Pediatr Cardiol 2024; 45:722-728. [PMID: 38411710 DOI: 10.1007/s00246-024-03430-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 01/23/2024] [Indexed: 02/28/2024]
Abstract
Pulmonary balloon valvuloplasty (PBV) is the treatment of choice for subjects with isolated pulmonary valve stenosis (IPS). The purpose of this study was to define fetal echocardiographic features associated with an inpatient PBV prior to newborn hospital discharge and characterize resource utilization of IPS fetuses among participating centers. Six center, retrospective case series of singleton fetuses identified between 2010 and 2020 with IPS. Third-trimester echocardiogram data was compared with postnatal data, included pulmonary valve Doppler velocities, pulmonary valve insufficiency and ductus arteriosus flow direction. Comparison between subjects who underwent inpatient PBV during their newborn hospital admission versus those infants referred for outpatient PBV after initial hospital discharge. We analyzed data by logistic regression, student t test and Chi-Square testing with a p value of ≤ 0.05 considered statistically significant. Forty-nine IPS fetuses were identified. Thirty-eight (78%) underwent inpatient PBV at 5 (range 1-58) days and 11 (22%) underwent outpatient PBV at 51.8 (11-174) days. Newborns requiring an inpatient PBV were more likely to have one or more characteristics on 3rd-trimester fetal echocardiogram: left to right or bidirectional ductus arteriosus flow (61% vs 0%), and/or a peak pulmonary valve velocity > 3.0 m/s (odds ratio 16.9, 95% confidence interval 3.02-94.17) with a sensitivity of 90.4% and specificity of 97.7%. Ductus arteriosus flow direction and pulmonary valve peak velocity in the 3rd trimester can successfully predict the need for newborn inpatient PBV. We speculate these findings may be useful in choosing delivery site for the pregnancy complicated by fetal IPS.

Abstract
There is conclusive evidence for relief of pulmonary valve obstruction immediately after balloon pulmonary valvuloplasty (BPV) and at follow-up. Development of infundibular obstruction is seen in more severe PS cases and in older subjects. Reappearance of PS was observed in approximately 10 % of patients following BPV. The reasons for recurrence were found to be balloon/annulus ratio less than 1.2 and immediate post-BPV pulmonary valve peak gradients greater than 30 mmHg. Recurrent stenosis is successfully addressed by repeating BPV with lager balloons than used initially. Long-term results revealed continue relief of obstruction, but with development of pulmonary insufficiency, some patients requiring replacement of the pulmonary valve. It was concluded that BPV is the treatment of choice in the management valvar PS and that balloon/annuls ratio used for BPV should be lowered to 1.2 to 1.25. It was also suggested that strategies should be developed to prevent/reduce pulmonary insufficiency at long-term follow-up.

Abstract
Congenital heart disease (CHD) accounts for nearly one-third of all congenital defects, and patients often require repeated heart valve replacements throughout their lives, due to failed surgical repairs and lack of durability of bioprosthetic valve implants. This objective of this study is to develop and in vitro test a fetal transcatheter pulmonary valve replacement (FTPVR) using sutureless techniques to attach leaflets, as an option to correct congenital defects such as pulmonary atresia with intact ventricular septum (PA/IVS), in utero. A balloon expandable design was analyzed using computational simulations to identify areas of failure. Five manufactured valves were assembled using the unique sutureless approach and tested in the fetal right heart simulator (FRHS) to evaluate hemodynamic characteristics. Computational simulations showed that the commissural loads on the leaflet material were significantly reduced by changing the attachment techniques. Hemodynamic analysis showed an effective orifice area of 0.08 cm2, a mean transvalvular pressure gradient of 7.52 mmHg, and a regurgitation fraction of 8.42%, calculated over 100 consecutive cardiac cycles. In conclusion, the FTPVR exhibited good hemodynamic characteristics, and studies with biodegradable stent materials are underway.

