Abstract
Background: Patients with rheumatic heart disease with atrial fibrillation incur significant morbidity and mortality. Which approach, ventricular rate control or maintenance of sinus rhythm, in this setting might be superior is not known. The role of amiodarone in this patient population for maintaining sinus rhythm has not been evaluated. Methods and Results: We prospectively studied 144 patients with chronic rheumatic atrial fibrillation in a double-blind protocol in which rhythm control (group I), comprising 48 patients each with amiodarone (group Ia) and placebo (group Ib), were compared with each other and with patients in a ventricular rate control group (group II) in which the effects by diltiazem were determined (n = 48, open-label). Direct current cardioversion was attempted in group I. The mean age of the study population was 38.6 ± 10.3 years, left atrial size, 4.7 ±0.6 cm; atrial fibrillation duration, 6.1 ± 5.4 years; and 72.9% had valvular interventions performed. At 1 year, 45 patients with sinus rhythm in group I compared with 48 in group II demonstrated an increase in exercise time (2.6 ± 1.9 vs. 0.6 ± 2.5 min, P = .001), improvement in New York Heart Association class of 1 or more ( P = .002), and improvement in the quality-of-life score of one or greater ( P = 0.01) with no difference in hospitalizations, systemic bleeds, or thromboembolism. Five patients died in group II; none died in group I ( P =.02). In group I, 73 of 87 (83.9%) patients converted to sinus rhythm and 45 of 86 (52.3%) patients maintained the rhythm at 1 year. Conversion rates were 38 of 43 (88.4%) with amiodarone versus 34 of 44 (77.3%) with placebo ( P = .49); the corresponding rate for maintaining sinus rhythm was 29 of 42 (69.1%) versus 16 of 44 (36.4%) ( P = .008). A larger number of electrical cardioversions were required in the placebo group (2.1 vs. 1.4, P = .011). Conclusions: Maintenance of sinus rhythm is superior to ventricular rate control in patients with rheumatic atrial fibrillation with respect to effects on exercise capacity, quality of life, morbidity, and possibly mortality. Sinus rhythm could be restored in most patients, and amiodarone was superior to placebo in the restoration and maintenance of sinus rhythm.

Abstract
INTRODUCTION Since the establishment of the Uganda Rheumatic Heart Registry, over 900 patients have been enrolled. We sought to stratify the patients in the registry according to disease severity and optimal management strategy. METHODS We reviewed data of 618 patients who had enrolled in the Registry between March 2010 and February 2013. The 67 patients who had died were excluded leaving 551 patients who were recruited. The optimum management strategy was determined according to the 2012 European Society of Cardiology guidelines on the management of valvular heart disease. RESULTS Out of the 551 patient's records evaluated, 398 (72.3%) required invasive intervention, with 332(60.3%) patients requiring surgery and 66 (12.0%) requiring percutaneous mitral commissurotomy (PMC). This leaves only 27.7% of patients who required only medical management. Currently, majority of the patients (498, 90.4%) in the registry are on medical treatment. Of the 60.3% requiring surgical intervention, only 8.0% (44 patients) underwent valvular surgery and 5(1.0%) patients of the 66 (12.0%) underwent PMC successfully. CONCLUSION There is a high proportion of patients with severe disease that require surgical treatment yet they cannot access this therapy due to absence of local expertise.

