Patient-reported outcome measures are commonly used to evaluate the effectiveness of treatments. CHD remains the most common congenital malformation. There has been a gradual shift in evaluating the outcome of surgery for CHD from mortality to morbidity and now to self-reported outcomes.

We aimed to review studies assessing patient-reported outcome measures as a useful marker of outcome for patients, both children and adults, who underwent surgery for CHD.

A systematic database search was conducted of original articles that explored the application of patient-reported outcome measures in the CHD surgical setting in PubMed and SCOPUS from inception to February 2022.

Our search yielded 1511 papers, of which six studies were included in this review after screening abstract and full-text, with a total sample size of 5734 patients. The main areas of discussion were the utility of patient-reported outcome measures, determinants of patient-reported outcome measures, and the need for a congenital cardiac surgery-specific patient-reported outcome measure for paediatric patients and their parents/guardians and adult patients.

This systematic review reports the use of patient-reported outcome measures to be a useful indicator to gain insight into the patients’ perspective to provide holistic and patient-centred management. However, further studies are required to assess the utility of patient-reported outcome measures in a congenital cardiac surgical setting.

Infants with truncus arteriosus typically undergo repair by repurposing the truncal valve as the neo-aortic valve and using a valved conduit homograft for the neo-pulmonary valve. In cases where the native truncal valve is too insufficient for repair, it is replaced, but this is a rare occurrence with a paucity of data, especially in the infant population. Here, we conduct a meta-analysis to better understand the outcomes of infant truncal valve replacement during the primary repair of truncus arteriosus.

We systematically reviewed PubMed, Scopus, and CINAHL for all studies reporting infant (<12 months) truncus arteriosus outcomes between 1974 and 2021. Exclusion criteria were studies which did not report truncal valve replacement outcomes separately. Data extracted included valve replacement type, mortality, and reintervention. Our primary outcome was early mortality, and our secondary outcomes were late mortality and reintervention rates.

Sixteen studies with 41 infants who underwent truncal valve replacement were included. The truncal valve replacement types were homografts (68.8%), mechanical valves (28.1%), and bioprosthetic valves (3.1%). Overall early mortality was 49.4% (95% CI: 28.4–70.5). The pooled late mortality rate was 15.3%/year (95% CI: 5.8–40.7). The overall rate of truncal valve reintervention was 21.7%/year (95% CI: 8.4–55.7).

Infant truncal valve replacement has poor early and late mortality as well as high rates of reintervention. Truncal valve replacement therefore remains an unsolved problem in congenital cardiac surgery. Innovations in congenital cardiac surgery, such as partial heart transplantation, are required to address this.

Congenital Heart Defects are the most common abnormalities at birth, resulting in many short- and long-term consequences.

In patients with transposition of the great arteries, surgical correction may achieve definitive treatment, so a thorough knowledge of the long-term outcomes, particularly neurodevelopment outcomes, is essential. Therefore, we conducted a systematic review and meta-analysis to study the neurodevelopment outcomes in the first 5 years of the life of children submitted to corrective surgery for transposition of the great arteries in the neonatal period.

A total of 17 studies from 18 reports were included, assessing 809 individuals with surgically corrected transposition of the great arteries. The neurodevelopmental outcomes were assessed with the Bayley Scales of Infant and Toddler Development (BSID) and the Wechsler Intelligence Scale for Children (WISC).

Mean Mental Development Index (MDI) and Psychomotor Development Index (PDI) were within the average values from 1 to 3 years of age, although the proportion of children scoring more than 1 standard deviation below the mean in PDI, MDI, motor, and language composite scores was significantly higher than in the general population. From 4 to 5 years, mean full-scale global intelligence quotient (IQ), verbal IQ, and performance IQ scores did not differ significantly from the general population.

This study revealed neurodevelopment scores within the normal range at 5 years of age in children submitted to corrective surgery for transposition of the great arteries in the neonatal period. However, these early outcomes may not adequately predict long-term outcomes. Further studies are needed to identify specific risk factors and early markers of later impairment to guide the establishment of early interventions.

