[Study of the descending phase of the aortic pressure curve. Possible applications to the monitoring of peripheral resistance and arterial compliance (author's transl)].

In 21 patients aortic pressure was recorded just above the diaphragm. The curve after the dicrotic notch is an exponential function of the time, and it is possible to characterize it by a unique time-constant. This constnat is shown to depend on aortic compliance and peripheral resistance: as aortic compliance does not vary abruptly in physiological conditions, this allows monitoring of peripheral resistance by monitoring time constant. Mathematical bases of time constant and of the peripheral resistance are briefly discussed.

[The congenital coronary artery fistula. Observations on seven cases (author's transl)].

The authors report seven cases of congenital coronary artery fistula observed in the Cardiology Department of Padua Medical School. The cardiopathy, the anatomo-histological characteristics, evolution and embriology are described. The anamnesic, clinical, electrocardiographic, X-Ray, phonocardiogram, haemodynamic, and contrastographic findings for each case are given. They are discussed and interpreted in the light of the pathophysiology of the disease.

[Pre- and postoperative ECG-VCG study of the correction of atrioventricular septal defects].

In order to determine the possible implication of the right bundle branch block (RBBB) in the superior axis deviation of patients (pt) affected with AV septal (Canal) defect, we studied the preoperative and postsurgical ECG of 50 patients who underwent radical correction of the malformation complex. 36 pt had the complete form and 14 a partial form. In 14 of them it was also possible to perform a VCG before and after surgery. The amplitude of S1, R' in a VR and V1 modified significantly (p less than 0.0001), the AQRS showed a clockwise displacement of 19 degrees (p less than 0.002). The terminal forces in the VCG frontal plane changed significantly 62 degrees (p less than 0.0001). Nevertheless the D.I. in a VL and V6 made no difference. Postoperative ECG patterns of pt with partial or complete forms did not differ substantially. Results allowed us to conclude that the major determinant of the AV septal defect ECG pattern is the posterior (inlet) deficiency of the interventricular septum. Surgical correction of the right ventricle overload leads to a clockwise AQRS displacement in the frontal plane. The conduction asynchronism through the left branch showed no modifications.
