Abstract
OBJECTIVES Studies focused on infants with univentricular heart undergoing stage I palliation other than the Norwood procedure remain a topic of great interest. This study evaluated the outcome of infants who underwent systemic to pulmonary shunt (SPS) or pulmonary artery banding (PAB). METHODS Infants who underwent SPS or PAB as stage I palliation between 1994 and 2019 were included. Survival and late systemic ventricular function were evaluated. RESULTS Out of 242 patients, 188 underwent SPS (77.7%) and 54 PAB (22.3%). Main diagnosis included tricuspid atresia, unbalanced atrioventricular septal defects, double inlet left ventricles and single ventricles with other morphology. Thirty-eight patients died before stage II palliation (15.7%). Stage II palliation was performed in 182 patients (75.2%), and mortality between stages II and III was 11 (5.6%). Stage III palliation was performed in 160 (66.1%) patients. Survival at 1, 5 and 15 years after stage I procedure was 81.9, 77.1 and 76.2%, respectively, and similar between both procedures (P = 0.97). Premature birth [P = 0.03, hazard ratio (HR) = 2.1], heterotaxy (P = 0.006, HR = 2.4) and dominant right ventricle (P = 0.015, HR = 2.2) were factors associated to mortality. Unbalanced atrioventricular septal defect (P = 0.005, HR = 4.6) was a factor associated to systemic ventricular dysfunction. CONCLUSIONS In patients with univentricular heart who underwent SPS and PAB as stage I palliation, survival at 15 years was 76%, regardless of th chosen approach. Premature birth, heterotaxy and dominant right ventricle were associated to mortality.

Ann Pediatr Cardiol 2020; 14:26-34. [PMID: 33679058 PMCID: PMC7918013 DOI: 10.4103/apc.apc_128_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 06/27/2020] [Accepted: 08/05/2020] [Indexed: 11/21/2022] Open
Abstract
Background: The standard first stage palliation for univentricular heart with unrestricted pulmonary blood flow (PBF) is surgical pulmonary artery (PA) banding for which the ideal age is within the first 8 weeks of life. This study aimed to look for the utility of PA band done beyond 3 months of age for patients presenting beyond the stipulated period. Materials and Methods: This is a retrospective analysis of the outcome of twenty patients with single ventricle (SV) physiology with unrestricted PBF who presented late and were selected on the basis of clinical, radiological, and echocardiographic parameters for PA banding. Results: The median age of the patients was 5.5 months (3.5–96 months), and the median body weight was 4.7 kg (3.2–22.0 kg). The patients were divided into three groups as follows: ten patients between 3 and 6 months of age (Group A), seven patients between 6 months to 1 year of age (Group B), and three patients > 1 year of age with additional features of pulmonary venous hypertension (Group C). The mean reduction of PA pressures following PA band was 60.9%, 48.8%, and 58.3% and the mean fall in oxygen saturation was 10.4%, 8.0%, and 6.6% in the three groups, respectively. The postoperative mortality rate was 10%. The mean follow up duration was 13.5 months (7–23 months). There was a statistically significant improvement in weight for age Z scores following PA band (P = 0.0001). On follow up cardiac catheterization, the mean PA pressures were 16.6 (±3.6), 22.7 (±5.7), and 33.3 (±12.4) mmHg, respectively, in the three groups, and the mean pulmonary vascular resistance index was 1.86 (±0.5), 2.45 (±0.7), and 3.5 (±1.6) WU.m2, respectively. Subsequently, seven patients in Group A, three patients in Group B, and one patient from Group C underwent successful bidirectional Glenn (BDG) surgery. Conclusions: Late PA band in selected patients with SV physiology can have definite benefit in terms of correction of heart failure symptoms and subsequent conversion to BDG and can potentially change the natural history of disease both in terms of survival and quality of life.

