“…Using data from hospital members of the Child Health Corporation of America, Checchia PA et al 14 studied 1105 newborns from 1988 to 2001 admitted with the diagnosis of HLHS, and observed that 801 had undergone the Norwood procedure, 39 heart transplantation, and the remaining 265 (24%) did not undergo surgical intervention. …”

SummaryObjectives: To report a surgical strategy for the Norwood procedure in the hypoplastic left heart syndrome (HLHS) that enables short hypothermic circulatory arrest time and aortic arch reconstruction with autologous pericardium patch, and to compare the results of the modified Blalock- Taussig Results: In-hospital survival for the entire cohort was 74.64%, or 67.57% and 82.35% for the mBT shunt and RV-PA conduit groups, respectively (p=0.1808). Mortality rates between the first and second palliation stages were 40% and 4.4% for the mBT shunt and RV-PA conduit groups, respectively (p=0.0054). Hypothermic circulatory arrest times were 45.79±1.99 min and 36.62±1.62min (p=0.0012), respectively. Late coarctation of the aorta occurred in five patients (7.2%).Conclusions: This surgical strategy resulted in short circulatory arrest time, low mortality and favorable morphology of the neoaorta, with low incidence of late coarctation of the aorta. The higher rate of survival to first palliation stage with the RV-PA conduit was not significant, but interstage mortality was statistically lower when compared with the modified Blalock-Taussig shunt procedure.

“…Traditionally, research has shown an association between low case volume and poor outcomes in a multitude of surgical procedures, [1][2][3][4][5] such as hysterectomy, 6 pancreatectomy, 5,7 esophagectomy, 5 pelvic exenteration, 5 and coronary artery bypass surgery. 2,8,9 Studies have also shown this relationship in several pediatric procedures of varying complexity, such as cardiac surgery, 10,11 pyloromyotomy, 12 appendectomy, 13,14 and inguinal hernia repairs. 13,14 In the field of transplantation, a landmark manuscript published in 1999 suggested that programs performing ,20 transplants per year had inferior outcomes.…”

“…Pediatrics 2012;129:e370-e376 Several previous studies have documented a relationship between center volume and outcome in children undergoing a variety of surgical procedures including liver transplant, appendectomy, pyloromyotomy, and heart surgery. [1][2][3][4][5][6][7][8][9][10] In children undergoing heart surgery, it has been shown that higher surgical volume is associated with improved survival, particularly for high risk surgeries. 1 However, there are limited data regarding factors that may mediate this volume-outcome relationship, and may thus be targeted for quality improvement.…”

WHAT'S KNOWN ON THIS SUBJECT: Previous analyses have suggested that center volume is associated with outcome in children undergoing heart surgery. There are limited data regarding factors that may mediate this volume-outcome relationship. WHAT THIS STUDY ADDS:A multicenter analysis of 35 776 children revealed that the higher mortality observed at lower volume centers may be related to a higher rate of mortality in those with postoperative complications, rather than a higher rate of complications alone. abstract OBJECTIVE: Previous analyses have suggested center volume is associated with outcome in children undergoing heart surgery. However, data are limited regarding potential mediating factors, including the relationship of center volume with postoperative complications and mortality in those who suffer a complication. We examined this association in a large multicenter cohort.METHODS: Children 0 to 18 years undergoing heart surgery at centers participating in the Society of Thoracic Surgeons Congenital Heart Surgery Database (2006Database ( -2009 were included. In multivariable analysis, we evaluated outcomes associated with annual center volume, adjusting for patient factors and surgical risk category.RESULTS: A total of 35 776 patients (68 centers) were included. Overall, 40.6% of patients had $1 complication, and the in-hospital mortality rate was 3.9%. The mortality rate in those patients with a complication was 9.0%. In multivariable analysis, lower center volume was significantly associated with higher in-hospital mortality. There was no association of center volume with the rate of postoperative complications, but lower center volume was significantly associated with higher mortality in those with a complication (P = .03 when volume examined as a continuous variable; odds ratio in centers with ,150 vs .350 cases per year = 1.59 [95% confidence interval: 1.16-2.18]). This association was most prominent in the higher surgical risk categories.CONCLUSIONS: These data suggest that the higher mortality observed at lower volume centers in children undergoing heart surgery may be related to a higher rate of mortality in those with postoperative complications, rather than a higher rate of complications alone.
