Pediatr Neonatol 2024; 65:328-335. [PMID: 37923636 DOI: 10.1016/j.pedneo.2023.05.010] [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: 08/19/2022] [Revised: 05/05/2023] [Accepted: 05/25/2023] [Indexed: 11/07/2023] Open
Abstract
OBJECTIVE To summarize echocardiographic characteristics of the anatomy and hemodynamic and clinical outcomes in fetuses with isolated pulmonary stenosis (PS) or pulmonary atresia with intact ventricular septum (PA/IVS). METHODS This was a single-center retrospective study of fetuses with isolated PS or PA/IVS. Echocardiographic variables and clinical outcomes after delivery were evaluated and compared. RESULTS Between 2016 and 2021, 115 livebirths with isolated PS or PA/IVS were included. Proportion of fetuses with mild, moderate and critical PS and PA/IVS was 41.7 %, 18.3 %, 26.1 % and 13.9 %. Fetuses with more severe PS had worse anatomic and hemodynamic profiles. Specifically, the cardiothoracic ratio, pulmonary valve (PV) velocity, degree and velocity of tricuspid regurgitation increased as PS severity increased; and the pulmonary artery/aorta ratio, right ventricle/left ventricle long-axis (TV/MV) ratio, tricuspid valve/mitral valve annulus (TV/MV) ratio, and tricuspid valve inflow duration/cardiac cycle ratio decreased as PS severity increased (P <0.001 for all). PV velocity ≥2 m/s predicted PV pressure ≥40 mm Hg after delivery, with an AUC of 0.81; TV/MV ratio combined with RV/LV ratio predicted clinical outcomes, with an AUC of 0.88. Live births with more severe PS had higher mortality rate (mild 0 vs. moderate 0 vs. critical 11 % vs. PA-IVS 36 %) and lower rate of developing bi-ventricles (mild 100 % vs. moderate 95 % vs. critical 89 % vs. PA-IVS 36 %). CONCLUSION Findings of this study help better understand the anatomy and hemodynamic and clinical outcomes in fetuses with isolated PS or PA/IVS, which could have implications for prenatal counseling and prediction of fetal outcome.

Abstract
Coronary artery fistula, defined as an abnormal communication between the coronary arteries and a cardiac chamber (most commonly) or a thoracic great vessel, may result in hemodynamically significant problems due to vascular shunting in children. Echocardiography, cardiac catheterization, cardiac MRI, and cardiac CT may be used to evaluate coronary artery fistula in children. Recently, CT has played a pivotal role for the accurate diagnosis of coronary artery fistula in children. Surgical or interventional treatment is performed for hemodynamically significant coronary artery fistulas. In this pictorial review, the detailed imaging findings of coronary artery fistula in children are described.

Abstract
This is a case of a female infant with bilateral coronary ostial atresia associated with pulmonary atresia and ventricular septal defect. She developed coronary ischemia at 1-month of age, when she underwent an aortopulmonary shunt and an aorta-right ventricle shunt. The double-orifice tricuspid valve was separating the right ventricle from the left ventricle. She required extracorporeal cardiopulmonary support because of ventricular dysfunction and mitral regurgitation. Although she was temporarily weaned off the support after mitral valvuloplasty, she died from multiple organ failure. To the best of our knowledge, bilateral coronary ostial atresia associated with pulmonary atresia with ventricular septal defect has not been reported previously.