The indications, timing, and results of the so-called “one-and-a-half ventricle repair”, as a surgical alternative to the creation of the Fontan circulation, or high-risk biventricular repair, currently remain nebulous. We aimed to clarify these issues.

We reviewed a total of 201 investigations, assessing selection of candidates, the need for atrial septal fenestration, the fate of an unligated azygos vein and free pulmonary regurgitation, the concerns regarding reverse pulsatile flow in the superior caval vein, the growth potential and function of the subpulmonary ventricle, and the role of the superior cavopulmonary connections as an interstage procedure prior to biventricular repair, or as a salvage procedure. We also assessed subsequent eligibility for conversion to biventricular repair and long-term functional results.

Reported operative mortalities ranged from 3% to 20%, depending on the era of surgical repair with 7% risk of complications due to a pulsatile superior caval vein, up to one-third incidence of supraventricular arrhythmias, and a small risk of anastomotic takedown of the superior cavopulmonary connection. Actuarial survival was between 80% and 90% at 10 years, with two-thirds of patients in good shape after 20 years. We found no reported instances of plastic bronchitis, protein-losing enteropathy, or hepatic cirrhosis.

The so-called “one-and-a-half ventricular repair”, which is better described as production of one-and-a-half circulations can be performed as a definitive palliative procedure with an acceptable risk similar to that of conversion to the Fontan circulation. The operation reduces the surgical risk for biventricular repair and reverses the Fontan paradox.

Paediatric heart failure is a common clinical syndrome that may be experienced by children with congenital heart disease (CHD) and/or cardiomyopathy. It is characterised by clinical signs/symptoms which reflect the underlying pathophysiology based on one of three main clinical states: Pulmonary over-circulation, pressure overload, and ventricular failure. Current diagnosis relies on clinical assessment and echocardiogram imaging as cardiac biomarkers has been predominantly scientific to date. This review provides a comprehensive overview of paediatric heart failure pathophysiology and considers the available evidence for cardiac biomarkers in this setting.

A literature review was completed using MEDLINE ALL, EMBASE, and PubMed on 10th November, 2022. Search terms included biomarkers, heart failure, heart defects, congenital heart disease, fontan circulation, single ventricle circulation, cardiomyopathy, and child. This allowed the identification of individual cardiac biomarkers which are the focus of this review. These included NT-proBNP, MR-proANP, MR-proADM, troponin, sST2, galectin 3, and growth differentiation factor-15.

Paediatric studies have established reference ranges for NT-proBNP and troponin for children with structurally normal hearts. Of all the biomarkers reviewed, NT-proBNP appears to correlate most closely with symptoms of heart failure and ventricular dysfunction on echocardiogram. However, there remains limited longitudinal data for NT-proBNP, and no validated reference ranges for patients with CHD and/or cardiomyopathy. None of the other biomarkers reviewed were consistently superior to NT-proBNP.

Further large paediatric studies of patients with heart failure are needed to validate NT-proBNP in CHD and to evaluate the role of novel biomarkers in specific types of CHD, e.g. single ventricle physiology.

Lung function and cardiac function are naturally correlated by sharing the thoracic cage and handling the whole cardiac output sequentially. However, lung function studies are rare in patients with CHD, although results worthy of investigation could be expected. This review summarises existing studies with the lung function parameters (spirometry and body plethysmography) in CHD patients during the last decade.

A systematic review was performed in the relevant database (PubMed, Cochrane, and Scopus) in studies including paediatric and adult patients with CHD where lung parameters (spirometry, body plethysmography) were investigated from January 2010 to December 2020. Two independent reviewers evaluated the studies according to the Study Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies of the National Heart, Lung, and Blood Institute

Eight studies investigated patients with Fontan palliation including 704 patients (306 female). Four studies included patients after repaired tetralogy of Fallot examining 219 patients (103 female), with one study using double. Further six studies included 3208 (1324 female) children and adults with various CHDs. Overall, four studies were categorised as “good”, ten as “fair”, and four as “poor”. While the measurements were consistently standardised, references to calculate %predicted differed substantially across all studies. All evaluated studies showed reduced forced vital capacity in the majority of CHD patients.

