A Global Systematic Review of Open Heart Valvular Surgery in Resource-Limited Settings.

BACKGROUND: Many obstacles challenge the establishment and expansion of cardiac surgery in low- and middle-income countries, despite the unmet cardiac surgical needs. One challenge has been providing adequate follow-up care to monitor anticoagulation, manage morbidity, and prevent mortality. This systematic review describes outcomes after valvular cardiac surgery and focuses on strategies for prolonged follow-up care in resource-constrained settings. METHODS: Studies published between 2012 and 2022 were collected from Embase and the Cochrane Library. Article inclusion criteria were adolescent and adult patients, open heart valvular surgery, and analysis of at least 1 postoperative outcome at least 30 days postoperatively. Studies that focused on pediatric patients, pregnant patients, transcatheter procedures, in-hospital outcomes, and nonvalvular surgical procedures were excluded. Descriptive statistics were assessed, and articles were summarized after abstract screening, full-text review, and data extraction. RESULTS: Sixty-seven relevant publications were identified after screening. The most commonly studied regions were Asia (46%), Africa (36%), and Latin America (9%). Rheumatic heart disease was the most commonly studied valvular disease (70%). Reported outcomes included mortality, surgical reintervention, and thrombotic events. Follow-up duration ranged from 30 days to 144 months; 11 studies reported a follow-up length of 12 months. CONCLUSIONS: Addressing the unmet cardiac care needs requires a multifaceted approach that leverages telemedicine technology, enhances medical infrastructure, and aligns advocacy efforts. Learning from the cost-effective establishment of cardiac surgery in low- and middle-income countries, we can apply past innovations to foster sustainable cardiac surgical capacity.

Recommendations for developing effective and safe paediatric and congenital heart disease services in low-income and middle-income countries: a public health framework.

The global burden of paediatric and congenital heart disease (PCHD) is substantial. We propose a novel public health framework with recommendations for developing effective and safe PCHD services in low-income and middle-income countries (LMICs). This framework was created by the Global Initiative for Children's Surgery Cardiac Surgery working group in collaboration with a group of international rexperts in providing paediatric and congenital cardiac care to patients with CHD and rheumatic heart disease (RHD) in LMICs. Effective and safe PCHD care is inaccessible to many, and there is no consensus on the best approaches to provide meaningful access in resource-limited settings, where it is often needed the most. Considering the high inequity in access to care for CHD and RHD, we aimed to create an actionable framework for health practitioners, policy makers and patients that supports treatment and prevention. It was formulated based on rigorous evaluation of available guidelines and standards of care and builds on a consensus process about the competencies needed at each step of the care continuum. We recommend a tier-based framework for PCHD care integrated within existing health systems. Each level of care is expected to meet minimum benchmarks and ensure high-quality and family centred care. We propose that cardiac surgery capabilities should only be developed at the more advanced levels on hospitals that have an established foundation of cardiology and cardiac surgery services, including screening, diagnostics, inpatient and outpatient care, postoperative care and cardiac catheterisation. This approach requires a quality control system and close collaboration between the different levels of care to facilitate the journey and care of every child with heart disease. This effort was designed to guide readers and leaders in taking action, strengthening capacity, evaluating impact, advancing policy and engaging in partnerships to guide facilities providing PCHD care in LMICs.

Ten-year clinical experience of humanitarian cardiothoracic surgery in Rwanda: Building a platform for ultimate sustainability in a resource-limited setting.

OBJECTIVE: Despite its near complete eradication in resource-rich countries, rheumatic heart disease remains the most common acquired cardiovascular disease in sub-Saharan Africa. With a ratio of physicians/population of 1 per 10,500, including only 4 cardiologists for a population of 11.4 million, Rwanda represents a resource-limited setting lacking the local capacity to detect and treat early cases of strep throat and perform lifesaving operations for advanced rheumatic heart disease. Humanitarian surgical outreach in this region can improve the delivery of cardiovascular care by providing sustainability through mentorship, medical expertise, training, and knowledge transfer, and ultimately the creation of a cardiac center. METHODS: We describe the experience of consecutive annual visits to Rwanda since 2008 and report the outcomes of a collaborative approach to enable sustainable cardiac surgery in the region. The Ferrans and Powers Quality of Life Index tool's Cardiac Version (http://www.uic.edu/orgs/qli/) was administered to assess the postoperative quality of life. RESULTS: Ten visits have been completed, performing 149 open procedures, including 200 valve implantations, New York Heart Association class III or IV, with 4.7% 30-day mortality. All procedures were performed with the participation of local Rwandan personnel, expatriate physicians, nurses, residents, and support staff. Early complications included cerebrovascular accident (n = 4), hemorrhage requiring reoperation (n = 6), and death (n = 7). Quality of life was assessed to further understand challenges encountered after cardiac surgery in this resource-limited setting. Four major domains were considered: health and functioning, social and economic, psychologic/spiritual, and family. The mean total quality of life index was 20.79 ± 4.07 on a scale from 0 to 30, for which higher scores indicated higher quality of life. Women had significantly lower "social and economic" subscores (16.81 ± 4.17) than men (18.64 ± 4.10) (P < .05). Patients who reported receiving their follow-up care in rural health centers also had significantly lower "social and economic" subscores (15.67 ± 3.81) when compared with those receiving follow-up care in urban health facilities (18.28 ± 4.16) (P < .005). Value afforded to family and psychologic factors remained high among all groups. Major postsurgical challenges faced included barriers to follow-up and systemic anticoagulation. CONCLUSIONS: This report represents the first account of a long-term humanitarian effort to develop sustainability in cardiac surgery in a resource-limited setting, Rwanda. With the use of volunteer teams to deliver care, transfer knowledge, and mentor local personnel, the results demonstrate superior outcomes and favorable indices of quality of life. The credibility gained over a decade of effort has created the opportunity for a partnership with Rwanda to establish a dedicated center of cardiac care to assist in mitigating the burden of cardiovascular disease throughout sub-Saharan Africa.
