RESUMO
(1) Background: To identify reasons for the persistence of surgical ligation of the patent ductus arteriosus (PDA) in premature infants after the 2019 Food and Drug Administration (FDA) approval of transcatheter device closure; (2) Methods: We performed a 10-year (2014-2023) single-institution retrospective study of premature infants (<37 weeks) and compared clinical characteristics and neonatal morbidities between neonates that underwent surgical ligation before (epoch 1) and after (epoch 2) FDA approval of transcatheter closure; (3) Results: We identified 120 premature infants that underwent surgical ligation (n = 94 before, n = 26 after FDA approval). Unfavorable PDA morphology, active infection, and recent abdominal pathology were the most common reasons for surgical ligation over device occlusion in epoch 2. There were no differences in demographics, age at closure, or outcomes between infants who received surgical ligation in the two epochs; (4) Conclusions: Despite increasing trends for transcatheter PDA closure in premature infants, surgical ligation persists due to unfavorable ductal morphology, active infection, or abdominal pathology.
RESUMO
ABSTRACT: Language-concordant care improves patient satisfaction. Given the increase in Spanish-speaking persons requiring orthopaedic care in the United States, it is essential to increase the Spanish-speaking workforce in orthopaedic surgery. We have proposed strategies to improve the proportion of Spanish-speaking orthopaedic surgeons in the U.S. through early exposure to orthopaedic surgery, by creating collaborative advancement and mentorship opportunities, by endorsing Spanish-language immersion opportunities, and by increasing workforce diversity awareness. Furthermore, we have suggested a strategy to better equip non-Spanish-speaking orthopaedic surgeons while caring for Spanish-speaking patients. Together, the suggested strategies offer a variety of approaches that can have a direct, tangible impact on optimizing orthopaedic care while enhancing patient-physician communication in the Spanish language.

To evaluate short-term procedural outcomes and safety for infants < 2.5 kg who underwent catheterization with intended patent ductus arteriosus (PDA) device closure in a multi-center registry, as performance of this procedure becomes widespread. A multi-center retrospective review was performed using data from the Congenital Cardiac Catheterization Project on Outcomes (C3PO) registry. Data were collected for all intended cases of PDA closure in infants < 2.5 kg from April 2019 to December 2020 at 13 participating sites. Successful device closure was defined as device placement at the conclusion of the catheterization. Procedural outcomes and adverse events (AE) were described, and associations between patient characteristics, procedural outcomes and AEs were analyzed. During the study period, 300 cases were performed with a median weight of 1.0 kg (range 0.7-2.4). Successful device closure was achieved in 98.7% of cases with a 1.7% incidence of level 4/5 AEs, including one periprocedural mortality. Neither failed device placement nor adverse events were significantly associated with patient age, weight or institutional volume. Higher incidence of adverse events associated with patients who had non-cardiac problems (p = 0.017) and cases with multiple devices attempted (p = 0.064). Transcatheter PDA closure in small infants can be performed with excellent short-term outcomes and safety across institutions with variable case volume.

OBJECTIVE: To evaluate patients' ability to return to preinjury activity level after arthroscopically assisted triangular fibrocartilage complex (TFCC) repair. DATA SOURCES: The PubMed electronic library was systematically searched from inception to August 2021 for any eligible articles using a combination of the phrases "TFCC," "return to sport," "return to work," and "athlete." RESULTS: Studies that evaluated patients who had undergone arthroscopic repair of isolated TFCC injury and reported objective or patient-reported outcome measures were included. Fifteen studies representing 478 patients fulfilled the inclusion criteria. An average of 84% of patients were able to fully return to their previous work or sport activities. Most studies reported that range of motion (ROM) and grip strength (GS) both returned to >90% of the contralateral side, and every study that evaluated pain levels found a significant reduction in pain postoperatively. Mayo Modified Wrist Score was reported as excellent or good in 83% of patients, and the average Disabilities of the Arm, Shoulder, and Hand score was 13.8 postoperatively. CONCLUSION: Patients were able to return to their previous work or sport activities at a high rate after TFCC repair, even those participating in more strenuous activities. Measurable functional outcomes of ROM and GS were also reliably restored to near preinjury levels. Patient-reported outcomes of pain and disability were similarly improved after TFCC repair. Current literature has established the long-term success of TFCC repair but is lacking in evaluation of the time points at which patients can expect functional status to be restored.

