Abstract
We investigate from a theoretical point of view the stability of AlN2+ and GaN2+ dications produced under high static electric fields like those reached in Atom Probe Tomography (APT) experiments. By means of quantum chemical calculations of the electronic structure of these molecules, we show that their stability is governed by two independent processes. On the one hand, the spin-orbit coupling allows some molecular excited states to dissociate by inter-system crossing. On the other hand, the action of the electric field lowers the potential energy barrier, which ensures the dication stability in standard conditions. We present a detailed example of field emission dynamics in the specific case of the 11Δ states for a parabolic tip, which captures the essentials of the process by means of a simplified model. We show that the dissociation dynamics of AlN2+ and GaN2+ is completely different despite the strong resemblance of their electronic structure.

Abstract
The use of a tip-shaped sample for the atom probe tomography technique offers the unique opportunity to analyze the dynamics of molecular ions in strong DC fields. We investigate here the stability of AlN2+ and GaN2+ dications emitted from an Al0.25Ga0.75N sample in a joint theoretical and experimental study. Despite the strong chemical resemblance of these two molecules, we observe only stable AlN2+, while GaN2+ can only be observed as a transient species. We simulate the emission dynamics of these ions on field-perturbed potential energy surfaces obtained from quantum chemical calculations. We show that the dissociation is governed by two independent processes. For all bound states, a mechanical dissociation is induced by the distortion of the potential energy surface in the close vicinity of the emitting tip. In the specific case of GaN2+, the relatively small electric dipole of the dication in its ground 13Σ- and excited 11Δ states induces a weak coupling with the electric field so that the mechanical dissociation into Ga+ + N+ lasts for sufficient time to be observed. By contrast, the AlN2+ mechanical dissociation leads to Al2+ + N which cannot be observed as a correlated event. For some deeply bound singlet excited states, the spin-orbit coupling with lower energy triplet states gives another chance of dissociation by system inter-system crossing with specific patterns observed experimentally in a correlated time of flight map.

Abstract
The molecular electronic states of the SiO2+ dication have been investigated in a joint theoretical and experimental analysis. The use of a tip-shaped sample for tomographic atom probe analysis offers the unique opportunity to produce and to analyze the lifetime of some excited states of this dication. The perturbation brought by the large electric field of the polarized tip along the ion trajectory is analyzed by means of molecular dynamics simulation. For the typical electric fields used in the experiment, the lowest energy triplet states spontaneously dissociate, while the lowest energy singlet states do not. We show that the emission process leads to the formation of some excited singlet state, which dissociates by means of spin-orbit coupling with lower-energy triplet states to produce specific patterns associated with Si+ + O+ and Si2+ + O dissociation channels. These patterns are recorded and observed experimentally in a correlated time-of-flight map.

Abstract
We analyze the role of the spin-orbit (SO) coupling in the dissociative dynamics of excited alkali atoms at the surface of small rare gas clusters. The electronic structure of the whole system is deduced from a one-electron model based on core polarization pseudo-potentials. It allows us to obtain in the same footing the energy, forces, and non-adiabatic couplings used to simulate the dynamics by means of a surface hopping method. The fine structure state population is analyzed by considering the relative magnitude of the SO coupling ξ, with respect to the spin-free potential energy. We identify three regimes of ξ-values leading to different evolution of adiabatic state population after excitation of the system in the uppermost state of the lowest np (2)P shell. For sufficiently small ξ, the final population of the J=12 atomic states, P12, grows up linearly from P12=13 at ξ = 0 after a diabatic dynamics. For large values of ξ, we observe a rather adiabatic dynamics with P12 decreasing as ξ increases. For intermediate values of ξ, the coupling is extremely efficient and a complete transfer of population is observed for the set of parameters associated to NaAr3 and NaAr4 clusters.

