Hybrid Interventions in Congenital Heart Disease: A Review of Current Practice and Rationale for Use. Ann Thorac Surg 2024:S0003-4975(24)00184-X. [PMID: 38462049 DOI: 10.1016/j.athoracsur.2024.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 02/14/2024] [Accepted: 03/04/2024] [Indexed: 03/12/2024]
Abstract
BACKGROUND Hybrid interventions have become a common option in the management for a variety of patients with congenital heart disease. In this review, we discuss the data that have driven decision making about hybrid interventions to date. METHODS The existing literature on various hybrid approaches was reviewed and summarized. In addition, the key tenants to creating a successful hybrid program within a congenital heart center are elucidated. RESULTS Hybrid strategies for single-ventricle patients, pulmonary atresia with intact ventricular septum, branch pulmonary artery stenosis, and muscular ventricular septal defect closure have important benefits and limitations compared with traditional approaches. CONCLUSION A growing body of evidence supports the use of hybrid interventions in congenital heart disease. But important questions remain regarding improved survival and other long-term outcomes, such as neurocognition, that might impact widespread adoption as a primary treatment strategy.

Hypoplastic Left Heart Syndrome with Mitral Stenosis and Aortic Atresia - Echocardiographic Findings and Early Outcomes. J Am Soc Echocardiogr 2024:S0894-7317(24)00085-3. [PMID: 38432347 DOI: 10.1016/j.echo.2024.02.008] [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: 08/28/2023] [Revised: 02/13/2024] [Accepted: 02/13/2024] [Indexed: 03/05/2024]
Abstract
BACKGROUND Mitral stenosis/aortic atresia (MS/AA) has been reported as a high-risk variant of hypoplastic left heart syndrome (HLHS), potentially related to ventriculocoronary connections (VCCs) or endocardial fibroelastosis (EFE) and myocardial hypoperfusion. We aimed to identify echocardiographic and clinical factors associated with early death or transplant in this group. METHODS Patients with HLHS MS/AA treated at our center between 2000 and 2020 were included. Pre stage I palliation echocardiograms were reviewed. Certain imaging factors, such as determination of VCC, EFE, and measurement of tricuspid annular plane systolic excursion (TAPSE) were measures from retrospective review of pre-operative images; others were derived from clinical reports. Groups were compared according to primary outcome of death or transplant prior to stage II palliation (S2P). RESULTS Of 141 patients included, 39 (27.7%) experienced primary outcome. VCCs were identified in 103 (73.0%) patients and EFE in 95 (67.4%) patients. Among imaging variables, smaller ascending aorta size (median 2.2 [IQR 1.7-2.8] vs 2.6 [2.2-3.4] mm, p=0.01) was associated with primary outcome. There was similar frequency of VCC (74.4 vs 72.5%, p=0.83), EFE (59.0 vs 72.5%, p=0.19), moderate or greater tricuspid regurgitation (5.1 vs 5.9%, p=1.00), and similar right ventricular systolic function (indexed TAPSE 32.5 ± 7.3 vs 31.4 ± 7.2 mm/m2, p=0.47) in the primary outcome group compared to other patients. Clinical factors associated with primary outcome included lower birth weight (mean 2.8 ± SD 0.8 vs 3.3 ± 0.5 kg, p=0.0003), gestational age <37 weeks (31.6 vs 4.9%, p<.0001), longer cardiopulmonary bypass time (median 112 [IQR 93-162] vs 82 [71-119] minutes, p=0.001), longer intensive care unit length of stay (median 19 [IQR 10-30] vs 10 [7-15] days, p=0.001), and extracorporeal membrane oxygenation following stage I palliation (43.6 vs 8.8%, p<.0001). Presence of VCCs and EFE were not associated with death or transplant after controlling for birth weight and era of S1P. CONCLUSIONS In one of the largest reported single-center cohorts of HLHS MS/AA, there were few pre-stage I palliation imaging characteristics associated with primary outcome. Imaging findings evaluated in this study, including the presence of VCC and/or EFE as determined using highly sensitive echocardiogram criteria, should not preclude intervention, although impact on long-term outcomes requires further evaluation.

Association Between Past and Present Operative Mortality in Congenital Heart Surgery. Ann Thorac Surg 2024:S0003-4975(24)00122-X. [PMID: 38401767 DOI: 10.1016/j.athoracsur.2024.02.018] [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: 08/31/2023] [Revised: 01/18/2024] [Accepted: 02/11/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND Mortality following congenital heart surgery is an important metric across benchmarking, quality, and reporting initiatives. All rely on estimates from prior years, and it is unclear how well these reflect current outcomes. METHODS STS Congenital Database index operations (2014-2019) were included. Adjusted operative mortality in "past" 4- and 1-year intervals vs. the most recent year ("present") was evaluated using Bayesian hierarchical logistic regression with results presented as odds ratios (95% credible interval). RESULTS Among 115,699 operations (106 hospitals), overall present observed mortality was 2.5%. Regression to the mean was evident and individual hospital's present vs. past adjusted mortality were only weakly correlated (-0.11 vs. past 1-year, 0.22 vs. past 4-year data). There was a significant relationship between past and present mortality only for the group of hospitals in the highest mortality quartile, most prominent for past 4-year data [adjusted odds ratio vs. lowest mortality quartile 2.04 (1.44-2.80)]. The proportion of present hospital mortality variation explained by past mortality quartile was 52% (20%-90%) using past 4-year and only 27% (92%-83%) using past 1-year data. Overall 66% of hospitals changed mortality quartiles from past to present (30% by ≥2 quartiles). CONCLUSIONS Past mortality relates to present primarily for groups of hospitals at the extremes, with past 4-year more informative than past 1-year data. For individual hospitals, past may differ from present, regression to the mean is common, and many change quartiles. Past mortality should be used thoughtfully and not as the sole factor informing present decision making.

