Abstract
Macular edema is the main cause of decreased visual acuity in uveitis and determines the visual prognosis. We retrospectively analyzed the tolerability and efficacy of the dexamethasone intravitreal implant in the management of uveitis. Twenty-five patients with uveitic cystoid macular edema were all treated with the Ozurdex(®) dexamethasone intravitreal implant from January 2012 to August 2014. The main outcome measures were visual acuity recovery, changes in macular thickness and resolution of the vitritis. Thirty-two eyes of 25 patients received 52 injections of Ozurdex(®). Both complete regression of the macular edema and resolution of the vitritis occurred in 100 % patients. Visual acuity improved in 62 % of patients: the mean reduction in macular thickness was 252 (±171μm); the mean time between injections was 6.7 (±3.8) months. Secondary ocular hypertension was seen in 33 % of patients. No patient required secondary surgery although a selective laser trabeculoplasty was required for one patient. The dexamethasone intravitreal implant Ozurdex(®) resulted in continuous and complete regression of uveitic cystoid macular edema. It allows evaluation of the potential visual recovery of treated eyes. The tolerability and duration of action provide a rationale for considering Ozurdex(®) as a first-line therapy for uveitis which remains uncontrolled despite optimal systemic treatment.

Abstract
Atherosclerotic plaques of the thoracic aorta are a well-recognized source of systemic embolism, especially cerebral embolism, in patients 60 years of age or older. The most helpful and readily available imaging technique to detect aortic plaques is transesophageal echocardiogram. Aortic plaques>4mm in thickness are the more likely to cause peripheral embolism. Moreover, plaque morphology is important to consider, since ulcerated plaques and plaques with mobile intra-aortic components ("debris") as well as hypoechoic and noncalcified plaques are at the higher risk of embolism. In addition to these common atherosclerotic lesions, rare cases of mobile thromboses of the aortic arch without aortic debris have been described in younger patients. Finally, a particular situation is that of cholesterol embolism following invasive intra-aortic maneuvers on atherosclerotic aortas. While the diagnosis of these lesions is well established, their management and treatment remain controversial.

Abstract
The aim of the present study was to compare the epidemiological and clinical characteristics of Streptococcus bovis endocarditis with those of endocarditis caused by oral streptococci, using data obtained from a large international database of uniformly defined cases of infective endocarditis. S. bovis, a well-known cause of infective endocarditis, remains the common name used to designate group D nonenterococcal streptococci. In some countries, the frequency of S. bovis endocarditis has increased significantly in recent years. Data from the International Collaboration on Endocarditis merged database was used to identify the main characteristics of S. bovis endocarditis and compared them with those of infective endocarditis (IE) due to oral streptococci. The database contained 136 cases of S. bovis IE and 511 cases of IE due to oral streptococci. Patients with S. bovis IE were significantly older those with IE due to oral streptococci (63+/-16 vs. 55+/-18 years, P<0.00001). The proportion of streptococcal IE due to S. bovis increased from 10.9% before 1989 to 23.3% after 1989 (P=0.0007) and was 56.7% in France as compared with 9.4% in the rest of Europe and 6.0% in the USA (P<0.00001). Patients with S. bovis IE had more comorbidity and never used intravenous drugs. Complication rates, rates of valve replacement, and mortality rates were similar in the two groups. In conclusion, this study confirmed that S. bovis IE has unique characteristics when compared to endocarditis due to oral streptococci and that it emerged in the 1990s, mainly in France, a finding that is yet unexplained.

Abstract
Management of congenital heart diseases (CHD) frequently is a diagnostic challenge. MRI, as a complement to echocardiography, plays an important role in the non-invasive evaluation of these anomalies. MRI allows high resolution anatomical evaluation of these structures in multiple planes as well as functional evaluation. These features are helpful to further characterize extra-cardiac anomalies that may be difficult to assess at US and even angiography. MRI is thus a valuable imaging tool in the evaluation of CHD.

Abstract
BACKGROUND To determine the incidence of early cardiotoxicity induced by the CHOP regimen in patients with aggressive non-Hodgkin's lymphoma (NHL) and to identify associated risk factors. PATIENTS AND METHODS A retrospective analysis included 135 consecutive patients who had been treated with the CHOP (cyclophosphamide, doxorubicin, vincristin, prednisone) regimen as first-line therapy between 1994 and 2000. The cardiac evaluation was based on a determination of the resting left ventricular ejection function (LVEF) by gated blood-pool imaging. Cardiotoxicity was defined as a significant decrease in LVEF or clinical evidence of congestive heart failure (CHF). RESULTS Twenty-seven (20%) patients developed a cardiac event within 1 year of treatment. Among these, 14 patients had clinical signs of CHF. Three patients died suddenly from presumed cardiac causes. In multivariate analysis, a cumulative dose of doxorubicin >200 mg/m(2) [odds ratio (OR) = 4.2, P = 0.005)] and age over 50 years (OR = 2.9, P = 0.03) appeared to be significant risk factors. CONCLUSION Early clinical and subclinical cardiotoxicity was frequent in patients receiving the CHOP regimen. The threshold of the cumulative dose of doxorubicin appeared to be low: at doses >200 mg/m(2), 27% of patients had cardiac events. Elderly patients appeared to be at higher risk. The development of cardioprotective strategies or alternative treatments are mandatory for aggressive NHL patients.

