Long-Term Effects of Child Early Surgical Ventricular Septal Defect Repair on Maternal Stress.

The ventricular septal defect (VSD) represents the most common congenital heart defect (CHD). The diagnosis of and cardiac surgery for their child's VSD are highly stressful experiences for parents; especially mothers, who are at risk of developing long-lasting stress-related symptoms. This study examined long-term alterations in maternal stress including self-reported psychological and biophysiological stress levels in a case-control design. We investigated 24 mothers of children with an isolated, surgically corrected VSD compared to non-affected controls. Maternal self-reports on psychopathology, everyday stress, parenting stress and hair cortisol concentrations (HCC) were measured during children's primary school age (6-9 years, t1) and early adolescence (10-14 years, t2). In maternal self-reports, psychopathology and stress symptoms in the VSD-group and controls were comparable at t1, whereas at t2, mothers in the VSD-group even showed a decrease in psychopathology. Maternal HCC levels in the VSD-group were significantly lower (hypocortisolism) than HCC levels of controls at t1. This effect was no longer observed at t2 reflecting an approximation of HCC levels in the VSD-group to controls' levels. This study highlights the potential for improved stress hormone balance and psychological well-being in mothers following their child's surgical VSD repair. However, the need for parent-centered interventions is discussed, particularly during peri-operative phases and in early child developmental stages.

Becoming a Teenager after Early Surgical Ventricular Septal Defect (VSD) Repair: Longitudinal Biopsychological Data on Mental Health and Maternal Involvement.

Beside somatic strains of congenital heart diseases (CHD), affected children often show developmental impairments in the long term. Ventricular septal defect (VSD) is the most common congenital heart defect and early surgical repair is associated with positive somatic outcomes. However, psychological adjustment is of lifelong relevance. We investigated 24 children with a surgically-corrected isolated VSD and their mothers from primary school (6-9 years) to adolescence (10-14 years) and compared them to controls. Both times, mothers reported child internalizing/externalizing problems, mothers and children rated child quality of life, and children performed neurodevelopmental tests. Adolescents also rated internalizing/externalizing problems themselves, and their hair cortisol levels were analyzed. Maternal anxiety and proactive parenting behavior were considered as moderators. Results revealed no group differences in child neurodevelopment (language, cognition), externalizing problems, and cortisol levels at any time. In reports from mothers, internalizing problems (depression, anxiety) were elevated in children with a VSD at both times-when mothers reported anxiety symptoms themselves. In adolescent reports, VSD patients' quality of life was increased and internalizing problems were decreased-proactive parenting behavior went along with decreased symptoms in VSD-affected adolescents and with increased symptoms in controls. The findings pronounce the crucial role of parenting behavior and the influence of maternal anxieties on child mental health after surgical VSD repair and might highlight the need for parent-centered interventions.

Growth of hypoplastic mitral valves in hypoplastic left heart complex and similar constellations after anatomical left superior vena cava correction.

OBJECTIVES: Left superior vena cava (LSVC)-related obstruction of mitral inflow is a rare finding in patients with complex cardiac anomalies like hypoplastic left heart complex. We report our experience by establishing a left superior to right superior caval vein continuity (innominate vein creation by direct LSVC-right superior vena cava end-to-side-anastomosis), and coronary sinus unroofing if indicated for LSVC-related mitral inflow obstruction. METHODS: Nineteen patients (median age: 1.0 ± 0.3 years; range: 7 days-4.8 years) underwent anatomical correction of LSVC without the use of foreign material in conjunction with repair or palliation of congenital anomalies in a single centre between April 2015 and November 2019. Indications for the procedure were LSVC-related obstruction of left ventricular inflow due to a dilated coronary sinus. Additional procedures included mitral (n = 7) or atrioventricular (n = 3) valve surgery, right ventricular to pulmonary artery conduit (n = 3), first stage palliation (n = 3) or biventricular repair (n = 5) of hypoplastic left heart complex. Three patients needed secondary mitral valve replacement (n = 3). RESULTS: All LSVC or coronary sinus-related obstructions were effectively relieved. No patient died early, 2 patients died late after the procedure. One patient needed stenting of the superior vena cava below the unobstructed cephalad vein anastomosis at the former right superior vena cava-cannulation-site. Follow-up was complete and demonstrated an 89.5% survival after 2.5 ± 0.4 years. Innominate vein patency was 100% documented by echocardiography (n = 19), cardiac catheterization (n = 6) or both. Mean mitral valve z-scores before the operation were -1.7 ± 0.2 (range -3.8 to 0.3) and increased to 0.7 ± 0.2 (range -0.7 to 1.9) after LSVC repair. CONCLUSIONS: Anatomical correction by surgical creation of an innominate vein is an effective method to relieve LSVC-related obstructions and promotes mitral valvar growth. Mitral ring sizes were at least normalized after surgery at the time of discharge. Further prospective follow-up studies to evaluate the growth potential of left-sided heart structures by reporting cardiac z-scores are needed to evaluate the true impact of coronary sinus unroofing.