Abstract
BACKGROUND The use of transcatheter aortic valve replacement for severe aortic stenosis in low-risk patients necessitates an evaluation of contemporary long-term, real-world outcomes of similar patients undergoing surgical aortic valve replacement (SAVR) in a national cohort. METHODS All patients undergoing primary, isolated SAVR in The Society of Thoracic Surgeons (STS) database between 2011 and 2019 were examined. The study population of 42,586 adhered to the inclusion/exclusion criteria of the Placement of Aortic Transcatheter Valves (PARTNER) 3 and Evolut Low Risk randomized trials. Patients were further stratified by STS predicted risk of mortality (PROM), age, and left ventricular ejection fraction. The primary end-point was all-cause National Death Index mortality. Unadjusted survival to 8 years was estimated using the Kaplan-Meier method. RESULTS Mean age was 74.3 ± 5.7 years and mean STS PROM was 1.9% ± 0.8%. The overall Kaplan-Meier time to event analysis for all-cause mortality at 1, 3, 5, and 8 years was 2.6%, 4.5%, 7.1%, and 12.4%, respectively. In subset analyses, survival was significantly better for (1) lower STS PROM (P < .001), (2) younger vs older age (P < .001), and (3) higher vs lower left ventricular ejection fraction (P < .001). When STS PROM was below 1% or the patient age was below age 75 years, the 8-year survival after SAVR was 95%. CONCLUSIONS The results of this national study confirm that long-term survival after SAVR remains excellent, at 92.9% at 5 years. These contemporary longitudinal data serve to aid in the balanced interpretation of current and future trials comparing SAVR and transcatheter aortic valve replacement and may assist in the clinical decision-making process for patients of lower surgical risk.

Abstract
Care and outcomes for the more than 40,000 patients undergoing pediatric and congenital heart surgery in the United States annually are known to vary widely. While consensus recommendations have been published across numerous fields as one mechanism to promote a high level of care delivery across centers, it has been more than two decades since the last pediatric heart surgery recommendations were published in the United States. More recent guidance is lacking, and collaborative efforts involving the many disciplines engaged in caring for these children have not been undertaken to date. The present initiative brings together professional societies spanning numerous care domains and congenital cardiac surgeons, pediatric cardiologists, nursing, and other healthcare professionals from diverse programs around the country to develop consensus recommendations for United States centers. The focus of this initial work is on pediatric heart surgery, and it is recommended that future efforts focus in detail on the adult congenital population. We describe the background, rationale, and methodology related to this collaborative effort, and recommendations put forth for Essential Care Centers (essential services necessary for any program), and Comprehensive Care Centers (services to optimize comprehensive and high-complexity care), encompassing structure, process, and outcome metrics across 14 domains.

Contemporary Relationship Between Hospital Volume and Outcomes in Congenital Heart Surgery. Ann Thorac Surg 2023; 116:1233-1239.

Abstract
BACKGROUND Studies examining the volume-outcome relationship in congenital heart surgery (CHS) are more than a decade old. Since then, mortality has declined, and case-mix adjustment has evolved. We determined the current relationship between hospital CHS volume and outcomes. METHODS Patients aged ≤18 years undergoing index operations in The Society of Thoracic Surgeons-Congenital Heart Surgery Database (2017-2020) were included. Associations between annual hospital volume and case-mix-adjusted operative mortality, major complications, failure to rescue (FTR), and postoperative length of stay (PLOS) were assessed using Bayesian hierarchical models, overall, by The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) category, and for the Norwood procedure. RESULTS Across 101 centers (76,714 index operations), median annual volume was 144 operations/y. Operative mortality was 2.7%. Lower-volume hospitals had higher mortality, with an apparent transition zone at ∼190 operations/y (95% credible interval [CrI], 115-450 operations/y), below which a sustained uptick in the estimated odds of death occurred. Odds of death compared with a 450 operations/y reference were 50 operations/y (odds ratio [OR], 1.84; 95% CrI, 1.41-2.37), 100 operations/y (OR, 1.37; 95% CrI, 1.08-1.71), 200 operations/y (OR, 0.92; 95% CrI, 0.1-1.18), 300 operations/y (OR, 0.89; 95% CrI, 0.76-1.04). The volume-outcome effect was more apparent for STAT 4 to 5 than STAT 1 to 3 operations. In the overall cohort, PLOS and complications were similar across hospital volumes, whereas FTR rates were higher at lower-volume hospitals. Lower-volume hospitals had worse outcomes after the Norwood procedure, most notably mortality and FTR. CONCLUSIONS Hospital volume is associated with mortality and FTR after CHS. The relationship is strongest for high-risk operations. These data can inform ongoing initiatives to improve CHS care.

Long-Term Impact of Anatomic Subtype in Hypoplastic Left Heart Syndrome after Fontan Completion. J Thorac Cardiovasc Surg 2023:S0022-5223(23)01075-9.

Abstract
BACKGROUND Aortic atresia (AA)/mitral stenosis (MS) is a well-known risk factor for survival after Norwood; however, the effect of anatomical subtypes in those who survive surgical palliation is unknown. METHODS We performed a retrospective single-center study of patients with classic HLHS who underwent Fontan at our center between 8/1989 and 7/2017. Clinical outcomes, as well as ventricular and atrioventricular valve (AVV) function, were determined for each patient, and the effects of HLHS subtype were estimated using multivariable statistical analyses. RESULTS We included 418 HLHS patients (AA/mitral atresia [MA] 153, AA/MS 100, aortic stenosis [AS]/MS 154, and AS/MA 11). The median follow-up period was 8.6 (IQR 2.9-15.8) years. Overall transplant-free survival, cumulative incidence of AVV failure, and ventricular failure, which were defined by ≥ moderate dysfunction or the necessity of surgical interventions, were 70.1, 35.9, and 17.9% at 20 years, respectively. Of the three major subtypes, AA/MS was associated with lower survival rate (AA/MA 74.6 vs AS/MS 79.1 vs AA/MS 56.1 % at 17 years, P=0.04). The sub-analysis between AA/MA and AA/MS revealed AA/MS tended to have a higher rate of ventricular failure without a significant difference of AVV failure (AA/MA 11.2% vs. AA/MS 26.2% at 17 years, P=0.053). CONCLUSIONS The survival risk of the anatomic subtype AA/MS persisted long-term after Fontan completion and was likely due to a higher rate of single ventricle rather than AVV failure. These findings suggest that the abnormal pressure overload condition of the hypoplastic left ventricle created by AA/MS has a detrimental effect on single right ventricle function.

