[Repeated heart valve replacements: prognosis and results].

In order to determine the prognosis of reoperation for valvular replacement, we reviewed the results of a consecutive series of 124 patients operated in the department between 1974 and 1992 (163 multi redo operations). There were 69 women and 55 men, with a mean age 48 years; 77% of the patients were in functional class III or IV. Operations were performed as an emergency in 30% of cases. Endocarditis was found in 24% of cases and was an important risk factor in this content. The main indications for reoperation were periprosthetic leakage in 28.8% of cases and failure of bioprostheses in 23.7%. The valvular replacement was simple in 61%, double in 32% and triple in 7% of cases. An associated procedure was necessary in 27% of cases. Mechanical devices were implanted in 62.3% of cases. Peroperative mortality was 3% and hospital mortality, mainly from cardiac causes, was 21.7% for the second, 20% for the third and 55.6% for the fourth reoperations. Operative mortality was dependent on the number or reoperations, functional class, emergency surgery, duration of bypass and cross-clamping time. Four per cent of patients were lost to follow-up and 30 patients died secondarily. The actuarial survival rate was 52% at 5 years and 33% at 10 years, actuarial survival rate without valvular complication was 41% at 5 years and 19% at 10 years but the functional results remained good with over 90% of patients in functional class I or II at the end of follow-up.

Right-sided aortic arch: surgical treatment of an aneurysm arising from a Kommerell's diverticulum and extending to the descending thoracic aorta with an aberrant left subclavian artery.

The case of a 44-year-old black man who presented with severe dysphagia, cough and chest pain caused by a 12-cm aneurysm developing from a Kommerell's diverticulum at the origin of an aberrant retro-oesophageal left subclavian artery is reported. The aortic arch and descending thoracic aorta were right sided. Diagnosis was established before operation by computed tomography, magnetic resonance imaging and arteriography. The aneurysm extended a considerable distance down the descending aorta and therefore the risk of postoperative paraplegia was considered to be high. Accordingly selective arteriography was performed to locate the Adamkievicz's artery which arose only 2 cm below the end of the aneurysm. Resection grafting of the aneurysm including the upper third of the descending aorta via right thoractomy was performed. The patient made an uneventful recovery and was discharged 20 days later. This case appears to be the first successful operation for this pathology.

Behçet's syndrome and factor XII deficiency.

Several mechanisms have been proposed to explain thrombotic tendency in Behçet's syndrome. We report the case of a 43-year old woman presenting retinal-vein thrombosis, factor XII deficiency and Behçet's syndrome. This kind of association has thus far never been reported. Factor XII deficiency is known to possibly induce various types of thrombosis and might explain the prevalence of ocular symptoms in our patient.

[Clinical history and anatomic findings following the longest survival after cardiac transplantation].

The authors report the case history of the first patient in the world to have survived 18 and a half years with a heart transplant. This survival was marked by several episodes of rejection during the early years and various other incidents. The pathology encountered was primarily iatrogenic: diffuse osteoporosis sometimes limited the patient's activity. Two skin cancers and a lung cancer were diagnosed and treated. The patient died from progressive respiratory failure with pulmonary hypertension and signs of right ventricular failure. Pathological examination revealed a subnormal myocardium with a certain amount of overloading of the coronary arteries, confirmed the lung cancer and pulmonary hypertension and, most importantly, revealed the presence of nodular regenerative hepatic cirrhosis responsible for ascites during the last few months of life and a renal adenocarcinoma. These last two lesions are observed in immunosuppressed patients. The authors pay tribute to this patient who led an active and devoted life in the service of others.

[18 and one-half years' survival after cardiac graft. Clinical course and anatomical findings].

