[Place of conservative surgery in acquired valve diseases].

There is still a place for conservative surgery in valvular disease of the heart to the extent that artificial prostheses have not yet been perfected sufficiently for them to be regarded as the method of choice. While these conservative operations are rarely applicable to the aortic valve, techniques such as Carpentier's ring occupy an important place in the treatment armamentarium for disorders of the mitral valve, and even more so of the tricuspid valve.

[Endocardial resection: surgical treatment of constrictive fibrous endocarditis].

A new operation, the resection of the endocardium, is proposed in the case of fibrous constrictive endocarditis. I performed this operation in 1971, for the first time, with good results. I operated on two other patients with success in 1973 and 1975. The results I have obtained indicate that this new technique is possibly the answer to a disease which otherwise ultimately results in death.

[Supravalvular ring type aortic stenosis with hypoplasia of the ascending aorta and stenosis of the origin of the innominate artery. Surgical correction].

The authors report the case of a 19 year old woman with supravalvar aortic stenosis and hypoplasia of the ascending aorta with stenosis at the origin of the innominate artery. This was a sporadic form, without mental deficiency nor facial dysmorphia. No similar case was found in the family. The patient had three attacks of bacterial endocarditis over a period of 3 years and became cured without any cardiac sequelae. In view of the onset of left ventricular failure and sequelae. In view of the onset of left ventricular failure and syncope, operation was decided. A lozange-shaped patch was placed on the aorta from the narrowed supravalvar part to the origin of the innominate artery and prolonged on the latter vessel after relief of the stenosis. This gave an excellent result.

[Hyperparathyroidism. Reoperations].

Sixteen patients were re-operated on for treatment of their hyper-parathyroidism. After analysis of the cause of failure or relapse, the authors discuss the examinations which led to a definite diagnosis and, in some cases, pre-operative localisation of the lesion. All the patients were treated by the cervical route only. Operation may be very difficult Technical advice is given here. Tetany and recurrent laryngeal nerve paralysis are common complications. They are often due to an inefficacious or incomplete first operation.

[Gastric lesions caused by potassium permanganate tablets. Measures to be taken after ingestion].

Potassium permanganate tablets are caustic and it has been suggested that they should be removed straightaway by gastrostomy, immediately after swallowing. Some operators have been impressed by the macroscopic appearance of the stomach and have carried out gastrectomy. However, the lesions were only fairly superficial on pathological examination. In the light of a new case and 21 similar cases, treated at the Fernand Widal hospital, the authors discuss other cases in the literature. They conclude: the extreme rareness of digestive perforation; the absence of toxicity of breakdown products of potassium permanganate. They propose treatment of neutralisation of the permanganate with sodium hyposulphite, gastric lavage and supervision on a surgical unit. In case of perforation, they believe that the operation should be conservative.

[A surgical series of 128 cases of mitral insufficiency caused by chordae tendineae rupture].

In relation with 128 cases of surgical operation for mitral incompetence through ruptured chordae tendinae, the aetiological, anatomical and clinical characteristics of these cases were described. Bacterial endocarditis and spontaneous rupture were present in 77 percent of cases. In 94.4 percent of the cases, the patient coming to operation was in a high functional class (class III and IV of the NYHA). Operation included valve replacement in 100 cases (by a Starr-Edwards prosthesis), while the mitral valve was preserved in 28 patients. The conservative operation presently performed combined the resection-suture of the deinserted area and a reconstitutive valvuloplasty over a Carpentier's ring. Results of this surgery are good in more than 90 percent of the cases.