Single ventricle (SV) anomalies account for one-fourth of all congenital heart disease cases. The existing palliative treatment for this anomaly achieves a survival rate of only 50%. To reduce the trauma associated with surgical management, the hybrid comprehensive stage II (HCSII) operation was designed as an alternative for a select subset of SV patients with the adequate antegrade aortic flow. This study aims to provide better insight into the hemodynamics of HCSII patients utilizing a multiscale Computational Fluid Dynamics (CFD) model and a mock flow loop (MFL). Both 3D-0D loosely coupled CFD and MFL models have been tuned to match baseline hemodynamic parameters obtained from patient-specific catheterization data. The hemodynamic findings from clinical data closely match the in-vitro and in-silico measurements and show a strong correlation (r = 0.9). The geometrical modification applied to the models had little effect on the oxygen delivery. Similarly, the particle residence time study reveals that particles injected in the main pulmonary artery (MPA) have successfully ejected within one cardiac cycle, and no pathological flows were observed.
RESUMO
Pulmonary vein stenosis results from a proliferative process that leads to the progressive obstruction of venous return to the left atrium. It is often resistant to catheterization and surgical based interventions and is frequently fatal when encountered in its severe form. Here, we describe three patients with severe, primary pulmonary vein stenosis that was progressing despite aggressive conventional management strategies. All three patients were initiated on combination chemotherapy with imatinib and sirolimus, drugs which have been previously shown to independently have potential benefit against PVS. Soon after the initiation of these therapies, all three patients experienced a stabilization of their disease process and clinical improvement. All three patients remain alive, with tolerable side effects from the medications. Although early in our experience and with only a small number of patients, combination chemotherapy with imatinib and sirolimus shows promise and merits further investigation as a therapeutic option for this aggressive disease.
RESUMO
The Sano variant of the stage 1 Norwood procedure is commonly performed as initial palliation for hypoplastic left heart syndrome. We present a case of a 2-year-old who developed a mycotic pseudoaneurysm of the Sano graft and discuss the importance of imaging and operative management of this rare presentation. Localization and full description of the lesion require compulsive, often multimodality imaging.

A 13-month-old male sustained cardiac arrest under general anesthesia and was found to have left main coronary artery atresia with collateralization from the right coronary artery. After protracted recovery, the patient underwent coronary ostioplasty. Postoperative imaging confirmed patency of the newly established artery without stenosis. At 12 months, no changes in the vessel were noted. Ventricular function remains mildly decreased and stable.

Approximately [Formula: see text] babies are born with only one functioning ventricle and the Fontan is the third and, ideally final staged palliative operation for these patients. This altered circulation is prone to failure with survival rates below [Formula: see text] into adulthood. Chronically elevated inferior vena cava (IVC) pressure is implicated as one cause of the mortality and morbidity in this population. An injection jet shunt (IJS) drawing blood-flow directly from the aortic arch to significantly lower IVC pressure is proposed. A computer-generated 3D model of a 2-4 year old patient with a fenestrated Fontan and a cardiac output of 2.3 L/min was generated. The detailed 3D pulsatile hemodynamics are resolved in a zero-dimensional lumped parameter network tightly-coupled to a 3D computational fluid dynamics model accounting for non-Newtonian blood rheology and resolving turbulence using large eddy simulation. IVC pressure and systemic oxygen saturation were tracked for various IJS-assisted Fontan configurations, altering design parameters such as shunt and fenestration diameters and locations. A baseline "failing" Fontan with a 4 mm fenestration was tuned to have an elevated IVC pressure (+ 17.8 mmHg). Enlargement of the fenestration to 8 mm resulted in a 3 mmHg IVC pressure drop but an unacceptable reduction in systemic oxygen saturation below 80%. Addition of an IJS with a 2 mm nozzle and minor volume load to the ventricle improved the IVC pressure drop to 3.2 mmHg while increasing systemic oxygen saturation above 80%. The salutary effects of the IJS to effectively lower IVC pressure while retaining acceptable levels of oxygen saturation are successfully demonstrated.

