[Place of the Ross procedure (pulmonary autograft) in aortic valve surgery].

The pulmonary autograft operation consists of an aortic replacement using the autologous pulmonary valve. The pulmonary valve is substituted by a cryopreserved pulmonary homograft. This operation is in fact a delicate double valve replacement whose benefits are linked to the viability of the new aortic substitute. The pulmonary autograft has superb hemodynamic features and very low thrombogenicity. The report of a selected observation offers the occasion of defining the current indications of this operation in aortic valve surgery.

[Incidence, development and prognosis of atrio-ventricular and intraventricular conduction disorders in acute myocardial infarct].

The incidence, the evolution and the prognosis of conduction disturbances associated with myocardial infarction are described in a serie of 450 consecutive unselected patients hospitalized in a coronary care unit. Pacemaking does not seem to influence largely the natural history of myocardial infarction with conduction disturbances, which is essentially determined by myocardial power failure. Indications of insertion of a pacing catheter are presented.

[Clinical experimentation with intravenously administered disopyramide].

The intravenous injection of disopyramide (1.5 mg/kg) induces the return to sinus rhythm in about 60% of arrhythmias. When there exist perturbations of the cardiac rhythm, secondary to recent myocardial infarction, the percentage of success reaches 70%. The drug induces the disappearance of the extrasystoles in 80% of the cases, whatever the nature of the underlying cardiopathy. Although the secondary effects of the drug are slight, it is advisable to administer the substance in a slow intravenous injection (5 minutes), while controlling the arterial pressure and the E.C.G.

Pre- and postoperative myocardial and blood pool scans in a case of left ventricular aneurysm: Case report.

Myocardial perfusion scans (using 131Cs) and blood pool scans (113mIn) were performed on a patient before and after resection of a left venticular aneurysm. Although the huge aneurysm was revealed by preoperative scans, preservation of a significant mass of myocardium was evident. Postoperative scans show the reconstructed heart and the amount of residual damage. The operative findings confirmed the reliability of the scan information.