Child neurodevelopment and mental health after surgical ventricular septal defect repair: risk and protective factors.

AIM: This case-control study examined the long-term consequences of surgical correction for ventricular septal defect (VSD; the most common congenital heart defect) in infancy. It assessed children who had undergone VSD surgery and the factors related to maternal conditions, surgery, and hospital stay. METHOD: Thirty-nine children (23 females, 16 males; age range 6y 1mo-9y 7mo [mean 7y 4mo, SD 1y]) with repaired isolated, non-syndromic, non-genetic VSD were compared with 39 typically developing children (22 females, 17 males; age range 6y-9y 2mo [mean 7y 3mo, SD 10mo]). The children completed behavioural tests of neurodevelopment and a quality of life (QoL) questionnaire. Mothers rated children's emotional/behavioural symptoms and QoL. Measures of maternal parenting behaviour and psychopathology were treated as moderators. RESULTS: Affected children showed reduced language skills (p=0.002) unless mothers reported high parenting behaviour subscale scores (p=0.04). Children's anxiety symptoms were elevated when mothers had anxiety symptoms (p=0.01). Longer hospital stay was associated with lower intelligence (p=0.003) and psychomotor scores (p=0.006). Longer scars predicted elevated child anxiety (p=0.008), and age at surgery and QoL were inversely related (p=0.01). INTERPRETATION: Impairments could be mitigated if VSD repair was performed early in life with a relatively small scar and uncomplicated hospital stay. This outcome depends on maternal parenting behaviour and anxiety symptoms. WHAT THIS PAPER ADDS: Children's cognitive and psychomotor development after surgical ventricular septal defect repair was unimpaired. Children showed no mental health restrictions when their mothers reported few anxiety symptoms themselves. Language impairments might be preventable by pro-active parenting. The outcome also depends on variables related to surgery and hospital stay.

Systemic-to-pulmonary artery shunting using heparin-bonded grafts.

OBJECTIVES: Systemic-to-pulmonary artery shunting remains an important palliative procedure in the staged management of complex congenital heart defects. The use of heparin-bonded polytetrafluoroethylene shunts (HBPSs) should enhance graft patency. This study aimed to review the single-centre experience using HBPS in the context of congenital cardiac surgery. METHODS: The records of 51 patients treated using HBPS between 2010 and 2016 were retrospectively reviewed. The median age and weight of the patients were 8 (range 3-83) days and 3.2 (range 1.8-5.7) kg, respectively. Selected shunt size was 3.5 mm in all patients. Fourteen (27.5%) patients were planned for future biventricular repair and 37 (72.5%) patients underwent univentricular pathway. Shunt modifications included central aortopulmonary shunts (n = 35; 68.6%) and modified Blalock-Taussig shunts (n = 16; 31.4%). Shunt patency and survival until estimated 2nd procedure were calculated using the Kaplan-Meier method. RESULTS: Shunt patency was 90 ± 4% after a median duration of 133 (range 0-315) days. Early mortality (30 days) was 3.9% (n = 2). Another 3 patients died during their hospital stay. All the deceased patients had univentricular morphology, and the cause of death was not shunt related in all patients. Five patients developed subtotal HBPS thrombosis intraoperatively (n = 3), early postoperatively after 3 days (n = 1, 1.9%) or late after 41 days (n = 1, 1.9%). Treatment of those patients comprised right ventricular outflow tract opening (n = 2, 3.9%) or new shunting (n = 3, 5.9%). Elective shunt takedown was performed during corrective surgery (n = 10, 19.6%), bidirectional Glenn (n = 25, 49%) or shunt replacement (n = 5, 9.8%). At the end of follow-up, 1 (1.9%) patient had still an HBPS in situ. The survival rate until planned 2nd procedure was 87 ± 6% in univentricular patients and 100% in biventricular patients (P = 0.17). CONCLUSIONS: The use of HBPS in the context of palliative heart surgery is safe and seems to warrant a long-term patency of systemic-to-pulmonary shunts. However, by acting on only 1 site of Virchow's triad, shunt thrombosis, occurring predominantly early, cannot be totally excluded.