Abstract
AIMS Silent myocardial ischaemia is frequent in diabetic patients. The aim of this study was to compare the efficacy of thallium-201 single-photon emission computed tomography (201Tl SPECT) coupled with exercise stress testing (EST), and dobutamine stress echocardiography (DSE) in the detection of asymptomatic coronary artery disease. METHODS Fifty-six asymptomatic diabetic patients, with a known duration of diabetes > 15 years for Type 1 and > 5 years for Type 2, having at least three added risk factors, but without rest ECG abnormalities, were enrolled in this prospective study. All of them were submitted to DSE with a maximum infusion rate of 40 microg/kg per min dobutamine +/- i.v. atropine, and to 201Tl SPECT coupled with EST. Coronary angiography was performed if at least one test was abnormal. RESULTS Diabetic patients were 37 males and 19 females, aged mean (sd) 60 +/- 10 years, 10 Type 1 and 46 Type 2, with a known duration of disease of mean (sd) 17 +/- 9 years. Feasibility of DSE was 91%. No serious complication occurred during the test. Coronary angiography was performed in 26 patients (47%); 17 were abnormal (30% of the whole group): six patients had a one-vessel, six a two-vessel and five a three-vessel disease. Predictive positive value was 69% for DSE, 75% for 201Tl SPECT and 60% for EST. DSE was falsely negative in four cases vs. eight for 201Tl SPECT and nine for EST. CONCLUSIONS Asymptomatic coronary disease is common in diabetes associated with other risk factors. DSE appears useful in its detection and a good alternative to 201Tl SPECT.

Abstract
Aortic dissection (AD) is a disease with a high-risk of mortality. Late deaths are often related to complications in nonoperated aortic segments. Between 1984 and 1996, we retrospectively analyzed the data of 109 patients with acute AD (81 men and 28 women; average age 61 +/- 14 years). All imaging examinations were reviewed, and a magnetic resonance imaging examination was performed at the time of the study. Aortic diameters were measured on each aortic segment. Predictive factors of mortality were determined by Cox's proportional hazard model, in univariate and multivariate analyses, using BMDP statistical software. Follow-up was an average of 44 +/- 46 months (range 24 to 164). Actuarial survival rates were 52%, 46%, and 37% at 1, 5, and 10 years, respectively, for type A AD versus 76%, 72%, and 46% for type B AD. Predictors of late mortality were age >70 years and postoperative false lumen patency of the thoracic descending aorta (RR 3.4, 95% confidence intervals 1.20 to 9.8). Descending aorta diameter was larger when false lumen was patent (31 vs 44 mm; p = 0.02) in type A AD. Furthermore, patency was less frequent in operated type A AD when surgery had been extended to the aortic arch. Thus, patency of descending aorta false lumen is responsible for progressive aortic dilation. In type A AD, open distal repair makes it possible to check the aortic arch and replace it when necessary, decreases the false lumen patency rate, and improves late survival.

Abstract
PURPOSE Report our experience in the evaluation and follow-up of thoracic aortic coarctation with MRI and describe its role to estimate trans-stenotic flow. MATERIAL AND METHODS 43 MR examinations were performed in 30 patients (age range 15 days to 73 years) referred to our institution in the last 7 years. RESULTS MRI visualized the ascending, horizontal and descending portions of the aorta and the supra-aortic vessels in 42/43 patients. MRI clearly identified preoperatively an aortic coarctation in 11/12 cases confirmed by surgery. Postoperatively MRI depicted 4 restenosis and one aneurysm. In 5 patients MRI demonstrated pseudo-coarctation. A significant correlation was established between the maximal trans-stenotic pressure gradient when measured by Doppler US or angiography and the size of the signal void measured on cine-MR images (r=0.72; p<0.01). CONCLUSION MRI is a reliable non invasive investigation method for the diagnosis and semi-quantitative evaluation of aortic coarctation particularly when colour Doppler US is not satisfactory.

Abstract
OBJECTIVE To assess the agreement between left ventricular (LV) volumes and ejection fraction (EF) determined by two-dimensional echocardiography (2-D echo) and by cineangiography in postinfarction patients. DESIGN LV end-diastolic and end-systolic volumes indexed (EDVI and ESVI) to body surface area as well as EF were determined by both methods in all patients. SETTING Multicenter trial conducted in five university hospitals. PATIENTS 63 patients, 61 male, two female, mean age 55.5 +/- 10.4 years, suffering from a recent myocardial infarction. Eighty-one pairs of measurements were available. METHODS The results of biplane 2-D echo measures, using apical four-chamber (4C) and two-chamber (2C) views were compared to those of a 30 degrees right anterior oblique cineangiography projection, using either the apical method of discs or the area-length 2-D echo method. Moreover, eyeball EF was estimated at 2-D echo and cineangiography, and was compared to the conventional methods. The agreement between results was assessed by the Bland and Altman method. RESULTS The agreement between 2-D echo and cineangiography results was poor. Mean differences (MD) were -21.8 (EDVI, ml/m(2)), -9.5 (ESVI, ml/m(2)), and -0.9 (EF, %), respectively for 2-D echo method of discs versus cineangiography, and -23.2, -9.3, and -5.7 for area-length 2-D echo versus cineangiography. For EF (%), MD was -3.6 for eyeball cineangiography versus cineangiography, -1.3 for eyeball 2-D echo versus method of discs, and +0.30 for eyeball 2-D echo versus area-length 2-D echo, respectively. Two-dimensional echo is likely to underestimate LV volumes compared to cineangiography, especially for largest volumes. Even for EF, discrepancies are large, with a lack of agreement of 21%-25% between conventional methods, but agreement is better between eyeball EF and usual methods. CONCLUSIONS Even with modern echocardiographic devices, agreement between 2-D echo and cineangiography-derived LV volumes and EF remains moderate, and both methods must not be considered interchangeable in clinical practice.

