Abstract
BACKGROUND Although the development of noncardiogenic pulmonary edema or pulmonary reimplantation response (PRR) after lung transplantation has been well described, the incidence has not been established and the relationship of PRR to clinical risk factors has not been analyzed. STUDY OBJECTIVES (1) To describe the incidence of PRR in lung transplant recipients, (2) to identify the predictors of PRR, (3) to examine the correlation of suspected predictors with the severity of PRR, and (4) to evaluate the impact of PRR on morbidity and mortality of lung transplant recipients. DESIGN Retrospective review of clinical records and radiographic studies. SETTING Tertiary care referral center. PATIENTS Ninety-nine consecutive patients with end-stage lung disease undergoing lung transplantation between February 1990 and October 1995. METHODS Review of clinical records and postoperative chest radiographs of all lung transplant recipients to identify patients who experienced PRR. Chest radiographs of patients with PRR were graded for severity on a scale of 0 (none) to 5 (very severe). Demographic, pre- and perioperative factors were also evaluated along with short- and long-term survival of patients with PRR. RESULTS Fifty-six of 99 lung transplant recipients (57%) experienced PRR. The median ischemia time of patients with and without PRR was 168 and 180 min, respectively (p = 0.62). The incidence of PRR was 51% in patients without preoperative pulmonary hypertension, 78% in mild to moderate pulmonary hypertension, and 58% in patients with severe pulmonary hypertension (p = 0.10). Incidence and severity of PRR was similar in patients receiving right, left, or double-lung transplantation. Similarly, age and sex of the recipients and underlying lung disease did not affect the incidence or severity of PRR. The incidence and severity of PRR was higher in patients undergoing cardiopulmonary bypass during lung transplantation. Patients with PRR had prolonged duration of mechanical ventilation and ICU stay. Overall, PRR did not affect the survival of the patients. However, survival of female lung transplant recipients was significantly better than male recipients (median survival, 60 vs 21 months; p = 0.02). CONCLUSIONS Acute pulmonary edema or PRR occurs frequently (57%) after lung transplantation. In this series, PRR was not associated with a prolonged ischemia time, preoperative pulmonary hypertension, the type of lung transplant, underlying lung disease, or age or sex of recipients. However, use of cardiopulmonary bypass during surgery was associated with increased incidence and severity of PRR. Also, the development of PRR resulted in prolonged mechanical ventilation and a longer ICU stay, but did not affect survival. Female lung transplant recipients survived significantly longer than male recipients. The reason for this difference in survival is unclear.

Abstract
In a double-blind, placebo-controlled study, the central and peripheral hemodynamic effects of 100 mg oral flosequinan and the impact of this drug on neurohormonal activation were noninvasively evaluated in 18 patients with congestive heart failure, after the first administration and after 10 days of treatment. No significant hemodynamic and neurohormonal changes were observed after acute administration. After 10 days, flosequinan produced central and peripheral hemodynamic improvement characterized by an increase in left ventricular circumferential fiber shortening velocity (+12%), a decrease in total systemic resistance (-36%), and an increase in leg blood flow (+37%). No significant changes were observed in heart rate and arterial pressure in patients receiving flosequinan, though a slight increase in heart rate (+17%) was recorded. Despite these favorable hemodynamic effects, flosequinan significantly increased plasma norepinephrine (+38%) and plasma renin activity (+13%) after 10 days of treatment. Thus, the beneficial central and peripheral hemodynamic effects of flosequinan are accompanied by activation of the sympathetic and reninangiotensin systems. This might be related to the unfavorable effects of the drug on survival in patients with heart failure.

Abstract
Blood flow to working skeletal muscle is usually reduced during exercise in patients with congestive heart failure. An intrinsic impairment of skeletal muscle vasodilatory capacity has been suspected as a mechanism of this muscle underperfusion during maximal exercise, but its role during submaximal exercise remains unclear. Therefore, we studied by transcutaneous Doppler ultrasonography the arterial blood flow in the common femoral artery at rest and during a submaximal bicycle exercise in 12 normal subjects and in 30 patients with heart failure. Leg blood flow was lower in patients than in control subjects at rest [0.29 +/- 0.14 (SD) vs. 0.45 +/- 0.14 l/min, P < 0.01], at absolute powers and at the same relative power (2.17 +/- 1.06 vs. 4.39 +/- 1.4 l/min, P < 0.001). Because mean arterial pressure was maintained, leg vascular resistance was higher in patients than in control subjects at rest (407 +/- 187 vs. 247 +/- 71 mmHg.l-1.min, P < 0.01) and at the same relative power (73 +/- 49 vs. 31 +/- 13 mmHg.l-1.min, P < 0.01) but not at absolute powers. Although the magnitude of increase in leg blood flow corrected for power was similar in both groups (31 +/- 10 vs. 34 +/- 10 ml.min-1.W-1), the magnitude of decrease of leg vascular resistance corrected for power was higher in patients than in control subjects (5.9 +/- 3.3 vs. 1.9 +/- 0.94 mmHg.l-1.min.W-1, P < 0.001). These results suggest that the ability of skeletal muscle vascular resistance to decrease is not impaired and that intrinsic vascular abnormalities do not limit vasodilator response to submaximal exercise in patients with heart failure.

