RESUMEN
This is a case of an infant with duct-dependent pulmonary circulation, who required 6 stents delivered over three procedures to fully stent the arterial duct, which originated in a very unusual fashion. The attainable angiographic projections were unable to profile its origin, and only a CT scan was ultimately able to delineate the (stenotic) ductal origin from the aorta.
RESUMEN
Chronic venous obstructions resulting from indwelling lines, surgery and instrumentation, and congenital anomalies are increasingly common in patients with congenital heart disease (CHD) and other chronic illnesses. Venous obstruction results in threatened long-term vascular access and congestive symptoms. Endovascular therapies are safe and can be effective at rehabilitating obstructed and even occluded veins. The risk of recurrent obstruction is high, however. Post-rehabilitation monitoring and anticoagulation therapy are important, and reinterventions are common. Here, the authors describe techniques to address a variety of venous obstruction lesions that may be encountered in CHD patients and provide illustrative cases.

The surgical pulmonary artery band was first introduced in 1952 and, to this day, can produce challenges in regard to the ideal amount of restriction and the need for reoperations. A transcatheter option may be the ideal solution as it allows for a less-invasive approach for a better hemodynamic assessment and easier re-intervention. To date, multiple approaches have been developed with device modifications to create restrictions to flow, each with advantages and limitations. Continued experience is still necessary to determine the ideal device to use to create an adequate and modifiable level of restriction.

INTRODUCTION: Patients with congenital heart disease are at increased risk for requiring cardiac pacing during their lifetime. METHODS: We present the first described case of using two leadless pacing systems manufactured by separate companies implanted within the same patient to provide atrial and ventricular pacing due to complex congenital anatomy. RESULTS: A 27-year-old male with dextrocardia with double outlet right ventricle, subaortic ventricular septal defect, and pulmonary stenosis status-post pulmonary valve replacement complicated by ventricular pacing dependence and subsequent atrial pacing dependence after atriotomy-based atypical flutter ablation developed recurrent mediastinitis and pocket infection with erosion despite prolonged antibiotic treatment. Due to atrial and ventricular pacing dependence, a comprehensive congenital care team concluded the need for lead extraction and replacement of pacemaker via leadless peacemaking device. Laser-lead extraction and temporary atrial pacemaker placement was performed. Afterward, a transesophageal echocardiogram guided implantation of both a Micra AV 2 (Medtronic) leadless pacemaker in the interventricular septum within the right ventricle and an Aveir (Abbott) leadless pacemaker in the superior base of the right atrial appendage was performed with successful pacing. Although there is no communication between these devices, atrial-mechanical ventricular pacing was reliable with good implant thresholds, impedances and sensing from both devices. CONCLUSION: Our case demonstrates the feasibility of using dual leadless pacing modalities to simultaneously pace someone at complex, prohibitive risk for temporary permanent or permanent pacemaker devices.

Background: Chronic total occlusions in the central venous system limit access and increase morbidity in chronically ill pediatric patients. We report the results of transcatheter recanalization of occluded central veins using angioplasty and stenting. Methods: Patients undergoing successful intervention for venous chronic total occlusions at our institution between April 2013 and December 2019 were retrospectively reviewed. Results: Sixty-eight occluded central veins in 29 patients underwent recanalization with angioplasty (26 veins) or stenting (42 veins). The indications included limited access for catheterization or central line maintenance (19 patients), limb swelling (4 patients), superior vena cava syndrome (3 patients), and pleural effusion (3 patients). The primary risk factor for occlusion was a history of central venous lines after surgery or extracorporeal membrane oxygenation support in 76% of the patients. The median age and weight at the time of initial intervention were 5.8 years and 14.5 kg, respectively. There were no major complications. Of 10 patients with symptoms of venous congestion, 8 experienced symptomatic improvement. Twenty-two patients (59 veins) underwent 44 recatheterizations during a median follow-up duration of 288 days. Early reintervention was typically planned. The median time to recatheterization was 71 days. Twenty-one veins reoccluded and required repeat recanalization. Reocclusion was associated with persistent upstream collateral vein decompression, as determined using postintervention venography (odds ratio, 14.2; 95% CI, 3.3-62.6; P < .001), which was thought to indicate persistently poor venous inflow. Reinterventions were performed on 40 veins. Fifty-two veins that were followed up (88%) remained patent after the most recent intervention. Conclusions: Invasive transcatheter rehabilitation of occluded central veins has the potential to preserve critical access sites and improve the symptoms of venous congestion in pediatric patients. Reinterventions are common for reocclusion, restenosis, and somatic growth.
RESUMEN
Patent ductus arteriosus (PDA) is a frequently encountered defect in infants born extremely premature (≤26 weeks' gestation). Historically, closure of the PDA was performed using cyclooxygenase inhibitor medications or by surgical ligations. However, the benefits of PDA closure using these therapies have never been demonstrated, albeit studies have previously not focused on the extremely premature infants. Therefore, there was a worldwide trend toward conservative management of the PDA. With improved survival of extremely premature infants, comorbidities associated with the PDA has increased, resulting in finding alternate treatments such as transcatheter patent ductus arteriosus closure (TCPC) for this population. Currently, there is a renewed interest toward selective treatment of the PDA in this high-risk cohort of small infants. This Comprehensive Review article inspects the globally changing trends in the management of the PDA in premature infants, with a special focus on the rising adoption of TCPC. Moreover, this article compiles data from several neonatal networks worldwide to help understand the problem at hand. Understanding the current management of premature infants and their outcomes is fundamentally essential if pediatric cardiologists are to offer TCPC as a viable therapeutic option for this population. This article aims to serve as a guide for pediatric cardiologists on this topic by compiling the results on landmark clinical trials on PDA management and the controversies that arise from these trials. Comparative outcomes from several countries are presented, including interpretations and opinions of the data from experts globally. This is a step toward coming to a global consensus in PDA management in premature infants.