Abstract
BACKGROUND There are a number of surgical and interventional treatment options for infants with pulmonary atresia with intact ventricular septum (PAIVS). In our practice, we characterize coronary fistulae and interruptions with angiography in the newborn and have developed a strategy to safely decompress the right ventricle in association with ligation of fistulae if necessary. METHODS All infants operated for PAIVS at age < 60 days from 1999 to 2018 were retrospectively studied. Pre- and postoperative variables were collected, angiograms were reviewed, and a territory score was created to grade the severity of coronary abnormalities. This study focused on the subgroup of patients who had early surgical decompression of the right ventricle. RESULTS A total of 77 patients were included, with a mean follow-up of 8.6 years. Of these, 55 (71%) had coronary fistulae, including 28 (36%) with coronary artery interruption. Right ventricular decompression (RVD) was performed in 47 (60.5%) patients. There was no 30-day mortality in those who underwent RVD, whereas 6 (20%) without RVD died within 30 days (P = .003). Ten-year survival was 97.8% and 73.3% for RVD and non-RVD, respectively. In order to prevent coronary steal, 17 patients underwent coronary fistula ligation as their RV was decompressed with 100% early and late survival. CONCLUSION Early and late survival in infants with PAIVS is better if the RV can be decompressed. Coronary fistula ligation with RVD has been introduced without an adverse outcome in selected patients with large fistulae.

Abstract
Background Despite remarkable success in the surgical and medical management of congenital heart disease ( CHD ), some survivors still experience cardiovascular complications over the long term. The goal of this study was to evaluate the association between CHD and risk of cardiovascular disease ( CVD ) by conducting a meta-analysis of cohort studies. Methods and Results A systematic literature search of several databases was conducted through April 2018 to identify studies reporting the risk of CVD , stroke, heart failure, and coronary artery heart disease in CHD survivors. The quality of individual studies was assessed using the Newcastle-Ottawa scale. The overall risk estimates were pooled using fixed-effects meta-analysis. Subgroup analyses were performed to explore possible sources of heterogeneity. Nine cohort studies comprising 684 200 participants were included. The overall combined relative risks for people with CHD compared with the controls were 3.12 (95% CI, 3.01-3.24) for CVD , 2.46 (95% CI, 2.30-2.63) for stroke, 5.89 (95% CI, 5.58-6.21) for heart failure, and 1.50 (95% CI, 1.40-1.61) for coronary artery heart disease. Significant heterogeneity was detected across studies regarding these risk estimates. Heterogeneity in the risk estimate of CVD was explained by geographic region, type of study design, sample source, age composition, and controlled confounders. Conclusions This meta-analysis of cohort studies of CHD found an association of increased risk of CVD in later life, although we cannot determine whether this association is confounded by a risk factor profile of CVD among CHD survivors or whether CHD is an independent risk factor.

Abstract
OBJECTIVE We report a single-institute experience of neonatal transvenous radiofrequency pulmonary valve perforation for pulmonary atresia/intact ventricular septum, with echocardiographic predictors of biventricular circulation. METHODS Data were reviewed retrospectively for all neonates who underwent primary transvenous pulmonary valve perforation for pulmonary atresia/intact ventricular septum between January 2008 and November 2018 at our institution. We compared patients who need systemic-to-pulmonary shunt or ductal stenting with patients who did not need. RESULTS During the study period, 31 patients with pulmonary atresia/intact ventricular septum underwent successful radiofrequency pulmonary valve perforation and balloon dilation of the pulmonary valve. There was no procedure-related mortality. Sixteen patients (52%) needed systemic-to-pulmonary shunt or ductal stenting after initial procedure. Among the survivors (follow-up time of 1 to 11.5 years), 15 patients had a biventricular circulation and 6 patients had 1 and 1⁄2 ventricular circulation. Two patients are awaiting for Fontan operation. Both the TV/MV annulus ratio (>0.85) and tricuspid valve z-score (>-1) were found to be a good predictor of a biventricular outcome in our cohort. CONCLUSIONS Percutaneous radiofrequency pulmonary valve perforation and balloon valvotomy is an effective and safe primary treatment strategy for neonates with pulmonary atresia/intact ventricular septum. Ductal stenting or systemic-to-pulmonary shunt may be required in the majority of patients who had smaller right heart components. Preselection of patients according to tricuspid valve z-score and TV/MV annulus ratio allows predicting biventricular circulation.