Abstract
BACKGROUND Hybrid palliation (bilateral pulmonary artery banding with or without ductal stenting) is an initial management strategy for infants with critical left heart obstruction and serves as palliation until subsequent operations are pursued. OBJECTIVES This study sought to determine patient characteristics and factors associated with subsequent outcomes for infants who underwent hybrid palliation. METHODS From 2005 to 2019, 214 of 1,236 prospectively enrolled infants within the Congenital Heart Surgeons' Society's critical left heart obstruction cohort underwent hybrid palliation across 24 institutions. Multivariable hazard modeling with competing risk methodology was performed to determine risk and factors associated with outcomes of biventricular repair, Fontan procedure, transplantation, or death. RESULTS Preoperative comorbidities (eg, prematurity, low birth weight, genetic syndrome) were identified in 70% of infants (150 of 214). Median follow-up was 7 years, ranging up to 17 years. Overall 12-year survival was 55%. At 5 years after hybrid palliation, 9% had biventricular repair, 36% had Fontan procedure, 12% had transplantation, 35% died without surgical endpoints, and 8% were alive without an endpoint. Factors associated with transplantation were absence of ductal stent, older age, absent interatrial communication, smaller aortic root size, larger tricuspid valve area z-score, and larger left ventricular volume. Factors associated with death were low birth weight, concomitant genetic syndrome, cardiopulmonary bypass use during hybrid palliation, moderate to severe tricuspid valve regurgitation, and smaller ascending aortic size. CONCLUSIONS Mortality remains high after hybrid palliation for infants with critical left heart obstruction. Nonetheless, hybrid palliation may facilitate biventricular repair for some infants and for others may serve as stabilization for intended functional univentricular palliation or primary transplantation.

Abstract
OBJECTIVE Neonates with tetralogy of Fallot and pulmonary atresia (TOF/PA) but no major aorta-pulmonary collaterals are dependent on the arterial duct for pulmonary blood flow and require early intervention, either by primary (PR) or staged repair (SR) with initial palliation (IP) followed by complete repair (CR). The optimal approach has not been established. METHODS Neonates with TOF/PA who underwent PR or SR were retrospectively reviewed from the Congenital Cardiac Research Collaborative. Outcomes were compared between PR and SR (IP + CR) strategies. Propensity scoring was used to adjust for baseline differences. The primary outcome was mortality. Secondary outcomes included complications, length of stay, cardiopulmonary bypass and anesthesia times, reintervention (RI), and pulmonary artery (PA) growth. RESULTS Of 282 neonates, 106 underwent PR and 176 underwent SR (IP: 144 surgical, 32 transcatheter). Patients who underwent SR were more likely to have DiGeorge syndrome and greater rates of mechanical ventilation before the initial intervention. Mortality was not significantly different. Duration of mechanical ventilation, inotrope use, and complication rates were similar. Cumulative length of stay, cardiopulmonary bypass, and anesthesia times favored PR (P ≤ .001). Early RI was more common in patients who underwent SR (rate ratio, 1.42; P = .003) but was similar after CR (P = .837). Conduit size at the time of CR was larger with SR. Right PA growth was greater with PR. CONCLUSIONS In neonates with TOF/PA, SR is more common in greater-risk patients. Accounting for this, SR and PR strategies have similar mortality. Perioperative morbidities, RI, and right PA growth generally favor PR, whereas SR allows for larger initial conduit implantation.

Abstract
BACKGROUND Neonates with symptomatic tetralogy of Fallot (sTOF) with hypoplastic pulmonary arteries (hPA) are considered high risk. Data are needed to inform the impact of hPA on outcomes, and the ideal management strategy. OBJECTIVES The objectives of this study were to quantify the impact of hPA on outcomes in neonates with sTOF and measure the impact of strategy on pulmonary artery (PA) growth in this population. METHODS Neonates with sTOF from 2005 to 2017 were reviewed from the Congenital Cardiac Research Collaborative. Criteria for hPA included a unilateral PA z score <-2.0 and contralateral PA z score <0. Primary outcome was mortality. Secondary outcomes included reintervention and PA growth. RESULTS We included 542 neonates with sTOF, including 188 (35%) with hPA and 354 (65%) with normal PA, with median follow-up of 4.1 years. Median right and left hPA z scores were -2.19 (25th-75th percentile: -2.55 to -1.94) and -2.23 (25th-75th percentile: -2.64 to -1.91), respectively. Staged repair (vs primary TOF repair) was less common in the hPA cohort (36 vs 44%; P = 0.07). Survival was similar between groups (unadjusted P = 0.16; adjusted P = 0.25). Reintervention was more common in the hPA group (HR: 1.28; 95% CI: 1.01-1.63; P = 0.044); there was no difference after definitive repair (HR: 1.21; 95% CI: 0.93-1.58; P = 0.16). PA growth at 1 year was greater in the hPA cohort, particularly for the right PA (P < 0.001). CONCLUSIONS Despite perception, the presence of hPA in neonates with sTOF conferred no increase in overall hazard of mortality or reintervention after definitive repair. PA growth was superior in the hPA cohort. These findings suggest that the presence of hPA does not adversely impact outcomes in sTOF.