Abstract
BACKGROUND Rheumatic heart disease remains an important cause of acquired heart disease in developing countries. Although prevention of rheumatic fever and management of recurrences have been well established, optimal management of active rheumatic carditis remains unclear. This is an update of a review published in 2003, and previously updated in 2009 and 2012. OBJECTIVES To assess the effects, both harmful and beneficial, of anti-inflammatory agents such as aspirin, corticosteroids and other drugs in preventing or reducing further valvular damage in patients with acute rheumatic fever. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (2013, Issue 9 of 12), MEDLINE (Ovid, 1948 to 2013 October Week 1), EMBASE (Ovid, 1980 to 2013 Week 41) and Latin American Caribbean Health Sciences Literature (LILACS) (1982 to 17 October 2013). We last searched Index Medicus (1950 to April 2001) in 2001. We checked reference lists of identified studies and applied no language restrictions. SELECTION CRITERIA Randomised controlled trials comparing anti-inflammatory agents (e.g. aspirin, steroids, immunoglobulins, pentoxifylline) versus placebo or controls, or comparing any of the anti-inflammatory agents versus one another, in adults and children with acute rheumatic fever diagnosed according to Jones, or modified Jones, criteria. The presence of cardiac disease one year after treatment was the major outcome criterion selected. DATA COLLECTION AND ANALYSIS Two review authors extracted data and assessed risk of bias using the methodology outlined in the Cochrane Handbook of Systematic Reviews of Interventions. Standard methodological procedures as expected by The Cochrane Collaboration were used. MAIN RESULTS No new studies were included in this update. Eight randomised controlled trials involving 996 people were selected for inclusion in the review. Researchers compared several steroidal agents such as corticotrophin, cortisone, hydrocortisone, dexamethasone, prednisone and intravenous immunoglobulin versus aspirin, placebo or no treatment. Six trials were conducted between 1950 and 1965; one was done in 1990 and the final study was published in 2001. Overall there were no observed significant differences in risk of cardiac disease at one year between corticosteroid-treated and aspirin-treated groups (six studies, 907 participants, risk ratio 0.87, 95% confidence interval 0.66 to 1.15). Similarly, use of prednisone (two studies, 212 participants, risk ratio 1.13, 95% confidence interval 0.52 to 2.45) compared with aspirin did not reduce the risk of heart disease after one year. Investigators in five studies did not report adverse events. The three studies reporting on adverse events reported substantial adverse events. However, all results should be interpreted with caution because of the age of the studies and the substantial risk of bias. AUTHORS' CONCLUSIONS Little evidence of benefit was found when corticosteroids or intravenous immunoglobulins were used to reduce the risk of heart valve lesions in patients with acute rheumatic fever. The antiquity of most of the trials restricted adequate statistical analysis of the data and acceptable assessment of clinical outcomes by current standards. In addition, risk of bias was substantial, so results should be viewed with caution. New randomised controlled trials in patients with acute rheumatic fever are warranted to assess the effects of corticosteroids such as oral prednisone and intravenous methylprednisolone and the effects of other new anti-inflammatory agents. Advances in echocardiography will allow more objective and precise assessments of cardiac outcomes.

Abstract
OBJECTIVE To observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB). METHODS Totally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished. RESULTS There was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05). CONCLUSION LH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.

Abstract
BACKGROUND Rheumatic heart disease (RHD) remains an important health issue for indigenous women of child-bearing age in northern Australia. However, the influence of RHD on maternal outcomes with current clinical practice is unclear. AIMS To determine maternal cardiac complications and obstetric outcomes in patients with RHD. METHODS Retrospective case note analysis of women with RHD who received obstetric care between July 1999 and May 2010 at Cairns Base Hospital in north Queensland. Outcome measures were obstetric interventions and outcomes, cardiac interventions and complications, stratified according to a cardiac risk score (CRS). RESULTS Ninety-five confinements occurred in 54 patients, of whom 52 were Indigenous Australians. There were no maternal or neonatal deaths. With a CRS of 0, cardiac complications occurred in 0 of 70 confinements; with a CRS of 1, complications occurred in 5 of 17 confinements (29%); with a CRS of >1, complications occurred in 2 of 4 confinements (50%). Another four patients were first diagnosed with RHD after developing acute pulmonary oedema during the peripartum period. CONCLUSIONS RHD has a major impact on maternal cardiac outcomes. However, with current management practices, maternal and fetal mortality are low, and the incidence of complications is predictable based on known risk factors.