Abstract
We investigate the relaxation of photoexcited Li(2)(+) chromophores solvated in Ne(n) clusters (n = 2-22) by means of molecular dynamics with surface hopping. The simplicity of the electronic structure of these ideal systems is exploited to design an accurate and computationally efficient model. These systems present two series of conical intersections between the states correlated with the Li+Li(2s) and Li+Li(2p) dissociation limits of the Li(2)(+) molecule. Frank-Condon transition from the ground state to one of the three lowest excited states, hereafter indexed by ascending energy from 1 to 3, quickly drives the system toward the first series of conical intersections, which have a tremendous influence on the issue of the dynamics. The states 1 and 2, which originate in the Frank-Condon area from the degenerated nondissociative 1(2)Π(u) states of the bare Li(2)(+) molecule, relax mainly to Li+Li(2s) with a complete atomization of the clusters in the whole range of size n investigated here. The third state, which originates in the Frank-Condon area from the dissociative 1(2)Σ(u)(+) state of the bare Li(2)(+) molecule, exhibits a richer relaxation dynamics. Contrary to intuition, excitation into state 3 leads to less molecular dissociation, though the amount of energy deposited in the cluster by the excitation process is larger than for excitation into state 1 and 2. This extra amount of energy allows the system to reach the second series of conical intersections so that approximately 20% of the clusters are stabilized in the 2(2)Σ(g)(+) state potential well for cluster sizes n larger than 6.

Abstract
The aim of this study was to evaluate the influence of sex on the prognosis of high risk acute coronary syndromes treated early with angioplasty. Over a period of two years, 694 consecutive patients (151 female, 543 male) underwent revascularisation within the first 24 hours of an acute coronary syndrome without permanent ST elevation (ST depression (52.5%) or relapse of angina despite medical treatment (47.5%). The females were older than the males (67.9 vs 62.3 years; p < 0.0001), smoked less (7.3 vs. 32.8%; p < 0.001) and had a higher prevalence of hypertension (53 vs. 42.1%; p = 0.017). The angiographic characteristics were equivalent in both sexes, except for a lower frequency of thrombus in the females (6.9 vs. 15.2%; p < 0.0001). All lesions were treated with endoprosthesis implantation. The angiographic success rate was comparable (94 vs. 93.7%) as was the rate of major cardiac events while in hospital (3.8 versus 4%). With an average survival of 2 years, the incidence of major cardiac events remained identical in both sexes (15.4 vs 15.7%: p = 0.43): cardiac mortality (3.2 vs 2%; p = 0.18), myocardial infarction (7.3 vs 6.7%; p = 0.37), further revascularisation (8.3 vs 7.2%; p = 0.47). The survival without major cardiac event was comparable at 1 year (87 +/- 0.1 vs 88 +/- 0.3%) and at 2 years (78 +/- 0.2 vs 83 +/- 0.3%; p = 0.58). In conclusion, the progression both in hospital and at two years with a strategy of early revascularisation for high risk acute coronary syndromes was comparable in males and females.

Abstract
AIM A prospective randomized trial was set up to evaluate contractile parameters and quality of life in patients with congestive heart failure. METHODS AND RESULTS We describe the results from 38 patients in sinus rhythm and with chronic heart failure due to congestive cardiomyopathy, prospectively randomized to optimal medical therapy (Group 1, 19 patients) or optimal medical therapy plus dual chamber pacemaker programmed to optimal AV delay (Group 2, 19 patients). At a 6 month follow-up, 7/19 patients in Group 1 had died compared with 5/19 patients in Group 2. During follow-up, there were few significant changes in evaluated parameters except for mitral regurgitation time, which was prolonged in Group 1 and shortened in Group 2. The systolic left ventricular diameter shortened significantly only in Group 2. An energy and activity questionnaire showed that the effect of DDD pacing in the latter patient population was beneficial. CONCLUSIONS From these results we may conclude that at the 6 month follow-up DDD pacing with echo-optimized AV interval programming can improve quality of life without affecting survival.

Abstract
OBJECTIVE This study sought to assess the impact of local implementation of clinical practice guidelines on the pattern of care and outcome in patients admitted to the Coronary Care Unit (CCU) with acute myocardial infarction. BACKGROUND Development of clinical practice guidelines is among the most popular of the methods intended to promote translation of results from clinical trials into routine care. However, very little is known about the actual impact on routine care of the clinical guidelines for managing patients with acute myocardial infarction. METHODS We reviewed a prospectively collected cohort of consecutive patients discharged with a diagnosis of acute myocardial infarction from S. Maria degli Angeli, a large community-based hospital in northeast Italy. Eighty-six patients treated in 1996 (before guideline implementation) were compared with 70 patients treated in 1997 (after guideline implementation) with respect to patterns of use of guideline-directed pharmacotherapies for acute myocardial infarction, diagnostic testing, length of CCU stay and clinical outcome. RESULTS The two groups were similar in male gender, age, infarct location and severity. Patients managed before guideline implementation were less likely to receive thrombolysis (36 vs 50%; p = 0.05), i.v. beta-blockers at admission (13 vs 31%; p = 0.002), oral beta-blockers at CCU discharge (45 vs 74%; p = 0.0003). When these were given, patients managed before guideline implementation received lower dosages of i.v. heparin, as manifested by a lower proportion of patients reaching adequate aPTT levels at 24 hours (14 vs 62%, p < 0.0001), and of oral beta-blockers (-50%, p < 0.0001), and higher dosage of aspirin (+100%, p < 0.0001). The time to mobilization (+1 day) and the length of CCU stay (+0.5 day) were longer in patients managed before guideline implementation (p < 0.0001). Incidence of major complications was similar between the two groups (19 vs 13%, respectively; p = ns). CONCLUSIONS Patients with myocardial infarction managed after local implementation of clinical practice guidelines were more likely to receive evidence-based effective pharmacotherapies, and to have earlier mobilization and earlier discharge from CCU. This study strongly supports the role of local implementation of clinical practice guidelines to optimize management of patients with acute myocardial infarction.