Abstract
BACKGROUND AND AIMS Suprasystemic pressure waves can damage the coronary arteries resulting in myocardial ischemia and excess early mortality. We aimed to reduce the coronary pressure wave through the sinusoids by abolishing RV volume with percutaneous devices. METHODS AND RESULTS Four patients with PA-IVS and coronary sinusoids from the hypertensive rudimentary RV were evaluated at a median age 26.6 months (range: 2.7-51.7). Right ventricle coronary dependent flow to the left ventricular myocardium was excluded. All four patients had dual perfusion with competitive flow from the RV through the sinusoids to the coronary arteries. Devices used were: Amplatzer vascular plug II of 10-16 mm; 27 coils (diameter 5-15 mm) in the oldest patient. Right ventricular angiography after cavity obliteration showed no more significant coronary perfusion through the sinusoids. There were no complications or deaths. Only minor and transient changes in the levels of troponin were observed. Coronary angiography at pre-Fontan evaluation showed no progress of coronary abnormalities in two patients. CONCLUSION In selected patients with functionally single left ventricle, obliteration of the hypertensive RV cavity by percutaneous devices is safe and abolishes the systolic pressure wave in coronary sinusoids. When performed early, this may halt coronary damage and avoid excess mortality.

Abstract
PURPOSE To assess the intrauterine course, the outcome, and to establish a new prenatal echocardiographic scoring system to predict biventricular (BV) versus univentricular (UV) outcome of fetuses with severe pulmonary stenosis or atresia with intact ventricular septum (PSAIVS). METHODS All cases of PSAIVS diagnosed prenatally over a period of 14years were retrospectively collected in 2 tertiary referral centers. RESULTS Forty-nine fetuses with PSIVS (n = 11) or PAIVS (n = 38) were identified prenatally. Nineteen (38.8%) fetuses had additional ventriculocoronary connections (VCCs) and 21 (42.9%) fetuses had right ventricular hypoplasia. Four (8.2%) pregnancies were terminated, 2 (4.1%) ended in intrauterine fetal death, 4 (8.2%) in neonatal death, and 5 (10.2%) children died in infancy or childhood, including one case with compassionate care. Thirty-four of 44 (77.3%) fetuses with the intention-to-treat were alive at latest follow-up, 25 (73.5%) with BV, and 9 (26.5%) with UV circulation. Most significant predictive markers of UV circulation were Vmax of tricuspid regurgitation (TR) <2 m/s, right ventricle/left ventricle length ratio ≤0.6, and presence of VCC. A scoring system including these 3 markers had 100% sensitivity and 100% specificity predicting an UV outcome if more than one of these criteria was fulfilled. All 25 liveborn infants that were suitable for BV repair survived, whereas only 9 out of 14 candidates for UV repair survived. None of the 14 fetuses with predicted UV outcome would have met the inclusion criteria for fetal intervention, as 10 of them had VCC and the remaining 4 had absent TR or Vmax <2 m/s. CONCLUSION The prognosis of prenatally diagnosed PSAIVS is good if BV circulation can be achieved, while postnatal mortality in UV circulation is high within the first 4 months of life. Postnatal outcome can be predicted prenatally with high accuracy using a simple scoring system. This information is mandatory for parental counseling and may be useful in selecting fetuses for intrauterine valvuloplasty.

