Abstract
BACKGROUND Aortic valve reconstruction using glutaraldehyde-treated autologous pericardium, also called Ozaki procedure, is a surgical procedure for patients with aortic valve disease. Gratifying results have been reported in adult patients, however, limited published data is available in paediatric population. This study looked at clinical characteristics and early outcomes of children who underwent Ozaki procedure at our Institute. METHODS This was a retrospective descriptive study conducted on children who underwent aortic valve reconstruction at Jakaya Kikwete Cardiac Institute (JKCI) from January 2019 through December 2022. Medical records of these children were reviewed to extract data on demographics, clinical characteristics, redo surgical interventions and survival. RESULTS A total of 10 children underwent Ozaki procedure during the study period. Eight children had severe aortic regurgitation while 2 had severe aortic stenosis preoperatively. All children had either none or trivial aortic regurgitation immediately after surgery. None of them had redone operations throughout the follow-up period. There was no in-hospital mortality, however, one child died one-year after surgery. The mean follow-up period was 1.6 years with the longest follow-up time of 4 years. CONCLUSION Ozaki procedure showed encouraging early results among children with aortic valve disease who underwent surgical repair by this technique. Future studies with larger sample sizes and longer follow up periods to evaluate long-term results in this population are recommended.

Abstract
INTRODUCTION Surgical intervention is an important treatment modality for advanced rheumatic heart disease (RHD). This study aimed to describe patient characteristics and outcomes from cardiac surgery for RHD in patients referred to the only tertiary paediatric hospital in Western Australia. METHODS An analysis of patient characteristics and cardiac surgery outcomes in patients with RHD was undertaken, using data from clinical cardiac databases, medical notes, and correspondence from rural outreach clinics. RESULTS 29 patients (59% female, 97% Aboriginal, Māori or Pacific Islander) underwent 41 valve interventions over 34 cardiac surgeries for RHD between 2000-2018. Median age at first surgery was 12.2 (range 4-16) years. Severe mitral regurgitation (MR) was the most common indication for primary surgery (62%), followed by mixed mitral regurgitation/aortic regurgitation (21%) and severe aortic regurgitation (17%). Mitral valve repair was the most common valve intervention (56%). Two patients had mitral valve replacement (MVR) at first operation, two patients had MVR at second operation and two had MVR at third operation. There was no early mortality. One patient required early (<30 days) reoperation for aortic valve repair failure. Two patients had late reoperations at 3.3 and 6.1 months after the first procedure for MR. Four (14%) patients experienced documented ARF recurrences. Late mortality occurred in 3 (10%) patients, all due to cardiac causes. On last follow-up echocardiogram 5 patients (17%) had moderate MR and none had severe MR. CONCLUSIONS This is the first study to describe characteristics and outcomes in WA paediatric patients having surgery for RHD. Outcomes are comparable to similar studies, with favourable long-term survival.

Abstract
Rheumatic heart disease (RHD) is commonly seen in people from developing and low-income countries. More cases are being recorded in developed countries due to migration and globalization. RHD develops in people with a history of rheumatic fever; it is an autoimmune response to group A streptococcal infection due to similarities at the molecular level. Congestive heart failure, arrhythmia, atrial fibrillation, stroke, and infective endocarditis are a few of the many complications associated with RHD. Here we present a case of a 48-year-old male with a past medical history of rheumatic fever at the age of 12 years, who presented to the emergency room (ER) complaining of bilateral ankle swelling, dyspnea on exertion, and palpitations. The patient was tachycardic with a heart rate of 146 beats per minute and tachypneic with a respiratory rate of 22 breaths per minute. On physical exam, there was a harsh systolic and diastolic murmur at the right upper sternal border. A 12-lead electrocardiogram (EKG) revealed atrial flutter with a variable block. Chest X-ray revealed an enlarged cardiac silhouette with a pro-brain natriuretic peptide (proBNP) of 2,772 pg/mL (normal ≤ 125 pg/mL). The patient was stabilized with metoprolol and furosemide and was admitted to the hospital for further investigation. Transthoracic echocardiogram showed left ventricular ejection fraction (LVEF) of 50-55% with severe concentric hypertrophy of the left ventricle with a severely dilated left atrium. Increased thickness of the aortic valve with severe stenosis and a peak gradient of 139 mm Hg and a mean gradient of 82 mm Hg was noted. The valve area was measured to be 0.8 cm2. Transesophageal echocardiogram showed a tri-leaflet aortic valve with commissural fusion of valve cusps with severe leaflet thickening consistent with rheumatic valve disease. The patient underwent tissue aortic valve replacement with a bioprosthetic valve. The pathology report showed extensive fibrosis and calcification of the aortic valve. The patient came in for a follow-up visit 6 months later and expressed feeling better and more active.