Abstract
Congenital abnormality of the aortic arch is a diagnosis made most of the time incidentally in childhood, unless dysphagia or respiratory disorders occur before. A case of a complex aortic arch anomaly with an aneurysm of the right subclavian artery presenting as an isolated Horner's syndrome in an adult is reported herein. Magnetic resonance imaging led to this very unusual diagnosis.

Abstract
OBJECTIVE To assess the long term functional result after percutaneous mitral commissurotomy and identify the predictors of event-free survival following 10 years of experience. DESIGN Analysis of clinical, echocardiographic, and haemodynamic variables at baseline and after the procedure by univariate and multivariate analyses (Cox model). SETTING University hospital. PATIENTS 532 consecutive patients receiving percutaneous mitral commissurotomy in the same institution. RESULTS The mean (SD) follow up was 3.8 (4.0) years. Survival at 3, 5, and 7.5 years was 94%, 91%, and 83%, respectively; event-free survival was 84%, 74%, and 52%. Mitral valve anatomy was identified as the strongest independent predictor of event-free survival. Age, cardiothoracic ratio, mean pulmonary artery pressure, and mean echocardiographic mitral gradient after commissurotomy were also found to be independent predictors of long term functional results. Event-free survival was 92%, 84%, and 70% at 3, 5, and 7.5 years in patients with favourable anatomy (echo score = 1), 86%, 73%, and 34% in patients with intermediate anatomy (echo score = 2), and 45%, 25%, and 16% in patients with unfavourable anatomy (echo score = 3). In patients aged < or = 65 years, the event-free survival rate was 80%, 70%, and 45% at 3, 5, and 7.5 years v 52%, 38%, and 17% in patients aged > 65 years. CONCLUSIONS The anatomical form of the mitral valve and the patient's age were the most powerful predictors of event-free survival. Patients with intermediate or unfavourable anatomy and those aged > 65 years have low 5 and 7.5 year event-free survival rates. This must be taken into account when discussing the indications for percutaneous mitral commissurotomy; immediate mitral valve replacement is a reasonable alternative to balloon mitral commissurotomy in patients with higher risk of functional deterioration after the procedure.

Abstract
BACKGROUND Percutaneous mitral valvuloplasty with the Inoue balloon is conventionally performed with double vascular access: arterial and venous. However, in patients with a good echogenic window it may be performed with venous access only and the procedure monitored by 2D-echocardiography and colour flow mapping. This should result in early ambulation and hospital discharge with reduced arterial complications. AIMS To compare retrospectively the immediate results of percutaneous mitral valvuloplasty with the Inoue balloon in two groups of patients: Group I: venous access only (no arterial access, n = 102) and Group II: conventional double vascular access (arterial and venous access, n = 275). METHODS AND RESULTS The baseline characteristics of the two groups were comparable for age, sex, clinical, echocardiographic, radiological and haemodynamic variables. The mitral valve area (Group I: 1.1 +/- 0.3 to 1.85 +/- 0.5 cm2 vs Group II: 1.05 +/- 0.2 to 1.85 +/- 0.5 cm2, P = ns) and transmitral gradient (Group I: 11 +/- 4 to 4.7 +/- 2 mmHg vs Group II: 12 +/- 4 to 4.8 +/- 2 mmHg, P = ns) before and after mitral valvuloplasty were not statistically different. A good immediate result, defined as mitral valve area > 1.5 cm2 and mean mitral gradient < 5 mmHg with mitral regurgitation < or = 2+ at the end of the procedure, was observed in 77% of the cases in the venous-only group and 79% in the double access group (P = ns). The incidence of severe mitral regurgitation (Grade III or IV) was not statistically significant. Procedural duration (71 +/- 24 min vs 109 +/- 26 min, P < 0.01), fluoroscopic time (12.5 +/- 5.5 min vs 18.5 +/- 6 min, P < 0.01) and hospital stay (2.8 +/- 1.5 days vs 4.8 +/- 2.6 days, P < 0.001) were significantly shorter in the venous-only group than in the conventional Inoue series. CONCLUSION Single venous access balloon mitral valvuloplasty is as equally safe and effective as double vascular access. The additional advantages of single venous access are shorter procedural duration, fluoroscopic time and hospital stay. We recommend that it be performed by an experienced operator (minimum of 100 trans-septal punctures) in patients without major thoracic deformity and a good echogenic window.

