Abstract
INTRODUCTION In patients undergoing cardiac surgery, preoperative concerns, expectations of the impact of surgery, anticipated recovery timelines, and pre- and postoperative education, which impact recovery and quality-of-life, are not well documented. These factors are important with the increase in virtual consultations, the availability of internet-based information and increased use of minimally invasive surgical procedures. METHODS Patients who underwent cardiac surgery between January 2016 and December 2019 took part in an online survey examining preoperative concerns, information provision, use of digital channels, satisfaction with surgery, impact on health and resumption of daily activity. 80 patients completed the survey. RESULTS There was a high rate of overall post-surgical satisfaction (86%); 71% of respondents reported an improvement in physical health, 45% in mental health and 70% in their quality-of-life. The usefulness of information provided by the National Health Service varies across different stages of the patient experience. Although approximately 90% of respondents found the information provided at each stage at least 'somewhat' helpful, the proportion who found the information 'very' helpful was lower (68% for pre-procedure; 55% for post-discharge). The majority (79%) said that they felt prepared for their operation. Survey responses highlighted areas of lower understanding, including survival rate, levels of postoperative pain, duration of hospital stay and when the patient could return to normal physical activity. CONCLUSIONS Levels of satisfaction with the outcomes of heart surgery are high, and the majority of patients report positive health outcomes. However, there is room for improvement in patients' understanding of survival rate and level of pain post-procedure. There is also a clear desire among patients for a more surgical team-based face-to-face consultation.

Background
While canonical adipose tissue (AT) depots have been extensively characterised in health and disease, comparatively little is known about the pathological changes affecting the perivascular AT’s (PVAT) physiology during obesity.
Purpose
The aim of this study was to study the impact of obesity on the secretory activity of the murine PVAT.
Methods
We exploited proteomics to profile the secretome of peri-aortic and canonical AT depots in wild-type (wt) and obese (ob/ob) mice. In parallel, fat tissues were processed for biochemical and histological analysis and mechanistical experiments were performed in vitro on primary neuronal cultures.
Results
Proteomics on ATs conditioned media from wt mice revealed that each fat depot displays a unique secretory profile. The enrichment of neuronal cell-adhesion molecules detected in PVAT secretomes reflected a higher content of intra-parenchymal sympathetic projections compared to non-perivascular ATs. A significant decrease of the same neuronal proteins in PVAT conditioned media from ob/ob mice was found to be associated with a substantial reduction of the perivascular sympathetic innervation. Intriguingly, a similar decrease of sympathetic markers was detected in the epicardial AT from obese patients. Mechanistically, the conditioned media from ob/ob AT explants was found to exert a deleterious effect on the axons of primary sympathetic neurons in vitro, indicating that this neuropathy is due to local alterations of the PVAT secretome that detrimentally impact on the embedded sympathetic neurites. Among proteins significantly down-regulated in the secretomes of ob/ob PVAT samples, neuronal growth regulator 1 (Negr1) was found to promote axonal elongation and branching on sympathetic neurons in vitro. Administration of recombinant Negr1 also partially restored the neurotrophic effect of ob/ob AT secretomes on sympathetic axons both in vitro and in vivo.
Conclusions
Obesity-related alterations in the secretome of PVAT severely affect the homeostasis of the perivascular environment, leading to a loss of perivascular sympathetic innervation. A novel neurotrophic role is unveiled for Negr1, whose locus has been associated with human obesity.

Abstract
Background Nurses, as the largest group of health professionals, are at the frontline of the healthcare system in response to COVID-19 epidemic. This study aimed to evaluate the nurses’ certainty and satisfaction with medical gloves when exposed to coronavirus in Fars province, south of Iran. Methods Using convenience sampling, 400 hospital nurses during the COVID-19 outbreak were selected from eight hospitals of Shiraz University of Medical Sciences (SUMS). A questionnaire about glove reliability, including protection in tasks, durability, integrity and tear resistance, feeling fearful, and focusing on duties, and the nurses’ anxiety regarding their infection with coronavirus was distributed to the selected nurses to complete. 375 questionnaires were completed (response rate of 93.75%). Among the participants, 180 (48%) were in the corona section and 195 (52%) were hardly possible to have contact with coronavirus pneumonia patients. Results The mean score (SD) of anxiety about infection with COVID-19 for nurses in the COVID-19 section and those in the non-COVID-19 section were 6.08 (2.8) and 4.56 (2.58), respectively (p < 0.05). The mean duration of gloves usage in a day was almost similar in the two groups (about 5 h), but the number of glove replacements was significantly higher among the nurses in the corona section (6 times) compared to those in the non-corona section (3 times). The two groups were also significantly different regarding glove protection in daily tasks and glove durability. Conclusion The nurses in the corona section had more concerns about medical gloves as a type of personal protective equipment. In addition to health education on controlling and preventing the spread of diseases, raising awareness about the reliability of personal protective equipment can improve nurses’ performance.

