[Surgery of endomyocardial fibrosis. Apropos of 32 cases].

From 1971 to 1984, 32 patients with endomyocardial fibrosis (EMF) were treated by endocardial resection (decortication) and valve replacement. The population consisted in 20 men and 12 women (age ranged from 8 to 64); 19 patients were european and 13 african. All were symptomatic, 78 p. 100 in stages III or IV of the NYHA. Hypereosinophilia was detected in 21 patients and its cause was determined in 11 cases. Cardiac involvement was biventricular in 22 patients and monoventricular in 10 patients. Six patients died in the immediate postoperative period and 6 late deaths were observed, owing to extracardiac causes in 4. There were no recurrence of EMF. Despite a high mortality rate, the authors suggest that all symptomatic EMF should benefit from endocardial resection.

[Treatment of type A aortic dissection by exclusive glueing].

From 1984 to 1990, 24 patients suffering from type A aortic dissection were treated by directly suturing the entry orifice of the dissection and glueing (gelatin-resorcin-formaldehyde glue) the dissected aortic tunicae, without any prosthetic replacement. Associated aortic insufficiency in 21 patients was treated by valve replacement (8 patients) or plasty (8 patients). Deep hypothermia with circulatory arrest was required in 13 patients, whose aortic arch was involved by the dissection. All patients survived the operation. All these patients were followed up from 6 to 60 months. All were controlled with Doppler echography. In addition, 21 of them were examined with angiography, 17 with CT and 5 with MRI. 21 patients had an ascending aorta and an apparently normal aortic arch. Limited dissection of the descending aorta, requiring no second surgery, was noted in 2 patients. Persisting dissection of the descending aorta was present in 13 patients. Valve replacement was necessary 18 months later in 1 patient. Heart transplantation was necessary 14 months later in a patient suffering from associated cardiomyopathy. These results demonstrate that aortic glueing is effective and safe in the middle term for the treatment of aortic dissection.

[Benign tumors of the heart (excluding myxoma). Experience with 9 surgically treated cases].

Benign non myxomatous cardiac tumors are rare. Between 1968 and 1988, 9 patients presenting benign non myxomatous cardiac tumors were operated in our institution. Tumors were: 2 rhabdomyomas, 2 lipomas, 2 fibromas, 1 pheochromocytomas, 1 mesothelioma and 1 papillary fibroelastoma. Total excision was possible in all cases but one (multiple fibromas). We hereby present a review of the literature on the subject. We focalize on the new imagery techniques in order to help the diagnosis and on the new surgical possibilities (cardiomyoplasty) which make possible complete surgical excision.

Primary liposarcoma of the heart.

We report the eleventh illustrated case of primary liposarcoma of the heart in a 28-year-old man. The tumor arose from the mitral valve and the left ventricle and was revealed by a solitary brain metastasis 1 year before. The primary tumor and the metastasis were surgically removed. The cardiac and brain neoplasms were myxoid liposarcoma, as confirmed by histochemical, immunohistochemical, and ultrastructural studies. Although review of the literature points out the poor survival of patients with malignant liposarcoma of the heart, no recurrence or metastasis was observed after a 6-month follow-up.

[Arterial injuries caused by the insertion of an intra-aortic counterpulsion balloon].

Insertion of an intra-aortic counterpulsion balloon was necessary following 283 surgical procedures with the heart pump at Hospital Broussais. One instance of vascular trauma at the site of insertion of the balloon was reported in 36 cases (13 p. cent). This was treated according to the severity of the arterial lesion with the following techniques: closure with Goretex venous patch (n = 25), short ilio-femoral by-pass (n = 9) and extra-anatomical femoro-femoral by-pass (n = 2). The overall mortality of the patients who required an intra-aortic balloon was 19 p. cent, including one case of retrograde aortic dissection at the site of insertion of the balloon. The morbidity related to the insertion of the balloon was as follows: one leg amputation, two disabling intermittent claudication episodes.

[Treatment of type A aortic dissection by exclusive gluing. Long-term results apropos of 15 patients].