Objective: We previously described the hybrid comprehensive stage II operation as an alternate surgical procedure for a subset of patients with single ventricle congenital heart disease with adequate native ascending aortic outflow. Here we provide a clinical update on the 4 patients who have undergone this procedure. Methods: After undergoing a hybrid approach to the stage I Norwood palliation, the hybrid comprehensive stage II procedure was performed with an incision to the main pulmonary artery (PA), dilation of the ductal stent, creation of a stented baffle between the branch PAs, and a bidirectional Glenn connection. With this approach, dissection of the distal arch and creation of a Damus-Kaye-Stansel anastomosis was avoided. A standard Fontan procedure was planned after the usual period of growth. Results: The first patient, who had trisomy 21 and elevated PA pressures, died postoperatively due to left PA thrombosis. The subsequent 3 patients survived the procedure and remain clinically well. All have required catheterizations for reintervention on their stented intrapulmonary baffles and ductal arches, and all have undergone successful completion of their Fontan procedures. Conclusions: The hybrid comprehensive stage II is a feasible, less complex alternative to the conventional comprehensive stage II operation in a subset of patients with single ventricle physiology. Early postoperative anticoagulation therapy to avoid PA thrombosis is recommended, and restenting of the ductal arch is anticipated. Although the long-term consequences of separate outflow tracts supplying the upper and lower body is unknown, the 3 surviving patients with this circulation are doing well with their Fontan circulation at midterm follow-up.
RESUMO
Background: The hybrid comprehensive stage 2 (HCS2) procedure is a novel palliative operation applicable to a select subset of single ventricle patients with adequate native antegrade aortic flow to the upper body. Flow to the descending aorta, through the pulmonary outlet and ductal arch, is influenced by a stented intrapulmonary baffle connecting the branch pulmonary arteries. We used computational fluid dynamics (CFD) to elucidate the hemodynamic characteristics of this reconstruction. Methods: We used multiscale CFD analysis of a synthetic, patient-derived HCS2 anatomic configuration with unsteady laminar flow conditions and a non-Newtonian blood model to quantify the resultant hemodynamics. The 3-dimensional CFD model was coupled to a 0-dimensional lumped parameter model of the peripheral circulation to determine the required boundary conditions. Results: For the specific anatomy studied, the intrapulmonary baffle did not obstruct flow from the pulmonary trunk to ductal arch as long as the distance between the anterior pulmonary artery wall and baffle wall exceeded â¼7 mm. Vortex shedding off of the baffle wall did not develop, because of the short distance to the ductal arch. The stented baffle experienced significantly uneven "inward" loading from the systemic side. Pulmonary outlet flow separation distal to the baffle produced a low-speed recirculation region. Conclusions: Hemodynamic patterns in this complex anatomy are generally favorable. Low flow recirculation could be mitigated by preoperative shape optimization. Calculated inward stresses on the pulmonary baffle can be used in the future to study baffle stent deformation, which is expected to be small.
RESUMO
Many reports of marijuana-associated myocardial infarct (MI) are limited by incomplete evaluation of the toxicologic exposure, a lack of definitive anatomic findings, and the potential for comorbid coronary atherosclerosis inherent in an adult population. We report a 16-year-old adolescent boy who presented with chest pain after smoking marijuana and was found to have acute MI. Electrocardiogram showed diffuse ST-segment elevations. Exhaustive toxicologic testing confirmed the presence of Δ-9-tetrahydrocannabinol metabolite and ruled out other drugs of abuse. Echocardiography demonstrated moderate global left ventricular systolic dysfunction. Coronary angiography demonstrated no focal coronary lesions or obstruction. Right ventricular septal endomyocardial samples biopsied 36 hours after the onset of pain showed a subendocardial acute MI with a sparse neutrophilic infiltrate. One month after the event, magnetic resonance imaging showed a severely dilated left ventricle and moderately to severely depressed global systolic function. Late gadolinium enhancement consistent with myocardial fibrosis was seen in nearly all myocardial segments. Our unusually well-documented findings strengthen the potential association between marijuana and MI. Furthermore, we demonstrate a disease distribution supporting a process that affects the coronary circulation globally, likely at the distal, small-vessel level.

