Impact of veno-venous collaterals on outcome after the total cavopulmonary connection. Int J Cardiol 2024; 410:132229. [PMID: 38838746 DOI: 10.1016/j.ijcard.2024.132229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Revised: 05/04/2024] [Accepted: 06/03/2024] [Indexed: 06/07/2024]
Abstract
OBJECTIVE To evaluate the prevalence of veno-venous collaterals (VVCs) after total cavopulmonary connection (TCPC) and analyze their impact on outcomes. METHODS Patients undergoing TCPC between 1994 and 2022 were evaluated. VVCs were identified using angiograms of cardiac catheterizations and their impact on outcomes was analyzed. RESULTS A total of 635 patients were included. Median age at TCPC was 2.3 (interquartile ranges (IQR): 1.8-3.3) years. The most frequent diagnosis was hypoplastic left heart syndrome in 173 (27.2%) patients. Prior bidirectional cavopulmonary shunt was performed in 586 (92.3%) patients at a median age of 5.3 (3.6-9.9) months. VVCs were found in 94 (14.8%) patients at a median of 2.8 (0.1-11.8) years postoperatively. The prevalence of VVCs was similar between the dominant right and left ventricle (14.7 vs. 14.9%, p = 0.967). Mean pulmonary artery pressure (16.2 vs. 16.0 mmHg, p = 0.902), left atrial pressure (5.5 vs. 5.7 mmHg, p = 0.480), transpulmonary gradient (4.0 vs. 3.8 mmHg, p = 0.554) and oxygen saturation (81.4 vs. 82.6%, p = 0.103) before TCPC were similar between patients with and without VVCs. The development of VVCs did not affect survival after TCPC (p = 0.161). Nevertheless, VVCs were a risk for the development of plastic bronchitis (PB, p < 0.001). Interventional closure of VVCs was performed in 60 (9.4%) patients at a median of 8.9 (0.6-15.1) years after TCPC, and improvement of oxygen saturation was observed in 66% of the patients. CONCLUSIONS The prevalence of VVCs after TCPC was 15%. VVCs had no impact on survival following TCPC but were associated with a high prevalence of PB.

Abstract
OBJECTIVE The purpose of this study is to evaluate the incidence and outcomes regarding tachyarrhythmia in patients after total cavopulmonary connection. METHODS A retrospective analysis of 620 patients who underwent total cavopulmonary connection between 1994 and 2021 at our institution was performed. Incidence of tachyarrhythmia was depicted, and results after onset of tachyarrhythmia were evaluated. Factors associated with the onset of tachyarrhythmia were identified. RESULTS A total of 52 (8%) patients presented with tachyarrhythmia that required medical therapy. Onset during hospital stay was observed in 27 patients, and onset after hospital discharge was observed in 32 patients. Freedom from late tachyarrhythmia following total cavopulmonary connection at 5, 10, and 15 years was 97, 95, and 91%, respectively. The most prevalent late tachyarrhythmia was atrial flutter (50%), followed by supraventricular tachycardia (25%) and ventricular tachycardia (25%). Direct current cardioversion was required in 12 patients, and 7 patients underwent electrophysiological study. Freedom from Fontan circulatory failure after onset of tachyarrhythmia at 10 and 15 years was 78% and 49%, respectively. Freedom from occurrence of decreased ventricular systolic function after the onset of tachyarrhythmia at 5 years was 85%. Independent factors associated with late tachyarrhythmia were dominant right ventricle (hazard ratio, 2.52, p = 0.02) and weight at total cavopulmonary connection (hazard ratio, 1.03 per kilogram; p = 0.04). Type of total cavopulmonary connection at total cavopulmonary connection was not identified as risk. CONCLUSIONS In our large cohort of 620 patients following total cavopulmonary connection, the incidence of late tachyarrhythmia was low. Patients with dominant right ventricle and late total cavopulmonary connection were at increased risk for late tachyarrhythmia following total cavopulmonary connection.

Abstract
Univentricular heart anomalies represent a group of severe congenital heart defects necessitating early surgical intervention in infancy. The Fontan procedure, the final stage of single-ventricle palliation, establishes a serial connection between systemic and pulmonary circulation by channeling venous return to the lungs. The absence of the subpulmonary ventricle in this peculiar circulation progressively eventuates in failure, primarily due to chronic elevation in inferior vena cava (IVC) pressure. This study experimentally validates the effectiveness of an intracorporeally-powered venous ejector pump (VEP) in reducing IVC pressure in Fontan patients. The VEP exploits a fraction of aortic flow to create a jet-venturi effect for the IVC, negating the external power requirement and driveline infections. An invitro Fontan mock-up circulation loop is developed and the impact of VEP design parameters and physiological conditions is assessed using both idealized and patient-specific total cavopulmonary connection (TCPC) phantoms. The VEP performance in reducing IVC pressure exhibited an inverse relationship with the cardiac output and extra-cardiac conduit (ECC) size and a proportional relationship with the transpulmonary pressure gradient (TPG) and mean arterial pressure (MAP). The ideal VEP with fail-safe features provided an IVC pressure drop of 1.82 ± 0.49, 2.45 ± 0.54, and 3.12 ± 0.43 mm Hg for TPG values of 6, 8, and 10 mm Hg, respectively, averaged over all ECC sizes and cardiac outputs. Furthermore, the arterial oxygen saturation was consistently maintained above 85% during full-assist mode. These results emphasize the potential utility of the VEP to mitigate elevated venous pressure in Fontan patients.

Abstract
BACKGROUND Brady-arrhythmia requiring pacemaker implantation remains one of the Fontan-specific complications before and after total cavopulmonary connection. METHODS A retrospective analysis of 620 patients who underwent total cavopulmonary connection between 1994 and 2021 was performed to evaluate the incidence of brady-arrhythmia and the outcomes after pacemaker implantation. Factors associated with the onset of brady-arrhythmia were identified. RESULTS A total of 52 patients presented with brady-arrhythmia and required pacemaker implantation. Diagnosis included 16 sinus node dysfunctions, 29 atrioventricular blocks, and 7 junctional escape rhythms. Pacemaker implantation was performed before total cavopulmonary connection (n = 16), concomitant with total cavopulmonary connection (n = 8), or after total cavopulmonary connection (n = 28, median 1.8 years post-operatively). Freedom from pacemaker implantation following total cavopulmonary connection at 10 years was 92%. Twelve patients needed revision of electrodes due to lead dysfunction (n = 9), infections (n = 2), or dislocation (n = 1). Lead energy thresholds were stable, and freedom from pacemaker lead revision at 10 years after total cavopulmonary connection was 78%. Congenitally corrected transposition of the great arteries (odds ratio: 6.6, confidence interval: 2.0-21.5, p = 0.002) was identified as a factor associated with pacemaker implantation before total cavopulmonary connection. Pacemaker rhythms for Fontan circulation were not a risk factor for survival (p = 0.226), protein-losing enteropathy/plastic bronchitis (p = 0.973), or thromboembolic complications (p = 0.424). CONCLUSIONS In our cohort of patients following total cavopulmonary connection, freedom from pacemaker implantation at 10 years was 92% and stable atrial and ventricular lead energy thresholds were observed. Congenitally corrected transposition of the great arteries was at increased risk for pacemaker implantation before total cavopulmonary connection. Having a pacemaker in the Fontan circulation had no adverse effect on survival, protein-losing enteropathy/plastic bronchitis, or thromboembolic complications.