Abstract
BACKGROUND AND PURPOSE Strands are thin and filamentous attachments on the cardiac valves shown by transesophageal echocardiography. Their nature and their potential for embolization are largely unknown. The objective was to estimate the risk of brain infarction in patients with mitral valve strands. METHODS Using transesophageal echocardiography, we compared the frequency of strands on native mitral valves in 284 consecutive patients admitted with brain infarction and 276 control patients, all older than 60 years. In a second part, case subjects were followed up over a 2- to 4-year period, and the risk of recurrence of brain infarction was estimated in patients with and without strands. RESULTS In the case-control study, mitral valve strands were found in 22.5% of the case patients and in 12.1% of the control subjects. In case subjects, mitral valve strands were more frequent in those with mitral valve dystrophy (52.4% versus 37.4%; P = .03). Strands were not associated with mitral valve prolapse, annular calcifications, or left atrial spontaneous echocardiographic contrast. After adjustment for age, sex, and mitral valve dystrophy, the odds ratio for ischemic stroke among patients with mitral strands was 2.2 (95% confidence interval, 1.4 to 3.6; P = .005). The frequency of strands was not different in patients with a known cause of brain infarction (24.4%) from that in patients with no other apparent cause (20.9%). During 646 per 100 person-years of follow-up, the incidence of recurrent brain infarction was 6.0 person-years in patients with strands and 4.2 in those without. In the Cox analysis, including potential confounders and poststroke treatment, mitral valve strands did not appear as independent predictors of recurrent brain infarction (relative risk, 1.3; 95% confidence interval, 0.5 to 3.0; P = .54). CONCLUSIONS The present study shows an independent association between mitral valve strands and the risk of brain infarction. However, the lack of an increased relative risk of recurrence raises doubts about the potential causal relation with brain infarction in patients aged 60 years or older.

Abstract
OBJECTIVE To assess the reliability of aortic valve area planimetry by multiplane transoesophageal echocardiography (TOE) in aortic stenosis. DESIGN Study of the diagnostic value of aortic valve area planimetry using multiplane TOE, compared with catheterisation and the continuity equation, both being considered as criterion standards. SETTING University hospital. PATIENTS 49 consecutive patients (29 male, 20 female, aged 44 to 82 years, average 66.6 (SD 8.5)), referred for haemodynamic evaluation of an aortic stenosis, were enrolled in a prospective study. From this sample, 37 patients were eligible for the final analysis. METHODS Transthoracic and multiplane transoesophageal echocardiograms were performed within 24 hours before catheterisation. At transthoracic echo, aortic valve area was calculated by the continuity equation. At TOE, the image of the aortic valve opening was obtained with a 30-65 degrees rotation of the transducer. Numerical dynamic images were stored on optical discs for off-line analysis and were reviewed by two blinded observers. Catheterisation was performed in all cases and aortic valve area was calculated by the Gorlin formula. RESULTS Feasibility of the method was 92% (48/52). The agreement between aortic valve area measured at TOE (mean 0.88 (SD 0.35) cm2) and at catheterisation (0.79 (0.24) cm2) was very poor. The same discrepancies were found between TOE and the continuity equation (0.72 (0.26) cm2). TOE planimetry overestimated aortic valve area determined by the two other methods. Predictive positive and negative values of planimetry to detect aortic valve area < 0.75 cm2 were 62% (10/16) and 43% (9/21) respectively. CONCLUSIONS Planimetry of aortic valve area by TOE is difficult and less accurate than the continuity equation for assessing the severity of aortic stenosis.

Abstract
OBJECTIVE The aim of the study was to test the efficacy of recombinant tissue plasminogen activator and streptokinase in massive pulmonary embolism, the primary endpoints being haemodynamic improvement and thrombus lysis, and the secondary endpoints efficacy and safety. DESIGN Fifty patients with massive pulmonary embolism were randomly allocated either to a 100 mg 2 h infusion of recombinant tissue plasminogen activator followed by a 20 IU.kg-1.h-1 infusion of heparin, or to a 100,000 IU.h-1 12 h infusion of streptokinase after a initial bolus of 250,000 IU over 15 min, followed by heparin infusion of 10 IU.kg-1.h-1. Total pulmonary resistance and right ventricular ejection fraction were monitored over a 12 h period. Pulmonary vascular obstruction was assessed at 24 to 48 h and 10 days after thrombolytic therapy. RESULTS Thrombolysis occurred more rapidly with recombinant tissue plasminogen activator than with streptokinase, but without any significant difference in terms of right heart haemodynamics at 12 h or in improvement of pulmonary vascular obstruction at 24-48 h or at 10 days. There was no significant difference in bleeding complication rates and no patients suffered intracranial haemorrhage. CONCLUSION These results proved that, when the full dose of streptokinase has been given over 12 h, its efficacy is as good as that of 2 h of recombinant tissue plasminogen. A further trial aimed at comparing recombinant tissue plasminogen activator and streptokinase infused over a 2 h period is needed to determine whether a similar efficacy can be obtained.

