Right and left heart volumes, ejection fractions and ventricular outputs were determined from biplane cineangiocardiograms in infants with symptomatic coarctation of the aorta and correlated with clinical and hemodynamic alterations. Patients were divided into two age groups: group 1, aged 3.5 to 14 days and group 2, 5 weeks to 7 1/2 months. Infants in group 1 had severe depressions of left ven...

We believe that right ventricular enlargement is "over-diagnosed" radiologically, and this becomes apparent when radiologic interpretation is attempted without the help of other data. We tested this impression in a study of 25 cases of tetralogy of Fallot and 40 cases of other types of congenital pulmonary stenosis. In these cases there was usually no right ventricular dilatation. The roentgen ...

We report on an 80-year-old woman who had shunt-responsive idiopathic normal pressure hydrocephalus (iNPH). Her brain MRI showed an initial change in the subarachnoid space (a disproportional narrowing of the subarachnoid space at the cerebral high convexities) at the age of 70 years, followed by enlargement of the ventricles (Evans index: 0.31) at the age of 78. The observation suggests that c...

Echocardiographic examination of 21 patients with Friedreich's ataxia (age 7 to 28 years) showed cardiac abnormalities in 90% of the cases. They were characterized by varying degrees of septal hypertrophy in 81%, left ventricular free wall hypertrophy in 61%, and a slight reduction of left ventricular internal dimension in 57% of the cases. Asymmetric septal hypertrophy (ASH) with a septal/left...

SUlMMARY To assess the effects of a natural volume overload state (pregnancy) on left ventricular function we recorded echocardiograms each trimester (TM) and four to 12 weeks postpartum. Heart rate increased from 77 ± 2 (SEM) to 88 ± 2 heats/min (TM I vs TM 3, P < 0.01) and declined to 69 ± 2.0 beats/min postpartum (P < 0.05 vs TM 3). Despite these changes, end-diastolic dimension increased fr...

Athletes often exhibit ECG findings which are considered to be abnormal. Therefore, we used noninvasive graphic methods to study 42 active professional male basketball players, ranging in age from 21 to 31 years, without clinically evident heart disease. Of the 42, 11 (25%) met the Romhilt-Estes ECG voltage criteria for left ventricular hypertrophy, and 12 (29%) satisfied VCG criteria for left ...
