Abstract
AIM OF THE STUDY To obtain a consensus from a panel of experts (GP and cardiologists) on the elements to appear on the correspondence sent by GP at the patient's first consultation with the cardiologist and on the response of the cardiologist. METHOD A list of proposals concerning the content of the exchanges between the GP and the cardiologist was established by a scientific council of three GPs and one cardiologist, based on a review of the literature and their practices. This list was submitted for evaluation to a panel of GP and cardiologists experts using the modified RAND/UCLA Delphi method. RESULTS Twenty nine experts (16 MG and 13 cardiologists) participated in the two evaluation rounds. For the contents of the letter written by the GP, 11 themes have reached consensus: administrative data, reason for consultation, history of the disease, recent constants, current treatments, current or previous pathologies and cardiovascular risk factors, physical activity, psychosocial context, test results, question asked to the cardiologist, cardiologist's perimeter of action. For the contents of the letter of the cardiologist's response, 11 themes were agreed: administrative data, reason for consultation, previous information, clinical examination, ECG, ultrasound, other complementary examinations, answer to the question asked by the GP, dietary treatments, proposed treatments, proposal for follow-up and management. CONCLUSION This study have reached consensus on the elements to appear on the letters exchanged between the GP and the cardiologist.

Abstract
INTRODUCTION Patients with a history of coronary artery bypass and aortic valve disease constitute a high-risk group for conventional redo surgery. The transcatheter aortic valve implantation (TAVI) may be an alternative for high-risk patients. The purpose of this study is to evaluate the impact of TAVI in the treatment of aortic valve disease after previous surgical coronary artery revascularization. PATIENTS AND METHODS This is a single-center retrospective, observational study, including 87 patients undergoing surgery for surgical heart valve replacement or TAVI from January 2007 to December 2013. RESULTS The introduction of transcatheter aortic valve implantation techniques has doubled the number of redo patients treated for aortic valve disease. From 2010 to 2013, the patients treated by conventional surgery diminished by 30%, with improved postoperative outcomes. This study allowed us to notice differences in patient's in terms of operative risk factors. For the same reasons no comparison was possible between 2 subgroup of patients. Hospital mortality was 6.4% for conventional aortic surgery and 20% for transcatheter aortic valve treatment. CONCLUSION Surgery remains the standard treatment for aortic valve disease even in redo patients, but TAVI becomes a very interesting tool as it may represent a tailored approach for our patients.

Abstract
Kawasaki disease is an inflammatory arterial disease of unknown cause usually affecting young children, the principal complication of which is coronary artery aneurysm. Early treatment with immunoglobulins and aspirin prevents this complication. The diagnosis requires expert clinical criteria and, in atypical forms, a more recent decisional diagnostic tree has to be used. The authors report 6 cases of adult Kawasaki disease. As in the other sixty or so cases in the literature, hepatic forms were the commonest (5/6). Only three of the six cases met the classical clinical criteria and the diagnosis was made by the decisional tree or after coronary complications in the oldest subject. The five treated patients progressed favourably after a course of immunoglobulins. Echocardiography detected 100% of children with coronary disease but it was more difficult in adults in whom new non-invasive methods of coronary imaging (fast CT and MRI) and stress testing should complete the investigations. The association of prolonged pyrexia, clinical criteria and a biological inflammatory syndrome should, after exclusion of the differential diagnoses, suggest a diagnosis of Kawasaki disease in the adult as in the child. The possibility of coronary disease, even though extremely rare, should be recognised by the cardiologist and lead to diagnostic and therapeutic managements as aggressive as in children.

Abstract
The Williams-Beuren syndrome is the association of elf-like facies, mental retardation with cardiovascular anomalies, the most common of which is supravalvular aortic stenosis. This lesion may be focal or associated with hypoplasia of the distal aorta. The treatment is surgical and the role of interventional cardiological treatment is poorly defined. The authors report the case of a child with typical Williams-Beuren syndrome. An initial, very localised surgical aortic repair was performed at 3 months of age for a discrete supravalvular aortic stenosis. Two months later, a second operation was required for a new stenosis of the distal anastomosis associated with marked hypoplasia of the aortic arch. The progressive constitution of an isthmic coarctation led to the percutaneous implantation of a stent followed by two balloon dilatations. Only the first two endoluminal procedures successfully reduced the transisthmic pressure gradient. An antihypertensive treatment was given and regular echocardiography allows monitoring of the adaptation of the left ventricle.

Abstract
The authors report the case of a 39 years old woman operated for tetralogy of Fallot at the age of 6. Multiple complications due to postoperative atrioventricular block and a poor surgical result on the pulmonary outflow tract led to several reoperations. Right ventricular dysfunction with pulmonary regurgitation and mitral tricuspid valve disease in a context of endocarditis on the pacing catheter led to double pulmonary and tricuspid valve replacement with mechanical prostheses. The outcome at follow-up at 3 years is good. To the authors' knowledge, this is the first reported case of double mechanical valve replacement of the right heart after complete repair of tetralogy of Fallot.

Abstract
Intrahepatic portosystemic anastomoses are macroscopic communications between the venous portal system and the systemic circulation and located partly in the liver. We report 4 new cases of type II shunts, which illustrate the circumstances of the diagnosis of these exceptional anomalies. For 2 children, the diagnosis was done antenataly by US and spontaneous involution in a few months was observed. In the third case the malformation was evidenced fortuitously at 3 weeks of life, and this 6-year-old child remains completely asymptomatic so far. Then, in the fourth case, a cerebral venous thrombosis was fortuitously and antenatally evidenced in an otherwise uneventful pregnancy and portosystemic shunt was demonstrated postnataly in the extensive work up of the neonate.

