[Surgical management of cardiac wounds: cardiac or general surgical service?]. / Plaies du coeur, prise en charge de chirurgie cardiaque ou générale?

OBJECTIVE: To define modalities of cardiac wound management with a special emphasis on the initial direction of the patient toward a surgical service, rapid diagnosis, and surgical treatment. METHOD: Sixteen patients with thoracic injury to the region of the heart treated between 1996 and 2006 were evaluated retrospectively. Pre-operative clinical data, echography, and CT results were collected; time elapsed between injury and treatment, type of surgical treatment, use of cardio-pulmonary bypass, morbidity and mortality were evaluated. RESULTS: There were 16 patients (12 men); age ranged from 18 to 80 with an average of 45.7 years. Nine patients had penetrating cardiac wounds, two had blunt trauma, and five suffered iatrogenic trauma. Cardio-pulmonary bypass was used in two cases. The mean time elapsed between trauma and surgical evaluation was 63 minutes (p=0.18). In all cases, surgery consisted of a myorraphy without coronary or valvular repair. Post-operative complications occurred in 4 patients (25%) and resulted in 2 deaths (12.5%). Complication and death were associated with a prolonged interval between injury and surgical management. CONCLUSION: Patients with cardiac wounds should be transported to the nearest surgical hospital. There are no benefits to cardio-pulmonary bypass in cardiac trauma.

Vacuum-assisted closure in the treatment of poststernotomy mediastinitis in the paediatric patient.

INTRODUCTION: Delayed sternal closure after paediatric open heart procedure is often necessary. The risk of delayed sternal closure is infection: superficial wound or sternal and mediastinal infection. The incidence of sternal wound infection reported in the literature varies from 0.5 to 10%. The mortality for poststernotomy deep sternal infection continues to be high--from 14 to 47%. Established treatment includes surgical debridement, drainage and irrigation, antibiotics, frequent change of wound dressing and direct or secondary closure with omentum or pectoral muscle flap. PATIENTS AND METHODS: Between October 2003 and August 2005, three children, aged from 9 days to 2 years and who had developed severe mediastinitis after cardiac surgery were treated with the vacuum-assisted closure (VAC) system. RESULTS: The duration of VAC treatment ranged from 12 to 21 days. The response to VAC was rapid with local purulence and C-reactive protein (CRP) both decreasing within 72 h in all cases. After good granulation was obtained, two patients required a thin skin graft. DISCUSSION: All three children had peritoneal dialysis which did not permit omental use. The use of pectoralis major is a difficult technique in neonates and the haemodynamic conditions were poor in our cases. The VAC technique is a good indication in post-cardiotomy mediastinitis in children: it plays a role in the reduction of infection and provides good healing.

[A monocenter experience of ventricular septal defects treated by catherization]. / Expérience monocentrique de la fermeture par cathétérisme interventionnel des communications interventriculaires.

INTRODUCTION: Studies on ventricular septal defects closure by catheterization confirm its feasibility without reporting clearly the indications and difficulties encountered. PATIENTS AND RESULTS: From 2001 to end-2006, 22 patients benefited from 26 ventricular septal defects closure (15 muscular and 7 membranous) at a median age and weight of 2.1 years and 12.5 kg, respectively. A perventricular catheterization was performed in 2 cases. Eighteen patients (82%) benefited from 21 prostheses with success. The closure was associated to surgery in 9 cases (41%) whereas it substituted surgery in the other 13 cases (59%). The median duration of the procedure was significantly longer in case of muscular ventricular septal defects (215 min (175-510) vs. 170 min (120-225), p=0.04). Major complications are reported in 5 cases out of 26 catheterization (19%), including one death related to conduction block, occurring after the implantation of two prostheses in a patient with aortopulmonary transposition. All other associated cardiac diseases have been corrected. A prosthetic emboli occurred in one case, 1.5 months after implantation. It had been retrieved by catheterization. Two patients died afterwards from non-procedure-related causes. After a median follow-up of 1.1 years, the 17 other patients remained asymptomatic. One child with a perimembranous prosthesis presents a paroxystic atrio-ventricular block. CONCLUSION: Even though indispensable for the curative treatment of several congenital cardiac diseases including non-operable ventricular septal defects, this procedure is related to a substantial rate of mortality and morbidity. The risk of atrio-ventricular block must be adequately considered in case of membranous ventricular septal defects.