Oxygen inhalation decreases the central venous pressure in adult patients late after Fontan operations. J Cardiol 2024:S0914-5087(24)00036-4. [PMID: 38401702 DOI: 10.1016/j.jjcc.2024.02.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 02/15/2024] [Accepted: 02/16/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND Elevated central venous pressure (CVP) and decreased arterial oxygen saturation (SaO2) are the characteristics of patients after Fontan operations and determine morbidity and mortality in the long-term. Oxygen inhalation therapy theoretically increases SaO2 and may decrease the elevated CVP in these patients. However, there is no previous study to support this hypothesis. This study aimed to determine the acute effects of oxygen inhalation on the hemodynamics of adult patients late after Fontan operations using cardiac catheterization. METHODS This study enrolled 58 consecutive adult patients (median age, 30 years; female, n = 24) who had undergone Fontan operations. We assessed the hemodynamic changes during oxygen inhalation (2 L/min) with a nasal cannula in cardiac catheterization. We divided the studied patients into two groups according to the reduction in CVP during oxygen inhalation using the median value: responders (>2 mmHg) and non-responders (≤2 mmHg). Clinical characteristics of the responders to oxygen inhalation were investigated with uni- and multivariate analyses. RESULTS SaO2 increased from 93.3 % (91.3-94.5 %) to 97.5 % (95.2-98.4 %) (p < 0.001) and CVP decreased from 12 mmHg (11-14 mmHg) to 10 mmHg (9-12 mmHg) (p < 0.001) after oxygen inhalation. There was a weak but significant correlation between the increase in SaO2 and the decrease in CVP (R = 0.29, p = 0.025). Pulmonary blood flow increased from 4.1 L/min (3.5-5.0 L/min) to 4.4 L/min (3.7-5.3 L/min) (p = 0.007), while systemic blood flow showed no significant changes. A multivariate analysis revealed that high baseline CVP was associated with a larger decrease in CVP (>2 mmHg) after oxygen inhalation. CONCLUSIONS Oxygen inhalation increased SaO2 and decreased CVP, especially in patients with high baseline CVP. Further studies with home oxygen therapy are needed to investigate the long-term effects of oxygen inhalation in adult patients who underwent Fontan operations.

Abstract
OBJECTIVE To identify early postoperative haemodynamic and laboratory parameters predicting outcomes following total cavopulmonary connection. METHODS Patients who underwent total cavopulmonary connection between 2012 and 2021 were evaluated. Serial values of mean pulmonary artery pressure, mean arterial pressure, peripheral oxygen saturation, and lactate levels were collected. The influence of these variables on morbidities was analyzed. Cut-off values were calculated using the receiver operating characteristic analysis. RESULTS A total of 249 patients were included. All patients had previous bidirectional cavopulmonary shunt. Median age and weight at total cavopulmonary connection were 2.2 (1.8-2.7) years and 11.7 (10.7-13.4) kg, respectively. All patients were extubated in the ICU at a median of 3 (2-5) hours after ICU admission. Postoperative pulmonary artery pressure, around 12 hours after extubation, was significantly associated with chest tube drainage (p = 0.048), chylothorax (p = 0.021), ascites (p = 0.016), and adverse events (p = 0.028). Receiver operating characteristic analysis revealed a cut-off value of 13-15 mmHg for chest tube drainage and chylothorax and 17 mmHg for ascites and adverse events. Mean arterial pressure 1 hour after extubation was associated with prolonged chest tube drainage (p = 0.015) and adverse events (p = 0.008). Peripheral oxygen saturation 6 hours after extubation (p = 0.003) was associated with chest tube duration and peripheral oxygen saturation 1 hour after extubation (p < 0.001) was associated with ascites. Lactate levels on 2nd postoperative day (p = 0.022) were associated with ascites and lactate levels on 1st postoperative day (p = 0.009) were associated with adverse events. CONCLUSIONS Higher pulmonary artery pressure, lower mean arterial pressure, lower peripheral oxygen saturation, and higher lactate in early postoperative period, around 12 hours after extubation, predicted in-hospital and post-discharge adverse events following total cavopulmonary connection.

Abstract
Several device designs for cavopulmonary mechanical circulatory support (MCS) are under investigation, however, challenged by the Fontan population's heterogeneity in size, cardiovascular and thoracic anatomy. This study aimed to preclinically assess the anatomical compliance of proposed device designs in silico. Representative double- and single-outlet cavopulmonary assist device (CPAD) designs were virtually implanted into CT imaging data of 10 patients previously palliated with total cavopulmonary connection (TCPC) for functionally univentricular hearts. Anatomical device compatibility was characterized concerning pump proximity to cardiovascular, respiratory and thoracic structures, as well as pump in- and outflow graft configuration. In 10 Fontan patients with a median age of 10.4 years (interquartile range [IQR] 5.0-15.3 years) and a median body surface area of 1.09 m2 (IQR 0.76-1.28 m2), implantation of a double-outlet CPAD was feasible in 1 patient (10%). In all other, adverse device intersection with the trachea and (neo-)aorta, or posterior pulmonary artery outflow graft kinking were observed. A single-outlet design permitted enhanced device mobilization adapting to individual anatomical conditions, resulting in device fit in nine of 10 patients (90%). Despite vast anatomical variations among single ventricle patients, a single-outlet device design may provide intracorporeal cavopulmonary MCS to a broad spectrum of failing Fontan patients.

Abstract
INTRODUCTION Without participating in a contractile chamber, the Fontan procedure seeks to create a separation of oxygenated and deoxygenated blood in patients with univentricular heart, reducing the risks of long-term hypoxemia and improving their survival. This study describes the clinical outcomes of children undergoing the Fontan procedure between 2000 and 2020 in a tertiary referral hospital care centre in southwestern Colombia. MATERIALS AND METHODS A retrospective observational descriptive study. The 81 patients who underwent the Fontan procedure were included. Categorical variables were presented with percentages and continuous variables with measures of central tendency according to the distribution of the data evaluated through the Shapiro-Wilk test. Sociodemographic, clinical, surgical variables, complications, and mortality were described. RESULTS Between 2000 and 2020, 81 patients underwent the Fontan procedure: 43 (53.1%) males and a median age of 5.3 years (interquartile range 4.3-6.6). The most common diagnosis was tricuspid atresia (49.4%). The median mean pulmonary arterial pressure was 12 mmHg (interquartile range 10-15), the Nakata index 272 mm2/m2 (interquartile range 204-327), and the McGoon index (interquartile range 1.86-2.3). Seventy-two (88.9%) patients underwent extracardiac Fontan and 44 (54.3%) patients underwent fenestration. The median hospitalisation days were 19 days. The main complication was coagulopathy (19.8%), mortality in the first month between 2000 and 2010 was 8.6%, and after 2010 was 1.2%. CONCLUSION The Fontan procedure is a palliative surgery for children with complex heart disease. According to anatomical and physiological variables, the proper choice of patients determines the short- and long-term results.