Abstract
Pulmonary embolism is a very common disease often misdiagnosed, because of variable and nonspecific clinical manifestations. Therefore it has a burden of high mortality, particularly in nonrecognized cases. Pulmonary angiography, which is usually considered the gold standard, and ventilation/perfusion pulmonary scan have shown good results in this field, but the first is costly and invasive, and both are not easily and rapidly available in all centers. Echocardiography can be helpful in the diagnosis of pulmonary embolism; transthoracic echo in particular is able to recognize indirect signs of the disease, due to acute pressure right overload; it is also possible to evaluate pulmonary artery systolic pressure by continuous wave Doppler. Transthoracic echocardiography can be negative in cases of small pulmonary embolism, in which the pressure overload and therefore haemodynamic impairment is trivial. The sensitivity and specificity of transthoracic echo is low, but its role in the diagnosis and management of pulmonary embolism may be important, because it can easily and rapidly show the presence and degree of right ventricular pressure overload and therefore it can help in addressing therapy and prognosis. Transesophageal echo may directly demonstrate thrombotic masses in the main pulmonary arteries or, less often, floating intracavitary thrombi. In this field it is showing promising results.

Abstract
Hydropneumopericardium is an uncommon condition that requires prompt diagnosis and treatment if hemodynamic compromise is present. Chest roentgenography, computerized tomography, and echocardiography provide important information for the diagnosis. In this article a new distinctive echocardiographic sign of hydropneumopericardium is described: the direct demonstration of the air-fluid interface in the long-axis precordial view.

Abstract
Although pectus excavatum (PE) is thought to impair right ventricular (RV) performance, the degree of RV dysfunction, if any, produced by this chest wall deformity remains controversial. To address this issue, we performed 2-dimensional echocardiography and chest wall radiography in 28 subjects with mild-to-severe degrees of PE to assess RV morphology and function in relation to the degree of the chest wall deformity. Measurements of RV anatomy and function obtained in these patients were compared to those of 24 normal control subjects of similar age and sex. In subjects with PE, mean RV outflow tract diameter at the aortic root level was narrower (1.4 +/- 0.3 cm/m2) and end-diastolic (10 +/- 2.3 cm2/m2) and end-systolic (5.8 +/- 1.4 cm2/m2) areas were larger than those in normal controls (1.6 +/- 0.3, 8.6 +/- 1.7, and 4.5 +/- 1.2 cm2/m2, respectively; p < 0.013). The magnitude of these abnormalities was related to the degree of the chest wall deformity evaluated on the chest radiogram (r = 0.54, 0.51, and 0.49, respectively). RV planar emptying fraction, an index of RV systolic function, was reduced in subjects with PE (42 +/- 10%) compared to the normal controls (48 +/- 10%; p = 0.047). No relation could be found, however, between this index and the severity of the chest wall deformity.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A local area network of personal computers has been operative in our Cardiology Department for seven years, to collect and retrieve on-line character-based data. At present, the network is based on 2 servers and 21 workstations. DBF and DOS files are used by a Clipper 5.2d compiled program to handle demographic data, clinical reports (32,000/year) and diagnostic codes of more than 52,000 patients. In the last two years, we started entring ECG tracings using: RS232 connection, floppy disk transfer, and modem connection with commercially available machines as well as by image scanner. We integrated our clinical database with three dedicated subsystems, written in Assembly and C languages, to manage drawings, digital ECGs and complete reports. Mass storage is provided by a 10 Gbyte magneto-optical disk autochanger physically connected to a dedicated server running an original software manager to optimize routine access to the optical disks. Interhospital network connections were established with two different institutions to allow clinical information sharing, long distance consultation and ECG transfer. The system has been found to be fast, user-friendly and suitable for daily operation of a large cardiological database. Standardized versions of the system are running in seven other cardiology institutions in Italy.