Abstract
The authors report the case of a 64 year old woman with typical valvular pulmonary stenosis in whom spontaneous and sudden reopening of the foramen ovale resulted in cyanosis. Transthoracic echocardiography with injection of contrast provides a complete diagnosis: valvular pulmonary stenosis with a mean pressure gradient of 83 mmHg and massive right-to-left interatrial shunt. The malformation was treated by interventional catheterisation in a two-stage procedure: pulmonary valvuloplasty followed by closure of the foramen ovale because of the persistence of a right-to-left interatrial shunt. The functional improvement was followed by the appearance of effort angina. Coronary angiography showed single vessel disease of the left anterior descending artery treated by stenting. The long-term outcome was satisfactory.

Abstract
Ventricular septal defect is the commonest congenital cardiac lesion and represents 30-40% of all congenital heart disease with a prevalence of 1.8 to 6.5 per 1000 births. The aim of this study was to evaluate the outcome of neonates with ventricular septal defects and to deduce from the echocardiographic appearances in the first year of life a relationship between the initial anatomy and the outcome. Between January 2001 and July 2003, 89 children from the Auvergne region were followed up prospectively for an average period of 7.6 months. The study showed that the majority of muscular ventricular septal defects with a diameter of 3 mm and less progress to a reduction in size and spontaneous closure more commonly and at an earlier stage than perimembranous ventricular septal defects.

Abstract
Hunter's disease, a type II mucoplysaccharidosis, a disease of lysosomal overload, may cause cardiovascular disease. This mainly affects the valves of the left heart which are infiltrated, and results in regurgitation rather than stenosis of the aortic and mitral valves. The general context of this disease explains the fact that only one case of mitral valve replacement was found in a review of the literature. The authors report the case of a young patient who was very symptomatic because of mitral and aortic regurgitation and who underwent double valve replacement of the aortic and mitral valves with mechanical prostheses at 18 years of age. The skeletal involvement and respiratory function led to much discussion before surgical referral but the indication was finally retained in view of the patient's practically normal intellectual functions. Seven years later, the patient is asymptomatic from the cardiac point of view and has been included in a protocol of enzyme therapy.

Abstract
Floating thrombus in the aortic arch is a rare and often under-diagnosed source of peripheral arterial embolic events. We report a case of a patient seen with arterial embolic events: ischemia of the left superior limb and transient stroke. The diagnosis was performed with transesophageal echocardiography and computed tomography. The thrombus completely disappeared after 15 days of oral anticoagulant therapy. Although rare, this diagnosis mustn't be overlooked in the search for an etiology of recurrent and disseminated peripheral ischemic events because the detrimental functional risk related to a delayed diagnosis.

Abstract
Congenital aortic stenosis is a common pathology in adults. The valvular lesion, usually secondary to a bicuspid valve, is dominant. Dilatation of the ascending aorta, the result of a jet lesion or structural wall abnormalities, is often observed in association with the valvular stenosis. Subvalvular stenosis is progressive and may only present late, after surgery of another congenital lesion. Supravalvular stenosis is much less common and is usually diagnosed in a dysgenetic context. Echocardiography is usually diagnostic and enables quantification of the stenosis and evaluation of secondary left ventricular changes. Exercise stress testing is decisional in asymptomatic severe stenosis. Percutaneous valvuloplasty is a good palliative procedure. Other surgical techniques comprise valvular commissurotomy, supravalvular valvuloplasty, valvular replacement (autograft, homo- or heterograft or mechanical prostheses). The indications depend on the quantification of the stenosis, symptoms, the results of exercise testing, the valvular lesion secondary to subaortic stenosis and the progression of the aneurysm of the ascending aorta.

Abstract
PATIENTS AND METHODS Between March 1, 1995 and February 29, 1996, a multicentric prospective study was conducted in France in order to analyze the cardiovascular complications in Kawasaki syndrome, and to describe the echocardiographic features and the outcome of coronary lesions. Forty-nine cases of Kawasaki syndrome were observed. RESULTS There were 32 boys and 17 girls (sex ratio: 1:9). The age at diagnosis was under one year in ten cases (20.4%), between one and five years in 27 cases (55.1%) and more than five years in 12 cases (24.5%). The complete diagnostic criteria were present in 42 cases (85.1%). Forty-five children (91.8%) were given intravenous immunoglobulin treatment but only 20 (40.8%) received this treatment within the seven days following the onset of the illness. Cardiovascular complications consisted of: pericardial effusion in 12 cases (24.5%), coronary dilation in seven cases (14.3%), coronary aneurysms of moderate size in seven cases (14.3%,) with hypokinetic left ventricle in two cases. No death was reported. All patients with coronary dilation and four patients with coronary aneurysms had a normal size of coronary arteries at echocardiography within the nine months of the follow-up. Among the three other patients, after a follow-up of two years, one still has a small coronary aneurysm and two have a normal size of coronary arteries. CONCLUSION Despite a delayed administration of immunoglobulin therapy in the majority of patients in this study, outcome of coronary lesions was favorable and severe cardiac complications were rare in the acute phase of the Kawasaki syndrome.

Abstract
The authors report a spontaneous, unusual complication of coarctation of the aorta. An 11 year old child was admitted for investigation of chest pain. Cardiovascular examination revealed typical clinical signs of coarctation of the aorta. Neurological examination found neck stiffness without headache or deficit. The presumptive diagnosis of dissection of the aorta was infirmed by echocardiography and MRI. The latter investigation, with views of the spinal cord, revealed a compressive medullary extradural haematoma. Antihypertensive therapy and corticosteroids with strict bed rest resulted in complete regression of the haematoma and the coarctation was operated 6 months later. Medullary complications of coarctation of the aorta are usually postoperative. Spontaneous complications are exceedingly rare but very serious: medullary compression by the dilated anterior spinal artery or rupture of an aneurysmal collateral vessel. In this case, magnetic resonance imaging led to diagnosis and effective early treatment of this complication before the patient developed a neurological deficit and the coarctation was treated surgically thereafter.

