Results of surgery for Ebstein anomaly: a multicenter study from the European Congenital Heart Surgeons Association.

OBJECTIVE: Since most centers' experience with Ebstein anomaly is limited, we sought to analyze the collective experience of participating institutions of the European Congenital Heart Surgeons Association with surgery for this rare malformation. METHODS: The records of all 150 patients (median age 6.4 years) who underwent surgery for Ebstein anomaly in the 13 participating Association centers between January 1992 and January 2005 were reviewed retrospectively. Patients with congenitally corrected transposition were excluded. RESULTS: Most patients (81%) had Ebstein disease type B or C and significant functional impairment (61% in New York Heart Association class III or IV) and 16% had prior operations. Surgical procedures (n = 179) included valve replacement (n = 60, 33.5%), valve repair (n = 49, 27.3%), 1(1/2) ventricle repair (n = 46, 25.6%), palliative shunt (n = 13, 7.26%), and other complex procedures (n = 11, 6.14%). There were 20 hospital deaths (operative mortality 13.3%) after valve replacement in 5 patients, valve repair in 3, 1(1/2) ventricle repair in 7, palliative procedures in 3, and miscellaneous procedures in 2. Younger age and palliative procedures were univariate risk factors for operative death, but only age was an independent predictor on multivariable analysis. CONCLUSIONS: Most patients coming to surgery presented in childhood and were significantly symptomatic. More than half underwent valve replacement or repair, but a considerable proportion had severe disease necessitating 1(1/2) ventricle repair or palliative procedures. Operative mortality did not differ significantly among repair, replacement, and 1(1/2) ventricle repair but was associated with palliative procedures for severe disease early in life, young age being the only independent predictor of operative death.

Report of the 2005 STS Congenital Heart Surgery Practice and Manpower Survey.

BACKGROUND: Limited information is available concerning the congenital heart surgery workforce in North America. To obtain reliable data, The Society of Thoracic Surgeons (STS) Workforce on Congenital Heart Surgery undertook a subspecialty focused survey. METHODS: Preliminary research of websites and databases revealed a potential target group of 263 congenital heart surgeons, including 248 surgeons at 121 US centers and 15 at eight Canadian sites. Surveys were sent to these, plus any additional individuals who listed an interest in congenital or pediatric heart surgery on CTSNet or STS websites. Responders include active congenital heart surgeons, inactive, or retired surgeons, adult cardiac surgeons, and surgeons in training. Analysis is based exclusively on the responses of 217 active congenital heart surgeons (>80% of target). RESULTS: Average age was 48.3 +/- 8.3 years (range, 33 to 78). Ten were female (5%), 207 male (95%). American Medical School graduates were 170 (79%), with 9.2 +/- 1.6 years of postgraduate training. Eighty-five percent are Thoracic Board certified. Congenital heart surgery training outside the United States or Canada was obtained by 29 (14%). One hundred twenty-eight (59%) do exclusively congenital heart surgery. One third perform fewer than 100 congenital cases per year, one third perform 100 to 199, and one third perform 200 or more. Congenital heart surgeons have been in their current positions for 9.5 +/- 8.2 years. Eleven are in their first year of practice. Mean anticipated years to retirement is 15.7 +/- 7.5 (range, 1 to 34). Three anticipate retirement within 1 year. At the same time, 39 fellows will complete postgraduate training at 28 centers this year, and 19 will seek positions in North America. CONCLUSIONS: These data should help to facilitate rational plans to meet manpower needs, including evolving policies concerning training and certification.

The nomenclature, definition and classification of hypoplastic left heart syndrome.