Abstract
The aim of this study was to determine the optimal timing of pulmonary artery band (PAB) placement in neonates with single ventricle physiology, unrestricted pulmonary blood flow, and no systemic outflow tract obstruction. Retrospective chart review of all patients who underwent isolated PAB for single ventricle physiology between January 2005 and December 2014 was carried out. The influence of age at the time of PAB on operative mortality, the need for reoperation to adjust the PAB, the preparedness of the pulmonary vascular bed prior to the second-stage bidirectional cavopulmonary shunt (BCPS), and the outcomes following BCPS were studied. The study cohort included 54 subjects (34 males). The median age at the time of PAB was 18 days. The overall mortality following PAB was 4 % (2/54). Reoperation for PAB adjustment was 7 % (4/54). Younger age at the time of PAB was not associated with mortality or increased risk of reoperation. There was a mild positive correlation between the age at PAB and the mean pulmonary artery pressure prior to BCPS. There was also a weak positive correlation between the age at PAB and the duration of ventilation following BCPS. Age at the time of PAB did not influence pulmonary vascular resistance (PVR) prior to BCPS or the mortality and hospital stay following BCPS. PAB can be done safely and effectively soon after birth in neonates with single ventricle physiology, increased pulmonary blood flow, and no potential or actual systemic outflow tract obstruction. It may not be necessary to wait for a few weeks after birth for the neonatal PVR to fall before placing a PAB.

Abstract
Background: The objective of this study was to assess the results of the pulmonary artery (PA) banding in patients with congenital heart defects (CHD) and pulmonary hypertension (PH) in the current era. Methods: We analyzed data from 305 patients who underwent PA banding between April 2005 and April 2010 at our centre. All patients were approached through a left thoracotomy. Twenty percent of patients underwent PA banding based on Trusler's rule (Group 1), 55% of them underwent PA banding based on PA pressure measurement (Group 2), and the rest of them (25%) based on surgeon experience (Group 3). The follow-up period was 39 ± 20 month and 75% of patients (230 cases) had definitive repair at mean interval 23 ± 10 months. Results: The rate of anatomically and functionally effectiveness of PA banding in all groups was high (97% and 92%, respectively). There were no significant differences in anatomically and functionally efficacy rate between all groups (P=0.77, P=0.728, respectively). There was PA bifurcation stenosis in six cases (2%), and pulmonary valve injury in one case (0.3%). The mortality rate in PA banding was 2% and in definitive repair was 3%. Conclusions: We believe that PA banding still plays a role in management of patients with CHD, particularly for infants with medical problems such as sepsis, low body weight, intracranial hemorrhage and associated non cardiac anomalies. PA banding can be done safely with low morbidity and mortality.

Abstract
OBJECTIVE We examined whether the socio-economic circumstances of a developing country justify pulmonary artery banding (PAB) for the deferral of perceived high-risk patients requiring biventricular repair. METHODS A retrospective cohort analysis was done on 143 consecutive patients with ventricular anatomy suitable for a biventricular repair, who had a pulmonary artery band applied between 1 January 2002 and 31 December 2007 as they were considered too high a risk to undergo corrective surgery. The goal in all patients was to lower their risk of definitive surgery by improving their clinical condition. The minimum follow-up period was 2 years with the closing date for data collection being 31 January 2010. The mean weight and age at PAB was 5.34 ± 2.94 kg and 9.9 ± 17.3 months. The endpoints of the study were mortality, interval hospital readmission, growth pattern post-banding, whether or not definitive correction was achieved, and the current follow-up status of uncorrected patients. RESULTS The hospital mortality was 8% (n = 12), the inter-stage mortality 21% (n = 30), and the total mortality 29% (n = 42). Positive growth was not shown in 50% following the banding procedure. The mean number of inter-current hospital admissions was 1.5 ± 2 times per patient. At the termination of data collection, after a mean interval of 24.5 ± 14.3 months, debanding and full correction was achieved in 43% (n = 62). In addition to the 29% (n = 42) that were confirmed to be dead, an additional 28% (n = 39) were not corrected and of these almost half were regarded as lost to follow-up. Thus, of the entire cohort of patients, 57% (n = 81) have not achieved definitive correction at the termination of data collection. CONCLUSION A strategy of deferring biventricular repair by the application of a pulmonary artery band is ineffective under Third World conditions largely due to lack of patient compliance. This study shows that the overall mortality in the inter-stage period following PAB is high prior to definitive correction. Less than half of patients will eventually be repaired in a reasonable time frame and patient follow-up is unreliable. We conclude that consideration should be given to early definitive repair even in perceived high-risk cases.