[Long-term results of complete atrio-ventricular canal correction]. / Résultats à long terme du traitement chirurgical du canal atrioventriculaire complet.

OBJECTIVES: To assess the prognosis of surgically corrected complete atrio-ventricular canal and determine risk factors for death and redo surgery. PATIENTS: and method: From January 1984 to March 2006, 126 patients were distributed in 3 groups according to their date of intervention: group I (1984-1991), group II (1992-1999) and group III (2000-2006). They were operated at mean age of 8.35 + 13.3 months. Down syndrome was present in 99 patients (79%). A partial or total closure of the left atrio-ventricular valvular cleft was performed in 47 patients (37%). RESULTS: The in-hospital mortality was at 14.28% (18 patients), including 23.7% in group I, 16.2% in group II and 4.4% in group III (p=0.06). The predictive factors of survival were the Down syndrome (p<0.05) and surgery of the left atrio-ventricular valvular cleft (p=0.05). An early reoperation was required in 6 cases, for a severe leak of this valve (n=4) or an important residual shunt (n=2). After a mean follow-up of 9.5+6.9 years, the survival rate was at 83.6% and 10 patients (9.9%) had a redo surgery for a leak of the left atrio-ventricular valve (n=6) or sub-aortic stenosis (n=4). The rate of no-redo surgery for valve insufficiency was at 94.2% at 5 years, 91.1% at 10 years and 87.6% at 15 years. CONCLUSION: The surgical treatment of complete atrio-ventricular canal became more and more efficient with poor rates of mortality and redo surgery during these last years. The closure of the left atrio-ventricular valve cleft, mostly partial, is frequently performed. Patients with the Down syndrome have a better vital prognosis and lower rates of long-term redo surgery.

[Rehabilitation of hypoplastic pulmonary arteries in pulmonary atresia with ventricular septal defect. Medium term results]. / Réhabilitation des artères pulmonaires hypoplasiques dans l'atrésie pulmonaire avec communication interventriculaire. Résultats à moyen terme.

The treatment of pulmonary atresia with ventricular septal defect, hypoplasia of the native pulmonary arteries and major aorto-pulmonary collaterals is controversial with a wide range of options from symptomatic treatment to surgical correction, but usually unifocal surgery. However, the collateral vessels used in the reconstruction are often tortuous and stenosed, resulting in a problematic haemodynamic result. The authors report the results of medico-surgical rehabilitation of the native pulmonary arteries in three stages. Since 1990, patients with an average Nakata index of 27.5 +/- 16.7 mm2/m2 underwent elective surgical connection of the native pulmonary arteries to the right ventricle (1st stage) followed by their rehabilitation with catheter occlusion of the collaterals (2nd stage) with the aim of preparing surgical correction (3rd stage). The first surgical stage at an median age of 5 months (0.1 to 25.2) was complicated by one death. After an average of 2.1 +/- 1 catheterisations, 17 patients underwent surgical correction at an median age of 2.18 (0.6 to 10.3) years with an average Nakata index of 207 +/- 91 mm2/m2. All survived surgery with three late deaths in patients with poor haemodynamic results (right ventricular/left ventricular pressure ratio>80%). After an median follow-up of 9.2 (3.5 to 17) years, the 14 survivors are in NYHA Class I or II with a good haemodynamic result in 10 patients. The authors conclude that despite some late deaths and raised right ventricular and pulmonary artery pressures in a minority of patients, the rehabilitation of the pulmonary arteries is an effective management of this cardiopathy.

[Medium and long-term results of anatomical correction of transposition of the great arteries in Marseille]. / Résultats à moyen et long terme de la correction anatomique de la transposition des gros vaisseaux à Marseille.