Abstract
OBJECTIVES Heparin-induced thrombocytopenia is an uncommon and severe complication of heparin therapy. Both venous and arterial thromboembolic events can occur, requiring withdrawal of the heparin therapy. When anticoagulant therapy is mandatory, recombinant hirudin can be used. METHODS We used recombinant hirudin (HBW 023) in 6 patients with heparin induced thrombocytopenia. In case of venous thromboembolism, an initial intravenous bolus (0.07 mg/kg) was followed by continuous infusion (0.05 mg/kg/h); for arterial thromboembolism the initial bolus was 0.7 mg/kg and infusion rate 0.15 mg/kg/h. When possible oral anticoagulants were started and hirudin withdrawn when the INR ratio reached 3. RESULTS The clinical course was uneventful in all 6 patients. There was no recurrent thromboembolism. Cephalin-activated coagulation time (patient/control) varied between 1.8 and 3.5 (median 2.4) during hirudin administration. Platelet count rose to the nadir (median 70 x 10(9)/l, range 15-90) reaching over 100 x 10(9)/l in all patients between the third and sixth day (median 5 days) after stopping heparin. CONCLUSION Intravenous administration of hirudin provides effective immediate anticoagulation in patients with heparin-induced thrombocytopenia, thus allowing conversion to oral anticoagulants without risking recurrent thromboembolism.

Abstract
The aim of the study was to determine the medium and long-term outcome of discrete subaortic stenosis after surgery: the data of two groups of patients classified according to age (children versus adults) at the time of diagnosis were compared retrospectively. Sixteen patients, with subaortic stenosis, were followed up clinically and by annual echocardiography for an average period of 5.7 +/- 3.6 years (range 1 day to 16 years) and patients in group II were aged 43.6 +/- 6 years (range: 3 to 17 years). Patients in group I were aged 5.4 +/- 4.2 years (range: 37 to 53 years). Four patients from group II had significant aortic incompetence. All but one patient had a membranous stenosis. Seven patients from group I and all in group II underwent surgery during the follow-up period. Four of the 5 adults in Group II were asymptomatic compared with only 1 in group I. Three patients of group II developed left ventricular dysfunction during the preoperative period compared with none in group I. Four patients in group II underwent aortic valve replacement compared with none in group I. Four of the 7 operated patients in group I had recurrence of subaortic stenosis, one of which was a tunnel form. Two reoperations were necessary in group I. There were no recurrences in group II. In conclusion, the poor outcome of adult subaortic stenosis has led to early surgical referral. This attitude should be nuanced in view of the risk of recurrence and of reoperation in childhood.

Abstract
Heparin-induced thrombocytopenia is a rare but severe complication of heparin therapy that can result in severe venous or arterial thromboembolic events and whose treatment remains partially unanswered. Recombinant hirudin is potentially effective as an antithrombotic treatment in the management of heparin-induced thrombocytopenia, given its potent antithrombin effects without known interaction with platelets. We report the results obtained with intravenous recombinant hirudin (HBW 023) administered on a compassionate basis to patients suffering from heparin-induced thrombocytopenia. Six patients suffering from heparin-induced thrombocytopenia were submitted to intravenous recombinant hirudin (HBW 023) administered at a dose of 0.05 mg/kg/hr after an initial bolus injection of 0.07 mg/kg in the case of a venous thromboembolic event, and at a dose of 0.15 mg/kg/hr with the same initial bolus injection in the case of an arterial thromboembolic event. Whenever possible, oral anticoagulation with acenocoumarol was introduced at the same time as recombinant hirudin, which was interrupted as soon as the international normalized ratio reached 3. Clinical events, particularly thromboembolism and bleeding, were noted; activated partial thromboplastin time (aPTT), and platelet count were assessed throughout the administration of recombinant hirudin. Heparins responsible for heparin-induced thrombocytopenia were porcine sodium or calcium heparinate in four cases, nadroparin in one case, and enoxaparin in one case. Thrombocytopenia was discovered on routine systematic platelet count in two patients and after the occurrence of arterial and venous thromboembolism in two patients, respectively. After discontinuation of heparin and the onset of recombinant hirudin, clinical evolution was uneventful in all patients, with no recurrence of thromboembolism, limb amputation, or hemorrhagic complication. The aPTT ratio varied from 1.8 to 3.5 (median 2.4) throughout administration of recombinant hirudin. Platelet count rose from nadir (median value 60 x 10(9), 15 to 90) to above 100 x 10(9)/L in every patient within 3-6 days (median 5), after discontinuation of heparin. Intravenous administration of recombinant hirudin ensured safe anticoagulation in patients with heparin-induced thrombocytopenia and made it possible to wait for oral anticoagulation to become efficient and platelet count to return to normal values without occurrence or recurrence of thromboembolism.