Right Heart Remodeling After Pulmonary Valve Replacement in Patients With Pulmonary Atresia or Critical Stenosis With Intact Ventricular Septum. J Am Heart Assoc 2023; 12:e031090. [PMID: 37929755 PMCID: PMC10727386 DOI: 10.1161/jaha.123.031090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 09/28/2023] [Indexed: 11/07/2023]
Abstract
Background Patients with pulmonary atresia or critical pulmonary stenosis with intact ventricular septum (PA/IVS) and biventricular circulation may require pulmonary valve replacement (PVR). Right ventricular (RV) remodeling after PVR is well described in tetralogy of Fallot (TOF); we sought to investigate RV changes in PA/IVS using cardiac magnetic resonance imaging. Methods and Results A retrospective cohort of patients with PA/IVS who underwent PVR at Boston Children's Hospital from 1995 to 2021 with cardiac magnetic resonance imaging before and after PVR was matched 1:3 with patients with TOF by age at PVR. Median regression modeling was performed with post-PVR indexed RV end-diastolic volume as the primary outcome. A total of 20 patients with PA/IVS (cases) were matched with 60 patients with TOF (controls), with median age at PVR of 14 years. Pre-PVR indexed RV end-diastolic volume was similar between groups; cases had higher RV ejection fraction (51.4% versus 48.6%; P=0.03). Pre-PVR RV free wall and left ventricular (LV) longitudinal strain were similar, although LV midcavity circumferential strain was decreased in cases (-15.6 versus -17.1; P=0.001). At a median of 2 years after PVR, indexed RV end-diastolic volume was similarly reduced; cases continued to have higher RV ejection fraction (52.3% versus 46.9%; P=0.007) with less reduction in RV mass (Δ4.5 versus 9.6 g/m2; P=0.004). Post-PVR, RV and LV longitudinal strain remained unchanged, and LV circumferential strain was similar, although lower in cases. Conclusions Compared with patients with TOF, patients with PA/IVS demonstrate similar RV remodeling after PVR, with lower reduction in RV mass and comparatively higher RV ejection fraction. Although no differences were detected in peak systolic RV or LV strain values, further investigation of diastolic parameters is needed.

Abstract
BACKGROUND Cardiovascular diseases with increased right ventricular (RV) afterload induce RV diastolic and systolic dysfunction, and myocardial fibrosis in humans. Studies in dogs with pulmonary stenosis (PS) evaluating RV diastolic function and markers of myocardial fibrosis are lacking. HYPOTHESIS/OBJECTIVES Dogs with PS have echocardiographic evidence of RV diastolic and systolic dysfunction and increased serum concentrations of galectin-3 (Gal-3), a surrogate biomarker for myocardial fibrosis. ANIMALS Forty client-owned dogs (10 controls, 30 with PS). METHODS Prospective study. All dogs had systemic blood pressure measurement, serum biochemical analysis, echocardiography, and measurement of serum Gal-3 concentration performed. RESULTS Variables of RV diastolic function were obtained in 39/40 dogs. Trans-tricuspid flow velocity in early diastole to trans-tricuspid flow velocity in late diastole ratios (RV E/A) were lower (P < .001) in dogs with PS (median, 0.94; range, 0.62-2.04) compared to controls (1.78; 1.17-2.35). Trans-tricuspid flow velocity in early diastole to tricuspid annular myocardial velocity in early diastole ratios (RV E/e') were higher (P < .001) in dogs with PS (11.55; 4.69-28) compared to control (6.21; 5.16-7.21). Variables of RV systolic function were lower in dogs with PS (P = <.001). Serum Gal-3 concentration was higher (P = .002) in dogs with PS (285.1 pg/mL; 94.71-406.97) compared to control dogs (162.83 pg/mL; 52.3-232.82). CONCLUSIONS AND CLINICAL IMPORTANCE Dogs with PS have RV diastolic and systolic dysfunction, and increased Gal-3 concentrations. These findings suggest the presence of RV myocardial fibrosis in dogs with PS, which could impact clinical management.

Abstract
Newborns with congenital heart disease often require interventions linked to high morbidity and mortality rates. In the last few decades, many transcatheter interventions have become the first-line treatments for some critical conditions in the neonatal period. A catheter-based approach provides several advantages in terms of procedural time, length of hospitalization, repeatability and neurodevelopmental issues (usually related to cardiopulmonary bypass). The main transcatheter procedures will be reviewed, as they are now valid alternatives to conventional surgical management.