Abstract
Right intrapericardial retroatrial haematomas are usually discovered in an acute context of tamponade, following cardiac surgery. The original feature of this case was the asymptomatic nature of a right retroatrial haematoma, after surgical closure of an ostium secundum atrial septal defect, with a free interval of more than 20 years between the surgical procedure and the first relatively minor symptoms, consisting of supraventricular arrhythmias. It can be difficult to determine the intra- or extra-atrial topography of a right-sided mass by transthoracic echocardiography. On the other hand, transoesophageal echocardiography and ultrafast CT can provide a precise topographic diagnosis and appear to be complementary to assess the nature of pericardial masses.

Abstract
OBJECTIVE We assessed the production of eicosanoids and the effects of very low dose aspirin in patients with stable angina under basal conditions and during rapid atrial pacing. BACKGROUND Platelet activation occurs in acute ischemic syndromes but is still controversial in stable angina. Very low dose aspirin is known to be platelet selective and can be used to test the hypothesis of the platelet origin of increased thromboxane production in stable angina. METHODS Urinary excretion of eicosanoids was measured in 42 patients, including 24 patients with and 18 patients without coronary artery disease. The effects of 50 mg/day of aspirin were measured at rest and during pacing-induced ischemia in 10 patients with stable angina and were compared with a similar group of patients not treated by aspirin. RESULTS Excretion of 11-dehydro-thromboxane B2 was 2.6 times higher in patients with stable angina than in healthy subjects (mean [+/- SEM] 74.8 +/- 13.0 [24 patients] vs. 29.0 +/- 5.4 [18 patients] ng/mmol of creatinine, p < 0.01). Urinary prostacyclin metabolite levels did not differ between the two groups. Treatment for 8 days with 50 mg/day of aspirin inhibited platelet cyclooxygenase, as reflected by the 97% reduction of in vitro serum thromboxane production. This aspirin regimen normalized the level of urinary thromboxane metabolites in patients with angina (17.3 +/- 3.4 ng/mmol of creatinine [10 patients], p < 0.001 from baseline level before treatment) and did not change prostacyclin metabolite levels. Atrial pacing in patients with angina not treated with aspirin caused lactate and thromboxane release into the coronary sinus. In patients with very low dose aspirin therapy, pacing did not cause thromboxane release despite inducing myocardial ischemia. However, fractional lactate extraction decreased less sharply in patients with than without aspirin therapy. CONCLUSIONS Thromboxane production is greatly increased in patients with stable angina. Very low dose aspirin administered to these patients reduces thromboxane synthesis to normal levels, preserves prostacyclin biosynthesis and prevents acute thromboxane release into the coronary circulation during pacing-induced ischemia. Our data suggest that platelets (not monocytes/macrophages) are activated in stable angina to produce thromboxane.

Abstract
A 40-year-old woman with a significant neurological history presented with right hemiparesia, paraesthesia of the right upper member and of the hemiface. Computer tomography scanning revealed hypodensity along the right lateral ventricle which corresponded to the left hemiplegia which had developed when she was 20 years old. Arteriography of the four cervical axes was normal. Echocardiography visualized an aneurysm of the membraneous septum free of thrombosis without ventricular septal defect. The embolism was thought to be of cardiac origin and a decision was taken to correct it by surgery. Ten years after surgical repair no other neurological event has occurred.

Abstract
The role of endothelin, a powerful vasoconstrictor, was studied in coronary spasm. A methylergonovine stress test was performed in patients with normal coronary angiography. Patients who developed spasm (Group I, n = 6) were compared with those who did not (Group II, n = 6). Plasma endothelin was measured at 8, 11 a.m., 2 p.m., 4, 7, 9, 11 p.m. and 1 a.m. The stress test was carried out at 17 hours and an additional endothelin measurement was performed during spasm in positive cases. The clinical characteristics of the two groups were comparable especially with regards to cardiovascular risk factors. Except for the value recorded during coronary spasm, the plasma endothelin levels were significantly higher in the group with coronary spasm. A time-dependent variation was observed in both groups with higher endothelin levels in the morning. In group I the plasma endothelin levels were higher under basal conditions and during spasm in patients with spastic angina.

