[Non-invasive cardiologic study on a soccer team]. / Studio cardiologico non invasivo in una squadra di calcio.

Fifteen professional football players have been examined with basal electrocardiography, M-mode echocardiography, bicycle ergometry, Holter dynamic electrocardiography; in six of them also, the electrocardiogram has been recorded by during a match. The aim of the research was to evaluate, by non-invasive tests, the cardiovascular status of an athletic team, with particular consideration to rhythm disturbances. The methods employed have given valuable informations. The echocardiographic investigation has frequently shown left ventricular dilation and/or hypertrophy. Dynamic electrocardiography has revealed in many subjects rhythm and conduction disturbances. No athlete has displayed severe rhythm disturbances during the bicycle ergometer test, except one, who had paroxysmal ventricular tachycardia, of complex etiopathogenetic and prognostic significance. Telemetric recording has been very useful to follow the heart action during a match, but its use was often hampered by technical difficulties.

[Echocardiographic patterns of discrete subaortic stenosis. Report of two cases (author's transl)]. / Aspetti ecocardiografici della stenosi aortica sottovalvolare. Descrizione di due casi.

The echocardiographic patterns of the discrete subaortic stenosis are reported. They consist of: narrowing of the left ventricular outflow tract, presence of extra echoes in the septal-aortic passage, abnormal movement of leaflets aortic valve, uniformal thickness of the interventricular septum and posterior ventricular wall. The cross-sectional echocardiography consent to specify the entity, the correct spatial orientation of the stenosis, and to discriminate the discrete membranous type from the fibromuscular diffuse obstruction. The Authors present two cases respectively of subvalvular aortic stenosis of membranous type and fibromuscular type, which are examined by M-mode and cross-sectional echocardiography. Cardiac catheterisation demonstrate, in the first of the cases, also the presence of dinamic obstruction. The specific diagnostic utility of the echocardiography in the investigation of these diseases is confirmed.
