ABSTRACT

Importance: The treatment of neonates with irreparable heart valve dysfunction remains an unsolved problem because there are no heart valve implants that grow. Therefore, neonates with heart valve implants are committed to recurrent implant exchanges until an adult-sized valve can fit. Objective: To deliver the first heart valve implant that grows. Design, Setting, and Participants: Case report from a pediatric referral center, with follow-up for more than 1 year. Participants were a recipient neonate with persistent truncus arteriosus and irreparable truncal valve dysfunction and a donor neonate with hypoxic-ischemic brain injury. Intervention: First-in-human transplant of the part of the heart containing the aortic and pulmonary valves. Main Outcomes and Measures: Transplanted valve growth and hemodynamic function. Results: Echocardiography demonstrated adaptive growth and excellent hemodynamic function of the partial heart transplant valves. Conclusions and Relevance: In this child, partial heart transplant delivered growing heart valve implants with a good outcome at age 1 year. Partial heart transplants may improve the treatment of neonates with irreparable heart valve dysfunction.

ABSTRACT

BACKGROUND: The natural history of the dilated truncal root in repaired truncus arteriosus (TA) is incompletely understood. METHODS: A single-center review of patients who underwent TA repair between January 1984 and December 2018 was performed. Echocardiographically determined root diameters and derived z scores were measured at the annulus, sinus of Valsalva (SoV), and sinutubular junction (STJ) immediately before TA repair and throughout follow-up. Linear mixed-effects models assessed trends in root dimensions over time. RESULTS: Of 193 patients who underwent TA repair at a median age of 12 days (interquartile range, 6-48 days) and survived to discharge, 34 (17.6%), 110 (57.0%), and 49 (25.4%) patients had bicuspid, tricuspid, and quadricuspid truncal valves, respectively. Median postoperative follow-up was 11.6 years (interquartile range, 4.4-22.0 years; range, 0.1-34.8 years). Truncal valve or root intervention was required in 38 patients (19.7%). The mean rates of annular, SoV, and STJ growth were 0.7 ± 0.3 mm/y, 0.8 ± 0.5 mm/y, and 0.9 ± 0.4 mm/y, respectively. Root z scores remained stable with time. At baseline, compared with patients with tricuspid leaflet anatomy, bicuspid patients had larger diameters at the SoV (P = .003) and STJ (P = .029), whereas quadricuspid patients had larger STJ diameters (P = .004). Over time, the bicuspid and quadricuspid cohorts demonstrated comparatively greater annular dilatation (both P < .05). Patients with ≥75th percentile root growth rates had a higher incidence of moderate-severe truncal regurgitation (P = .019) and truncal valve intervention (P = .002). CONCLUSIONS: Root dilatation in TA persisted for up to 30 years after primary repair. Patients with bicuspid and quadricuspid truncal valves demonstrated greater root dilatation over time and required more valve interventions. Continued longitudinal follow-up is warranted in this higher-risk cohort.

ABSTRACT

Truncus arteriosus, also referred to as common arterial trunk (CAT), is generally classified as a cyanotic congenital heart disease characterized by a single arterial trunk arising from the heart and supplying both pulmonary and systemic circulations. Cyanosis exists by virtue of it being an admixture lesion. We report a 13-year-old boy diagnosed to have type 1 CAT who was acyanotic at presentation and had all features of an operable lesion even at this age. He underwent a successful repair with closure of the subtruncal VSD and insertion of a hand-sewn valved right ventricle-to-pulmonary artery conduit made of bovine pericardium and Gore-Tex membrane.