Many CHD patients have a reduced forced vital capacity independent of their underlying defect. Spirometry should not only follow a standardised measure according to ATS (update 2019) but also stick to the 2012 GLI reference values

We aimed to evaluate serum soluble suppression of tumorigenicity-2 in children with congestive heart failure, to assess the diagnostic and prognostic values of soluble suppression of tumorigenicity-2 in these patients, and to correlate its levels with various clinical and echocardiographic data.

We included 60 children with congestive heart failure as the patient group. Sixty healthy children of matched age and sex served as the control group. Patients were evaluated clinically and by echocardiography. Serum level of suppression of tumorigenicity-2 was measured for patients at admission. All patients were followed up for death or readmission for a period of one year.

Soluble suppression of tumorigenicity-2 was significantly higher in children with congestive heart failure as compared to the control group. Soluble suppression of tumorigenicity-2 was significantly increased in patients with higher severity of congestive heart failure. There was a significant increase in soluble suppression of tumorigenicity-2 in patients with bad prognosis compared to those with good prognosis. There was a significant positive correlation between soluble suppression of tumorigenicity-2 and respiratory rate, heart rate, and clinical stage of congenital heart failure, while there was a significant negative correlation between soluble suppression of tumorigenicity-2 and left ventricular systolic and diastolic function. The best cut-off of soluble suppression of tumorigenicity-2 to diagnose congestive heart failure was > 3.6 with 87% sensitivity and 79% specificity. The cut-off point of soluble suppression of tumorigenicity-2 to diagnose congestive heart failure in children was ≥ 31.56 ng/ml, with 95% sensitivity and 91.37% specificity. Moreover, the cut-off point of soluble suppression of tumorigenicity-2 to predict bad prognosis in children with congestive heart failure was ≥ 255.5 ng/ml, with 92% sensitivity and 89.0% specificity.

Soluble suppression of tumorigenicity-2 is a good diagnostic and predictive biomarker in children with congestive heart failure.

Transposition of great arteries with intact ventricular septum and left ventricular outflow tract obstruction (TGA + IVS + LVOTO) is uncommon. We reviewed operations performed in patients with TGA + IVS + LVOTO in the European Congenital Heart Surgeons Association Congenital Database (ECHSA-CD).

All 109 patients with a diagnosis of TGA + IVS + LVOTO in ECHSA-CD who underwent cardiac surgery during a 21-year period (01/2000-02/2021, inclusive) were included. Preoperative variables, operative data, and postoperative outcomes were collected.

These 109 patients underwent 176 operations, including 37 (21.0%) arterial switch operations (ASO), 26 (14.2%) modified Blalock-Taussig-Thomas shunts (MBTTS), 11 (6.2%) Rastelli operations, and 13 (7.3%) other palliative operations (8 superior cavopulmonary anastomosis[es], 4 Fontan, and 1 other palliative procedure). Of 37 patients undergoing ASO, 22 had a concomitant procedure.

There were 68 (38.6%) reoperations, including 11 pacemaker procedures and 8 conduit operations. After a systemic-to-pulmonary artery shunt, reoperations included shunt reoperation (n = 4), Rastelli (n = 4), and superior cavopulmonary anastomosis (n = 3).

Overall Operative Mortality was 8.2% (9 deaths), including three following ASO, two following “Nikaidoh, Kawashima, or LV-PA conduit” procedures, and two following Rastelli. Postoperative complications occurred after 36 operations (20.4%). The most common complications were delayed sternal closure (n = 11), postoperative respiratory insufficiency requiring mechanical ventilation >7 days (n = 9), and renal failure requiring temporary dialysis (n = 8).

TGA + IVS + LVOTO is rare (109 patients in ECHSA-CD over 21 years). ASO, MBTTS, and Rastelli are the most common operations performed for TGA + IVS + LVOTO. Larger international studies with long-term follow-up are needed to better define the anatomy of the LVOTO and to determine the optimal surgical strategy.

Diversification of the medical and cardiothoracic surgical workforce represents an ongoing need. A congenital cardiac surgery shadowing programme for undergraduate students was implemented at the University of Florida Congenital Heart Center.