Operated upon in November, 1968, the last survivor of heart transplant recipients in those times has died on May 11, 1987, having survived 18 years and 6 months. The active life of this patient, however, was marred by episodes of graft rejection during the first post-operative years and by various incidents. It was mainly the complications of the immunosuppressive treatment that hampered his activities (osteoporosis) and provoked his death. Post-mortem examination confirmed that the heart was in good condition, found an active bronchial epithelioma and revealed iatrogenic lesions, namely adenomas, adenocarcinoma of the kidney and "regenerative" nodular hyperplasia of the liver with portal hypertension. Such lesions are observed in patients under long-term treatment with immunosuppressants. A "sleep apnoea" syndrome might have accounted for the formation of pulmonary hypertension lesions. The authors wish to pay their respects to this man who devoted himself to the service of other men.

Triple valve procedures: an analysis of early and late results.

This study summarizes the results in 107 patients with triple valve procedures (TVP) performed between 1972 and 1983. Forty-five patients underwent double valve replacement with tricuspid annuloplasty, and 62 simultaneous triple valve replacement. The hospital mortality was 19.6% (21 patients) and was influenced by: the preoperative functional class: 4.7% (1 of 22 patients) in class II, 13.7% (7 of 51) in class III and 37.2% (13 of 35) in class IV (p less than 0.05). the urgency of operation: 13.2% in elective operations (11 of 83 patients) and 41.6% for emergencies (10 of 24) (p less than 0.02) the type of tricuspid procedure: 15.5% for annuloplasty (7 of 45 patients), 21.1% for bioprosthetic replacement (11 of 52) and 30% for mechanical valve replacement (3 of 10) (p less than 0.05). Other factors such as patient age, right ventricular systolic pressure (RVSP) and type of myocardial protection had no significant influence. The late mortality was 9% per patient-year (18 patients, 9 of whom died in the first year), the majority related to cardiac causes. The 5-year survival rate was 53%. It appears that the survival rate is higher if the patient is in preoperative functional class II (55%), the right ventricular pressure is below 60 mmHg (67%), and if the operation is performed electively (57%). The findings suggest that surgery should continue to be offered to such patients.

[Percutaneous transluminal valvuloplasty in pulmonary stenosis. Apropos of 24 cases].

Twenty-four patients with moderate or severe valvular pulmonary stenosis were treated by percutaneous transluminal valvuloplasty (PTV). The age of the patients ranged from 24 hours to 27 years. Eighteen patients (group I) had a right ventricle-pulmonary artery (RV-PA) pressure gradient greater than 50 mmHg (measured simultaneously or during catheter withdrawal). Six patients (group II) had RV-PA pre-sure gradients of less than 50 mmHg. Twenty-seven PTV procedures were performed. Six of the 24 patients were under 2 months of age, including 4 who were less than 1 week old. The youngest patient (under 24 hours old) had valvular pulmonary stenosis, very nearly atresia. PTV was carried out using Rashkind's technique on 2 occasions and with a dilatation catheter with a balloon of 6 to 20 mm of diameter on the other 25 occasions. In 6 cases, 2 dilatation catheters were introduced and inflated simultaneously in the pulmonary valve. The overall results were satisfactory: RV pressure fell from 87.6 to 54.4 mmHg, the RV-PA gradient from 72.3 to 31.9 mmHg and the ratio of RV/systemic pressure from 104.4 to 51.1. The improvement was more marked in group I than in group II. The causes of failure are discussed: valvular dysplasia, severe infundibular hypertrophy, inadequate diameter of the balloon. Tolerance of PTV was very good. The value of this procedure is emphasised. It may save surgical valvotomy in high risk groups of patients, such as the newborn and infants. The haemodynamic results of PTV are maintained at long-term, but the number of cases is still too small.

[Ventricular arrhythmia following repair of Fallot's tetralogy. Apropos of 59 cases].