Abstract
OBJECTIVES In patients with pulmonary atresia with an intact ventricular septum (PA/IVS), there are no reports about the impact of sinusoidal communication (SC) on left ventricular (LV) performance after a Fontan operation; therefore, the purpose of this study was to fill this gap in the literature. METHODS We performed a single-centre, retrospective study of 46 patients with PA/IVS. Nineteen patients who underwent the Fontan procedure were enrolled and divided into 2 groups: those with SC (SC group) and those without SC (N group). The 2 groups were compared in terms of postoperative cardiac function. RESULTS Thirteen patients were in the SC group (4 patients with right ventricle-dependent coronary circulation) and 6, in the N group. Although 2 of the patients with right ventricular (RV)-dependent coronary circulation showed focal asynergy of the LV wall, others showed no findings of myocardial infarction. The patients' preoperative age and age during the observation period after the Fontan operation did not differ. There was no difference in LV ejection fraction, cardiac index and RV and pulmonary artery pressure before and after the Fontan operation. Preoperative RV volume in the N group was greater than that in the SC group. Brain natriuretic peptide levels were higher in the SC group after the Fontan operation. On ventricular efficacy analysis, contractility was lower (1.8 ± 0.32 vs 2.5 ± 0.40 mmHg/ml/m2, P = 0.001) and ventricular efficacy was worse (1.0 ± 0.15 vs 0.86 ± 0.11, P = 0.046) in the SC group during the postoperative period. CONCLUSIONS Compared to patients with PA/IVS without SC, patients with PA/IVS with SC had a low cardiac contractility and decreased cardiac output efficiency after the Fontan procedure.

Abstract
This article discusses congenital heart defects that are marginal candidates for biventricular repair and highlights the anatomic considerations upon which the surgical decision is based. Specifically, the article reviews the importance of capacitance and compliance of the ventricles and their associated atrioventricular valves. For each of the defects discussed, the imaging modalities used to diagnose a marginal ventricle are reviewed and the surgical decision-making process is outlined. The article also reviews immediate postoperative treatment of these patients and when to consider biventricular repair of a marginal lesion to be a failure.

Abstract
Pulmonary atresia with intact ventricular septum may be complicated by coronary aneurysms and myocardial ischaemia. We report a case of an acquired postoperative right ventricular outflow tract aneurysm with communication to the left ventricular outflow tract. Multimodality imaging helped in the characterisation of this structural abnormality, which led to treatment modification of the patient.

Abstract
BACKGROUND Left ventricular (LV) mechanics in patients with different single morphologic LV subtypes, including tricuspid atresia, double-inlet left ventricle, and pulmonary atresia with intact ventricular septum, remain poorly studied. Given that histologic studies indicate differences in LV myocardial fiber orientation, we hypothesized that this may result in altered LV mechanics. The aim of this study was to evaluate the influence of LV morphology on LV mechanics. METHODS Fifty-two children with single left ventricles after Fontan operation and age-matched control subjects were prospectively enrolled. Using two-dimensional speckle-tracking echocardiography, longitudinal strain was measured in the four-, three-, and two-chamber long-axis planes, and circumferential strain was measured at the basal, mid, and apical short-axis planes. Apical and basal rotation were measured, and twist and torsion were calculated. We compared strain and rotational mechanics in cases versus control subjects and among LV subtypes. RESULTS Compared with control subjects, subjects with single left ventricles had similar LV end-diastolic dimensions but significantly decreased ejection fractions. The single left ventricle cohort had normal global longitudinal strain (P = .20) but lower basal mean circumferential strain (P < .0001). Single left ventricle subjects had higher apical rotation (P = .0001) but decreased basal rotation (P = .0007); there was no difference in twist but increased torsion (P = .001). LV subtypes had different four-chamber (P = .01), two-chamber (P = .006), and global longitudinal strain (P = .01), lowest in the pulmonary atresia with intact ventricular septum subtype. CONCLUSIONS Longitudinal LV strain was preserved in children with single left ventricles after Fontan. A pattern of reduced basal circumferential strain and rotation with an increase in apical rotation and torsion in the single left ventricle cohort may be related to differences in myofiber orientation, increased fibrosis, and the impact of altered loading conditions throughout palliation. Decreased longitudinal strain in the pulmonary atresia with intact ventricular septum group may also reflect detrimental interventricular interactions.

Aortic perfusion score for pulmonary atresia with intact ventricular septum: An antegrade coronary perfusion scoring system that is predictive of need for transplant and mortality. CONGENIT HEART DIS 2017; 13:92-97.

