Abstract
BACKGROUND AND AIM OF THE STUDY Rheumatic fever is still the main cause of valve disease in developing countries. The study aim was to investigate the appropriateness of mitral valve repair in adult patients with rheumatic heart disease (RHD). METHODS A systematic literature retrieval was performed for all clinical trials comparing the outcomes of mitral valve repair and replacement for RHD in PubMed, EMBASE and the Cochrane Library. Studies were excluded if they lacked a direct comparison of repair versus replacement. The primary outcomes were 30-day and long-term (> 5 years) survival. Secondary outcomes were postoperative complications and reoperation rates. Standard meta-analysis techniques were used. RESULTS A total of seven studies was included. When comparing mitral valve repair (MVP) to mitral valve replacement (MVR), the summary odds ratio for 30-day mortality was 0.54 (95% confidence interval (CI) 0.34-0.86; p = 0.009), and the summary hazard ratio (HR) for long-term mortality was 0.62 (95% CI 0.45-0.85; p = 0.003). Other than the benefits of better survival rates, the risk of postoperative complications (cardiac death, bleeding or thromboembolic complications) was also lower in the repair group (HR 0.63; 95% CI 0.47-0.84; p = 0.002). A significantly higher reoperation rate was observed among patients with mitral valve repair (HR 1.85; 95% CI 1.41-2.43; p < 0.01). CONCLUSION Mitral valve repair provides better short-term and long-term event-free survival for rheumatic patients. With an acceptable reoperation rate, MVP is also more beneficial by avoiding troublesome lifelong anticoagulation. Thus, whenever possible, MVP should be attempted in patients with RHD.

Abstract
Rheumatic heart disease is still a major cause of mitral valve dysfunction in developing countries. We present our early results of rheumatic mitral valve repair. From August 2009 through July 2011, 60 patients (24 male and 36 female) with rheumatic disease underwent mitral repair. The mean age was 51.1 ± 13.8 years (range, 16-77 yr). Forty-nine patients were in New York Heart Association functional class III or IV. Repair procedures included chordal and papillary muscle splitting, secondary chordal division, mitral ring annuloplasty (n=58), commissurotomy (n=36), chordal replacement (n=9), posterior leaflet extension (n=4), annular decalcification (n=2), and quadrangular resection (n=2). Secondary procedures included tricuspid ring annuloplasty, left atrial ablation, obliteration of left atrial appendage, aortic valve replacement, and left atrial reduction. The early (30-d) mortality rate was 1.7%. The mean follow-up time was 14.9 ± 5 months (range, 4-26 mo). Follow-up echocardiography revealed trivial or no mitral regurgitation (MR) in 35.5% and mild (1+) MR in 49.1% of patients. Only 1 patient presented with severe (3+) MR. The mean MR grade decreased from 3.2 ± 0.9 to 0.3 ± 0.4 postoperatively (P=0.001). Left ventricular end-diastolic diameter and left atrial diameter significantly decreased postoperatively (P=0.006 and P=0.001, respectively). The mean gradient over the mitral valve decreased significantly from 11 ± 5.9 mmHg to 3.5 ± 1.8 mmHg (P=0.001). Because current techniques of mitral repair can effectively correct valve dysfunction in most patients with rheumatic disease, the number of repair procedures should be increased in developing countries to prevent complications of mechanical valve placement.