Abstract
Dobutamine stress echocardiography (DSE) and exercise stress echocardiography (ESE) are widely used for diagnosis of coronary artery disease. Each of these methods has limitations: secondary effects of Dobutamine, poor imaging quality, difficulty in attaining the maximal heart rate. The authors evaluated a test associating pedalling exercise at a constant low load (30-60 watts) with Dobutamine infusion (10-20-30-40 j/Kg/min +/- Atropine) (DES + E) in 42 patients referred for suspected coronary artery disease. All patients underwent coronary angiography on Day 1. There was significant coronary disease (> 50% stenosis) in 19 of the 42 patients. Sensitivity, specificity, negative predictive value, positive predictive value and overall diagnosis value were respectively 84, 87, 84, 87 and 86%. In the first 20 patients, the DES + E was compared directly with DES: There was only one undesirable side effect (hypertension) with DES + E compared with 5 with DES alone. The target heart rate was attained with lower doses of Dobutamine with DES + E (32.35 vs 39.42 j/Kg/min, p = 0.05). DES + E therefore seems to be a promising technique which is better tolerated than DES alone with very satisfactory diagnostic performances. However, these results require further confirmation in larger numbers of patients.

Abstract
The diagnosis of acute myocarditis in children is based on histological criteria. Often viral in origin, it results in acute left ventricular dysfunction, the clinical manifestations of which are very variable. The potential severity of the disease is maximal in its initial phase, justifying rapid and intensive treatment. Long-term outcome is relatively good although there is a risk of chronic left ventricular dysfunction. This retrospective study is based on 11 cases of acute myocarditis admitted to the paediatric unit of Clermont-Ferrand University Hospital between February 1989 and March 1999. The initial symptoms were non-specific. Echocardiography was the key diagnostic procedure. Half of the patients had severe cardiac failure requiring admission to the intensive care unit. Four cases presented with a severe complication: two embolic events, one syncopal atrioventricular block and one cardiac arrest. The cardiac treatment was classical (digitalis, diuretics, angiotensin converting enzyme inhibitors, anticoagulants). The aetiology was established in 3 cases (toxoplasmosis, haemolytic and uraemic syndrome, Kawasaki) and a viral cause was suspected in 6 other cases (adenovirus in 3 cases, herpes virus, RSV and enterovirus in 1 case). There were no deaths in the acute phase. The long-term outcome was globally good: complete regression in 8 cases, 1 chronic left ventricular dysfunction and 2 late deaths due to intractable cardiac failure. This short series illustrates the often misleading presentation of acute myocarditis in childhood, the value of systematic investigation in the hope of a specific treatment becoming available in the near future for the often viral aetiology.

Abstract
The objective of permanent pacemaker implantation is to provide against an increased risk of death or to improve quality of life by abolishing symptoms. In both cases, certain indications for pacing have clearly demonstrated to be strongly beneficial in well selected patients, but other are still controversial, due to the lack of convincing and converging published data, or to the absence of general consensus among specialists, or because selection criteria for pacing have been poorly defined. We try to clarify when to pace or not to pace in such conditions as first degree AV block, type I second degree AV block, intracardiac conduction defects, including those occurring at the acute stage of myocardial infarct or after cardiac surgery, sick sinus syndrome in cardiac transplant recipients, carotid sinus syndrome, vasovagal syncope, and unexplained syncopes.

Abstract
In this prospective study we evaluated the efficacy of a battery of noninvasive tests including clinical evaluation (CE), exercise testing (ET), and dobutamine stress echocardiography (DSE) for assessment of cardiac risk in 90 patients indicated for aortic reconstruction. As the gold-standard reference technique, coronary arteriography was performed in each patient after noninvasive evaluation. The sensitivity of CE was low (61%). ET proved to be more sensitive (71.4%) and highly specific (95.8%) but feasibility (77%) and diagnostic accuracy (42%) were low. DSE demonstrated acceptable sensitivity (78%) and specificity (75.5%) with high feasibility (94.5%) and diagnostic accuracy (100%). None of the four patients with false negative ET results and only one of seven with false-negative DSE required coronary bypass. On the basis of these findings we conclude that a combination of CE and ET with DES, if necessary, can reliably assess cardiac risk before aortic reconstruction. Noninvasive assessment is a reliable alternative to routine coronary arteriography.

Abstract
Although coronary stenting reduces the incidence of post-angioplasty restenosis, it remains a problem. The influence of lipoproteins on the development of atherosclerosis has been demonstrated but their role in restenosis is controversial. Contradictory results have been published on the subject of the influence of the APO E genotype. In an initial study, the authors showed a closer correlation between Lp (a) and coronary artery disease in women than in men. A sub-group of women who underwent angioplasty and whose lipid profile had been well established, was analysed with respect to APO E alleles. The 59 patients who underwent angioplasty included 35 single, 20 twin and 4 triple vessel diseases. Control coronary angiography was performed in 40 of these women. A telephonic interview was carried out between 12 and 22 months after dilatation on the whole population. The apolipoproteins A1, B, Lp (a) and Lp A1 were measured by immunological, turbidimetric or electroimmunological techniques. The APO E genotyping was performed with the Inno-Lipa kit. The results showed 18 angiographic restenoses (Group A), 20 coronary artery disease without restenosis (Group B), 41 without angiographic (20) or clinical (21) restenosis (Group C). In Group A, the Lp (a) was well above the threshold value of 0.30 g/l. The e4 allele was associated with the highest values of total and LDL cholesterol fractions. There was no significant difference between the APO E genotype of the different groups or with respect to the severity of lesions. The authors conclude that if the e4 is more commonly associated with high LDL-cholesterol and Lp (a), its role in the process of restenosis remains unproven. A greater number of patients is required and further studies are desirable to determine the inflammatory and/or immunological mechanisms through which APO E could influence restenosis.

