[Dwarfism and constrictive pericarditis. Apropos of a case of so-called Mulibrey dwarfism with hypereosinophilia].

A child of 10 was admitted to a cardiology unit with adiastole. The marked degree of dwarfism and anatomical features were characteristic of the so-called 'Mulibrey' dwarfism. Surgical intervention confirmed the constrictive pericarditis which is normally found in this condition. Unfortunately, the adiastole persisted which, taking into account the marked eosinophilia, made an associated endomyocardial fibrosis seem likely. The distinctive features of constrictive pericarditis and of the constrictive type of cardiomyopathy are recalled.

[Pathological data of 92 rheumatic mitral valve after surgical ablation : comparison with pre-operative echocardiography results].

The echocardiographic information obtained pre-operatively with an electronic linear scanning system (Multiscan) was compared with the results of pathological examination of the excised mitral valve in 92 patients, and showed a close correlation. The way in which the pathological changes influence the various parameters usually used to distinguish this type of rheumatic valvular disease is demonstrated. Two-dimensional imagery provides precise information : this is shown by comparison of the still frames of the videoscopic recording and the photographs of the corresponding pathological specimens. Valve thickness, length and thickness of the chordae, calcification, mitral valve surface and commissural separation are well shown, especially at the anterior leaflet. Study of transverse incidences seems the most reliable method of estimating mitral valve area. Systolic separation of mitral valve echos, according to the usual criteria, is a good sign of associated mitral incompetence and was found in 83% of cases of mixed mitral valve disease. The mean values of anterior mitral leaflet excursion, diastolic slope and opening speeds were compared in three groups of mitral stanosis with preferential antatomical features and a control group of pure mitral stenosis with supple valves. No individual parameter was found to be specific for a particular antatomical feature, showing multiple correlations to be indispensable. The difficulty of diagnosis by isolated traditional echocardiography is confirmed and the association of two dimensional imagery would seem essential not only in making the diagnosis but also in the pre operative work up.

[Resections of the left ventricle in the surgical treatment of parietal sequelae of myocardial infarct].

Resection of left ventricular tissue seems to be playing an increasing part in the treatment of the sequelae of myocardial infarction. In a total of 700 patients who underwent surgery for some aspect of coronary atherosclerosis, 40 underwent resection of left ventricular tissue. In the majority of cases, diagnosis rested on left ventricular cine-angiography and in 3 cases this had to be carried out as an urgent procedure with circulatory assistance using diastolic counter-pressure (DCP) from an intra-aortic balloon. A selective contrast technique for the two coronary arteries was used whenever possible. The surgical anatomy of the lesions indicates a difference between a localised dyskinesia and diffuse dyskinesia, the latter having a severe effect on left ventricular function. In a group of localised dyskinesias, the territory supplied by the anterior descending artery was by far the most frequently affected. Resection of left ventricular tissue was associated with a myocardial bypass revascularisation procedure in 9 cases, valve repair in 7 cases, and closure of a septal perforation in 3 cases. The total inpatient mortality rate is still quite high (23.1%) because of the severity and widespread nature of the coronary disease. However, the mid-and long-term results are good, the criteria being functional improvement and the actuarial 4-year survival rate.

[The "small aortic ring." Hope for a surgical solution].

The "small aortic ring" was until recently an unresolved problem for surgeons operating on the aortic valves. It used to contraindicate valve replacement in the child, and sometimes led to the insertion of too small a valve in the adult. Some hope of a solution has appeared in the form of three new techniques: enlargement of the aortic ring over the mitral valve, aorto-ventriculoplasty, and apico-aortic shunt. Two adults have had the ring enlarged above the mitral valve with good results in both cases. Five children have had an aorto-ventriculoplasty with good results in two cases, post-operative atrio-ventricular block in one, and two deaths, one early and the other late. These deaths appear to be more closely related to the severity of the initial lesion and to the degree of decompensation of the myocardium than to the operation itself. There are advantages and problems with this technique. An attempt has been made to systematise indications for treatment as a function of the lesions and the state of the patient.

[Mitral replacement using a ball-valve prosthesis under hypothermic protection of the myocardium. 230 cases].

