Using reconditioned pacemakers to treat bradycardia in Africa

Advancing global equity in cardiac care as cardiac implantable electronic device reuse comes of age

A nation's health and economic development are inextricably and synergistically connected. Stark differences exist between wealthy and developing nations in the use of cardiac implantable electronic devices (CIEDs). Cardiovascular disease is now the leading cause of death in low- and middle-income countries (LMIC), with a significant burden from rhythm-related diseases. As science, technology, education, and regulatory frameworks have improved, CIED recycling for exportation and reuse in LMIC has become possible and primed for widespread adoption. In our manuscript, we outline the science and regulatory pathways regarding CIED reuse. We propose a pathway to advance this technology that includes creating a task force to establish standards for CIED reuse, leveraging professional organizations in areas of need to foster the professional skills for CIED reuse, collaborating with regulatory agencies to create more efficient regulatory expectations and bring the concept to scale, and establishing a global CIED reuse registry for quality assurance and future science.

Cardiovascular diseases in Africa in the twenty-first century: Gaps and priorities going forward

In 2015, the United Nations set important targets to reduce premature cardiovascular disease (CVD) deaths by 33% by 2030. Africa disproportionately bears the brunt of CVD burden and has one of the highest risks of dying from non-communicable diseases (NCDs) worldwide. There is currently an epidemiological transition on the continent, where NCDs is projected to outpace communicable diseases within the current decade. Unchecked increases in CVD risk factors have contributed to the growing burden of three major CVDs-hypertension, cardiomyopathies, and atherosclerotic diseases- leading to devastating rates of stroke and heart failure. The highest age standardized disability-adjusted life years (DALYs) due to hypertensive heart disease (HHD) were recorded in Africa. The contributory causes of heart failure are changing-whilst HHD and cardiomyopathies still dominate, ischemic heart disease is rapidly becoming a significant contributor, whilst rheumatic heart disease (RHD) has shown a gradual decline. In a continent where health systems are traditionally geared toward addressing communicable diseases, several gaps exist to adequately meet the growing demand imposed by CVDs. Among these, high-quality research to inform interventions, underfunded health systems with high out-of-pocket costs, limited accessibility and affordability of essential medicines, CVD preventive services, and skill shortages. Overall, the African continent progress toward a third reduction in premature mortality come 2030 is lagging behind. More can be done in the arena of effective policy implementation for risk factor reduction and CVD prevention, increasing health financing and focusing on strengthening primary health care services for prevention and treatment of CVDs, whilst ensuring availability and affordability of quality medicines. Further, investing in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on interventions. This review summarizes the current CVD burden, important gaps in cardiovascular medicine in Africa, and further highlights priority areas where efforts could be intensified in the next decade with potential to improve the current rate of progress toward achieving a 33% reduction in CVD mortality.

Battery life of cardiac implantable electronic devices explanted in funeral homes: a potential resource for underserved nations

INTRODUCTION

Cardiac implantable electronic devices (CIEDs) could still have adequate battery life and functionality when they are explanted after the death of the carrier, supposing an important resource for low- and middle- income countries where patients cannot afford new devices.

OBJECTIVE

The aim was to analyse the remaining battery life and reusability of CIEDs recovered from funeral homes.

METHOD

A descriptive study of postmortem explanted CIEDs was conducted. Devices were collected from three funeral homes in the Spanish region of the Basque Country (participation rate 33.3%). Devices with a remaining battery life of >75% or > 4 years, preserved external integrity and no evidence of malfunction were considered reusable.

RESULTS

A total of 188 CIEDs were collected (175 pacemakers and 13 defibrillators). Of the total number of devices, 95 (50.5%) had enough battery to be interrogated. Among the interrogable devices, a total of 20 pacemakers (22.4%) had an estimated battery life of more than 4 years, as well as preserved integrity and no record of malfunction.

CONCLUSIONS

A non-negligible number of postmortem explanted devices had battery life, external integrity and functionality to be considered reusable. Postmortem CIED donation could provide treatment to patients unable to afford new devices.

Spanish Rhythm Association member´s perspectives on cardiac implantable electronic device reuse in low- and middle-income countries

BACKGROUND

Postmortem explanted cardiac implantable electronic devices (CIEDs) from developed countries could provide patients unable to afford new devices in low- and middle-income countries (LMIC) a treatment they lack. This study describes the preferences of electrophysiologists and device implanting cardiologists from Spain on the management of explanted CIEDs and opinions and concerns regarding reuse in LMIC.

METHODS

A nationwide self-administered questionnaire was sent to members of the Spanish Rhythm Association (n = 1110), between December 2020 and January 2021.