Abstract
BACKGROUND AND AIM OF THE STUDY In developing countries rheumatic heart disease is the predominant indication for cardiac surgery. As the disease tends to progress, reoperation rates for mitral valve repairs are high. Against this background, the predictors of failure were assessed and the overall performance of repairs compared with replacements in a 10-year cohort of rheumatic single mitral valve procedures. METHODS Between 2000 and 2010, a total of 646 consecutive adult (aged >15 years) patients underwent primary, single mitral valve procedures. All 87 percutaneous balloon valvuloplasties (100%) were rheumatic, compared to 280 of the 345 primary mitral valve replacements (81%) and 69 of the 215 primary mitral valve repairs (32%). As the study aim was to compare the outcome of mitral valve repair versus replacement in rheumatic patients of a threshold country, all 69 repair patients were propensity-matched with 69 of the replacement patients. Based on propensity score analysis, Kaplan-Meier actuarial analysis with log-rank testing was used to evaluate survival and morbidity. RESULTS The follow up was 100% complete (n = 138), and ranged from 0.6 to 132 months (mean 53.3 +/- 36.5 months). Actuarial freedom from valve-related mortality was 96 +/- 3% and 92 +/- 4% at five years, and 96 +/- 3% and 80 +/- 11% at 10 years for repairs and replacements, respectively (p = NS). Actuarial freedom from all valve-related events (deaths, reoperations and morbidity) was 80 +/- 6% and 86 +/- 5% at five years, and 70 +/- 8% and 69 +/- 11% at 10 years (p = NS). Actuarial freedom from all valve-related events was 57 +/- 11% and 96 +/- 3% at five years (p = 0.0008), and 42 +/- 12% and 96 +/- 3% at 10 years (p < 0.001) for those mitral valve repairs with and without commissural fusion, respectively (p = 0.0002 overall). CONCLUSION The long-term results for mitral valve replacement in an indigent, rheumatic heart disease population of a developing country were better than generally perceived. Notwithstanding, mitral valve repair has a superior long-term outcome in those patients who do not show commissural fusion at operation.

Abstract
BACKGROUND AND AIM OF THE STUDY Rheumatic mitral valve disease presents a surgical and a medical challenge to surgeons in the developing and developed world. Comprehensive reproducible repair techniques of the anatomic units in individual patients are required to restore the normal mitral valve anatomy and function. METHODS Between April 1986 and December 2009, a total of 2,211 patients underwent mitral valve repair at the authors' institution. Of these patients, 50 (32 women, 18 men) underwent repair at a median age of 45.6 years. Pure mitral stenosis was identified in four cases (8%), pure mitral regurgitation in 37 (74%), and mixed lesions in nine (18%). Posterior leaflet plication, Paneth posterior suture and autologous pericardial strip annuloplasty, chordal transfer and papillary muscle splitting were used to repair a rheumatically diseased mitral valve with leaflet prolapse, annulus dilatation and elongated or restricted chordae and malformed papillary muscle. RESULTS Three deaths (6%) occurred in hospital (< or = 30 days), and 14 late deaths occurred between 60 days and 14 years. The overall survival was 94.1 +/- 3.3%, 87.5 +/- 4.8%, 84.7 +/- 5.4%, 66.9 +/- 7.9% and 50.2 +/- 9.3% at 30 days and one, five, 10 and 15 years, respectively. Successful repair was achieved in 39 cases (78%). Actuarial freedom from severe mitral regurgitation and reoperation at one, five and 10 years was 92.7 +/- 4.1%, 77.3 +/- 7.2% and 53.4 +/- 9.6%, respectively, and was 78% for Paneth posterior suture and autologous pericardial strip annuloplasty at five and 10 years. The linearized rate for reoperation in the age groups < 20 years and > 20 years was 4.5%/pt-yr (range: 2.0-10.2%/pt-yr) and 4.3%/pt-yr (range: 2.5-7.2%/pt-yr), respectively. CONCLUSION Mitral valve repair in rheumatic disease is feasible, but the results are suboptimal. Pure mitral incompetence may be reparable and long-lasting, whilst mixed lesions may be reparable but fail subsequently. The predictability of repair and long-term functional results was determined by perioperative echocardiographic evaluation and the application of an appropriate repair technique to treat the complex pathology of the mitral valve apparatus.

Abstract
BACKGROUND Congestive cardiac failure (CCF) has emerged as a major public health problem worldwide and imposes an escalating burden on the health care system. OBJECTIVE To determine the causes and mortality rate of CCF in the University of Port Harcourt Teaching Hospital (UPTH), south Nigeria, over a five-year period from January 2001 to December 2005. METHODS A retrospective study of CCF cases were identified from the admission and discharge register of the medical wards of UPTH and the case notes were retrieved from the medical records department and analyzed. RESULTS There were 423 patients: 242 males and 181 females. Their ages ranged from 18 to 100 years with a mean of 54.4 +/- 17.3. The commonest causes of CCF were hypertension (56.3%) and cardiomyopathy (12.3%). Chronic renal failure, rheumatic heart disease, and ischemic heart disease accounted for 7.8%, 4.3%, and 0.2% of CCF, respectively. Peripartum heart disease was rare despite being commonly reported in northern Nigerian females. Eighteen patients died from various complications with a mortality rate of 4.3%. CONCLUSION The burden of CCF in the Niger Delta is mainly attributed to hypertension. Efforts should be geared towards hypertension awareness, detection, treatment, and prevention in the region.