Abstract
Rheumatic heart disease is a serious ailment with significant morbidity and mortality in endemic areas; yet, there is no agreement on indication, timing, and surgical modality for treating rheumatic valve affection. There is mounting evidence that rheumatic mitral valve repair is possible with good long-term results, less is the case with rheumatic aortic valve disease. We discuss the surgical approach for both valves emphasizing the role of multimodality imaging.

Abstract
Valvuloplasty for rheumatic aortic valve disease remains controversial. We conducted this study to explore whether aortic valvuloplasty is appropriate for the rheumatic population. A comprehensive search was conducted, and 7 eligible retrospective studies were identified from PubMed, Embase, Medline and Cochrane (up to April 7, 2020) according to the inclusion and exclusion criteria. The data for hospital mortality, 5-year survival, 5-year reoperation, aortic insufficiency grade (AIG) and aortic valve gradient (AVG) were extracted by 2 independent reviewers and were analysed to evaluate the safety and availability of aortic valvuloplasty for rheumatic patients. The heterogeneity of the results was estimated using the Q test and I2 statistics. The fixed pooling model was used when I2 ≤ 50%; otherwise, the random pooling model was selected. 7 articles with 418 patients were included. The pooled hospital mortality, 5-year survival and 5-year reoperation rates were 3.2%, 94.5% and 9.9%, respectively. The heterogeneities of the weighted mean differences (WMD) values of the AIG and AVG between preoperation and postoperation were extremely high (I2 = 81.5%, p < 0.001 in AIG, I2 = 97.6%, p = 0.003 in AVG). Subgroup analysis suggested that the AIG and AVG were improved by 3.03 grades (I2 = 0%, p < 0.001) and 3.16 mmHg (I2 = 0%, p < 0.001) in the European group, respectively. In the Asian group, the AIG and AVG were improved by 2.57 grades (I2 = 0%, p < 0.001) and 34.39 mmHg (I2 = 0%, p < 0.001), respectively. Compared with the values at discharge, the AIG was increased by 0.15 grades (I2 = 0%, p = 0.031) and the AVG was still decreased by 2.07 mmHg (I2 = 0%, p = 0.031) at the time of follow up. Valvuloplasty is safe and effective to treat rheumatic aortic insufficiency and stenosis, and the duration of maintenance required to improve stenosis was longer than that of insufficiency.

Abstract
Rheumatic heart disease (RHD) remains the most common cardiovascular disease in young adults and adolescents in need of heart surgery in low- and middle-income countries (LMICs). The mean age of patients is 20-25 years, often much younger. By contrast, the few patients with chronic RHD in developed countries present a mean age of around 55 years. It is absolutely fundamental to differentiate these two types of population. Pathology, lesions and surgical methods are different, and the results should not be compared. It is not all the same! A certain enthusiasm for mitral repair has recently surged, with several reports showing excellent results in children and young adults, resulting from the renewed interest of cardiac surgeons, also based on new and modified techniques developed in the meantime. While surgery is easily accessible to patients in developed countries, the situation in LMICs is often dramatic, with countries where there is a complete absence of or few surgical facilities absolutely unable to meet gigantic demands. Many foreign surgical teams conduct humanitarian missions in several of these countries. They are just a "drop of water in the ocean" of needs. In some cases, however, these missions led to the establishment of local teams that now work independently and, in some cases, outperform the foreign teams still visiting.

