[Circulatory assistance in high-risk coronary angioplasty].

Femoral vein to artery cardiopulmonary by-pass was used during coronary angioplasty in five high risk patients. In four patients the target vessel supplied more than half of the viable myocardium; in one of these, the ejection fraction of the left ventricle was less than 20%. In one patient the relative contraindications for surgery were the patient's age and the presence of concomitant renal failure.

[Corrected transposition of the great vessels. A clinical review of 21 cases (author's transl)].

Clinical and instrumental features of 21 cases of congenitally corrected transposition of the great vessels are reviewed. We confirm the rarity of the isolated form of the disease and its frequent association with ventricular septal defect and pulmonary stenosis. Electrocardiographically, the inversion of the first vectors is represented more frequently by the absence of the q wave on the left precordial leads than by the presence of the q wave on the right precordial leads; a very frequent electrocardiographic feature is a positive T wave on the right precordial leads.