Abstract
BackgroundThis study investigated the volume and duration of pleural and mediastinal effusions following extracardiac total cavopulmonary connection, as well as preoperative risk factors and their impact on outcome.Materials and methodsA total of 210 patients who underwent extracardiac total cavopulmonary connection at our center between 2012 and 2020 were included in this study. Postoperative daily amount of pleural and mediastinal drainage were collected and factors influencing duration and amount of effusions were analyzed. The impact of effusions on adverse events was analyzed.ResultsMedian age at extracardiac total cavopulmonary connection was 2.2 (interquartile range, 1.8–2.7) years with median weight of 11.6 (10.7–13.0) kg. Overall duration of drainage after extracardiac total cavopulmonary connection was 9 (6–17) days. The total volume of mediastinal, right pleural, and left pleural drainage was 18.8 (11.9–36.7), 64.4 (27.4–125.9), and 13.6 (0.0–53.5) mL/kg, respectively. Hypoplastic left heart syndrome (p = 0.004) and end-diastolic pressure (p = 0.044) were associated with high volume of drainages, and hypoplastic left heart syndrome (p = 0.007), presence of aortopulmonary collaterals (p = 0.002), and high end-diastolic pressure (p = 0.023) were associated with long duration of drainages. Dextrocardia was associated with higher volume (p < 0.001) and longer duration (p = 0.006) of left pleural drainage. Duration of drainage was associated with adverse events following extracardiac total cavopulmonary connection (p = 0.015).ConclusionVolume and duration of pleural and mediastinal effusions following extracardiac total cavopulmonary connection were related with hypoplastic left heart syndrome, aortopulmonary collaterals, and end-diastolic pressure. The duration of drainage for effusions was a risk factor for adverse events after total cavopulmonary connection.

Influence of fenestration on long-term Fontan survival. Cardiol Young 2022; 32:1021-1026.

Abstract
INTRODUCTION Fenestration in the total cavopulmonary connection system may improve the outcome of patients with significant risk factors for Fontan haemodynamics. Our study aims to analyse the difference in long-term survival between non-fenestrated and fenestrated patients. METHODS All consecutive patients (n = 351) who underwent total cavopulmonary connection between 1992 and 2016 were identified. Six early deaths were excluded resulting in a group of 345 patients. Median (interquartile range,) length of follow-up was 14.4 (7.1-19.7) years. Freedom from the composite endpoint of death, total cavopulmonary connection take-down or indication for a heart transplant was analysed. RESULTS Fenestration was absent in 237 patients (68.7%, Group 1), was created and closed later in 79 patients (22.9%, Group 2), and remained open in 29 patients (8.4%, Group 3). Mean survival probability until composite endpoint was 97.1 and 92.9% at 10 and 20 years, respectively. Patients with patent fenestration had worse survival (p < 0.001) as compared to both the non-fenestrated and fenestration closure groups. Despite a similar outcome, exercise capacity was lower in Group 2 than 1 (p = 0.013). In 58 patients with interventional fenestration closure, Nakata index was lower at the time of closure than pre-operatively, and both the pressure in the circuit and oxygen saturation in the aorta increased significantly (p < 0.001). CONCLUSIONS Patients with persisting risk factors preventing fenestration closure are at higher risk of reaching the composite endpoint. Patients after fenestration closure have the worse functional outcome; their survival is, however, not different from the non-fenestrated group.

Post-operative Morbidity and Mortality After Fontan Procedure in Patients with Heterotaxy and Other Situs Anomalies. Pediatr Cardiol 2022; 43:952-959. [PMID: 35064275 DOI: 10.1007/s00246-021-02804-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Accepted: 12/09/2021] [Indexed: 10/19/2022]
Abstract
Heterotaxy is a complex, multisystem disorder associated with single ventricle heart disease and decreased survival. Ciliary dysfunction is common in heterotaxy and other situs abnormalities (H/SA) and may increase post-operative complications. We hypothesized that patients with H/SA have increased respiratory and renal morbidities and increased in-hospital mortality after Fontan procedure. We queried the Pediatric Health Information System database for hospitalizations with ICD-9/10 codes for Fontan procedure in patients aged 1 through 11 years from 2004 to 2019. H/SA was identified by codes for dextrocardia, situs inversus, asplenia/polysplenia, or atrial isomerism and compared to non-H/SA controls. Outcomes were in-hospital mortality or heart transplantation, ECMO, hemodialysis, length of stay (LOS), and mechanical ventilation or vasoactive medication use ≥ 4 days. We adjusted estimates with multivariable logistic regression. Of 7897 patients at 50 centers, 1366 (17%) met criteria for H/SA. H/SA had worse outcomes for all study measures: death/transplantation (1.9 vs 1.1%, OR 1.74 (95% CI 1.01-3.03); p = 0.047), ECMO (3.7 vs 2.3%, OR 1.74 (1.28-2.35); p < 0.001), hemodialysis (2.1 vs 1.2%, OR 1.66 (1.06-2.59); p = 0.026), prolonged mechanical ventilation (13.2% vs 7.6%, OR 1.85 (1.53-2.25); p < 0.001) and vasoactive medication use (29.4 vs 19.7%, OR 1.65 (1.43-1.90), and longer LOS (11 (8-17) vs 9 (7-14) days; p < 0.001). H/SA is associated with increased cardiovascular, renal, and respiratory morbidity, as well as in-hospital mortality after Fontan procedure. Attention to renal and respiratory needs may improve outcomes in this difficult population. The relationship between ciliary dysfunction and lung and renal morbidity should be explored further.

Abstract
OBJECTIVES We sought to evaluate the long-term survival and risk factors for morbidity and mortality in our cohort of patients after Extracardiac (EC) Fontan. METHODS We collected and analyzed follow-up data until September 2020 for all patients who underwent EC Fontan operation at our institution from November 1988 to November 2015. RESULTS Out of 406 patients treated with EC Fontan at a mean age of 5.4 ± 4.5 years, 372 (91.6%) were discharged home; 15% were lost to follow-up. The Median follow-up was 14.6 years (IQR 8.7-20.3). Two hundred patients (54%) had a good long-term outcome, with an event-free long-term survival, but late adverse events of any kind needing interventional or surgical reoperations were reported in 128 patients (34%). Forty-four patients (12%) developed late Fontan failure. Thirty-seven survivors (10%) had late arrhythmias, with the need for pacemaker implantation. Obstruction of the cavopulmonary pathway occurred in forty-nine patients (13%), but just 8 pts needed conduit surgical replacement. At 32 years, the survival probability was 84%. The risk of orthotopic heart transplant (HT), considering death as a competing event, (showed as cumulative incidence) was 12.5%. A preoperative diagnosis of hypoplastic left heart syndrome (HLHS) was an independent risk factor for the need for HT. CONCLUSIONS The EC Fontan shows satisfactory long-term survival and low incidence of adverse events and late failure. Conduit replacement is rare, and its longevity may not represent a substantial issue in these patients. However, as with other technical variants, the need for reoperations during long-term follow-up is a significant challenge.

Hemodynamic Characteristics After Fontan Procedure in Patients with Down's Syndrome. Pediatr Cardiol 2022; 43:360-365. [PMID: 34498105 DOI: 10.1007/s00246-021-02727-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Accepted: 09/01/2021] [Indexed: 11/25/2022]
Abstract
Patients with Down's syndrome (DS) are generally regarded as not being good candidates for the Fontan procedure. However, detailed hemodynamic changes over time are not fully clarified. A retrospective chart review of all patients with DS who underwent the Fontan procedure and 5 times that number of Fontan patients without DS performed in Fukuoka Children's Hospital and Kyushu University Hospital. Seven Fontan patients with DS were identified, and 35 Fontan patients without DS were recruited. During the mean observational periods of 14.7 years and 15.0 years (DS and non-DS, respectively) after the Fontan procedure, only one DS patient died. Central venous pressure (CVP) and transpulmonary pressure gradient significantly increased, and arterial oxygen saturation significantly decreased over time in DS patients after the Fontan procedure compared with those without DS. CVP in DS patients after the Fontan procedure increased over time compared with non-DS patients. Better management including the efficacy of Pulmonary arterial hypertension-specific therapy should be clarified in further studies.