Abstract
Currently, more than five times more people live in low- and middle-income countries (LMICs) than in high-income countries (HICs). As such, the downward trend in cardiac surgical needs in HICs reflects only the situation of one sixth of the world population while the vast majority living in LMICs has still no or limited access to life saving heart operations. In these countries, rheumatic heart disease (RHD) still accounts for a significant proportion of cardiac surgical needs. In low- and lower-middle income countries it remains the single most common cardiovascular disease in young adult and adolescent patients in need of heart surgery outweighing other indications such as congenital cardiac defects almost 4-fold. Compared to HICs with their predominance of calcific aortic stenosis in the elderly mitral valve surgery is required in >90% of the largely young patients with RHD in low-income countries (LICs) and still in 70% of the often middle aged patients in middle-income countries (MICs). Although recent government initiatives in LICs led to the establishment of local, independent cardiac surgical services gradually replacing fly-in missions, these centers still only cover less than 2% of the needs of their populations. In MICs, cardiac surgical needs continually grow with the emergence of degenerative diseases. As such, in spite of the concomitant growth of cardiac surgical capacity, significantly less than half the estimated patients in need have access. Capacities in LICs range from 0.5 to 7 cardiac operations/million population; 100-481/million in MICs and >1,200/million in HICs such as the USA and Germany. While a new level of awareness of the scope and magnitude of the problem has begun to emerge in LICs and the establishment of local cardiac surgical capacity has given rise to a glimpse of hope, the challenges of expanding these fledgling services to a significant proportion of the population still seem insurmountable. Challenges in MICs are on the other hand the widening gap between private cardiac medicine for the affluent few and overwhelmed public services for the many and the rural urban divide with the underappreciation of the ongoing dominance of RHD in the rural and indigent population on the other. Overshadowing all LMICs is the low level of valve-repair skills associated with insufficient cardiac surgical capacity and the unavailability of suitable replacement valves which address the young age of the patients and the difficulties of anticoagulation in a socioeconomic environment distinctly different from the elderly patients of HICs.

Abstract
OBJECTIVES In recent years, repair techniques for diseased aortic valves have received increasing attention. This study reports the short-term outcome of aortic valve repair (AVr) for three pathologic categories: rheumatic heart disease, aortic regurgitations (ARs) from subarterial ventricular septal defect (VSD), and infective endocarditis in order achieve the valve competency. METHODS From January 2017 to March 2019, 30 patients underwent AVr with significant AR in the National Heart Institute (NHI) and Banha university. All patients underwent echocardiography before and after the procedure; 30 patients underwent AVr with significant AR, nine patients (30%) with juxta-arterial VSD, two patients (6.66%) with infective endocarditis (IE), and 19 patients (63.33%) with rheumatic aortic valve disease. For intraoperative transesophageal echocardiography and direct examination for better clarification of the anatomy and guidance of repair after cardiopulmonary bypass (CPB), annular repair, leaflet repair by shaving, plication, triangular resection, augmentation with the pericardium, and VSD closure were done. RESULTS Only three patients developed aortic incompetence grade II, no in-hospital mortality; however, we had 3 months later mortality for one patient with IE, only one patient with rheumatic heart disease progressed from grade II to grade IV aortic incompetence (AI) and aortic valve replacement was done so AVr was successfully done for the subaortic VSD, rheumatic, and IE patients instead of replacement of the valve. CONCLUSIONS In favor of AVr, good patient selection, amenable techniques for the suitable pathology will give a good target hence the aim of the work.

Abstract
Rheumatic valve disease is an endemic problem that is responsible for substantial morbidity and mortality in many countries. Unlike the rheumatic mitral valve, aortic repair continues to be challenging. A thorough understanding of the underlying mechanisms; structural and functional, is essential for repair. We here describe various methods of repair and outline our favoured techniques.

Abstract
BACKGROUND Few centers for open heart surgery (OHS) are in Sub-Saharan Africa. Lack of OHS results is also noted. By reporting our African experience on OHS, the aim of this study was to fill the gap. METHODS It is a retrospective study on 2,612 patients who were subject to an OHS between 1978 and 2013. Data were collected from demographical, clinical, investigative studies, surgical and outcomes parameters. RESULTS There were 1,475 cases of rheumatic heart diseases (RHD), 126 endomyocardial fibrosis (EMF), 741 congenital heart diseases (CHDs) and 270 various affections. Related to rheumatic valvular surgery we enumerated 1,175 monovalvular (mitral n=778, aortic n=336, tricuspid n=61); 280 bivalvular (mitral + aortic n=150, mitral + tricuspid n=130) and 20 trivalvular. For RHD, average age was 26±10.1 years (4-69 years) and 60% of our patients presented a functional class III or IV according to New York Heart Association (NYHA) classification. A total of 1,481 valvular replacements (bioprostheses n=489, mechanical prostheses n=992) and 445 valvular repair were carried out with a global and late mortality surgery respectively at 7% and 8%. One hundred and twenty-six [126] cases of EMF with right sided form 39, left sided form 40, and bilateral form 47 were colligated. Average age was 12±0.6 years (2-15 years). All patients with EMF underwent surgery; an endocardectomy in all patients combined with valvular reconstruction (n=36) or valvular replacement (n=90) was carried out with a hospital mortality at 16% (n=20). Concerning CHD, the most frequent were ventricular septal defect (VSD) (n=240), atrial septal defect (ASD) (n=200), partial atrio-ventricular sepal defect (n=30) and tetralogy of Fallot (T4F) (n=220), a total correction was performed for those CHD with an early mortality at 6.4% (n=44). CONCLUSIONS OHS in Cote d'Ivoire was successfully performed in most of our patients, the spectrum of acquired valvular heart diseases and CHDs in our country is similar to others in Sub-Saharan Africa.

