Combining Congenital Heart Surgical and Interventional Cardiology Outcome Data in a Single Database: The Development of a Patient-Centered Collaboration of the European Congenital Heart Surgeons Association (ECHSA) and the Association for European Paediatric and Congenital Cardiology (AEPC).

The European Congenital Heart Surgeons Association (ECHSA) Congenital Database (CD) is the second largest clinical pediatric and congenital cardiac surgical database in the world and the largest in Europe, where various smaller national or regional databases exist. Despite the dramatic increase in interventional cardiology procedures over recent years, only scattered national or regional databases of such procedures exist in Europe. Most importantly, no congenital cardiac database exists in the world that seamlessly combines both surgical and interventional cardiology data on an international level; therefore, the outcomes of surgical and interventional procedures performed on the same or similar patients cannot easily be tracked, assessed, and analyzed. In order to fill this important gap in our capability to gather and analyze information on our common patients, ECHSA and The Association for European Paediatric and Congenital Cardiology (AEPC) have embarked on a collaborative effort to expand the ECHSA-CD with a new module designed to capture data about interventional cardiology procedures. The purpose of this manuscript is to describe the concept, the structure, and the function of the new AEPC Interventional Cardiology Part of the ECHSA-CD, as well as the potentially valuable synergies provided by the shared interventional and surgical analyses of outcomes of patients. The new AEPC Interventional Cardiology Part of the ECHSA-CD will allow centers to have access to robust surgical and transcatheter outcome data from their own center, as well as robust national and international aggregate outcome data for benchmarking. Each contributing center or department will have access to their own data, as well as aggregate data from the AEPC Interventional Cardiology Part of the ECHSA-CD. The new AEPC Interventional Cardiology Part of the ECHSA-CD will allow cardiology centers to have access to aggregate cardiology data, just as surgical centers already have access to aggregate surgical data. Comparison of surgical and catheter interventional outcomes could potentially strengthen decision processes. A study of the wealth of information collected in the database could potentially also contribute toward improved early and late survival, as well as enhanced quality of life of patients with pediatric and/or congenital heart disease treated with surgery and interventional cardiac catheterization across Europe and the world.

TGA + IVS + LVOTO: patterns of practice and outcomes.

PURPOSE: 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). METHODS: 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. RESULTS: 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). CONCLUSION: 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.

Ten Years of Data Verification: The European Congenital Heart Surgeons Association Congenital Database Audits.

BACKGROUND: Congenital heart surgery databases are tools for internal programmatic evaluation, benchmarking institutional results to multi-institutional aggregate data, and research. Therefore, it is essential to ensure the completeness and accuracy of data. This study analyzes the results of ten years of on-site source data verification of the European Congenital Heart Surgeons Association Congenital Heart Surgery Database (ECHSA CHSD). METHODS: All data forms verified between 2009 and 2018 were analyzed. The data form consists of 12 data elements: dates of birth, admission, surgery, discharge, and death; weight; case category; cardiopulmonary bypass time; aortic cross-clamp time; validation rules; diagnoses; and procedures. Descriptive data calculation and rates of completeness and accuracy were determined. The trend of error rate of seven centers with ≥5 visits was analyzed. RESULTS: Sixty-nine on-site verification visits took place at 17 centers. A total of 26,245 cases were verified; 2,841 of these 26,245 cases (10.8%) showed an error. The total mean error rate of centers for all years was 12.3 ± 2.1%. Rates of completeness and accuracy were 99% and 89.2%, respectively. Coded diagnoses and procedure analysis revealed that 716 (2.7%) and 456 (1.7%) datasets were incorrect, respectively. Rates of completeness and accuracy of dates were 100%, and 97.1%, respectively. Validation fields showed no errors. CONCLUSION: Source data verification is an appropriate tool to determine completeness and accuracy of data. The ECHSA CHSD verification analysis of a ten-year period showed a high level of completeness and accuracy. The verified data of the ECHSA CHSD are well-suited for benchmarking and research.

Prophylactic Peritoneal Catheter Placement in Congenital Cardiac Surgery.

The use of a peritoneal catheter in selected patients, in relation to the congenital heart defect and surgical procedure, may improve postoperative fluid balance and recovery. The peritoneal catheter allows to either drain ascites passively out of the peritoneal cavity or utilize cycles of peritoneal dialysis. However, potential benefits contrast with risk. This article provides a step-by-step guide on how to implant a peritoneal catheter in the operating room after cardiac surgery, or insert it at the bedside in the ICU, to minimize the risk of complications such as bowel perforation, herniation or omental adhesions.

Copeptin: Prognostic Relevance as a Perioperative Marker in Pediatric Cardiac Surgery.