Representation of Women and Minority Faculty and Fellows in Academic Pediatric Cardiology Training Programs. J Am Coll Cardiol 2023; 81:1181-1188. [PMID: 36948735 DOI: 10.1016/j.jacc.2023.01.022] [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: 10/24/2022] [Revised: 01/13/2023] [Accepted: 01/17/2023] [Indexed: 03/24/2023]
Abstract
BACKGROUND Studies have shown that diverse care teams optimize patient outcomes. Describing the current representation of women and minorities has been a critical step in improving diversity across several fields. OBJECTIVES To address the lack of data specific to pediatric cardiology, the authors conducted a national survey. METHODS U.S. academic pediatric cardiology programs with fellowship training programs were surveyed. Division directors were invited (July 2021 to September 2021) to complete an e-survey of program composition. Underrepresented minorities in medicine (URMM) were characterized using standard definitions. Descriptive analyses at the hospital, faculty, and fellow level were performed. RESULTS Altogether, 52 of 61 programs (85%) completed the survey, representing 1,570 total faculty and 438 fellows, with a wide range in program size (7-109 faculty, 1-32 fellows). Although women comprise approximately 60% of faculty in pediatrics overall, they made up 55% of fellows and 45% of faculty in pediatric cardiology. Representation of women in leadership roles was notably less, including 39% of clinical subspecialty directors, 25% of endowed chairs, and 16% of division directors. URMM comprise approximately 35% of the U.S. population; however, they made up only 14% of pediatric cardiology fellows and 10% of faculty, with very few in leadership roles. CONCLUSIONS These national data suggest a "leaky pipeline" for women in pediatric cardiology and very limited presence of URRM overall. Our findings can inform efforts to elucidate underlying mechanisms for persistent disparity and reduce barriers to improving diversity in the field.

Congenital Heart Surgery Training Experiences and Perceptions Among Cardiothoracic Surgery Residents. Semin Thorac Cardiovasc Surg 2023; 35:148-155. [PMID: 35278667 DOI: 10.1053/j.semtcvs.2022.03.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 03/03/2022] [Indexed: 11/11/2022]
Abstract
Interest and core training in congenital heart surgery (CHS) has not been characterized among current cardiothoracic surgical trainees. This study aimed to evaluate perceptions, interest, exposure, and experience among current trainees. A 22 question survey was distributed to all cardiothoracic surgical trainees in ACGME-accredited thoracic surgery residencies. Questions included demographics, exposure to CHS during, perceptions of, participation in and quality assessment of CHS training. There were 106 responses (20.1% response rate) of which 31 (29.0%) were female and 87 (81.3%) were cardiothoracic track. While 69 (64.5%) reported having an interest in CHS at some point during training, only 24 (22.4%) were actively pursuing CHS. All but 7 (6.5%) residents reported having easy access to congenital mentorship, with 35 (32.7%) actively participating in CHS research. Three months was the median duration of congenital rotations. Residents reported less operative participation on CHS compared to adult cardiac surgery. Several residents noted the need for earlier exposure and increased technical/operative experience as areas in need of improvement. The most cited primary influences to pursue CHS included: mentorship, breadth of pathology, and technical nature of the specialty. Lack of consistent job availability and length of additional training were reported as negative influences. Cardiothoracic residents report adequate exposure to obtain case requirements and knowledge for board examinations in CHS but highly variable operative involvement. Mentorship and early exposure remain important for those interested in CHS, while additional training time and limited job availability remain hurdles to CHS.

Impact of Management Strategy on Feeding and Somatic Growth in Neonates with Symptomatic Tetralogy of Fallot: Results from the Congenital Cardiac Research Collaborative. J Pediatr 2022; 250:22-28.e4. [PMID: 35772511 DOI: 10.1016/j.jpeds.2022.06.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 06/10/2022] [Accepted: 06/22/2022] [Indexed: 12/19/2022]
Abstract
OBJECTIVE To evaluate early growth following primary or staged repair of neonatal symptomatic tetralogy of Fallot (sTOF). STUDY DESIGN We performed a retrospective, multicenter cohort study of consecutive infants with sTOF who underwent initial intervention at age ≤30 days, from 2005 to 2017. Management strategies were either primary repair or staged repair (ie, initial palliation followed by complete repair). The primary outcome was change in weight-for-age z-score (ΔWAZ) from the initial intervention to age 6 ± 2 months. Secondary outcomes included method and mode of feeding, feeding-related medications, and feeding-related readmissions. Propensity score adjustment was used to account for baseline differences between groups. A secondary analysis was performed comparing patients stratified by the presence of adequate growth (6-month ΔWAZ > -0.5) or inadequate growth (6-month ΔWAZ ≤ -0.5), independent of treatment strategy. RESULTS The study cohort included 143 primary repair subjects and 240 staged repair subjects. Prematurity was more common in the staged repair group. After adjustment, median ΔWAZ did not differ between treatment groups over the first 6 months of life (primary: -0.43 [IQR, -1.17 to 0.50]; staged: -0.31 [IQR, -1.31 to 0.71]; P = .55). For the entire cohort, ΔWAZ was negative (-0.36; IQR, -1.21 to 0.63). There were no between-group differences in the secondary outcomes. Secondary analysis revealed that the subjects with adequate growth were more likely to be orally fed at initial hospital discharge (P = .04). CONCLUSIONS In neonates with sTOF, growth trajectory over the first 6 months of life was substandard, irrespective of treatment strategy. Those patients with adequate growth were more likely to be discharged from the index procedure on oral feeds.

Abstract
Neonates with symptomatic tetralogy of Fallot (sTOF) may undergo palliations with varying physiology, namely systemic to pulmonary artery connections (SPC) or right ventricular outflow tract interventions (RVOTI). A comparison of palliative strategies based on the physiology created is lacking. Consecutive sTOF neonates undergoing SPC or RVOTI from 2005-2017 were reviewed from the Congenital Cardiac Research Collaborative. The primary outcome was survival with successful complete repair (CR) by 18 months. A variety of secondary outcomes were assessed including overall survival, hospitalization-related comorbidities, and interstage reinterventions. Propensity score adjustment was utilized to compare treatment strategies. The cohort included 252 SPC (surgical shunt = 226, ductus arteriosus stent = 26) and 68 RVOTI (balloon pulmonary valvuloplasty = 48, RVOT stent = 11, RVOT patch = 9) patients. Genetic syndrome (29 [42.6%] v 75 [29.8%], p = 0.04), weight < 2.5 kg (28 [41.2%] v 68 [27.0%], p = 0.023), bilateral pulmonary artery Z-score < - 2 (19 [28.0%] v 36 [14.3%], p = 0.008), and pre-intervention antegrade flow (48 [70.6%] v 104 [41.3%], p < 0.001) were more common in RVOTI. Significant center differences were noted (p < 0.001). Adjusted survival to CR by 18 months (HR = 0.87, 95% CI = 0.63-1.21, p = 0.41) and overall survival (HR = 2.08, 95% CI = 0.93-4.65, p = 0.074) were similar. RVOTI had increased interstage reintervention (HR = 2.15, 95% CI = 1.36-3.99, p = 0.001). Total anesthesia (243 [213, 277] v 328 [308, 351] minutes, p < 0.001) and cardiopulmonary bypass times (117 [103, 132] v 151 [143, 160] minutes, p < 0.001) favored RVOTI. In this multicenter comparison of physiologic palliation strategies for sTOF, survival to successful CR and overall survival were similar; however, reintervention burden was significantly higher in RVOTI.

