RESUMO
Double ventricular response (DVR), where a single P wave results in two QRS complexes, is a rare presentation of dual AV node physiology. It has been associated with ventricular dysfunction in the setting of incessant tachycardia. We present the case of an otherwise healthy adolescent who had frequent DVR without tachycardia leading to left ventricular dysfunction. Slow pathway modification led to a significant reduction in ectopy and normalization of ventricular function. This highlights that DVR without tachycardia might lead to ventricular dysfunction in pediatric patients. Slow pathway modification with reduction of ectopy may be sufficient to restore ventricular function.
RESUMO
OBJECTIVE: To assess the variables associated with incomplete and unscheduled cardiology clinic visits among referred children with a focus on equity gaps. STUDY DESIGN: We conducted a retrospective chart review for patients less than 18 years of age who were referred to cardiology clinics at a single quaternary referral centre from 2017 to 2019. We collected patient demographic data including race, an index of neighbourhood socio-economic deprivation linked to a patient's geocoded address, referral information, and cardiology clinic information. The primary outcome was an incomplete clinic visit. The secondary outcome was an unscheduled appointment. Independent associations were identified using multivariable logistic regression. RESULTS: There were 10,610 new referrals; 6954 (66%) completed new cardiology clinic visits. Black race (OR 1.41; 95% CI 1.22-1.63), public insurance (OR 1.29; 95% CI 1.14-1.46), and a higher deprivation index (OR 1.32; 95% CI 1.08-1.61) were associated with higher odds of incomplete visit compared to the respective reference groups of White race, private insurance, and a lower deprivation index. The findings for unscheduled visit were similar. A shorter time elapsed from the initial referral to when the appointment was made was associated with lower odds of incomplete visit (OR 0.62; 95% CI 0.52-0.74). CONCLUSION: Race, insurance type, neighbourhood deprivation, and time from referral date to appointment made were each associated with incomplete referrals to paediatric cardiology. Interventions directed to understand such associations and respond accordingly could help to equitably improve referral completion.
RESUMO
BACKGROUND: This study evaluates tube-specific outcomes after primary placement of low-profile buttons (LPBs) compared with long gastrostomy tubes (LGTs). MATERIALS AND METHODS: All surgically placed gastrostomy tubes from 2015 to 2017 from a single institution were reviewed. Primary outcomes were tube dislodgement and tube-related readmissions within 30 d. Secondary outcomes were resource utilization and minor complications within 6 mo. RESULTS: 53% (n = 253) of patients received an LGT and 47% (n = 228) received an LPB. Groups were similar with regard to operative indication and approach, but LPB patients were slightly older (9 versus 6 mo, P = 0.02). Tube dislodgement occurred overall in 6% of patients, with 23% and 41% experiencing leakage and granulation tissue, respectively. LGT patients experienced higher rates of tube dislodgement (9% versus 3%, P = 0.006), but no difference in tube-related readmissions (P = 0.38). LGT patients were also more likely to visit the ER for a tube-related concern (43.9% versus 31.6%, P = 0.01) and report problems of leakage around the tube (27.7% versus 17.5%, P = 0.01). No difference was found for issues of peristomal granulation tissue or in tube-related readmissions. CONCLUSIONS: Primary placement of low-profile gastrostomy buttons is safe and demonstrated superior tube-related outcomes compared with LGTs.