Abstract
Mitral valve repair is a better therapeutic alternative than valve replacement for rheumatic valve disease in children. Repair procedures are especially well suited to developing countries where heart prostheses and life-long anti-coagulation therapy are largely unaffordable. The purpose of this study was to evaluate medium-term outcome of mitral valve repair in children in Senegal. A retrospective review was conducted in a cohort of 100 patients who underwent mitral valve repair for rheumatic mitral lesions over the 8-year period from 1999 to 2007. Mean age was 12 +/- 5 years (range, 7 to 17 years). The most common symptom of valve disease was dysypnea (stage IV in 26 cases and stage III in 74). Valve lesions were complex with anterior leaflet prolapse in 62 cases, posterior leaflet restriction in 35, commissural fusion in 30, and fusion of chordaes in 54. Repair procedures consisted of transfer and shortening of chordaes in 73 cases in association with commissurotomy in 22 cases and cleft closure in 17. Ring annuloplasty was performed in 84 patients. Hospital mortality was 2%. Postoperative morbidity was characterized by residual mitral regurgitation in four cases. Mean follow-up was 5 years. No late deaths were observed. Outcome was satisfactory in 84 patients with low-grade mitral regurgitation (grade I-II). Reduction of left ventricle diameter was statistically significant during systole and diastole, i.e., from 29.5 +/- 6.2 mm to 33.1 +/- 5.3 mm (p<0.05) and from 47.1 +/- 8.6 mm to 50.5 +/- 9.4 mm (p<0.05) respectively. Improvement in cardiac function was not significant, i.e., from 63.3 +/- 4.8% to 62 +/- 6.4% (p = 0.99). Mitral valve repair was successful in stabilizing myocardial function and remodeling the left ventricle. Outcome is dependent on careful patient selection and evaluation of lesions. Middle-term outcome is encouraging.

Abstract
BACKGROUND AND AIM OF THE STUDY Rheumatic heart disease is the most common cause of multivalvular disease in developing countries. Unless aggressive and timely intervention in the form of valve replacement is pursued, the condition progresses rapidly to disability and death. Combined mitral-aortic valve replacement represents a major technical challenge, and carries high early and late mortality rates. METHODS The course of 382 consecutive hospital survivors of combined mitral-aortic valve replacement, operated on between January 1992 and December 2006, was reviewed. The valve of choice for the mitral position was the Starr-Edwards (98%), while Medtronic-Hall and St. Jude Medical valves were favored for the aortic position (81%). RESULTS The mean postoperative follow up was 64.8 +/- 53.9 months, with a total cumulative follow up of 1,792 patient-years (pt-yr); the follow up was 87% complete (n=332). Late death occurred in 29 patients (8.7%). Long-term survival at five, 10 and 15 years was 92%, 78% and 45%, respectively, with a mean survival of 153 months. The linearized rates of thromboembolism, anticoagulation-related hemorrhage and prosthetic valve endocarditis were 1.06, 2.41 and 0.334% per pt-yr, respectively. CONCLUSION Among the rheumatic population, double valve replacement offers excellent symptomatic improvement and favorable late survival. Hemodynamic superiority and thromboresistance are the normal selection criteria for these prostheses, although the surgeon's experience, and the ease of insertion, availability and cost of the valve also play important roles. A strict adherence to optimal anticoagulation levels optimizes protection against thromboembolism and anticoagulation-related hemorrhage, and helps to provide the patient with a good quality life.