Abstract
BACKGROUND While efficacy of coronary artery bypass surgery in patients with depressed left ventricular function and myocardial ischemia is widely recognized, its results in patients in the absence of clinical evidence of myocardial ischemia remain uncertain. The purpose of this study was to evaluate the effects of coronary revascularization in comparison with conventional medical therapy in subjects with ischemic cardiomyopathy and myocardial ischemia presumed on the basis of angiographic anatomy but not demonstrated by functional testings. METHODS We selected retrospectively patients who underwent coronary angiography from 1986 trough 1993 and met the following criteria: presence of three-vessel coronary artery disease, occlusion of two and significant luminal narrowing (> or = 50%) of the third major epicardial artery, left ventricular dysfunction (ejection fraction < or = 40%), no angina or presence of mild angina, absence of inducible ischemia on exercise test and, when performed, of redistribution in the vascular territory of the patent vessel. RESULTS Thirty-one consecutive patients underwent isolated surgical revascularization treatment, while thirty medically treated patients with matched clinical characteristics were selected. Age (61 +/- 10 vs 62 +/- 9), gender (M/F 27/3 vs 24/7), NYHA class I-II (53 vs 62%) or NYHA III-IV (47 vs 38%), incidence of previous infarction (87 vs 94%), number of reversible defects in the vascular territory of the patient vessel on stress scintigraphy (0.6 vs 0.5), patent vessel (right coronary artery 7 vs 10; left circumflex 14 vs 12; left anterior descending 9 vs 9) and left ventricular ejection fraction (28 +/- 8 vs 31 +/- 7), were similar in the two groups (medical vs surgical). Surgically treated patients exhibited a lower proportion of overall cardiac deaths (7/31, 23% vs 19/30, 63%; p < 0.001), and more prolonged survival (67 +/- 9.3 vs 34 +/- 2.5 months; p = 0.04, Mantel and Cox test) than medically treated patients, respectively. The incidence of perioperative myocardial infarction was 10% (3/31). Causes of cardiac death were myocardial ischemia (9/19; 47%), sudden death (5/19; 26%) and heart failure (5/19; 26%) in medical patients, while were surgery (3 cases) and surgery related infection (1 case) (total 4/7; 57%), myocardial ischemia (1/7; 14%), sudden death (1/7; 14%) and heart failure (1/7; 14%) in surgical patients. Cox proportional hazard regression analysis with survival as the dependent variable, identified treatment, surgical or medical, as the best predictor of cardiac events (chi square improvement 9.36, p = 0.002). The next most powerful predictors were NYHA class and ACE-inhibitors treatment (chi square improvement 4.47 and 2.79, respectively). CONCLUSIONS In patients with left ventricular dysfunction, multivessel coronary artery disease and single patent but stenotic residual vessel, coronary artery bypass grafting appear to offer a better survival than medical therapy, even in the absence of clinically evident myocardial ischemia.