Abstract
While limited investigations have been reported on CTC elimination and its profits, recently, some new works were reported on detection followed by the destruction of CTCs. Limitations and complications of CTC capturing procedures have highly reduced the chance of selective destruction of CTCs in the bloodstream in the therapeutic guidelines of the patients. Here, we selectively deactivated the invasive function of CTCs during their circulation in the bloodstream by exposing the whole blood to pure positive electrostatic charge stimulation (PPECS). Our treatment suppressed pulmonary metastasis and extended the survival of the mice had been intravenously injected by electrostatically deactivated 4T1 breast cancer CTCs. Moreover, the number of cancerous lung nodules was drastically reduced in the mice injected by treated CTCs in comparison with the non-treated cohort. Evaluating the side effect of the PPECS on the blood components revealed no major effect on the functional properties of the white blood cells, and just a negligible fraction (∼10%) was damaged during this process. This approach does not need any capturing or targeting of CTCs from the blood as it is focused on perturbing the electrical function of negatively-charged tumor cells after being exposed to positive electrostatic charges. Taken together, continuous in-vivo deactivation of CTCs by PPECS with no requirement to complicated capturing protocols may improve the survival of cancer patients.

Abstract
Introduction: The irreparable consequences of human error in the health care sector have made patient safety an important principle in medical professions. The aim of the present study was to investigate the probability of human error in operating room personnel in the process of appendectomy operations.
Materials and Methods: This cross-sectional and descriptive study was performed to identify and evaluate the probability of human error in operating room personnel's tasks in the process of appendectomy in Shahid Sadoughi Hospital in Yazd. Initially, by interviewing personnel and studying the process and procedures of the work, the job duties of the personnel were analyzed using HTA method. Finally, the probability of error was calculated using SPAR-H method for different tasks.
Results: The average human error probability for all tasks was 0.173. Also, the highest mean of error was related to anesthesiologist duties (0.23) and the least related to scrub duties (0.101).
Conclusion: The SPAR-H method can be used to analyze and quantify the probability of human error in the operating room. To reduce the likelihood of human error, we can reduce dependency by performing different tasks with different people and if possible with long time between them. Also, stress, complexity and procedures were identified as the most important factors affecting the probability of error.

Abstract
INTRODUCTION We examine the influence of variations in provision of cardiac surgery in the UK at hospital level on patient outcomes and also to assess whether there is an inequality of access and delivery of healthcare. Cardiothoracic surgery has pioneered the reporting of surgeon-specific outcomes, which other specialties have followed. We set out to identify factors other than the individual surgeon, which can affect outcomes and enable other surgical specialties to adopt a similar model. MATERIALS AND METHODS A retrospective analysis of prospectively collected data of patient and hospital level factors between 2013 and 2016 from 16 cardiac surgical units in the UK were analysed through the Society for Cardiothoracic Surgery of Great Britain and Ireland and the Royal College of Surgeons Research Collaborative. Patient demographic data, risks factors, postoperative complications and in-hospital mortality, as well as hospital-level factors such as number of beds and operating theatres, were collected. Correlation between outcome measures was assessed using Pearson's correlation coefficient. Associations between hospital-level factors and outcomes were assessed using univariable and multivariable regression models. RESULTS Of 50,871 patients (60.5% of UK caseload), 25% were older than 75 years and 29% were female. There was considerable variation between units in patient comorbidities, bed distribution and staffing. All hospitals had dedicated cardiothoracic intensive care beds and consultants. Median survival was 97.9% (range 96.3-98.6%). Postoperative complications included re-sternotomy for bleeding (median 4.8%; range 3.5-6.9%) and mediastinitis (0.4%; 0.1-1.0%), transient ischaemic attack/cerebrovascular accident (1.7%; range 0.3-3.0%), haemofiltration (3.7%; range 0.8-6.8%), intra-aortic balloon pump use (3.3%; range 0.4-7.4%), tracheostomy (1.6%; range 1.3-2.6%) and laparotomy (0.3%; range 0.2-0.6%). There was variation in outcomes between hospitals. Univariable analysis showed a small number of positive associations between hospital-level factors and outcomes but none remained significant in multivariable models. CONCLUSIONS Variations among hospital level factors exists in both delivery of, and outcomes, following cardiac surgery in the UK. However, there was no clear association between these factors and patient outcomes. This negative finding could be explained by differences in outcome definition, differences in risk factors between centres that are not captured by standard risk stratification scores or individual surgeon/team performance.