Abstract
Left triatrial heart is defined as division of the left atrium into two chambers, proximal and distal, by a variably perforated membrane. The data of appearance of symptoms, often in early childhood, is related to the degree of obstruction and the presence or not of an inter-atrial shunt. Widescale usage of echocardiography, the investigation of choice for this diagnosis, has led to the detection of this abnormality in older patients, sometimes asymptomatic, without pulmonary hypertension. Three adults were referred for transthoracic and transoesophageal echocardiography to investigate systemic embolic disease (2 cerebral, 1 mesenteric). Two other adults underwent the same investigations for diagnosis of the aetiology of atrial fibrillation with mitral regurgitation. Two cases were asymptomatic children, one with a clinically benign murmur and the other with ventricular extrasystoles with no malignant features. In these seven cases, transthoracic (n = 5) and/or transoesophageal (n = 7) echocardiography demonstrated a left atrial membrane corresponding to the classical description of cor triatrium. The Doppler study showed no obstruction in 6 cases and minimal obstruction in 1 case. In our series, as in similar cases reported in the literature, the diagnosis of a left atrial membrane did not lead to surgery. Although we do not know the long-term outcome of this abnormality in asymptomatic children, the observations of complications in the adult suggest a potential of evolution which poses the question of optimal management.

Abstract
BACKGROUND Experimental studies suggest that the antiproliferative effect of heparin after arterial injury is maximized by pretreatment. No previous studies of restenosis have used a pretreatment strategy. We designed this study to determine whether treatment with nadroparin, a low-molecular-weight heparin, started 3 days before the procedure and continued for 3 months, affected angiographic restenosis or clinical outcome after coronary angioplasty. METHODS AND RESULTS In a prospective multicenter, double-blind, randomized trial, elective coronary angioplasty was performed on 354 patients who were treated with daily subcutaneous nadroparin (0.6 mL of 10,250 anti-Xa IU/mL) or placebo injections started 3 days before angioplasty and continued for 3 months. Angiography was performed just before and immediately after angioplasty and at follow-up. The primary study end point was angiographic restenosis, assessed by quantitative coronary angiography 3 months after balloon angioplasty. Clinical follow-up was continued up to 6 months. Clinical and procedural variables and the occurrence of periprocedural complications did not differ between groups. At angiographic follow-up, the mean minimal lumen diameter and the mean residual stenosis in the nadroparin group (1.37+/-0.66 mm, 51.9+/-21.0%) did not differ from the corresponding values in the control group (1.48+/-0.59 mm, 48.8+/-18.9%). Combined major cardiac-related clinical events (death, myocardial infarction, target lesion revascularization) did not differ between groups (30.3% versus 29.6%). CONCLUSIONS Pretreatment with the low-molecular-weight heparin nadroparin continued for 3 months after balloon angioplasty had no beneficial effect on angiographic restenosis or on adverse clinical outcomes.

Abstract
A 13-year-old boy with tetralogy of Fallot and pulmonary atresia after a Waterston and Blalock-Taussig shunt underwent successful repair using a cryopreserved pulmonary homograft as a valved extracardiac conduit. Aortic transection gave a good operative field for pulmonary angioplasty and closure of the Waterston anastomosis. The cryopreserved pulmonary homograft provided excellent handling characteristics. The postoperative course was good, and postoperative echocardiography showed good function of the valved conduit.

Abstract
The detection of coronary artery disease is essential before abdominal aortic surgery. In view of the limitations of the usual methods of investigation, dobutamine stress echocardiography was assessed in this indication. Eighty-five patients with an aortic abdominal aneurysm or obstructive arterial disease underwent dobutamine stress echocardiography followed by coronary angiography. Depending on the results, vascular surgery was performed directly, after myocardial revascularisation or not at all. Significant coronary lesions (stenosis > or = 50%) were found in 32 of the 85 patients (38%). Dobutamine stress echocardiography had a sensitivity of 78% and a specificity of 75%, and positive and negative predictive values of 66 and 85% respectively. The relative risk of coronary disease was 4.4. In this series, 15 patients had severe coronary lesions: 2 were turned down for surgery and 13 underwent myocardial revascularisation; 14 of them (93%) had a positive stress echo. The only 2 non-fatal cardiac complications of peripheral surgery (3%) occurred after a positive dobutamine stress echo. This study confirms both the necessity of preoperative assessment of coronary risk and the efficacy of dobutamine stress echocardiography in this indication. Dobutamine stress echocardiography is reliable, non-invasive, economical and a real alternative to isotopic methods. Its good predictive value justifies using coronary angiography only for patients with a positive result.

Abstract
The authors present a novel method to estimate absolute blood flow velocity in coronary arteries from biplane angiograms. Spatial and temporal velocity variations are derived giving simultaneously a direct geometric and an indirect functional index of stenosis severity, stenosis ratio and coronary flow reserve. No prior assumption concerning stenosis geometry is made. Deformable models are used to track a coronary artery segment dynamically in three dimensions. A densitometric map is obtained by summing densities across sections at every position along the previously calculated path and at every time of the cardiac cycle. An advection relationship between density and velocity is observed. The spatiotemporal velocity map is a solution of a nonlinear least-squares scheme. A simulation protocol based on simple geometric conformations and blood flow properties is used to assess numerical stability and immunity towards noise. Predicted results for temporal velocity variations are compared with the intracoronary Doppler recordings to test the model assumptions for basal state and hyperaemia examinations of the same patient. The stenosis ratio was accurate to within 3% for a simulated additive Gaussian noise with a standard deviation of 0.14. The limits of agreement between angiographic and Doppler velocities were -11.4 and 11.8 cm s-1 for a peak value of 23 cm s-1 (basal state) and -16.8 and 13.5 cm s-1 for a peak value of 52 cm s-1 (hyperaemia), corresponding to 18 and 3.5% errors on the average peak values and a 16% error on the coronary flow reserve. To summarize, the advection model derivation and its solution are presented. Simulated and experimental results corroborate the validity of the numerical schemes and support clinical applicability.