Abstract
INTRODUCTION/OBJECTIVES Pulmonary stenosis (PS) is a congenital defect in the dog that is managed with balloon valvuloplasty (BV). Obstruction severity is routinely assessed using transthoracic echocardiography. The objectives of this study were to describe the short-term changes and long-term restenosis by retrospectively evaluating flow-dependent and flow-independent echocardiographic variables for dogs with PS after BV. ANIMALS, MATERIALS, AND METHODS Medical records and stored echocardiographic images were reviewed from dogs that received BV for PS. The following echocardiographic variables were measured or calculated: maximum systolic ejection velocity (VmaxPV) and velocity-derived maximal pressure gradient (PV maxPG) across the pulmonary valve; ratio of aortic to pulmonary velocity time integral (VTIAV/VTIPV); ratio of aortic to pulmonary maximal velocity. RESULTS Eighty-one dogs with PS that had a BV were included. Each of these dogs had pulmonary obstruction severity assessed in at least three timepoints. Forty-nine dogs had at least one additional examination performed, the last of which occurred a median of 504 days after the BV. Echocardiographic variables at the first follow-up had increased by a clinically relevant quantity in 20-34% of the dogs when comparing to the immediate post-BV examination. The last follow-up examination identified valve restenosis in 18-38% of the dogs in this study. Valve type and pre-BV obstruction severity did not have a significant effect (P > 0.1). CONCLUSIONS For the assessment of BV efficacy, the immediate post-BV echocardiogram may not be as useful as the first follow-up examination several months later. Pulmonary restenosis after BV may be more prevalent than previously reported.

Abstract
For neonates with critical congenital heart disease requiring intervention, transcatheter approaches for many conditions have been established over the past decades. These interventions may serve to stabilize or palliate to surgical next steps or effectively primarily treat the condition. Many transcatheter interventions have evidence-based records of effectiveness and safety, which have led to widespread acceptance as first-line therapies. Other techniques continue to innovatively push the envelope and challenge the optimal strategies for high-risk neonates with right ventricular outflow tract obstruction or ductal-dependent pulmonary blood flow. In this review, the most commonly performed neonatal transcatheter interventions will be described to illustrate the current state of the field and highlight areas of future opportunity.

Abstract
Objective To evaluate the effectiveness of the procedure and outcomes during follow-up. Methods 80 patients with pulmonary valvular stenosis who underwent percutaneous balloon valvuloplasty between January 2014 and December 2019 are described. Demographic, echocardiographic, and hemodynamic characteristics of the procedure were evaluated. Follow-up included clinical, echocardiographic parameters, pulmonary regurgitation severity, and residual pulmonary gradient at each cutoff point. Results The age range was 2 years (interquartile range: 10.5 months - 6 years), and the predominant sex was male with 56.2%. The transvalvular pulmonary gradient decreased from 61.7 mmHg +- 21.2 to 17 mmHg (interquartile range: 11-26 mmHg). The immediate success rate was 90%. Follow-up time showed a median of 21 months (interquartile range: 5-47.5 months). All patients at follow-up showed some degree of pulmonary insufficiency at each cutoff point; 17% of the cases at the end of their follow-up were found to have severe insufficiency. Three cases of long-term restenosis were found (3.8%), and 6 (7.5%) were admitted for valvuloplasty surgery or pulmonary valve replacement. The complications reported reached 10% of cases, two patients were admitted to surgery during the procedure for major complications. A significant association was found with severe pulmonary insufficiency at the end of follow-up and ring/balloon ratio. Conclusions Percutaneous transluminal valvuloplasty with balloon is an effective technique in the treatment of pulmonary valvular stenosis, with reported complications but with good results during follow-up.