Abstract
The vasculature is essential for proper organ function. Many pathologies are directly and indirectly related to vascular dysfunction, which causes significant morbidity and mortality. A common pathophysiological feature of diseased vessels is extracellular matrix (ECM) remodelling. Analysing the protein composition of the ECM by conventional antibody-based techniques is challenging; alternative splicing or post-translational modifications, such as glycosylation, can mask epitopes required for antibody recognition. By contrast, proteomic analysis by mass spectrometry enables the study of proteins without the constraints of antibodies. Recent advances in proteomic techniques make it feasible to characterize the composition of the vascular ECM and its remodelling in disease. These developments may lead to the discovery of novel prognostic and diagnostic markers. Thus, proteomics holds potential for identifying ECM signatures to monitor vascular disease processes. Furthermore, a better understanding of the ECM remodelling processes in the vasculature might make ECM-associated proteins more attractive targets for drug discovery efforts. In this review, we will summarize the role of the ECM in the vasculature. Then, we will describe the challenges associated with studying the intricate network of ECM proteins and the current proteomic strategies to analyse the vascular ECM in metabolic and cardiovascular diseases.

Abstract
Immuno-inflammatory processes are implicated, as one of the prime pathogenic processes involved, in the development and progression of early atherosclerosis. High levels of circulating antiheat shock protein 60 (HSP60) autoantibodies have been associated with increasing severity of atherosclerosis in patients. We have recently presented evidence, extending this statistical association to that of causality, by showing that anti-HSP60 antibodies purified from sera of patients with documented atherosclerosis when injected into tail vein of apoE deficient mice resulted in accelerated atherosclerosis in them. High degree of sequence homology between microbial and mammalian HSP60, due to evolutionary conservation, carries a risk of misdirected autoimmunity against HSPs expressed on the stressed cells of vascular endothelium. HSPs and anti-HSP antibodies have been shown to elicit production of pro-inflammatory cytokines. These autoimmune reactions to HSPs expressed in the vascular tissue can contribute to both initiation and perpetuation of atherosclerosis.

Abstract
Background: Workers in wastewater treatment plants are exposed to a wide range of chemicals as well as biological contaminants. Objective: To ascertain whether exposure to bio-aerosols under the normal working conditions in wastewater treatment plants is associated with any significant changes in the prevalence of respiratory symptoms and lung function capacities. Methods: 198 employees of wastewater treatment plants and 99 unexposed persons were studied. American thoracic society (ATS) standard respiratory symptom questionnaire was used to determine the prevalence of respiratory symptoms. Pulmonary function tests were conducted for each participant. Results: The prevalence of respiratory symptoms among exposed persons was significantly higher than that of unexposed people. Mean values of most pulmonary function test parameters were significantly lower in the exposed compared to the comparison group persons. Conclusion: Increased prevalence of respiratory symptoms and decrements in pulmonary function test parameters may be attributed to exposure to bio-aerosols released from wastewater treatment plants.

