“…The prevalence of aberrant left ventricular bands, as recognized by echocardiography, ranges from 0.5% to 50%. [6][7][8][9][10] In the approximately 200 cases of aberrant bands reported, pathologic confirmation of the echocardiographic find-ings was available in only four cases.-'-Thus the reliability of two-dimensional echocardiography for recognizing left ventricular aberrant bands has not been established.…”

The accuracy of two-dimensional echocardiography in the recognition of aberrant ventricular bands and pathologic trabeculations (hypertrophic, fibrotic, or both) was assessed in 35 patients who underwent cardiac transplantation and pathologic examination. At pathologic study the prevalence of specific intracavitary structures ranged from 28% to 43%. Left ventricular thrombi were found in 12 patients (34%) and right ventricular thrombi in three (9%

“…Fifteen of 16 pediatric patients (94%) with no heart disease except the presence of false tendons reported by Perry et al [4] had a murmur with tonal qualities of Still's type. Vered et al [9] reported that none of the 9 normal subjects with false tendons had systolic precordial murmurs. In our series 6 of 19 patients (31.5%) with no cardiac disease had systolic murmurs, and 4 of 20 patients (20%) referred to our laboratory because of an 'innocent mur mur' had false tendons.…”

The echocardiographie features of 51 cases of false tendons are reported. In 35 patients (68.6%) the direction was longitudinal (4 with basal and 31 with medium and apical insertions) and in 16 (31.3%) transverse. In 1 case there was a thickened tendon; in 3 patients we noticed the simultaneous presence of two false tendons. Six of our 19 patients (31.5%) with no cardiac disease had a systolic murmur, and 4 of 20 patients (20%) referred to our echocardiographie laboratory because of an 'innocent murmur' had false tendons. The role of false tendons in the pathogenesis of arrhythmias could not be evaluated because of the presence of heart disease in 32 patients and the kind of selection in 19 with no detectable cardiac disease. In our series false tendons could easily be differentiated from vegetations, thickened septum, and subvalvular membrane, but there were difficulties in the differential diagnosis from apical thrombi in 5 cases (9.8%).

324 ResumoObjetivo -Determinar a prevalência de sopro inocente em adolescentes, avaliando a importância do exame clínico no diagnóstico do mesmo, tendo como "padrão ouro" o estudo Dopplerecocardiográfico.Método -Este estudo, realizado no período de março a dezembro de 1992, abordou alunos de primeiro e segundo graus, com idade entre 10 e 20 anos, oriundos de famílias de classes média e média-baixa. Os 536 participantes foram selecionados a partir da randomização dos 1400 alunos matriculados. Os alunos sorteados foram entrevistados e examinados por um dos pesquisadores, sendo que 27 crianças com sopro cardíaco foram submetidas a estudo Doppler-ecocardiográfico.Resultados -Dos 536 alunos examinados, 171 (32%) apresentavam algum tipo de sopro cardíaco, sendo que 160 (29,9%) foram considerados como portadores de sopro inocente, e 11 (2,1%) de "sopro não inocente". Dentre os 27 adolescentes com sopro que foram submetidos a estudo Doppler-ecocardiográfico, em 20 esse exame confirmou o diagnóstico clínico de sopro inocente, não evidenciando qualquer anormalidade ou sendo visibilizados achados considerados fisiológicos. Das sete crianças com diagnóstico clínico de "sopro não inocente", o estudo Doppler-ecocardiográfico demonstrou lesão cardíaca em dois (pequena comunicação interventricular e valvopatia reumática: dupla lesão mitral e insuficiência aórtica) e dados anátomo-funcionais normais em cinco.Conclusão -Diante dos resultados obtidos, a prevalência global de sopro inocente em adolescentes foi calculada em 29,9%. Sugere-se o exame clínico bem feito, realizado por médicos treinados em semiologia cardiovascular, é capaz de definir o diagnóstico de sopro inocente na maioria dos casos (sensibilidade de 100% e especificidade de 80%).J. pediatr. (Rio J.). 1996; 72(5):324-328: sopro inocente, ecocardiografia. AbstractPurpose -To determine the prevalence of innocent murmur among adolescents, and to evaluate the clinical features in comparison with echocardiogram (two-dimensional, M-mode, Doppler, and color-Doppler) in the assessment of heart murmurs.Methods -The study was carried out from March to December, 1992, and involved high school students coming from families of the medium and low-medium social classes. Considering the total of 1400 students registered in a public school, 536 adolescents aging from 10 to 20 years were admitted in this study. Twenty seven students with heart murmur were submitted to Echocardiography in order to find any cardiac lesions.Results -Among 536 adolescents, 171 (32%) had some kind of heart murmur. On the basis of the clinical diagnosis, 160 (29,9%) patients were classified as having innocent murmur and 11 (2,1%) as having "pathologic murmur". Out of 27 students submitted to echocardiography, 20 of them with clinical diagnosis of innocent murmur showed normal results. Among seven students with clinical diagnosis of "pathologic murmur", the echocardiography recognized cardiac lesions in two (small ventricular septal defect and rheumatic heart disease: combined mitral incompetence and stenosi...
