[Palliative surgery of transposition of great vessels associated with pulmonary stenosis].

Palliative treatment for transposition of the great vessels with pulmonary stenosis (combined or not with ventricular septal defect) was studied in relation with 24 patients operated upon at Laennec's Hospital in Professor Mathey's section between January 70 and January 74. Three therapeutic attitudes are possible according to whether or not an atrial septal defect is created (Blalock-Hanlon's operation) in combination with the systemic-pulmonary artery anastomosis, and according to whether the operations are performed in one or many steps. It seems that for the badly-tolerated forms of the new-born, combination of both operations seems to be the best attitude, the curative treatment being impossible at this age.

[Mid-term fate of Beall's prosthesis in the mitral or mitro-tricuspid position. Apropos of 100 cases].

Aiming at investigation, a Beall's valve was implanted in mitral or in mitral-tricuspid positions only on 100 patients, between November 1969 and February 1972. The details of the initial valve lesions, the clinical condition of the patients, and the modalities of prosthetic replacement are described. The causes of death within the first month were analysed. None could be related with the prosthesis itself. At distance, 17 patients were lost of sight, 18 died and 51 were studied from 12-42 months after operation. It results from this investigation: -- that 84% of the patients reexamined were improved. Most of them were included in a better functional class; -- that the incidence of thrombo-embolic accidents amounted to 12% for the whole group of patients, a percentage similar to that observed with other types of prostheses; -- that in contraat, haemolysis is an obvious disadvantage of Beall's prosthesis (20 of 51 cases); -- that abnormal wears in two valves resulted in valve dysfunction compelled to re-operation. These latter two incidents have lead to abandoning this type of prosthesis.

[Origin of 1 of the 2 pulmonary arteries from the ascending aorta. Apropos of 2 surgical cases with 1 being associated with tetralogy of Fallot].

In relation with the report of two cases of branching of one of the pulmonary arteries from the aorta, it was recalled that this is a rare malformation, responsible for a severe cardiac failure with or without cyanosis in the first months of life, intensly suggestive of a left-to-right shunt. Demonstration of surprizing or unhabitual clinical or haemodynamic findings should indicate the performance of a right-sided angiography then an aortography, this being the only way to secure the diagnosis. Combination of such an anomaly with Fallot's tetralogy is exceptional. The clinical diagnosis is made more difficult by the presence of an anastomosis between the pulmonary and the systemic circulations. Only a careful analysis of right angiograms might make it possible to suspect the presence of an abnormal branching of the pulmonary artery, and to perform the aortography. The treatment is surgical in all cases, and should be undertaken early in life, as it is the only way to control the heart failure or to prevent irreversible pulmonary arteriolar lesions.