Abstract
Background and objectives During the last decades, the survival rates in patients with congenital heart disease have increased dramatically, particularly in patients with complex heart malformations. However, the survival in patients with simple defects is still unknown. We aimed to determine the characteristics and the risk of mortality in patients with isolated pulmonary valve stenosis (PS). Methods Swedish inpatient, outpatient and cause of death registries were used to identify patients born between 1970 and 2017 with a diagnosis of PS, without any other concomitant congenital heart lesion. For each patient with PS, 10 control individuals without congenital heart disease were matched by birth year and sex from the total population registry. We used median-unbiased method and Kaplan-Meier survival analysis to examine the risk of mortality. Results We included 3910 patients with PS and 38 770 matched controls. The median age of diagnosis of PS was 0.7 years (IQR 0.3–7.0). During a median follow-up of 13.5 years (IQR 6.5–23.5), 88 patients with PS and 192 controls died; 500 patients with PS (12%) underwent at least one transcatheter or surgical valve intervention. The overall mortality rate was significantly higher in patients with PS compared with matched controls (HR 4.67, 95% CI 3.61 to 5.99, p=0.001). Patients with an early diagnosis of PS (0–1 year) had the highest risk of mortality (HR 10.99, 95% CI 7.84 to 15.45). Conclusions In this nationwide, register-based cohort study, we found that the risk of mortality in patients with PS is almost five times higher compared with matched controls. Patients with an early diagnosis of PS appears to be the most vulnerable group and the regular follow-up in tertiary congenital heart units may be the key to prevention.

Abstract
Percutaneous balloon pulmonary valvuloplasty (PBPV) is the primary treatment for pulmonary valve stenosis (PVS). The study consisted of 228 children with PVS who underwent PBPV from January 2004 to October 2019 at a single center. The risk factors for ≥moderate pulmonary regurgitation (PR), residual stenosis, and restenosis were analyzed based on the baseline patient characteristics and measured value of corresponding inspection results. Among 228 patients, follow-up results were obtained in 193 patients. The univariate analysis demonstrated that young age, low weight, small pulmonary annulus diameter, higher initial RV-PA PSEG, increased RV/systemic pressure ratio, and severe PVS were associated with ≥moderate PR. The multivariate analysis demonstrated that higher initial RV-PA PSEG and low weight were independently associated with ≥moderate PR, while higher initial RV-PA PSEG was independently associated with residual stenosis and restenosis. PBPV is a preferred tre atment in PVS children with a higher success rate. Higher initial RV-PA PSEG was a significant factor for ≥moderate PR, residual stenosis, and restenosis.

Abstract
Transcatheter balloon valvuloplasty for the treatment of aortic and pulmonary valve stenosis was first described nearly 40 years ago. Since that time, the technique has been refined in an effort to optimize acute outcomes while reducing the long-term need for reintervention and valve replacement. Balloon pulmonary valvuloplasty is considered first-line therapy for pulmonary valve stenosis and generally results in successful relief of valvar obstruction. Larger balloon to annulus (BAR) diameter ratios can increase the risk for significant valvar regurgitation. However, the development of regurgitation resulting in right ventricular dilation and dysfunction necessitating pulmonary valve replacement is uncommon in long-term follow-up. Balloon aortic valvuloplasty has generally been the first-line therapy for aortic valve stenosis, although some contemporary studies have documented improved outcomes following surgical valvuloplasty in a subset of patients who achieve tri-leaflet valve morphology following surgical repair. Over time, progressive aortic regurgitation is common and frequently results in the need for aortic valve replacement. Neonates with critical aortic valve stenosis remain a particularly high-risk group. More contemporary data suggest that acutely achieving an aortic valve gradient <35 mm Hg with mild aortic regurgitation may improve long-term valve performance and reduce the need for valve replacement. Continued study will help to further improve outcomes and reduce the need for future reinterventions.

Repeat balloon valvuloplasty for dogs with recurrent or persistent pulmonary stenosis. J Vet Cardiol 2021; 34:29-36.

