Abstract
Balloon angioplasty for native coarctation of the aorta in infants and children is gaining acceptance as an alternative to surgery in discrete membranous obstruction. The aim of this study was to assess the immediate and intermediate-term effectiveness and safety of balloon angioplasty in infants and children with discrete membranous obstruction and mild complex arch anomalies. We performed a retrospective study evaluating the immediate and intermediate-term results of balloon angioplasty in 46 consecutive patients with native coarctation of the aorta done between March 1998 and June 2003. Isolated discrete fibromembranous obstruction occurred in 32 patients, and 14 patients had mild complex arch anomalies. Follow-up was obtained in 40 patients. There was no early mortality. The procedure was initially successful in 43 patients (93%). There were three immediate failures. Of the 40 patients who were followed, 32 (80%) had maintained a cuff pressure gradient of 20 mmHg across the dilated area. Four patients developed restenosis, which was successfully treated by repeated balloon angioplasty. The other four patients continued to have mild gradient (20-22 mmHg) with systolic hypertension and without angiographic evidence of restenosis but with isthmus hypoplasia; they received atenolol and captopril. Serial echocardiographic measurement of left ventricular dimension and function revealed significant improvement after balloon angioplasty of aortic coarctation in patients with the echocardiographic picture of hypertensive cardiomyopathy. Balloon angioplasty may be considered as a tool in the armamentarium of management of aortic coarctation in different anatomic variants, taking into consideration the clinical presentation and patient age.

Abstract
Management of native aortic coarctation during early months of life poses therapeutic challenges, and there is no consensus among medical professionals regarding a management plan. Much can be argued about the benefits, limitations, and/or complications of transcatheter versus surgical intervention in such cases. Occasionally, the complexity of the lesions limits management options. Therefore, each patient requires individual management decisions because there is no one therapeutic plan that satisfies all patients. In this report, four critically ill infants who had complex native coarctation are presented. Surgical repair was not possible because of relative contraindications. The patients underwent transcatheter stent implantation (six procedures and seven stents) as a nondefinitive procedure with acceptable results. Three patients improved. One patient did not survive, mainly due to other major complications. Multiple reexpansions of the stents were carried out when indicated. After a mean follow-up of 45 months (range, 41-49), the three survivors were doing fine and had gained an average weight of 9.7 kg (range, 6.6-13.3). At the time of reporting, the relative contraindications no longer exist and the final surgical repair can be carried out. Our experience suggests that in certain situations and in critically ill infants with complex form of coarctation, stent angioplasty can be used as a life-saving palliative procedure. Further reexpansions can be done when required. This may serve as a bridge to major surgical repair in the future.

Abstract
BACKGROUND Little is known regarding the long-term follow-up results of balloon angioplasty (BA) for patients with aortic coarctation (AC) on systemic hypertension. HYPOTHESIS To define the long-term effect of BA of AC on systemic hypertension in adolescent and adult patients. METHODS Follow-up data of 53 patients (36 male), mean age 24 +/- 9 years, undergoing BA for discrete AC at median interval of 11.8 years (range, 4-18 years), including cardiac catheterization, magnetic resonance imaging (MRI), and echocardiography. Patients were divided into two groups at 1 year after BA on the basis of absence (group A: 40 patients) or presence (group B: 11 patients) of persistent hypertension and need for medication. RESULTS Fifty-one patients had baseline hypertension, BA produced an immediate reduction in peak AC gradient from 66 +/- 23 mmHg to 10.8 +/- 7 mmHg (p < 0.0001). The immediate systolic blood pressure (SBP) decreased from 165 +/- 17 mmHg (95% CI: 159 to 171) to 125 +/- 10 mmHg (95% CI: 122 to 131) (p < 0.001) in 40 patients (group A) and from 184 +/- 19 mmHg (95% CI: 169 to 198) to 142 +/- 22 mmHg (95% CI: 124 to 156) (p<0.001) in 11 patients (group B). At 1-year follow-up, SBP decreased further to 115 +/- 10 in group A (95% CI 111-119) and 134 +/- 19 in group B (95% CI 122-142) (p<0.001). The blood pressure had normalized without medication in group A (165 +/- 17 to 115 +/- 10 mmHg). CONCLUSION Long-term results of BA for discrete AC are excellent and should be considered as the first option for treatment of this disease. No paradoxical hypertension occurred post angioplasty, and normalization of blood pressure without medication occurred in 78% of the patients after BA.