Abstract
Background Globally, rheumatic heart disease (RHD) remains an important cause of heart disease. In Australia it particularly affects younger Indigenous and older non-Indigenous Australians. Despite its impact there is limited understanding of the factors influencing outcome following surgery for RHD. Methods The Australian and New Zealand Society of Cardiac and Thoracic Surgeons Cardiac Surgery Database was analysed to assess outcomes following surgical procedures for RHD and non-RHD valvular disease. The association with demographics, co-morbidities, pre-operative status, valve(s) affected and operative procedure was evaluated. Results Outcome of 1384 RHD and 15843 non-RHD valve procedures was analysed. RHD patients had longer ventilation, experienced fewer strokes and had more readmissions to hospital and anticoagulant complications. Mortality following RHD surgery at 30 days was 3.1 % (95 % CI 2.2 – 4.3), 5 years 15.3 % (11.7 – 19.5) and 10 years 25.0 % (10.7 – 44.9). Mortality following non-RHD surgery at 30 days was 4.3 % (95 % CI 3.9 - 4.6), 5 years 17.6 % (16.4 - 18.9) and 10 years 39.4 % (33.0 - 46.1). Factors independently associated with poorer longer term survival following RHD surgery included older age (OR1.03/additional year, 95 % CI 1.01 – 1.05), concomitant diabetes (OR 1.7, 95 % CI 1.1 – 2.5) and chronic kidney disease (1.9, 1.2 – 2.9), longer invasive ventilation time (OR 1.7 if greater than median value, 1.1– 2.9) and prolonged stay in hospital (1.02/additional day, 1.01 – 1.03). Survival in Indigenous Australians was comparable to that seen in non-Indigenous Australians. Conclusion In a large prospective cohort study we have demonstrated survival following RHD valve surgery in Australia is comparable to earlier studies. Patients with diabetes and chronic kidney disease, were at particular risk of poorer long-term survival. Unlike earlier studies we did not find pre-existing atrial fibrillation, being an Indigenous Australian or the nature of the underlying valve lesion were independent predictors of survival.

Abstract
In children with rheumatic heart disease, conservative valve surgery is the best option whenever feasible. Surgeons must develop an attitude and interest in valve repair techniques that can be easily learned. Patients who undergo valve repair at an early age are at risk of requiring additional surgery over time. Mechanical valve replacement, nonetheless, should be reserved for situations where more conservative approaches are not feasible.

Abstract
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether it is best to repair or replace the aortic valve with a bioprosthesis in young patients with severe aortic regurgitation as the patients do not like to take warfarin for the rest of life. Altogether 74 papers were found using the reported search, of which 10 represented the best evidence to answer the clinical question. The authors, journal, date, country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. The results of the reported studies provided interesting results. All the studies identified are retrospective. Three papers reported the results about the Ross operation for aortic valve (AV) disease. Freedom from autograft reoperation at 10 years was from 81 to 84%, at 15 years 92% and at 18 years 51%. Freedom from aortic insufficiency (AI) (moderate to severe) at 15 years was 89.7%. Four papers reported that freedom from AV reoperation after AV repair at 5 years was from 86 to 94% and at 8 years was from 83 to 93%. Freedom from recurrent AI (>2+) at 5 years was from 85 to 94%. One study showed that reoperation-free survival after AV repair for rheumatic valve disease at 160 months was 85%. Two papers compared AV repair with aortic valve replacement (AVR) with a bioprosthetic valve and found that freedom from AV reoperation at 5 years was from 90 to 91% for the repair group and 94 to 98% for AVR. Freedom from AI (moderate or severe) at 5 years was 79% for the repair group and 94% for AVR. Aortic valve repair yielded good early and mid-term results. It is a viable alternative to replacement with a bioprosthesis, especially for young patients who did not like to take warfarin. The Ross operation appeared to be a good choice for selected patients with AV disease.

