[Tests evaluating the influence of plasma fatty acid composition on dynamics of the left heart ventricle in children with simple obesity. Part II. The composition of plasma fatty acid percentage and behavior of left heart ventricular contraction in obese children].

Plasma fatty acids contents and dynamics of the left cardiac ventricle contractions were determined in 48 children with simple obesity. Significant deterioration of the dynamics of left ventricle contractions was seen in obese children. It included prolongation of QSIIJ, QI, and PEPI and shortening of LVETI. Correlation of the total contraction time, pre-ejection period and contractility index with plasma saturated and unsaturated fatty acids levels has been demonstrated.

[Tests evaluating the influence of plasma fatty acid composition on the dynamics of contractions of the left heart ventricle in children with simple obesity. Part I. Influence of plasma fatty acid composition in children with simple obesity].

Percent composition of the plasma fatty acids in 48 children with simple obesity was determined with gas-chromatography. Thirty seven healthy, normotensive children served as the control group. An increased content of the saturated fatty acids and decreased content of the unsaturated fatty acids together with the decrease in unsaturated fatty acids:multi-unsaturated fatty acids ratio were seen in children with simple obesity.

Cardiac chambers and their walls in cardiomyopathies as evaluated with CT.

Thirty-two patients with cardiomyopathy, 25 with hypertrophic and 7 with dilated form were examined by cardiac catheterisation, left ventriculography, selective coronary angiography and ungated cardiac computed tomography. Diffuse hypertrophy, localized hypertrophy and dilated cardiomyopathy were diagnosed and assessed quantitatively based on CT linear, surface and volumetric parameters of cardiac morphology. Absolute septal thickness and left ventricular mass measured in CT image are the most discriminative attributes.

Cardiac atria and their appendages in mitral disease. ACT study.

After a bolus injection of contrast medium 15 patients with mitral disease were scanned with 10 to 15 degrees caudal inclination of the gantry. Optimal visualisation of atrial appendages and good visualisation of the atria and pulmonary veins was achieved. CT detection and localization of atrial thrombi was verified surgically; sensitivity was 75 percent and specificity was 92 percent.

Severe anaemia: its CT findings in the cardiovascular system.

Computed tomography of the upper abdomen and of the heart was performed in 21 patients with severe anemia (mean haematocrit value 0.23, mean haemoglobin content 39.6%). Gross morphology of the heart and great vessels (wall thickness, size of the chambers, lumina and walls of the vessels) were visualized in all patients without the use of contrast media. The smallest discernible difference between the normal heart muscle and blood filling its cavities was about 6-8 H and the smallest discernible difference between the aorta and the aortic blood was about 8-10 H (window width 150 H, window level 50 H). There were no CT signs of haemochromatosis of the heart, while CT measurements were highly suggestive of liver haemochromatosis in several cases. Visual evaluation of liver density in comparison to the density of blood in hepatic and portal vessels is misleading.

A CT evaluation of the intraperitoneal fluid distribution.

The intraperitoneal distribution of fluid and its detectability with a CT scanning were investigated in 13 patients during infusion of dialysate for peritoneal dialysis. An ascending pattern of spread i.e. from the lesser pelvis through the inframesocolic compartment to the supramesocolic compartment prevailed. Accumulation of fluid in the perihepatic space and in Morison's pouch as a function of fluid volume is at best approximated by a parabolic curve. Fifty to two hundred fifty ml. of fluid were detectable with a CT scanning in supine position in the majority of cases within the perihepatic space and Morison's pouch. The lowest amount of fluid detectable in the peritoneal cavity--25 ml. was found between the anterior abdominal wall and bowel loops in right decubitus.