Introduction New paediatric cardiology trainees are required to rapidly assimilate knowledge and gain clinical skills to which they have limited or no exposure during residency. The Pediatric Cardiology Fellowship Boot Camp (PCBC) at Boston Children's Hospital was designed to provide incoming fellows with an intensive exposure to congenital cardiac pathology and a broad overview of major areas of paediatric cardiology practice. METHODS: The PCBC curriculum was designed by core faculty in cardiac pathology, echocardiography, electrophysiology, interventional cardiology, exercise physiology, and cardiac intensive care. Individual faculty contributed learning objectives, which were refined by fellowship directors and used to build a programme of didactics, hands-on/simulation-based activities, and self-guided learning opportunities. RESULTS: A total of 16 incoming fellows participated in the 4-week boot camp, with no concurrent clinical responsibilities, over 2 years. On the basis of pre- and post-PCBC surveys, 80% of trainees strongly agreed that they felt more prepared for clinical responsibilities, and a similar percentage felt that PCBC should be offered to future incoming fellows. Fellows showed significant increase in their confidence in all specific knowledge and skills related to the learning objectives. Fellows rated hands-on learning experiences and simulation-based exercises most highly. CONCLUSIONS: We describe a novel 4-week-long boot camp designed to expose incoming paediatric cardiology fellows to the broad spectrum of knowledge and skills required for the practice of paediatric cardiology. The experience increased trainee confidence and sense of preparedness to begin fellowship-related responsibilities. Given that highly interactive activities were rated most highly, boot camps in paediatric cardiology should strongly emphasise these elements.

Given the rising costs of health care in today's economic environment, the need for effective, value-driven care has never been more pressing. While the U.S. health care system strives continually to improve patient outcomes, it struggles with the inadequacies due to variation in care and the inefficiencies of unnecessary resource utilization. The tools traditionally used to study care, from retrospective studies to randomized controlled trials, may be inadequate to address the complicated, interdependent questions related to defining effective care. To overcome the deficiencies of these traditional tools and better optimize our health care system, a new kind of methodology is required--one that integrates the functionality of previously existing tools in a novel way. Standardized Clinical Assessment and Management Plans (SCAMPs) were designed to accomplish this goal. A SCAMP is a care pathway, designed by clinicians, to guide medical decision making around a particular disorder. SCAMPs are unique in that they invite knowledge-based diversions from their recommendations and are accompanied by data collection and continuous improvement processes. Through these mechanisms, SCAMPs successfully reduce practice variation, optimize resource use, and create an integrated medical learning system which overcomes many of the inadequacies of traditional research tools. As such, the SCAMP paradigm may represent an important breakthrough in the effort to define and implement effective health care.