The object of this study was to evaluate the results of anatomical correction of transposition of the great arteries (TGA) in an inter-regional centre. The characteristics of 220 patients operated between 1985 and 2002 were analysed. Prenatal diagnosis of TGA was made in 38 patients (17%) including 36 of the 109 patients operated since 1995 (33%) and leading to earlier atrial septostomy in this situation (p= 0.046). Since 1995, the global early mortality of 12.3% has been significantly reduced to 5.5% (N= 6) including 4.4% (3/68 cases) of simple TGA (p= 0.002). In multivariate analysis, the only independent risk factor for early mortality was the occurrence of a major per-operative complication (p< 0.0001). The average follow-up was 4.8 +/- 4.5 years with an 86% survival at 5, 10 and 15 years and 97% survival at 5 years for patients operated after 1995. There were 22 reoperations including 14 on the right ventricular outflow tract. The non-reoperation rate at 10 years was 80% for simple TGA versus 70% in complex TGA (p= 0.0001). Survivors are asymptomatic with a normal ECG and normal LV function on echocardiography. Five patients have significant pulmonary stenosis and 4 have mild aortic regurgitation. The exercise stress tests performed between the ages of 7 and 10 were all normal. The authors conclude that that modern and reproducible management of TGA is possible in an inter-regional centre with results comparable to those of surgical centres of reference.

[Value of the Norwood-Sano compared with the classical Norwood procedure in hypoplastic left heart syndrome]. / Intérêt de l'intervention de Norwood-Sano par rapport à l'intervention classique de Norwood dans l'hypoplasie du coeur gauche.

Palliative treatment of the hypoplastic left heart syndrome is rarely practiced in France because of the poor prognosis of the first surgical stage of the Norwood procedure. The recent modification proposed by Sano seems to give more promising results. The authors report their experience with the Norwood-Sano procedure compared with the classical Norwood procedure in 13 neonates with hypoplasia of the left heart. From 1999 to 2005, 8 patients underwent the classical Norwood procedure (1999-2001) and 5 had the Sano modification (2002-2005). During the preoperative period, there was 1 case of a very restrictive interatrial septum and 5 patients required mechanical ventilation. The patients were operated at an average age of 8.5 +/- 12 days. The results showed that survival after the first surgical stage was significantly better with the Sano modification (12.5% versus 80%; p= 0.03). All patients who survived the first stage went on to the second stage with a bi-directional right superior cavo-pulmonary derivation at an average of 6.1 +/- 2.4 months. Despite the infundibulotomy of the Sano modification, no arrhythmia or right ventricular dysfunction was observed after an average follow-up of 21.7 +/- 7.6 months. The authors conclude that the Sano modification improved survival of patients with hypoplasia of the left heart after the first palliative surgical procedure. The long-term follow-up of patients operated by this technique should particularly look out for arrhythmias and right ventricular dysfunction.

[Endomyocardial fibrosis: a rare case of restrictive cardiomyopathy in a Caucasian female]. / Fibrose endomyocardique: une cause rare de cardiomyopathie restrictive chez une patiente caucasienne.

The authors report the case of endomyocardial fibrosis diagnosed in a young Caucasian female presenting with progressive congestive cardiac failure. The diagnosis was suspected on the echocardiographic, magnetic resonance imaging and cardiac catheterisation findings in association with the clinical presentation. After a short course of symptomatic medical therapy, the patient underwent the only curative treatment of this pathology, surgical endocardectomy and combined valvular surgery. The confirmation of the diagnosis was obtained a posteriori by histopathological examination of the operative findings which showed appearances of endomyocardial fibrosis similar to those observed in tropical regions. The patient was discharged on the eighth postoperative day, much improved clinically, and follow-up at one year was very satisfactory.

Prosthetic valve endocarditis: who needs surgery? A multicentre study of 104 cases.

