Mobile interventions provide a sophisticated yet simple tool to improve perioperative healthcare. Future considerations to address include usage fatigue and Health Insurance Portability and Accountability Act compliance concerns.
Background: Bidirectional Glenn shunt (BDG) failure carries high morbidity and mortality but the clinical factors associated with failure and the optimal management strategy are understudied. Methods: A total of 217 patients undergoing BDG at our institution between 1989 and 2020 were retrospectively reviewed and categorized as success or failure. Failure was defined as the need for reoperation (BDG takedown, reoperation for correction of cardiac defect, and/or transplantation) at any time postoperatively; operative mortality (death attributable to BDG malfunction occurring during the index hospitalization for BDG or within 30 days of discharge); or late mortality (death directly attributable to BDG malfunction occurring prior to Fontan or next-stage palliation). Univariate and binary logistic regression analyses were performed. Results: BDG failure occurred in 14 (6.5%) patients. Univariate predictors were: hypoplastic left heart syndrome ( P = .037), right ventricular (RV) dominance ( P = .010), greater pre-BDG pulmonary vascular resistance (PVR) ( P = .012), concomitant atrioventricular valve repair ( P = .020), prolonged pleural drainage ( P = .001), intensive care unit ( P<.001) and hospital ( P = .002) stays, and extracorporeal membrane oxygenation (ECMO) requirement ( P<.001). Multivariate predictors were: RV dominance ( P = .002), greater PVR ( P = .041), ICU ( P<.001) and hospital ( P = .020) stays, and need for ECMO ( P<.001). As many as 10 of 14 (71%) patients with BDG failure died. Reoperation was performed for 10 patients with BDG failure. Five reoperation patients survived until discharge, with four patients alive at last follow-up (mean 7.9 years). Survivors underwent reoperation earlier than nonsurvivors (36 vs. 94 days). Conclusions: BDG failure carries high mortality, but preoperative predictors and postoperative indicators of failure exist. Early BDG takedown and insertion of aorta-pulmonary shunt may allow survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