Abstract
The role of thrombosis in the pathogenesis of unstable angina has been demonstrated experimentally. This retrospective study was designed to identify the potential usefulness of fibrinolytic treatment in this situation. The following parameters were evaluated in 74 patients (62 men, 12 women; mean age: 60 +/- 10.2) with primary unstable angina: the course of unstable angina (Braunwald classification), risk factors, electrocardiographic changes, echocardiographic segmental kinetics, coronary arteriography findings, treatment used and outcome with a minimum follow-up of 3 months (mean: 6.3 months). Thirty nine per cent of class I patients and 18% of classes II and III were stabilised by medical treatment only. This accounted for 18 patients in our series (24%). The other patients (76%) required one or more reperfusion techniques (thrombolysis: 5 patients; angioplasty: 42; bypass: 19). Serious complications were seen in 3 patients: myocardial infarction: 2 postoperative (including one fatal) and 1 occurring 24 hours after angioplasty followed by cardiogenic shock and death. Five patients required thrombolytic treatment leading to clinical stabilisation enabling an additional procedure (angioplasty or bypass). No complications of thrombolytic treatment were seen. Thus thrombolytic treatment appears to be useful for the stabilisation of unstable angina and enables subsequent radical treatment under better conditions.

Abstract
Perfusion-induced myocardial ischaemia is observed in several situations: chronic coronary insufficiency, unstable angina, myocardial infarction, and during coronary angioplasty or bypass surgery. Oxygen-derived free radicals are liberated in large quantities during myocardial reperfusion ischaemia. Though very toxic in experimental studies, the responsibility of these free radicals in myocardial injury remains to be demonstrated clinically. Oxidant stress, characterised by an imbalance between the free radical attack and insufficient cellular defense seems partially responsible for reperfusion arrhythmias and post-ischemic stunning. On the other hand, its role is less evident in prolonged myocardial ischaemia causing irreversible myocardial lesions such as infarction. Antioxidant therapy is under evaluation in clinical trials. There are several options: some prevent the formation of free radicals by inhibiting the biochemical reactions which may produce them or by limiting the intervention of the neutrophils--the "fulcrum" of free radicals formations. Other antioxidant therapies inactivate free radicals as they are formed by promoting their degradation or their neutralisation. Experimental data is profuse and discordant. The models are very different. The first clinical trials are under way using either specific antioxidant molecules or molecules having other beneficial effects: in the latter case, the benefit of the antioxidant action is more difficult to demonstrate. Antioxidant therapy could play a role in surgical myocardial protection, especially of transplant organs, in very early forms of ischaemia. It could also prevent the pejorative hemodynamic consequences of myocardial stunning of the border zones of infarction, so enabling patients to survive a difficult period. The results of on-going studies should clarify the role of antioxidant therapy in reperfusion-induced myocardial ischaemia.

Abstract
A provocation test using methylergometrine was carried out in patients with a normal coronary angiogram. Patients exhibiting spasm (Group 1, n = 6) were compared with non-spasm patients (Group II, n = 6). The endothelin concentration was determined in all cases at 0800, 1100, 1400, 1600, 1900, 2100, 2300 and 0100 h. The provocation test was carried out at 1700 h and an additional determination was made during spasm if the test was positive. The two groups had similar clinical characteristics and did not differ in terms of risk factors. Apart from the value recorded during spasm, the endothelin plasma level was significantly higher in Group I. A time x measurement interaction was noted in both groups, with a higher endothelin level in the morning. The endothelin level increased significantly during spasm in Group I patients. The plasma concentration of endothelin appeared to be higher in the basal state and during spasm in patients exhibiting spastic angina.

Abstract
The action of a phosphodiesterase inhibitor, RGW 29 38, was analysed experimentally. A preliminary study with guinea pig isolated heart, using Langhendorf's method, revealed a cardiotonic effect, though less than with isoprenaline and dobutamine, with which it was compared. The inotropic action of the compound was then studied using human isolated atrium. The model is described. It consisted of measurement by a strain gauge of the contractions obtained in a stimulated atrial fragment obtained during a surgical procedure. The following parameters were analysed, expressed as percentage increase in relation to baseline conditions: maximum tension developed, positive dP/dt and negative dP/dt. The effect of RGW (n = 6) was compared with that of isoprenaline (n = 7). RGW caused an increase in maximum tension of 195% +/- 91%, in positive dp/dt of 110% +/- 72% and in negative dp/dt of 168 +/- 54%. This increase was, however, less than that seen in the isoprenaline group. Thus RGW had a definite positive inotropic effect on guinea pig isolated heart and human isolated atrium, though less than that of the catecholamines with which it was compared. Isolated human atrium appears to be a useful study model, in particular for analysis of the inotropic action of drugs.