Abstract
BACKGROUND Rheumatic heart disease (RHD) remains a major health concern for Aboriginal Australians. A key component of RHD control is prevention of recurrent acute rheumatic fever (ARF) using long-term secondary prophylaxis with intramuscular benzathine penicillin (BPG). This is the most important and cost-effective step in RHD control. However, there are significant challenges to effective implementation of secondary prophylaxis programs. This project aimed to increase understanding and improve quality of RHD care through development and implementation of a continuous quality improvement (CQI) strategy. METHODS We used a CQI strategy to promote implementation of national best-practice ARF/RHD management guidelines at primary health care level in Indigenous communities of the Northern Territory (NT), Australia, 2008-2010. Participatory action research methods were employed to identify system barriers to delivery of high quality care. This entailed facilitated discussion with primary care staff aided by a system assessment tool (SAT). Participants were encouraged to develop and implement strategies to overcome identified barriers, including better record-keeping, triage systems and strategies for patient follow-up. To assess performance, clinical records were audited at baseline, then annually for two years. Key performance indicators included proportion of people receiving adequate secondary prophylaxis (≥80% of scheduled 4-weekly penicillin injections) and quality of documentation. RESULTS Six health centres participated, servicing approximately 154 people with ARF/RHD. Improvements occurred in indicators of service delivery including proportion of people receiving ≥40% of their scheduled BPG (increasing from 81/116 [70%] at baseline to 84/103 [82%] in year three, p = 0.04), proportion of people reviewed by a doctor within the past two years (112/154 [73%] and 134/156 [86%], p = 0.003), and proportion of people who received influenza vaccination (57/154 [37%] to 86/156 [55%], p = 0.001). However, the proportion receiving ≥80% of scheduled BPG did not change. Documentation in medical files improved: ARF episode documentation increased from 31/55 (56%) to 50/62 (81%) (p = 0.004), and RHD risk category documentation from 87/154 (56%) to 103/145 (76%) (p < 0.001). Large differences in performance were noted between health centres, reflected to some extent in SAT scores. CONCLUSIONS A CQI process using a systems approach and participatory action research methodology can significantly improve delivery of ARF/RHD care.

Abstract
AIM The aim of this programme was to find undetected rheumatic heart disease (RHD) in students from selected schools in the Tairawhiti region (eastern part of the North Island) of New Zealand. METHOD Portable echocardiography was used to scan students in 5 urban and rural schools in Tairawhiti where the population is predominantly Maori. The age range of students in the urban schools was 10-13 years and in the rural schools 5-17 years. Those with abnormal echocardiograms were referred for a paediatric consultation, with hospital-based echocardiography if required for the clarification of diagnoses and further management. RESULTS A total of 685 students, representing over 95% of the schools' students, consented to having echocardiographic scanning. After repeat hospital based echocardiography for 11 students, a total of 52 scans were regarded as abnormal. In this population definite (n=4) or probable (n=7) RHD was found in 11 students a prevalence of 1.61% (95%CIs 0.80-2.85). Possible RHD was found in 19 students. Previously undetected confirmed (n=1) or probable (n=7) RHD was found in 8 students a prevalence of 1.17% (95%CIs 0.51-2.29). Congenital heart defects (CHD) were found in 22 students a prevalence of 3.21% (95%CIs 2.02-4.83). CONCLUSION Echocardiography was a popular modality and detected a significant burden of previously unknown RHD in this young Maori population who are now receiving penicillin. However, echocardiography detected a greater prevalence of possible RHD for which optimum management is at present uncertain. Echocardiography also detected students with a range of severity of CHD. Screening with echocardiography for RHD would involve a significant use of public health, paediatric and cardiac resources with 7.6% of students and their families requiring clinical consultations and ongoing management of the abnormal echocardiographic results.