Abstract
BACKGROUND Pulmonary artery banding is proposed as a first palliation in infants with complex congenital heart disease and high pulmonary blood flow. In addition, it may be used to retrain the left ventricle. Optimal tightening may be difficult to obtain, leading to reoperation. An implantable device for pulmonary artery banding with telemetric control was recently developed allowing for repeated adjustments, but it is presently limited to patients weighing less than 20 kg. In large animals, we tested an off-label adjustable gastric banding system for pulmonary artery banding. METHODS AND RESULTS Fourteen ewes weighing 50 to 75 kg underwent implantation of the Lap-Band device (BioEnterics Corp, Santa Barbara, Calif) around the main pulmonary artery through a left thoracotomy. All had functional evaluation with progressive occlusion and opening of the device at implantation and every 2 weeks until sacrifice immediately after implantation (group 1, n = 8), at 1 month (group 2, n = 3), at 3 months (group 3, n = 3), or death. Invasive pressure measurements in the right ventricle and aorta were carried out each time. Devices were easily implanted in all animals. Progressive occlusion and reopening were possible in all animals during each time point. Two animals died of right heart failure related to excessive tightening of the band. Retrieval of the device without any major damage was possible in 12 of 14 animals. CONCLUSION With this implantable device, we were able to adjust the pulmonary artery diameter in animals. Patients requiring left ventricle retraining and weighing more than 30 kg would benefit from the device's use in humans.

Abstract
The palliation of the cyanotic child with a dominant morphologically left ventricle, discordant ventriculo-arterial connections, and obstruction to the pulmonary outflow tract has continued to evolve and mature. The evolution began in the early days of surgical palliation with the Blalock-Taussig shunt, extended to construction of cavopulmonary shunts, if required, and then to the Fontan procedure and its subsequent modifications. This journey took nearly 30 years to complete. There is increasing clinical data to document the beneficial effects of this approach, with ever-improving outcomes. Some aspects of the history of the cavopulmonary shunt have been previously reviewed in this journal and elsewhere, as have analysis of outcomes for some groups of patients considered for surgical completion of the Fontan circulation. While there has been some ongoing interest in ventricular septation since the early success of Sakakibara et al., this approach has largely been abandoned. Considerably more challenges and debate resonate in the surgical algorithms defined for patients whose hearts are characterized by a dominant left ventricle, discordant ventriculo-arterial connections, and unobstructed flow of blood to the lungs. This latter group will be the focus of this review, as will the aetiology of the myocardial hypertrophy that is particularly frequent in this group of patients, its clinical recognition, indeed its anticipation, and the multiple surgical strategies designed to prevent or treat it. All these manoeuvres are considered to optimise suitability for, and outcome from, creation of the Fontan circulation.

Abstract
OBJECTIVE Banding of the pulmonary artery might be required to prevent pulmonary vascular damage in patients with increased pulmonary artery flow and to retrain the left ventricle in preparation for an arterial switch operation in patients with congenitally corrected transposition of the great arteries. Readjustment of the pulmonary artery band might be required in the postoperative period. In this study we aimed to test the feasibility of a novel device for bidirectionally adjustable pulmonary artery constriction. METHODS A hydraulic main pulmonary artery occluder was implanted in lambs and gradually inflated to create right ventricular pressure overload at a systemic (aortic) level. During the following period (up to 12 weeks), this pressure overload was monitored by measuring aortic and right ventricular pressures by means of implanted subcutaneous reservoirs. If required to maintain the right ventricular pressure overload at a systemic level in the growing animals, the occluder was deflated through a third subcutaneous reservoir. RESULTS After the banding period (average of 64 +/- 8 days), the main pulmonary artery cuff could still be adjusted, and the animals showed no clinical signs of heart failure. Histologic analysis of the pulmonary artery showed extensive fibrosis, a giant cell response around the device, and small areas of tissue necrosis; complete transmural necrosis was not detected. CONCLUSIONS This device allows adjustment of the pulmonary artery cuff in a precise manner over a prolonged period of time without surgical reintervention. Potentially, the device might have applications for clinical use in children with congenital heart disease.