Abstract
Coarctation of the aorta is an important, treatable cause of secondary hypertension. Its prevalence varies from 5% to 8% of all congenital heart defects. This condition is most often detected because of a murmur or hypertension found on routine examination. Delayed or absent femoral pulses and an arm/leg systolic blood pressure difference of 20 mm Hg or more in favor of the arms may be considered as evidence for aortic coarctation. The coarctation may be demonstrated on a suprasternal notch two-dimensional echocardiographic view along with increased Doppler flow velocities across the coarctation site. Cardiac catheterization reveals significant systolic pressure gradient (> 20 mm Hg) across the coarctation and angiography demonstrates the degree and type of aortic narrowing. Aortic obstruction may be relieved by surgery or by transcatheter techniques; the latter include balloon angioplasty and stent implantation. In the past, surgery has been used exclusively, but because of morbidity and complications associated with surgery, catheter techniques are increasingly used in the management of aortic coarctation. Balloon angioplasty in children and stents in adolescents and adults are becoming initial therapeutic options for management of coarctation. Studies evaluating long-term follow-up results of the interventional techniques are needed.

Abstract
OBJECTIVES This study evaluated the long-term follow-up results of balloon angioplasty (BA) in adolescent and adult patients with discrete coarctation of the aorta. BACKGROUND Although the immediate and intermediate term results of BA for patients with aortic coarctation (AC) have been encouraging, there is a paucity of data on long-term follow-up results. METHODS This basis of this study was follow-up of 49 patients (mean age, 22 +/- 7 years) undergoing BA for discrete AC at median interval of 10.2 years, including cardiac catheterization, magnetic resonance imaging, and Doppler echocardiography. RESULTS No early or late deaths occurred. Balloon angioplasty produced a reduction in peak AC gradient from 66 +/- 23 mm Hg (95% confidence interval [CI]: 59.5 to 72.7) to 10.8 +/- 7 mm Hg (95% CI: 8.8 to 12.5) (p < 0.0001). Follow-up catheterization 12 months later revealed a residual gradient of 6.2 +/- 6 mm Hg (95% CI: 4.4 to 7.9) (p < 0.001). Four patients (7.5%) with suboptimal initial outcome with peak gradient >20 mm Hg had successful repeat angioplasty. Aneurysm developed at the site of dilation in four patients (7.5%). Magnetic resonance imaging follow-up results revealed no new aneurysm or appreciable changes in the size of pre-existing aneurysms, and no recoarctation was observed. Also, no appreciable changes in the Doppler gradient across the AC site were noted. The blood pressure had normalized without medication in 31 (63%) of the 49 patients. CONCLUSIONS Long-term results of BA for discrete AC are excellent and should be considered as first option for treatment of this disease.

Abstract
Although immediate and intermediate-term results after balloon dilatation of congenital stenotic lesions of the heart in children are well studied, long-term results have not been documented. Therefore, we reviewed our experience along with the limited published data to address this issue. Late follow-up after balloon pulmonary and aortic valvuloplasty shows low-residual gradients, reintervention-free rates in the mid-80s for pulmonic and in the mid-50s for aortic stenosis, and an increase in degree and prevalence of similunar valve insufficiency. Balloon angioplasty of aortic coarctation results in low-residual gradients, residual hypertension in a minority of patients, low prevalence of aneurysms, and high rates of recurrence in the neonate and young infant. Overall, balloon dilatation is a useful technique in relieving congenital obstructive lesions of the heart in the pediatric patient, but continued study of (1) late pulmonary and aortic insufficiency after valvuloplasty, (2) recurrence and aneurysms after balloon angioplasty of coarctations and, (3) femoral artery compromise in lesions requiring transfemoral artery approach is warranted.