OBJECTIVES: To identify the prognostic markers of a bad outcome in a large population of 104 patients with prosthetic valve endocarditis (PVE), and to study the influence of medical versus surgical strategy on outcome in PVE and thus to identify patients for whom surgery may be beneficial. DESIGN: Multicentre study. METHODS AND RESULTS: Among 104 patients, 22 (21%) died in hospital. Factors associated with in-hospital death were severe co-morbidity (6% of survivors v 41% of those who died, p = 0.05), renal failure (28% v 45%, p = 0.05), moderate to severe regurgitation (22% v 54%, p = 0.006), staphylococcal infection (16% v 54%, p = 0.001), severe heart failure (22% v 64%, p = 0.001), and occurrence of any complication (60% v 90%, p = 0.05). By multivariate analysis, severe heart failure (odds ratio 5.5) and Staphylococcus aureus infection (odds ratio 6.1) were the only independent predictors of in-hospital death. Among 82 in-hospital survivors, 21 (26%) died during a 32 month follow up. A Cox proportional hazards model identified early PVE, co-morbidity, severe heart failure, staphylococcus infection, and new prosthetic dehiscence as independent predictors of long term mortality. Mortality was not significantly different between surgical and non-surgical patients (17% v 25%, respectively, not significant). However, both in-hospital and long term mortality were reduced by a surgical approach in high risk subgroups of patients with staphylococcal PVE and complicated PVE. CONCLUSIONS: Firstly, PVE not only carries a high in-hospital mortality risk but also is associated with high long term mortality and needs close follow up after the initial episode. Secondly, congestive heart failure, early PVE, staphylococcal infection, and complicated PVE are associated with a bad outcome. Thirdly, subgroups of patients could be identified for whom surgery is associated with a better outcome: patients with staphylococcal and complicated PVE. Early surgery is strongly recommended for these patients.

[Medico-surgical treatment of occlusion of the left pulmonary artery by extension of ductal tissue (pulmonary coarctation)]. / Traitement médico-chirurgical de l'occlusion de l'artère pulmonaire gauche par extension de tissu ductal (coarctation pulmonaire).

The authors report the results of surgical treatment completed by interventional catheterisation of occlusion of the left pulmonary artery by extension of ductal tissue. Since 2001, 7 patients operated for occlusive coarctation of the left pulmonary artery at an average age of 11 months (3 to 37 months) had a restenosis. The cardiac malformation was pulmonary atresia with ventricular septal defect (N=4), tetralofy of Fallot (N=2) and critical pulmonary valvular stenosis (N=1). Pulmonary artery surgery consisted of resection anastomosis in 4 cases and a plasty in 3 cases. A primary angioplasty was performed 5 to 170 months (median 12 months) later, at an average age and weight of 3.4 years (0.7 to 16.9 years) and 14 Kg (8 to 52 Kg) with implantation of 3 stents. The median diameter increased from 5 mm (1 to 9 mm) to 10 mm (6 to 16 mm). Tc-99m scintigraphy showed an increase in mean left pulmonary perfusion from 9% (6 to 28%) to 28% (18 to 42%). Secondarily, 3 repeat angioplasties were necessary with a total of 6 stents implanted in 7 patients. After an average of 2.9 years (0.8 to 6.3 years) follow-up, the patients were asymptomatic with normal right ventricular pressures and a mean left pulmonary perfusion of 33% (24 to 45%). The authors conclude that the treatment of left pulmonary occlusion by coarctation requires a medico-surgical approach in which angioplasty and stenting complete successfully the surgical revascularisation.

[Results of surgery for coarctation of the aorta in children under one year of age]. / Résultats de la chirurgie de la coarctation aortique chez l'enfant de moins de 1 an.

