[Catheter embolism. Method of bloodless extraction].

A detailed review and analysis of world literature on the techniques employed for the retrieval of polythene catheter fragments, metal spindles or Pudenz catheters from the heart or large vessels is presented. Non-surgical retrieval techniques are discussed on the basis of 174 cases reported in the literature. 2 personal cases of the retrieval of foreign bodies from the heart using a Deyhle-Seubert catheter are presented.

[Left endoatrial myxoma. Notes on a case].

A case of left endoatrial mixoma, ecocardiographically discovered and successfully operated, is reported. The usefulness of ecocardiography, especially to discover intracardiac masses, is considered.

[Anti-arrhythmic effects of cardioplegic myocardial protection].

Cardioplegia gave excellent results in a preliminary series of 33 cases in which it was used during surgery. The fact that a sinus rhythm was re-established at the end of extracorporeal circulation in patients in atrial fibrillation suggests that it exerts an antiarrhythmic action at the atrial a level.

[Indications for permanent cardiac pacemaking].

Technical improvements have considerably extended the indications for the implantation of pacemakers. Nearly all forms of bradyarrhythmia and some forms of tachycardia, including sinus node disease, have gradually been added alongside stable A-V blocks, while preventive implantation is now commonly indicated in asymptomatic forms and bradycardia due to drugs. The recent appearance of rapid-pulse and scanning pacemakers has further extended their indication to cover other forms of ectopic and reciprocating tachycardia.

[The battery-state control. A new possibility for the control of pacemakers. Preliminary report (author's transl)].

After a brief examination of the technical problems of current pacemakers, with special reference to the battery state control, the authors present a new technique for such control. A power stabilizer able to generate a standard pulse of 4.3 in every condition of battery charge has been fitted on the power supply of a fixed rate pacemaker of normal production. By activating (through an external magnet) such apparatus, it is possible with an easy oscilloscopic measurement to obtain the real value of the battery voltage. Thus the comparison with previously taken measurements and the errors connected with the repetition of such measurements can be avoided. The stimulation rate and the pulse duration corresponding to the discharged state of the batteries can also be known in advance. The data obtained from the first two controls are reported.

[Theory concerning a possible mechanism of displacement of intracavitary electrode catheters].

Reference is made to three cases in proposing an explanation for the shifting of endocavitary catheters, namely traction of the lead attached to the lower side of the stimulator owing to movement of the apparatus, resulting in displacement of the tip. It is pointed out that the intravasal length of the displaced catheter is markedly decreased in 3 out of 4 cases. Attention is therefore drawn to the importance of the relation between catheter and stimulator in causing a high percentage of the case of displacement observed.