A series of 230 mitral valve replacements using exclusively the Starr-Edwards ball valve prosthesis is presented. These 230 patients underwent surgery over a 4 year period, a uniform operative technique being used. Its essential feature was the use of a standardised technique for protection of the myocardium based upon continous clamping of the aorta and deep hypothermia at around 15 degrees. The technique of myocardial hypothermia, already reported, is briefly reviewed. The results are analysed, in the short and long term. Overall hospital mortality was 6.9 per cent, including multiple valve replacements and combined coronary surgery. The total number of thrombo-embolic complications was 8, including 1 early thrombosis out of 230 patients - i.e. 0.4 per cent and 7 late thrombo-embolic episodes out of 180 patients followed up for 1 month to 4 years - i.e. 3.8 per cent. Secondary and late mortality was 11 cases out of 180 patients. The survival rate at 4 years was 78 per cent by actuarial calculation, including operative mortality. These results justify the continued use of ball prosthesis, the long term thrombo-embolic risks of which are equal to or less than those of disc prosthesis, and the resistance of which to wear and tear is shown by the long postoperative survivals.

[Early neurological complications after cardiac surgery under ECC].

A non-trifling frequency (3,3 p. 100) of neurologic complications is observed after surgery under E.C.C. The part of some factors has been analysed and discussed, especially those played by the type of the system used, quality of the E.C.C., and the patients' conditions. Many problems are still unresolved. The actual gravity of observed troubles must bring a better harshness in preventive treatment, and to a more adjusted treatment when these troubles are noted.

[Proteins and blood volume after cardiac surgery under ECC and hemodilution].

The variations in protein, bodyweight and circulating blood volume during operation are studied in 18 patients operated under ECC. The frequency of hypovolemia with hypoproteinemia and over hydration of the interstitial medium is confirmed. The prolongation of ECC beyond 120 minutes is accompanied by a considerable reduction in the plasma sector. The frequency of hypovolemia must render the use of diuretics prudent. The existence of hypoproteinemia and interstitial overload suggests the value of albumin perfusions.

[Membrane oxygenators in cardiac surgery: progress].

This study tries to define if the membrane oxygenators are available during cardiac surgery under E.C.C., and if their performance are superior to those of conventional oxygenators. Two series of research are done. In the first one, we compare performance of two membrane oxygenators: the Rhône-Poulenc heart-lung machine (10 cases) and the Travenol TMO Teflo machine (100 cases). The general impression is good: the two proposed systems seem to be perfectly well adapted to surgical utilization conditions, avoiding excessive ventilations and eventually allowing to keep on E.C.C. in postoperative. In the second part of this work, two series of patients are studied, one oeprated under membrane oxygenator (Teflo), the second under bubble oxygenator (Bentley Q 100). Comparative study shows small differences between the two groups. Only the post-operative enzymatic profile is clearly for the membrane oxygenator which also insure a waking and a postoperative recovery of highest quality. These first observations justify to keep on using of membrane oxygenators in cardiac surgery.

[Protection of the myocardium by hypothermia during extracorporeal circulation. Experimental and clinical study].

Hypothermic protection of myocardia during E.C.C. has been estimated on a 35 dogs experimental series and on a clinical series of 700 acquired cardiopathies of adult, including 400 valvular replacements and 300 aorto-coronary by-pass. Experimental results have been estimated by biochemic and morphologic controls done on myocardic samples took up by drillbiopsy. The biochemical study includes among others a dosing of the high-energy phosphorus compounds (P.C. and A.T.P.). Morphological study was done by optic and electronic microscopy. Results made clear the superiority of the hypothermic ischemia at 10 degrees C on the continued perfusion at 32 degrees C with fibrillative heart. An hypothermic protection method with successively cold perfusion of the coronary system and a heart immersion in a salted solution at 4 degrees C has been utilized during valvular and coronary surgery on human in 700 cases. The total mortality was of 5,8 p. 100. The rate of post-operative infarcts was 2,4 p. 100. Incidence of intra-ventricular conduction troubles has been 1,1 p. 100. There was no relation between mortality and morbidity of myocardic origin and the lasting of the ischemic clamp, which were of 21 mn up to 165 mn. The low incidence of complications of myocardic origin is due to the hypothermic protection of the myocardia.

[Aortopulmonary fistula with interventricular defect and pulmonary valve stenosis in a 15-year-old girl. Surgical correction].

A young girl of 15 with an aorto-pulmonary fistula was treated surgically, with a successful outcome. The clinical diagnosis could only be established at right-sided catheterisation, and especially at retrograde per-arterial aortography. The small size of the fistula explains the low level of the pulmonary arterial hypertension, and the way in which the condition was well-tolerated for some time. The association of this lesion with ventricular septal defect and pulmonary stenosis is extremely rare.
