[Left ventricular kinetics in bundle-branch block. Analysis by different methods in patients without coronary artery diseases (author's transl)].

Radiological ventriculographic findings of twenty-three patients with left bundle branch block (LBBB) without valvular heart disease and without evident coronarographic lesions are studied by means of six differents methods for quantitative evaluation of wall motion analysis. The patients are subdivided into two subgroups on the basis of hemodynamic criteria, but the results of wall motion studies are similar in both, if the values obtained are normalized for election fraction (EF). End-diastolic images of left ventricle are similar in both subgroups too, but very different from those of normals because apical region is characterized by rounded contour of images. The modes of contractility in LBBB patients evidence, after normalization by the same EF, hypercinetic motility of anterior wall. The patterns of contractility, shaped by progressive simulated EF, show that low EF are obtained through contraction of anterior wall. Greater EF are obtained by further uniform contraction of all the explored regions. The apical zone in LBBB patients is affected by persistent hypokinesis.

[Distribution and anomalies of coronary arteries in tetralogy of Fallot (author's transl)].

Anomalies in the course and distribution of coronary arteries may complicate the surgical correction of tetralogy of Fallot (TF). With the aim of preventing possible serious, and even lethal, cardiac events caused by the injury of aberrant vessels, 119 patients with TF were subjected to selective coronary angiography. Apart from demonstrating anastomoses between the coronary and bronchial arteries in 31 cases, small fistulas between the coronary arteries and pulmonary artery (in 14 cases) and hypoplasia of the entire coronary tree in 1 case, this investigation revealed anomalies in the origin of coronary branches in 11 cases. In some cases the first septal branch was absent and the diagonal branches were poorly developed. An injury to the coronary system, following the closure of the interventricular septal defect, may possibly explain the onset of a "left anterior hemiblock" after total correction of TF. Selective coronary angiography in small children presents no riskes provided it is correctly performed. In our cases no complications arose.

[Myocardial infarction in young people. A coronary angiographic study in 21 patients under the age of 30 (author's transl)].

The Authors have taken into account 21 patients who complained of myocardial infarction before they were 30 years old. We performed coronary angiography, left ventriculography and left cardiac catheterization in all the patients. In 20 cases we found atherosclerotic alterations (50 or greater obstruction) at least in one of the three main braches of coronary tree. The coronary angiography in one patient showed a picture of dissection of right coronary. The alterations are localized more frequently on the anterior descending branch than on the right coronary. On the contrary we found very seldom atherosclerotic lesions on the circumflex artery. Monovascular alterations were more frequent than plurivascular alterations (more than 40% of the total). Left ventricular function was out of order in almost all cases. In summary the important differences between young patients with myocardial infarction and older patients are the following: 1) from the clinical point of view the sudden onset of myocardial infarction without previous symptoms of angina pectoris; 2) from the angiography point of view high incidence of monovascular alterations and low incidence of collateral circulations.

[Positive ionotropic action of glucose-1-phosphate. Clinical research during heart catheterization].

The effect of glucose-1-phosphate, administered in a single dose (5 g by slow intravenous route), on myocardial contractility was evaluated in a group of patients undergoing diagnostic cardiac catheterization. The study of the hemodynamic values observed demonstrated that glucose-1-phosphate has positive inotropic action and is able to strengthen the effect of the cardioactive glucosides.