Long-term Associations of an Early Corrected Ventricular Septal Defect and Stress Systems of Child and Mother at Primary School Age.

INTRODUCTION: Ventricular septal defect (VSD) is the most common congenital heart defect, with larger VSDs typically being corrected with an open-heart surgery during infancy. Long-term consequences of a VSD-corrective surgery on stress systems of child and mother are still unknown. The aim of the present study is to investigate the associations of an early corrected VSD and diurnal cortisol release of child and mother. METHODS: 26 children (12 boys) between 6 and 9 years old, who underwent surgery for an isolated VSD within the first 3 years of life, and their mothers participated in the study. Their diurnal cortisol profiles were compared to a sex-, age-, and socioeconomic status-matched healthy control group. Within the VSD group, associations between cortisol and characteristics of surgery and hospitalization were investigated. Child and mother psychopathological symptoms were considered as a possible interfering mechanism of altered cortisol profiles. RESULTS: Diurnal cortisol profiles of children with an early corrected VSD did not differ from those of controls. However, mothers of affected children exhibited higher cortisol levels in the morning (p < 0.001, [Formula: see text]) and a steeper diurnal cortisol slope (p = 0.016, [Formula: see text]) than mothers of healthy children. CONCLUSION: Results indicate a favorable development of children with an early corrected VSD, in terms of comparable diurnal cortisol profiles with healthy controls, according to a comparable mother-rated psychopathology. Mothers of affected children reveal altered diurnal cortisol levels, without differences in self-rated psychopathology. This divergence should be clarified in future research.

Performance of stented biological valves for right ventricular outflow tract reconstruction.

OBJECTIVES: This retrospective single-centre review presents mid- and long-term results of stented biological valves (SBVs) in the pulmonary position. METHODS: Fifty-two SBVs (17 Carpentier-Edwards Supraannular; 13 Carpentier-Edwards Perimount; 12 St. Jude Medical Trifecta; 4 Sorin Mitroflow; 4 Sorin Soprano; 2 Sorin More) were implanted between 2000 and 2015. The median valve size, patient age and weight were 23 mm (range 19-27), 22.8 years (range 5-77) and 62.0 kg (range 14-110), respectively. The main cardiac diagnosis was tetralogy of Fallot in 26 patients (50%). Forty-four patients (85%) had previous cardiac surgery; 12 patients (23%) had previous conduit or biological valve replacement. Valve degeneration was defined as a valvular peak pressure gradient >50 mmHg or pulmonary valve regurgitation more than moderate. RESULTS: The mean follow-up was 7.9 ± 5.5 years. Two patients died after 5.8 and 6.1 years of causes not related to SBVs. Eleven SBVs (21%) had to be replaced surgically (n = 6) or interventionally (n = 5) after 9.0 ± 4.1 years due to valve degeneration (n = 8), endocarditis (n = 2) or right ventricular dysfunction (n = 1). The rates of freedom from valve replacement were 100%, 92% [95% confidence interval (CI) 79-97], 81% (CI 64-91) and 60% (CI 40-78) after 1, 5, 10 and 15 years, respectively. Successful interventional valve-in-valve implantation resulted in 100% freedom from surgical valve replacement in all patients older than 19.1 years. Multivariate analysis identified patient age <19.1 years (P = 0.007) as a risk factor for earlier valve degeneration. CONCLUSIONS: SBVs in the pulmonary position showed encouraging long-term results in mature patients. The design of SBVs enables interventional valve implantation, postponing the need for reoperation.