Abstract
OBJECTIVES We attempted to evaluate the role of balloon angioplasty in the treatment of discrete coarctation of the aorta in adolescents and adults, with special emphasis on long-term results. BACKGROUND Controversy persists over the use of balloon dilation for the treatment of native coarctation of the aorta. METHODS Between July 1986 and January 1997, 43 consecutive adolescent and adult patients with discrete coarctation of the aorta underwent balloon angioplasty. One- to 10-year follow-up data of 37 patients, including results of cardiac catheterization and magnetic resonance imaging (MRI), form the basis of this study. RESULTS No early or late deaths occurred. Balloon angioplasty produced a reduction in the peak to peak coarctation gradient from a mean +/- SD of 69 +/- 24 mm Hg (95% confidence interval [CI] 61 to 76) to 12 +/- 8 mm Hg (95% CI 10 to 14.8) (p < 0.001). Follow-up catheterization 12 months later (37 patients) revealed a residual gradient of 6.7 +/- 6 mm Hg (95% CI 4.6 to 8.9); 3 (7%) of 43 patients had suboptimal results with development of recoarctation, defined as peak gradient >20 mm Hg, with successful repeat angioplasty. A small aneurysm developed at the site of dilation in 3 (7%) of the 43 patients. MRI follow-up data 1 to 10.8 years (mean 5.2 +/- 2.7) after angioplasty (37 patients) revealed no new aneurysm or appreciable change in the size of the preexisting aneurysm in the three patients. The blood pressure had normalized without medication in 27 (73%) of 37 patients at follow-up examination. CONCLUSIONS Balloon angioplasty is safe and effective and should be considered a viable alternative to operation for treatment of discrete coarctation of the aorta in adolescents and adults.

Abstract
The use of balloon dilation to treat native aortic coarctation is controversial, particularly in infants. Between January 1991 and September 1996, 12 patients < or = 3 months of age with native coarctation of the aorta (CoA) underwent balloon angioplasty (BA). All 12 lesions were dilated successfully with a mean reduction in peak systolic gradient from 49.3 +/- 16.5 mm Hg to 6.8 +/- 4.0 mm Hg (p < 0.001) and a mean increase in minimum CoA diameter from 2.4 +/- 0.6 mm to 5.5 +/- 1.3 mm (p < 0.001). Intimal flaps or tears were detected immediately after BA in 4 (33%) of 12 patients by angiography and in 8 (89%) of 9 patients by intravascular ultrasonography. No deaths or major complications related to the BA occurred. One patient had documented asymptomatic femoral artery obstruction, and one patient with hydrops fetalis and congenital pleural effusions died with gram-negative sepsis 1 week after the procedure. Follow-up was available for 10 patients (1 was lost to follow-up) between 2 months and 4.1 years (mean 2.4 +/- 1.3 years) after BA. No patient had an aortic aneurysm. Restenosis occurred in 5 (50%) of 10 patients, requiring reintervention a mean of 2.6 +/- 2.1 months after BA. One patient underwent surgical repair. Repeat BAs were performed in the other four patients; three were successful, and one with partial gradient relief required surgical repair. Five patients have not required reintervention a mean of 2.9 +/- 1.0 years after the initial BA. Among these five patients, follow-up intravascular ultrasound performed in three patients a mean of 2.0 +/- 1.9 years after BA showed favorable endovascular remodeling. There was a tendency for early reintervention in patients < 1 month of age and coexistence of a patent ductus arteriosus at the time of BA. In conclusion, selected infants < or = 3 months of age with discrete native CoA may be treated initially with balloon dilation. Most patients who have restenosis respond successfully to repeat BA.

