[Fast atrial rhythms (author's transl)].

The authors present their experience on fast atrial rhythms. Fourteen patients were studied in the first three months of life, nine of them having congestive heart failure. The electrophysiological basis of the reentrance tachycardia at A-V junction is discussed. The pharmacological treatment is reviewed, emphasizing the usefulness of verapamil. They comment on the good prognosis of the disorder, provided there is not associated congenital heart disease.

Aortic levopositions without ventricular inversion.

A multi-center series of aortic levoposition (aorta anterior and to the left of the pulmonary artery) without ventricular inversion is presented and analyzed from an anatomical viewpoint. All the cases are exceptions to the 'loop rule' and amount to 0.9% of the total number or cases reviewed. A combined study of our own cases and those reported in the literature is presented. There is a high incidence of anomalies (malrotations, juxtaposition of the atrial appendages, atrioventricular valve anomalies, ventricular septal defects, pulmonary outflow tract obstructions and abnormal conal types) which may be related to the primary cause of the aortic levoposition, suggesting that they may form part of a new syndrome of diagnostic and surgical importance. In some cases, absence of coronary sinus was noted without asplenia or left superior vena cava draining into the left atrium. The major coronary artery pattern in cases of antomically corrected malposition with two well-developed ventricles was similar to that seen with ventricular inversion. Most of these cases can be helped surgically provided accurate and detailed preoperative evaluation and operative assessment and treatment is carried out.

[Corrected transposition of the great arteries. Study of 14 cases (author's transl)].

We have studied 14 patients of corrected transposition, 12 with situs solitus and 2 with situs inversus. In all the patients, excepting one, a clinical, radiological and angiocardiographical study was performed. The associated anomalies were determining elements of the clinical situation; the patients with pulmonary obstruction and interventricular communication had cianosis, while the 4 patients with aortic obstruction or anomalies type left Ebstein show cardiac insufficiency. The simple radiological study helped us to determinate the ascendent aorta in the left side of the heart, in 9 cases. It was unusual to see the droped hilium in the right hemitorax. The more significants electrical signs were: The presence of complete A-V block, Q-waves in D2, D3 and aVF, absence of right waves in precordial leads in most of the patients and a negative T wave in a VL. Summarizing, authors believe that in this type of defects selective injection of contrast in both ventricles is the best method to establish the difference between corrected transposition and other cardiopathies with the aorta situated at the left side of the pulmonary artery.

[Left atrio-ventricular parachute valve. Clinical, angiocardiographic and anatomic study, presentation of 6 cases].

Report of 6 cases of parachute left atrio-ventricular valve, combined with complex malformations in 4. Age ranged from 24 hours to 9 years, five of them being less than 3 months old. Four girsl and two boys. All were examined post-mortem and two had angiography and chateterization. This series was compared with those described in the world literature.