Variability in medical practice in the United States leads to higher costs without achieving better patient outcomes. Clinical practice guidelines, which are intended to reduce variation and improve care, have several drawbacks that limit the extent of buy-in by clinicians. In contrast, standardized clinical assessment and management plans (SCAMPs) offer a clinician-designed approach to promoting care standardization that accommodates patients' individual differences, respects providers' clinical acumen, and keeps pace with the rapid growth of medical knowledge. Since early 2009 more than 12,000 patients have been enrolled in forty-nine SCAMPs in nine states and Washington, D.C. In one example, a SCAMP was credited with increasing clinicians' rate of compliance with a recommended specialist referral for children from 19.6 percent to 75 percent. In another example, SCAMPs were associated with an 11-51 percent decrease in total medical expenses for six conditions when compared with a historical cohort. Innovative tools such as SCAMPs should be carefully examined by policy makers searching for methods to promote the delivery of high-quality, cost-effective care.

OBJECTIVE: A Standardized Clinical Assessment and Management Plan (SCAMP) standardizes the care of patients with a predefined diagnosis while actively inviting and collecting data on clinician deviations (DEVs) from its recommendations. For 3 different pediatric cardiac diagnoses managed by SCAMPs, we determined the frequency of, types of, and reasons for DEVs, which are considered to be a valuable source of information and innovation. METHODS: DEVs were collected as part of SCAMP implementation. DEVs were reviewed by the SCAMP committee chairperson and by a separate protocol deviation committee; they were characterized as either justifiable (J), possibly justifiable (PJ), or not justifiable (NJ). RESULTS: We analyzed 415 patients, 484 clinic encounters, and 216 DEVs. Eighty-six (39.8%) of the DEVs were J, 21 (9.7%) were PJ, and 109 (50.4%) were NJ. The percentage of NJ DEVs relative to the number of opportunities for DEV was 4.1%. J and PJ DEVs were mostly due to management of unrelated conditions (11% overall) or special circumstances (22% overall). NJ DEVs primarily involved follow-up intervals (66%) and deleted tests (24%). The reason for deviating from SCAMP recommendations was not given for 31% of DEVs, even though such information was requested. CONCLUSIONS: The overall low rate of NJ DEV suggests that practitioners generally accept SCAMP recommendations, but improved capture of practitioners' reasons for deviating from those recommendations is needed. This analysis revealed multiple opportunities for improving patient care, suggesting that this process can be useful in both promulgating sound practice and evolving improved approaches to patient management.

INTRODUCTION: Despite the growing importance of clinical guidelines, their adoption has encountered significant resistance among clinicians. We developed Standardized Clinical Assessment and Management Plans (SCAMPs) as an innovative, clinician-led approach to building, implementing, and constantly improving flexible guidelines. We hypothesized that SCAMPs would fit well within the culture of medicine and that clinicians would therefore prefer SCAMPs over other guidelines. METHODS: We implemented an anonymous, computer-based survey to analyze provider attitudes toward SCAMPs at our institution. RESULTS: Sixty-nine providers completed the questionnaire (73% response rate). Most providers reported a positive opinion about SCAMPs along axes of overall familiarity (83%), trust (91-94%), utility (75-87%), and overall attitude (64%). Fewer providers felt familiar with the SCAMP improvement process (60% neutral to unfamiliar) or knew that they played a role in this process (62% said no or unsure). Sixty-five percent reported experiencing an erosion in their autonomy with SCAMPs; when comparing this to other guidelines, 38% said other guidelines erode more, 26% felt SCAMPs erode more, and 36% were neutral. The plurality of providers chose SCAMPs as their preferred means to incorporate evidence-based medicine into their practice (46% vs 29% for clinical practice guidelines, 25% for other guidelines). CONCLUSION: Providers look upon SCAMPs favorably and believe that SCAMPs successfully address numerous barriers to guideline adoption. Furthermore, SCAMPs are the preferred means to incorporate evidence-based medicine into practice among providers surveyed. SCAMPs may represent an important step in building guidelines that fit into the culture of medicine, obtain clinician "buy-in," and better influence clinical decision making.