Abstract
OBJECTIVE This study aimed to evaluate and discuss the outcomes of creating a single systemic-pulmonary shunt and reconstruction of the pulmonary artery continuity in patients with a single functional ventricle, absent central pulmonary artery, and bilateral patent ductus arteriosus. METHODS Six infants diagnosed with a functional single ventricle, absent central pulmonary artery, and bilateral patent ductus arteriosus were treated by creating a single systemic-pulmonary shunt and reconstructing the pulmonary artery continuity (primary operation) between January 2010 and September 2020. Pulmonary artery continuity was ensured using the remnant pulmonary artery and an autologous pericardial patch in five patients and a rolled autologous pericardium in one patient. RESULTS All patients eventually underwent total cavopulmonary connection. Two patients underwent intrapulmonary artery septation before Glenn or total cavopulmonary connection procedure. The median follow-up period was 9.02 years (interquartile range, 3.90-9.53). No late deaths were observed. CONCLUSIONS Our strategy of establishing a single systemic-pulmonary shunt with reconstruction of the pulmonary artery continuity was useful for treating patients with a functional single ventricle with absent central pulmonary artery and bilateral patent ductus arteriosus. This procedure helped accomplish pulmonary artery growth and ensured an appropriate volume load after total cavopulmonary connection.

Abstract
OBJECTIVE To analyze the aerobic fitness and evolution of exercise tolerance in patients with single-ventricle physiology after total cavopulmonary connection (TCPC) with an extracardiac conduit (ECC). STUDY DESIGN This retrospective cohort study included patients with previous ECC-TCPC who underwent cardiopulmonary exercise testing (CPET) between September 2010 and September 2019. Patients who completed at least 2 tests (≥6 months apart) with adequate levels of effort were recruited for the serial CPET evaluation. RESULTS We identified 70 patients (50% male) with a mean age of 6.45 ± 5.14 years at ECC-TCPC and 15.67 ± 5.03 years at the initial CPET. The peak oxygen consumption (peak VO2) to predicted value (peak PD) was 55.90 ± 16.81%. Twenty of the 70 identified patients (50% male) were recruited for serial analysis. The average number of CPETs was 2.6 per patient. The average duration from the first CPET to the last CPET was 3.64 years. The peak VO2 and PD increased slowly, with mean rates of 38.77 ± 129.01 mL/min and 1.66 ± 6.40%, respectively, during the study period. CONCLUSIONS Although the patients had lower exercise tolerance after ECC-TCPC compared with their normal peers, exercise tolerance appears to have been preserved over the adolescent period in those who underwent serial testing after ECC-TCPC.

Abstract
Few reports have described the implantation and management of an implantable ventricular assist device in patients with functional uni-ventricular anatomy. We herein report a case who underwent HVAD implantation due to severe cardiac dysfunction and Fontan failure in the remote period following total cavo-pulmonary connection. Double valve replacement was subsequently required one year later due to repeated Fontan failure caused by the progression of aortic and atrioventricular regurgitation. The low-profile and saddle-shaped sewing cuff design of the MITRIS were beneficial for avoiding the HVAD inflow and atrioventricular valve interference in the less-dilated ventricle.

Eur J Cardiothorac Surg 2021; 61:497-504. [PMID: 34355744 DOI: 10.1093/ejcts/ezab355] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 06/14/2021] [Accepted: 06/17/2021] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES The age at which the Fontan operation is performed varies globally. Over the last decade, the median age of patients having the Fontan in Australia and New Zealand has been 4.6 years, including 6% of patients younger than 3 years. Long-term outcomes of an early Fontan operation are unclear and are described in this study. METHODS Patients from the Australian and New Zealand Fontan Registry were grouped by age at Fontan. A Fontan before 3 years (early Fontan) was compared to the combined second and third quartiles by age at surgery in the Registry (3.6-6.1 years; control). Outcomes included Fontan failure (death, transplant, New York Heart Association functional group III/IV heart failure, Fontan takedown or conversion, protein losing enteropathy and plastic bronchitis), arrhythmias, thromboembolism and reinterventions. RESULTS A total of 191 patients who had early Fontan operations were compared to 781 controls. Profound or progressive cyanosis was noted more frequently in the early than in the control group (63% vs 23%; P < 0.001). The early group was followed up for a median 22.1 years. The incidence of long-term failure was similar between the 2 groups (early, 1.08 failures per 100 patient-years of follow-up vs control, 0.99; log-rank P = 0.79). Adjusted for risk factors, early age at Fontan was not a risk factor for long-term failure [hazard ratio (HR) 1.16, 95% confidence interval (CI) 0.77-1.76; P = 0.48], new-onset arrhythmia (HR 0.93, 95% CI 0.63-1.39; P = 0.73), thromboembolism (HR 0.50, 95% CI 0.28-0.91; P = 0.024) or reintervention (HR 1.08, 95% CI 0.80-1.45; P = 0.62). CONCLUSIONS Having the Fontan operation at an early age was not a risk factor for short- or long-term adverse outcomes in our cohort.

Abstract
AIM To describe the clinical and hemodynamic characteristics of Fontan failure in children listed for heart transplant. METHODS In a nested study of the Pediatric Heart Transplant Society, 16 centers contributed information on Fontan patients listed for heart transplant between 2005and 2013. Patients were classified into four mutually exclusive phenotypes: Fontan with abnormal lymphatics (FAL), Fontan with reduced systolic function (FRF), Fontan with preserved systolic function (FPF), and Fontan with "normal" hearts (FNH). Primary outcome was waitlist and post-transplant mortality. RESULTS 177 children listed for transplant were followed over a median 13 (IQR 4-31) months, 84 (47%) were FAL, 57 (32%) FRF, 22 (12%) FNH, and 14 (8%) FPF. Hemodynamic characteristics differed between the 4 groups: Fontan pressure (FP) was most elevated with FPF (median 22, IQR 18-23, mmHg) and lowest with FAL (16, 14-20, mmHg); cardiac index (CI) was lowest with FRF (2.8, 2.3-3.4, L/min/m2). In the entire cohort, 66% had FP >15 mmHg, 21% had FP >20 mmHg, and 10% had CI <2.2 L/min/m2. FRF had the highest risk of waitlist mortality (21%) and FNH had the highest risk of post-transplant mortality (36%). CONCLUSIONS Elevated Fontan pressure is more common than low cardiac output in pediatric failing Fontan patients listed for transplant. Subtle hemodynamic differences exist between the various phenotypes of pediatric Fontan failure. Waitlist and post-transplant mortality risks differ by phenotype.