Abstract
The shifting age demographic of the adult population has affected every area of contemporary medical and surgical practice. Many more people are living well, not just into their 70s but into their 80s and beyond. Their expectations of treatment for every illness have shifted markedly upwards at the same time. Despite the decline in cases of rheumatic fever in Westernised populations in recent times, the ageing population has led to no decline in the prevalence of valvular aortic stenosis. This is now realised to be an active pro-inflammatory disease, rather than a degenerative process. Thus the condition has remained in the mainstream and continues to be responsible for considerable morbidity, hospitalisation and mortality among the elderly and very elderly. Management has always been based on the triage of cases for direct intervention to the valve by surgery. Just as expectations have risen from patients, the techniques, application and monitoring of cardiac surgery have also made huge strides forward to meet this aspiration. More and more, surgeons are routinely asked to consider procedures in frailer, more elderly patients with more severe disease and co-morbidity. Managing the stenosis is rarely the only issue confronting the operating surgeon. Attempts to provide alternatives to open valve replacement surgery on cardiopulmonary bypass have now emerged. These are based around the transcutaneous placement of a valve prosthesis. While these technologies were initially highly selective in their application, they have now reached a stage to be compared with contemporary standards of cardiac surgical practice.

Abstract
A 27-year-old physical education teacher, from a rural sheep farming area of South Africa, was referred following an isolated episode of collapse. Transthoracic echocardiography and MRI showed a cystic lesion under the septal leaflet of the tricuspid valve attached to the right ventricular wall. A provisional diagnosis of hydatid cyst was made. Hydatid serology was negative and there was no evidence of hydatidosis elsewhere. Preoperatively, the patient was treated with praziquantel and albendazole. Surgery was performed using cardiopulmonary bypass. Cyst was excised without any spillage. The patient was weaned off bypass without any support and made an uneventful recovery. Cytology and microbiology of the specimen confirmed hydatid pathology. This case describes excision of a right ventricular hydatid with techniques used to avoid spillage. It also describes an up-to-date antihelminthic therapy used in the management of hydatid cysts.

Abstract
Accumulating evidence supports an autoimmune mechanism as one of the prime pathogenic processes involved in the development of atherosclerosis. So far, three proteins, including heat shock proteins (HSPs), oxidized low-density lipoprotein (oxLDL), and beta2 glycoprotein1 (beta2GP1) have been recognized as autoantigens. It has been demonstrated that risk factors for atherosclerosis, such as hypercholesterolemia, hypertension, infections, and oxidative stress, evoke increased expression of HSPs in cells of atherosclerotic lesions. Autoantibody levels against HSPs are significantly increased in patients with atherosclerosis and T lymphocytes specifically responding to these autoantigens have been demonstrated within atherosclerotic plaques. Subcutaneous immunization of animals with HSP65 induced atheroma formation in the arterial wall. Furthermore, circulating immunoglobulin (Ig) G and IgM oxidized low-density lipoprotein (oxLDL) antibodies are present in the plasma of animals and humans and form immune complexes with oxLDL in atherosclerotic lesions. These antibodies closely correlate with the progression and regression of atherosclerosis in murine models. Interestingly, recent reports demonstrated that pneumococcal vaccination to LDL receptor-deficient mice results in elevation of anti-oxLDL IgM Ab EO6, which is inversely correlated with the development of atherosclerosis. Finally, it has been observed that autoantigen beta2GP1 localizes in the atheroma and that autoantibodies to beta2GP1 are correlated with the incidence of atherosclerosis in patients. Hence, these autoimmune reactions to HSPs, oxLDL and beta2GP1 can contribute to the initiation and progression of atherosclerosis.

Abstract
OBJECTIVE To assess tricuspid valve function in atrioventricular discordance after palliative procedures (pulmonary artery banding and Blalock-Taussig shunt) and corrective procedures (anatomic and physiologic repair). METHODS Tricuspid valve dysfunction was assessed by transthoracic echocardiography and graded as no regurgitation (0), mild (1), moderate (2), and severe (3) before and after palliative and corrective procedures performed in 97 patients with atrioventricular discordance between 1988 and 1999. Thirty-two percent had an isolated ventricular septal defect, 43% had a ventricular septal defect and pulmonary stenosis, and 16% had pulmonary stenosis. Twenty-six patients underwent pulmonary artery banding and 28 had a Blalock-Taussig shunt. Seventy patients underwent physiologic and 19 underwent anatomic repair. Six patients underwent one-ventricle repair. RESULTS After pulmonary artery banding, the tricuspid regurgitation score decreased from 1.7 +/- 0.8 to 0.9 +/- 0.6 (P <.001). In patients who underwent a Blalock-Taussig shunt, the tricuspid regurgitation score increased from 0.7 +/- 0.5 preoperatively to 1.4 +/- 0.6 postoperatively (P <.001). After physiologic repair, there was no significant change in the tricuspid regurgitation score; however, 7 patients required additional repair or replacement. The regurgitation score was significantly reduced from 1.5 +/- 0.8 to 0.4 +/- 0.5 (P <.001) after anatomic repair. The operative mortality in patients who underwent physiologic repair was 7% as compared with 0% in the anatomic repair group (P =.59). The median follow-up was 3.2 years. CONCLUSIONS Right ventricular volume loading (shunt) worsens tricuspid regurgitation, whereas volume reduction (banding) or left-to-right septal shift (anatomic repair) has beneficial effects. We have not observed a significant change in the tricuspid regurgitation score after physiologic repair. Anatomic repair can be performed in selected patients with atrioventricular discordance and provides superior functional results.