The aim of this study was to determine the surgical results of repair of coarcta tion of the aorta in children under 1 year of age and to assess the risk of recoarctation. Between 1984 and 2004, 206 children under 1 were operated for coarctation of the aorta. Three groups of patients were identified: Group I (isolated coarctation, N=99), Group II (associated ventricular septal defect, N=63), and Group III (complex congenital heart disease, N=44). The transverse aorta was hypoplastic in 51% of cases. Uni- and multivariate analysis of the risk factors for mortality and recoarctation was performed. An extended resection anastomosis was performed in 206 patients. Reconstruction of the transverse aorta was performed in 32 cases. The hospital mortality was 3.9% (N=8). The presence of a complex intracardiac anomaly was a risk factor for mortality on multivariate analysis (p=0.023). In univariate analysis, a two-step management of patients in Group III was a significant risk factor for mortality (p=0.036). Thirty patients (14.6%) had recoarctation (gradient > 20 mmHg, follow-up 40 +/- 44 months). On multivariate analysis the severity of the immediate postoperative gradient was the only risk factor for recoarctation. The authors conclude that surgery for coarctation of the aorta is associated with excellent results in children under 1 year of age. The prognosis is related to the presence of associated severe cardiac malformations. Survival seems to be better if treatment is carried out in a single stage in this group. The risk of recoarctation is related to the immediate postoperative transisthmic gradient which justifies extensive repair of hypoplastic aortic arches.

[Extracorporeal assistance in paediatric intensive care]. / Assistance extracorporelle en réanimation pédiatrique.

OBJECTIVE: For 3 years we have used extracorporeal assistance in intensive care frequently. This study evaluates our results. METHOD: We studied the patient records for those treated between January 2002 and January 2005. The method used, indications and morbidity/mortality were analysed. RESULTS: We performed 24 circulatory assistance procedures in 20 patients (median age: 5 months), arterio-venous with oxygenation (n=18), veino-venous with oxygenation (n=3) or biventricular (n=3). The indications were post cardiotomy cardio-respiratory failure (Group I; n=20, 16 patients), pure respiratory failure (Group II: n=1), or pre-transplant/recovery (Group III: n=3). Five procedures (4 from group I and 1 from group III) required cardiac massage (no fatalities). The average duration of assistance was 7 +/- 6 days (2 to 20 days). Treatment was successfully discontinued in sixteen patients 80%), one of them thanks to heart transplant. Four (20%) died during assistance. The morbidity essentially consisted of further surgery for haemostasis, multiple transfusions, and infections. Three patients (15%) died later (1 at 17 months after discontinuation) from complications unrelated to the assistance. No neurological sequelae were noted in the survivors. CONCLUSION: These results confirm the usefulness of circulatory assistance when medical treatment has failed, particularly in the post-operative period of paediatric cardiac surgery or while awaiting transplantation.

[Efficacy of angioplasty of native coarctations of the aorta of the big infant and of the adult with systematic endoprosthesis implantation]. / Efficacité de l'angioplastie des coarctations natives de l'aorte du grand enfant et de l'adulte avec implantation systématique d'endoprothèse.

The angioplasty of native coarcatations of the aorta remains a controversial treatment due to recurrences and the potential risk of aneurysm or of descending aorta dissection during catheterization. The interest of a systematic implantation of an endoprothesis is poorly documented. We report our experience in a small series of 3 patients aged from 7, 28 to 52 years at the moment of the angioplasty of their native aortic coarctation. In all the three cases it corresponded to a "membranous" type, localized a the level of the isthmus without hypoplasia of the aortic arch. All presented a refractory hypertension. One patient presented an intermittent claudication related to a low perfusion of lower limbs. The angioplasty was performed with BIB balloon, associated at the same time with the implantation of a Palmaz P308 stent in two cases and Genesis PG2910P in the last patient. The efficacy was immediate in all the 3 cases with stopping antihypertensive drugs at the very day of the procedure. The immediate results were complicated by a bilateral hematoma of the scarpa in a context of excessive anticoagulation in one patient requiring blood tranfusion. After a follow-up of one, 12 and 21 months, all the 3 patients are asymptomatic without any significant residual hypertension. The control scan of the infant confirmed the absence of re-coarctation. In conclusion, the angioplasty followed by systematic implantation of an endoprosthesis is a safe and effective technique for treating simple forms of native coarctations of the aortic isthmus. It can be proposed as a first line treatment for big infants and adults affected by localized types.

