Reintervention and mortality risk after total anomalous pulmonary venous connection repair.

BACKGROUND: Management of total anomalous pulmonary venous connections has been extensively studied to further improve outcomes. Our institution previously reported factors associated with mortality, recurrent obstruction, and reintervention. The study purpose was to revisit the cohort of patients and evaluate factors associated with reintervention, and mortality in early and late follow-up. METHODS: A retrospective review at our institution identified 81 patients undergoing total anomalous pulmonary venous connection repair from January 2002 to January 2018. Demographic and operative variables were evaluated. Anastomotic reintervention (interventional or surgical) and/or mortality were primary endpoints. RESULTS: Eighty-one patients met the study criteria. Follow-up ranged from 0 to 6,291 days (17.2 years), a mean of 1263 days (3.5 years). Surgical mortality was 16.1% and reintervention rates were 19.8%. In re-interventions performed, 80% occurred within 1.2 years, while 94% of mortalities were within 4.1 months. Increasing cardiopulmonary bypass times (p = 0.0001) and the presence of obstruction at the time of surgery (p = 0.025) were predictors of mortality, while intracardiac total anomalous pulmonary venous connection type (p = 0.033) was protective. Risk of reintervention was higher with increasing cardiopulmonary bypass times (p = 0.015), single ventricle anatomy (p = 0.02), and a post-repair gradient >2 mmHg on transesophageal echocardiogram (p = 0.009). CONCLUSIONS: Evaluation of a larger cohort with longer follow-up demonstrated the relationship of anatomic complexity and symptoms at presentation to increased mortality risk after total anomalous pulmonary venous connection repair. The presence of a single ventricle or a post-operative confluence gradient >2 mmHg were risk factors for reintervention. These findings support those found in our initial study.

Gastrostomy Tube Placement in Neonates Undergoing Congenital Heart Surgery: A Novel Assessment for Improving Utilization and Timing of Placement.

BACKGROUND: Neonates undergoing congenital heart defect repair require optimized nutritional support in the perioperative period. Utilization of a gastrostomy tube is not infrequent, yet optimal timing for placement is ill-defined. The objective of this study was to identify characteristics of patients whose postoperative course included gastrostomy tube placement to facilitate supplemental tube feeding following neonatal repair of congenital heart defects. METHODS: A single-institution, retrospective chart review identified 64 consecutive neonates who underwent cardiac operations from 2012 to 2016. Perioperative variables were evaluated for significance in relation to gastrostomy tube placement. RESULTS: A total of 27 (42%) underwent gastrostomy tube placement. Diagnosis of a genetic syndrome was associated with the likelihood of placement of gastrostomy tube (P = .032), as were patients with single ventricle physiology (P = .0013) compared to those felt to be amenable to eventual biventricular repair. Aortic arch reconstruction (P = .029), as well as the need for delayed sternal closure (P = .05), was associated with increased frequency of gastrostomy tube placement. Postoperative outcomes including the number of days intubated (P = .0026) and the presence of significant dysphagia (P = .0034) were associated with gastrostomy placement. Additionally, genetic syndrome (P = .003), aortic arch reconstruction (P = .01), and postoperative intubation duration (P = .0024) correlated with increased length of stay, where increased length of stay was associated with gastrostomy tube placement (P = .0004). DISCUSSION: Patient characteristics that were associated with a high likelihood of eventual gastrostomy placement were identified in this study. Early recognition of such characteristics in future patients may allow for reduced time to gastrostomy tube placement, which in turn may improve perioperative growth and outcomes.

Novel Annular and Subvalvular Enlargement in Congenital Mitral Valve Replacement.

Reparative procedures are not always feasible in congenitally abnormal mitral valves. Mechanical prosthesis has been accepted as the choice for valve replacement in the pediatric population. This report describes a case of congenital mitral valve disease requiring mitral valve replacement. The infant's mitral valve annulus was not amenable to placement of the smallest available mechanical prosthesis. The approach used here for annular and subvalvular enlargement facilitated implantation of a larger prosthesis for congenital mitral valve replacement. Five-year outcomes in a single patient may indicate broader applicability and avoidance of patient-prosthesis mismatch.