Abstract
BACKGROUND Rheumatic fever (RF) and rheumatic heart disease (RHD) are still major medical and public health problems mainly in developing countries. Pilot studies conducted during the last five decades in developed and developing countries indicated that the prevention and control of RF/RHD is possible. During the 1970s and 1980s, epidemiological studies were carried out in selected areas of Cuba in order to determine the prevalence and characteristics of RF/RHD, and to test several long-term strategies for prevention of the diseases. METHODS Between 1986 and 1996 we carried out a comprehensive 10-year prevention programme in the Cuban province of Pinar del Rio and evaluated its efficacy five years later. The project included primary and secondary prevention of RF/RHD, training of personnel, health education, dissemination of information, community involvement and epidemiological surveillance. Permanent local and provincial RF/RHD registers were established at all hospitals, policlinics and family physicians in the province. Educational activities and training workshops were organised at provincial, local and health facility level. Thousands of pamphlets and hundreds of posters were distributed, and special programmes were broadcast on the public media to advertise the project. RESULTS There was a progressive decline in the occurrence and severity of acute RF and RHD, with a marked decrease in the prevalence of RHD in school children from 2.27 patients per 1,000 children in 1986 to 0.24 per 1,000 in 1996. A marked and progressive decline was also seen in the incidence and severity of acute RF in five- to 25-year-olds, from 18.6 patients per 100,000 in 1986 to 2.5 per 100,000 in 1996. There was an even more marked reduction in recurrent attacks of RF from 6.4 to 0.4 patients per 100,000, as well as in the number and severity of patients requiring hospitalisation and surgical care. Regular compliance with secondary prophylaxis increased progressively and the direct costs related to treatment of RF/RHD decreased with time. The implementation of the programme did not incur much additional cost for healthcare. Five years after the project ended, most of the measures initiated at the start of the programme were still in place and occurrence of RF/RHD was low.

Abstract
AIM Rheumatic mitral patients reach their fifth decade of life more often now than in the past. The purpose of this study is to provide insight into improving morbidity and mortality in these patients. METHODS This retrospective study included 105 patients aged 50 years or more. Seventy-five underwent mechanical valve replacement and 30 received a bioprosthetic valve. Data were collected from medical records and outpatient department (OPD) registers. Follow-up included transthoracic 2D echocardiography, supported by clinical parameters, and X-ray findings. RESULTS Mean age was 58.52+/-2.4 years. Follow-up period ranged from one to eleven years (mean 6.8+/-0.9 years). Immediate perioperative mortality included five patients (4.76%) and long term mortality included three patients (3%). 35 patients previously underwent closed and open commissurotomy and balloon valvotomy. Multivariate analysis showed age, repeat surgery, atrial fibrillation, tricuspid valve disease, and preoperative functional status to be incremental risk factors. Freedom from repeat operation at 3 and 6 years was 90% and 85% in group I (<60 years), respectively. Actuarial survival at 4 and 6 years of follow up was 94.24% and 88.52%, respectively. CONCLUSION With improving life expectancy and early interventions, the number of < or = 50-year old rheumatic valvular disease patients is increasing. The present study showed a marked improvement for this subset of patients, although age still remains the main risk factor along with atrial fibrillation, repeat surgery, stroke and tricuspid valve disease.

Abstract
OBJECTIVE To describe the outcome of valve surgery, for rheumatic heart disease (RHD) and non-RHD, in residents of Cape York Peninsula and the Torres Strait Islands referred to the Cairns Base Hospital specialist outreach service. DESIGN AND PARTICIPANTS Retrospective review of medical records on all patients residing in the outreach area who had surgery for valvular heart disease between 1 January 1992 and 31 December 2004. MAIN OUTCOME MEASURES Operation type and perioperative characteristics; 5- and 10-year survival rates; reoperation rates; complications. RESULTS Forty-seven patients met the selection criteria; the median age was 40 years (range, 4-76 years); and 39 patients were Indigenous. RHD was the predominant cause of valve dysfunction (30/47 patients). Thirty-seven patients had valve replacements, six had valve repair and four had balloon valvotomy as the initial procedure. There were three bleeding complications, two episodes of operated valve endocarditis, and six embolic complications. There were nine valve-related deaths (six in the first 5 years). At 5 years, all seven patients who had had valve repair or balloon valvotomy were alive. Seven of the 47 patients required reoperation. Survival analysis showed freedom from valve-related deaths to be 83% (95% CI, 66%-92%) at 5 years and 61% (95% CI, 33%-80%) at 10 years. Freedom from reoperation at 5 years was 88% (95% CI, 71%-95%). Among the 30 patients with RHD, freedom from valve-related death was 80% (95% CI, 60%-92%) at 5 years and 52% (95% CI, 21%-75%) at 10 years. In patients with RHD, freedom from reoperation at 5 years was 87% (95% CI, 65%-96%). CONCLUSION Valvular heart disease results in substantial morbidity and mortality, despite intervention. Efforts need to focus on prevention of rheumatic fever and closer follow-up.

