INTRODUCTION: Cardiovascular diseases in pediatric pathologies have emerged in the recent years in sub-Saharan Africa (SSA), with congenital heart diseases (CHDs) being the most frequent. Unfortunately, their diagnosis is usually delayed, thereby increasing childhood morbidity and mortality. OBJECTIVES: Describe the clinical, echocardiographic, and therapeutic aspects of CHDs of children at Douala General Hospital. METHODS: We carried out a cross-sectional descriptive study over a 10-year period, from January 2006 to December 2015...

The burden of illness associated with acquired cardiac disease in children in low-income and middle-income countries (LMIC) is significant and may be equivalent to that of congenital heart disease. Rheumatic heart disease, endomyocardial fibrosis, cardiomyopathy (including HIV cardiomyopathy) and tuberculosis are the most important causes. All are associated with poverty with the neediest children having the least access to care. The associated mortality and morbidity is high. There is an urgent need to improve cardiac care in LMIC, particularly in sub-Saharan Africa and parts of Southeast Asia where the burden is highest...

The 54 countries in Africa have an estimated total annual congenital heart defect (CHD) birth prevalence of 300,486 cases. More than half (51.4%) of the continental birth prevalence occurs in only seven countries. Congenital heart disease remains primarily a pediatric health issue in Africa because of the deficient health-care systems: the adults with CHD made up just 10% of patients with CHD in Ghana, and 13.7% of patients with CHD presenting for surgery in Mozambique. With Africa's population projected to double in the next 35 years, the already deficient health systems for CHD care will suffer unbearable strain unless determined and courageous action is undertaken by the African leaders...

Infective Endocarditis (IE) is an endocardial infection usually caused by bacteria that affects not only the native heart valves but also, with increasing frequency intravascular implanted devices and congenital heart diseases. Despite medical advances, IE remains a life-threatening disease with substantial morbidity and mortality. In Africa, its diagnosis and treatment are still a major challenge in clinical practice. The objective of this work was to study the epidemiological, clinical features, diagnostic techniques currently used in medical practice and the range of micro-organisms that are responsible...

BACKGROUND: The incidence of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) has waned in Western countries, however that is not the situation in developing nations. METHODS: Records were reviewed of patients from the Eastern Cape municipal districts who presented to the Paediatric Cardiology Unit with ARF and RHD from January 2008 to August 2015. RESULTS: Total of 56 patients with ARF/RHD was reviewed. The majority of patients (n = 52) presented for the first time with RHD...

INTRODUCTION: Congenital heart diseases (CHD) are common causes of cardiovascular morbidity and mortality among young children and adolescents living in Africa. Accurate epidemiological data are needed in order to evaluate and improve preventive strategies. This review aims to determine the prevalence of CHD and their main patterns in Africa. METHODS AND ANALYSIS: This systematic review and meta-analysis will include cross-sectional, case-control and cohort studies of populations residing inside African countries, which have reported the prevalence of CHD, confirmed by an echocardiographic examination and/or describing different patterns of these abnormalities in Africa...

BACKGROUND: Congenital heart disease (CHD) is a common condition in children in Sub-Saharan Africa (SSA), where it is associated with poor outcomes. Diagnosis of CHD in SSA depends essentially on echocardiography, which is available only in few urban referral centers. Our aim was to assess time changes in the pattern of referral for pediatric echocardiography and the subsequent diagnosis of structural CHD in a major SSA city. METHODS: All pediatric echocardiography performed between 2004 and 2013 at the echocardiography laboratory of the Yaounde General Hospital were reviewed...

Congenital heart block (CHB) is rare disorder that has a higher mortality when associated with structural congenital heart defects. Very few cases have been reported in Sub-Saharan Africa (SSA). We present a case of complete CHB associated with a complex congenital heart defect in a neonate in Cameroon. A 1-month-old neonate in Cameroon was referred for the evaluation of bradycardia. The obstetrical ultrasound done during pregnancy revealed fetal bradycardia without further evaluation. Clinical examination showed well a developed neonate with bradycardia at 62 beats/minute, and mild cyanosis with oxygen saturation at 93% at room air...

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...

BACKGROUND: In recent decades, humanitarian cardiology and cardiac surgery have shifted toward sending short-term surgical and catheter missions to treat patients. Although this model has been shown to be effective in bringing cardiovascular care to the patients' environment, its effectiveness in creating sustainable service is questioned. This study reports the barriers to contribution of missions to effective skill transfer and possible improvements needed in the future, from the perspective of both the local and overseas teams...

COMMENT
Karen Sliwa
South Africa and other areas of sub-Saharan Africa have in the past 20 years undergone rapid demographical changes, largely due to urbanisation and changes in lifestyle. This rapid change has led to a marked increase in specific cardiac conditions, such as hypertensive heart disease and coronary artery disease (with the highest prevalence in the middle-aged population), in conjunction with a range of other heart diseases, which are historically common in Africa-eg, rheumatic heart disease, cardiomyopathies, and unoperated congenital heart disease...

BACKGROUND: There are only very few reports on Fallot's tetralogy in Africa especially from sub-Saharan Africa. At best tetralogy of Fallot (TOF) is only mentioned as part of reports of surveys of other congenital heart diseases or as case reports in the region. There has been no report on cohorts of children with TOF in West Africa. This article describes the pattern and presentation of children diagnosed with TOF patients in a tertiary hospital in sub-Saharan Africa over a 9-year period...

Management of acute viral bronchiolitis is largely supportive. There is currently no proven effective therapy other than oxygen for hypoxic children. The evidence indicates that there is no routine benefit from inhaled, rapid short-acting bronchodilators, adrenaline or ipratropium bromide for children with acute viral bronchiolitis. Likewise, there is no demonstrated benefit from routine use of inhaled or oral corticosteroids, inhaled hypertonic saline nebulisation, montelukast or antibiotics. The last should be reserved for children with severe disease, when bacterial co-infection is suspected...

Bronchiolitis may be diagnosed on the basis of clinical signs and symptoms. In a young child, the diagnosis can be made on the clinical pattern of wheezing and hyperinflation. Clinical symptoms and signs typically start with an upper respiratory prodrome, including rhinorrhoea, low-grade fever, cough and poor feeding, followed 1 - 2 days later by tachypnoea, hyperinflation and wheeze as a consequence of airway inflammation and air trapping.The illness is generally self limiting, but may become more severe and include signs such as grunting, nasal flaring, subcostal chest wall retractions and hypoxaemia...

The poorest billion people are distributed throughout the world, though most are concentrated in rural sub-Saharan Africa and South Asia. Cardiovascular disease (CVD) data can be sparse in low- and middle-income countries beyond urban centers. Despite this urban bias, CVD registries from the poorest countries have long revealed a predominance of nonatherosclerotic stroke, hypertensive heart disease, nonischemic and Chagas cardiomyopathies, rheumatic heart disease, and congenital heart anomalies, among others...

BACKGROUND: The 22q11.2 deletion syndrome (22qDS) has more than 180 associated phenotypic features, yet genotype-phenotype correlation remains obscure. Since many of the clinical characteristics are serious, yet treatable (including congenital heart disease), clinicians must maintain a high index of clinical suspicion to recognise a suite of co-occurring phenotypic features that suggest a diagnosis of 22qDS. Óskarsdottir's scoring schedule (the 'O score') is generally used to suggest the need for confirmatory fluorescent in situ hybridisation (FISH) testing, using the TUPLE 1 probe...