Abstract
OBJECTIVES This study sought to compare the immediate results and risk factors for suboptimal outcomes of percutaneous balloon angioplasty for native versus recurrent aortic obstruction. BACKGROUND Some cardiology centers have been reluctant to adopt balloon angioplasty for treatment of native aortic coarctation, while advocating balloon angioplasty over an operation for treatment of postsurgical or recurrent aortic obstruction. METHODS Acute results were analyzed from 970 procedures (422 native and 548 recurrent lesions) performed between 1982 and 1995 in 907 patients from 25 centers. An acute suboptimal outcome was defined as one or more of the following: residual systolic pressure gradient > or = 20 mm Hg, residual proximal to distal systolic pressure ration > or = 1.33 or a major complication (death, aortic transmural tear, stroke). RESULTS Bal loon angioplasty significantly (p = 0.0001) increased lesion diameter fo r both native (mean [+/= SD] 128 +/= 94%) and recurrent aortic obstruction (97 +/= 87%), with a significantly greater increase in the native group (p = 0.0001). A reduction in systolic pressure gradients was significant in both groups (p = 0.0001), but slightly higher (p = 0.01) for native (-74 +/- 24%) versus recurrent obstruction (-70 +/- 31%). Death associated with angioplasty was reported in 0.7% of patients with native and in 0.7% of patients with recurrent lesions (p = 1.00). An acute suboptimal outcome was noted with angioplasty in 19% of native and in 25% of recurrent lesions (p = 0.04). Significant independent risk factors included higher preangioplasty systolic gradient (odds ratio [OR] 1.39/10-mm Hg increment; 95% confidence interval [CI] 1.28 to 1.50, p = 0.0001), earlier study date (OR 0.92/1-year increment, 95% CI 1.02 to 1.26, p = 0.02) and recurrent obstruction (OR 1.39 vs. native lesions, 95% CI 1.00 to 1.94, p = 0.05). CONCLUSIONS Acute results and complications of balloon angioplasty of native coarctation appear to be equivalent or slightly superior to those of recurrent aortic obstructions.

Abstract
We report two infants each with coarctation of the aorta and small patent ductus arteriosus who had balloon angioplasty therapy for aortic obstruction at 3-6 months of age followed by anterograde placement of a single Gianturco coil to close the ductus at a separate catheterization. One infant developed recoarctation that resolved with repeat angioplasty prior to closure of the ductus. Follow-up evaluations have demonstrated a trivial aortic gradient, no aortic aneurysm, and no residual shunt.

Abstract
OBJECTIVES To evaluate the usefulness of balloon angioplasty for relief of native aortic coarctation, we reviewed our experience with this procedure, with special emphasis on follow-up results. BACKGROUND Controversy exists with regard to the role of balloon angioplasty in the treatment of native aortic coarctation. METHODS During an 8.7-year period ending September 1993, 67 neonates, infants and children underwent balloon angioplasty for native aortic coarctation. A retrospective review of this experience with emphasis on long-term follow-up forms the basis of this study. RESULTS Balloon angioplasty produced a reduction in the peak-to-peak coarctation gradient from 46 +/- 17 (mean +/- SD) to 11 +/- 9 mm Hg (p < 0.001). No patient required immediate surgical intervention. At intermediate-term follow-up (14 +/- 11 months), catheterization (58 patients) and blood pressure (2 patients) data revealed a residual gradient of 16 +/- 15 mm Hg (p > 0.1). When individual results were scrutinized, 15 (25%) of 60 had recoarctation, defined as peak gradient > 20 mm Hg. Recoarctation was higher (p < 0.01) in neonates (5 [83%] of 6) and infants (7 [39%] of 18) than in children (3 [8%] of 36), respectively. Two infants in our early experience had surgical resection with excellent results. Three patients had no discrete narrowing but had normal arm blood pressure and had no intervention. The remaining 10 patients had repeat balloon angioplasty with reduction in peak gradient from 52 +/- 13 to 9 +/= 8 mm Hg (p < 0.001). Reexamination 31 +/- 18 months after repeat angioplasty revealed a residual gradient of 3 to 19 mm Hg (mean 11 +/- 6). Three (5%) of 58 patients who underwent follow-up angiography developed an aneurysm. Detailed evaluation of the femoral artery performed in 51 (88%) of 58 patients at follow-up catheterization revealed patency of the femoral artery in 44 (86%) of 51 patients. Femoral artery occlusion, complete in three (6%) and partial in four (8%), was observed, but all had excellent collateral flow. Blood pressure, echocardiography-Doppler ultrasound and repeat angiographic or magnetic resonance imaging data 5 to 9 years after angioplasty revealed no new aneurysms and minimal (2%) late recoarctation. CONCLUSIONS On the basis of these data, it is concluded that balloon angioplasty is safe and effective in the treatment of native aortic coarctation; significant incidence of recoarctation is seen in neonates and infants; repeat balloon angioplasty for recoarctation is feasible and effective; and the time has come to consider balloon angioplasty as a therapeutic procedure of choice for the treatment of native aortic coarctation.