Abstract
BACKGROUND Triple valve surgery (TVS) is still of choice for advanced rheumatic heart disease (RHD), which has been associated with reported poor early and late outcomes. We describe the short- and long-term results after TVS in last two decades in Mainland China. METHODS From January 1985 to January 2005, a total of 871 patients (217 men, 654 women), with mean age of 42+/-11 years, underwent primary TVS for isolated advanced RHD. All patients received replacement procedures in mitral and aortic position (845 mechanical, 26 bioprosthetic), and 840 patients received repair procedures and the other 31 received replacement procedures in tricuspid position (9 mechanical, 22 bioprosthetic). Preoperative, perioperative, and postoperative data were retrospectively analyzed and risk factors affecting early and late survival were evaluated. RESULTS The 30-day hospital mortality was 8% (n=71). Presence of ascites, New York Heart Association (NYHA) class IV and lower left ventricular ejection fraction (LVEF) were identified as independent risk factors for hospital mortality. Overall long-term survival rate was 71%+/-3% at 5 years, and 59%+/-5% at 10 years. The cardiac survival rate was 75%+/-3% at 5 years and 63%+/-4% at 10 years. The event-free survival rate at 5 years and 10 years was 61%+/-6% and 41%+/-13%, respectively. Multivariate analysis revealed advanced age, NYHA class IV and lower LVEF were associated with increased late mortality. The freedom from thromboembolism and anticoagulation-related hemorrhage at 10 years was 90%+/-4% and 81%+/-5%, respectively. Of the 508 patients still alive, 376 (74%) were in NYHA class I and II. CONCLUSIONS Primary TVS for advanced RHD appears to offer satisfactory short- and long-term results with excellent symptomatic improvement. Cardiac-related late mortality following TVS may be improved by early surgical treatment before NYHA class IV or deterioration of LVEF occurs.

Abstract
BACKGROUND This study was designed to prospectively investigate the effects of total or partial chordal-sparing and chordal-nonsparing mitral valve replacement (MVR) procedures on regional and global ventricular function in a rheumatic population using sequential multiple-gated acquisition scan. METHODS One hundred five consecutive patients undergoing different techniques of chordal preservation procedures during MVR are included in this prospective study. Fifteen patients had complete excision of the chordopapillary apparatus (group 1), 34 had total chordal preservation (group 2), and 56 had preservation of the posterior chordopapillary apparatus (group 3). Radionuclide-derived left ventricular ejection fraction (LVEF) and regional wall motion (RWM) studies on 99 survivors were performed preoperatively, at discharge, at 1 year, and at 2 years. RESULTS At discharge, there was a decline in LVEF in all the 3 groups. Statistically significant improvement in ejection fraction occurred in the chordal preservation groups (2 and 3) (P < .05) as compared with the nonchordal group immediately and late postoperatively. Only the total chordal group (2) demonstrated complete recovery of LVEF by 2 years postoperatively. Significant and persistent RWM abnormalities were noted in both the nonchordal and posterior chordal groups. CONCLUSIONS We conclude that complete retention of the chordopapillary apparatus during MVR provides superior results compared with nonchordal and partial chordal preservation in terms of preservation of LVEF and reduced incidence of abnormal postoperative RWM.