[Results of the surgery of the truncus arteriosus: present implications]. / Résultats de la chirurgie du tronc artériel commun: implications actuelles.

We report our results of truncus arteriosus surgical reparation in a period of 10 years. From January 1993 to November 2003, 17 patients were operated with a median age and weight of 66 days and 3.5 kg respectively. According to the Van Praagh classification there were 13 cases of type A1, 2 cases of type A2 and 2 cases of A4. The connection between the right ventricle and the pulmonary artery was performed by a homograft (n = 12), a Contegra tube (n = 1) or a Barbero-Marcial intervention (n = 4). In one case, a plasty of the truncus was performed. Patients were classified in two groups: group A for those operated between 1993 and 1997 (n = 8) and group B for those operated after 1997 (n = 9). Five patients died (29%) in the post-operative period, 4 in the group A (50%) and one in group B (11%). The mean duration of intensive care stay was 12.2 (+ 7.4) days. Statistical analysis did not reveal any difference between both groups, especially concerning post-operative treatment or prognosis. In the multivariate analysis, an age below 30 days was a risk factor of post-operative death (OR = 16.5, 95% CI = 1.09 - 250; p = 0.043). After a mean follow-up of 3.9 (+ 3.5) years, 2 patients required a redo intervention for replacement of the pulmonary artery homograft. All 12 suvivors are asymptomatic without any pulmonary hypertension. In conclusion, the results of surgical reparation of the truncus arteriosus seem to improve with experience. According to recent progresses in surgery and intensive care, the intervention can be scheduled beyond the neonatal period without additive risk and with potentially less consecutive redo interventions.

[Restrictive cardiomyopathy due to myofibrillar myopathy]. / Une cardiomyopathie restrictive révélatrice d'une myopathie myofibrillaire.

UNLABELLED: Early and severe cardiomyopathy may be related to myofibrillar myopathy. CASE REPORT: We report a one-year-old child with early and severe restrictive cardiomyopathy. The diagnosis of myofibrillar myopathy was obtained on skeletal muscle and endomyocardial biopsies. The patient died despite inotropic support and mechanical ventilation. CONCLUSION: Myofibrillar myopathy must be considered when exploring the etiology of a restrictive cardiomyopathy in children. The diagnosis relies on examination of endomyocardial or skeletal muscle biopsy samples.

[Outcome of infants with hypoplastic left heart syndrome diagnosed in utero]. / Devenir des enfants atteints d'une hypoplasie du coeur gauche diagnostiquée in utero.

The authors report the results of prenatal diagnosis of the hypoplastic left heart syndrome since 1998 in the University Hospitals of Marseille and Montpellier. Twenty-four prenatal diagnoses of this condition were made in mothers with a mean age of 29 (18 to 40 years) and after a mean term of 22 (18.5 to 33) weeks of amenorrhea. Seventeen therapeutic abortions were carried out and 7 neonates born after a mean term of 39 (28 to 40) weeks, were admitted to the paediatric intensive care unit. Two patients required ventilatory assistance with one early death. The other patients were stable after surgery. A Norwood (first stage) procedure was carried out in 6 neonates at a mean age of 5 (1 to 6) days. There was only one survivor (17%). Prenatal diagnosis of the hypoplastic left heart syndrome allows cardiac and extracardiac evaluation of foetuses with this condition. Therapeutic abortions may be proposed and was the commonest choice of the parents in this study. On the other hand, despite better management of neonates with this prenatal diagnosis, the poor prognosis of the Norwood first stage procedure is unchanged. A systematic search for a restriction of the foramen ovale on foetal echocardiography could optimise neonatal management of this problem.

[Dextrocardia with situ solitus, ventricular loop, double outlet hypoplastic right ventricle and L-malposition of the great arteries. Description and surgical treatment of a rare and complex cardiopathy]. / Dextrocardie avec situs solitus, coeur croisé, ventricule droit hypoplasique à double issue et L-malposition des gros vaisseaux. Description et traitement chirurgical d'une cardiopathie rare et complexe.