Abstract
OBJECTIVE There are limited data regarding the impact of gender within congenital heart surgery. Our aim was to assess gender-related experiences by surgeons in this field. METHODS A cross-sectional survey was emailed to practicing congenital heart surgeons to ascertain the perception of gender in 5 domains: training, professional career, clinical practice, personal life, and career outlook. RESULTS The survey response rate was 94% (17/18) for women and 44% (112/257) for men. More than half of women (53%) were discouraged from pursuing congenital heart surgery (P < .001) and reported a negative impact of gender in attaining their first congenital heart surgery job (P < .001) compared with men. Despite similar demographics, women reported lower starting annual salaries ($150K-$250K vs $250K-$400K), lower current annual salaries ($500K-$750K vs $750K-$1M), lower academic ranks (clinical instructor 6% vs 4% [P = .045], assistant professor 35% vs 19% [P = .19], associate professor 41% vs 25% [P = .24], and professor 6% vs 41% [P = .005]) along with lower annual salaries at the associate professor ($500K-$750K vs $1M-$1.25M) and professor levels ($1M-$1.25M vs >$1.5M) compared with men. Sexual harassment was experienced more frequently by women both in training (65% vs 6%, P < .001) and in practice (65% and 4%, P < .001). CONCLUSIONS This survey highlights many areas of gender-related differences: discouragement due to gender to pursue congenital heart surgery, sexual harassment in training and practice, salary and academic rank differentials, negative gender perception at work, and lower career satisfaction for women. Despite various differences between both genders, the majority in each group would choose to enter this profession again as well as encourage others to do so.

Abstract
OBJECTIVES During congenital heart surgery, the pulmonary valve and root may be placed into the systemic position, yielding a "neoaortic" valve. With the stress of systemic pressure, the pulmonary roots can dilate, creating aneurysms and/or neoaortic insufficiency (neoAI). This report analyzes the early outcomes of patients undergoing neoaortic valve repair incorporating geometric ring annuloplasty. METHODS Twenty-one patients underwent intended repair at six centers and formed the study cohort. Thirteen had previous Ross procedures, five had arterial switch operations, and three Fontan physiology. Average age was 21.7 ± 12.8 years (mean ± SD), 80% were male, and 11 (55%) had symptomatic heart failure. Preoperative neoAI Grade was 3.1 ± 1.1, and annular diameter was 30.7 ± 6.5 mm. RESULTS Valve repair was accomplished in 20/21, using geometric annuloplasty rings and leaflet plication (n = 13) and/or nodular release (n = 7). Fourteen had neoaortic aneurysm replacement (13 with root remodeling). Two underwent bicuspid valve repair. Six had pulmonary conduit changes, one insertion of an artificial Nodulus Arantius, and one resection of a subaortic membrane. Ring size averaged 21.9 ± 2.3 mm, and aortic clamp time was 171 ± 54 minutes. No operative mortality or major morbidity occurred, and postoperative hospitalization was 4.3 ± 1.4 days. At discharge, neoAI grade was 0.2 ± 0.4 (P < .0001), and valve mean gradient was ≤20 mm Hg. At average 18.0 ± 9.1 months of follow-up, all patients were asymptomatic with stable valve function. CONCLUSIONS Neoaortic aneurysms and neoAI are occasionally seen late following Ross, arterial switch, or Fontan procedures. Neoaortic valve repair using geometric ring annuloplasty, leaflet reconstruction, and root remodeling provides a patient-specific approach with favorable early outcomes.

Comparative Costs of Management Strategies for Neonates With Symptomatic Tetralogy of Fallot. J Am Coll Cardiol 2022; 79:1170-1180. [PMID: 35331412 DOI: 10.1016/j.jacc.2021.12.036] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 11/22/2021] [Accepted: 12/23/2021] [Indexed: 12/17/2022]
Abstract
BACKGROUND Recent data have demonstrated that overall mortality and adverse events are not significantly different for primary repair (PR) and staged repair (SR) approaches to management of neonates with symptomatic tetralogy of Fallot (sTOF). Cost data can be used to compare the relative value (cost for similar outcomes) of these approaches and are a potentially more sensitive measure of morbidity. OBJECTIVES This study sought to compare the economic costs associated with PR and SR in neonates with sTOF. METHODS Data from a multicenter retrospective cohort study of neonates with sTOF were merged with administrative data to compare total costs and cost per day alive over the first 18 months of life in a propensity score-adjusted analysis. A secondary analysis evaluated differences in department-level costs. RESULTS In total, 324 subjects from 6 centers from January 2011 to November 2017 were studied (40% PR). The 18-month cumulative mortality (P = 0.18), procedural complications (P = 0.10), hospital complications (P = 0.94), and reinterventions (P = 0.22) did not differ between PR and SR. Total 18-month costs for PR (median $179,494 [IQR: $121,760-$310,721]) were less than for SR (median: $222,799 [IQR: $167,581-$327,113]) (P < 0.001). Cost per day alive (P = 0.005) and department-level costs were also all lower for PR. In propensity score-adjusted analyses, PR was associated with lower total cost (cost ratio: 0.73; P < 0.001) and lower department-level costs. CONCLUSIONS In this multicenter study of neonates with sTOF, PR was associated with lower costs. Given similar overall mortality between treatment strategies, this finding suggests that PR provides superior value.

