This is in part due to lack of infrastructures, financial means, and expertise. As a result, patients undergo surgery much later than in high-income countries. This delay in treatment results in right ventricular dysfunction, cardiac arrhythmias, and poor psychomotor development-complications that are all related to chronic hypoxia. There are limited data and a few small studies of patients treated for tetralogy of Fallot in LMICs, and, therefore, the aim of this review is to analyse and summarize the surgical outcomes of this LMIC population.© 2023 The Author(s).DibNabilNDivision of Pediatric Cardiac Surgery, Centre Hospitalier Universitaire Ste-Justine, Université de Montréal, Montréal, Québec, Canada.ChauvetteVincentVDivision of Pediatric Cardiac Surgery, Centre Hospitalier Universitaire Ste-Justine, Université de Montréal, Montréal, Québec, Canada.DiopMomar SokhnaMSThoracic and Cardiovascular Surgery Department, CHU Fann, Dakar, Senegal.BouhoutIsmailIDivision of Pediatric Cardiac Surgery, Centre Hospitalier Universitaire Ste-Justine, Université de Montréal, Montréal, Québec, Canada.HadidMehdiMDivision of Pediatric Cardiology, Centre Hospitalier Universitaire Ste-Justine, Université de Montréal, Montréal, Québec, Canada.VôChristopheCDivision of Pediatric Cardiology, Centre Hospitalier Universitaire Ste-Justine, Université de Montréal, Montréal, Québec, Canada.KhairyPaulPDivision of Pediatric Cardiology, Centre Hospitalier Universitaire Ste-Justine, Université de Montréal, Montréal, Québec, Canada.Electrophysiology Service, Montreal Heart Institute, Université de Montréal, Montréal, Québec, Canada.PoirierNancyNDivision of Pediatric Cardiac Surgery, Centre Hospitalier Universitaire Ste-Justine, Université de Montréal, Montréal, Québec, Canada.engJournal ArticleReview20231222
United StatesCJC Pediatr Congenit Heart Dis99186973646066762772-8129Dans les pays à revenu faible ou intermédiaire (PRFI), les ressources sont limitées pour diagnostiquer et prendre en charge les cardiopathies congénitales comme la tétralogie de Fallot. Cette situation est attribuable en partie au manque d’infrastructures, de moyens financiers et d’expertise. Les patients subissent donc une correction chirurgicale beaucoup plus tard que dans les pays à revenu élevé. Les délais de traitement peuvent entraîner une dysfonction ventriculaire droite, une arythmie cardiaque et des problèmes de développement psychomoteur : des complications toutes liées à l’hypoxie chronique. Il existe des données limitées et quelques études de faible envergure sur des patients traités pour une tétralogie de Fallot dans les PRFI. L’objectif du présent article de synthèse est donc d’analyser et de résumer les issues des interventions chirurgicales dans les PRFI pour cette population.© 2023 The Author(s).2023828202312920245226432024522642202452234920231222epublish38774683PMC1110303310.1016/j.cjcpc.2023.12.002S2772-8129(23)00201-4Murphy J.G., Gersh B.J., Mair D.D., et al.