Abstract
BACKGROUND Pulmonary atresia with intact ventricular septum is a unique congenital malformation of the heart in which patients may undergo single-, two- or 1½- ventricle repair. Size of the tricuspid valve annulus, morphology of the right ventricle and presence of ventriculocoronary connections can all impact the selection of appropriate palliative strategy. We developed the aortic perfusion score, a novel scoring system based on anterograde coronary perfusion with the aim of being able to identify patients at risk for death or transplant. METHODS A retrospective study was conducted. Patients were included if an initial catheterization was done prior to any intervention. Each patient was assigned an aortic perfusion score based on the amount of antegrade perfusion to the four main coronary arteries. Various characteristics, including aortic perfusion score, were compared between those who required transplant or died during follow-up vs those who did not. Receiver operator curve analysis was done to determine a cutoff point predictive of a composite endpoint of death or transplant. RESULTS A total of 64 patients were included in the analysis with 10 reaching the composite outcome. An aortic perfusion score of 227.5 predicted the endpoint with a sensitivity of 90% and a specificity of 83%. For each 1-point increase in the APS, the odds of death or transplant decreased by 1.7%. CONCLUSION The aortic perfusion score can be used to predict a composite endpoint of death or transplant and may be helpful in selecting patients that should be listed for transplant.

Abstract
OBJECTIVES The aim of this study was to describe the clinical characteristics, progression, treatment, and outcomes in isolated coronary artery fistula cases diagnosed prenatally. METHODS We carried out a retrospective review of babies diagnosed prenatally with coronary artery fistulas between January, 2000 and December, 2013; five fetuses were included. Echocardiographic features and measurements were noted during pregnancy and after birth. Treatment and outcome were noted. RESULTS Gestational age at initial diagnosis was between 19 and 22 weeks; four coronary artery fistulas originated from the right and one from the left circumflex coronary artery. Drainage was into the right atrium in four cases and into the left ventricle in one case. There was cardiomegaly in two cases at the initial scan. The size of the fistulas increased during pregnancy in all except one. All prenatal diagnoses were confirmed postnatally. Among all, two patients developed congestive cardiac failure soon after birth and required transcatheter closure of the coronary artery fistula, 5 and 17 days after birth, respectively; three patients remained asymptomatic, and all of them showed progressive dilation of the feeding artery and had closure of the fistula at 20 months, 4 years, and 7 years of age, respectively. During the follow-up period, which ranged 2-14 years, all the patients were alive and well. CONCLUSIONS Coronary artery fistulas can be diagnosed accurately during fetal life. Some babies may develop congestive cardiac failure soon after birth requiring early treatment. Those treated conservatively should be kept under review as intervention may be required later.

Abstract
We report the case of a neonate with pulmonary atresia with intact ventricular septum and coronary cameral fistulae despite having a subsystemic right ventricle. We review the literature on coronary cameral fistulae in this disease and right ventricle-dependent coronary circulation. We discuss the potential consequences of this physiology, including risk of adverse cardiovascular events that may impact risk stratification and surgical palliation.

Abstract
Vessels of Wearn are rare findings during coronary angiography in adults. They are known to be associated with forms of cyanotic congenital heart disease in infants but we are not aware of any published cases of association with non-cyanotic left to right shunts in adults. We present the case of a 69-year-old man with angiographically evident vessels of Wearn draining from the left and right coronary arteries into the left ventricle associated with an asymptomatic atrial septal defect. We postulate a developmental phase association between atrial septal maturation and closure of perfusing microchannels from the ventricular cavities to the epicardial coronary arteries on the same spectrum as that which leads to more widespread defects in infants. We also highlight a common medication side effect that might have been mistaken as a manifestation of the congenital anomalies.

