[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.

Cardiac Catheterization↗

[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.

Angiocardiography↗

[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.

Adult↗

[Results of surgical correction of ventricular septal defects in infants].

Of a consecutive series of 91 babies aged less than 2 years, operated on for closure of a ventricular septal defect during the last four years, the 61 cases with a minimum post operative follow up period of 18 months were retained for review. Closure of the ventricular septal defect was carried out directly 41 times, and after pulmonary artery banding in the other 20 cases, using deep hypothermia with a short period of circulatory arrest and cardiopulmonary bypass.

Age Factors↗

[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.

Arrhythmias, Cardiac↗

[Closed-heart mitral valve surgery].

Good results and an absence of complications were obtained in 100 cases of closed-heart mitral commissurotomy. The present importance of digital divulsion of the beating heart is emphasised. Widening of the ostium was not hampered by the presence of calcifications or tendinous chords. Intracavitary thrombosis proved to be closely related to age, the seriousness of the symptoms, and the state of the ostium surface.

[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.