Students shadowing in the Congenital Heart Center from 17 December 2020 through 20 July 2021 were sent a survey through Qualtrics to evaluate the impact of their shadowing experience. The main objectives of the survey were to determine the personal relationship(s) of the students to physicians prior to shadowing, how the presence or absence of physicians in the family of a given student related to the exposure of the student to a medical setting prior to shadowing, and the interest of the students in medicine and cardiothoracic surgery prior to and after the shadowing experience. Survey responses included “Yes/No” questions, scaled responses using a Likert scale, selection lists, and free text responses. When applicable, t-tests were utilised to assess differences between student groups.

Of the 37 students who shadowed during the study period, 26 (70%) responded. Most students were female (58%, n = 15), and the mean age was 20.9 ± 2.4 years. Students spent a mean duration of 95 ± 138 hours shadowing providers as part of the shadowing programme. Likert scale ratings of interest in the professions of medicine, surgery, and cardiothoracic surgery all increased after the shadowing experience (p < 0.01). Students with a family member in medicine had more clinical exposure prior to the shadowing programme (p < 0.01).

A surgical shadowing programme at a Congenital Heart Center may have an important formative impact on the views of undergraduate students regarding potential careers in surgery and medicine. Additionally, students without family members in medicine tend to have less prior exposure to medicine and could likely benefit more from this type of shadowing programme.

Education of paediatric advanced practice providers takes a generalist approach which lacks in-depth exposure to subspecialties like paediatric cardiac intensive care. This translates into a knowledge gap related to congenital cardiac physiology and management for APPs transitioning to the paediatric cardiac ICU.

A specialised interprofessional peer-reviewed curriculum was created and distributed through the Pediatric Cardiac Intensive Care Society. This curriculum includes a textbook which is complemented by a didactic and simulation review course. Course evaluations were collected following each course, and feedback from participants was incorporated into subsequent courses. Pediatric Cardiac Intensive Care Society partnered with the Pediatric Nursing Certification Board to develop a 200-question post-assessment (exam) bank.

From December 2017 to January 2022, 12 review courses were taught at various host sites (n = 314 participants). Feedback revealed that courses improved preparedness for practice, contributed to advanced practice provider empowerment, and emphasised the importance of professional networking. 97% of attendees agreed/strongly agreed that the course improved clinical knowledge, 97% agreed/strongly agreed that the course improved ability to care for patients, and 88% agreed/strongly agreed that the course improved confidence to practice. 49% of participants rated the course as extremely effective, 42% very effective, 6% moderately effective, and 3% as only slightly effective.

A standardised subspecialty curriculum dedicated to advanced practice provider practice in cardiac intensive care was needed to improve knowledge, advance practice, and empower APPs managing critically ill patients in the cardiac ICU. The developed curriculum provides standardised learning, increasing advanced practice provider knowledge acquisition, and confidence to practice.

Double-orifice mitral valve or left atrioventricular valve is a rare congenital cardiac anomaly that may be associated with an atrioventricular septal defect. The surgical management of double-orifice mitral valve/double-orifice left atrioventricular valve with atrioventricular septal defect is highly challenging with acceptable clinical outcomes. This meta-analysis is aimed to evaluate the surgical outcomes of double-orifice mitral valve/double-orifice left atrioventricular valve repair in patients with atrioventricular septal defect.

A total of eight studies were retrieved from the literature by searching through PubMed, Google Scholar, Embase, and Cochrane databases. Using Bayesian hierarchical models, we estimated the pooled proportion of incidence of double-orifice mitral valve/double-orifice left atrioventricular valve with atrioventricular septal defect as 4.88% in patients who underwent surgical repair (7 studies; 3295 patients; 95% credible interval [CI] 4.2–5.7%). As compared to pre-operative regurgitation, the pooled proportions of post-operative regurgitation were significantly low in patients with moderate status: 5.1 versus 26.39% and severe status: 5.7 versus 29.38% [8 studies; 171 patients]. Moreover, the heterogeneity test revealed consistency in the data (p < 0.05). Lastly, the pooled estimated proportions of early and late mortality following surgical interventions were low, that is, 5 and 7.4%, respectively.

The surgical management of moderate to severe regurgitation showed corrective benefits post-operatively and was associated with low incidence of early mortality and re-operation.