Abstract
Anomalous origins of both the left and right coronary arteries are rare but have been well documented when both arteries arise from the pulmonary trunk (Angelini et al., Circulation 105:2449-2454, 2002). An anomalous coronary arterial origin from the pulmonary arteries usually involves the left coronary artery (ALCPA) and less frequently the right coronary artery (ARCPA). At least three cases have been reported in which the right coronary artery arose abnormally from the left ventricle (LV), but none have been reported in which both coronary arteries took their origin from the right ventricle (Ippisch and Kimball, J Am Soc Echocardiogr 23:222.e1-222.e2, 2010; Okuyama et al., Jpn Heart J 36:115-118, 1995; Culbertson et al., Pediatr Cardiol 16:73-75, 1995). Ostial atresia with anomalous origin of a coronary artery from the right ventricle has been described only in pulmonary atresia with an intact ventricular septum and a hypoplastic right ventricle. In this setting, atresia of both coronary ostia with right ventricular origin of both coronary arteries is a rare variant. This report presents a neonate in whom the entire coronary arterial system arose from the right ventricle via a single fistula with no other intracardiac defects. To the authors' knowledge, this anomaly has not been described previously.

Abstract
Obesity, hypertension, and coronary artery disease are prevalent in the general population and well recognized as contributors to cardiac morbidity and mortality. With surgical and medical advances, there is a growing and aging population with congenital heart disease who are also at risk of developing these comorbidities. In addition, some congenital cardiac lesions predispose patients to conditions such as hypertension or coronary artery disease. The effect of these comorbidities on the structurally abnormal heart is not well understood, but might be very important, especially in those with residual abnormalities. Thus, in addition to surveillance for and treatment of late complications it is important for the congenital cardiologist to consider and aggressively manage acquired comorbidities. In this review we explore the prevalence of hypertension, obesity, and coronary artery disease, discuss congenital lesions that predispose to these conditions and review management strategies for this unique population.

Abstract
We present an autopsy case of a male baby born at 35 weeks of gestation with pulmonary atresia with intact ventricular septum (PAIVS), who had coronary blood flow that was dependent on outflow from the right ventricle through the vessels described by Wearn. At 7 weeks of age, he underwent single ventricle palliation consisting of ligation of a patent ductus arteriosus and placement of a modified Blalock-Taussig shunt. The patient experienced a perioperative myocardial infarction, requiring extracorporeal membrane oxygenation. Progressive hemodynamic decline resulted in death 8 days after surgery. Autopsy revealed acute and remote infarctions in both ventricles and fibromuscular dysplasia of the subepicardial and intramural coronary arteries. In 1926, Grant first reported the association between PAIVS and secondary dysplasia of the heart vasculature and hypothesized that the high pressure resulted in dilation of the myocardial sinusoids. Confusion secondary to the unmeritorious dismissal of the myocardial sinusoids has obscured the pathogenesis of PAIVS and led to several publications suggesting second heart field abnormalities as a disease model for PAIVS. We discuss the pathogenesis of PAIVS, the ventriculocoronary arterial connections and the sinusoidal relationship to the vessels described by Wearn, and we attempt to correct the solecism plaguing the nomenclature of myocardial vasculature.

Abstract
OBJECTIVES To determine the impact of fetal echocardiography on the management of pregnancy and of newborns affected by pulmonary atresia and intact ventricular septum (PAIVS) and to evaluate the outcome of infants with and without prenatal diagnosis of PAIVS. METHODS We searched our database for cases of PAIVS prenatally and postnatally diagnosed during the period January 1993-December 2009. Postnatal follow-up was available in all cases included in the study. Karyotyping and fluorescent in situ hybridization analysis for the DiGeorge critical region (22q11.2) were performed in all but one case. RESULTS The study comprised 60 cases of PAIVS: 36 with (Group A) and 24 without (Group B) prenatal diagnosis. In Group A, there were two intrauterine deaths, six postnatal deaths (five early after birth) and one termination of pregnancy. In this group, radiofrequency (RF) perforation was successfully performed in 25 cases; 20/25 infants had a biventricular (BV) repair, without further operation in 13 of them. No patient of Group B died. In this group, RF perforation was successfully performed in 22 cases; 20/22 had a BV repair without further procedure in 15 of them. CONCLUSIONS Prenatal diagnosis of PAIVS allows a reliable prognosis of severity and planning of proper surgical repair strategies. Fetuses that are prenatally diagnosed present a more severe spectrum of the disease; for the cases capable of getting through the neonatal period, the mortality rate and the need for further intervention were not significantly different when compared with babies with only postnatal diagnosis.