Abstract
A 68-year-old woman was admitted for major dyspnoea. A transoesophageal echocardiogram was performed after the occurrence of acute circulatory shock. During the examination, the patient was under mechanical ventilation. We found a thrombus that had almost occluded the right pulmonary artery and which was later confirmed by selective angiography. Despite treatment, the patient died 2 days later; autopsy confirmed the thrombus in the right pulmonary artery.

Abstract
The results of several studies, mostly without controls, have suggested that betablockers, administered at progressively increasing doses, may be beneficial in cardiac failure. Based on this hypothesis, betablockers with a peripheral vasodilator effect, such as Nebivolol, could be particularly valuable in this indication. A preliminary study of its tolerance, haemodynamic and neurohormonal effects was carried out with a noninvasive methodology in 12 patients with cardiac failure in sinus rhythm, 8 men and 4 women (average age 53 +/- 12 years), all of whom had Class III or IV symptoms according to the NYHA Classification. The protocol had 2 phases: the first was an open phase during which Nebivolol was administered at a dose of 1 mg/day for 48 hours then 2.5 mg/day for 72 h. In the second phase, the patients were randomly separated into 2 groups, one to receive placebo and the other 2.5 mg for one week then 5 mg of Nebivolol for the 5 remaining weeks. The heart rate decreased significantly from 70 +/- 3 to 63 +/- 4 beats/min (p < 0.01) with Nebivolol 1 mg/day without further slowing at the 2.5 mg dosage. During the randomised phase, the heart rate remained stable in the Nebivolol group but increased to its initial value in the group given placebo. No aggravation of symptoms was observed in the Nebivolol group. No significant changes in cardiac output, parameters of cardiac loading or contractility could be demonstrated after 6 weeks' treatment. During submaximal exercise testing, plasma concentrations of catecholamines and atrial natriuretic factor tended to be higher with Nebivolol than with placebo.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Hypercholesterolemia is a major risk factor in coronary heart disease (CHD) and ischemic stroke. However, there is no general agreement on the usefulness of systematic screening of patients with hyperlipidemia by stress exercise electrocardiogram (ECG). The feasibility of this approach would depend on selecting patients with a high risk of CHD, since the sensitivity and specificity of the test depends on the prevalence of the disease. In view of the association of CHD and ischemic stroke, we undertook a study to determine whether the presence of atherosclerosis in the carotid arteries was predictive of a positive exercise ECG in a group of 778 asymptomatic patients referred to their hyperlipidemia. We a much higher percentage of positive exercise ECG in patients with carotid atherosclerosis in our ultrasonographic examinations. In a multiple regression analysis which included 13 parameters (age, sex, body mass index, arterial blood pressure, lipid parameters, serum level of glucose, smoking status and the severity of carotid lesions), the strongest predictors of a positive exercise ECG test were age (P = 0.014) and the degree of carotid atherosclerosis (P = 0.010). We therefore conclude that hyperlipidemic patients with atherosclerotic lesions on carotid arteries would benefit most from screening by the exercise ECG.