OBJECTIVE The aim of this study is to detect the risk factors for hospital mortality in patients who underwent reoperative mitral valve replacement. METHODS Rheumatic mitral valve patients who underwent primary mitral valve replacement (386 cases) and repeat mitral valve replacement (94 cases) were analysed retrospectively. The incremental effects of the reoperative procedure on hospital mortality were studied by comparing primary and reoperative procedures and analyzing a series of possible predisposing factors. RESULTS Operative mortality for repeat procedures was found significantly higher than the first operations (respectively 12.8% versus 4.3%, p=0.022). Risc factors affecting the hospital mortality in reoperation group were determined as advanced age, diameter of left atrium, prolonged bypass time and development of postoperative low output state. The indication for surgery also had a significant role in patients' outcome. Mortality found significantly higher in cases operated due to endocarditis or mitral mechanical valve thrombosis compared to other reoperation groups. CONCLUSION Patients over age of 70 years, with a left atrial diameter over 60 mm, reoperated due to endocarditis and mechanical valve thrombosis, should be reevaluated for risk assessment while giving the decision of optimal operation timing. Especially patients with left ventricular hypertrophy and decreased myocardial reservoirs, efficient myocardial protection during the operation had an important role.

Abstract
Rheumatic heart disease, the sequel of acute rheumatic fever, is a very common cause of cardiovascular mortality and morbidity all over the world, and is the predominant indication for cardiac surgery in the industrialized countries. Diagnosis of rheumatic chronic carditis may sometimes be difficult because valvular regurgitation may not always be detected by routine clinical auscultation. A recent report from the World Health Organization Expert Committee recognizes the usefulness of echocardiography Doppler in providing supporting evidence for diagnosis of rheumatic carditis in the presence of equivocally pathological murmur, and recommends that patients with subclinical carditis should be managed as rheumatic heart disease until proven otherwise, because the disease still represents a major health problem. The aim of this review is to give an update on the disease by underlining changes made by the World Health Organization on disease diagnosis and patient management.

Abstract
OBJECTIVE To assess the results of aortic valve replacement with the pulmonary autograft in patients with rheumatic heart disease. METHODS From October 1993 through September 2003, 81 rheumatic patients with aortic valve disease, mean age 29.5+/-11.9 years (11-56 years) underwent, the Ross procedure with root replacement technique. Forty patients were 30 years of age or below (young rheumatics). Associated procedures included mitral valve repair (n=19), open mitral commissurotomy (n=15), tricuspid valve repair (n=2), and homograft mitral valve replacement (n=2). RESULTS Early mortality was 7.4% (six patients). Mean follow-up was 92.3+/-40.9 months (7-132 months, median 109 months). Sixty of the 73 patients whose follow-up was available (82%) had no significant aortic regurgitation. Re-operation was required in seven (8.4%) patients for autograft dysfunction with failed mitral valve repair (n=3), autograft dysfunction alone (n=2) and failed mitral valve repair alone (n=2). No re-operations were required for the pulmonary homograft. There were six (7.5%) late deaths. Actuarial survival and re-operation-free survival at 109 months were 84.5+/-4.1% and 90.5+/-3.7%, respectively. Freedom from significant aortic stenosis or regurgitation was 78.4+/-5.2% and event-free survival was 64.6+/-5.8%. When compared to rheumatics above 30 years of age, the relative risk of autograft dysfunction was high in the young rheumatics. CONCLUSION The Ross procedure is not suitable for young patients with rheumatic heart disease. However, it provides acceptable mid-term results in carefully selected older (>30 years) patients with isolated rheumatic aortic valve disease.

Abstract
OBJECTIVE To investigate the appropriate methodology and outcome of surgical treatment of tricuspid regurgitation late after valve replacement of left heart. METHODS Eighteen patients with tricuspid insufficiency, with the diagnosis conformed by echocardiogram and in New York Heart Association (NYHA) class III to IV, were treated surgically 3 to 14 years after left heart valve replacement, including 13 mitral valve replacements and 5 double valve replacements, from January 1995 to May 2004. DeVega was used in 5 patients. The ages at the time of tricuspid surgery ranged from 35 to 65 years (median 50 years). The patients were followed up for 36.7 months (12-114 months). RESULTS There was no death from hemorrhage because of re-open. Tricuspid repair was performed in 8 patients, tricuspid replacement was done in 10 patients, 5 bioprostheses and 5 mechanical valves were implanted. The hospital mortality was 16.7%. Among the survivors, the three-year survival rate was 78.8%. Twelve patients showed improvement of symptoms, while there was no improvement in 3 patients who needed medical therapy. CONCLUSION The pathophysiology of tricuspid regurgitation is associated with delayed left heart operation, implement of tricuspid repair in the first operation or progressive right ventricular failure. The surgical intervention should be earlier before the onset of severe right ventricular failure Tricuspid valve repair is the procedure of choice, while tricuspid valve replacement is also acceptable.