Fifty-nine patients operated for Fallot's tetralogy were reviewed over 3 years after surgery. The average age at surgery was 7.4 years (range 6 months to 37 years). The review included ECG, chest X-ray, echocardiography, exercise stress testing and Holter monitoring, completed by cardiac catheterisation in 10 cases and electrophysiological investigation in 4 cases. Forty-eight of the 59 patients (81.3 p. 100) had no signs of ventricular arrhythmia or only benign ventricular extrasystoles (Group I). Four patients (6.8 p. 100) had severe ventricular arrhythmias (Group II). Seven patients (11.9 p. 100) had one or more episodes of ventricular tachycardia (VT) (Group III) and, in 3 of these patients, VT was recorded during Holter monitoring or exercise stress testing. One patient in Group III died after reoperation, but there were no cases of sudden death in this series. The high risk patients Groups II and III) were operated late (after 5 years), had bi- or trifascicular block (7 out of 11 cases), ventricular extrasystoles on resting ECGs (9 out of 11 cases), cardiomegaly (6 out of 7 cases in Group III), echocardiographic dilatation of the infundibulum (6 out of the 8 patients undergoing echocardiography in Groups II and III). They had significant residual malformation but without right ventricular hypertension (as judged mainly by immediate postoperative data). Ventricular arrhythmias occurred over 6 years after surgery. However, none of the patients operated before 2 years of age had ventricular arrhythmias or VT with a mean follow-up period of 7.5 years, perhaps because LV function was protected.(ABSTRACT TRUNCATED AT 250 WORDS)

[Selective tricuspid annuloplasty without prosthetic support].

Two techniques of plastic surgery are currently used to treat tricuspid insufficiency: a prosthetic reductor or a continuous running suture. In the technique advocated here a double continuous suture is inserted into the tricuspid annulus, one running from the antero-septal to the antero-external commissures and the other, from the postero-septal to the antero-external commissures. When these two sutures are tied separately, the circumferences of the two parts of the annulus, which are diversely dilated, can be reduced. The authors have used this technique in 141 patients and a Carpentier's annulus in 41 patients. Perioperative mortality and 5-year survival were the same in both series, but the incidence of postoperative atrioventricular block was much lower in the first one. Another advantage of the double continuous suture technique is that foreign material is reduced to a minimum.

[Mitral valve replacement with bioprosthesis in children].

Forty seven bioprostheses were used for mitral valve replacement between January 1975 and June 1980, with no operative mortality, in children under 19 years of age. This study was undertaken to evaluate the medium and longterm outcome of 43 patients followed up for at least 2 years. The late mortality was higher in children under 13 years of age (11.1% per patient/year) than in older children (3% per patient/year). The incidence of reoperation for deterioration of the bioprosthesis was 5,5% per patient/year. The actuarial longevity of bioprostheses without any complications was 48 +/- 16% at 5 years. After a review of the literature, the authors discuss their present therapeutic attitude: whenever possible, mitral valvuloplasty is the operation of choice, but when valve replacement is necessary, two criteria must be considered: the age of the patient and conditions of follow up. If medical follow-up facilities are good: mechanical prostheses are preferred in patients under 13 years of age: after puberty especially in girls, the bioprosthesis is the valve of choice. If medical follow-up facilities are poor: the valve of choice is a bioprosthesis at all ages because of the risk of thromboembolism and the relatively slow clinical aggravation in cases of bioprosthetic deterioration.

[Neuroendocrine sarcoidosis: a case].

The authors report a case of neuro-endocrine sarcoidosis, associating panhypopituitarism , diabetes insipidus, and involvement of the optic chiasma with behavioural changes, chronic meningitis and a diffuse pyramidal syndrome. The diagnosis was suggested by the presence of mediastinal lymphadenopathy and confirmed during a surgical procedure to conserve the optic nerves. The clinical course on corticosteroids was unfavourable because of iatrogenic cushing' syndrome and steroid dependence . It was not possible to withdraw steroids, even with the use of immunosuppressors (Methotrexate).

[Treatment of recent traumatic ruptures of aortic isthmus (author's transl)].

We recommand the following procedure: --positionment of the patient allowing the simultaneous approach of left pleural cavity and left femoral vessels. --aortic liberation far away of the isthm, in a diffuse hematoma. --medullar protection by femoro-femoral extra corporeal circulation. --recovery of aortic continuity either by direct suture or by interposition of an prosthetic tube, the sutures being largely supported by mediastinal cellular tissue. We have used this technique in 5 patients, with a good result in all cases.