Abstract
BACKGROUND The complement system and arachidonic acid metabolites are involved in severe myocardial ischemia such as myocardial infarction. Furthermore, there is experimental evidence for C5a participation in thromboxane production. METHODS AND RESULTS We examined whether C5a and thromboxane are produced during brief and reversible episodes of myocardial ischemia induced in patients with stable angina. Twenty-five patients underwent either atrial pacing or percutaneous transluminal coronary angioplasty associated with arterial and coronary sinus blood sampling. Rapid atrial stimulation of patients with effort angina caused significant ST segment depression (delta ST = -1.7 +/- 0.2 mm), decreased fractional lactate extraction (from +12.8 +/- 2.5% baseline to -13.7 +/- 4.6% at peak ischemia, n = 13, p less than 0.001), and increased coronary sinus plasma thromboxane B2 levels (from 345 +/- 85 pg/ml baseline to 1,684 +/- 64 pg/ml at peak ischemia, p less than 0.01). Changes of fractional lactate extraction correlated significantly with changes of coronary sinus plasma levels of thromboxane B2. There was no change of coronary sinus 6-keto-PGF1 alpha levels. Similar pacing of control subjects (n = 6) did not cause release of lactate or thromboxane. Seventeen other patients underwent exercise testing with noninvasive measurements of thromboxane and prostacyclin metabolites in urinary samples collected before and after the test. No detectable increase of urinary 11-dehydrothromboxane B2 was measured in patients with stable angina after exercise-induced myocardial ischemia. However, basal 11-dehydrothromboxane B2 levels were significantly higher in patients with angina (105 +/- 25 pg/mmol creatinine, n = 9) than in control patients (45 +/- 8 pg/mmol creatinine, n = 8, p less than 0.05 between groups). Coronary sinus plasma levels of the anaphylatoxin C5a always remained below 4 ng/ml in patients undergoing pacing. More severe myocardial ischemia after coronary angioplasty (percent lactate extraction decreased from +24.8 +/- 2.7% baseline to -41.6 +/- 22.4% at peak ischemia, p less than 0.05) was not associated with C3a or C5b-9 generation. In all patients, there was neither platelet sequestration nor platelet alpha-granule release (no changes of beta-thromboglobulin/platelet factor 4 levels) into the coronary sinus plasma. CONCLUSIONS Patients with stable angina have chronically increased thromboxane synthesis as assessed by excretion of urinary metabolites. Thromboxane is acutely released into the coronary sinus during pacing-induced ischemia without significant intracoronary platelet aggregation. Complement does not appear to be activated in stable angina during brief and reversible episodes of myocardial ischemia and does not contribute to thromboxane production.

Abstract
Coronary arteries of anomalous origin with subsequent coursing between the aorta and pulmonary trunk can cause ischaemia, infarction or sudden death. However, reports of surgical correction are sparse due to the rarity of ante-mortem diagnosis. We report two cases in which symptoms were related to anomalous origin of a non-atherosclerotic coronary artery. Surgical repair was performed to prevent sudden death or recurrent ischaemia.

Abstract
The first attempts at treating heart failure with beta-blockers were made almost 15 years ago. A few studies, some of them controlled and randomized, suggest that beta-blockers may improve the patients' comfort, their physical capabilities, their haemodynamic values or even their life expectancy. However, the results published are conflicting. The mechanism of the beneficial effects of beta of beta-blockers is controverted, the most widely accepted hypotheses being that they protect against the toxic effect of catecholamines, act as antiarrhythmics and prevent the down regulation of beta-adrenoceptors. Numerous questions concerning the exact indications of these drugs, the nature and dosage of the beta-blocker to be used, the possible combinations with other therapies and the responses to be expected remain to be answered. When available, the results of multicentre trials currently in progress will be of assistance to determine the role of beta-blockers in the overall management of heart failure.

Abstract
In this retrospective study the antiarrhythmic of 85 patients suffering from sustained and recurrent attacks of ventricular tachycardia is analysed. Among these patients, 48 had ischaemic heart disease, 18 had right ventricular arrhythmogenic dysplasia, 9 had dilated cardiomyopathy and 2 had complex heart disease; in 8 patients the tachycardia was idiopathic. Two hundred and seventy-two antiarrhythmic treatments administered orally alone or in combination were studied. Their effectiveness was evaluated on the clinical course of the disease, on the résults of Holter recordings and, in some cases, on electrophysiological exploration. The mean follow-up period was 50 months. Each patient received 3.2 antiarrhythmic treatments on average. The effectiveness and side-effects of these treatments are analysed retrospectively, but the relative effectiveness of a treatment compared to another cannot be extrapolated to a new patient. Prescription in this field is purely empirical. The recent amiodarone-flecainide combination has been the most frequently used antiarrhythmic treatment in recent years. It was given to 33 patients in this series and proved effective in 21 patients followed up for 22 months.

Abstract
A 25-year old female patient was admitted to hospital for respiratory failure with pulmonary miliary. Subsequently, clinical signs of pericardial tamponade developed. Echocardiography showed a tumour of the right atrium. Malignancy of the tumour was strongly suspected on the basis of magnetic resonance findings. At surgery, the tumour could not be removed and multiple biopsies showed that it was an angiosarcoma with metastases in the lymph nodes and the lungs, the latter presenting as carcinomatous miliary. This case is of interest because of the unusual way the tumour was discovered with a possible alternative diagnosis of cardiac tuberculoma, and because of the usefulness of magnetic resonance imaging to diagnose cardiac tumours and evaluate the extension of those which are malignant.