Abstract
BACKGROUND We set out to examine the long-term results of relief of subaortic stenosis by enlargement of ventricular septal defect in patients with univentricular atrioventricular connection to a dominant left ventricle and discordant ventriculoarterial connections. METHODS Twenty-four patients underwent enlargement of ventricular septal defect between 1985 and 1998 at a median age of 3.2 years (range, 3 weeks to 14 years). Ten patients were younger than 1 year of age. Eighteen had undergone previous banding of the pulmonary trunk, 9 of whom also required repair of coarctation of the aorta. The median subaortic gradient before enlargement was 46 mm Hg. Twenty-three patients had a patch to enlarge the rudimentary right ventricle. RESULTS Five patients (21%) died in the early postoperative period. The overall survival at 1 and 3 years was 73%, and at 5 and 10 years was 68% and 60%, respectively. Complete heart block requiring insertion of a pacemaker occurred in 2 patients (8%). A Fontan operation was performed in 10 patients, 5 underwent a bidirectional Glenn procedure, and 2 required cardiac transplantation. Follow-up was complete in all survivors at a median time of 6.7 years (range, 8 months to 13 years). From the earlier part of the series, 3 patients experienced aortic insufficiency and 2 had recurrent obstruction. Factors adversely affecting survival were age younger than 1 year at operation and presence of obstruction within the aortic arch. CONCLUSIONS Our experience shows that, in patients with univentricular atrioventricular connection to a dominant left ventricle and subaortic stenosis, enlargement of the ventricular septal defect provides satisfactory relief of obstruction except in those younger than 1 year of age, and those who have associated obstruction in the aortic arch.

Abstract
OBJECTIVE Low-velocity and nonlaminar flow patterns in the Fontan circulation, as well as abnormal liver function in some patients, may partly account for the coagulation abnormalities seen. We examined (1) coagulation factor abnormalities before and after the Fontan procedure and (2) regional coagulation factor abnormalities in the Fontan circulation. METHODS Levels of factors V, VII, VIII, X, antithrombin III, prothrombin fragment F1+2, protein C, and protein S were measured in 2 groups of patients: In 14 patients undergoing the Fontan procedure, blood was analyzed before the operation and 5 days after the operation (group 1). The median age in this group was 3.2 years. In 10 patients who had undergone the Fontan procedure, cardiac catheterization was performed and samples were taken from the femoral vein, inferior vena cava, right atrium, and pulmonary artery (group 2). The median age in this group was 6.2 years and the median follow-up from the Fontan procedure was 4.1 years. RESULTS In group 1 a significant increase was noted postoperatively in the concentration of factor VIII (P<.001), factor X (P<.001), and prothrombin fraction F1+2 (P <.001). A significant decrease in the levels of antithrombin III (P <.001), protein C (P<.004), and protein S (P<.02) was also found. The increase in factors VIII and X persisted at 4 years' follow-up in group 2 patients. In group 2, no significant regional differences were observed between the coagulation factors measured at different sites. CONCLUSIONS There is an increased tendency toward coagulation after the Fontan procedure. A prothrombotic state is supported by thrombin generation associated with reduced antithrombin III concentration. This increase in coagulation may contribute to the early and late risks of thromboembolism observed after the Fontan procedure. We did not find any regional differences in coagulation abnormalities in patients late after the Fontan procedure. Therefore, the mechanisms and causes of the coagulation abnormalities remain unclear.