Abstract
OBJECTIVE Gender disparity in cardiothoracic surgery, but not specifically in congenital heart surgery, has been a growing focus. The aim of this study was to describe the experiences related to gender for women in this field. METHODS This cross-sectional survey was designed to assess gender perception in 5 domains: training, professional career, clinical practice, personal life, and career outlook. Inclusion criteria were women who trained and are practicing congenital heart surgery in the United States. RESULTS Eighteen women were identified with a survey response rate of 94% (17/18). The majority of respondents were aged more than 40 years (94%) and White (69%), chose their career in congenital heart surgery during residency (77%), and completed more than 10 years of postgraduate education (56%). More than half were discouraged from congenital heart surgery because of their gender and reported its negative impact on their ability to obtain their first job. The need to "outperform" their male colleagues was nearly universal (94%), and gender pay disparity was reported by 81%. The majority (65%) reported sexual harassment both during surgical training and as staff surgeons. CONCLUSIONS This survey highlights many areas (discouragement due to gender, sexual harassment, and gender disparities in pay and leadership opportunities) that women may perceive as barriers to a successful career in congenital heart surgery. There is an increasing call to action to mitigate these hurdles for women, both to enter and succeed. It is encouraging that the women surveyed would repeat their career choice and are actively mentoring other women to join this field.

Abstract
PURPOSE Timely and high-quality feedback is important in cardiothoracic (CT) surgery education. Feedback on operative proficiency is an area for improvement in CT surgery programs. Traditional evaluations significantly lag behind operative interactions. We hypothesized that use of the System for Improving and Measuring Procedural Learning (SIMPL) app would improve operative feedback for trainees. METHODS Use of SIMPL was evaluated from December 2018 to January, 2021 within an academic CT surgery training program. Ratings include level of supervision, complexity of the operation, and trainee performance. Completion was limited to 72 h after the operation. Descriptive statistics of the users and ratings are presented. RESULTS Over 28 months, 816 evaluations were completed, and of these, 495 had a rating from both the faculty and trainee. There were 19 trainees representing post-graduate years 1-8 and 19 faculty members who received or submitted at least one evaluation over the study period. The number of evaluations for each trainee ranged from 1 to 166 and from 1 to 81 for each of the faculty. The response rate for faculty ranged from 0% to 100%. "Active help" was the most common type of supervision (50.7% by the faculty, 60.4% from the trainees). CONCLUSIONS Use of SIMPL within a CT surgery training program was feasible and engagement was observed from both trainees and faculty. SIMPL provided trainees with timely, concise feedback on operative performance. Further work will focus on correlating SIMPL ratings with pre-existing assessments of performance.

Kommerell diverticulum: distinctions between arch side, and evaluation of morphology, size, and risk. Ann Thorac Surg 2021; 114:848-856.

Abstract
BACKGROUND Kommerell diverticulum (KD) is a dilated proximal aberrant subclavian artery associated with either right or left aortic arches (RAA-ARSA or LAA-ALSA). Although case series suggest KD may be a liability for vascular complications, the risk, pattern of dilation throughout the lifespan, and differences between arch sides, are not known. METHODS A single-center retrospective review of patients of all ages with KD on cross-sectional imaging. Maximal short axis diameter of KD (KDmax), absolute and indexed to descending aortic (DAo) diameter, was correlated with age. Comparisons were made between arch sides. Patients with vascular complications are described. RESULTS One hundred and four patients with KD were included [68 (65%) RAA-ALSA, 36 (35%) LAA-ARSA; 43 (41%) asymptomatic]. Although KDmax was correlated with age (RAA-ALSA r=0.84 [p<.0001]; LAA-ARSA r=0.51 [p=0.001]), KDmax/DAo was not (RAA-ALSA r=0.14 [p=0.27]; LAA-ARSA r=-0.22 [p=0.21]). RAA-ALSA had larger KDmax/DAo (1.02±0.20 vs 0.89±0.18 mm/mm, p=0.002), more symptoms (75% vs 28%, p <.0001), and younger age (median 9.5 vs 61.7 years, p<.0001). Six patients had vascular complications, age 58-80 years, all with LAA-ARSA and risk factors for acquired aneurysms. CONCLUSIONS In older patients, KDmax/DAo was not larger, arguing against isolated KD dilation with age. Diverticula from RAA-ALSA and LAA-ARSA demonstrate different phenotypes, suggesting different disease processes and likely different risk. The incidence of vascular complication was lower than previous reports, and occurred exclusively in patients with LAA-ARSA and aneurysm risk factors. This suggests conservative management of asymptomatic KD is often reasonable, especially with RAA-ALSA.

Abstract
BACKGROUND For the >40,000 US children undergoing congenital heart surgery annually, the relationship between hospital quality and costs remains unclear. Prior studies report conflicting results and clinical outcomes have continued to improve over time. We examined a large contemporary cohort, aiming to better inform ongoing initiatives seeking to optimize healthcare value in this population. METHODS Clinical information (Society of Thoracic Surgeons Congenital Database) was merged with standardized cost data (Pediatric Health Information Systems) for children undergoing heart surgery from 2010-2015. In-hospital cost variability was analyzed using Bayesian hierarchical models adjusted for case-mix. Quality metrics examined included in-hospital mortality, post-operative complications, length of stay (PLOS), and a composite. RESULTS Overall 32 hospitals (n=45,315 patients) were included. Median adjusted cost/case varied across hospitals from $67,700 to $51,200 in the high vs. low cost tertile (ratio 1.32, 95% credible interval 1.29-1.35), and all quality metrics also varied across hospitals. Across cost tertiles there were no significant differences in the quality metrics examined, with the exception of PLOS. The PLOS findings were driven by high-risk STAT 4-5 cases [adjusted median LOS 16.8 vs. 14.9 days in high vs. low cost tertile (ratio 1.13, 1.05-1.24)], and ICU PLOS. CONCLUSIONS Contemporary congenital heart surgery costs vary across hospitals but were not associated with most quality metrics examined, highlighting that performance in one area does not necessarily convey to others. Cost variability was associated with PLOS, particularly related to ICU PLOS and high-risk cases. Care processes influencing PLOS may provide targets for value-based initiatives in this population.