ABSTRACT

OBJECTIVES: Common Arterial Trunk (CAT) continues to have a very poor prognosis globally. To address that, we have developed a novel technique targeting key concepts for the correction of all components of the anomaly, using autologous arterial tissue. This aims to enhance results, availability worldwide, and importantly to avoid the need for repeated reoperations. METHODS: From January 2019 to 4 January 2021, all patients with isolated CAT had repair of the defect using autologous arterial trunk tissue with direct right ventricle (RV) to pulmonary artery (PA) connection. Clinical outcomes, follow-up which included multi-slice computed tomography 3D segmentation and 4D cardiovascular magnetic resonance flow, are presented. RESULTS: Twenty patients were included in the study (median age 4.5 months). There were 2 hospital deaths due to systemic infection and pulmonary hypertensive crisis, respectively. Following discharge all patients remained asymptomatic with no signs of heart failure and improved pattern of growth (median follow-up: 8 months). Early postoperative 3D segmentation showed a conical shaped neo-right ventricular outflow chamber connecting the body of the RV to the main PA through a valveless ostium, and normal crossing of PA and neo-aorta. 4D cardiovascular magnetic resonance pattern of flow showed normal rapid laminar flow through the atrioventricular valves followed by a vortex towards the outflow tracts. There was laminar flow through the neo-aorta and neo-PA with velocity not exceeding 2.5 m/s. The PA regurgitant fraction was 25 ± 5% and was limited to early diastole. CONCLUSIONS: The initial results of utilizing the key concepts, using autologous arterial tissue for the repair of CAT, are encouraging, both clinically and by multimodality imaging.

ABSTRACT

We report an anterior translocation of the right pulmonary artery procedure to relieve severe left bronchial obstruction that was caused by right pulmonary artery stent placement in a 1-year-old patient with truncus arteriosus and interrupted aortic arch. After neonatal repair, the patient re-presented with severe truncal valve regurgitation, right pulmonary artery stenosis, and severe biventricular dysfunction, which was treated with truncal valve repair and right pulmonary artery plasty. The patient suffered from left bronchial compression from right pulmonary artery stent placement, which was successfully treated by the translocation procedure. Bronchial stenosis was successfully relieved by the translocation procedure. Indications, advantages, and disadvantages of this procedure are discussed.

ABSTRACT

We studied conduit-related risk factors for mortality, conduit reintervention, conduit replacement, and pulmonary artery (PA) reinterventions after truncus repair. Patients who underwent truncus repair at our institution between 1995 and 2019 were studied. Cox proportional hazards modeling evaluated variables for association with mortality, time to conduit reintervention, time to conduit replacement, and time to PA reintervention. Truncus was repaired in 107 patients at median age of 17 days (IQR 9-45). Median follow-up time was 7 years. Aortic homografts were implanted in 57 (53%) patients, pulmonary homograft in 40 (37%), and bovine jugular conduit in 10 (9%). Median conduit size was 11 mm (IQR 10-12) and median conduit Z-score was 1.71 (IQR 1.08-2.34). At 5 years, there was 87% survival, 21% freedom from conduit reinterventions, 37% freedom from conduit replacements, and 55% freedom from PA reinterventions. Conduit size (HR 0.7, 95%CI 0.4-1.4, p=.41) and type (aortic homograft reference; bovine jugular vein graft HR 0.6, 95% CI 0.08-5.2, p=.69; pulmonary homograft HR 0.7, 95% CI 0.2-2.3, p=.58) were not associated with mortality. On multivariate analysis, the hazard for conduit reintervention, conduit replacement, and PA reintervention decreased with increasing conduit Z-score values of 1 to 2.5 (non-linear relationship, p<.01), with little additional reduction in hazard beyond this range. Implantation of a larger conduit within Z-score values of 1 and 2.5 is associated with a decreased hazard for conduit reintervention, conduit replacement, and PA reintervention after truncus repair. The type and size of the conduits did not impact mortality.

ABSTRACT

A 6-month-old, female, domestic shorthair cat weighing 1.8 kg presented with cardiomegaly seen on radiographs taken at a primary care veterinary center. Echocardiography revealed a single enlarged vessel overriding a ventricular septal defect and severe hypertrophy of the right ventricular free wall. There was no evidence of a pulmonary arterial trunk originating from the heart. The blood flow through the ventricular septal defect exhibited right-to-left shunting. The cat suddenly experienced dyspnea and died at home, and a postmortem examination was performed. A single large vessel was noted leaving the heart, from which the right and left pulmonary arteries arose separately; a main pulmonary artery was absent. There was only one single anomalous coronary ostium that arose from the brachiocephalic artery and divided into two branches. The walls of the extracardiac coronary artery were thick, but neither infarcts nor narrowing was observed within the coronary arteries. There were no abnormalities in the intracardiac coronary artery. These findings revealed a persistent truncus arteriosus with an anomalous coronary artery. A combination of these anomalies might have contributed to the early death of the cat.