Abstract
An intractable pleural effusion is a common comorbidity of a Fontan operation, occasionally leading to undesirable outcomes. The preventive effect of aortopulmonary collateral (APC) coil embolization against a pleural effusion before a Fontan operation is still controversial.This is a retrospective single-center study; among 227 Fontan cases, 57 cases with complete MRI data were analyzed at first. Factors associated with the duration of pleural drainage (median: 6 (2-41) days) and that of postoperative hospital stay (median: 25 (14-91) days) were analyzed using a multiple regression analysis. The pulmonary artery index (PAI; Nakata index) was associated with both the pleural drainage duration (P < 0.05, r2 = 0.17) and postoperative hospital stay (P < 0.05, r2 = 0.10).Thereafter, all the 227 patients were classified into the following three groups: Group A (12 patients in whom the embolization was performed within 30 days before the Fontan surgery), Group B (131 patients in whom the embolization was performed more than 30 days before the Fontan surgery), and Group C (84 patients in whom the embolization was not performed). Patients in Group A were found to be associated with the shortest length of both periods (P < 0.05).Lower PAI values were related to a prolonged pleural drainage duration and postoperative hospital stay. APC coil embolizations may reduce the risk if they are performed shortly (less than 30 days) before the operation.

Recurrent sustained atrial arrhythmias and thromboembolism in Fontan patients with total cavopulmonary connection. IJC HEART & VASCULATURE 2021; 33:100754. [PMID: 33786365 PMCID: PMC7988316 DOI: 10.1016/j.ijcha.2021.100754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Revised: 02/25/2021] [Accepted: 02/27/2021] [Indexed: 11/29/2022]
Abstract
Background Total cavopulmonary connection (TCPC) is associated with a lower risk of incident atrial arrhythmias as compared to atriopulmonary Fontan, but the risk of recurrent atrial arrhythmias is unknown in this population. The purpose of this study was to determine the incidence and risk factors for recurrent atrial arrhythmias and thromboembolic complications in patients with TCPC. Methods This is a retrospective multicenter study conducted by the Alliance for Adult Research in Congenital Cardiology (AARCC), 2000-2018. The inclusion criteria were TCPC patients (age > 15 years) with prior history of atrial arrhythmia. Results A total of 103 patients (age 26 ± 7 years; male 58 [56%]) met inclusion criteria. The mean age at initial arrhythmia diagnosis was 13 ± 5 years, and atrial arrhythmias were classified as atrial flutter/tachycardia in 85 (83%) and atrial fibrillation in 18 (17%). The median duration of follow-up from the first episode of atrial arrhythmia was 14.9 (12.1-17.3) years, and during this period 64 (62%) patients had recurrent atrial arrhythmias (atrial flutter/tachycardia 51 [80%] and atrial fibrillation 13 [20%]) with annual incidence of 4.4%. Older age was a risk factor for arrhythmia recurrence while the use of a class III anti-arrhythmic drug was associated with a lower risk of recurrent arrhythmias. The incidence of thromboembolic complication was 0.6% per year, and the cumulative incidence was 4% and 7% at 5 and 10 years respectively from the time of first atrial arrhythmia diagnosis. There were no identifiable risk factors for thromboembolic complications in this cohort. Conclusions Although TCPC provides superior flow dynamics and lower risk of incident atrial arrhythmias, there is a significant risk of recurrent arrhythmias among TCPC patients with a prior history of atrial arrhythmias. These patients may require more intensive arrhythmia surveillance as compared to other TCPC patients.

Abstract
Thrombus formation is a feared complication following bidirectional cavopulmonary shunt (BCPS). We aimed to investigate the effect of thrombus formation on outcome. BCPS was performed in 525 patients at our center between 1998 and 2018. The impacts of thrombus formation on survival and probability of Fontan completion were analyzed, and risk factors for thrombus formation were examined. Thrombus formation occurred in 30 patients (5.7%). Compared with the remaining 495 patients, there was no significant difference in the median age at BCPS (4.9 vs 4.7 months; P = 0.587). However, unbalanced atrioventricular septal defects (17 vs 5%; P = 0.008) and preoperative ventricular dysfunction (23.3 vs 8%; P = 0.004) were more frequent in patients who developed a thrombus. Thrombolytic therapy was performed in all patients and surgical thrombus removal was required in 13 patients. In-hospital mortality was higher in patients with thrombus (30.0 vs 2.2%; P < 0.001). Of 505 hospital survivors, an estimated survival at 1 year after hospital discharge following BCPS was 84.4% (95% CI, 76.1-92.7%) in patients with thrombus and 96.8% (95% CI, 96.0-97.6%) in those without (P < 0.001). Cumulative incidence of Fontan completion at 3 years after BCPS was 52.8% (95% CI, 30.3-75.2%) in patients with thrombus and 90.1% (95% CI, 87.2-92.9%) in those without (P = 0.004). Higher left atrial pressure (OR = 1.165; P = 0.029) and longer cardiopulmonary bypass time (OR = 1.013, P = 0.001) at BCPS were independent risk factors for thrombus formation after BCPS. Thrombus formation after BCPS poses a significant risk for survival and Fontan completion. Preoperative higher left atrial pressure and longer cardiopulmonary bypass time are significant risk factors.

Abstract
Background Liver cancer (LC) is a serious late complication after the Fontan operation. However, the incidence, predictors, and prognosis remain unknown. The purpose of our study was to determine these clinical characteristics. Methods and Results We assessed liver function in 339 consecutive patients who had undergone the Fontan procedure from 2005 to 2019. LC was histologically diagnosed in 10 patients after a median period of 2.9 years (range: 0.3–13.8; median age: 29.9 years [range: 14.4–41.5 years]; overall median post–Fontan procedure follow‐up: 25.6 years [range: 13–32.1 years]), and the annual incidence was 0.89%. Over the entire post‐Fontan follow‐up period, the annual incidences of new‐onset LC in the second, third, and fourth decades were 0.14%, 0.43%, and 8.83%, respectively. The patients with LC had longer follow‐up periods, higher levels of AFP (α‐fetoprotein), and higher values of liver fibrosis indices (P<0.01–0.0001). Moreover, all indices were predictive of new‐onset LC (P<0.01–0.0001). The LC treatments were surgical resection (n=3), transarterial chemoembolization (n=3), radiofrequency ablation (n=2), and hospice care (n=2). During a median follow‐up of 9.4 months, 4 patients died; the survival rate at 1 year was 60%, and it was better among asymptomatic patients (P<0.01). Conclusions The LC incidence rapidly increased ≥30 years after the Fontan procedure, and liver fibrosis indices and AFP were predictive of new‐onset LC. These LC‐predictive markers should be monitored closely and mandatorily for early LC detection and better prognosis.

Abstract
BACKGROUND/PURPOSE Fontan operation is the standard surgical procedure for achieving long-term survival in single-ventricular complex congenital heart diseases (SV-CHD). We aim to identify the perioperative outcomes and impact of heterotaxy syndrome (HS) after Fontan operation in a tertiary pediatric cardiology center. METHODS Medical records were reviewed for all patients who received Fontan operation and who were born between 1997 and 2017 in our institution. Preoperative, operative, and postoperative risk factors for perioperative mortality and morbidity were analyzed. RESULTS Totally, 154 patients were enrolled (103 SV-CHD and 51 HS), and the male to female ratio was 92:62. The mean age of Fontan operation was 5.1 years, and extracardiac conduit comprised the majority (90.9%) of Fontan operation. Overall perioperative event-free survival to discharge was 91.6% (84.3% in HS and 95.1% in other SV-CHD, P = 0.032). For secondary outcomes, length of intensive care stay and duration of pleural effusion drainage were not significantly different between patients with HS and other SV-CHD, but postoperative arrhythmia was more common in HS group (31.4% vs. 12.6%, P = 0.005). In multivariable regression analysis, preoperative risk factors including operation year before 2007 and high PAP and postoperative factors of elevated postoperative CVP were associated with worse outcomes. HS was not a predictor of worse outcome after adjusting for preoperative PAP and operation era. CONCLUSION Surgical outcome has improved much in current era. Perioperative outcome is poorer in patients with HS than other SV-CHD, but HS is not a predictor of perioperative mortality after adjusting for hemodynamic factors.