Between 1984 and 1988, 15 patients with a type A aortic dissection were treated with direct suturing of the entry opening of the dissection and gluing of the dissected aortic layers using the GRF glue (gelatine-resorcine-formaldehyde), without prosthetic replacement. An associated aortic insufficiency, in 10 patients, was treated with valve replacement (5 patients) or plasty (5 patients). Deep hypothermia with circulatory arrest were necessary in 10 patients whose dissection reached the ascending aorta. All patients survived the procedure. These patients are followed from 6 to 44 months. They are all controlled by echo-Doppler. In addition, ten had an angiography, 6 a control scan and 5 a NMR. In twelve patients, the ascending aorta as well as the aortic junction are normal. A limited aortic dissection which did not require a secondary procedure, is found in 3 patients. A dissection of the descending aorta is present in 10 patients. Two patients had to be re-operated: one, for a valve replacement, 18 months later; the other, for a myocardiopathy at the terminal stage, 14 months later, requiring an orthotopic transplantation. These results show that gluing of the aorta is an easy and effective treatment in type A aortic dissections.

Valve repair with Carpentier techniques. The second decade.

Among 206 consecutive patients having undergone mitral valve repair with a prosthetic ring between 1972 and 1979 in our institution, the 195 patients (94.5%) who survived the operation were studied to assess the long-term function of this method of repair. Patients' ages ranged from 18 to 79 years (mean age 48.7 years). Mitral valve insufficiency was due to degenerative disease in 113 patients (58%), rheumatic disease in 74 (38%), ischemia and other causes in eight patients (4%). A total of 188 patients (9.7%) were in New York Heart Association class III or IV preoperatively and 94 (48%) had atrial fibrillation. The patients were divided into three functional groups: type I (normal leaflet motion), 35 patients (18%); type II (leaflet prolapse), 147 patients (75%); and type III (restricted leaflet motion), 13 patients (7%). The techniques included prosthetic ring annuloplasty (185 patients), leaflet resection (158 patients), chordal shortening (89 patients), leaflet mobilization (10 patients) and papillary muscle reimplantation (2 patients). Long-term follow-up was available in 189 patients (96.8%), for a rate of 2316 patients per year. The 15-year actuarial and valve-related survival rates were 72.4% and 82.8%, respectively. At 15 years, 93.9% of the patients were free from thromboembolism, 96.6% free from endocarditis, 95.6% free from anticoagulant-related hemorrhage, and 87.38% free from reoperation. Actuarial rate of freedom from reoperation was higher in the group with degenerative disease (92.7%) than in the group with rheumatic disease (76.12%). Among the 157 survivors, 117 (74%) were in New York Heart Association class I and class II and 105 (66%) were in sinus rhythm. Doppler echocardiographic studies showed normal ventricular contractility in 134 patients (84.5%), absence of mitral regurgitation in 112 (74%), trivial regurgitation in 27 (17%), and significant regurgitation in 4 patients (2.5%).

A 10-year comparison of mitral valve replacement with Carpentier-Edwards and Hancock porcine bioprostheses.

Two hundred fifty-three patients who underwent isolated mitral valve replacement with a porcine bioprosthesis had long-term evaluation. One hundred forty-seven patients received a Carpentier-Edwards porcine bioprosthesis and 106, a Hancock valve. There were no significant differences in preoperative clinical characteristics between the two groups. Cumulative follow-up was 1,375 patient-years. At 10 years, 93% +/- 2.5% of the patients in the Carpentier-Edwards group and 85% +/- 7.8% of those in the Hancock group were free from valve-related death (not significant), and 95% +/- 2% and 91% +/- 3.8%, respectively, were free from thromboembolism (not significant). At 10 years, 65% +/- 7.2% of the patients in the Carpentier-Edwards group and 66% +/- 7.2% of those in the Hancock group were free from structural valve deterioration (not significant), and 64% +/- 6% and 59% +/- 7.3%, respectively, were free from reoperation (not significant). We conclude that the first generation of Carpentier-Edwards and Hancock prostheses produce comparable long-term results in the mitral position.

[Postoperative iatrogenic coronaro-ventricular fistula].

Acquired coronary cardiac fistulas are rare. To date, thirty cases have been published in the literature, all secondary to thoracic trauma. The right cardiac chambers were more frequently involved. A recent continuous cardiac murmur is the most constant finding. Nontreated, these lesions tend to induce coronary insufficiency and congestive heart failure. 22 of the 30 reported cases were managed surgically. We hereby report a case of postoperative coronary cardiac fistula secondary to left ventricular venting, in which the fistula involved the left ventricular cavity.