BACKGROUND: Copeptin is a cleavage product of vasopressin. This study aimed to figure out if copeptin would be a suitable biomarker in patients with congenital heart disease in the postoperative course. METHODS: The primary outcome endpoint of this study was the change in copeptin concentration perioperatively in patients with congenital heart disease after surgery, with the use of a cardiopulmonary bypass. Three blood samples were taken from 81 patients up to 6 years of age in order to evaluate changes in copeptin concentration. RESULTS: Significant increase of copeptin concentration was shown between the first and second blood draws as well as between the first and third blood draws (Ps < .001). Additionally, positive and significant correlations (r ≥ .27) between the cardiopulmonary bypass times, The Society of Thoracic Surgeons and European Association for Cardio-Thoracic Surgery mortality category, the inotropic score, the duration of mechanical ventilation, the length of stay at the intensive care unit (ICU), the length of stay at the hospital, and the preoperative as well as the ICU copeptin levels were found. CONCLUSIONS: Copeptin showed a tendency to predict the clinical outcome of patients after congenital heart surgery. Patients with higher copeptin levels underwent more complex procedures, had longer cardiopulmonary bypass times, required more catecholamine support, needed longer time of invasive ventilation, and had longer overall stay and ICU stay.

Pediatric Cardiac Surgical Patterns of Practice and Outcomes in Japan and Europe.

OBJECTIVES: The Japan Cardiovascular Surgery Database-Congenital section (JCVSD-Congenital) and the European Congenital Heart Surgeons Association (ECHSA) Congenital Heart Surgery Database (CHSD) share the same nomenclature. We aimed at comparing congenital cardiac surgical patterns of practice and outcomes in Japan and Europe using the JCVSD-Congenital and ECHSA-CHSD. METHODS AND RESULTS: We examined Japanese (120 units, 63,365 operations) and European (96 units, 90,098 operations) data in JCVSD-Congenital and ECHSA-CHSD from 2011 to 2017. Patients' age and weight, periprocedural times, mortality at hospital discharge, and postoperative length of stay were calculated for ten benchmark operations. There was a significantly higher proportion of ventricular septal defect closures and Glenn operations and a significantly lower proportion of coarctation repairs, tetralogy of Fallot repairs, atrioventricular septal defect repairs, arterial switch operations, truncus repairs, Norwood operations, and Fontan operations in JCVSD-Congenital compared to ECHSA-CHSD. Postoperative length of stay was significantly longer following all benchmark operations in JCVSD-Congenital compared to ECHSA-CHSD. Mean STAT mortality score (Society of Thoracic Surgeons European Association for Cardio-Thoracic Surgery mortality score) was significantly higher in JCVSD-Congenital (0.78) compared to ECHSA-CHSD (0.71). Mortality at hospital discharge was significantly lower in JCVSD-Congenital (4.2%) compared to ECHSA-CHSD (6.0%, P < .001). CONCLUSIONS: The distribution of the benchmark procedures and age at the time of surgery differ between Japan and Europe. Postoperative length of stay is longer, and the mean complexity is higher in Japan compared to European data. These comparisons of patterns of practice and outcomes demonstrate opportunities for continuing bidirectional transcontinental collaboration and quality improvement.

Current Status of Training and Certification for Congenital Heart Surgery Around the World: Proceedings of the Meetings of the Global Council on Education for Congenital Heart Surgery of the World Society for Pediatric and Congenital Heart Surgery.

The optimal training of the highly specialized congenital heart surgeon is a long and complex process, which is a significant challenge in most parts of the world. The World Society for Pediatric and Congenital Heart Surgery (WSPCHS) has established the Global Council on Education for Congenital Heart Surgery as a nonprofit organization with the goal of assessing current training and certification and ultimately establishing standardized criteria for the training, evaluation, and certification of congenital heart surgeons around the world. The Global Council and the WSPCHS have reviewed the present status of training and certification for congenital cardiac surgery around the world. There is currently lack of consensus and standardized criteria for training in congenital heart surgery, with significant disparity between continents and countries. This represents significant obstacles to international job mobility of competent congenital heart surgeons and to the efforts to improve the quality of care for patients with Congenital Heart Disease worldwide. The purpose of this article is to summarize and document the present state of training and certification in congenital heart surgery around the world.

Anomalous left coronary artery from pulmonary artery repair: Outcomes from the European Congenital Heart Surgeons Association Database.

INTRODUCTION: We sought to determine the surgical outcomes of patients with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) enrolled in the European Congenital Heart Surgeons Association (ECHSA) database. MATERIALS AND METHODS: From 1999 to 2019, 907 patients with ALCAPA underwent surgical repair and were included in the current study. The primary outcome was in-hospital mortality. Secondary outcomes included frequency and results of concomitant mitral valve surgery and postoperative mechanical circulatory support (MCS). RESULTS: The overall in-hospital mortality was 6% (54/907) and was significantly higher in neonates (p = .01), patients with lower body surface area (BSA) (p = .01), and those requiring postoperative MCS (p = .001). Associated mitral valve surgery was performed in 144 patients (15.9%) and was associated with longer cardiopulmonary bypass (CPB) and aortic cross-clamp times (AOX) (p ≤ .0001) but was not significantly related to an increase in in-hospital mortality. Postoperative MCS was required in 66 patients (7.3%). These patients were younger (p ≤ .001), had a lower BSA (p ≤ .001), and required a longer CPB (p ≤ .001) and AOX time (p ≤ .001). CONCLUSIONS: ALCAPA repair can be achieved successfully, and with low surgical risk. Concomitant mitral valve procedures can be performed without increasing operative mortality. The use of MCS remains a valuable option, especially in younger patients.

