[Systolic ejection murmur in the differential diagnosis of isolated aortic insufficiency and its association with stenosis].

As assessment of the value of systolic ejection murmur in the differentiation of valvular insufficiency with and without stenosis was carried out by means of ECG, polycardiography and M-mode echocardiography in 60 patients with aortic valve disease divided into 35 subjects with and 25 without stenosis. Attention was directed to the configuration of the murmur, with particular reference to the proto-, meso- or telesystolic location of its acme and the Q-acme distance. It was found that the acme was meso or telesystolic in all cases where stenosis was present, whereas it was proto- or very initially mesosystolic in its absence.

[Mitral valve prolapse. Age and sex incidence, echocardiographic diagnosis and clinical and electrocardiographic correlations].

The paper reports an electrocardiographic and M and B-mode echocardiographical study in 3682 non-selected patients among which a total of 241 were identified with mitral valve prolapse. In males the highest frequency was found during the second decade of life with a tendency to decrease with increasing age. In females, who were found to be the most severely affected (2:1 in relation to males), two peaks of incidence were observed during the third and fifth decade, with a greater frequency in the latter and a marked absence of cases in the fourth decade. Many echocardiographically diagnosed mitral prolapses were both clinically and electrocardiographically silent; moreover it was observed that the risks of this complication increased in parallel to the thinness and redundance of the mitralic flap affected by prolapse and the dilation of the valvular ring.

Experimental study on the correlation between cardiac function and ovarian hormones.

Results of the study of cardiac function carried out on young women during various phases of the menstrual cycle were correlated to those obtained after acute administration of progesterone. In all cases systolic time intervals reveals a reduction of mechanical systole and of preejection. Direct action progesterone on cardiac function by an unknown mechanism was confirmed.
