[Telesystolic mitral insufficiency with systolic click, mitral valve prolapse, and hypertrophic obstructive myocardiopathy].

There are several causes of the syndrome of "Late systolic murmur and mid-systolic click" due to mitral incompetence with ballooning of the valve, and, as numerous recent publications have shown, amongst them must be included abnormalities of left ventricular contraction. Seven cases have been studied by phonomechanocardiographic, cineangiographic, and haemodynamic methods, and analysis of the findings has shown that the abnormalities of contraction may be due to a cardiomyopathy, with a variable degree of left ventricular hypertrophy which is usually of patchy distribution, and leads to a certain degree of left intraventricular obstruction.

[Physical training in patients with coronary insufficiency. 2 year report of 2 center's activities].

One hundred and twenty patients went through a complete cycle of physical training. Eighty seven of them were recovering from recent myocardial infarction, eighteen had angina pectoris and fifteen were recovering from operation of aorta-to-coronary by-pass. Physical training was considered to be contra-indicated in the presence of evolutive angina pectoris, obvious signs of cardiac failure and a voluminous ventricular wall aneurysm. Severity of the anginal pains and intensity of the coronary artery lesions were not contra-indications. In all the cases, there was a decrease of the number and intensity of the pains while the extent of physical performance increased. The psychological effect was remarkable. Comparison between the maximal exercise tests before and after re-education showed an improvement of the cardio-circulatory function, as evidenced by a decreased cardiac rate, of the blood pressure and of the degree of the downward displacement of the ST segment for efforts of equal intensity.

[Massive myocardial infarct with healthy coronary arteries caused by ostial thrombosis].

Report of an exceptional case of massive anterior-wall myocardial infarction ending in death in a man aged 42, with no previous coronary history nor risk factors of atherosclerosis. Autopsy has demonstrated a thrombus obliterating the coronary artery ostium, penetrating into the first centimetre of the common trunk, while the coronary network was otherwise normal. The nature of this thrombus remains unexplained and did not seem to be of embolic origin.