RESULTS

Forty-two physician responses were obtained (response rate 5%). There was a strong preference to donate explanted devices for reuse in humans (61.9%) or animals (31%). The vast majority of the participants thought device reutilization was safe, ethical, and a reasonable alternative if a new device is not accessible. Moreover, they indicated they would be comfortable asking patients to consider post-mortem donation, and willing to implant post-mortem explanted and resterilized devices if they were unable to obtain new ones. 57.1% of respondents considered it would be beneficial for patients to have a document so they could reflect their wishes regarding device handling after their death. The most mentioned concerns regarding device reuse were malfunction (57.1%) and infection (54.8%).

CONCLUSIONS

The majority of respondents support reusable CIED donation to LMIC. It would be interesting to study the feasibility of a nationwide device reutilization program.

Reuse of cardiac implantable electronic devices in developing countries perspectives: A literature review

INTRODUCTION AND OBJECTIVES

Access to cardiac implantable electronic devices (CIEDs) is limited in developing countries. Postmortem CIED donation from developed countries to developing countries could be an important resource for those who cannot afford a new one. The objective of this paper was to identify and synthesize the perspectives on the donation of CIEDs for potential reuse in patients without resources living in developing countries.

METHODS

A bibliographic review was carried out in the PubMed, Web of Science and Scopus databases. The search strategy was limited to articles published in English or Spanish.

RESULTS

Eight publications were analyzed. The main results were grouped into two large frameworks on perceptions, preferences, attitudes and opinions of developed countries and developing countries towards the donation and reuse of CIEDs. Positive perspectives were identified towards the donation of CIEDs for their reuse in the majority of patients with a CIED, relatives, funeral homes and physicians of developed countries, as well as in physicians and potential recipient patients of developing countries.

CONCLUSIONS

This review highlights the positive perspectives on CIED donation from developed countries to patients in need of developing countries among all studied groups. In view of the feasibility of collecting postmortem devices, we advocate studying the feasibility of more local CIED donation initiatives.

Cardiac Pacing in Sub-Saharan Africa: JACC International

Many parts of the developing world, especially Sub-Saharan Africa, completely lack access to cardiac pacing. The authors initiated a multinational program to implement cardiac pacing in 14 countries in Sub-Saharan Africa (1996 to 2018), aiming to eventually build self-sustainable capacity in each country. This was based on an "on-site training" approach of performing procedures locally and educating local health care teams to work within resource-limited settings, with prospective evaluation of the program. In 64 missions, a total of 542 permanent pacemakers were implanted. In 11 of these countries, the first pacemaker implant in the country was through the mission. More than one-half of those initially listed as suitable died before the mission(s) arrived. The proportion of implantations that were completely handled by local teams increased from 3% in 1996 to 98% in 2018. These findings demonstrate the feasibility and effectiveness of a proctorship-based approach to the development of local cardiac pacing capabilities in Sub-Saharan African nations.

A Systematic Review of the Spectrum of Cardiac Arrhythmias in Sub-Saharan Africa

Major structural cardiovascular diseases are associated with cardiac arrhythmias, but their full spectrum remains unknown in sub-Saharan Africa (SSA), which we addressed in this systematic review. Atrial fibrillation/atrial flutter (AF/AFL) prevalence is 16-22% in heart failure, 10-28% in rheumatic heart disease, 3-7% in cardiology admissions, but <1% in the general population. Use of oral anticoagulation is heterogenous (9-79%) across SSA. The epidemiology of sudden cardiac arrest/death is less characterized in SSA. Cardiopulmonary resuscitation is challenging, owing to low awareness and lack of equipment for life-support. About 18% of SSA countries have no cardiac implantable electronic devices services, leaving hundreds of millions of people without any access to treatment for advanced bradyarrhythmias, and implant rates are more than 200-fold lower than in the western world. Management of tachyarrhythmias is largely non-invasive (about 80% AF/AFL via rate-controlled strategy only), as electrophysiological study and catheter ablation centers are almost non-existent in most countries.

Highlights

- Atrial fibrillation/flutter prevalence is 16-22% in heart failure, 10-28% in rheumatic heart disease, 3-7% in cardiology admissions, and <1% in the general population in sub-Saharan Africa (SSA).- Rates of oral anticoagulation use for CHA2DS2VASC score ≥2 are very diverse (9-79%) across SSA countries.- Data on sudden cardiac arrest are scant in SSA with low cardiopulmonary resuscitation awareness.- Low rates of cardiac implantable electronic devices insertions and rarity of invasive arrhythmia treatment centers are seen in SSA, relative to the high-income countries.