Abstract
BACKGROUND Historically, sub-Saharan Africa has had the highest prevalence rates of clinically detected rheumatic heart disease (RHD). Echocardiography-based screening improves detection of RHD in endemic regions. The newest screening guidelines (2006 World Health Organization/National Institutes of Health) have been tested across India and the Pacific Islands, but application in sub-Saharan Africa has, thus far, been limited to Mozambique. We used these guidelines to determine RHD prevalence in a large cohort of Ugandan school children, to identify risk factors for occult disease, and to assess the value of laboratory testing. METHODS AND RESULTS Auscultation and portable echocardiography were used to screen randomly selected schoolchildren, 5 to 16 years of age, in Kampala, Uganda. Disease likelihood was defined as definite, probable, or possible in accordance with the 2006 National Institutes of Health/World Health Organization guidelines. Ninety-seven percent of eligible students received screening (4869 of 5006). Among them, 130 children (2.7%) had abnormal screening echocardiograms. Of those 130, secondary evaluation showed 72 (55.4%) with possible, probable, or definite RHD; 18 (13.8%) with congenital heart disease; and 40 (30.8%) with no disease. Echocardiography detected 3 times as many cases of RHD as auscultation: 72 (1.5%) versus 23 (0.5%; P<0.001). Children with RHD were older (10.1 versus 9.3 years; P=0.002). Most cases (98%) involved only the mitral valve. Lower socioeconomic groups had more RHD (2.7% versus 1.4%; P=0.036) and more advanced disease (64% versus 26%; P<0.001). Antistreptolysin O titers were elevated in children with definite RHD. CONCLUSIONS This is one of the largest single-country childhood RHD prevalence studies and the first to be conducted in sub-Saharan Africa. Our data support inclusion of echocardiography in screening protocols, even in the most resource-constrained settings, and identify lower socioeconomic groups as most vulnerable. Longitudinal follow-up of children with echocardiographically diagnosed subclinical RHD is needed.

Abstract
BACKGROUND Antithrombotic therapy in valvular disease is important to mitigate thromboembolism, but the hemorrhagic risk imposed must be considered. METHODS The methods of this guideline follow those described in Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines. Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines in this supplement. RESULTS In rheumatic mitral disease, we recommend vitamin K antagonist (VKA) therapy when the left atrial diameter is > 55 mm (Grade 2C) or when complicated by left atrial thrombus (Grade 1A). In candidates for percutaneous mitral valvotomy with left atrial thrombus, we recommend VKA therapy until thrombus resolution, and we recommend abandoning valvotomy if the thrombus fails to resolve (Grade 1A). In patients with patent foramen ovale (PFO) and stroke or transient ischemic attack, we recommend initial aspirin therapy (Grade 1B) and suggest substitution of VKA if recurrence (Grade 2C). In patients with cryptogenic stroke and DVT and a PFO, we recommend VKA therapy for 3 months (Grade 1B) and consideration of PFO closure (Grade 2C). We recommend against the use of anticoagulant (Grade 1C) and antiplatelet therapy (Grade 1B) for native valve endocarditis. We suggest holding VKA therapy until the patient is stabilized without neurologic complications for infective endocarditis of a prosthetic valve (Grade 2C). In the first 3 months after bioprosthetic valve implantation, we recommend aspirin for aortic valves (Grade 2C), the addition of clopidogrel to aspirin if the aortic valve is transcatheter (Grade 2C), and VKA therapy with a target international normalized ratio (INR) of 2.5 for mitral valves (Grade 2C). After 3 months, we suggest aspirin therapy (Grade 2C). We recommend early bridging of mechanical valve patients to VKA therapy with unfractionated heparin (DVT dosing) or low-molecular-weight heparin (Grade 2C). We recommend long-term VKA therapy for all mechanical valves (Grade 1B): target INR 2.5 for aortic (Grade 1B) and 3.0 for mitral or double valve (Grade 2C). In patients with mechanical valves at low bleeding risk, we suggest the addition of low-dose aspirin (50-100 mg/d) (Grade 1B). In valve repair patients, we suggest aspirin therapy (Grade 2C). In patients with thrombosed prosthetic valve, we recommend fibrinolysis for right-sided valves and left-sided valves with thrombus area < 0.8 cm(2) (Grade 2C). For patients with left-sided prosthetic valve thrombosis and thrombus area ≥ 0.8 cm(2), we recommend early surgery (Grade 2C). CONCLUSIONS These antithrombotic guidelines provide recommendations based on the optimal balance of thrombotic and hemorrhagic risk.