ABSTRACT

Hemitruncus arteriosus refers to an uncommon congenital cardiovascular abnormality. It usually presents in infancy and leads to the development of pulmonary hypertension, heart failure, and in severe cases maybe death. Herein, we reported hemitruncus arteriosus in a 10-day-old neonate with respiratory distress, patent ductus arteriosus, and thrombocytopenia.

ABSTRACT

Resumen Introducción: La detección de cardiopatías congénitas en la etapa neonatal a partir de un soplo cardiaco o cianosis no es efectiva. Las cardiopatías congénitas críticas, como el tronco arterioso común (TAC), causan la mayoría de las muertes neonatales por malformaciones congénitas. El tamizaje por oximetría de pulso en los recién nacidos detecta hasta el 70% de estas cardiopatías. El TAC presenta una alta mortalidad en el primer año de vida. Caso clínico: Se presenta el caso de un paciente de sexo femenino de 4 años de edad con soplo cardiaco, palpitaciones, disnea y cianosis perioral, con diagnóstico al nacimiento de soplo inocente. Se detectó TAC mediante una ecocardiografía. Las resistencias vasculares pulmonares fueron evaluadas por medio de cateterismo cardiaco derecho, con hallazgo de hipertensión arterial pulmonar y vasorreactividad pulmonar. Se realizó corrección quirúrgica. A la fecha, la hipertensión arterial pulmonar continúa presente, por lo que se implementó Bosentan® (Actelion, USA) como tratamiento a largo plazo. Conclusiones: En recién nacidos, el tamizaje por oximetría de pulso después de las 24 horas de vida es un método efectivo para el diagnóstico oportuno de cardiopatías congénitas críticas antes de los signos de colapso cardiovascular. Por ello, resulta una herramienta diagnóstica fundamental para reducir la morbimortalidad. Aunque la corrección quirúrgica de cardiopatías congénitas con hipertensión arterial pulmonar es factible en algunos pacientes, su manejo subsecuente es complejo e impacta de manera adversa en la calidad de vida.


Abstract Background: The detection of congenital heart disease in newborns, based on a heart murmur or cyanosis is not effective. Critical congenital heart diseases, such as truncus arteriosus (TA), cause most of neonatal deaths due to congenital malformations. The screening for pulse oximetry in newborns detects up to 70% of these heart diseases. TA presents high mortality in the first year of life. Case report: A 4-year-old female patient with a heart murmur, palpitations, dyspnea, and perioral cyanosis was diagnosed with an innocent heart murmur at birth. TA was detected by echocardiography. Pulmonary vascular resistances were evaluated through right cardiac catheterization, and pulmonary arterial hypertension and pulmonary vasoreactivity were diagnosed as well. Surgical correction was performed. Currently, pulmonary arterial hypertension persists, for which Bosentan® (Actelion, USA) has been implemented as a long-term treatment. Conclusions: In newborns, the pulse oximetry screening after 24 hours of life is an effective method for suitable diagnosis of critical congenital heart disease before the signs of cardiovascular collapse. Therefore, it has become an essential diagnostic tool to reduce morbidity and mortality. Although the surgical correction of congenital heart disease with pulmonary arterial hypertension is feasible in some patients, its subsequent management is complex and has an adverse impact on the quality of life.