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
Thrombolytic therapy leads to more rapid dissolution of thrombi in severe pulmonary embolism than conventional heparin therapy but is considered with much reserve in elderly patients because of the risk of haemorrhage, which is thought to be potentially greater in these subjects. The object of this study was to assess the efficacy and safety of thrombolytic therapy in patients over 70 years of age with severe pulmonary embolism, compared with patients under 70 years of age with the same condition. Eighty-nine patients with severe pulmonary embolism (Miller score > 17/34) were prescribed thrombolytic therapy in the absence of a contraindication without taking age into consideration. Fifty-three were under 70 years of age (54 +/- 15; range: 18 to 70 years) and 36 were over 70 years of age (78 +/- 5; range: 71 to 88 years). Apart from age, there was no difference in the clinical presentation of the two groups. Thrombolytic therapy was initiated with streptokinase 100,000 IU/hr for twelve hours after an initial bolus of 250,000 IU or with urokinase or plasminogen tissue activator in cases with a contraindication to streptokinase. An uncomplicated course was observed in the same percentage of cases in the two groups. The Miller score and mean pulmonary pressures fell in the same way in the two groups. Three patients died during the hospital period, two aged under 70 (3.7%) and one over 7 years of age (2.7%). Major bleeding occurred in 3 subjects under 70 (5.6%) and 5 subjects over 70 (13.8%) (p = 0.29).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Analysis of 109 well documented cases of permanent total atrial paralysis reported in the literature illustrated the features of this arrhythmia which is a well defined entity consisting of suppression of all electrical and mechanical activity of both atria lasting for more than 6 months. Standard electrocardiogram reveals junctional bradycardia of about 40 bpm without any visible P waves and narrow supraventricular QRS complexes in 80% of cases. This diagnosis can only be confirmed by meticulous bipolar endocavitary recordings exploring all atrial walls without recording an auriculogram and by right intra-atrial and coronary sinus stimulation which proves to be ineffective. This disease has a male predominance in two-thirds of cases and a familial nature in 18% of cases. Seventy one per cent of affected subjects are under the age of 50 years. In 33% of cases, it is associated with Emery-Dreifuss muscular dystrophy, in which it constitutes a specific sign allowing this dystrophy to be differentiated from all other forms, especially facio-scapulo-humeral myopathy, and in 30% of cases, it is associated with a degenerative disease such as diabetes, amyloidosis or primary cardiomyopathy. Idiopathic dilatation of the right atrium is revealed in 15% of cases. The arrhythmia is responsible for syncope or faintness in 31% of cases, cerebral vascular accidents in 21% of cases and heart failure in 35% of cases. Cardiac activation is dependent on a junctional escape rhythm. The mechanism of the lesion responsible is atrial fibrosis which may extend to the sinoatrial node. The treatment of choice consists of implantation of a VVI or VVIR mode cardiac pacemaker in combination with anticoagulant therapy.

Abstract
Percutaneous mitral valvuloplasty is a non-surgical procedure for treating mitral stenosis. There are two techniques of performing this procedure, the double balloon and the Inoue techniques. The aim of this study was to compare the immediate complications of percutaneous mitral valvuloplasty in two consecutive series of unselected patients undergoing the double balloon (131 patients) and the Inoue (131 patients) techniques. The two series were comparable before valvuloplasty with respect to demographic, clinical, echocardiographic and haemodynamic criteria. The increase in valvular surface area and the decrease in pressure gradient after valvuloplasty were not significantly different (1.1 +/- 0.2 to 1.95 +/- 0.5 cm2 in the Inoue series and 1.0 +/- 0.2 to 1.95 +/- 0.5 cm2 in the double-balloon series; 12 +/- 3 to 5 +/- 2 mmHg in the Inoue series and 13 +/- 4 to 5 +/- 2 mmHg in the double-balloon series for the mean transvalvular pressure gradient). A good immediate result was defined as a valve surface are > 1.5 cm2 and < or = 2 + mitral regurgitation after the series, and this was obtained in 78% of cases in both series. Severe mitral regurgitation (3 +) requiring immediate or elective mitral valve replacement was observed in 7 cases in the Inoue series and in 5 cases in the double-balloon series (NS). One cerebral embolism occurred in the double balloon series and two systemic embolisms, one cerebral and one coronary, in the Inoue series.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two populations of aggregates are generally indentified in supersaturated solutions of biological macromolecules: small aggregates of a size which is less than 5 nm and large aggregates, the largest of which are at least one order of magnitude bigger. In order to understand the role played by the microporous network of a gel in the growth and behaviour of these different species in the prenucleation period, an in situ observation of nucleation has been carried out using either free solutions or solutions trapped in agarose gels. In a previous study, free solutions were investigated by small-angle neutron scattering (SANS) to identify the small aggregates. Optical observations, made under the same conditions, revealed the formation of an amorphous precipitate which disappeared at the end of the experiment. The sedimentation of this phase, which occurs in free solution but never occurs in gelled solution, depletes the solution bulk and this could explain why the nucleation density is higher in agarose gel than in free solution. The case of silica gel, the behaviour of which is completely different with respect to nucleation, will be discussed.

Abstract
A procedure which allows an investigator to supply a crystal with fresh mother material without inducing significant growth defects is described. This technique requires that the crystal is grown in a gelled hanging or sitting drop. An example concerning a model macromolecule, hen egg-white lysozyme, is given. Extension of this procedure to other macromolecules is discussed.