Abstract
INTRODUCTION/OBJECTIVES Pulmonary stenosis (PS) is a common congenital defect in the dog. Severe valvar PS can be treated with balloon valvuloplasty (BV) to reduce obstruction severity and improve clinical signs. Repeat BV is often unnecessary, as restenosis is uncommon. Repeated pulmonary BV in people is generally successful and safe, but outcomes in dogs with recurrent or persistent stenosis have not been reported. The objectives of this study were to retrospectively evaluate outcomes of repeat BV in dogs. ANIMALS, MATERIALS, AND METHODS Medical records and stored echocardiographic images were reviewed from dogs that received repeat BV for pulmonary valvar restenosis or persistent stenosis. Echocardiographic variables included maximum systolic ejection velocity (PVmax), velocity-derived maximal pressure gradient (PGmax) and velocity time integral (VTI) across the pulmonary valve, and ratios of pulmonic to aortic maximum velocity (PVmax/AVmax) and VTI (VTIPV/VTIAV). RESULTS Twenty-three dogs were included; one underwent three BV procedures. The median time between BV procedures was 18.3 months (interquartile range, 6.3-43.6). One dog died during repeat BV, but no others experienced adverse effects. Reductions in PVmax, PGmax, and VTIPV after initial and repeat BV were 1.85 m/s, 76.2 mmHg, and 44.7 cm and 1.33 m/s, 55.6 mmHg, and 30.2 cm, respectively (all p < 0.01). Differences between pre-BV and post-BV PVmax, PGmax, VTIPV, PVmax/AVmax, and VTIPV/VTIAV were not different comparing initial to repeat BV (all p > 0.10). CONCLUSIONS Repeat BV for recurrent or persistent PS is well tolerated and effective in a majority of dogs.

Abstract
Pulmonary valve stenosis (PVS) accounts for approximately 10% of all congenital heart defects. Echocardiography and right heart catheterization are the gold standards for diagnosis of PVS and for assessing disease severity and responsiveness to treatment.Recently, cardiac magnetic resonance imaging (cMRI) has been established as an important tool to comprehensively evaluate cardiac structure and function; however, research into the usefulness of cMRI for PVS management is limited. Here, we describe a case of a 59-year-old female with isolated, severe PVS who was successfully treated with balloon pulmonary valvuloplasty (BPV) followed by sequential cMRI at 1 and 12 months. Exertional dyspnea and elevated plasma BNP concentration were observed 1 month after BPV; however, echocardiographic findings did not indicate recurrent stenosis or increased pulmonary valve regurgitation but an increase in mitral E/e'. cMRI demonstrated improved systolic forward flow and RV function with enlargement of LV volume, and the rapid increase in LV preload might be associated with the transient deterioration in symptoms and BNP level, which both gradually improved within 3 months after BPV. cMRI further depicted that a reduced RV mass index and increased RV cardiac output were achieved gradually during the follow-up period.In conclusion, cMRI in combination with echocardiography was sufficiently informative to follow-up this PVS patient both before and after BPV. cMRI is easily reproducible in adult patients; therefore, cMRI should be recommended for long-term follow-up in adult PVS patients.

Abstract
Although parents are typically the most appropriate decision-makers for their children, there are limits to this authority. Medical providers may be ethically obligated to seek state intervention against a parental decision if the parent places a child at significant and imminent risk of serious harm. When parents make medical decisions for their children, they assess both the projected benefits and risks of their choices for their family. These assessments are impacted by uncertainty, which is a common feature of neonatal intensive care. The relative presence or absence of uncertainty may impact perceptions of parental decisions and a medical provider's decision to seek state intervention to overrule parents. In this article, we propose a model integrating prognostic uncertainty into pediatric decision-making that may aid providers in such assessments. We will demonstrate how to apply this model to 3 neonatal cases and propose that the presence of greater uncertainty ought to permit parents greater latitude to incorporate family values into their decision-making even if these decisions are contradictory to the recommendations of the medical team.