The hypoplastic left heart syndrome encompasses a spectrum of cardiac malformations that are characterized by significant underdevelopment of the components of the left heart and the aorta, including the left ventricular cavity and mass. At the severe end of the spectrum is found the combination of aortic and mitral atresia, when the left ventricle can be close to non-existent. At the mild end are the patients with hypoplasia of the aortic and mitral valves, but without intrinsic valvar stenosis or atresia, and milder degrees of left ventricular hypoplasia. Although the majority of the patients are suitable only for functionally univentricular repair, a small minority may be candidates for biventricular repair. The nature of the syndrome was a topic for discussion at the second meeting of the International Working Group for Mapping and Coding of Nomenclatures for Paediatric and Congenital Heart Disease, the Nomenclature Working Group, held in Montreal, Canada, over the period January 17 through 19, 2003. Subsequent to these discussions, the Nomenclature Working Group was able to create a bidirectional crossmap between the nomenclature initially produced jointly on behalf of the European Association for Cardio-Thoracic Surgery and the Society of Thoracic Surgeons, and the alternative nomenclature developed on behalf of the Association for European Paediatric Cardiology. This process is a part of the overall efforts of the Nomenclature Working Group to create a comprehensive and all-inclusive international system of nomenclature for paediatric and congenital cardiac disease, the International Paediatric and Congenital Cardiac Code. In this review, we discuss the evolution of nomenclature and surgical treatment for the spectrum of lesions making up the hypoplastic left heart syndrome and its related malformations. We also present the crossmap of the associated terms for diagnoses and procedures, as recently completed by the Nomenclature Working Group.

Minimally invasive repair of pectus excavatum in adult patients.

Since 1996, the technique for minimally invasive repair of pectus excavatum (MIRPE) has gained increasing acceptance among pediatric patients. However, the feasibility of the operation and outcomes have not yet been evaluated in adult patients. This study was a retrospective analysis of the author's experience combined with a survey of members of the American Pediatric Surgical Association in treating adult patients with MIRPE. Thirty adults (age range, 18-32 years; mean, 23 years; 75% men) with severe pectus excavatum (chest index > 3.2) were treated with MIRPE. The main indication for surgery was cosmetic (80%). One 32-year-old female patient underwent simultaneous MIRPE and breast augmentation. In 60 per cent of cases, the operative time was 1 to 2 hours. Thoracic epidural was successfully used for postoperative pain management in 90 per cent of patients. Two pectus bars were necessary in 16 per cent of cases, and bilateral stabilizers were used in 53 per cent of patients. Complications included seroma (10%), bar displacement (6%), pneumothorax requiring tube thoracostomy (6%), superficial wound infection (3%), and stabilizer bar fracture (3%). Two patients required conversion to modified Ravitch repair. Patient satisfaction was rated as excellent (50%), good (36%), and fair (14%). Less than 50 per cent of patients achieved 100 per cent correction of their deformity. MIRPE can be used safely for repair of pectus excavatum in adult patients. The complication rate appears to be similar to previously reported series of pediatric patients. Although adult patients may have residual asymmetry of the chest postrepair, overall satisfaction with the repair was very good or excellent in 86 per cent of patients.

Initial experience with a bicuspid polytetrafluoroethylene pulmonary valve in 41 children and adults: a new option for right ventricular outflow tract reconstruction.

BACKGROUND: As the population of children with repaired congenital heart disease ages, an increasing number of patients will benefit from pulmonary valve insertion. We report our initial experience in 41 consecutive patients treated with placement of a surgically created polytetrafluoroethylene bicuspid pulmonary valve. METHODS: A bicuspid pulmonary valve with orifice size greater than 24 mm is created with polytetrafluoroethylene and sutured into the right ventricular outflow tract. To obviate the need for reoperation in growing children, this technique is limited to older children and adults. Polytetrafluoroethylene bicuspid pulmonary valves were placed in 41 patients (age: range, 5.0 to 64.7 years, median = 15.7 years; weight: range, 14.2 to 99.0 kilograms, median, 52.0 kg). All patients had pulmonary insufficiency, pulmonary stenosis, or both, after previous intervention for tetralogy of Fallot (27), pulmonary stenosis (11), pulmonary atresia with intact ventricular septum (2), or double outlet right ventricle (1). RESULTS: All patients left the operating theater with transesophageal echocardiography documenting no pulmonic stenosis and zero to trace pulmonic insufficiency. Median hospital length of stay was 5 days (range, 3 to 15 days; mean, 5.8 days). Follow-up including echocardiography ranged from 0.2 to 3.1 year (median follow-up, 1.5 years) and revealed significant improvement in New York Heart Association Classification, pulmonary insufficiency, and right ventricular end diastolic dimension. CONCLUSIONS: Polytetrafluoroethylene bicuspid pulmonary valve reconstruction of the right ventricular outflow tract is a safe, effective, and durable technique for the short term. Appropriate oversizing minimizes outflow tract obstruction while maximizing competence. Long-term follow-up is necessary to determine the true value of this technique.