Abstract
General anaesthesia for cardiac catheterisation of children is a real challenge for anaesthetists. The recent commercialisation of sevoflurane, a new halogenated anaesthetic agent allowing induction by inhalation with an extremely rapid loss of consciousness and recovery with minimal cardiovascular effects, incited the authors to evaluate its use in this indication. Forty children aged 4 months to 10 years undergoing cardiac catheterisation were anaesthetised with a standardised protocol with sevoflurane. An anaesthetic state was obtained in 34 +/- 8 seconds with excellent tolerance, few and transient secondary effects. Changes in respiratory and haemodynamic status during catheterisation were only significant in 5 children with associated pulmonary disease and who developed desaturation requiring oxygen therapy. The recovery times were 6.3 +/- 2.1 minutes for ablation of the laryngeal mask, 7.1 +/- 3.5 minutes to the first cry and 8.4 +/- 3.8 minutes to opening of the eyes. All children were fit for discharge from the post-catheterisation observation ward after an average of 12.5 +/- 4.3 minutes. The most distressing secondary effect on recovery was headache, experienced by 4 children. Sevoflurane would seem to be particularly useful for general anaesthesia for diagnostic or interventional cardiac catheterisation of children.

Abstract
BACKGROUND Nitric oxide (NO) donors, in addition to their vasodilator effect, decrease platelet aggregation and inhibit vascular smooth muscle cell proliferation. These actions could have beneficial effects on restenosis after coronary balloon angioplasty. METHODS AND RESULTS In a prospective multicenter, randomized trial, 700 stable coronary patients scheduled for angioplasty received direct NO donors (infusion of linsidomine followed by oral molsidomine) or oral diltiazem. Treatment was started before angioplasty and continued until 12 to 24 hours before follow-up angiography at 6 months. The primary study end point was minimal lumen diameter, assessed by quantitative coronary angiography, 6 months after balloon angioplasty. Clinical variables were well matched in both groups. However, despite intracoronary administration of isosorbide dinitrate, the reference diameter in the NO donor group was significantly greater than in the diltiazem group on the preangioplasty, postangioplasty, and follow-up angiograms. Pretreatment with an NO donor was associated with a modest improvement in the immediate angiographic result compared with pretreatment with diltiazem (minimum luminal diameter, 1.94 versus 1.81 mm; P = .001); this improvement was maintained at the 6-month angiographic follow-up (minimal lumen diameter, 1.54 versus 1.38 mm; P = .007). The extent of late luminal narrowing did not differ significantly between groups (loss index in the NO donor and diltiazam groups, 0.35 +/- 0.78 and 0.46 +/- 0.74, respectively; P = .103). Restenosis, defined as a binary variable (> or = 50% stenosis), occurred less often in the NO donor group (38.0% versus 46.5%; P = .026). Combined major clinical events (death, nonfatal myocardial infarction, and coronary revascularization) were similar in the two groups (32.2% versus 32.4%). CONCLUSIONS Treatment with linsidomine and molsidomine was associated with a modest improvement in the long-term angiographic result after angioplasty but had no effect on clinical outcome. The improved angiographic result related predominantly to a better immediate procedural result, because late luminal loss did not differ significantly between groups.

Abstract
OBJECTIVES Identify factors predicting favorable outcome after medical management of valve ring abscesses in order to propose a surveillance schedule for conservative treatment. METHODS A multicentric study conducted from July 1989 to February 1996 included 28 patients (mean age 64 +/- 16 years, range 26-83) hospitalized for active endocarditis and valve ring abscesses diagnosed at transthoracic or transesophageal echography. Conservative medical therapy was given because of a decision of the medico-surgical team (n = 9), high surgical risk (n = 12), or patient refusal of surgery (n = 7). Outcome was favourable in 18 patients (Group I) and unfavorable in 10 (Group II) due to death (n = 9) or subsequent surgery (n = 1). Univariate and multivariate analysis were used to determine differences between the groups in terms of clinical and laboratory data. RESULTS Mean follow-up in Group I was 33 +/- 18 months and 15 +/- 10 months in Group II. Univariate analysis showed significant differences between Group I and II respectively for age (59 +/- 18 yr vs 72 +/- 10, p = 0.04), delay to apyrexia after antibiotics (4.3 +/- 2.8 vs 8.3 +/- 2.4 days, p < 0.0008), heart failure (5% vs 70%, p = 0.003), grade III or IV valvular regurgitation (5% vs 60%, p < 0.04), and mean surface area of the abscess (1.5 +/- 1.2 vs 5.4 +/- 6.4 cm2, p < 0.03). Independent factors at multivariate analysis were by decreasing order: lack of heart failure at admission, delay to apyrexia, abscess surface area, and age. Outcome was favorable (mean follow-up 33 +/- 10 months) in all patients with an abscess surface area < 1.5 cm2, no signs of heart failure, no grade III or IV valvular regurgitation, apyrexia after less than 8 days on antibiotics and no staphylococcus positive blood culture. CONCLUSION Medical management of valve ring abscesses may be indicated in selected patients in care units with rigorous surveillance facilities. Further studies are needed to precisely identify surveillance and treatment criteria.

Abstract
The aim of this study was to determine the diagnostic efficiency of transesophageal echocardiography (TEE) in isthmic aortic ruptures and to describe the echocardiographic Doppler anomalies. TEE was performed prospectively for 18 months in 33 patients with serious polytraumas requiring intensive care. The average age was 40.75 years (range, 17 to 78 years). Single or biplanar TEE was used. In three patients with aortic transection, echocardiography showed an intimal flap thicker than that of dissections. The flaps were torn and retracted on the free edge. It was difficult to distinguish the periaortic hematoma. Doppler imaging showed turbulent flows in several places around the aorta. These flows were especially visible at the beginning of the intimal flap. They were visible on M-mode color imaging during systole and diastole. During diastole, a large color flow was observed in the middle of the aortic lumen. It was turbulent in some places and mimicked the systolic filling of the aorta. These flows create the characteristic "to and fro sign" spectrum of Doppler imaging, usually seen in peripheral false arterial aneurysms. TEE findings were confirmed in two cases by surgery and in one case by aortography. TEE seems to be an effective means of detecting isthmic rupture, with the diagnosis resting on the data obtained from echocardiography and Doppler imaging. A suspected isthmic disruption should be assessed by an emergency TEE and aortography used only for uncertain or complex cases.

