[Compressive hemopericardium of the right atrium after cardiac surgery].

Between June 1983 and September 1984, 3 patients operated for mitral valve disease presented with acute right heart failure due to right atrial compression. Emergency echocardiography did not show pericardial separation around the ventricles but in the apical 4 chamber view severe right atrial compression by an extracardiac mass was observed. Emergency surgery was performed in all three cases to evacuate a localised haemopericardium despite the absence of pericardial fusion.

Comparative evaluation of aortic valve replacement with Starr, Björk, and porcine valve prostheses.

Three groups of 100 consecutive patients with aortic valve disease who were operated on between 1974 and 1978 underwent long-term evaluation. There were 100 aortic valve replacements with porcine bioprosthetic valves (group I), 100 with Starr valves (group II), and 100 with Björk valves (group III). There were no significant differences in the preoperative clinical conditions of the patients in the three groups.

[Reoperation on valve bioprostheses. Apropos of 64 cases].

Sixty-four patients with one or more bioprostheses were reoperated between 1970 and 1982. Reoperation was performed for degenerative lesions in cases (48%), for aseptic periprosthetic leaks in 18 cases (28%), for infectious lesions in 13 cases (21%) and for thrombosis in 2 cases (3%). Degenerative and infectious lesions were commoner in aortic bioprostheses whilst periprosthetic leaks were commoner in mitral bioprostheses.

[Long-term outcome of bioprostheses].

The major advantage of cardiac bioprostheses, apart from the good haemodynamic performance of recent models, is that they are not thrombogenic, so that the patient does not have to follow a life-long anticoagulant treatment. However, their major disadvantage, in comparison with the mechanical prostheses, is that they deteriorate over time. This study defines the durability of bioprostheses over the first seven years and beyond seven years.

[Comparative evaluation of various methods of treatment of mitral valve diseases. Apropos of 4 series of 100 patients operated on using the Starr prosthesis, Bjork prosthesis, bioprosthesis and valve reconstruction].

The results of 4 groups of 100 patients undergoing mitral valvuloplasty (group I), isolated mitral valve replacement by a bioprosthesis (group II), a Starr-Edwards prosthesis (group III) and a Björk prosthesis (group IV) between 1974 and 1977 were compared. The selection of patients for each group was identical and made according to strict criteria. The average age was between 47.

[Calcified aortic stenosis and coronary disease. Apropos of 115 surgically-treated cases].

The authors studied 115 surgical cases of calcific aortic stenosis (AS) with coronary angiography. Between 1970 and 1981, 56 of these patients also had one or more aortocoronary bypass grafts (ACBG) (Group I). The other 59 cases, recruited from 1978 to 1981, comprise the control group who underwent isolated aortic valve replacement either with a normal coronary angiogram (Group II: 50 cases) or with such extensive coronary artery disease that ACBG was impossible (Group III: 9 cases).

[Percutaneous endoluminal angioplasty of the supra-aortic arterial trunks. Immediate and remote results].

Twelve tight stenoses (9 of the subclavian artery, 1 of the axillary artery and 2 of the brachio-cephalic artery) were dilated with immediate satisfactory results in all cases. Only one complication (regressive lesion of the median nerve) was recorded. Eight patients were followed-up for a mean period of 13 months: all were symptom-free, and digital angiography by the intravenous route showed a stable image of patency.

[Tricuspid reoperation in the surgery of rheumatic valve diseases. Apropos of 24 cases].

Twenty four patients were reoperated on the tricuspid valve alone between 1967 and 1981. The first operation had been performed for mitral valve disease and consisted of 23 mitral valve replacements and one commissurotomy associated with two aortic valve replacements. The surgical decision with regard to the tricuspid valve at the initial operation had been abstention (10 cases), tricuspid valvuloplasty (10 cases) and tricuspid valve replacement (4 cases).

[Comparison of quantitative data from two-dimensional echocardiography and anatomical examination in mitral stenosis].

This prospective study was undertaken to assess the results of 2D echocardiography in the assessment of valvular and subvalvular lesions in mitral stenosis. The echocardiographic findings (E) were compared with peroperative and laboratory anatomical examination of the excised valve (A). The following criteria were compared: 1) planimetry of mitral valve surface area, 2) mobility of the anterior leaflet, assessed anatomically by the flexibility of the tissue, and echocardiographically by the amplitude of early diastolic excursion, 3) length of anterior and posterior leaflets, 4) presence of calcification, 5) length of the longest tendinae chordae, measured from the papillary muscle to the insertion of the valve, 6) thickness of the thickest tendinae chordae attached to each leaflet.

[Mitral insufficiency complicating idiopathic subvalvular aneurysm of the left ventricle. Apropos of 5 surgical cases].

The surgical team of Pr Ch. Dubost operated 5 cases of idiopathic subvalvular left ventricular aneurysm with associated mitral incompetence over a 6 year period (from 1976 to 1981). These 5 cases closely resemble Abraham's et al's classical description of "annular subvalvular left ventricular aneurysms".

[Bridge grafting between the ascending and lower thoracic aorta using the right side approach (author's transl)].

We describe a method aimed at reconstituting the thoracic aorta by means of a graft located on the right side of the heart. The method is original in that the graft is entirely intra-thoracic and not thoraco-abdominal, as in previously reported similar operations, its advantages are demonstrated by reference to one case where it was used for the treatment of a relapsed congenital atresia of the aortic arch.