Abstract
OBJECTIVES The aim of the study was to prospectively estimate the safety of thrombolytic therapy in elderly patients with massive pulmonary embolism in comparison with that in nonelderly patients. BACKGROUND In massive pulmonary embolism, lysis of thrombi can be achieved faster with thrombolytic therapy than with conventional heparin therapy, but it is administered with great caution in elderly patients because the risk of bleeding is thought to be higher than in nonelderly patients. Yet, thrombolytic therapy might be of value in elderly patients also, in allowing potentially more rapid improvement than is achieved with conventional heparin therapy. METHODS Eighty-nine patients with massive pulmonary embolism defined as Miller score > or = 17/34 underwent thrombolytic therapy without consideration of age if they had no contraindication for such treatment. Fifty-three patients were < or = 70 years old (mean age +/- SD 54 +/- 15 years; range 18 to 70), and 36 patients were > or = 71 years old (78 +/- 5 years; range 71 to 88). Except for mean age, there were no significant differences between the two treatment groups, particularly in terms of clinical presentation, average Miller score and pulmonary artery pressure regimen. Thrombolytic therapy was administered in the form of streptokinase at a dose of 100,000 IU/h over 12 h, with an initial injection of 250,000 IU over 15 min. Heparin was introduced 12 h after initiation of thrombolytic therapy. Urokinase or tissue-type plasminogen activator was used only in case of contraindication to streptokinase. RESULTS The frequency of uncomplicated clinical course was the same in both treatment groups. Surgical embolectomy was necessary in three nonelderly patients (5.6%) and one elderly patient (2.7%). Changes in pulmonary pressure regimen and Miller score were identical in both groups. Three patients died during the in-hospital course: two nonelderly patients (3.7%) and one elderly patient (2.7%). Minor bleeding occurred in five nonelderly (9.4%) and five elderly (13.8%) patients (p = 0.74). Major bleeding was observed in three nonelderly (5.6%) and five elderly (13.8%) patients (p = 0.29). Bleeding subsequent to early invasive procedure accounted for six (75%) of eight patients with major bleeding: two nonelderly patients (one of whom died) and four elderly patients. No intracranial hemorrhage was observed. No predisposing factor for bleeding was identified, except the need for early vascular access for pulmonary angiography through the femoral approach or for percutaneous insertion of an intracaval device for partial interruption of the inferior vena cava. CONCLUSIONS Thrombolytic therapy administered for massive pulmonary embolism in patients free of contraindication yields similar results and carries a similar risk for bleeding complications in elderly compared with nonelderly patients. Limiting early invasive procedures may result in less frequent major bleeding complications.

Abstract
OBJECTIVES AND BACKGROUND To assess the long-term results of percutaneous aortic valvuloplasty and aortic valve replacement in elderly persons, two similar nonrandomized series of patients greater than or equal to 75 years old treated by one or the other method between January 1986 and March 1989 in the same institution were compared. METHODS Forty-six patients, 23 men and 23 women, with a mean age of 79.7 +/- 3.6 years (range 75 to 90) underwent percutaneous aortic valvuloplasty with use of the Cribier method (group 1). Twenty-three additional patients, 14 men and 9 women with a mean age of 78.4 +/- 2.4 years (range 75 to 86) underwent aortic valve replacement with a bioprosthesis (group 2). All of them suffered from severe calcified aortic stenosis. Clinical and hemodynamic status were similar in both groups. The mean follow-up period was 21.5 months (5 days to 60 months) in group 1 and 27.5 months (7 days to 61 months) in group 2. RESULTS Three patients (6.5%) in group 1 died within 5 days after percutaneous aortic valvuloplasty; 24 patients (52%) died during the follow-up period, 16 of whom died of recurrent cardiac failure. Of 16 patients (35%) subsequently operated on at an average of 15.8 months after percutaneous aortic valvuloplasty, 2 died at operation. Only three group 1 patients (6.5%) are still alive without subsequent aortic valve replacement. In group 2, two patients (8.7%) died postoperatively and three (13%) died during the follow-up period. All other patients (78%) are still alive and in New York Heart Association functional class I or II. The overall survival rate in group 1 was 75% at 1 year, 47% at 2 years and 33% at 5 years. In group 2, the survival rate was 83% at 1 and 2 years and 75% at 3 and 4 years. CONCLUSIONS The results of percutaneous aortic valvuloplasty do not compare favorably with those of surgery in elderly people, and this treatment should not be recommended.

Abstract
Left ventricular remodeling describes a number of geometric and structural changes that the left ventricle undergoes after myocardial infarction. Briefly, it comprises expansion of the infarct and dilatation of the healthy left ventricular segments. Its severity is related to the infarct size. These changes in ventricular geometry, in particular the dilatation, influence the long-term incidence of cardiac failure, the main secondary complication of myocardial infarction. Up to now, therapeutic interventions have been oriented to reducing the infarct size with the aim of avoiding or delaying the occurrence of left ventricular dysfunction. Nowadays, it seems possible to influence the natural process of post-infarction. Left ventricular remodeling independently of efforts to reduce infarct size. There is evidence that this process may be limited pharmacologically with angiotensin converting enzyme inhibitors. In animal studies, these agents limit remodeling and improve survival after myocardial infarction, but for the moment, despite confirmed benefits on left ventricular modeling, it is not possible to extrapolate these results in terms of clinical mortality.