Abstract
OBJECTIVES We sought to assess the early and long-term results of subclavian flap angioplasty in neonates and infants, with particular attention to growth of the hypoplastic arch. METHODS A retrospective analysis of 185 consecutive patients who underwent subclavian flap angioplasty between 1974 and 1998 was carried out. The patients included 125 neonates and 60 infants, with a median age of 18 days. Sixty-six (36%) patients had an additional ventricular septal defect, 41 (22%) patients had aortic arch hypoplasia diagnosed preoperatively, 141 (76%) had an associated patent ductus arteriosus, and 41 (22%) had additional complex heart disease. Follow-up was with transthoracic Doppler echocardiography in all patients. RESULTS The early mortality was 3%. Recoarctation, defined as a Doppler gradient of 25 mm Hg or more, occurred in 11 (6%) patients at a median follow-up of 6.2 years (6.2 +/- 4.6 years). This included 4 of the 41 patients in whom arch hypoplasia was diagnosed preoperatively. There were no complications with the left arm. By multivariate analysis, risk factors for death were determined to be residual arch hypoplasia and low birth weight. The only risk factor for recoarctation was persistent arch hypoplasia after surgical treatment. However, angiographic imaging of the aorta showed that recoarctation was not due to a hypoplastic transverse arch, and it was probably at the site of ductal tissue. Survival at 5 and 10 years was 98% and 96%, respectively. Freedom from reoperation for recoarctation at 2 years was 95%, and at 5, 10, and 15 years, it was 92%. CONCLUSIONS Subclavian flap repair remains an effective technique for repair of aortic coarctation with excellent results and low mortality. In the majority of patients, arch hypoplasia regresses after this procedure.

Abstract
BACKGROUND Relief of primary or secondary subaortic stenosis (SAS) remains a surgical challenge. Heart block, aortic valve regurgitation and recurrent obstruction have been persistent problems. METHODS Forty six patients who underwent surgery for complex and tunnel-like SAS between January 1990 and November 1998 were reviewed. In 45 of the 46 patients SAS developed following repair of a primary congenital heart defect and only one patient presented with de novo tunnel-like SAS. Fifteen of the 45 patients had undergone repair of double-outlet right ventricle (DORV) and the remaining 30 had undergone repair of a variety of defects. The median age at the time of surgery was 5 years. The modified Konno procedure was performed in 15 patients, Konno procedure in three, Ross-Konno procedure in two and resection of the conal septum in 12 patients. Five patients with DORV underwent replacement of the intraventricular baffle and two patients underwent an aortic valve-preserving procedure in conjunction with mitral valve replacement. RESULTS There were no deaths. None of the patients had an exacerbation of aortic regurgitation and none developed complete heart block. The median follow-up was 3 years (range 1 month-8.5 years). Two patients developed recurrent SAS defined as a gradient of 40 mmHg or greater diagnosed by transthoracic echocardiography. Freedom from SAS at 1, 3 and 5 years was 100, 94 and 86%, respectively. CONCLUSIONS We favor the modified Konno procedure and conal resection to the Konno or the Ross procedure, since insertion of a prosthetic valve or homograft is avoided and aortic valve function is preserved. Excellent relief of tunnel-like SAS can be achieved without damage to the conduction tissue.

Abstract
OBJECTIVE Truncal valve regurgitation and interrupted aortic arch have frequently been identified as risk factors in the repair of truncus arteriosus. We wished to examine these factors in the current era including the impact of truncal valve repair. METHODS Between January 1992 and August 1998, 50 patients underwent surgical repair of truncus arteriosus. Their ages ranged from 2 days to 6 months (median, 2 weeks). Nine patients had associated interrupted aortic arch. Of the 14 patients (28%) in whom truncal valve regurgitation was diagnosed preoperatively, 5 had mild regurgitation, 5 had moderate regurgitation, and 4 had severe regurgitation. Five underwent truncal valve repair and 1 underwent homograft replacement of the truncal valve with coronary reimplantation. RESULTS The actuarial survival was 96% at 30 days, 1 year, and 3 years. There were no deaths in patients with associated interrupted aortic arch. The 2 deaths in the series occurred in patients with truncal valve regurgitation, neither of whom underwent repair. Postoperative transthoracic echocardiography in patients who underwent valve repair showed minimal residual valvular regurgitation. None of the patients has required reoperation because of truncal valve problems or aortic arch stenosis at a median follow-up of 23 months (range, 1-60 months). Conduit replacement has been done in 17 patients (34%) after a mean duration of 2 years. The freedom from reoperation for those who had an aortic homograft was 4 years and for those who had a pulmonary homograft was 3 years. CONCLUSION Despite the magnitude of the operation, excellent results can be achieved in complex forms of truncus arteriosus. In the current era interrupted aortic arch is no longer a risk factor for repair of truncus. Aggressive application of truncal valvuloplasty methods should neutralize the traditional risk factor of truncal valve regurgitation.