Abstract
A 62-year-old woman presented to a primary care doctor on January 2006 due to a sore throat and high fever, and had received medication for a common cold. She was referred to our hospital in February 2006 because of additional manifestations such as painful rashes on the lower limb similar to erythema nodosum and polyarthralgia on her feet, shoulder and finger joints. She was initially treated with an anti-inflammatory drug (NSAID) for polyarthritis but the symptoms did not improved. In addition, the serum level of anti-streptolysin O antibody (ASO) was elevated at the second visit more than that at the first visit. She was diagnosed to have rheumatic fever (RF) based on the polyarthritis, inflammatory data and an increase of the ASO level. She was treated with 10 mg a day of prednisolone (PSL) and sultamicillin tosilate. However, a systolic murmur that had been never noticed by previous auscultation appeared after the third hospital day and the mitral regurgitation was also detected on echocardiogram. She was then treated with 40 mg a day of PSL because of an appearance of the carditis due to RF. The increased PSL dose promptly improved the systolic murmur as well as the arthritis. This report presented an RF case with carditis detected by an development of the systolic murmur in an adult female.

Abstract
The evaluation of valvular and nonvalvular structures is of central importance in the diagnosis, management, and treatment of infective endocarditis (IE). The incidence of IE has remained constant due to changing substrate, with notably higher prevalence observed in the elderly. Mortality and morbidity continue to remain high, despite advances in medical and surgical treatment. This article reviews the technical and practical aspects of the use of echocardiography to evaluate patients with suspected IE.

Abstract
Iatrogeny is a pathologic condition caused in a patient in the different stages of a medical act. In the United States, it is the fourth cause of death but in Portugal, data are not yet available. Though different from medical error, it is still a taboo subject for health care providers. The authors report a case of relational, diagnostic and therapeutic iatrogeny with serious consequences for the patient. Doctors have a fundamental role in reducing morbidity and mortality due to iatrogenic causes; they have the duty to question and reconsider diagnosis and treatments, keeping an alert attitude and self-criticism in order to identify potential iatrogenic interventions or to correct it as soon as possible.

Abstract
In this article the authors describe a clinical case of acute rheumatic fever (according to revised Jones criteria, American Heart Association [AHA], 1992) with cardiac tamponade, emphasizing this uncommon presentation. An adolescent patient with a clinical picture of cardiac tamponade was seen in the emergency department. Clinical progression and tests demonstrated rheumatic carditis with an initial manifestation of pericarditis with cardiac tamponade. This report aims to warn physicians about the diagnosis of rheumatic carditis in an unusual clinical presentation, in cases of cardiac tamponade, particularly in school-aged children and adolescents in countries with a high prevalence of rheumatic fever. The literature contains only two documented cases of cardiac tamponade related to acute rheumatic fever, and this case represents a third.

Abstract
OBJECTIVE To compare the efficacy of combined amiodarone and irbesartan use versus amiodarone alone on maintaining sinus rhythm in rheumatic heart disease patients with persistent atrial fibrillation (AF) post valve replacement and cardioversion. METHODS Patients were randomly divided into amiodarone group (A, n = 31) and amiodarone plus irbesartan group (AI, n = 32) and all patients received Warfarin (INR 2.0 - 3.0). For patients in group A, intravenous amiodarone (600 mg/d) was applied for 10 days and oral amiodarone (200 mg, b.i.d.) was given on the 7th day for 3 days. For patients in group AI, irbesartan (150 mg/d) was added on top of amiodarone at the study begin. Electric cardioversion was performed for patients still with AF on day 10. Amiodarone (200 mg, b.i.d. for 1 week, then 200 mg, q.d. till study end) with or without irbesartan (150 mg/d) was continued thereafter. Patients were followed up for 12 months after sinus rhythm recovery. The primary end points are first recurrence of symptomatic and asymptomatic AF. RESULTS Twelve months post therapy, number of patients on sinus rhythm was significantly higher (68.7% vs. 41.9%, P<0.05) and left atrium diameter (LAD) was significantly smaller [(48.6 +/- 4.6) mm vs. (51.5 +/- 4.2) mm, P<0.05] in group AI than those in group A. LAD (OR 1.242) and use of irbesartan (OR 0.226) are associated with the AF recurrence. CONCLUSION Combined amiodarone and irbesartan use is superior to amiodarone alone for maintaining sinus rhythm in rheumatic heart disease patients with persistent AF post valve replacement and cardioversion.