Abstract
The effects of thrombolytic therapy in acute myocardial infarction are related exclusively to coronary arterial reperfusion. This is the main factor which influences myocardial salvage, the conservation of left ventricular function and, ultimately, the reduction in mortality. From the beginning of the 80s, the patency (or reperfusion) rate was arbitrarily assesses at 90 minutes. However, arterial reperfusion is a progressive phenomenon and the patency rate in a population of acute myocardial infarctions varies with time. Depending on the thrombolytic agent and the rate of administration, the patency increases at a variable rate attaining a plateau at the 4th-6th hour, the maximal patency being obtained between the 24th to the 48th hour. Therefore, assessing patency at the 90th minute of thrombolytic therapy is an approximate and relatively inaccurate method of assessing the efficacy of a given thrombolytic agent. When evaluating a thrombolytic drug administered at a certain dosage, the rate of reperfusion and the value and precocity of the plateau phase must be taken into account. The respective performances of different thrombolytics in terms of arterial patency are comparable. Nevertheless, the rate of reperfusion with Streptokinase given at the dose of 1.5 million i.v. in 60 minutes is lower than that obtained with more recent thrombolytic drugs. Streptokinase also appears to be less active on chronic thrombi. The late patency rate after the 24th hour is over 90% with nearly all thrombolytic drugs but it would seem to be less with rt-PA because of a higher reocclusion rate associated with this particular agent. The study of reocclusion requires control coronary angiography between the 24th and 72nd hour (7th day in some studies). The prevalence of this complication is influenced by several factors, especially the severity of residual stenosis after thrombolysis and the grade of perfusion obtained after the treatment: secondary reocclusion is significantly lower with long-acting and non-fibrin specific thrombolytic agents. It is approximately 2 to 5% with APSAC, Streptokinase and pro-urokinase, and two to three times greater with rt-PA. Finally, the use of more powerful antiplatelet drugs than those currently available and of specific anti-thrombin agents could reduce the rate of secondary reocclusion. Associations of thrombolytic agents, the development of thrombolytic chimera and new thrombolytic molecules could improve the efficacy of thrombolytic therapy in terms of capacity of reperfusion and tolerance, especially with respect to haemorrhagic complications.

Abstract
Seventy-one consecutive, unselected patients underwent percutaneous mitral valvuloplasty by Inoue's technique between February and November 1990. The mean age was 53 years (range 32 to 75 years). Fifteen of the 71 patients had previously undergone surgical mitral commissurotomy. Three patients had Björk aortic valve prostheses. The mitral valve surface area increased from 1.1 +/- 0.2 cm2 to 1.95 +/- 0.5 cm2 (p less than 0.01) and the mean transmitral pressure gradient fell from 12 +/- 3 mmHg to 5 +/- 2 mmHg (p less than 0.05). Grade 3+ mitral regurgitation was observed in 4 patients. There were no cases of cardiac perforation or tamponade. The only complications were related to the catheterisation and not to the technique valvuloplasty (one case of prolonged fever which regressed with antibiotic therapy, one case of arteriovenous fistula at the site of femoral artery puncture). The QP/QS ratio was 1.1 +/- 0.2 at the end of the procedure. A QP/QS ratio greater than 1.5 was observed in one patient. A left-to-right shunt was observed in 53% of cases in the immediate post-valvuloplasty period with Doppler color flow imaging. In all, 78% of patients had a satisfactory result (mitral surface area greater than 1.5 cm2 and mitral regurgitation less than or equal to 2/4). These results are identical to those observed with the double balloon technique with a lower rate of complications. The duration of the procedure (104 +/- 13 min p less than 0.02) and of radioscopy (16 +/- 8 min, p less than 0.02) were shorter than with the double balloon technique.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Immediate hemodynamic results of percutaneous mitral valvuloplasty were compared in two consecutive series of unselected patients from the same institution undergoing valvuloplasty with the double-balloon (161 patients) or the Inoue balloon (71 patients) technique. Before valvuloplasty, the patient series were comparable with regard to average age, gender repartition and most clinical, electrocardiographic, X-ray and hemodynamic variables. Poor anatomic forms of mitral stenosis were equally distributed in both series (41% vs. 45%, p = NS). The magnitude of mitral valve area increase and of mean mitral gradient decrease during percutaneous mitral valvuloplasty did not differ significantly in the Inoue balloon and double-balloon series (mean +/- SEM 1.1 +/- 0.2 to 1.95 +/- 0.5 and 1.0 +/- 0.2 to 1.97 +/- 0.5 cm2, respectively, for mitral valve area and 12 +/- 3 to 5 +/- 2 and 13 +/- 4 to 5 +/- 2 mm Hg, respectively, for mean mitral gradient). Four cases of 3+ mitral regurgitation occurred in the Inoue balloon series and 7 in the double-balloon series (p = NS). A good immediate result--defined as mitral valve area greater than or equal to 1.5 cm2 with greater than or equal to 25% in mitral valve area gain and mitral regurgitation less than 2+ at the end of the procedure--was observed in 78% of patients in both series. Three cases of tamponade due to chamber perforation and 14 cases of transient air embolism in the right coronary system due to balloon rupture were observed in the double-balloon series.(ABSTRACT TRUNCATED AT 250 WORDS)