Comparison of management strategies for neonates with symptomatic tetralogy of Fallot and weight <2.5 kg. J Thorac Cardiovasc Surg 2021; 163:192-207.e3. [PMID: 33726912 DOI: 10.1016/j.jtcvs.2021.01.100] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 01/16/2021] [Accepted: 01/18/2021] [Indexed: 12/21/2022]
Abstract
OBJECTIVE To compare management strategies for neonates <2.5 kg with tetralogy of Fallot and symptomatic cyanosis who either undergo staged repair (SR) (initial palliation followed by later complete repair) or primary repair (PR). METHODS Consecutive neonates with tetralogy of Fallot and symptomatic cyanosis weighing <2.5 kg at initial intervention and between 2005 and 2017 were retrospectively reviewed from the Congenital Cardiac Research Collaborative. Primary outcome was mortality and secondary outcomes included component (eg, initial palliation, complete repair, or primary repair) and cumulative (SR: initial palliation followed by later complete repair) hospital and intensive care unit lengths of stay, durations of ventilation, inotrope use, cardiopulmonary bypass time, procedural complications, and reintervention. Outcomes were compared with propensity score adjustments with PR as the reference group. RESULTS The cohort included 76 SR (initial palliation: 53 surgical and 23 transcatheter) and 44 PR patients. The observed risk of overall mortality was similar between SR and PR groups (15.8% vs 18.2%: P = .735). The adjusted hazard of mortality remained similar between groups overall (hazard ratio, 0.59; 95% confidence interval, 0.26-1.36; P = .214), as well as during short-term (<4 months: hazard ratio, 0.37; 95% confidence interval, 0.13-1.09; P = .071) and midterm (>4 months: hazard ratio, 1.32; 95% confidence interval, 0.30-5.79; P = .717) follow-up. Reintervention in the first 18 months was common in both groups (53.2% vs 48.4%; hazard ratio, 1.69; 95% confidence interval, 0.96-2.28; P = .072). Adjusted procedural complications and neonatal morbidity burden were overall lower in the SR group. Cumulative secondary outcome burdens largely favored the PR group. CONCLUSIONS In this study comparing SR and PR treatment strategies for neonates with tetralogy of Fallot and symptomatic cyanosis and weight <2.5 kg, mortality and reintervention burden was highly independent of treatment strategy. Other potential advantages were observed with each approach.

Relationship of Ventricular Morphology and Atrioventricular Valve Function to Long-Term Outcomes Following Fontan Procedures. J Am Coll Cardiol 2021; 76:419-431. [PMID: 32703513 DOI: 10.1016/j.jacc.2020.05.059] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 05/27/2020] [Accepted: 05/28/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND The influence of ventricular morphology on Fontan outcomes is controversial. OBJECTIVES This study hypothesized that dysfunction of the single right ventricle (RV) and right atrioventricular valve regurgitation (AVVR) increases over time and adversely impacts late outcomes following a Fontan operation. A single-center retrospective study was performed. METHODS From 1985 through 2018, 1,162 patients underwent the Fontan procedure at our center and were included in this study. Transplant and takedown free survival, ventricular, and atrioventricular valve dysfunction after Fontan were analyzed. Death or heart transplantation information was obtained from the National Death Index and the Scientific Registry of Transplant Recipients. RESULTS The follow-up rate was 99%. Morphologic RV was present in 58% of patients. Transplant and takedown free survival were 91%, 75%, and 71% at 10 years, 20 years, and 25 years, respectively. Morphologic RV was an independent risk factor for transplant, takedown free survival (hazard ratio: 2.4; p = 0.008). The AVVR, which preceded ventricular dysfunction in most cases, was associated with the development of ventricular dysfunction after Fontan (odds ratio: 4.3; 95% confidence interval: 2.7 to 6.7; p < 0.001). Furthermore, AVVR and ventricular dysfunction progressed over time after Fontan, especially in the RV (AVVR: p < 0.0001, ventricular dysfunction: p < 0.0001). CONCLUSIONS Morphologic RV is negatively associated with the long-term survival following the Fontan, possibly due to a tendency toward progressive AVVR and deterioration of the single ventricle function. Additional volume overload caused by AVVR may be one of the main factors accelerating the dysfunction of the single RV, implying that early valve intervention may be warranted.

Abstract
BACKGROUND Optimal strategies to improve national congenital heart surgery outcomes and reduce variability across hospitals remain unclear. Many policy and quality improvement efforts have focused primarily on higher-risk patients and mortality alone. Improving our understanding of both morbidity and mortality and current variation across the spectrum of complexity would better inform future efforts. METHODS Hospitals participating in the Society of Thoracic Surgeons Congenital Heart Surgery Database (2014-2017) were included. Case mix-adjusted operative mortality, major complications, and postoperative length of stay were evaluated using Bayesian models. Hospital variation was quantified by the interdecile ratio (IDR, upper versus lower 10%) and 95% credible intervals (CrIs). Stratified analyses were performed by risk group (Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery [STAT] category) and simulations evaluated the potential impact of reductions in variation. RESULTS A total of 102 hospitals (n=84 407) were included, representing ≈85% of US congenital heart programs. STAT category 1 to 3 (lower risk) operations comprised 74% of cases. All outcomes varied significantly across hospitals: adjusted mortality by 3-fold (upper versus lower decile 5.0% versus 1.6%, IDR 3.1 [95% CrI 2.5-3.7]), mean length of stay by 1.8-fold (19.2 versus 10.5 days, IDR 1.8 [95% CrI 1.8-1.9]), and major complications by >3-fold (23.5% versus 7.0%, IDR 3.4 [95% CrI 3.0-3.8]). The degree of variation was similar or greater for low- versus high-risk cases across outcomes, eg, ≈3-fold mortality variation across hospitals for STAT 1 to 3 (IDR 3.0 [95% CrI 2.1-4.2]) and STAT 4 or 5 (IDR 3.1 [95% CrI 2.4-3.9]) cases. High-volume hospitals had less variability across outcomes and risk categories. Simulations suggested potential reductions in deaths (n=282), major complications (n=1539), and length of stay (101 183 days) over the 4-year study period if all hospitals were to perform at the current median or better, with 37% to 60% of the improvement related to the STAT 1 to 3 (lower risk) group across outcomes. CONCLUSIONS We demonstrate significant hospital variation in morbidity and mortality after congenital heart surgery. Contrary to traditional thinking, a substantial portion of potential improvements that could be realized on a national scale were related to variability among lower-risk cases. These findings suggest modifications to our current approaches to optimize care and outcomes in this population are needed.