Abstract
BACKGROUND The mortality of pulmonary artery banding improved significantly in the 1980s. However, we lack information on this procedure in the current era. METHODS The results of pulmonary artery banding in 365 patients who had operations between 1966 and 2001 were reviewed. The patients were divided into three groups: (1) group 1 patients who had operations between 1966 and 1979, (2) group 2 patients who had operations between 1980 and 1989, and (3) group 3 patients who had operations between 1990 and 2001. RESULTS Significantly younger and smaller patients have been operated on recently (mean age: group 1, 169.0 +/- 40 days; group 2, 101.8 +/- 11 days; and group 3, 69.7 +/- 8.9 days; and mean weight: 4.6 +/- 0.1, 4.1 +/- 0.1, and 3.2 +/- 0.1 kg, respectively). A decrease was found in the number of simple cardiac anomalies, such as isolated ventricular septal defects. The early mortality in the three groups was 38.3% for group 1 (65 of 187), 13.5% for group 2 (15 of 111), and 13.8% for group 3 (12 of 87). Although the mortality did not vary significantly between groups 2 and 3, it improved over time in patients weighing less than 3 kg. Multivariate analysis of group 3 demonstrated that no isolated variable, including sex, weight, and diagnosis was a significant risk factor. CONCLUSIONS Despite the advances in perioperative management, we found no improvement in the early mortality of pulmonary artery banding during the last decade. These results will support the preference for primary repair of intracardiac anomalies in small infants. However, this operation can now be performed with the same risk even in smaller patients. We believe that pulmonary artery banding has a role in the treatment of congenital cardiac anomalies.

Abstract
A large load of children with congenital heart disease (CHD) exists in our country. Fortunately facilities for treatment of almost all types of defects are available, although in few centres only. Many children are however, referred late for correction making them either high risk for surgery or inoperable due to development of irreversible pulmonary vascular obstructive disease. Therefore, it is important to recognise the ideal time of intervention in different types of CHD. A child with large atrial septal defect should have its closure by 3 to 4 years of age; on the other hand, a large ventricular septal defect (VSD) producing congestive heart failure needs very early surgery. Infants with small VSD may be medically managed as chances of spontaneous closure are high. Ligation of patent ductus arteriosus should be done at about one year of age if there is no pulmonary arterial hypertension or congestive heart failure. Similarly, coarctation should be dealt with either balloon dilatation or surgery at about one year of age provided the left ventricular function is normal and blood pressure in upper limb is well under control. For tetralogy of Fallot, correction is best done at about 9 months to one year of age. In case the child is symptomatic early, either a palliative shunt is done or total correction is performed if anatomy is suitable. In admixture lesions like transposition of great arteries (TGA), persistent truncus arteriosus or total anomalous pulmonary venous drainage, a very early intervention is needed so as to avoid development of severe hypoxia and early pulmonary vascular obstructive changes. Arterial switch operation is best performed in first two to three weeks of life for TGA with intact ventricular septum cases. Knowledge of natural history of the CHD is essential to plan for optimal timing of surgery or catheter intervention.

Abstract
OBJECTIVE Pulmonary artery banding remains a palliative option for patients with congenital heart disease and excessive pulmonary blood flow, if there is unfavourable anatomy or frail condition. In contrast to more developed countries, our patients at Red Cross Children's Hospital, Cape Town, often present to medical services late and in poor nutritional condition. We retrospectively reviewed patients undergoing pulmonary artery banding to determine major variables that influenced long-term outcome. METHODS In a 10-year period ending June 1992, 135 consecutive patients underwent pulmonary artery banding; 89 with ventricular septal defect type non-mixing disorders, and 46 with mixing or complex disorders. The median age was 3.0 months and weight 3.5 kg with 74.8% of patients weighing less than the third percentile (NCHS adapted), and 39.3% had an additional serious medical illness. RESULTS Pulmonary banding mortality was 8.1%, and was higher in neonates (22.2%), P = 0.04) but was not related to congenital disorder, associated medical illness, or associated coarctation or interrupted aortic arch. The pulmonary band was inadequate at follow-up in 28.9%, which occurred more commonly if banding was necessary before 3 months of age (41.5%, P = 0.003) but was not related to weight, congenital disorder or associated respiratory infection. Sixty patients (44.4%) have now proceeded to definitive repair with a mortality of 23.3%, which was increased if the pulmonary band was inadequate at the time of definitive repair (44.4%: P = 0.02), but was not related to the congenital disorder. CONCLUSIONS An inadequate pulmonary artery band adversely affects outcome and demands further aggressive management prior to definitive repair.