Pediatric Extracorporeal Life Support Using a Third Generation Diagonal Pump.

This study reports a single-centre experience of the Medos Deltastream diagonal-pump (DP3) for extracorporeal cardiac, pulmonary, or combined support in a single-center pediatric cohort. Twenty-seven consecutive patients with 28 runs of the DP3 between January 2013 and June 2014 were included for analysis. Median patient age, weight, and duration of support were 278 days (range: 0 days-14.2 years), 7.2 kg (range: 2.5-39 kg), and 8 days (range: 2-69 days). Midline sternotomy (n = 20, 71.4%) or cervical approaches (n = 8, 28.6%) were used for cannulation. The DP3 was employed for either veno-arterial extracorporeal life support (ECLS, n = 16), veno-venous extracorporeal membrane oxygenation (ECMO, n = 5), or ventricular assist devices (right ventricular assist device [RVAD], n = 1; left ventricular assist device [LVAD], n = 1; and univentricular assist device [UNIVAD], n = 5). Three patients initially supported with ECLS were switched to UNIVAD and one patient with UNIVAD was changed to ECLS. Required flow for neonates (n = 8) ranged between 0.2 and 0.75 L/min. Irreversible pump damage occurred in one patient during deairing after air block. Successful weaning, 30 day and hospital survival were 89.3% (n = 25), 85.7% (n = 24), and 71.4% (n = 20). All patients on UNIVAD, who did not require further extracorporeal respiratory assist, survived. In conclusion, the DP3 can be used for individual patient demands and adapted to their most suitable method of support. Meticulous flow adjustments render this pump highly effective for extracorporeal support particularly in pediatric patients.

Hemopatch Application for Ventricular Wall Laceration in Redo Cardiac Surgical Procedures.

As survival among patients with complex congenital heart disease continues to improve, long-term survivors frequently require redo surgical procedures, with potentially escalating technical difficulty and bleeding risk. This report describes our experience with a new hemostatic pad, Hemopatch (Baxter Deutschland GmbH, Unterschleissheim, Germany) in redo cardiac surgery.

Early stage 2 palliation is crucial in patients with a right-ventricle-to-pulmonary-artery conduit.

BACKGROUND: Improved survival after Norwood stage 1 palliation is giving more patients the opportunity to reach stage 2 palliation; thus, more patients are exposed to the risk of interstage death. METHODS: A single-center review of patients who underwent stage 1 palliation from January 1998 to December 2007 (n = 58) was performed. Pulmonary blood flow was established either by a modified Blalock-Taussig-shunt (mBTS, n = 33) or a right ventricle-to-pulmonary artery conduit (RVPAC, n = 25). RESULTS: Hospital, interstage, and 1-year survival was not significantly different between groups. However, Kaplan-Meier survival analysis reflected a significantly higher survival probability for RVPAC patients until the age of 120 days (RVAPC, 92% ± 5% [standard error of the mean]; 95% confidence interval, 82 to 100; mBTS, 63% ± 9%; 95% confidence interval, 48 to 82; p = 0.01). During a 1-year follow-up, all 11 nonsurvivors with mBTS died at an age younger than 120 days, including 2 patients with early stage 2 palliation. In contrast, besides 2 early deaths, all RVPAC patients (n = 5) showed later attrition at an age older than 120 days while awaiting stage 2 palliation. Interstage death occurred significantly later among RVPAC patients (RVPAC, 146 ± 60 days versus mBTS, 81 ± 23 days; p = 0.01). After stage 2 palliation, all patients with RVPAC survived, including 7 patients with surgery at an age younger than 120 days. All interstage and late deaths were related to compromising cardiac lesions with no statistical difference between groups. CONCLUSIONS: After Norwood stage 1 palliation, survival was improved with RVPAC for the first 4 months. However, a loss of the favorable primary outcome was present by delaying stage 2 palliation beyond the age of 120 days. Progressive volume load as a result of conduit regurgitation may play a crucial role for later attrition. Residual lesions should be addressed early to preserve cardiac function.
