[Traumatic rupture of the aortic isthmus revealed by acute obstruction of the descending thoracic aorta].

A traumatic transection of the upper descending thoracic aorta, undiagnosed, was complicated on the tenth day by an acute obstruction of the descending thoracic aorta. The upper body hypertension resulted in generalised convulsions and cardiac failure with pulmonary oedema. The lower body ischemia resulted in paraplegia, acute ischemia of the lower limbs, liver failure and anuria. An emergency revascularisation of the lower body was achieved by axillary-bifemoral bypass. The improvement of the clinical status allowed complete repair of the aortic transection two days after the extra-anatomic revascularisation. This case emphasizes the severity of the cases with impaired blood flow to the lower body and the benefit of the extra-anatomic bypass in pathology of the upper descending thoracic aorta when complete repair of the aortic transection is associated with an extremely high risk.

[Association of cor triatriatum and obstruction of abnormal left pulmonary venous drainage. Apropos of a case].

A case of subtotal cor triatriatum associated with a partial anomalous pulmonary venous drainage of the left lung, in a 30 months old boy is reported. Diagnosis was suggested by the presence of pulmonary venous obstruction and pulmonary hypertension. Doppler, echocardiogram diagnosed the cor triatriatum and the degree of the pulmonary hypertension. The cine-angiography demonstrated the anomalous, obstructive, left pulmonary venous drainage. The pulmonary hypertension has mandatorised an early surgical cure, the result was satisfactory at 16 months.

[Assisted circulation by external heterotopic prosthesis as a bridge to heart transplantation].

Eleven patients aged 7 to 58 years were placed on assisted circulation with Pierce (2 cases) or Abiomed (9 cases) external prosthetic ventricles as a bridge to cardiac transplantation. The indications were terminal cardiac failure following cardiomyopathy (7 cases), decompensated ischemic heart disease (3 cases) and subacute post-transplantation rejection (1 case). The duration of the assisted circulation ranged from 24 hours to 11 days. All patients were transplanted but 3 died after transplantation (27%). The circulatory assistance was satisfactory in all patients as shown by the regression of clinical signs of low cardiac output and the normalisation of diuresis. The complications observed during assisted circulation and after cardiac transplantation were: haemorrhage (36%), infection (27%) and thromboembolism (9%). These preliminary results with a 72% post-transplantation survival rate, show that both systems are effective "bridges to cardiac transplantation". The Abiomen device is excellent value for money and relatively simple to install and represents a good compromise between the sophisticated techniques of circulatory assistance and the problems of the cost of health care.

[Hancock pericardial prosthesis. Intrinsic dysfunctions].

The frequency of primary dysfunction of 432 Hancock pericardial bioprosthesis was evaluated during a mean follow-up period of 53.1 months per patient. This frequency was 3.20% valve-year in mitral valve prosthesis and 0.92% valve-year in aortic valve prosthesis. Only one case of calcification was noted. Dysfunction was usually due to tearing of one or several pericardial cusps (25 cases), occasionally to tissue retraction (4 cases). Pathological examination of the explanted valves showed fibrin formation followed by organization into fibrous tissue in the host, retracting or fragilizing the pericardial valvular tissue. A preliminary study of the same group had led to discontinuation of Hancock prosthesis. The long follow-up period makes it possible to compare the results obtained with those of pericardial prosthesis of the same generation, to stress the need for echocardiographic monitoring of the implanted valves and to hope that new techniques of pericardial valve fitting will improve the mechanical reliability of prosthesis which, from the point of view of thrombogenesis and haemodynamics, have unquestionable advantages.

[Brucella endocarditis caused by reinfection of an aortic Starr valve. Apropos of a case with a favorable development after valvular replacement].

We report the case of a 36-year old male patient who was admitted for subacute endocarditis on an aortic prosthetic valve implanted 14 years previously for endocarditic valve regurgitation; no pathogen had been isolated at that time. Nine blood cultures were positive for Brucella abortus. The conventional antibiotic therapy did not prevent the formation of an abscess below the aortic annulus. A third antibiotic combination (quinolone and rifampicin) resulted in pyrexia prior to surgery. An atrioventricular block initially noted raised the problem of an associated myocarditis. The risk of Brucella infection existed before the first operation, and five serological tests were positive for that organism between the two episodes, which makes reinfection highly probable. This is the third case of Brucella endocarditis on a prosthetic valve. Its originality lies in its mechanism.

[Valve-fitted prosthetic tubes in the pulmonary outflow tract. Results of a series of 45 operations].

The malformations requiring valve fitted prosthetic tubes in the pulmonary outflow tract were mainly persistent truncus arteriosus and pulmonary atresia with ventricular septal defect in this series. The surgical mortality before 18 months was 75% and 19% after this age. The long-term clinical result (average follow up period: 2,5 years) was good or acceptable in 20 of the 32 survivors. There were 5 late deaths and 6 reoperations. The main causes of long-term failures were progressive pulmonary hypertension without shunt, acquired stenoses on the prosthesis and late infection. It is important to assess poor results by catheterisation as reoperation is frequently possible with a relatively low mortality rate (1/6) and encouraging results.

[Pulmonary stenosis with tricuspid insufficiency in the child].

The authors report 3 cases of pulmonary stenosis with an intact interventricular septum and tricuspid incompetence. The tricuspid regurgitation was corrected in all 3 cases. After recalling the clinical features, they emphasize the importance of seeking for this condition and correcting it in every case if the immediate and long-term results are to be satisfactory.

Early recovery of albumin synthesis after liver transplantation.

The delay necessary for an orthotopic transplanted liver to recover in normal activity has never been defined. This is of great importance whenever liver transplantation is considered in patients with severe liver insufficiency. This delay was studied in dogs using albumin synthesis and BSP clearance as tests of liver function. Albumin synthesis was normal as early as 2 h following graft revascularization while BSP clearance was not yet normal by this time. It is suggested that transplanted livers will be rapidly able to corect metabolic disorders and above all coagulation problems in patients with terminal hepatic failure.

[Septal perforation of myocardial infarct. Progress and limitation of current treatment. Apropos of 28 recent cases].

The emergency treatment of septal perforation in a myocardial infarction was markedly improved by pre-operative preparation of the patient by an intra-aortic balloon. If one excludes 7 cases in which the favourable immediate course made possible a delayed operation, 21 cases, severe from the start, were observed in the last two years: 8 patients, were thought to be operable with 6 successes. The type of the patient, the age, the associated diseases, the gravity and extension of the local lesions explain that this complication nevertheless still remains very often beyond the present possibilities of the medical-surgical treatment.

Primary endotheliosarcoma of the thoracic aorta.

A case of thoracic aortic endotheliosarcoma is reported. The diagnosis of an endothelial neoplasm was confirmed by ultrastructural study and the use of cell markers: Antigene VII, Antigene H and a Lectin: Ulex Europaeus 1. The macroscopic aspect was particular. There were buds on the aortic intima. The tumor growing along the intimal surface, had invaded and destroyed the vascular wall. There was a stenosis of the origin of the innominate artery and a total obstruction of the left subclavian artery.