Abstract
A multicentre study was undertaken to determine the diagnostic value of transoesophageal echocardiography (TOE) in tumours of the heart and pericardium. Forty-five cases were recensed: 24 myxomas, 1 fibroma, 1 hydatid cyst, 2 lymphomas, 3 sarcomas, 1 pleuropericardial cyst, 1 branchogenic cyst and 12 cardiac metastases. The diagnosis was made in all 45 cases by TOE but only in 35 cases by conventional transthoracic echocardiography which failed to recognise 2 myxomas, 1 hydatid cyst, 1 sarcoma, 2 paracardiac cysts and 4 cardiac metastases. The site of the tumour was identified 45 times by TOE compared with only 12 times by transthoracic echocardiography. However, the anatomical investigation of mediastinal tumours requires complementary computerised tomography. Moreover, TOE, like all other imaging techniques, is unable to predict the benign or malignant nature of the tumour, 1 leiomyosarcoma having been confused with a myxoma.

Abstract
The authors discuss echocardiographic diagnosis and endovascular treatment of two different anatomical types of pulmonary arteriovenous fistula. Transoesophageal echocardiography in a cyanotic 3 year old boy revealed a direct right pulmonary artery left atrial fistula, treated by surgical ligation of the anomalous feeding artery. A cerebral abscess in a 22 year old man with hereditary haemorrhagic telangiectasia revealed pulmonary and cerebral arteriovenous malformations, which were both treated successfully by embolization. The value of echography is the demonstration of the right to left shunt at pulmonary level and, in some cases, the direct visualization of the arteriovenous malformation. Embolization should be considered as the therapeutic method of choice in all pulmonary arteriovenous fistula, except for direct pulmonary artery left atrial fistula.

Abstract
To investigate myocardial manifestations in progressive systemic sclerosis, we studied three patients with transthoracic echocardiography, cardiac catheterization with coronary angiography, thallium scans with dipyridamol completed by thoracic cold exposure and endomyocardial biopsy with immunohistology. Two patients were symptomatic. In the three cases, abnormalities of myocardial perfusion were detected without coronary stenosis. Two patients had myocardial fibrosis with a coronary spasm in one case. The immunohistological study always showed an unusual expression of HLA class II antigen on cardiac fibroblasts.

Abstract
The authors report the results of a multicenter study which recensed 59 cases (46 men, 13 women, average age 59.8 +/- 14 years) of valve ring abscesses defined by echocardiographic criteria alone (20 cases) or by echocardiographic and/or operative criteria (39 cases). The site of abscess was aortic (53 cases), mitral (5 cases) and tricuspid (1 case). The abscess complicated a prosthetic valve in 34 cases, occurred with a non-pathological valve in 11 cases or a pathological valve in 14 cases. Taking the 39 operated patients as a reference, the diagnostic sensitivity of transthoracic echocardiography was 25% and that of transoesophageal echocardiography: 88%. Bacterial vegetations were diagnosed with a sensitivity of 55% for transthoracic and 88% for transoesophageal echocardiography. The mediocre results of transthoracic echocardiography make transoesophageal echocardiography mandatory when there is a clinical suspicion of abscess: transoesophageal echocardiography should be systematic in prosthetic valve endocarditis and widely employed in native aortic valve endocarditis. The clinical outcome of these cases was: 39 cases were operated: global mortality of 23%, and 18 cases were treated medically, surgery having been declined for various reasons: old age (2 patients), operative risk (1 patient), patient refusal (4 patients), general condition considered to be too good to justify surgery (11 cases, including 6 sterilised abscesses diagnosed some time after the acute infectious phase). The outcome of these 18 patients, who form the biggest non-operated series of valve ring abscesses to date, was studied in detail: 4 died (18% mortality), 1 was operated secondarily for progressive valve dehiscence and 13 had a favourable outcome with an average follow-up period of 2 years.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A 19-day-old child suffering from cyanosis due to tetralogy of Fallot was palliated by using his right retroesophageal subclavian artery. It was anastomosed side-to-side onto the ascending aorta and end-to-side onto the right pulmonary artery. The palliation obtained with this systemic-pulmonary shunt was satisfying. The right brachial vascular flow was normal.

Abstract
Evaluation of hypertension, in a 30 years old man, revealed an interruption of a left aortic arch beyond the origin of the left subclavian artery, associated with a right descending thoracic artery. Surgical restoration of the continuity between the ascending aorta and the low descending aorta was successfully achieved by interposition of a graft. Survival in adulthood without bronchial compression, is explained by the absence of ventricular septal defect and patent ductus arteriosus.

Abstract
BACKGROUND Tumors involving the inferior vena cava and cardiac cavities are rare in nephroblastoma. When they do occur, the standard treatment is primary surgery; but this is often technically difficult. CASE REPORT A 3 year-7-month-old girl was admitted because of an abdominal mass and signs of heart failure. Ultrasonography showed that this mass involved the right renal vein and the inferior vena cava including the right atrium. A CT scan showed no metastases. Echocardiography showed that the mass occupied two thirds of the right atrium and had blocked the tricuspid valve. The patient was given heparin (2 mg/kg/day), vincristine (1.5 mg/m2 on day 1) and actinomycin D (15 micrograms/kg on day 1 to 3). The heart failure disappeared and the abdominal mass decreased in volume. This improvement was confirmed by successive ultrasonographies. Chemotherapy was then completed and the patient was operated on six weeks later: right nephrectomy and removal of the cavoatrial tumoral thrombus. Pathological examination confirmed the nephroblastoma and the patient was given radiotherapy and chemotherapy for 28 weeks. She was also given aspirin for 17 weeks. Pulmonary metastases were detected 1 year after onset and were treated by a combination of surgery and chemotherapy. The patient is well 20 months after the onset of the disease. CONCLUSION Preoperative chemotherapy seems to be effective in nephroblastoma extending to cardiac cavities; it allows subsequent surgery and facilitates postoperative radiotherapy.