Abstract
Apical hypertrophic cardiomyopathy (AHCM) is characterized by primary hypertrophy localized exclusively in the apex of the left ventricle. Previous studies have indicated that AHCM results in a unique combination of cross-sectional echocardiographic (CSE) and ECG findings ('giant' T wave inversion and high R wave voltage in the precordial leads). The aims of this study were: (1) to assess the degree of AHCM in a quantitative fashion (2) to evaluate the possible relationship between apical hypertrophy, quantitatively determined, and ECG findings in patients with AHCM (3) to verify the changes in echocardiographic and ECG parameters over time (4) to define the relationship between the severity of AHCM and the clinical course of such patients. Eleven selected patients with AHCM were studied for an average 6 year follow-up period; there were seven men and four women (age from 18 to 62 years, mean 49). Apical hypertrophy was assessed quantitatively by determining the muscle cross-sectional area in the apical region, which was considered an index of myocardial mass. From the end-diastolic apical four chamber view, endocardial and epicardial contours were digitized in order to obtain the total muscle cross-sectional area of the left ventricle. The walls of the left ventricle were then divided into three regions (basal, intermediate, apical). The final value of each cross-sectional muscle area was obtained from the mean measurements of four independent and blinded observers. In AHCM the apical muscle cross-sectional area (AMA) ranged from 10.3 to 17.9 cm2, mean 13.2 +/- 2.6 cm2.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A 71 years old man, ex-smoker, moderate drinker, with a history of diabetes mellitus (type II), moderate arterial hypertension, mild aortic stenosis and moderate uniform left ventricular hypertrophy echographically documented, developed a non Hodgkin low malignancy cavum lymphoma. He has underwent chemotherapy for two years (adriamycin and other chemotherapy drugs) at moderate dosages. A complete remission of the lymphoma followed the treatment, but an initial deterioration of left ventricular function, with heart dilatation and congestive heart failure, was found. The patient improved by medical treatment, returning to the previously stable clinical condition. However a ventricular dilatation reoccurred and a paroxysmal complete atrio-ventricular block developed, necessitating the implantation of a pace maker. The patient died suddenly, during sleep, at home. This is a unique case, because of the numerous cardiac factors associated (chemotherapy and clinical findings). More probably the combination of these multiple factors and their interrelationship could explain the unique non-linear evolution of the left ventricular hypertrophy. In conclusion in these patients a very strict clinical and pharmacological follow up with serial echocardiographical examinations is fundamental and highly recommended.

Abstract
BACKGROUND The heart rate adjustment of ST depression (ST/HR Slope) has been shown by some authors to markedly improve the accuracy of treadmill exercise electrocardiogram for identifying and quantifying coronary artery disease. However, other authors have obtained different results. In the present study the results of our exercise electrocardiography laboratory are compared with the data obtained from the literature. METHODS Fifty patients (46 males and 4 females, age range 60 +/- 7 years) with suspect or certain coronary artery disease were referred for a routine treadmill exercise electrocardiogram, and subsequently underwent cardiac catheterization and selective coronary cineangiography to assess the severity of coronary obstruction. All patients exercised according to a recently reported modification of the standard Bruce protocol, proposed by Kligfield et al, for a more accurate evaluation of the ST/HR Slope, which was calculated in real time by a computerized system. Patients with coexisting valvular heart disease, cardiomyopathy, left bundle-branch block on the resting ECG, myocardial infarction within 8 weeks, diabetes mellitus, hypertensive response during exercise testing (diastolic blood pressure > 95 mm Hg and/or systolic blood pressure > 190 mm Hg), abnormalities or variations of the coronary arteries, were excluded from this study. RESULTS This method correctly identified 13 of 14 patients with multivessel coronary artery disease and 35 of 36 with less severe disease: one patient was false negative and another one false positive. Thus, in our exercise electrocardiography laboratory this approach shows a sensitivity of 93%, a specificity of 97%, a positive predictive value of 93% and a negative predictive value of 97% for the detection of severe coronary disease. CONCLUSIONS These findings suggest that, in patients selected as in this study, the ST/HR slope is a good method which improves the clinical usefulness of the treadmill exercise electrocardiogram in coronary artery disease.

Abstract
From an autopsy series of 346 patients who died of acute myocardial infarction, we selected 36 cases for whom echocardiographic data preceding death were available: 17 cases died from a rupture of the left ventricular free wall (group A) and 19 from pump failure (group B). Our aim was to investigate whether any echocardiographic parameter could predict the final event. The total wall motion score, regional wall motion score index and percent of abnormally contracting myocardium were calculated. Diastolic and systolic volumes, ejection fraction and the eccentricity index, as a rough indicator of the left ventricular shape, were also estimated. Interventricular septum and posterior wall thicknesses were also measured. All measured parameters were similar in both groups except posterior wall thickness. Even though an unavoidable selection bias is present in our series, we failed to identify any echocardiographic predictor of the final event in this patient group.

Abstract
From 71 consecutive patients with paracardiac neoplastic masses who underwent transesophageal echocardiography (TEE), obstruction of individual right upper pulmonary venous flow by compression by contiguous mass was detected by TEE in 4 patients before and disappeared after anti-neoplastic treatments. Pulmonary vein, contiguous neoplastic mass and their relation could be clearly visualized and assessed by TEE. Pulmonary venous obstruction was assessed as moderate degree by combination of Doppler flow characteristics and diameter of pulmonary vein. Before therapy, peak velocities and time-velocity integrals in obstructed right upper pulmonary venous flow were increased, whereas deceleration times of systolic flow were prolonged. After therapy, peak velocities and time-velocity integrals were reduced and deceleration times of systolic flow were shortened, with normalization of the diameter of the right upper pulmonary veins. Thus, TEE may be used to detect and evaluate pulmonary venous obstruction by neoplastic masses and its changes after antineoplastic treatments.