Abstract
Over the past 5 years, the advent of echocardiographic screening for rheumatic heart disease (RHD) has revealed a higher RHD burden than previously thought. In light of this global experience, the development of new international echocardiographic guidelines that address the full spectrum of the rheumatic disease process is opportune. Systematic differences in the reporting of and diagnostic approach to RHD exist, reflecting differences in local experience and disease patterns. The World Heart Federation echocardiographic criteria for RHD have, therefore, been developed and are formulated on the basis of the best available evidence. Three categories are defined on the basis of assessment by 2D, continuous-wave, and color-Doppler echocardiography: 'definite RHD', 'borderline RHD', and 'normal'. Four subcategories of 'definite RHD' and three subcategories of 'borderline RHD' exist, to reflect the various disease patterns. The morphological features of RHD and the criteria for pathological mitral and aortic regurgitation are also defined. The criteria are modified for those aged over 20 years on the basis of the available evidence. The standardized criteria aim to permit rapid and consistent identification of individuals with RHD without a clear history of acute rheumatic fever and hence allow enrollment into secondary prophylaxis programs. However, important unanswered questions remain about the importance of subclinical disease (borderline or definite RHD on echocardiography without a clinical pathological murmur), and about the practicalities of implementing screening programs. These standardized criteria will help enable new studies to be designed to evaluate the role of echocardiographic screening in RHD control.

Abstract
BACKGROUND The aim of this study was to assess the early and mid-term results of patients who underwent cardiac operations due to cardiac pathologies other than aortic valve (AV) disease, but also had mild-to-moderate aortic valve insufficiency that was repaired during the same session. METHODS A total of 43 patients who underwent AV repair for mild-to-moderate aortic insufficiency between January 2003 and February 2009, in addition to the procedure performed for their main pathology necessitating the surgical intervention, were included in the present study. Cardiac function was evaluated, before and after the operation. RESULTS Hospital mortality rate was 4.6% (two patients). After the operations, significant improvements were observed in aortic insufficiency (0.57 +/- 0.50 vs. 2.86 +/- 0.48, p = 0.001), New York Heart Association class (1.08 +/- 0.28 vs. 3.03 +/- 0.44, p = 0.001), and left atrial diameter (47.37 +/- 9.28 vs. 42.35 +/- 7.02; p = 0.001). However, left ventricular end diastolic and end-systolic diameters remained unchanged. Two patients were re-operated for AV disease during the follow-up period; thus, at five years, the rate of freedom from re-operation due to AV pathology was 90.7 +/- 6.3%. CONCLUSIONS Cusp shaving is a feasible option that can be performed with low risk for concomitant aortic insufficiency.

Abstract
Valve repair in children is technically demanding but more desirable than valve replacement. From April 2004 to September 2005, 1 boy and 8 girls with rheumatic heart disease, aged 2–13 years (median, 9 years), underwent valve repair for isolated mitral regurgitation in 5, combined mitral and aortic regurgitation in 2, mitral stenosis in 1, and mitral regurgitation associated with atrial septal defect in 1. Chordal shortening in 7, annular plication in 6, commissurotomy in 1, reconstruction of commissural leaflets in 7 were performed for mitral valve disease. Plication and reattachment of the aortic cusps was carried out in 2 patients. Annuloplasty rings were not used. All patients survived the operation, 8 had trivial or mild residual mitral regurgitation, and 1 had trivial aortic regurgitation. Mean left atrial pressure decreased from 14 to 7 mm Hg postoperatively. During follow-up of 3–18 months, all children were asymptomatic and enjoyed normal activity. None required reoperation. In addition to chordal shortening and annular plication, reconstruction of the commissural leaflets is considered the most important aspect of valve repair. It can be achieved without annuloplasty rings, giving good early and midterm results.

Abstract
The mitral, aortic, and tricuspid valves can be repaired, in experienced hands. Durability of repair, especially for the mitral valve, compares favorably to valve replacement. Repair of cardiac valves enables many patients to be free of life-long anticoagulation, maintain their native valve structure, reduce their risk for endocarditis, and avoid complications associated with prosthetic valve implants.

Abstract
Aortic valve repair and valve-sparing aortic root replacement are attractive concepts because they offer the possibility of valve competence without structural deterioration due to nonviability and they preclude the need for anticoagulation. Enthusiasm for aortic valve repair has waxed and waned over the past 45 years due in part to the inherent technical difficulties and poor mid-term results. Renewed interest in the concept of aortic valve repair has paralleled the development of valve-sparing aortic root replacement over the last 20 years. A current perspective on aortic valve repair and valve-sparing aortic root replacement is presented in the following review. Historical background, indications for repair, technical considerations, and outcomes data are discussed.
