Background Use of the expanded polytetrafluoroethylene (ePTFE) valved conduit in the pulmonary position during the correction of congenital heart defects has significantly increased in popularity over the last decade due to its promising conduit longevity. We describe the standardized process to create and implant a trileaflet ePTFE pulmonary conduit along with the early outcomes of such procedures at our institute. Methods Records of 100 consecutive patients who underwent ePTFE valved conduit placement using our technique from April 2018 through February 2022 were retrospectively analyzed. The function of the conduit was evaluated by transthoracic echocardiography. Results The mean age of the patients was 28 ± 13.2 years old at the time of the operation. The conduit diameters ranged from 16 to 24 mm (mean 23.0 ± 1.9 mm). Conduit placement was utilized for pulmonary valve replacement in 68 patients, conduit change in 25 patients, and as a part of total repair in 7 patients. There were 2 in-hospital conduit-unrelated deaths from multi-organ dysfunction and pulmonary hypertensive crisis. From the postoperative echocardiography, the average peak pressure gradient across the conduit was 18.6 ± 9.0 mm Hg, and the conduit regurgitation was graded as none or trace in 81 patients, mild in 17 patients, and moderate in 2 patients. At 589 days of median follow-up, there was no conduit reoperation. Follow-up imaging of 60 available patients at a median time of 511 days did not show a significant change in conduit function. Conclusions Our standardized ePTFE valved conduit creation and placement demonstrated satisfactory clinical and echocardiographic outcomes.
Background: The modified Fontan procedure has routinely been performed in children in the present study hospital. Recently, some adults with functionally univentricular hearts were potential candidates for a Fontan completion. Objective: To review the early results of the single stage Fontan procedure in three adult patients in the last two years. Case Report: There was no mortality. Re-operations were observed in two patients. The mean extubation time, ICU stay, and hospital stay were three days, five days, and ten days, respectively. The median post-operative oxygenation was 95%. The NYHA class improved significantly in all patients. Conclusion: Single stage Fontan completion can be performed in carefully selected adult patients. The present report is the early results in three consecutive patients over the last two years. The long-term outcome needs to be followed. The authors hope to enroll more adult patients with univentricular heart and to determine the criteria for a potential adult candidate in the future.

Background Postoperative infection contributes to the worsening of congenital cardiac surgery (CCS) outcomes. Surgical site infection (SSI), bloodstream infection (BSI) and ventilator associated pneumonia (VAP) are common. An additional bundle of preventive measures against central-line associated bloodstream infection (CLABSI) bundle was implemented in April 2019. Objectives To compare the incidence of major infections after pediatric CCS before and after the implementation of the CLABSI bundle and to identify risk factors for major infections. Methods We conducted a single-center, retrospective study to assess the incidence of major infections including bloodstream infection (BSI), surgical site infection (SSI), and ventilator-associated pneumonia (VAP) after pediatric CCS one year before and after implementation of the CLABSI bundle during April 2018–March 2020. The demographics and outcomes of the patients were explored, and risk factors for major infections were identified using multivariate analysis. Results A total of 548 children (53% male) underwent CCS with a median age of 1.9 years (range 0.01–17.5 years). The median Aristotle Basic Complexity score was 7.1 (range 3–14.5). The CLABSI bundle was applied in 262 patients. Overall mortality was 5.5%. 126 patients (23%) experienced major postoperative infections. During the year after the implementation of the CLABSI bundle, BSI was reduced from 8.4% to 3.1% (p = 0.01), with a smaller reduction in VAP (21% to 17.6%; p = 0.33). The incidence of SSI was unchanged (1.7% to 1.9%; p = 0.77). The independent risk factors for major infections were age at surgery <6 months (p = 0.04), postoperative ventilator usage >2 days (p < 0.01), central line usage >4 days (p = 0.04), and surgery during the pre-CLABSI bundle period (p = 0.01). Conclusion Following the implementation of the CLABSI prevention package in our pediatric CCS unit, the incidence of BSI was significantly reduced. The incidence of VAP tended to decrease, while the SSI was unchanged. Sustainability of the prevention package through nurse empowerment and compliance audits is an ongoing challenge.