Abstract
A hundred and eighty three patients with a primary myocardial infarction less than 4 hours old were included in a double blind trial versus placebo comparing an isolated plasminogen streptokinase activator complex (APSAC: 30 mu in 5 mn) and tissue type plasminogen activator (rt PA: 10 mg bolus followed by 90 mg in 130 mn). Clinical evolution, side effects, patency of the artery responsible for infarction, left ventricular contractile function (contrast angiography on the 7th day and angioscintigraphy on the 21st day) and infarct size were studied. The two groups were comparable in age (54 +/- 11 years), delay in randomisation (170 +/- 50 mn), infarct site and severity of cardiac failure. There was no significant difference in hospital mortality (7 in the rt PA group and 5 in the APSAC group) or in adverse effects (haemorrhage: rt PA: 9 patients, APSAC: 11 patients). The patency was 72% in the APSAC and 76% in the rt PA group. Left ventricular function and infarct size were comparable in the two groups: angiographic EF (0.50 +/- 0.1 in the APSAC and 0.52 +/- 0.1 in the rt PA group: NS); asynergic score (11.3 +/- 1.7 in the APSAC and 10.5 +/- 1.8 in the rt PA group: NS); infarct size (10.9 +/- 8.0 in the APSAC and 9.4 +/- 7.2 in the rt PA group: NS). This trial shows that these two thrombolytic agents have the same efficacy. The authors recommend adaptation of the dosage of rt PA to body weight.

Abstract
BACKGROUND Fetal tachycardia can be a cause of in utero death. Its detection is not always easy and its treatment is still controversial. CASE REPORT Paroxysms of supraventricular tachycardia were detected on echocardiography at the 25th week of a second pregnancy. The mother was given sotalol, but the supraventricular tachycardia became permanent. At the 27th week of gestation, sotalol was stopped and the mother was given digoxin and the foetus received 2 injections of digoxin, 10 micrograms/kg, via the umbilical cord. As this treatment was only partially effective, the mother was also given amiodarone 800 mg/day at week 28, then the dose was reduced to 400 mg/day. However, at the 31st week, the mother showed signs of digoxin intolerance, and it was replaced by sotalol. Fetal blood tests at week 34 showed a high placental transfer of digoxin and sotalol and a low fetal level of amiodarone. The newborn, a girl, was born at the 36th week having a sinus rhythm. She developed signs of hypothyroidism (T4: 4 micrograms/ml; TSH:325 microliters U/ml at 5 days of life). CONCLUSION The placental transfers of sotalol, digoxin and amiodarone are in the range of values known to be effective. The amiodarone responsible for hypothyroidism was given to the mother because she was intolerant to digoxin. Its use must be limited to arrhythmias that are resistant to other drugs or complicated by hydrops fetalis. When used, amiodarone should not be given for more than 6 weeks, and at the lowest possible dose.

Abstract
Since its introduction in cardiovascular therapeutics, thrombolysis has established itself as an effective procedure of coronary reperfusion during the acute phase of myocardial infarction. Large scale clinical trials have demonstrated a clear cut reduction in mortality providing that the treatment is administered sufficiently early after the onset of symptoms. This reduced mortality is probably related to the limitation of infarct size and the conservation of ventricular function even though this relationship is not always analysed. Studies of infarct size and left ventricular function are difficult to perform and this is reflected in the number of different methods proposed. Apart from coronary reperfusion and its timing, other factors influence the definite size of the infarct, such as the development of a collateral circulation, the existence of cellular reperfusion lesions and the occurrence of reocclusion. The infarct size may be assessed by a number of methods, some simple (enzymes, electrocardiogram) but relatively inaccurate, others more promising but difficult to perform and more costly. Thallium 201 scintigraphy seems to be the best available method and our experience is based on these results. The reference method for the evaluation of left ventricular function is angiography but angioscintigraphy also provides information on global and regional function, the regional study being particularly valuable in the analysis of thrombolytic drug efficacy. A review of the literature shows that thrombolysis is associated with a reduction in infarct size compared with conventional therapy and with conservation of left ventricular function whichever thrombolytic agent is used.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This study was based on the follow-up of 55 patients with tetralogy of Fallot and operated for branch pulmonary artery stenosis. Twenty two patients were followed up clinically (Group I): 91% of the patients were asymptomatic at the end of the first operative year. Thirty three patients (Group II) underwent control catheter studies after an average of 2.5 years after complete repair: only 70% of these were asymptomatic at 1 year; 8 were reoperated after an average of 3.6 years. The surgical result could only be evaluated by control catheter studies. The results were therefore based on the data obtained from Group II: this selection resulted in a pessimistic bias as the outcome in the two groups was significantly different. The stenoses were congenital and/or iatrogenic. They were located on the left branch (55%), the right branch (9%), the bifurcation (24%), separately on the two branches (12%). The diversity of the operative techniques and materials used reflects the difficulty of this surgery. The cumulative results were good in 33% of cases, average in 28% and poor in 39%. The results were better in isolated branch stenosis than in stenosis of the bifurcation, though not statistically significant. The results were related to age, body weight, the type, the site, the length, the association of stenoses and the material used. Significant predictive factors for a good result were: Gore-Tex (p less than 0.05) and pericardial pedicle (p less than 0.005). The average follow-up of patients with the latter type of patch was only 2 years. These results require confirmation by studies of larger numbers of patients followed up for a longer period.