Aortic translocation in the management of transposition of the great arteries with ventricular septal defect and pulmonary stenosis: results and follow-up.

BACKGROUND: The surgical management of patients with transposition of the great arteries, ventricular septal defect, and pulmonary stenosis remains a challenge. The Rastelli operation is the preferred surgical procedure, but its long-term results are not optimal. The objective in this retrospective study was to review our experience using aortic translocation and biventricular outflow tract reconstruction as an alternative surgical procedure for the management of these patients. METHODS: Since January 1996, 12 patients have undergone aortic translocation and biventricular outflow tract reconstruction for the management of transposition of the great arteries, ventricular septal defect, and pulmonary stenosis at our institution. All patients had ventriculoarterial discordance; 9 had atrioventricular concordance and 3 atrioventricular discordance. Associated lesions included a straddling atrioventricular valve in 3 patients. An inlet ventricular septal defect was present in 4 patients. The median age at operation was 2 years. Eight patients had previous palliative procedures. The surgical technique used was a modification of the Nikaidoh procedure. The 3 patients with atrioventricular discordance required a Senning procedure. RESULTS: There was one hospital death (8.3%) as a result of a massive cerebrovascular accident. The median intensive care unit and hospital stays were 15 and 18 days, respectively. At a median follow-up of 33 months, all patients are alive. Four late reoperations occurred in 3 patients, including two reoperations for conduit obstruction. CONCLUSIONS: Aortic translocation and biventricular outflow tract reconstruction is a valuable surgical option for the surgical management of patients with transposition of the great arteries, ventricular septal defect, and pulmonary stenosis, especially in the presence of "inadequate anatomy" for a Rastelli repair.

Current status of the European Association for Cardio-Thoracic Surgery and the Society of Thoracic Surgeons Congenital Heart Surgery Database.

BACKGROUND: After utilizing separate congenital databases in the early 1990s, the Society of Thoracic Surgeons (STS) and the European Association for Cardio-Thoracic Surgery (EACTS) collaborated on several joint database initiatives. METHODS: In 1998, the joint EACTS-STS International Congenital Heart Surgery Nomenclature and Database Project Committee was created and a common nomenclature and common core minimum database dataset were adopted and published by the STS and the EACTS. In 1999, the joint EACTS-STS Aristotle Committee was created and the Aristotle Score was adopted and published as a method to provide complexity adjustment for congenital heart surgery. Collaborative efforts involving the EACTS and STS are underway to develop mechanisms to verify data completeness and accuracy. RESULTS: Since 1998, this nomenclature, database, and methodology of complexity adjustment have been used by both the STS and EACTS to analyze outcomes of over 40,000 patients. A huge amount of data have been generated which allow comparison of practice patterns and outcomes analysis between Europe and North America. The aggregate data from the first 5 years of data collection not only make for interesting comparison but also allow examination of regional difference in practice patterns. For example, in the EACTS, out of 4,273 neonates, 885 (20.7%) underwent arterial switch procedures and 297 (6.95%) underwent Norwood stage 1 procedures. In the STS, out of 3,988 neonates, 472 (11.8%) underwent arterial switch procedures and 575 (14.4%) underwent Norwood stage 1 procedures. CONCLUSIONS: This analysis of the EACTS-STS multi-institutional outcomes database confirms that in both Europe and North America, case complexity and mortality is highest among neonates, then infants, and then children. Regional differences in practice patterns are demonstrated, with the overall goal being the continued upgrade in the quality of surgery for congenital heart disease worldwide.

