically dilated LV cavity maintains the ellipsoid shape, with the mitral valve normally positioned and without mitral regurgitation [21,22]. The most definitive evidence for DCM is, however, the presence of global systolic dysfunction (ie, ejection fraction <50%) or evidence of segmental wall motion abnormalities.

2007, Journal of Science and Medicine in SportCitation Excerpt :This morphologic finding raises a differential diagnosis between an extreme cardiac adaptation to intensive exercise training and a pathologic cardiac condition with the potential for adverse clinical consequences. In dilated cardiomyopathy (DCM) patients, the LV cavity is disproportionately enlarged and is modified to a more spherical shape;22 In trained athletes LV cavity enlargement is associated with slight enlargement of the right ventricle; indeed, the physiologically dilated LV cavity maintains the ellipsoid shape, with the mitral valve normally positioned and without mitral regurgitation.23,24 The most definitive evidence of DCM is the presence of global systolic dysfunction (i.e., ejection fraction less than 50%), and/or evidence of segmental wall motion abnormalities.
