JF British Heart Journal JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 641 OP 647 DO 10.1136/hrt.52.6.641 VO 52 IS 6 A1 L M Gerlis A1 H M Wright A1 N Wilson A1 F Erzengin A1 D F Dickinson YR 1984 UL http://heart.bmj.com/content/52/6/641.abstract AB Discrete delicate fibromuscular structures crossing the cavity of the left ventricle were identified on morphological examination in 329 (48%) of 686 hearts from patients of all ages with congenital heart disease, acquired heart disease, or normal hearts. These structures were also present in 151 (95%) of 159 hearts from animals of six species. Cross sectional echocardiographic findings compatible with these structures were obtained in 39 (21.7%) of 179 children reviewed retrospectively and in three of 800 (0.4%) adults studied prospectively. These structures appear to be a normal anatomical finding.