Abstract
As recovery of congenital heart surgery programs begins during this COVID-19 pandemic, we review key considerations such as screening, protection of patients and health care workers (HCWs), case prioritization, barriers to reactivation, redesign of patient care teams, contribution of telemedicine, modification of trainees' experiences, preparation for potential resurgence, and strategies to maintain HCW wellness. COVID-19 has tested the resolve and grit of our specialty and we have an opportunity to emerge more refined.

Theoretical Model for Delivery of Congenital Heart Surgery in the United States. Ann Thorac Surg 2020; 111:1628-1635.

Abstract
BACKGROUND Over 150 hospitals perform congenital heart surgery (CHS) in the United States. Many hospitals are close together, with a median patient travel distance of 38.5 miles. We began with a theoretical blank slate and used objective methodology guided by population density and volume thresholds to estimate the optimal number and locations of hospitals to provide CHS in the United States. METHODS Guided by published data, we estimated the number of CHS operations in the United States in to be 32,500 per year. We distributed patients geographically based on population density. Metropolitan Statistical Areas (population centers and surrounding areas with close economic/social ties) were used as potential hospital locations. Patients were assigned to the closest hospital location such that all hospitals had a CHS volume of ≥300 operations. RESULTS We estimated 57 hospitals could serve the contiguous United States. Median theoretical hospital volume after regionalization was 451 operations (interquartile range, 366-648). Median patient travel distance was 35.1 miles. Some patients (6396/31,895, 20%) traveled more than 100 miles. CONCLUSIONS Our model suggests the United States could be served by approximately 100 fewer CHS hospitals than currently exist. With hospitals optimally placed, patient travel burden would decrease. This model serves as a platform to improve care delivery by regionalization of CHS.

Unicuspid Aortic Valve Repair Using Geometric Ring Annuloplasty. Ann Thorac Surg 2020; 111:1359-1366. [PMID: 32619617 DOI: 10.1016/j.athoracsur.2020.04.147] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2019] [Revised: 02/01/2020] [Accepted: 04/02/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Unicuspid aortic valves (Sievers type 2 bicuspid) are characterized by major fusion and clefting of the right-left coronary commissure, and minor fusion of the right-noncoronary commissure. Repair has been difficult because of two fusions, variable relative sinus sizes, and peripheral leaflet deficiencies or tears after balloon valvuloplasty. METHODS Twenty unicuspid aortic valves patients underwent valve repair in nine institutions. Right-left major fusion and right-noncoronary minor fusion occurred in 17 of 20 (85%). Commissurotomy was performed on the minor fusion, and a bicuspid annuloplasty ring with circular base geometry and two 180-degree subcommissural posts was sutured beneath the annulus, equalizing the annular circumferences of the fused and nonfused cusps. The nonfused leaflet was plicated, and the cleft in the major fusion was closed linearly until leaflet effective heights and lengths became greater than 8 mm and equal, respectively. RESULTS Average age (mean ± SD) was 22.3 ± 12.3 years (range, 13 to 58), 12 of 20 (60%) were symptomatic, 10 of 20 (50%) required aortic aneurysm resection. Pre-repair hemodynamic data included mean systolic valve gradient 25.8 ± 12.9 mm Hg, aortic insufficiency grade 2.9 ± 1.2, and annular diameter 24.7 ± 3.3 mm. No mortality or major complications occurred. Post-repair annular (ring) size was 20.5 ± 1.3 mm, mean gradient fell to 16.2 ± 5.9 mm Hg, and aortic insufficiency grade decreased to 0.1 ± 0.3 (P < .001). At an average follow-up of 11 months (range, 1 to 22), all 20 patients were asymptomatic and had returned to full activity. CONCLUSIONS Aortic ring annuloplasty reduced annular diameter effectively, recruiting more leaflet to midline coaptation. Minor fusion commissurotomy and annular remodeling to 180-degree commissures converted UAV repair to a simple and reproducible procedure.

Estimating Resource Utilization in Congenital Heart Surgery. Ann Thorac Surg 2020; 110:962-968.

Abstract
BACKGROUND Optimal methods to assess resource utilization in congenital heart surgery remain unclear. We compared traditional cost-to-charge ratio methods with newer standardized cost methods that aim to more directly assess resources consumed. METHODS Clinical data from The Society of Thoracic Surgeons Database were linked with resource use data from the Pediatric Health Information Systems Database (2010 to 2015). Standardized cost methods specific to the congenital heart surgery population were developed and compared with cost-to-charge ratio methods. Resource use in the overall population and variability across hospitals were described using hierarchical mixed effect models adjusting for case-mix. RESULTS Overall, 43 hospitals (65,331 patients) were included. There were minimal population-level differences in the distribution of resource use as estimated by the two methods. At the hospital level, there was less apparent variability in resource use across centers with the standardized cost vs cost-to-charge ratio method, overall (coefficient of variation 20% vs 25%) and across complexity (The Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery [STAT]) categories. When hospitals were categorized into tertiles by resource use, 33% changed classification depending on which resource use method was used (26% by one tertile and 7% by two tertiles). CONCLUSIONS In this first evaluation of standardized cost methodology in the congenital heart population, we found minimal differences vs traditional methods at the population level. At the hospital level, the magnitude of variation in resource use was less with standardized cost methods, and approximately one third of centers changed resource use categories depending on the methodology used. Because of these differences, care should be taken in future studies and in benchmarking and reporting efforts in selecting optimal methodology.