Abstract
A twenty-nine-year-old woman, one week after a traumatic skin laceration on the territory of the distal part of the radial artery, developed a pulsating mass suggesting a pseudoaneurysm of the radial artery. Using the duplex color Doppler echography, we clearly demonstrated the anatomical damage, the presence of the false lumen and the continuity of the vessel. These observations were of great assistance for the subsequent surgical treatment.

Abstract
BACKGROUND The effect of alteplase versus heparin in pulmonary embolism has not been studied extensively with serial pulmonary angiograms. OBJECTIVES The aim of this randomized, open trial was to evaluate the efficacy and safety of alteplase followed by heparin, versus heparin alone, in 36 patients with angiographically documented pulmonary embolism. METHODS Twenty patients were allocated randomly to a 2-h infusion of alteplase (10 mg bolus, then 90 mg over 2 h) followed by heparin; the other 16 patients were given intravenous heparin at a continuous infusion rate of 1,750 IU/h. RESULTS The vascular obstruction, assessed by the Miller index at pulmonary angiography, decreased significantly in alteplase-treated patients (p less than 0.01) from a baseline of 28.3 +/- 2.9 to a value of 24.8 +/- 5.2 2 h after the start of infusion; in the heparin group there was no change (from 25.3 +/- 5.3 to 25.2 +/- 5.4). Mean pulmonary artery pressure decreased significantly from a baseline of 30.2 +/- 7.8 mm Hg to 21.4 +/- 6.7 in the alteplase group and increased in the heparin group (from 22.3 +/- 10.5 to 24.8 +/- 11.2 mm Hg). For a subset of patients, lung scans were performed at baseline and on days 7 and 30. There were no differences between the two groups in the follow-up lung scans, but there were significant decreases from the baseline values. Bleeding occurred in 14 of 20 alteplase-treated patients and in 6 of 16 in the heparin group (p = NS). There were three major bleeding episodes in the alteplase group and two in the heparin group. Two patients died after fibrinolysis (one of acute renal failure after cardiac tamponade and one of cardiac arrest after cerebral hemorrhage) and one patient in the heparin group died of recurrent pulmonary embolism. CONCLUSIONS Alteplase resulted in a greater and faster improvement of the angiographic and hemodynamic variables compared with heparin. However, the high frequency of bleeding observed with alteplase in this trial suggests that patients should be carefully selected before thrombolytic therapy is given.

Abstract
Mediastinal paracardiac tumors may cause both cardiovascular complications and problems in differential diagnosis of cardiac diseases. Transesophageal echocardiography (TEE) may give an additional new window to mediastinal neoplasms, but only a few studies have been reported. TEE was performed in 70 patients with paracardiac neoplastic masses. The procedure was indicated to solve particular clinical problems in 20 patients, and as a prospective study on 50 unselected patients with mediastinal neoplasms. Twenty-three patients underwent follow-up studies; a total of 101 echocardiograms were recorded. The procedure was tolerated well or very well by most patients, and provided additional anatomic or hemodynamic data in every patient in group a and in 45 of 50 in group b. The additional data were relevant for clinical management in 14 of 20 patients in group a, and in 3 of 45 in group b. Based on the results of this study, TEE is useful in association with other radiologic techniques in patients with paracardiac neoplasms. As an imaging technique, it may represent a reliable alternative to computed tomography whenever the latter is not feasible.

Abstract
A case of simultaneous coronary artery spasm during coronary arteriography is reported. The patient, a 48-year-old male smoker, with an important family history of sudden death, underwent coronary angiography 5 months after anterior myocardial infarction. There were no lesions in the coronary arteries at the angiographic study. At the end of the procedure there was a sudden contemporary spasm of the anterior descending and circumflex coronary arteries. This severe condition was resolved with intra-arterial nitroglycerin. The relevance of multicoronary spasm as a cause of acute ischemic events and the possible influence of family history are discussed.