Direct postoperative protein S100B and NIRS monitoring in infants after pediatric cardiac surgery enrich early mortality assessment at the PICU.

BACKGROUND: Neuromonitoring using plasmatic biomarkers such as S100B and near-infrared spectroscopy (NIRS) represents a standard procedure for detecting cerebral damage after cardiac surgery. Their use in pediatric clinical assessment, however, is negligible. OBJECTIVES: The goal of this study was to evaluate the predictive role of S100B levels and cerebral oxygenation in postoperative pediatric cardiac patients for survival and potential cerebral injuries. METHODS: A retrospective cohort study of infants after cardiac surgery. Primary outcome was survival until discharge. Intra/postoperative vital signs and laboratory data were measured and statistically analyzed. RESULTS: Seven out of 226 infants were non-survivors. Non-survivors had significantly lower cerebral saturation than survivors, as well as elevated S100B values at admission, associated with lower arterial pressure and higher serum lactate levels. CONCLUSION: Although significant differences of S100B and crO2 values between survivors and non-survivors were found, no critical thresholds could be established from the data. Nevertheless, changes from the norm in these parameters should raise awareness for critical clinical development.

Surgical stented transcatheter valve-in-valve implantation in atrioventricular position in children.

The Melody valve (Medtronic, Minneapolis, MN, USA) is a stented bovine jugular vein graft that was primarily approved for transcatheter implantation in a pulmonary valve position. The prosthetic valve can also be implanted in an atrioventricular position in infants and young children, and in these cases it must be modified appropriately.  In this tutorial we demonstrate the surgical preparation of a stented transcatheter Melody valve for implantation in the atrioventricular position. Additionally, we present a safe and effective method for surgical valve-in-valve implantation in a 3-year-old patient with hypoplastic left heart syndrome.

Implantation of a decellularized aortic homograft in a child.

The implantation of a decellularized aortic homograft in children and young adults has been shown to be a good alternative to existing surgical approaches. Lower risk of calcification and the potential of growth render a homograft a promising valve substitute. The child presented in this video tutorial is a 10-year-old boy diagnosed with congenital aortic stenosis which was treated by balloon valvuloplasty early in life. Current echocardiographic findings show severe aortic regurgitation and stenosis. The tutorial provides detailed insight into how to implant a decellularized aortic homograft as a total root replacement.

Implantation of the Berlin Heart EXCOR ventricular assist device.

The Berlin Heart EXCOR® is a mechanical, pulsatile ventricular assist device. The paracorporeal assist device is pneumatically driven and can be used for long-term bridging therapy of one or both ventricles (LVAD, BIVAD, RVAD). It is specifically designed for pediatric patients and can be used in neonates as well as juveniles and adults.  The infant presented in this video tutorial was diagnosed with myocarditis leading to end-stage heart failure and severe mitral valve regurgitation. A bridging therapy was indicated and a Berlin Heart EXCOR® VAD was implanted. This tutorial provides detailed insight on how to perform this procedure. In addition, a safe and effective way of extending the outflow cannula is demonstrated.

Reinforcement of the pulmonary autograft root in the Ross operation.

In this video tutorial we demonstrate our technique of root reinforcement of the pulmonary autograft in a Ross operation. This technique is being used with increasing frequently to prevent the formation of an aneurysm of the pulmonary autograft.  The patient presented in the video has a bicuspid aortic valve with severe symptomatic aortic valve stenosis and moderate regurgitation. After harvesting, the pulmonary autograft it is sized and a 3- or 5-mm oversized Valsalva vascular prosthesis is chosen for reinforcement and to prevent formation of an aneurysm. Sizing depends on the amount and thickness of muscle in the pulmonary autograft.

The Konno-Rastan procedure.

The Konno-Rastan procedure is an anterior aortoventriculoplasty that has  the aim of relieving subvalvar, valvar, and supravalvar stenosis. It can be helpful for patients with aortic stenosis at any level and also for those with a prior implanted aortic and/or mitral prosthesis.  The patient presented in this video tutorial had a history of rheumatic heart disease with previously implanted mechanical prostheses in the aortic as well as the mitral position. We provide detailed insight on how to perform the Konno incision safely and demonstrate the reconstruction of the aortic root, as well as the ventricular septum and the right ventricular outflow tract using a patch of bovine pericardium.