Abstract
Sudden death in pulmonary atresia and intact ventricular septum with right ventricular dependent coronary circulation is a well-established complication, and is thought to be caused by myocardial ischaemia. We report a case of paroxysmal complete atrioventricular block that raises the possibility of an additional mechanism of sudden death.

Abstract
Neonates born with hypoplastic left heart syndrome now have a remarkably improved prognosis compared with the situation existing before the development of the Norwood sequence of operative procedures. Some of those born with hypoplastic right ventricles in the setting of pulmonary atresia with an intact ventricular septum, however, still have a relatively poor prognosis. In part this reflects the presence of fistulous communication between the cavity of the right hypoplastic right ventricle and the coronary arterial tree. Such fistulous communications are now increasingly recognised as being important in the setting of hypoplastic left heart syndrome. In this brief review, we describe the anatomy of the communications. Those found with hypoplastic right ventricles are seen most frequently when the cavity of the ventricle effectively represents only the inlet, this in turn reflecting mural overgrowth of the apical trabecular and outlet components during foetal development. This almost certainly reflects an earlier appearance of the pulmonary valvar lesion that promotes the cavitary hypoplasia. In those with hypoplastic left ventricles, the key feature differentiating those with fistulous communications is the presence of a patent mitral valve, since the left ventricle is typically no more than a virtual slit in postero-inferior ventricular wall in the setting of mitral valvar atresia or absence of the left atrioventricular connection.

Abstract
OBJECTIVE To examine early outcomes for pulmonary atresia with intact ventricular septum undergoing single-ventricle palliation and to determine risk factors for mortality. DESIGN Retrospective observational study. SETTING Tertiary paediatric critical care unit. INTERVENTION Risk factors for mortality were sought for infants after the primary intervention whether surgical shunt or ductal stent. MEASUREMENTS AND MAIN RESULTS We reviewed outcomes of 19 infants with pulmonary atresia with intact ventricular septum undergoing single-ventricle palliation between July, 2000 and July, 2008. Echocardiograms, cardiac catheterisation findings, anaesthesia, and critical care management, as well as autopsy reports were reviewed. We modelled survival after surgery and looked for predictors of early mortality. A total of 19 infants underwent single-ventricle palliation and seven of these died. The risk of death was increased by a lower arterial pH at induction of anaesthesia (p = 0.01), a lower systolic blood pressure (p = 0.01), and technical problems during surgery (p = 0.03). On admission to the critical care unit, a lower mixed venous saturation (p = 0.02) and presence of tachyarrhythmia (p = 0.02) were associated with the need for mechanical support within the first 48 hours. CONCLUSIONS There is a high early mortality for those who undergo single-ventricle palliation. It is higher for those who are haemodynamically compromised before surgery; technical problems, and haemodynamic instability during surgery also increase mortality.