Abstract
BACKGROUND Fontan outcomes data from large volume Middle Eastern Centres are lacking. We report our experience after the Fontan operation from a tertiary cardiac centre in Saudi Arabia. METHOD All 458 consecutive patients who had Fontan surgery 1986 through 2015 at the Prince Sultan Cardiac Centre, Riyadh [PSCC], Saudi Arabia, were evaluated for baseline, early and late post-operative outcomes and their uni and multivariate determinants. RESULTS The mean age at Fontan operation was 7 years [IQR 4.8-9.0]. The most common anatomic diagnoses were tricuspid atresia (104 [23%]) and double-inlet left ventricle (81 [18%]). Only 3 patients in the present series had hypoplastic left heart syndrome [HLHS]. Early mortality [i.e. during Fontan surgical admission] was 3.1%. At late follow-, 35 (8%) patients were lost to follow up. The 1, 5, 10, 20 and 30 year survival was 96%, 94%, 93% and 85%, respectively. In the modern surgical era, 5, 10 and 15 year survival were 96%, 95% and 93% respectively. Univariate determinants of death or transplant were hypoalbuminemia, elevated NtProBNP >500, surgical era prior to 1999, the lack of Fontan fenestration, and prior atriopulmonary Fontan [APF] procedure. On multivariate analysis, surgical era before 1999 and prior APF procedure were independently associated with death or transplant. CONCLUSIONS Fontan patients from this large volume Middle Eastern centre have comparable early and late mortality outcomes compared to prior published reports. Rigorous selection criteria at the time of Fontan, and Fontan specific dedicated care teams are likely contributors to this success.

Abstract
Objective We evaluated additional pulmonary blood flow at the time of bidirectional cavopulmonary shunt and its effects on the Fontan procedure and long-term outcome of Fontan circulation and liver function. Methods We included 22 patients (16 boys, 6 girls) having undergone bidirectional cavopulmonary shunt with additional pulmonary blood flow between April 2002 and January 2016. Mean age and body weight were 20 ± 13 months and 7.5 ± 6.5 kg, respectively. We retrospectively evaluated the patients’ clinical data, including cardiac catheterization data, liver function, and liver fibrosis markers. Results All patients were alive with a New York Heart Association status of I at the long-term follow-up. Changes between pre-bidirectional cavopulmonary shunt and 101 months after the Fontan procedure included the following: the cardiothoracic ratio of chest X-ray decreased from 52.2 ± 3.9% to 41.8 ± 5.9% (p < 0.001); systemic ventricle end-diastolic pressure decreased from 11.4 ± 3.2 mmHg to 6.9 ± 3.6 mmHg (p < 0.001); and the pulmonary artery index decreased from 485.1 ± 272.3 to 269.5 ± 100.5 (p = 0.02). Type IV collagen, hyaluronic acid, and procollagen levels increased over the normal range 116 months after the Fontan procedure. Conclusions The additional pulmonary blood flow at the time of bidirectional cavopulmonary shunt may contribute to pulmonary arterial growth at the Fontan procedure with low pulmonary arterial resistance and without ventricle volume overload. The Fontan circulation was well-maintained at the long-term follow-up, while liver fibrosis markers were above their normal values.

Abstract
BACKGROUND The long-term outcomes of a total cavopulmonary connection (TCPC) with an extracardiac conduit (ECC) for patients with apicocaval juxtaposition (ACJ) remain unclear. METHODS A total of 38 patients with ACJ who underwent TCPC with ECC between 1998 and 2014 were enrolled in this study. For 19 patients with a superior vena cava - inferior vena cava contralateral position, a long-curved route rounding the opposite side of the apex was selected (CC group). For 11 patients with a superior vena cava-inferior vena cava ipsilateral position, a long-curved route was principally selected (IC group); however, a short, straight route was selected for 8 patients because there was sufficient space behind the ventricular apex (IS group). RESULTS Follow-up was completed in all patients, with a mean follow-up duration of 13.2 ± 4.9 years. The angles of the caudal conduit anastomosis site measured from the frontal view of cineangiography had significantly straightened in the CC group from 1 year to 15 years (P < .05) and in the IC group from 1 year to 10 years (P < .05). There were 2 late mortalities and 6 reoperations during follow-up. Overall survival and freedom from reoperation rates at 15 years were 95% and 82%, respectively. There were no conduit-related or route-related complications such as death, reoperations, pulmonary venous obstructions, conduit obstructions, or pulmonary arteriovenous malformations in any of the groups. CONCLUSIONS Even though chronologic geometric changes of curved ECCs were observed, TCPC with ECC for patients with ACJ can be safely applied without conduit- or route-related complications in long-term follow-up.

Abstract
BACKGROUND As a result of the surgical techniques now being employed, the survival rate in patients after undergoing the Fontan operation has improved. The aims of this study were focused on determining the survival rate and predictors of early mortality. METHODS In a retrospective cohort study, 117 consecutive patients who underwent the Fontan operation were recruited. Multivariate Cox proportional regression analysis was used to assess the predictors of early mortality, defined as death within 30 days after the Fontan operation. RESULTS The median follow-up time was 6.1 years. The median age at the time of the Fontan operation was 5.7 years. Survival rates in the patients at 5, 10, and 15 years postoperatively were 92%, 87% and 84%, respectively. Using univariate Cox regression analysis, the predictors of early mortality were found to be postoperative mean pulmonary artery pressure ≥23 mm Hg (hazard ratio 26.0), renal failure (hazard ratio 9.5), heterotaxy syndrome (hazard ratio 5.3), and uncorrected moderate or severe atrioventricular valve regurgitation (hazard ratio 9.4). After adjusting for confounding factors using multivariate Cox regression analysis, the predictors of early mortality were found to be postoperative mean pulmonary artery pressure ≥23 mm Hg (hazard ratio 23.2) and uncorrected moderate or severe atrioventricular valve regurgitation (hazard ratio 8.2). CONCLUSIONS Uncorrected moderate or severe atrioventricular valve regurgitation and postoperative mean pulmonary artery pressure ≥23 mm Hg are independent predictors of early mortality after the Fontan operation. Patients with these factors should undergo aggressive management to minimize morbidity and mortality.

Abstract
BACKGROUND Currently, the extracardiac conduit total cavopulmonary connection (eTCPC) is the most widely used for Fontan modification worldwide. Nevertheless, there have been some cases that are difficult for performing eTCPC because of their anatomical complexity, such as apicocaval juxtaposition. For such cases, in 2002, we introduced the intra-extracardiac TCPC (ieTCPC). METHODS We reviewed our 20-year single-center experience with 316 TCPC patients to compare eTCPC (n = 277) and ieTCPC (n = 39) in terms of mortality and morbidity. ieTCPC was indicated for the cases in which there was concern that the TCPC conduit would be too curved for ordinary eTCPC. RESULTS Early death occurred in 1 patient and late death occurred in 15 patients. The actuarial survival rate in the eTCPC and the ieTCPC groups at 10 years were 95.1% and 100.0%, respectively. There was no significant difference in actuarial survival between eTCPC and ieTCPC patients. In the multivariate analysis, preoperative superior vena cava pressure and preoperative oxygen saturation were found to be the independent predictor for postoperative mortality. There was also no significant difference in actuarial rate of freedom from late-occurring complications between eTCPC and ieTCPC groups. In the multivariate analysis, dominant right ventricle and preoperative SVC pressure were independent predictors for late-occurring complications. CONCLUSIONS The clinical outcomes in patients who undergo eTCPC and ieTCPC appear to be excellent, with low mortality and morbidity rates in the midterm. ieTCPC may be a good option for TCPC cases with anatomical complexity such as apicocaval juxtaposition and separated hepatic vein drainage.

