[Foreign body in the tricuspid valve with valvular insufficiency and right-left shunt].

We present the case of a 50-year old man who progressively developed tricuspid valve insufficiency with opening of a patent foramen ovale responsible for right-to-left shunt with polycythaemia. The tricuspid valve insufficiency was due to a foreign body, probably of surgical origin as suggested by its radiological image and by the patient's previous history. It would have been introduced, far away from the tricuspid valve (compound fracture of the wrist), several years previously.

[Mid-systolic click syndrome, coronary spasm and sudden death. General review apropos of a tracing from terminal Prinzmetal's angina, recorded by the Holter method].

The authors review the literature on arrhythmias and ST changes, the principal causes of sudden death in the mid systolic click-late systolic murmur (SC-SM) syndrome, having recorded the ECG during sudden death of a patient with this syndrome by Holter monitoring. This would also appear to be the first reported case of sudden death recorded by this technique. It showed that death was caused by ventricular fibrillation which was preceded by a clinical and electrical episode of Prinzmetal angina.

[Continous electrocardiography recording in coronary insufficiency. Diagnostic value].

The accuracy of continuous 24 hour recordings (Holter's method) in the diagnosis of coronary insufficiency has been studied in 115 patients, by comparison with coronary arteriography. The technique was highly specific, but only fairly sensitive under the conditions of the study, because of the relative inactivity of the patients or the absence symptoms during the recording. It has allowed us to detect certain painfree or relatively painless forms of myocardial ischaemia which may be severe, and to have a clearer understanding of the effect of treatment.