Abstract
OBJECTIVE Pulmonary atresia with intact ventricular septum (PAIVS) is a rare cardiac malformation with a broad spectrum of anatomical manifestations, varying from types suitable for biventricular repair to those with diminutive right ventricle and primitive ventriculocoronary connections (VCC), more suitable for single-ventricle palliation or heart transplantation. We sought to test whether tricuspid regurgitation is an easily detectable prenatal criterion with which to identify PAIVS patients at lower risk of needing postnatal single-ventricle palliation. METHOD We identified retrospectively patients with both fetal diagnosis and postnatal confirmation of PAIVS who were seen at Bambino Gesù Hospital between January 2000 and December 2006. Tricuspid valve/mitral valve (TV/MV) ratio, presence and severity of tricuspid regurgitation and direct visualization of VCC were evaluated by echocardiography both pre- and postnatally. RESULTS We identified 22 patients with a prenatal diagnosis of PAIVS. Four pregnancies were terminated and one fetus was lost to follow-up, leaving 17 patients for the analysis. Based on postnatal cardiac catheterization and/or echocardiography we divided our population in two groups: Group 1 included 10 patients with VCC; Group 2 included seven patients without VCC. At fetal echocardiography, tricuspid regurgitation was absent in all ten Group 1 patients and present in all seven Group 2 patients. VCC were seen directly in 6/10 Group 1 patients and in no Group 2 patients. A cut-off value of 0.56 for the TV/MV ratio was highly predictive of VCC during fetal life, with a sensitivity of 100% and a specificity of 90%. CONCLUSIONS The absence of tricuspid regurgitation in fetuses affected by PAIVS is a strong prenatal echocardiographic predictor of VCC, as is a TV/MV ratio < 0.56. Fetuses presenting with tricuspid regurgitation and relatively large right ventricle are at lower risk of needing single-ventricle palliation postnatally. This inforation could be helpful for appropriate prenatal counseling and postnatal decision-making.

Abstract
BACKGROUND The prognosis for pulmonary atresia and intact ventricular septum (PAIVS) has been poor. Our hypothesis is that intrinsic abnormal left ventricular (LV) intramyocardial circulation might be related to the poor outcomes of these patients. METHODS Neonatal heart specimens were examined microscopically in four groups of 6 cases each. Group I had PAIVS with ventriculocoronary artery connections (VCAC), group II had PAIVS without VCAC, group III had normal hearts, and group IV had LV hypertrophy. A projection microscope with grid overlay was used to count the LV intramyocardial coronary artery density (IMCAD), which was expressed as the number of profiles/mm(2). RESULTS The LV IMCAD of groups I (0.40 +/- 0.14/mm(2)) and II (0.45 +/- 0.15/mm(2)) were significantly lower than those of groups III (0.77 +/- 0.11/mm(2)) and IV (0.76 +/- 0.09/mm(2); all with p = 0.002). There was no significant difference between either groups I and II (p = 0.394) or groups III and IV (p = 0.818). CONCLUSIONS This study demonstrates lower LV IMCAD in a widely heterogeneous spectrum of neonatal hearts with PAIVS, which might potentially predispose these patients to myocardial ischemia and in turn contribute to the poor prognosis of this disease.

Abstract
Pulmonary atresia with intact ventricular septum (PAIVS) is a disease with remarkable morphologic variability, affecting not only the pulmonary valve but also the tricuspid valve, the RV cavity and coronary arteries. With advances in interventional techniques and congenital heart surgery, the management of PAIVS continues to evolve. This review is an attempt at providing a practical approach to the management of this disease. The basis of our approach is morphologic classification as derived from echocardiography and angiography. Group A, patients with good sized RV and membranous atresia, the primary procedure at presentation is radiofrequency (RF) valvotomy. Often it is the only procedure required in this group with the most favourable outcome. Patients with severely hypoplastic RV (Group C) are managed along the lines of hearts with single ventricle physiology. The treatment at presentation is patent ductus arteriosus (PDA) stenting with balloon atrial septostomy or conventional modified Blalock Taussig (BT) shunt. Bidirectional Glenn shunt may be done 6-12 months later followed by Fontan completion after a suitable interval. Patients in Group B, the intermediate group, are those with borderline RV size, usually with attenuated trabecular component but well developed infundibulum. The treatment at presentation is RF valvotomy and PDA stenting +/- balloon atrial septostomy. Surgical re-interventions are not uncommonly required viz. bidirectional Glenn shunt when the RV fails to grow adequately (11/2 - ventricle repair) and right ventricular outflow tract (RVOT) reconstruction for subvalvar obstruction or small pulmonary annulus. Catheter based interventions viz. repeat balloon dilatation or device closure of patent foramen ovale (PFO) may also be required in some patients.