ABSTRACT

BACKGROUND: Elevated pulmonary vascular resistance (PVR) is common following repair of truncus arteriosus. Inhaled nitric oxide (iNO) is an effective yet costly therapy that is frequently implemented postoperatively to manage elevated PVR. OBJECTIVES: We aimed to describe practice patterns of iNO use in a multicenter cohort of patients who underwent repair of truncus arteriosus, a lesion in which recovery is often complicated by elevated PVR. We also sought to identify patient and center factors that were more commonly associated with the use of iNO in the postoperative period. DESIGN: Retrospective cohort study. SETTING: 15 tertiary care pediatric referral centers. PATIENTS: All infants who underwent definitive repair of truncus arteriosus without aortic arch obstruction between 2009 and 2016. INTERVENTIONS: Descriptive statistics were used to demonstrate practice patterns of iNO use. Bivariate comparisons of characteristics of patients who did and did not receive iNO were performed, followed by multivariable mixed logistic regression analysis using backward elimination to identify independent predictors of iNO use. MAIN RESULTS: We reviewed 216 patients who met inclusion criteria, of which 102 (46%) received iNO in the postoperative period: 69 (68%) had iNO started in the operating room and 33 (32%) had iNO initiated in the ICU. Median duration of iNO use was 4 days (range: 1-21 days). In multivariable mixed logistic regression analysis, use of deep hypothermic circulatory arrest (odds ratio: 3.2; 95% confidence interval: 1.2, 8.4) and center (analyzed as a random effect, p = .02) were independently associated with iNO use. CONCLUSIONS: In this contemporary multicenter study, nearly half of patients who underwent repair of truncus arteriosus received iNO postoperatively. Use of iNO was more dependent on individual center practice rather than patient characteristics. The study suggests a need for collaborative quality initiatives to determine optimal criteria for utilization of this important but expensive therapy.

ABSTRACT

The first human mutations in GATA6 were described in a cohort of patients with persistent truncus arteriosus, and the phenotypic spectrum has expanded since then. This study underscores the broad phenotypic spectrum by presenting two patients with de novo GATA6 mutations, both exhibiting complex cardiac defects, pancreatic, and other abnormalities. Furthermore, we provided a detailed overview of all published human genetic variation in/near GATA6 published to date and the associated phenotypes (n = 78). We conclude that the most common phenotypes associated with a mutation in GATA6 were structural cardiac and pancreatic abnormalities, with a penetrance of 87 and 60%, respectively. Other common malformations were gallbladder agenesis, congenital diaphragmatic hernia, and neurocognitive abnormalities, mostly developmental delay. Fifty-eight percent of the mutations were de novo, and these patients more often had an anomaly of intracardiac connections, an anomaly of the great arteries, and hypothyroidism, compared with those with inherited mutations. Functional studies mostly support loss-of-function as the pathophysiological mechanism. In conclusion, GATA6 mutations give a wide range of phenotypic defects, most frequently malformations of the heart and pancreas. This highlights the importance of detailed clinical evaluation of identified carriers to evaluate their full phenotypic spectrum.

ABSTRACT

Persistent truncus arteriosus (PTA) is a relatively uncommon congenital heart disease, accounting for approximately 0.7-1.4% of all congenital cardiac abnormalities worldwide. PTA is usually accompanied by a single semilunar valve, with leaflets ranging from one to six in number. However, absent semilunar valve (ASV) is rarely seen in PTA. Here, we report a case of prenatally diagnosed PTA accompanied by ASV (PTA-ASV) confirmed by postmortem autopsy.

ABSTRACT

OBJECTIVES: Preoperative moderate or greater truncal valve (TV) insufficiency is one of the most important factors influencing mortality in children with truncus arteriosus. We therefore sought to determine the impact of TV insufficiency and concomitant TV surgery on children who underwent truncus arteriosus repair at a single institution. METHODS: We reviewed 180 patients who underwent truncus arteriosus repair between 1979 and 2016. Preoperative echocardiography demonstrated TV insufficiency in 80 patients (mild: 33.9%, 61/180; moderate: 9.4%, 17/180 and severe: 1.1%, 2/180). RESULTS: Twenty-one patients had concomitant TV surgery with an early mortality of 19% (4/21) and overall survival of 70.8 ± 10.1% at 25 years. There were 60 neonates, 11 of whom had concomitant TV surgery with an early mortality of 27% (3/11) and overall survival of 62.3 ± 15.0% at 20 years. Concomitant TV repair (P = 0.5) was not a risk factor for death. TV reoperation was common in those who had concomitant TV surgery, with freedom from reoperation of 19.2 ± 14.9% at 20 years. In the remaining 159 patients, 14 required subsequent TV surgery, and the freedom from TV surgery was 84.0 ± 4.6% at 20 years. At a median follow-up of 18.5 years, TV insufficiency was none or trivial in 79.6% (109/137) and mild or less in 98.5% (135/137) of patients. CONCLUSIONS: Most patients with mild TV insufficiency are free from TV surgery up to 25 years. The durability of TV repair is poor. Most patients with moderate or greater TV insufficiency and a quadricuspid TV will require TV surgery.