Despite the cardiac surgery improvements allowing the correction of the majority of congenital heart diseases with ventricle-great vessels discontinuity, some abnormalities increase the risk of bi-ventricular reparation. We herein report the case of a patient presenting a rare form of double outlet right ventricle with a ventricular loop, with moderate right ventricle hypoplasia. L-malposition of great vessels and pulmonary artery stenosis, and for whom we opted for a palliative surgical treatment including a systemic-pulmonary anastomosis followed by a upper right bi-directional cavo-pulmonary derivation. The last surgery was followed by recurrent right pleural effusions disappearing after the embolization of the systemic-pulmonary anastomosis by catheterism as it probably obstructed the draining of the cavo-pulmonary anastomosis. The relevance of this clinical case reported is, firstly the description of this ventricle loop resulted from a marked ventricular malposition which is a rare heart disease, and secondly the discussion about the surgical treatment, especially about the choice between palliative and curative surgery. Only comparative studies on long term morbidity and mortality between the bi-ventricular reparation and mono-ventricular palliation will allow the selection of the most appropriate surgical treatment.

[Geographic variations in access to heart transplantation in France]. / Variations géographiques de l'accès à la greffe cardiaque en France.

This study was undertaken to determine whether there were regional variations in the access to the national waiting list for cardiac transplantation and in access to cardiac transplantation itself in France. The incidence of inscription on the waiting list for transplantation was calculated for new candidates living in each region between 1998 and 2000, indicating the level of access to the waiting list. The average interval before transplantation between 1995 and 2000 was calculated by the Kaplan-Meier method. The regional lack of transplant organs was estimated by the ratio of the difference between patients inscribed on the waiting list and those operated, over the number of patients operated. The overall national incidence of inscription of the waiting list for cardiac transplantation was 8 new patients per year per million inhabitants with a range of 1.7 in Corsica to 12.1 in Lorraine. The regional incidence was lower than the national reference in 5 regions in higher in 4 regions. There was a strong attraction of patients to the Ile-de-France, Pays de la Loire and Rhone-Alpes regions. The average waiting time for transplantation in France was 3.7 months and ranged from 1.2 months in Brittany to 15.4 months in Aquitaine (p < 0.001). The degree of regional lack of transplant organs was significantly and positively correlated with the average waiting time for transplantation. The results of this study show that there are regional differences in the incidence of inscription on the waiting list for cardiac transplantation in France and a significant variation in waiting times for cardiac transplantation, and therefore, in access to cardiac transplantation.

Comparison of clinical and echocardiographic characteristics of Streptococcus bovis endocarditis with that caused by other pathogens.

The aim of our study was to compare the clinical, echographic, and prognostic features of Streptococcus bovis (S. bovis) endocarditis with those caused by other streptococci and pathogens in a large sample of patients with definite endocarditis by Duke criteria, using transesophageal echocardiography. Two hundred six patients (149 men, mean age 57 +/- 15 years) with a diagnosis of infective endocarditis formed the study population. All patients underwent multiplane transesophageal echocardiography and blood cultures. Cerebral, thoracoabdominal computed tomographic scan was performed in almost all patients (95%). All patients with S. bovis endocarditis underwent colonoscopy. Incidence of S. bovis endocarditis in our sample was 19%. Patients with S. bovis endocarditis were older than other groups. Multiple valve involvement, native valves, and large vegetations (>10 mm) were more frequent in patients with S. bovis. There was a significantly higher occurrence of embolism in the S. bovis group. Splenic embolism and multiple embolisms were significantly more frequent in patients with S. bovis. Gastrointestinal lesions, anemia, and spondylitis were observed more frequently with S. bovis endocarditis. In addition to the requirement for gastrointestinal examination for S. bovis endocarditis, our study underlines the need for systematic screening for vertebral and splenic localizations, and suggests the use of early surgery to prevent the high risk of embolism in these patients.