Abstract
OBJECTIVE Late outcome of neonatal pulmonary atresia with intact ventricular septum remains poor in most reported series. We have followed a selective approach toward either single ventricle repair versus complete or partial biventricular repair based on the presence of right ventricle-dependent coronary circulation and growth of the right ventricle. METHODS A retrospective chart review was conducted of 47 patients who underwent surgery between January 1991 and September 1998. RESULTS Sixteen (34%) patients had a right ventricle-dependent coronary circulation, with a tricuspid valve Z-score of -3.0 +/- 0.66 versus -2.0 +/- 0.95 (P =.002) for those without a right ventricle-dependent coronary circulation. A systemic-pulmonary artery shunt only was performed in all patients with a right ventricle-dependent coronary circulation, with 1 death. Fourteen of 16 patients with a right ventricle-dependent coronary circulation underwent a bidirectional Glenn shunt at a median of 9 months after their first operation, 9 of whom have had a Fontan procedure (no deaths). In the 31 (66%) patients without a right ventricle-dependent coronary circulation, 6 patients underwent only a systemic-pulmonary artery shunt, 23 had a shunt and right ventricular decompression, and 2 had only a transannular patch. In this group, 10 patients received a 2-ventricle repair, 6 a 1. 5-ventricle repair, and 8 patients had a Fontan procedure. There was 1 early death and the overall survival was 98% at 1 year, 5 years, and 7 years. CONCLUSIONS If patients are stratified well, excellent survival can be achieved in the treatment of pulmonary atresia with intact ventricular septum. This result may be at the price of achieving a 1-ventricle as opposed to a 2-ventricle repair.

Abstract
BACKGROUND Although some pediatric cardiology departments have a policy of adopting primary correction of tetralogy of Fallot in all symptomatic infants, we and others still palliate neonates and infants. Effective palliation should ameliorate symptoms and allow growth of the pulmonary arteries. Although studies on the growth of the ipsilateral and contralateral pulmonary arteries after a classic Blalock-Taussig shunt have been reported, pulmonary artery growth after a modified Blalock-Taussig shunt has not been studied as thoroughly. Therefore, we examined whether there is equal growth of the contralateral pulmonary artery after a modified Blalock-Taussig shunt. METHODS We retrospectively analyzed the records of 140 patients with symptomatic tetralogy of Fallot who had a modified Blalock-Taussig shunt between October 1985 and October 1995. The median age at the time of the Blalock-Taussig shunt was 1.6 months. All patients had corrective procedures at a median age of 1.7 years. Cineangiography was done before the corrective procedure. From the angiograms the diameter of the right and left pulmonary arteries before their first lobar branches and the diameter of the descending thoracic aorta at the level of the diaphragm were measured. For each patient the ratios of right pulmonary artery to descending thoracic aorta and left pulmonary artery to descending thoracic aorta were determined and compared using Student's t test. RESULTS Of the 140 patients, 114 had a left-sided Blalock-Taussig shunt, 20 had a right-sided shunt, and 6 patients had bilateral shunts. The mean right pulmonary artery to descending thoracic aorta ratio was 1.10 and the mean left pulmonary artery to descending thoracic aorta ratio was 0.98. This difference was not significant. CONCLUSION We showed equal growth of the right and left pulmonary arteries with no distortion after a modified Blalock-Taussig shunt. If palliation is considered, the modified Blalock-Taussig shunt remains our choice.