Abstract
Defect size on myocardial tomograms was measured in 30 patients who underwent 2 separate studies, 1 with thallium-201 (TI-201), the other with technetium-99m-methoxyisobutyl isonitrile (MIBI). A group of 15 patients with myocardial infarction was studied at rest and received both tracers on the same day. The other 15 patients had documented coronary artery disease. They were were given injections of TI-201 at peak exercise and underwent imaging immediately after exercise and again 4 hours later. They then received a dose of MIBI for imaging at rest. A week later they underwent a second exercise test with the same work load and received a second dose of MIBI. Defect size on single-photon emission computed tomographic images was measured and repeated twice. Results were expressed in percentage of the volume of the whole myocardium. Reproducibility of the defect size measurement was high for TI-201 (r = 0.978; SEE = 1.59) as well as for MIBI (r = 0.981; SEE = 0.80). In patients with coronary artery disease the mean size of the defects was significantly larger with TI-201 than with MIBI at exercise (6.7 +/- 5.2 vs 4.6 +/- 5.2%, respectively, p less than 0.05) and at redistribution (5.1 +/- 4.4 vs 2.8 +/- 3.2%, respectively, p less than 0.05), where no difference was seen in patients with myocardial infarction studied only at rest (11.2 +/- 10.4 vs 12.0 +/- 11.5%, respectively, p = not significant). Smaller MIBI defect sizes, when compared with TI-201, in the exercise and redistribution studies were not due to technical artefacts since there was no difference when they were compared at rest.

Abstract
Two cases of angina pectoris, induced by methylergometrine (Methergin) and by an association of ergotamine tartrate (Gynergene) and methysergide (Desernil) respectively, are reported. In both patients, angiography revealed spontaneous spasm in a coronary system free from any significant atheromatous stenosis. In the second case, a test administration of i.v. Methergin, administered during calcium-channel antagonist treatment a few days after the "guilty" drugs had been stopped was found to be negative. The outcome was favorable in both cases: the angina disappeared and the base-line and exercise ECG returned to normal. The hypothesis of coronary spasm induced by the treatment was adopted in both cases. In this context, the major iatrogenic etiologies of vasospastic angina are recalled, together with the prophylactic and therapeutic measures they call for.

Abstract
In recent acute myocardial infarction, early reperfusion of the infarct-related artery by intracoronary or intravenous thrombolytic therapy induces a significant limitation of infarct size, provided reperfusion occurs within a time frame that myocardial salvage can still be expected. Limitation of infarct size reduces scar tissue formation, aneurysm formation, infarct zone expansion, left ventricular volume enlargement, and eventually results in higher left ventricular ejection fraction. Infarct size limitation and left ventricular function preservation occur with all thrombolytic agents currently in clinical use: streptokinase, alteplase and, more recently, anistreplase. When anistreplase is compared with conventional heparin therapy, a 31% reduction in infarct size is found (estimated from single photon emission computed tomography, or SPECT). This translates into a significant preservation of left ventricular ejection fraction as observed in anistreplase-treated patients compared with heparin-treated patients (0.53 +/- 0.13 vs 0.47 +/- 0.12, p less than 0.002). In comparative trials of 2 thrombolytic agents, anistreplase was demonstrated to be as efficient as alteplase on left ventricular ejection fraction preservation and infarct size limitation.

Abstract
BACKGROUND Recombinant tissue-type plasminogen activator (rt-PA or alteplase) and anisoylated plasminogen streptokinase activator complex (APSAC or anistreplase) have been demonstrated to limit infarct size significantly and to preserve left ventricular function when injected soon after acute myocardial infarction. However, as yet, the efficacy and safety of these two thrombolytic agents have not been directly compared in one trial; this was the aim of this study. METHODS AND RESULTS One hundred eighty-three patients suffering from a first acute myocardial infarction were randomly allocated to either APSAC (30 units over 5 minutes) or single-chain rt-PA (100 mg over a 3-hour period) within 4 hours of the onset of symptoms. Global and regional left ventricular function were assessed from contrast angiography an average of 5.3 +/- 2.3 days after initial therapy. Radionuclide angiography and thallium-201 single-photon emission computerized tomography were performed before hospital discharge. Infarct size was assessed by single-photon emission computerized tomography and expressed in percentage of the total myocardial volume. Ninety patients received APSAC and 93 received rt-PA within a mean period of 172 +/- 52 minutes after the onset of symptoms. The two groups were similar in age, location of the acute myocardial infarction, Killip class, and time of randomization. The patency rate of the infarct-related artery was 72% in the APSAC group and 76% in the rt-PA group (NS). Initial and predischarge left ventricular ejection fraction as well as infarct size were similar in both therapeutic groups (0.50 +/- 0.14 versus 0.52 +/- 0.12 for initial and 0.48 +/- 0.10 versus 0.47 +/- 0.10 for predischarge ejection fraction, 11 +/- 7% versus 9 +/- 7% for infarct size, respectively, for APSAC- and rt-PA-treated patients). Bleeding complications requiring blood transfusion occurred in one APSAC patient and in two rt-PA patients. One patient in the rt-PA group died of a massive intracranial hemorrhage. At the end of the 3-week follow-up period, five APSAC patients (5.5%) and seven rt-PA patients (7.5%) had died. CONCLUSIONS The early infusion of APSAC or rt-PA in acute myocardial infarction produced a similar patency rate, limitation of infarct size, and preservation of left ventricular systolic function with an equivalent rate of bleeding complications.

Abstract
The distributions of 201Tl and 99Tcm-MIBI on stress images were quantitatively measured in a series of 15 patients presenting with documented coronary artery disease. Following two sequential, one-week apart, peak-exercise injections of either 74 MBq of 201Tl or 370 MBq of 99Tcm-MIBI, tomographic views of the myocardium were reconstructed and two thick, central short-axis sections were divided into nine sectors. A sector was considered as showing a defect if its relative activity was lower than 30, 40, 50 or 60% of the highest level of activity in the 18 sectors. Results demonstrate that there were more defects with 201Tl than with 99Tcm-MIBI. However, the difference disappeared if the inferior wall was not included. These results suggest that depth attenuation could be, at least partly, responsible for the higher rate of positive results observed in single photon emission computed tomography with 201Tl than with 99Tcm-MIBI.