[PMID: 31975534 DOI: 10.1002/jmri.27034] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Revised: 12/10/2019] [Accepted: 12/11/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Right ventricular dilation and dysfunction is a common long-term complication in patients with repaired pulmonary stenosis (rPS). Additionally, abnormal right and left ventricular interactions have been reported in right-sided heart defect after intervention, including in pulmonary stenosis. PURPOSE To analyze ventricular strain, remodeling, and left and right ventricular interactions in rPS patients with preserved right ventricular ejection fraction (RVEF) compared with healthy children using cardiac magnetic resonance. STUDY TYPE A cross-sectional study. POPULATION In all, 34 rPS patients and 10 healthy children volunteers (controls). FIELD STRENGTH/SEQUENCE 3.0T/2D balanced steady-state free precession (2D b-SSFP) cine, late gadolinium enhancement (LGE), and 2D phase contrast (2D-PC). ASSESSMENT Pulmonary regurgitation (PR) fractions of the main pulmonary artery, biventricular volumes, masses, function, and cardiac strain. STATISTICAL TESTS Mann-Whitney U-test, t-test, Pearson correlation coefficients, Spearman's correlation coefficients, and intraclass correlation coefficients analysis were performed. RESULTS For group analysis, the right ventricular (RV) global circumferential strain and radial strain were significantly increased in patients when compared with controls (-13.57 ± 2.69 vs. -5.91 ± 3.16, P < 0.001; 25.31 ± 8.12 vs. 9.87 ± 5.32, P < 0.001, respectively). The fraction of PR displayed moderate correlation with right ventricular end-diastolic volume index (RVEDVi) (r = 0.452, P = 0.022). RVEDVi and mass index were larger in patients vs. control (104.92 ± 27.46 vs. 85.15 ± 11.98, P = 0.016; 18.28 ± 4.95g/m2 vs. 11.67 ± 2.14 g/m2 , P < 0.001, respectively). Patients presented with preserved left ventricular ejection function, but was lower than healthy controls (60.89% ± 4.89% vs. 65.95% ± 4.56%, P = 0.006). Regional circumferential strain of segment 3 of left ventricle (LV) were significantly decreased in patients (-7.79 ± 6.52 vs. -13.56 ± 3.22, P = 0.003). DATA CONCLUSION Compensated increased RV strain, myocardial remodeling of RV, and adverse right and left ventricular interactions occur in rPS patients with preserved RVEF. The decreased interventricular septum strain may lead to impaired LV function due to RV dilation as a result of PR. LEVEL OF EVIDENCE 3 Technical Efficacy Stage: 3 J. Magn. Reson.

Abstract
BACKGROUND Right ventricular (RV) dilation from pulmonary valve regurgitation (PR) is common after intervention(s) for pulmonary stenosis (PS) or atresia and intact ventricular septum (PA/IVS). It is not well established whether PR and RV dilation have similar effects on RV function and exercise capacity in these patients compared to patients after repair of tetralogy of Fallot (rToF). The aims of this study were to compare exercise tolerance, RV function and myocardial mechanics in non-ToF versus rToF children with significantly increased and comparable RV volumes. METHODS Thirty PS or PA/IVS children after intervention(s) with significant PR and RV dilation (non-ToF group) were retrospectively matched for RV end-diastolic volume index (RVEDVi) and age with 30 rToF patients. Clinical characteristics, RV function by echocardiography and CMR, ECG and exercise capacity were compared between groups. RESULTS The groups were well matched for RVEDVi and age. Global RV function (RVEF: 48.7 ± 6.4% vs. 48.5 ± 7.2%, P = .81) and exercise capacity (% predicted peak VO2:82.5 ± 17.7% vs. 75.6 ± 20.4%, P = .27) were similarly reduced between groups. RVEDVi correlated inversely with RVEF in both groups (non-ToF:r = -0.39, P = .04, rToF:r = -0.40, P = .03). QRS duration was wider in rToF patients, and in both groups inversely correlated with RVEF (non-ToF:r = -0.77, P < .001, rToF:r = -0.69, P < .001). In contrast to global function, longitudinal RV strain was lower in rTOF vs non-TOF (-20.1 ± 3.9 vs.-25.7 ± 4.4, P < .001). CONCLUSIONS Global RV function and exercise capacity are similarly reduced in non-ToF and rToF patients with severely dilated RV, after matching by RVEDVi, suggesting a comparable impact of RV dilation on RV global function. The significance of reduced RV longitudinal function and worse dyssynchrony in rToF patients require further exploration.

Am J Cardiol 2018; 121:1617-1623.