Abstract
The objectives of this study were to review the efficacy of percutaneous transvenous mitral commissurotomy (PTMC) in young children less than 12 years of age and to provide intermediate-term follow-up data. There is a paucity of information regarding the long-term efficacy of PTMC done in children less than 12 years of age. The data of 100 consecutive children less than 12 years of age (mean, 11.1 +/- 1.2 years) who underwent PTMC using Inoue balloon were analyzed retrospectively. Serial clinical and echocardiographic follow-up information of more than 6 months was available in 94 patients. The procedure was successful in 94 patients. The mean calculated mitral valve area (MVA) increased from 0.72 0.14 to 1.7 0.35 cm(2) (P 0.0001). Echocardiographic restenosis (MVA < or = 1 cm(2) or > 50% gain loss) occurred in 14 of 94 patients (16%) over a mean follow-up of 34.4 25.9 (range, 2-115) months. The improvement in New York Heart Association (NYHA) functional class was maintained in most patients (from a mean of 2.87 0.5 pre-PTMC to 1.42 0.6 at follow-up). Seven out of 14 patients with restenosis underwent a re-PTMC. The actuarial rate of good functional status (survival, no repeat interventions, and NYHA class 1 or 2) at 100 months was 75.4% 8.7%. PTMC provides excellent intermediate-term palliation even in young children with rheumatic mitral stenosis.

Abstract
OBJECTIVES To investigate the progress of rheumatic fever (RF) and the predictors of severe chronic valvar disease. DESIGN Patients prospectively followed up since their first attack of acute RF (ARF). SETTING Universidade Federal de Minas Gerais, Brazil. PATIENTS 258 children and adolescents who met the revised Jones criteria for RF. The follow up period ranged from 2-15 years. MAIN OUTCOME MEASURES The presence and severity of mitral or aortic valvar disease were determined by both clinical and Doppler echocardiographic examinations. The variables associated with severe chronic valvar disease were initially identified by the Kaplan-Meier method and, later, by multivariate analysis. RESULTS Doppler echocardiography of 258 patients studied showed that 186 (72.1%) developed chronic valvar disease and 41 (15.9%) progressed to severe chronic mitral or aortic lesions. Of 146 patients who developed carditis, 49 (33.6%) had a normal clinical examination in the chronic phase but only nine (6.2%) had normal Doppler echocardiographic findings--that is, 40 (27.4%) patients progressed to chronic subclinical valvar disease. Moderate or severe carditis, recurrences of ARF, and mother's low educational level were risk factors in predicting severe chronic valvar diseases. CONCLUSION The increased risk of progressing to severe chronic valvar disease was associated with moderate or severe carditis, recurrences of ARF, and mother's low educational level. Hence, in a country such as Brazil, the options available for disease control are mainly primary and secondary prophylaxis.

Abstract
OBJECTIVE The aim of this study was to assess the maternal and perinatal outcome of pregnancies complicated by cardiac disease in a tertiary care center in Egypt. METHODS During a 1-year period, a total of 86 pregnant women with cardiac disease were admitted. Maternal and perinatal morbidity and mortality were calculated and compared with a control group. RESULTS Seventy-seven (89.5%) patients were due to rheumatic affection, and 60 patients were classified as NYHA classes I-II. There was one case of maternal mortality (1.16%), and 10 other cases developed life-threatening complications. Two perinatal mortalities (2.32%) occurred in this series. Birth weight of babies born to mothers with functional classes III and IV were significantly lower than those of functional classes I-II and control group. CONCLUSION Rheumatic heart disease with pregnancy is still predominant in Egypt. Maternal and perinatal morbidity and mortality are strongly correlated to maternal cardiac functional classification.