Abstract
BACKGROUND Increasing evidence shows that thrombogenicity and atherogenicity of lipoproteins are related to modifications involving oxidative, enzymatic, or physical alterations of these molecules. Findings on lipid peroxidation associated with cardiopulmonary bypass are conflicting, and the possible other forms of atherogenic lipid modification are unknown. The various forms of lipoprotein modifications including lipid peroxidation, desialylation, and leukocytic elastase activity after coronary artery bypass graft operations are examined. METHODS In patients undergoing coronary artery bypass graft operations, plasma total lipid hydroperoxides (n = 102), plasma leukocytic elastase activity (n = 125), free radical formation (n = 30), low-density lipoprotein oxidation, and sialic acid content before operation and at 2, 24, 48, and 72 hours after cardiopulmonary bypass and 3 months after operation were measured. RESULTS Preoperative plasma lipid peroxide concentration (2.2 micromol/L) increased after cardiopulmonary bypass (peak, 7.5 micromol/L; p<0.001) and remained significantly elevated at 3 months after surgery (4.2 micromol/L; p<0.01). There was a significant correlation between increased free radical generation and lipid peroxide levels in blood at all postoperative intervals. Low-density lipoprotein separated from plasma samples showed increased oxidation 48 hours after bypass. Sialic acid content of low-density lipoprotein was significantly reduced 48 hours after bypass. Plasma elastase activity increased significantly at all postoperative intervals. CONCLUSIONS Coronary artery bypass graft operation is associated with generation of sustained blood levels of modified lipoproteins. These thrombogenic and atherogenic particles may play an important role in hemostatic and arteriosclerotic complications of coronary artery bypass graft operations.

Abstract
Respiratory compromise secondary to external vascular compression may complicate the course of infants and neonates undergoing repair of congeni tal heart disease. Management of such complications usually involves prolonged ventilatory support and even additional high-risk surgical procedures. In recent years, endobronchial placement of self-expanding stents became a realistic treatment option, although there is controversy as to which of the many stents available today give the best results. We report the first successful endobronchial placement of a self-expanding stent in a 4-week-old infant. This conservative treatment for extrinsic airway compression led to the rapid extubation and recovery of the patient.

Abstract
The early detection of breast cancer increases the survival rate in women. Today, film-screen mammography is the most common and effective technique for the detection of breast cancer. However, the film-screen image recording system of current mammography has several technical limitations that can reduce the breast cancer diagnostic accuracy. A state-of-the-art technology, full-field direct digital mammography (FFDDM) has the potential to increase the sensitivity of clinical and screening examinations and emerge as a film-screen mammography replacement. It is believed that efficiently delivering the superior image quality of FFDDM to expert mammographers will significantly increase the breast cancer diagnostic accuracy. This concept motivates the studies of FFDDM telemammography. In this paper, we will report the FFDDM telemammography project that is being conducted in our facility. The fundamental technology of the FFDDM system and the characteristics of FFDDM images are described. Our research approach is through three protocols: telediagnosis, teleconsultation, and telemanagement. Each of these study protocols is defined. To conduct this FFDDM telemammography project, an asynchronous transfer-mode-network-based telemammography system is developed across two remote campuses in our facility. The architecture of this system is detailed. Unlike other medical imaging modalities, the matrix of an FFDDM image is huge. How to present the image information to mammographers via currently available display media is a challenging task. Our display approaches for the FFDDM images are described. Some preliminary study results from the current phase of this study are reported.

Abstract
OBJECTIVE To examine the short term results and long term survival of patients on long term dialysis undergoing coronary artery bypass graft surgery. METHODS A retrospective analysis of 19 patients on established dialysis who underwent coronary revascularisation between 1983 and 1995; 14 patients (73%) had class IV angina and five (25%) had unstable angina requiring heparin and nitrate infusions before surgery. RESULTS The 30 day mortality was 5%. Follow up was completed in the remaining 18 patients. The mean follow up time was 34 months (range eight to 61). During the follow up period four patients died of cardiac causes. The actuarial survival at one, two, and three years was 87%, 78%, and 59%, respectively. The overall functional status was significantly improved compared to preoperative levels, with a mean Karnofsky score of 76% (p < 0.01) at three years. CONCLUSIONS Coronary artery bypass graft surgery can be performed with increased but acceptable morbidity and mortality in chronic dialysis patients. It results in considerable improvement in symptoms and functional status. However, long term survival is limited and this requires further investigation.