Abstract
Outcome data for neonates with critical pulmonary stenosis (PS) is limited. We aimed to review the outcomes after balloon pulmonary valvuloplasty (BPV) for neonates with critical PS at our institution. All neonates with critical PS who underwent BPV from 1990 to 2017 were included. A total of 44 neonates underwent BPV for critical PS. Nonright ventricular dependent coronary artery fistulas was seen in 6/44 (13.6%) patients. Tricuspid valve z-scores were -1.9 (interquartile range [IQR] -3.04, -0.48) in those with coronary artery fistulas as compared with -0.27 (IQR -0.5, 0.8) in those without (p = 0.03). Fifteen of forty-four subjects (34.1%) patients underwent reintervention with 10 patients (22.7%) requiring an alternate source of pulmonary blood flow (3 patients subsequently underwent right ventricular overhaul, 2 underwent Glenn operations, and 1 underwent repeat BPV). Five patients underwent reintervention for right ventricular outflow tract obstruction. Pulmonary valve annulus z-score was significantly smaller in those who needed reintervention -2.4 (IQR -2.9 to -0.95) versus -0.59 (IQR -1.3, -0.15); p = 0.02. At a median follow-up of 8.2 (IQR 3.4 to 13.1) years, moderate or severe pulmonary regurgitation was seen in 22/42 (53.7 %) patients with biventricular circulation, 3 requiring pulmonary valve repair/replacement. In conclusion, coronary artery fistulas occur in a significant number of patients with critical pulmonary stenosis, occurring more frequently in patients with small tricuspid valves. Reintervention is required for 1/3 of patients. Patients with small pulmonary valve annuli are more likely to undergo reintervention for right ventricular outflow tract obstruction. Significant pulmonary regurgitation is common and may require eventual pulmonary valve replacement.

Abstract
Congenital pulmonary vascular anomalies are typically found in infancy or early childhood however, some may remain silent and present in adult patients. Anomalies may be separated into anatomic categories based on involvement of the pulmonary arteries, pulmonary veins or both with or without involvement of the lung parenchyma. Association with congenital heart disease and other syndromes is very common. Computed tomography (CT) and magnetic resonance imaging (MRI) are both invaluable at assessment of these anomalies allowing for both diagnosis and detailed treatment planning. This article will focus primarily on the use of CT, as the high resolution evaluation of the lung parenchyma is also important in many of these conditions. In young patients especially, rapid heart rate and concerns of radiation exposure are important considerations when performing CT. This article will discuss scan techniques as well as clinical diagnostic considerations and basic endovascular treatment of congenital pulmonary vascular anomalies.

Abstract
PURPOSE OF REVIEW Our review is intended to provide readers with an overview of disease processes involving the pulmonic valve, highlighting recent outcome studies and guideline-based recommendations; with focus on the two most common interventions for treating pulmonic valve disease, balloon pulmonary valvuloplasty and pulmonic valve replacement. RECENT FINDINGS The main long-term sequelae of balloon pulmonary valvuloplasty, the gold standard treatment for pulmonic stenosis, remain pulmonic regurgitation and valvular restenosis. The balloon:annulus ratio is a major contributor to both, with high ratios resulting in greater degrees of regurgitation, and small ratios increasing risk for restenosis. Recent studies suggest that a ratio of approximately 1.2 may provide the most optimal results. Pulmonic valve replacement is currently the procedure of choice for patients with severe pulmonic regurgitation and hemodynamic sequelae or symptoms, yet it remains uncertain how it impacts long-term survival. Transcatheter pulmonic valve replacement is a rapidly evolving field and recent outcome studies suggest short and mid-term results at least equivalent to surgery. The Melody valve® was FDA approved for failing pulmonary surgical conduits in 2010 and for failing bioprosthetic surgical pulmonic valves in 2017 and has been extensively studied, whereas the Sapien XT valve®, offering larger diameters, was approved for failing pulmonary conduits in 2016 and has been less extensively studied. Patients with pulmonic valve disease deserve lifelong surveillance for complications. Transcatheter pulmonic valve replacement is a novel and attractive therapeutic option, but is currently only FDA approved for patients with failing pulmonary conduits or dysfunctional surgical bioprosthetic valves. New advances will undoubtedly increase the utilization of this rapidly expanding technology.