Abstract
Pulmonary artery banding is used in infants to temporarily control excessive pulmonary blood flow. There are reports of band migration including intact bands eroding through the pulmonary artery. The patient presented here had bronchiectasis and eventual destruction of his right middle and lower lobes 5 years after pulmonary artery banding and subsequent definitive cardiac corrective surgery. After undergoing a right middle and lower lobectomy, recurring postoperative respiratory distress prompted repeat bronchoscopy where the original pulmonary artery band was identified and removed. It is hypothesized that this band migrated through the pulmonary artery and into the tracheobronchial tree where it led to obstruction and subsequent destruction of the right middle and lower lobes. Awareness of this potential complication is important for pediatric surgeons who so often care for patients with a past history of cardiac surgery.

Abstract
The objectives of this trial are to assess the safety and effectiveness of the prosthesis and to establish the ability of the dilatable band to provide a nonsurgical option for dilatation. Forty-six patients received dilatable bands. All had congenital heart defects requiring banding of the main pulmonary artery. Dilatation was performed on 7 patients. This was successful in 6 and uncomplicated in all. In one patient the dilatable band was adjusted too tightly at implantation. In one patient the band was adjusted to loosely. In 7 patients the dilatable band was placed too distally and partially obstructed the right or left pulmonary artery. Distal migration of the dilatable band after implantation did not occur. One band was distorted during implantation. This did not compromise its function. Surgical sepsis resulted in a mycotic aneurysm and erosion of the pulmonary artery in one patient. Surgical pulmonary arterioplasty was performed in all 18 patients who had total correction and in 11 of the 13 patients who had bidirectional Glenn procedure and Damus-Stanzell connection. There were 13 deaths. None of the deaths were related to the dilatable band. Thirty-two prostheses were surgically explanted readily and completely in 31 patients. Five bands were removed at postmortem examination. Examination of all 37 of the dilatable bands revealed no evidence of wear or damage. Scanning electron microscopy evaluation was conducted on 5 of the explanted devices which had been implanted 158 to 1139 (mean 422) days. No component failure was identified. The dilatable band prostheses was effective and safe and provided a non-surgical option for dilatation.

Abstract
Pulmonary artery banding is indicated in numerous congenital cardiac defects not amenable to a total repair. One complication of pulmonary artery banding, especially in neonates who require early banding, is progressive cyanosis during the rapid growth phase requiring earlier than anticipated total correction, which may produce a less than optimal result. A simple pulmonary artery band that enlarges as the patient grows would avoid this early complication. We report a technique of pulmonary artery banding in an animal model using different absorbable sutures. The band enlarges in a prescribed staged fashion without any further intervention, hopefully allowing growth of neonates and infants with complex congenital heart disease.

Abstract
A staged surgical approach was developed for the management of hearts with univentricular atrioventricular connection (double-inlet left ventricle or tricuspid atresia) and discordant ventriculoarterial connection with anatomical substrate for the development of subaortic stenosis. This consisted of initial palliation with pulmonary artery banding, followed by early elective relief of subaortic obstruction using a proximal pulmonary artery to ascending aorta anastomosis in infancy. Pulmonary blood flow was maintained at this time by creating a bidirectional superior cavopulmonary anastomosis. Over an 18-month period, 5 children, including 4 seen in the first week of life with aortic arch obstruction, were palliated with this approach. All patients survived operation and are asymptomatic with transcutaneous oxygen saturations of 80% to 85%. Completion of cavopulmonary repair is planned at 2 years of age. Although some authors have considered pulmonary artery banding contraindicated in these infants, the current staged approach offers an attractive alternative to the construction of a pulmonary artery to aorta anastomosis in the neonatal period.

Abstract
Herein, a policy of primary surgical closure of large ventricular septal defects in infants is reviewed. Forty-eight infants met criteria for inclusion in the study, and were divided into two groups based on weight: group 1 infants weighted 4 kg or less (n = 23), and group 2 infants weighed more than 4 kg (n = 25). Both groups had similar variation in ventricular septal defect location (paramembranous versus muscular) and number (single versus multiple), as well as incidence of major associated extracardiac diseases. No early deaths occurred in group 1, compared with 1 infant (4%) in group 2. Major complications occurred similarly in both groups (9% versus 12%). There were two late deaths in group 1 (9%) and none in group 2. No surviving patients have required a second ventricular septal defect operation, and the majority no longer receive anticongestive therapies. These results indicate that primary surgical closure of large ventricular septal defects, even multiple muscular defects, can be performed in very small infants with no difference in mortality or serious complication rates compared with larger infants. Protracted medical efforts to achieve larger size before primary repair and palliative pulmonary artery banding are not necessary.

