Management of pregnant women with heart disease remains challenging due to the advancement of innovations in cardiac surgery and correction of complex cardiac anomalies, and more recently, with the successful performance of heart transplants, cardiac diseases are not only likely to coexist with pregnancy, but will also increase in frequency over the years to come. In developing countries with a higher prevalence of rheumatic fever, cardiac disease may complicate as many as 5.9% of pregnancies with a high incidence of maternal death...

Background: Rheumatic heart disease (RHD) following Group A Streptococcus (GAS) infections is heritable and prevalent in Indigenous populations. Molecular mimicry between human and GAS proteins triggers pro-inflammatory cardiac valve-reactive T-cells. Methods: Genome-wide genetic analysis was undertaken in 1263 Aboriginal Australians (398 RHD cases; 865 controls). Single nucleotide polymorphisms (SNPs) were genotyped using Illumina HumanCoreExome BeadChips. Direct typing and imputation was used to fine-map the human leukocyte antigen (HLA) region...

Autologous cell therapy represents a novel treatment option for vascular regeneration in different disease conditions. Both experimental and clinical studies indicate a therapeutic potential for different proangiogenic cells (PCs), including endothelial progenitor cells (EPCs) in the treatment of peripheral artery disease. A significant improvement of ischemic symptoms has been reported in different trials evaluating PCs for the treatment of critical limb ischemia. However, contrasting results from different meta-analyses question the efficacy of PC-based approaches on long-term outcomes, including amputation and survival...

BACKGROUND: Cardiac resynchronization therapy (CRT) is an established treatment for patients with advanced heart failure that results in improvement of left ventricle (LV) systolic function and LV reverse remodeling. This may have a positive effect on the size and the function of the left atrium (LA). We assessed the LA function, dimensions, and volumes before and after CRT implantation. METHODS: A total of 37 patients with mean age of 55.3 ± 9.64 years including 11 (29...

Valvular disease continues to be an important cause of morbidity and mortality across the globe with an increasing number of elderly patients affected by degenerative valvular diseases. Mitral valve disease is the most common of the valvular heart disorders, particularly in ageing populations, with a prevalence of more than 10% in people aged older than 75 years. Mitral regurgitation (MR) is divided into either primary (or organic) or secondary (or functional) MR. It is necessary to distinguish primary from secondary MR because these diseases differ not only by their cause, but also by their prognosis and management...

Aortic valve diseases are the most common among the valvular heart diseases. Significant increases in the frequency of degenerative aortic sclerosis and aortic stenosis (AS) are observed, particularly with aging of the population and diminished rheumatic heart disease. Aortic regurgitation (AR) is less common in the elderly and is accompanied by AS rather than pure AR. Considering the comorbid diseases, fragility and cognitive functions in elderly patients, special approach is needed during diagnosis, evaluation, treatment and follow-up...

Prosthetic heart valve thrombosis (PHVT) is a major cause of morbidity and mortality in patients with mechanical heart valves. We present a case of recurrent PHVT associated with eosinophilia. A 17-year-old girl underwent aortic and mitral valve replacement for rheumatic heart disease. Over a period of 4 years, she had four episodes of PHVT despite oral anticoagulation with adequate INR. Her investigations revealed eosinophilia which was missed during the previous episodes. No further episodes of PHVT occurred after treatment of eosinophilia with steroids on limited follow-up...

Group A streptococcus (GAS) infection remains a major concern due to multiple diseases including pharyngitis, impetigo, acute rheumatic fever (ARF) and rheumatic heart disease (RHD). It uses different adhesins and virulence factors like Cpa (collagen binding protein) and Scl (collagen-like protein) in its pathogenicity. Scl having similarities with human collagen may contribute to inducing autoimmunity in the host. Here we assessed gene expression, antibody titer of Cpa, Scl1 and Scl2 in both clinical GAS isolates (n=45) and blood (n=45) obtained from pharyngisis, ARF (acute rheumatic fever) and RHD respectively...

Background -Screening echocardiography (echo) has emerged as a potentially powerful tool for early diagnosis of rheumatic heart disease (RHD). The utility of screening echo hinges on the rate of RHD progression and the ability of penicillin prophylaxis to improve outcome. We report the longitudinal outcomes of a cohort of children with latent RHD and identify risk factors for unfavorable outcomes. Methods -This was a prospective natural history study conducted under the Ugandan RHD registry. Children with latent RHD and ≥1 year of follow-up were included...

Rheumatic heart disease (RHD) is the most serious manifestations of rheumatic fever, which is caused by group A Streptococcus (GAS or Streptococcus pyogenes) infection. RHD is an auto immune sequelae of GAS pharyngitis, rather than the direct bacterial infection of the heart, which leads to chronic heart valve damage. Although antibiotics like penicillin are effective against GAS infection, improper medical care such as poor patient compliance, overcrowding, poverty, and repeated exposure to GAS, leads to acute rheumatic fever and RHD...

Valvular heart disease presents as mixed spectrum lesion in healthcare settings in the third-world and developing countries. Rheumatic heart disease still forms the bulk of the aetiopathology of valve lesions. Mitral and aortic valve lesions top the list of valvular pathology. A thorough understanding of the pathophysiology of valvular heart disease is essential while planning anaesthesia and perioperative care for such patients. Meticulous use of optimal fluids, close monitoring of the changing haemodynamics and avoidance of situations that can cause major reduction of cardiac output and fluid shifts are mandatory to achieve good clinical outcome...

BACKGROUND: The non-vitamin K antagonist oral anticoagulants (NOACs) were approved for non-valvular atrial fibrillation (AF) but this term may be misnomer. Thus, the term non-mechanical and rheumatic mitral valvular (non-MARM) AF was proposed to exclude patients with valvular heart disease (VHD) without contraindications for NOACs. We aimed to review the efficacy and safety of NOACs in patients with AF and VHD compared to Vitamin K Antagonists (VKA). METHODS: A systematic review with meta-analysis (PROSPERO CRD42015024837) including data from randomized controlled trials (RCTs) retrieved in November 2016...

Tricuspid regurgitation (TR) is a very frequent manifestation of valvular heart disease. It may be due to the primary involvement of the valve or secondary to pulmonary hypertension or to the left-sided heart valve disease (most commonly rheumatic and involving the mitral valve). The pathophysiology of secondary TR is complex and is intrinsically connected to the anatomy and function of the right ventricle. A systematic multimodality approach to diagnosis and assessment (based not only on the severity of the TR but also on the assessment of annular size, RV function and degree of pulmonary hypertension) is, therefore, essential...
