Multicenter StudyThe Pediatric Heart Failure Workforce: An International, Multicenter Survey.
Our objective was to understand the scope of pediatric heart failure (HF) and the current staffing environment of HF programs. An online survey was distributed to members of the Pediatric Heart Transplant Study and the Pediatric Council of the International Society for Heart and Lung Transplantation. All participants received the primary 23-question survey. ⋯ Advanced practice providers (APP) were utilized in 15 programs, nurse coordinators in 2, and both in 3. Most HF programs are formalized, utilize APP, and have inadequate HF staffing to utilize a separate inpatient HF service. Exposure of general pediatric cardiology fellows to HF care is variable between institutions.

Safety and Efficacy of Radiofrequency Catheter Ablation for Tachyarrhythmia in Children Weighing Less Than 10 kg.
An increasing number of children are undergoing radiofrequency catheter ablation (RFCA) for tachyarrhythmia. However, infants and toddlers undergoing RFCA are often resistant to medication or need to eliminate arrhythmia substrate, and the risks of RFCA complications are still high in infants and toddlers. From April 2008 and December 2016, 285 children who underwent radiofrequency catheter ablation (RFCA) were stratified according to body weight (group A, less than 10 kg, n = 22; group B, over 10 kg, n = 263) and the clinical features of RFCA were retrospectively reviewed in these groups. ⋯ Major complications included complete right bundle branch block in one patient. No significant differences in rates of success, recurrence, or complications were noted between children weighing less and more than 10 kg. RFCA is safe and efficacious for tachyarrhythmia even in patients weighing less than 10 kg.

Long-Term Results of Bilateral Pulmonary Artery Banding Versus Primary Norwood Procedure.
Bilateral pulmonary artery banding (PAB) has emerged to be an attractive option as an initial procedure for the treatment of hypoplastic left heart syndrome (HLHS), and some centers report excellent survival. However, its usage is variable among institutions and its true efficacy is unknown due to reporting biases. We aimed to describe the results of bilateral PAB use, preoperative risk factors, and long-term outcomes compared with primary Norwood procedure, using a national database. ⋯ When the risk-adjusted outcomes were evaluated, there was no significant difference between the primary Norwood group and the bilateral PAB group (76.4 vs. 78.1%, log-rank p = 0.87) in higher volume institutions. The primary Norwood group had better 5-year survival than the bilateral PAB group, but preoperative risk was higher in the bilateral PAB group. Because outcomes are comparable when performed at higher HLHS volume institutions, proper patient selection is important in achieving good long-term result.

Single-Stage Correction for Taussig-Bing Anomaly Associated With Aortic Arch Obstruction.
Taussig-Bing anomaly and aortic arch obstruction are two types of complex congenital cardiac malformations. Almost 50% of patients with Taussig-Bing anomaly have aortic arch obstruction. This report assesses the surgical outcomes of single-stage correction in neonates with both defects. ⋯ All survivors remained in good condition (New York Heart association functional class I or II). Single-stage correction of Taussig-Bing anomaly with aortic arch obstruction in neonates had favorable short- and mid-term outcomes in terms of mobility and reoperation rate. The optimal operative procedure should be chosen according to the position of the coronary arteries and the type of aortic anomaly.

Routine Sildenafil Does Not Improve Clinical Outcomes After Fontan Operation.
Fontan operation can be complicated by persistent chest tube output (CTO) leading to prolonged hospital length of stay (LOS). Postoperative sildenafil administration has been shown to improve clinical outcomes in selected patients after Fontan. We initiated a practice change utilizing intravenous (IV) sildenafil in early postoperative period in all patients undergoing Fontan operation with aim to decrease LOS and CTO. ⋯ There was no mortality. IV sildenafil was well tolerated, and no doses were held. Routine early administration of sildenafil after Fontan operation is not associated with an improvement in any measured clinical outcome, including postoperative CTO, LOS, colloid administration, or duration of mechanical ventilation.