Interrupted aortic arch: surgical decision making.

Interrupted aortic arch (IAA) is defined as the loss of luminal continuity between the ascending and descending aorta. It is associated with a multitude of lesions ranging from isolated ventricular septal defects to complex ones. Although results have improved in the modern era, repair of IAA is associated with a significant mortality and morbidity. In recent years, the move to a one-stage repair has become well established, and the optimal technique for aortic repair seems to be partial direct anastomosis with patch augmentation. Left ventricular outflow tract obstruction (LVOTO) continues to be an important factor affecting survival and re-intervention rates after IAA repair. Great variability exists with regard to definition and diagnosis of LVOTO. To guide the decision for left ventricular outflow tract (LVOT) intervention and which type to use, we propose a simple formula based on the baby's weight. We advocate a conservative approach when the LVOT diameter is greater than the baby's weight + 2 mm and a LVOT bypass procedure (Yasui or Norwood) if the LVOT diameter is less than the baby's weight in millimeters. If the LVOT diameter falls in between, no definitive recommendation can be made, and the surgical approach is based on the surgeon's experience and overall philosophy.

Evaluation of quality of care for congenital heart disease.

There is widespread recognition that surgical outcomes differ by surgeon and institution; however, the definition and measurement of quality in pediatric cardiac surgery is in its infancy. This article discusses the definition of quality, what has been done to define and measure quality of pediatric cardiac surgery, and how to proceed. Descriptions of assessment of quality by evaluating structure, process, and outcome measures; efforts to establish a global congenital heart surgery database; and a comparison of risk-adjusted mortality rates using the Risk Adjustment for Congenital Heart Surgery method are included.

Pediatric cardiac transplantation in children with high panel reactive antibody.

BACKGROUND: Elevated panel reactive antibody (PRA) may be considered a risk factor precluding pediatric orthotopic heart transplantation. We retrospectively reviewed our management strategy and outcome data for children undergoing heart transplantation with high PRA (> 10%). METHODS: Sixty consecutive children (median age = 130.5 days) underwent heart transplantation. Diagnoses included hypoplastic left heart syndrome (HLHS) (30 patients), cardiomyopathy (18 patients), and postoperative complex congenital heart disease (CCHD) (12 patients). Standard induction immunosuppressive therapy included pulse steroids, gamma globulin, and polyclonal rabbit antithymocyte globulin. Initial immunosuppression is a calcinurin inhibitor and an antiproliferative agent. Eight children exhibited elevated PRA (group P). Fifty-two exhibited nonelevated PRA (group N). Immunosuppression was modified in group P as follows: preoperative intravenous immunoglobulin G (IVIG) and/or cyclophosphamide or mycophenolate mofetil and preoperative and postoperative exchange transfusions or plasmapheresis. In group P, cyclophosphamide was the initial antiproliferative agent. RESULTS: Group P = 4 HLHS patients (all status post [s/p] prior cardiac surgery) and 4 postoperative CCHD patients. Group N = 26 HLHS patients (4 patients s/p prior cardiac surgery), 18 cardiomyopathy patients, and 8 postoperative CCHD patients. Group P patients were older and weighed more than group N patients. Waiting time for donor heart, cardiac ischemic time, and length of hospital stay were similar in both groups. Thirty-day mortality for group P was 25% and for group N it was 7.9% (p = 0.178). Overall mortality for group P was 50% and for group N it was 15.4% (p = 0.043). CONCLUSIONS: Although heart transplantation can offer children with end-stage heart failure and elevated PRA their only chance of survival, these patients remain high risk despite aggressive immunosuppression.