Abstract
Free jets were compared in vitro by colour Doppler flow mapping with jets striking a flat and a hemispherical surface, located 3 and 6 cm from a circular orifice (5 mm in diameter). The angles of the impinging jets were 45 degrees and 90 degrees. Flow rates from 6-52 ml.s-1 were tested (pulsatile jets, 0.5 s duration). Free jet areas (21.7 +/- 9.6 cm2) were larger (P less than 0.01) than that of impinging jets (14.3 +/- 5.6 cm2). The distance of the target was a significant factor for reducing areas of striking jets (P less than 0.001). The angle of incidence of the striking jet and the shape of the target surface were not independent factors, but they were important when interacting with flow rate (P less than 0.001). The percentage of total jet area of impinging jets occupied by swirling flow was larger for targets located at 3 cm (P less than 0.01), for a 90 degrees angle of incidence (P less than 0.01), for a flat target surface (P less than 0.05). We conclude that jets visualized in vitro by colour Doppler flow mapping are significantly modified when impinging a surface, with the interplay of several factors. This can be of importance in clinical settings.

Abstract
It has been proposed that an increased activity of cell membrane Na+/H+ exchange, mirrored by increased erythrocyte Li+/Na+ exchange, may facilitate cell hypertrophy and hyperplasia. Patients with insulin-dependent diabetes mellitus may develop a specific cardiomyopathy with systolic and diastolic abnormalities and increased thickness of the left ventricle. Therefore, we have investigated the relationships between erythrocyte Li+/Na+ and Na+/H+ exchange and echocardiographic parameters in 31 male insulin-dependent diabetics (aged 17-68), in good metabolic control. Three had untreated mild hypertension. In all patients the urinary albumin excretion rate was less than 200 micrograms min-1. Ten patients had a Li+/Na+ countertransport higher than 0.37 mmol l-1 cell h-1, the upper normal limit for our laboratory (0.49 +/- 0.10, mean +/- SD). In comparison with the patients with normal countertransport, they had increased interventricular septum thickness and relative wall thickness (h/r). End diastolic volume and cardiac index were reduced while blood pressure and urinary albumin excretion rate were similar. In the whole study group, interventricular septum thickness was significantly correlated to Li+/Na+ exchange (r = 0.61, P less than 0.001) and Na+/H+ exchange (r = 0.35, P less than 0.05), independently of the effect of age and blood pressure. Posterior wall thickness was correlated to Li+/Na+ exchange (r = 0.38, P less than 0.05) and h/r to Li+/Na+ exchange (r = 0.41, P less than 0.05) and to Na+/H+ exchange (r = 0.44, P less than 0.05). Li+/Na+ exchange was negatively correlated to cardiac index (r = -0.37, P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Diabetic nephropathy is more common in patients with a positive family history of hypertension and with elevated red blood cell sodium-lithium countertransport, a marker of risk for essential hypertension. To evaluate whether there is a relationship between this cation transport system and indicators of risk of renal and cardiovascular complications in diabetic patients before the development of clinical proteinuria, we studied 31 type 1 (insulin-dependent) diabetic patients with arterial hypertension, without clinical proteinuria and 12 normotensive normoalbuminuric diabetic patients. Sodium-lithium countertransport activity was significantly higher in hypertensive patients (0.43 +/- 0.03 mmol/l RBC x hr) than in normotensive patients (0.23 +/- 0.03; P less than 0.001). To better explore the nature of the association between this transport system and arterial hypertension, hypertensive patients were divided in two groups, with high (greater than 0.41 mmol/l RBC x hr) or normal (less than 0.41) sodium-lithium countertransport activity. The two groups of hypertensive diabetics were similar in age, sex, body mass index and blood pressure levels.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The aim of our study is to verify the reliability, reproductiveness and simplicity of a method to control cardiac surgical results. We divided 462 adult patients, operated on for acquired heart disease from October 1989 to January 1991, into five classes according to an individual score which was predictive for their operative mortality risk. The score resulted from 15 different risk factors tested with univariate and multivariate analysis against one event: operative death. The total number of deaths was 12: 2, 2, 1, 2, 5 for each class respectively. When comparing the predicted versus our observed mortality, we found no statistically significant difference, using the chi-squared test. The method we used is highly predictive for surgical mortality risk: it makes the results objectively comparable among different institutions; it is useful as a self-controlled quality method for cardiac surgical activity in any single institution.

