Case ReportsLate pulmonary valve replacement in congenital heart disease patients without original congenital pulmonary valve pathology.
Many congenital heart defects with pulmonary valve pathology are repaired or palliated in childhood. It is anticipated that these patients will need subsequent pulmonary valve replacement due to the pulmonary regurgitation or right ventricular dilation/failure that results from their original operation. Interestingly, some patients with prior congenital heart surgery and no congenital pulmonary valve pathology require pulmonary valve replacement in adulthood. ⋯ Patients who have undergone previous PA manipulation, regardless whether congenital pulmonary pathology is present, may be at risk for pulmonary valve replacement in adulthood. This report describes five cases of patients with a history of congenital heart surgery but no congenital pulmonary valve pathology who required pulmonary valve replacement due to the consequences of prolonged pulmonary regurgitation. Although pulmonary regurgitation may be well tolerated for many years, it is further evidence for the importance of close follow-up assessment and monitoring of young adults with congenital heart disease.

Bullet embolus is a rare complication of penetrating missile trauma. Removal of the bullet previously required surgery. We report the case of a 14-year-old with an hepatic vein bullet embolus following a gunshot wound to the left buttock. A transjugular approach was used to extract the bullet percutaneously with an Amplatzer gooseneck snare.

Staged surgical approach in neonates with a functionally single ventricle and arch obstruction: pulmonary artery banding and aortic arch reconstruction before placement of a bidirectional cavopulmonary shunt in infants.
The success rate of right-heart bypass surgery in patients with a functionally single ventricle (f-SV) and systemic obstruction is low. In patients with a high risk of subaortic stenosis, we performed an initial step of pulmonary artery banding (PAB) and arch reconstruction before placing a bidirectional cavopulmonary shunt (BCPS) in infants with or without Damus-Kaye-Stansel (DKS) anastomosis. We assessed the success of right-heart bypass surgery. ⋯ DKS anastomosis was performed concomitantly during BCPS placement in 11 infants in whom subaortic stenosis was morphologically suspected but not demonstrated physiologically. As our first-stage operation, arch reconstruction plus PAB provided high success rates for right-heart bypass operations. This strategy is not leading, but it is a reliable approach for progression along a Fontan pathway.

Multicenter StudyStratification of complexity improves the utility and accuracy of outcomes analysis in a Multi-Institutional Congenital Heart Surgery Database: Application of the Risk Adjustment in Congenital Heart Surgery (RACHS-1) and Aristotle Systems in the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database.
Quality-of-care evaluation must take into account variations in "ase mix."This study reviewed the application of two case-mix complexity-adjustment tools in the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database: the Aristotle Basic Complexity (ABC) score and the Risk Adjustment in Congenital Heart Surgery (RACHS-1) method. The 2006 STS Congenital Heart Surgery Database Report, the first STS report to incorporate both methods, included 45,635 operations from 47 centers. Each operation was assigned an ABC score in a range from 1.5 (lowest complexity) to 15 (highest complexity), an ABC level in a range from 1 (lowest complexity) to 4 (highest complexity), and a RACHS-1 category in a range from 1 (lowest risk) to 6 (highest risk). ⋯ The ABC approach allows classification of more operations, whereas the RACHS-1 discriminates better at the higher end of complexity. Complexity stratification is a useful method for analyzing the impact of case mix on pediatric cardiac surgical outcomes. Both the RACHS-1 and ABC methods facilitate complexity stratification in the STS database.

Case ReportsStenting of ductus arteriosus in a neonate with truncus arteriosus and interrupted aortic arch associated with a right aortic arch.
This report describes a case in which successful stenting of ductus arteriosus (DA) was performed for a 27-day-old boy with truncus arteriosus (TA) and interrupted aortic arch (IAA). The patent DA was associated with a right aortic arch. ⋯ Additionally, the DA was longer than in previously reported cases with left aortic arch, thus requiring a longer stent. This experience suggests that DA stenting in neonates with TA and IAA averts surgical repair during the early neonatal period.