[Endomyocardial fibrosis].

Since the first case of endocardial resection I have performed in 1971, many similar cases have been operated on in the world, principally in Equatorian areas such as Africa, Northeastern Brazil and Southern India. In caucasian race, cases are less frequent but are similar to the other ones: in fact, endomyocardial fibrosis which was described by Davies in 1948 in Africa and Löffler's fibroplastie endocarditis, associated with hypereosinophylia (1936) are similar and respond to the same treatment. Our purpose in this paper is to present the long term results of the 34 cases operated at the Broussais Hospital in Paris since 1971. There were 21 males and 13 females, mean age 32 years (8 to 64), 22 were caucasians, 12 black africans. The sites of resection were 8 right ventricular, 4 left and 22 biventricular. Valve replacement was monovalvular in 11 cases and bivalvular in 23, mainly with bioprostheses. There were 7 early deaths and 6 late deaths, 2 after 30 months and 4 after 45, 60, 84, 85 months; only 2 of them were due to cardiac causes. We have not observed any case of recurrence. All surviving patients were in class I/II of N.Y.H.A. despite the fact that 4 have had valvular replacement due to alteration of the bioprosthesis.

[Experience at an Internal Medicine service in the postoperative follow-up of 403 patients operated on at a cardiovascular surgery service].

Over the last 3 years, 403 patients operated in the Department of Cardiovascular Surgery of Broussais Hospital have been transferred to a Department of Internal Medicine for secondary postoperative care. A total of 245 non-cardiac complications (64%) and 134 cardiac or vascular complications (36%) were observed in 321 of these 403 patients (80%). Infections accounted for 26% of non-cardiac complications (63/245). They included 9 cases of mediastinitis, 2 cases of septicemia, 6 endocarditis, 6 wound infections, and 40 other infections (ENT, gastrointestinal, pulmonary, urogenital). The non-cardiac, non-infectious complications comprised mainly delayed healing (39 cases) and pleuropulmonary (29 cases), ENT (9 cases), gastrointestinal (31 cases), urogenital (12 cases), hematological (17 cases) and neuropsychiatric (9 cases) complications; and, finally, 37 inflammatory syndromes. The cardiac complications were pericarditis with or without tamponade (24 cases), arrhythmias or conduction disturbances (50 cases), haemodynamic (54 cases) and vascular (6 cases complications. These very varied complications sometimes occurred late and could be latent. They resulted in prolongation of the duration of hospitalization, so increasing the overall health costs.

Use of surgical glue without replacement in the treatment of type A aortic dissection.

Between 1984 and 1988, 15 patients with type A aortic dissection were treated by direct suturing of the intimal tear and extensive sticking of the dissected aortic layers with surgical (gelatin-resorcin-formaldehyde) glue without prosthetic graft replacement. Aortic incompetence was present in 10 patients, a situation that required valvular replacement in five and valvular repair in five. In 10 patients, the dissection extended to the transverse aortic arch, requiring profound hypothermia and circulatory arrest. All patients survived the operation. Follow-up ranged from 6 to 44 months. All patients were monitored by Doppler echocardiographic studies. In addition, 10 underwent angiography; six, a computed tomographic scan; and five, magnetic resonance imaging. In all patients but two, the ascending aorta and transverse arch had a normal appearance. In three patients, a limited dissection persisted that did not require reoperation. Dissection of the descending aorta was present in 10 patients. One patient required a valvular replacement 18 months after surgery, and one underwent heart transplantation for an associated cardiomyopathy 14 months after surgery. These preliminary results indicate that surgical glue can be used safely and efficiently in type A aortic dissection as an alternative to aortic replacement.

Clinical comparison of mitral valve replacement using porcine, Starr, and Bjork valves.

The choice of a cardiac prosthesis for mitral valve replacement remains controversial, and thromboembolic complications are still a major cause of morbidity and mortality in patients with mechanical valves. Because of this, permanent anticoagulation with its risks and constraints on daily life is necessary. Bioprostheses, however, are associated with a lower rate of thromboembolic events. Therefore, the need for long-term anticoagulation is minimized. These advantages are counterbalanced by the limited durability of tissue valves. In an effort to give some perspective to this balance, we compared the long-term results of three commonly used mitral valve prostheses. Three hundred patients operated on in the same institution January 1974 to December 1978 form the basis of this evaluation.