Abstract
OBJECTIVES This study aims to evaluate our 45-year experience with the Fontan procedure and to identify risk factors for late mortality and morbidity. METHODS Demographic, preoperative, perioperative and postoperative characteristics were retrospectively collected for all patients who underwent a Fontan procedure in a single centre between 1972 and 2016. RESULTS The study included 277 Fontan procedures (44 atriopulmonary connections, 28 Fontan-Björk, 42 lateral tunnels and 163 extracardiac conduits). Early failure occurred in 17 patients (6.1%). Median follow-up of the study cohort was 11.9 years (Q1-Q3 7.6-17.5). Longest survival estimates were 31% [95% confidence intervals (CI) 18-44%] at 35 years for atriopulmonary connection/Björk, 87% (95% CI 63-96%) at 20 years for lateral tunnel and 99% (95% CI 96-100%) at 15 years for extracardiac conduit. Estimated freedom from Fontan failure (death, heart transplant, take-down, protein-losing enteropathy, New York Heart Association III-IV) at 15 years was 65% (95% CI 52-76%) for atriopulmonary connection/Björk, 90% (95% CI 73-97%) for lateral tunnel and 90% (95% CI 82-94%) for extracardiac conduit. The development of tachyarrhythmia was an important predictor of Fontan failure [hazard ratio (HR) 2.6, 95% CI 1.2-5.8; P = 0.017], thromboembolic/neurological events (HR 3.6, 95% CI 1.4-9.4; P = 0.008) and pacemaker for sinus node dysfunction (HR 3.7, 95% CI 1.4-9.6; P = 0.008). Prolonged pleural effusion (>21 days) increased the risk of experiencing protein-losing enteropathy (HR 4.7, 95% CI 2.0-11.1; P < 0.001). CONCLUSIONS With modern techniques, survival and freedom from Fontan failure are good. However, Fontan patients remain subject to general attrition. Tachyarrhythmia is an important sign for an adverse outcome. Prevention and early treatment of tachyarrhythmia may, therefore, be paramount in improving the long-term outcome.

Abstract
Postoperative arrhythmias are a frequent and fatal complication after the Fontan operation. However, clinical evidence demonstrating early postoperative arrhythmias in children undergoing the Fontan operation is limited. This study aimed to evaluate the prevalence of arrhythmias and identify the predictors of early postoperative supraventricular tachyarrhythmias (SVTs) after the Fontan procedure.Data were analyzed from 80 pediatric patients who underwent Fontan procedures between April 2000 and December 2017 in a single-center retrospective study. Early postoperative SVTs were defined as arrhythmias within 30 days after the Fontan procedure. We divided the patients into two groups, with or without early postoperative arrhythmias, and the predictors of early postoperative arrhythmias were analyzed. A multivariate logistic regression analysis was performed to determine independent predictors of early postoperative SVTs after the Fontan procedure.Early postoperative SVTs were observed in 21 patients (26.3%). The most common arrhythmia was junctional ectopic tachycardia. After an adjustment, an atrioventricular valve regurgitation (AVVR) grade of ≥2 (odds ratio 10.54, 95% confidence interval 2.52 to 44.17, P = 0.001) and preoperative arrhythmias (odds ratio 26.49, 95% confidence interval 1.64 to 428.62, P = 0.021) were significant predictors of early postoperative SVTs after the Fontan operation.An AVVR grade ≥2 and preoperative arrhythmia were significant predictors associated with early postoperative SVTs. Intervention for AVVR may provide clinical benefit for preventing early postoperative arrhythmias after the Fontan operation.

Abstract
Background: Investigations of ventricular dominance and outcomes after the Fontan procedure have shown conflicting results. This may be due to the inclusion of multiple modifications of the Fontan or the omission of recently identified complications of the procedure. We examined the association between right ventricular dominance (RVD) and morbidity/mortality in a contemporary cohort following the extracardiac (EC) Fontan. Methods: We studied all pediatric patients at our center who underwent a predominantly fenestrated EC Fontan from 2004 to 2016. Outcomes assessed were freedom from (1) Fontan failure (death, takedown, listing for transplantation) and (2) complication (arrhythmia requiring medication, postoperative pacemaker, or implantable cardioverter defibrillator requirement, stroke, thrombosis in the Fontan circuit, protein losing enteropathy, plastic bronchitis, New York Heart Association class >2). We defined the perioperative period as occurring before hospital discharge or within 30 days of the Fontan. Results: A total of 137 patients (median age: 34 months, 62% male, 60% RVD) underwent the EC Fontan. Median duration of follow-up was 5.8 years (interquartile range: 2.4-9.0). Freedom from any event was 82.5% (RVD = 77%, LVD = 91%, χ2(1) = 5.03, P = .025) and RVD was associated with reduced event-free survival (hazard ratio: 2.94, P = .02). No confounders were identified. In the perioperative period, RVD was associated with reduced complication-free survival ( P = .004). After this period, RVD was associated with reduced failure-free survival ( P = .003). Conclusions: In this contemporary, single-center cohort of EC Fontan patients, RVD was associated with inferior outcomes.

Abstract
Abstract
OBJECTIVES
The aim of this study was to investigate the impact of an early extubation strategy on the outcome following extracardiac total cavopulmonary connection.
METHODS
From 1999 through 2017, 458 patients underwent extracardiac total cavopulmonary connection; 257 (56%) patients were managed with an early extubation strategy adopted in 2009 (group A). Their outcome was compared with those of 201 (44%) patients treated before 2009 (group B). In group A, the outcome of unstable patients, defined as >75th percentile for volume administered and inotrope scores, was compared with those of stable patients.
RESULTS
Ventilation time (median: 4 h vs 16 h, P < 0.001), fluid volume administered during the first 24 h (mean: 110 ml/kg vs 164 ml/kg, P = 0.003), chest tube duration (median: 3 days vs 4 days, P = 0.028) and length of intensive care unit stay (median: 6 days vs 7 days, P = 0.001) were less in group A than in group B. The reintubation rate (7% vs 6%, P = 0.547) and early mortality (0.8% vs 1.5%, P = 0.465) were similar between groups. The 80 unstable group A patients received more inotropic support (P < 0.001) and fluid volume (P < 0.001) than stable patients, but the ventilation time (6 h vs 5 h, P = 0.220), the reintubation rate (10% vs 6%, P = 0.283) and the length of intensive care unit stay (7 days vs 6 days, P = 0.590) were similar. In unstable patients, mean arterial pressure before extubation was significantly lower than stable patients (P = 0.001). However, mean arterial pressure in unstable patients increased significantly (P < 0.001) soon after extubation, and became similar to the value in stable patients.
CONCLUSIONS
Early extubation following extracardiac total cavopulmonary connection improves postoperative haemodynamics and recovery regardless of the initial haemodynamic status.