When resources in a society are dispersed unevenly, generally through allocation standards, distinct patterns emerge along lines of socially defined categories of people. Power, religion, kinship, prestige, race, ethnicity, gender, age, sexual orientation, and class all play a role in determining who has access to social goods in society. In most cases, social inequality refers to a lack of equality of outcome, but it can also refer to a lack of equality of access to opportunity. Unfortunately, health care is not immune to these social disparities and/or inequalities. These health care disparities in interventional cardiology were recently brought to the forefront by the Society for Cardiovascular Angiography and Interventions (SCAI) as a major focus of 2020-2021. In a recent publication, unique factors leading to disparities were reported to exist among the subsections of interventional cardiology. The congenital heart disease council of SCAI created a task force to further investigate the unique challenges and disparities impacting the practice of congenital heart disease and pediatric cardiology.
RESUMEN
The Society for Cardiovascular Angiography and Interventions (SCAI) Think Tank is a collaborative venture that brings together interventional cardiologists, administrative partners, and select members of the cardiovascular industry community annually for high-level field-wide discussions. The 2021 Think Tank was organized into four parallel sessions reflective of the field of interventional cardiology: (a) coronary intervention, (b) endovascular medicine, (c) structural heart disease, and (d) congenital heart disease. Each session was moderated by a senior content expert and co-moderated by a member of SCAI's Emerging Leader Mentorship program. This document presents the proceedings to the wider cardiovascular community in order to enhance participation in this discussion, create additional dialog from a broader base, and thereby aid SCAI, the industry community and external stakeholders in developing specific action items to move these areas forward.

BACKGROUND: Although rare, coronary artery anomalies can have significant clinical implications. Total anomalous origin of the coronary arteries from the pulmonary artery (TCAPA) represents a rare subtype of coronary artery anomaly for which little is known. The aim of this review was to characterise the presentation, utilised diagnostic modalities, associated cardiac lesions, and treatment strategies in patients with TCAPA. METHODS: A systematic review was performed for cases of TCAPA using PubMed, Embase, and Web of Science. Keywords searched included "total anomalous origin of the coronary arteries from the pulmonary artery," "single ostium anomalous coronary artery from the pulmonary artery," and "anomalous origin of both coronary arteries from the pulmonary artery." RESULTS: Fifty-seven cases of TCAPA were identified in 50 manuscripts. Fifty-eight per cent of patients were male and the median age at presentation was 10 days (mean 1.71 ± 6.6 years, range 0 days-39 years). Most patients were symptomatic at the time of presentation; cyanosis (n = 22) and respiratory distress (n = 14) were the most common symptoms. Cases were most commonly diagnosed at autopsy (n = 26, 45.6%), but operative intervention was pursued in 22 cases (45.6%); aortic re-implantation (n = 14) and a Takeuchi-type repair (n = 7) were the most common routes of repair. CONCLUSIONS: The clinical presentation of patients with TCAPA was found to be variable, likely related to the presence of associated cardiac lesions. TCAPA should be considered in patients with suspected anomalous origin of the left coronary artery from the pulmonary artery for the serious consequences that can occur if not promptly corrected.

Pulse oximetry oxygen saturation (SpO 2 )-based critical congenital heart disease (CCHD) screening is effective in detection of cyanotic heart lesions. We report a full-term male infant with normal perfusion who had passed the CCHD screening at approximately 24 hours after birth with preductal SpO 2 of 99% and postductal SpO 2 of 97%. Detection of a loud systolic cardiac murmur before discharge led to the diagnosis of pulmonary atresia (PA) with ventricular septal defect (PA-VSD) by echocardiogram. The infant was transferred to a tertiary care center after initiation of prostaglandin E1 (PGE1) therapy. Throughout the initial course, he was breathing comfortably without respiratory distress or desaturations on pulse oximetry. We believe that this is the first documented report of PA missed by CCHD screening. Thorough and serial clinical examinations of the newborn infant proved vital in the timely diagnosis of this critical disease. We review the hemodynamics and the recent literature evaluating utility of CCHD screening in the diagnosis of PA-VSD. Pulse oximetry-based CCHD screening should be considered a tool to enhance CCHD detection with an emphasis on detailed serial physical examinations in newborn infants.