Abstract
Primary prevention of acute rheumatic fever is accomplished by proper identification and adequate antibiotic treatment of group A beta-hemolytic streptococcal (GAS) tonsillopharyngitis. Diagnosis of GAS pharyngitis is best accomplished by combining clinical judgment with diagnostic test results, the criterion standard of which is the throat culture. Penicillin (either oral penicillin V or injectable benzathine penicillin) is the treatment of choice, because it is cost-effective, has a narrow spectrum of activity, and has long-standing proven efficacy, and GAS resistant to penicillin have not been documented. For penicillin-allergic individuals, acceptable alternatives include a narrow-spectrum oral cephalosporin, oral clindamycin, or various oral macrolides or azalides. The individual who has had an attack of rheumatic fever is at very high risk of developing recurrences after subsequent GAS pharyngitis and needs continuous antimicrobial prophylaxis to prevent such recurrences (secondary prevention). The recommended duration of prophylaxis depends on the number of previous attacks, the time elapsed since the last attack, the risk of exposure to GAS infections, the age of the patient, and the presence or absence of cardiac involvement. Penicillin is again the agent of choice for secondary prophylaxis, but sulfadiazine or a macrolide or azalide are acceptable alternatives in penicillin-allergic individuals. This report updates the 1995 statement by the American Heart Association Rheumatic Fever, Endocarditis, and Kawasaki Disease Committee. It includes new recommendations for the diagnosis and treatment of GAS pharyngitis, as well as for the secondary prevention of rheumatic fever, and classifies the strength of the recommendations and level of evidence supporting them.

Abstract
JUSTIFICATION Acute rheumatic fever and rheumatic chronic valvular heart disease is an important preventable cause of morbidity and mortality in suburban and rural India. Its diagnosis is based on clinical criteria. These criteria need verification and revision in the Indian context. Furthermore, there are glaring differences in management protocols available in literature. These facts prompted Indian Academy of Pediatrics to review the management of rheumatic fever. PROCESS Management of Rheumatic fever was reviewed and recommendation was formulated at national consultative meeting on 20th May 2007 at New Delhi. OBJECTIVES To formulate uniform guidelines on management of acute rheumatic fever and rheumatic heart disease in the Indian context. Guidelines were formulated for the management of streptococcal pharyngitis, acute rheumatic fever and its cardiac complication as well as secondary prophylaxis for recurrent episodes. RECOMMENDATIONS (1) Streptococcal eradication with appropriate antibiotics (Benzathine penicillin single dose or penicillin V oral or azithromycin). (2) Diagnosis of rheumatic fever based on Jones criteria. (3) Control inflammatory process with aspirin with or without steroids (total duration of treatment of 12 weeks). (4) Treatment of chorea according to severity (therapy to continue for 2-3 weeks after clinical improvement). (5) Protocol for managing cardiac complication like valvular heart disease, congestive heart failure and atrial fibrillation. (6) Secondary prophylaxis with benzathine penicillin and management of anaphylaxis.