Abstract
UNLABELLED BackgroundsThe aim of this study was to assess the impact of age at bidirectional cavopulmonary anastomosis on haemodynamics after total cavopulmonary connection. METHODS We conducted a retrospective analysis of 100 consecutive patients who underwent total cavopulmonary connection from 2010 to 2014. All patients had previously undergone bidirectional cavopulmonary anastomosis. These patients were classified into two groups according to age at bidirectional cavopulmonary anastomosis: younger group, 6 months (n=67). RESULTS The proportion of hypoplastic left heart syndrome was higher in the younger group (48 versus 4%). After total cavopulmonary connection, the chest tube period was longer in the younger group (10.1±6.6 versus 6.7±4.5 days; p=0.009). Catheterisation 6 months after total cavopulmonary connection revealed that pulmonary artery pressure was higher (11.5±1.9 versus 10.4±2.1 mmHg; p=0.017) and Nakata index was lower (219±79 versus 256±70 mm2/m2; p=0.024) in the younger group. In patients with a non-hypoplastic left heart syndrome, there was no difference in post-operative haemodynamics between two groups, but the total amount of chest drainage after total cavopulmonary connection was larger in the younger group (109±95 versus 55±40 ml/kg; p=0.044). CONCLUSIONS Early bidirectional cavopulmonary anastomosis did not affect the outcome of total cavopulmonary connection. Longer chest tube period, smaller pulmonary artery, and higher pulmonary artery pressure after total cavopulmonary connection were recognised in early bidirectional cavopulmonary anastomosis patients, especially in hypoplastic left heart syndrome.

Abstract
BackgroundNational prevalence and outcomes of Fontan operation in the USA is unknown. Study objective was to determine trends (temporal change) in the annual volume of Fontan operations, in-hospital mortality, postoperative complications and type of hospital discharge.MethodsReview of the Nationwide Inpatient Sample for patients that underwent Fontan operation from 2001 to 2014 using the International Classification of Diseases-Ninth Revision, Clinical Modification procedure code for Fontan operation, that is, 35.94. To evaluate for change in patients’ demographics over the years, we divided the patient population into four groups based on procedure year (2001–2004, 2005–2008, 2009–2011 and 2012–2014).ResultsAn estimated 15 934 Fontan operations were performed in the USA from 2001 to 2014. Median (Q1–Q3) age was 3 (2–4) years and 39.8% were female. Hypoplastic left heart syndrome was the most common (29%) congenital heart disease diagnosis. An estimated 1175 procedures were performed in 2001 and 1340 in 2014, but there was no significant change in the number of procedures per year (p=0.47). There was significant decline in in-hospital mortality from 4.5% (53/1175) in 2001 to 1.1% (15/1340) in 2014 (p=0.009). When we compared event rates between 2001–2004 and 2012–2014 periods, there was significant decline in postoperative cardiac complications (12.6% (459/3640) to 8% (378/4706), p=0.007) and respiratory complications (17.1% (623/3640) to 10.2% (481/4706), p<0.001). However, there was increase in the number of patients discharged to home with healthcare assistance or transferred to another acute care facility (5.8% (211/3640) to 9.4% (443/4706), p=0.01) and inflation-adjusted hospitalisation cost (US$46 978 to US$60 383, p<0.001), but no significant change in length of stay (p=0.73).ConclusionOn the average, 1062 Fontan operations are performed annually in the USA with no change in volume of procedures but a decrease in in-hospital mortality and postoperative complications over a 15-year period.

Abstract
Placement of an epicardial pacemaker system is often preferred over an endocardial system in patients who have undergone a Fontan operation, but data are limited on how these two systems perform over time in patients with Fontan palliation. We performed a retrospective review of adults with Fontan palliation who had pacemaker implantation and interrogation data at Mayo Clinic from 1994 to 2014. Lead parameters, pacing mode, and polarity were collected at the earliest device interrogation report. Clinic notes and device interrogation reports were reviewed at implantation, 6 months, and yearly after implantation to determine impedance, capture threshold (CT), and energy threshold (ET). There were 87 patients with 168 leads in the study cohort. The mean follow-up time was 7.7 years (6 months-19 years). There were 143 epicardial leads (57 atrial and 86 ventricular) and 25 endocardial leads (20 atrial and 5 ventricular). There was no difference in the baseline lead parameters between epicardial and endocardial leads for impedance (610 ± 259 versus 583 ± 156 Ω, p = 0.93), CT (2.0 ± 1.3 versus 1.8 ± 1.3 V, p = 0.28), or ET (7.1 ± 12.5 versus 6.8 ± 18.1 µJ, p = 0.29). Compared to endocardial leads, ventricular epicardial leads were associated with temporal decrease in impedance and increase in ET. Regarding clinical outcomes, epicardial leads had higher rates of failure but similar generator longevity in comparison to endocardial leads. Ventricular epicardial leads were associated with temporal decrease in impedance and increase in ET. Epicardial leads had a higher rate of failure but similar generator longevity compared to endocardial leads.

Abstract
In patients with a functionally univentricular heart, the Fontan strategy achieves separation of the systemic and pulmonary circulation and reduction of ventricular volume overload. Contemporary modifications of surgical techniques have significantly improved survival. However, the resulting Fontan physiology is associated with high morbidity. In this review, we discuss the state of the art of the Fontan strategy by assessing survival and risk factors for mortality. Complications of the Fontan circulation, such as cardiac arrhythmia, thromboembolism, and protein-losing enteropathy, are discussed. Common surgical and catheter-based interventions following Fontan completion are outlined. We describe functional status measurements such as quality of life and developmental outcomes in the contemporary Fontan patient. The current role of drug therapy in the Fontan patient is explored. Furthermore, we assess the current use and outcomes of mechanical circulatory support in the Fontan circulation and novel surgical innovations. Despite large improvements in outcomes for contemporary Fontan patients, a large burden of disease exists in this patient population. Continued efforts to improve outcomes are warranted. Several remaining challenges in the Fontan field are outlined.

Abstract
OBJECTIVE More patients with Fontan physiology are reaching adulthood. The purpose of this meta-analysis was to evaluate the late outcomes of patients palliated with Fontan procedure and to assess the risk factors for mortality. METHODS PubMed, Embase and Web of Science were queried to retrieve observational studies of survival in patients following the Fontan procedure with ≥5 years of follow-up. A random-effects model was used to determine pooled survival estimates at 5, 10 and 15 years. Meta-regression was used to assess potential moderators for death. RESULTS Nineteen articles with a total of 5859 patients were included. The weighted mean follow-up time was 8.94±2.64 years with overall 8.3% deaths and 1.5% transplants. Pooled survival estimates at 5, 10 and 15 years were 90.7%, 87.2% and 87.5%, respectively; and 88.4%, 85.7% and 84.1%, respectively, for studies that included all three time intervals (n=4). Earliest surgical year included in the study, proportion of atriopulmonary connections versus extracardiac conduit or lateral tunnel, and older age at Fontan were associated with higher rates of death, but ventricular morphology was not. Protein-losing enteropathy, reoperation and pacemaker insertion were reported in 2.1%, 5.6% and 6.8% patients, respectively. CONCLUSIONS Survival following the Fontan procedure has improved with time and is influenced by Fontan type and age at the time of Fontan. At a mean follow-up of 8.9 years, there was no significant association between survival and ventricular morphology, not taking into account the mortality prior to Fontan.