Abstract
A 25-year experience (May 1962 through April 1987) with pulmonary artery banding in 183 patients was reviewed and analyzed. Pulmonary artery banding was performed in a heterogeneous group of patients aged two days to 60 months (median, 10 weeks; mean, 21.8 weeks) and weighing 1.4 to 13.8 kg (mean, 4.2 kg). Diagnosis was ventricular septal defect in 76 (41.5%) and atrioventricular communis in 41 (22.4%). Pulmonary artery banding was also used in patients with d-transposition of the great vessels with ventricular septal defect, double-outlet right ventricle, univentricular heart, tricuspid atresia, and truncus arteriosus. Early death occurred in 39 of 175 patients who underwent pulmonary artery banding at Ochsner Foundation Hospital (22.3%). Definitive operation has been performed in 37 of the patients who underwent pulmonary artery banding since 1979 with excellent outcome in 32 (86.5%). Pulmonary artery banding is a useful palliative procedure for a diverse group of patients with congenital cardiac anomalies and unrestricted pulmonary blood flow. With improved results of primary repair of intracardiac anomalies in small infants, however, pulmonary artery banding should be reserved for severely ill patients with complex lesions not amenable to early definitive correction. Currently, pulmonary artery banding is indicated in patients with excessive pulmonary blood flow and single ventricle or tricuspid atresia. Pulmonary artery banding is also appropriate in certain patients with atrioventricular communis and in patients with muscular or multiple ventricular septal defects. Pulmonary artery banding is an option in patients with ventricular septal defect and coarctation of the aorta.

Abstract
Balloon dilation was attempted in 16 patients, aged 5 months to 19.5 years, with right ventricular outflow obstruction after repair of congenital heart defects. Stenosis of a valved conduit between the pulmonary ventricle and pulmonary artery was present in nine patients with a mean transvalvular peak systolic ejection gradient of 61.6 +/- 21.0 mm Hg and a mean right ventricle to aorta pressure ratio of 0.9 +/- 0.2. Supravalvular pulmonary stenosis was present in seven patients; in five, stenosis was at the anastomotic site after the arterial switch operation with a mean peak systolic ejection gradient of 72.2 +/- 10.6 mm Hg and mean right ventricle to aorta pressure ratio of 0.93 +/- 0.05. The other two patients had stenosis at a previous pulmonary artery band site with a peak systolic ejection gradient of 60 and 65 mm Hg and right ventricle to aorta pressure ratio of 0.75 and 0.72, respectively. Balloon dilation was successful in three of nine patients with a valved conduit; two of them had additional successful balloon dilation of the right pulmonary artery. In five of the nine patients (including one with successful dilation) the conduit was replaced 5.7 +/- 4.5 months after balloon dilation. Balloon dilation was successful in only one of the five patients with supravalvular pulmonary stenosis after the arterial switch operation and partially successful in the two patients with supravalvular pulmonary stenosis at a previous band site. The success rate of balloon dilation of postoperative right ventricular outflow obstruction is much lower than that for other right heart obstructions.

Abstract
Pulmonary artery (PA) banding to reduce pulmonary blood flow was described by Muller and Dammann in 1952. This review describes the outcome of 170 children who had PA banding at the University of Virginia Medical Center between 1955 and 1988. One hundred and one of the patients were banded between 1958 and 1970; fewer bands were placed in later years because early total correction was feasible for certain conditions. When analyzed by preoperative diagnoses, the data reveal that children with a single ventricle undergoing banding had a significantly lower 30-day mortality rate of 12% compared to other preoperative diagnoses, including atrioventricular canal, truncus arteriosus, and ventricular septal defect (VSD) at 30% (p less than 0.05). The late overall mortality for all patients was approximately 10%, an attrition rate of 1% per year. PA banding still has a role in management of patients with congenital heart disease, particularly for infants with a single ventricle. Actuarial survival at 10 years for patients with this condition is 92%. Interestingly, this indication for pulmonary banding is the same one cited in the original report.