Abstract
The familial occurrence of hypertrophic cardiomyopathy is well known; familial dilated cardiomyopathy has so far received less attention. Ten families with two or more members affected by dilated cardiomyopathy were studied by echocardiography. In 3 out of 10 families, a transverse study extended to even apparently healthy subjects was carried out, which included a total of 45 subjects. In 19 out of the 45, dilated cardiomyopathy (either symptomatic or asymptomatic) was diagnosed at echocardiography. Three more relatives, already dead of the disease, were identified through hospital records. A clinical and echocardiographic longitudinal study, lasting up to 11 years, was carried out in 5 of the 10 families. During the follow-up, 8 out of 19 patients who, at first examination were affected by dilated cardiomyopathy, died, one improved, 3 remained in stable condition and 7 were lost at follow-up. One of two patients who presented echocardiographic findings suggestive of border-line dilated cardiomyopathy returned to normality and the other developed dilated cardiomyopathy. The clinical and echocardiographic findings in our patients, and in their relatives, suggest the possibility that idiopathic dilated cardiomyopathy may be a multifactorial disease in which genetic factors might play a variable role.

Abstract
We reviewed transthoracic (TTE) and transesophageal (TEE) echocardiograms of 100 consecutive patients: 63 male, 37 female, mean age 50 years (range 16-83 years), 32 with neoplastic disease, 18 aortic disease, 28 mitral valve disease, and 22 with other diseases. Absence or presence of mitral regurgitation (defined as mild, moderate, or severe) was assessed. TEE showed mild mitral regurgitation in 26 patients where TTE was negative. The overall estimate of regurgitant lesion severity was concordant at TEE and TTE in 64% of cases. The overall estimate of regurgitant lesion severity was also greater by one grade in 1% of cases at TTE, and in 35% of cases at TEE. Maximal digitized jet areas were 3.60 +/- 6.35 cm 2 at TTE and 3.04 +/- 3.79 cm 2 at TEE (P = NS). Correlation was r = 0.69 (TEE = 0.41 TTE + 1.55; P less than 0.001). TEE yielded a higher prevalence of mitral regurgitation than TTE with a trend toward greater overall estimate of mitral regurgitation at the semi-quantitative analysis. TTE and TEE showed similar mean results at the quantitative assessment of maximal jet areas. However, a highly significant random variability was observed in quantifying mitral regurgitation at TEE.

Abstract
The goals of this study were: 1) to determine and compare the prognostic utility of exercise 201Thallium scintigraphy with coronary angiography in patients with residual ischemia at the symptom limited bicycle exercise testing performed at hospital discharge after a first uncomplicated acute myocardial infarction 2) to verify the ability of perfusion scintigraphy to identify better than coronary angiography a subset of these patients at low risk for future events, despite the ischemic response at the exercise stress testing. Accordingly, follow-up data were obtained prospectively for 72 consecutive patients with adequate left ventricular rest systolic function, and with exercise induced greater than or equal to 1 mm ST-segment depression and/or typical angina pectoris. A planar 201Thallium scintigraphy and coronary angiography were performed within 2 months after acute myocardial infarction. By 31 +/- 29 months 38 patients had no events, while 34 experienced a cardiac event: 3 died of cardiac causes, 2 had nonfatal recurrent myocardial infarction, 29 were rehospitalized for severe class III or IV angina pectoris (4 were treated medically, 25 were revascularized: 20 had coronary bypass surgery, 5 coronary angioplasty). Each of the 3 angiographic classification of coronary artery disease (number of vessels with greater than or equal to 70% reduction of luminal diameter, jeopardy score and Gensini score) accurately identified patients with subsequent cardiac event by Mantel and Cox analysis (respectively p = 0.01, p = 0.0000, p = 0.002). Among 201Thallium variables, the number of segments demonstrating redistribution on delayed images (p = 0.0000), the number of segments with persistent defect (p = 0.0003) and increased 201Thallium uptake by the lungs (p = 0.0100) effectively stratified the probability of survival by the same analysis. Furthermore, the number of perfusion defects, either transient or persistent, with exercise 201Thallium scintigraphy provide additive prognostic information to any of the 3 angiographic coronary artery disease classifications considered. On the contrary, when 201Thallium stress findings are known, coronary angiography data in general are not additive in risk stratification. 17 patients with no reversible perfusion defect remained stable at follow up (52 +/- 28 months) despite development of typical angina pectoris (11/17) and/or ischemic ST segment depression (12/17) during exercise testing.(ABSTRACT TRUNCATED AT 400 WORDS)
