Sub-Saharan Africa (SSA), home to over 1 billion people, has only one paediatric otolaryngology fellowship program and nine fellowship-trained paediatric Otolaryngology Head and Neck Surgery (OHNS) specialists covering seven countries. Seven of these specialists estimated an average of 40+ patients per month are in need of critical surgical airway management in their respective countries and that 2–25 deaths per year (mainly paediatric) occur in their country from lack of access to foreign body removal equipment. Investing in paediatric airway infrastructure and capacity would largely benefit the health system in SSA, where the current lack of equipment alone leads to unmeasured morbidity and mortality. As a region of the world with the largest paediatric populations, sub-Saharan Africa’s need is all the more pressing given the disproportionately low number of medical specialists, institutions and resources. Collaborative approaches in procurement and maintenance of high-quality, cost-effective equipment are crucially desirable factors in both low- and middle-income countries (LMICs) and high-income countries (HICs). We, as the Global OHNS Initiative, urge for multi-stakeholder engagement and collaboration to forge lasting change.

BACKGROUND: There are limited data about changes in cardiac function (cardiac reverse remodeling) and heart failure indices after transcatheter tricuspid valve-in-valve replacement (TT-VIVR). The purpose of this study was to evaluate cardiac reverse remodeling and temporal changes in heart failure indices after TT-VIVR in adults with congenital heart disease. METHODS: Retrospective cohort study of adults with congenital heart disease that underwent TT-VIVR and had >6 months of follow-up (January 1, 2011, to April 30, 2023). Echocardiographic indices of cardiac remodeling and heart failure indices (New York Heart Association class, NT-proBNP (N-terminal pro-brain natriuretic peptide), glomerular filtration rate, and model for end-stage liver disease excluding international normalized ratio score) were assessed preintervention and at 1-, 3-, and 5-year postintervention. RESULTS: Of 39 patients (age 39 [32–46] years), 14 (36%) and 25 (64%) received Melody valve and Sapien valve prosthesis, respectively. At 1-year post-TT-VIVR, there was a temporal improvement in right atrial reservoir strain (17±8% versus 22±8%, P <0.001), right atrial volume (81 [59–108] versus 63 [48–82] mL/m 2 , P <0.001), right atrial pressure (12±4% versus 6±4%, P <0.001), and right ventricular global longitudinal strain (−15±7% versus −20±7%, P <0.001). Similarly, there was a temporal improvement in NT-proBNP, glomerular filtration rate, model for end-stage liver disease excluding international normalized ratio score, and New York Heart Association class. The temporal improvements in heart failure indices and valve function were maintained at 3- and 5-year post-TT-VIVR. CONCLUSIONS: Considering the significant mortality risk associated with reoperations for tricuspid valve replacement, these data suggest favorable outcomes after TT-VIVR, and support TT-VIVR as a viable alternative to surgical tricuspid valve replacement, especially in high-risk patients.
