Although 80% of the burden of cardiovascular disorders fall in low- and middleincome countries, poor countries have a very limited capacity to build a system of care to address heart disease, including prevention, care, control and research. In this article, authors who work in or with Rwanda’s public sector aim to describe the current state of heart disease among children, what is currently being done to manage care and future directions for the national programme. As the world turns its attention to non-communicable diseases and seeks to ensure that they fi nd a prominent place in the post-2015 development agenda, it is essential to ensure that children are not left behind.

Here, we perform the first state-of-the-art review of cardiac surgical care in LMICs to highlight the important milestones and current progress, as well as challenges associated with the expansion of sustainable global cardiac surgery for those in need. METHODS A literature review was performed searching the PubMed/MEDLINE and Google Scholar databases using a combination of cardiac surgery, global health, and LMIC keywords. The Institute for Health Metrics and Evaluation Global Burden of Disease Results Tool was used to assess the global burden of disease related to cardiovascular surgical diseases. RESULTS High-income countries are estimated to have over hundred times as many cardiac surgeons per million population compared to low-income countries. There are over 4,000 cardiac centers worldwide, but less than one center per ten million population in LMICs. Approximately 1.5 million cardiac operations are performed globally, of which a disproportionally low number in LMICs. Despite the high costs associated with cardiac operations, recent data suggests the favorable cost-effectiveness thereof in LMICs. Opportunities arise to sustainably integrate cardiac surgery in holistic health systems strengthening interventions. CONCLUSIONS Skepticism underlying the need, feasibility, and cost-effectiveness of cardiac surgery in LMICs prevail, but recent advances, successful case studies, and existing data illustrate the potential of expanding cardiac care globally.

Cardiovascular disease (CVD) remains the number one cause of death among NCDs across the globe. The current review provides insight regarding this disease burden and highlights challenges as well as strategies for establishing functional cardiac surgery centers and sustainable access to comprehensive cardiovascular care within LMICs. Recent Findings Without effective prevention and treatment strategies, estimates suggest that deaths from CVDs will reach 24 million by the year 2030. Surgery exists as a limited option for selected patients with advanced cardiac disease in LMICs in comparison with its availability in developed countries. Summary Multi-lateral or public-private initiatives, government investment, philanthropic efforts, innovative financing systems to strengthen Universal Health Coverage, and expansion of training options through centers of excellence appear to be the way forward to broadening the availability of cardiovascular services, inclusive of surgery, to LMICs.

The most common causes include cardiovascular diseases, cancer, respiratory diseases, and diabetes mellitus. Many adults with acquired cardiothoracic disease around the world have limited access to health care. In addition, congenital heart disease is present in approximately 1% of live births and is therefore the most common congenital abnormality. More than one million children in the world are born with congenital heart disease each year, and approximately 90% of these children receive suboptimal care or have no access to care. Furthermore, many children affected by noncongenital cardiac conditions also require prevention, diagnosis, and treatment. Medical and surgical volunteerism can help facilitate improvement in cardiothoracic health care in developing countries. As we move into the future, it is essential for physicians and surgeons to be act...

Although there is increasing momentum to expand training opportunities in low-resource settings among academic surgical programs, most focus solely on establishing short-term elective rotations rather than fostering research or career development. Given the complex nature of surgical care delivery and programmatic capacity building in the resource-poor settings, many challenges remain before global surgery is accepted as an academic discipline and an established career path. Brigham and Women's Hospital has established a specialized global surgery track within the general surgery residency program to develop academic leaders in this growing area of need and opportunity. Here we describe our experience with the design and development of the program followed by practical applications and lessons learned from our early experiences.

Gene therapy holds tremendous promise as both a practical and translatable technology platform. Its effectiveness is evidenced by the improvements in cardiac function observed in vector-mediated therapeutic transgene delivery to the murine myocardium. A large animal model validating these results is the likely segue into clinical application. However, controversy still exists regarding a suitable method of vector-mediated cardiac gene delivery that provides for efficient, global gene transfer to the large animal myocardium that is also clinically translatable and practical. Intramyocardial injection and catheter-based coronary delivery techniques are attractive alternatives with respect to their clinical applicability; yet, they are fraught with numerous challenges, including concerns regarding collateral gene expression in other organs, low efficiency of vector delivery to the myocardium, inhomogeneous expression, and untoward immune response secondary to gene delivery. Cardiopulmonary bypass (CPB) delivery with dual systemic and isolated cardiac circuitry precludes these drawbacks and has the added advantage of allowing for control of the pharmacological milieu, multiple pass recirculation through the coronary circulation, the selective addition of endothelial permeabilizing agents, and an increase in vector residence time. Collectively, these mechanics significantly improve the efficiency of global, vector-mediated cardiac gene delivery to the large animal myocardium, highlighting a potential therapeutic strategy to be extended to some heart failure patients.

Few regions in sub-Saharan Africa have independently created an effective strategy to detect and treat streptococcal infection and mitigate its progression to RHD. We describe a unique collaboration, where the Rwanda Ministry of Health, the Rwanda Heart Foundation, and an expatriate humanitarian cardiac surgery program have together leveraged an innovative partnership as a means to expand Rwanda's current capacity to address screening and primary prevention, as well as provide life-saving cardiac surgery for patients with critical RHD. Interviews with key personnel and review of administrative records were conducted to obtain qualitative and quantitative data on the recruitment of clinical personnel, procurement of equipment, and program finances. The number of surgical cases completed and the resultant clinical outcomes are reviewed. From 2008 to 2013, six annual visits were completed. A total of 128 prosthetic valves have been implanted in 86 complex patients in New York Heart Association (NYHA) class III or IV heart failure, with excellent clinical outcomes (5 % 30-day mortality). Postoperative complications included a cerebrovascular accident (n = 1) and hemorrhage, requiring reoperation (n = 2). All procedures were performed with participation of local personnel. This strategy provides a reliable and consistent model of sophisticated specialty care delivery; inclusive of patient-centered cardiac surgery, mentorship, didactics, skill transfer, and investment in a sustainable cardiac program to address critical RHD in sub-Saharan Africa.