Abstract
AIM The National Heart Foundation of New Zealand, and the Cardiac Society of Australia and New Zealand (CSANZ) recently launched an evidence-based review and guideline entitled New Zealand Guideline for Rheumatic Fever Diagnosis, Management, and Secondary Prevention. This paper is a brief summary. METHOD This Guideline was developed by a writing group comprising experts in the area. Relevant literature was identified and reviewed, and the Australian guideline for rheumatic fever and rheumatic heart disease was reviewed and adapted for the New Zealand context. A peer review and stakeholder consultation process followed the development of the draft document. RESULTS The final draft of the New Zealand guideline was endorsed by Te Hotu Manawa Maori, Pacific Islands Heart Beat, The Paediatric Society of New Zealand, and the Rheumatic Fever Trust of New Zealand--plus approved by a number of organisations including the Royal Australasian College of Physicians, the Australasian Society for Infectious Disease, the Pasifika Medical Association, and Te Ohu Rata o Aotearoa. Two subsequent New Zealand guidelines for rheumatic fever: Sore Throat Management and Primary Prevention are also in production. The complete guideline, and associated summary algorithms, can be downloaded from www.nhf.org.nz CONCLUSION A New Zealand Guideline for Rheumatic Fever Diagnosis, Management and Secondary Prevention of Acute Rheumatic Fever should result in improved consistency in the approach to this disease, and reduced mortality and morbidity from acute rheumatic fever and rheumatic heart disease.

Abstract
We studied inotropic reaction of isolated myocardium of patients with heart failure induced by ischemic and rheumatic cardiac involvement after periods of rest at the background of amiodarone. The studies were carried out on muscular trabeculi separated from right atrial auricle during surgery. It was shown that inotropic reaction of insufficient myocardium could be of 2 types. In type I inotropic reaction first contraction after period of rest either exceeded basal contractions or remained at their level. Type 2 was characterized by significant lowering of amplitude of contractions relative to regular ones. Exposure of the myocardium to amiodarone (1 micro/L) led to significant potentiation of trabeculi contraction after periods of rest of muscles with type I reaction and did not affect response of muscles with type II reaction. These results allow to conclude that the state of calcium transporting systems of sarcoplasmic reticulum (SR) is different in ischemic and rheumatic heart failure and that realization of therapeutic effect of amiodarone depends on functional state of SR.

Abstract
OBJECTIVE To investigate the effects of cattle encephalon glycoside and ignotin injection on serum level of S100B protein and neuron specific enolase (NSE) during cardiac valve replacement with cardiopulmonary bypass (CPB). METHODS Forty patients undergoing cardiac valve replacement with CPB were randomly divided into two equal groups: cattle encephalon glycoside and ignotin injection group (Group A, injected intravenously with cattle encephalon glycoside and ignotin 20 ml after induction of anesthesia, and control group (Group B, injected intravenously with normal saline instead. Blood samples were taken from the jugular bulb after induction of anesthesia (T1), immediately, and 2 h, 6 h, and 24 h after the discontinuation of CPB (T2, T3, T4, and T5) for determination of serum levels of S100B protein and NSE. RESULTS The serum levels of S100B protein and NSE of both groups were significantly increased after CPB, and then gradually decreased. At the time point T5, the serum levels of S100B protein of both groups decreased to near the baseline levels (T1 levels), but the serum levels of NSE remained high in both groups. At the time points T2, T3, T4 and T5, the serum levels of S100B protein were significantly higher in Group B than in Group A (all P < 0.05). At the time points T2, T3, and T4, the serum levels of NSE was significantly higher in Group B than in Group A (all P < 0.05). CONCLUSION Cattle encephalon glycoside and ignotin injection decreases the serum levels of S100B protein and NSE and has cerebral protective effect during cardiac valve replacement with CPB to a certain degree.

Abstract
Ischemic stroke secondary to cardiac disease accounts for approximately 30% of all stroke subtypes and it may be due to a large list of conditions. Stroke secondary to heart disease causes more severe deficits, higher mortality, and increased costs that other stroke subtypes. Therefore, proper identification of cardioembolic stroke is crucial for adequate selection of optimal preventive strategies. Identification of stroke prone individuals with heart disease could also have an important therapeutic impact. This manuscript reviews the interaction between the heart and brain with a particularly emphasis in the current state of older and newer antithrombotic drugs for stroke prevention in patients with atrial fibrillation. Other neuro-cardiological issues reviewed include current antithrombotic strategies in patients with a host of heart conditions which include pacemakers, acute myocardial infarction, congestive heart failure, cardiac procedures, patent foramen ovale, valve disease, endocarditis, or cardiac tumours.