Abstract
In patients with coarctation of the aorta arterial hypertension frequently persists when surgical repair is performed after age 20 years. There are little data on the long-term effect of angioplasty and the question remains to be determined whether hypertension is sufficiently treated by this procedure. Twenty-nine consecutive patients (9 females and 20 males) 14 to 54 years old (median, 25) underwent angioplasty for native coarctation of the aorta. Twenty-five patients (86%) had pre-existing systolic arterial hypertension (> 140 mm Hg). The mean peak systolic pressure gradient decreased from 62 +/- 18 to 21 +/- 13 mm Hg immediately after angioplasty. At hospital discharge 13 patients still had hypertension. After a mean follow-up interval of 4.0 years (range, 0.3-9.5) the residual peak pressure gradient was 14 +/- 13 mm Hg. Blood pressure was normal without antihypertensive therapy in 23 patients (79%). In the six hypertensive patients the pressure gradients were 7, 13, 30, 30, 35, and 60 mm Hg. One patient died 8 months after angioplasty and another underwent surgery for aortic aneurysm. Although this was an uncontrolled study the data suggest that normalization of blood pressure may occur more frequently after angioplasty than after surgery in adolescents and adults with native coarctation.

Abstract
Balloon angioplasty of native coarctations of the aorta is one of the most controversial facets of the pediatric interventional cardiologist's practice. We have evaluated the history and experimental rationale of this technology. Presently accepted techniques are outlined and controversies intrinsic in performance of this procedure are discussed. Acute, short-term, and long-term results are reviewed with particular emphasis on differences in success of the procedure as related to patient age. Common and significant complications are discussed and in some cases compared to analogous surgical complications. Newer technologies and approaches to interventional therapy for coarctation of the aorta are also discussed.

Abstract
Despite gratifying immediate results, significant recoarctation at follow-up has been observed after balloon angioplasty of native aortic coarctation. Risk factors for such recurrences have been identified in one of our previous studies. In this study we examined the value of these risk factors in the prediction of recoarctation after balloon angioplasty. During a 6-year period ending in September 1993, 37 infants and children aged 2 days to 15 years underwent balloon angioplasty of native coarctation with resultant reduction in coarctation gradient from 45 +/- 17 (mean +/- SD) to 12 +/- 9 mm Hg (p < 0.001). On the basis of results of 4- to 48-month follow-up catheterization in 30 children, recoarctation developed in 8 (27%) children. The data from these patients were scrutinized to identify subjects that exhibited the previously determined risk factors, namely age < 12 months, size of aortic isthmus less than two thirds the size of the ascending aorta, coarcted aortic segment < 3.5 mm before angioplasty, and coarcted segment < 6.0 mm after angioplasty. Then, thirty variables (Table I) were examined by logistic regression to identify factors responsible for recoarctation; the data from both study groups were combined for this analysis. The prevalence of recoarctation in each subgroup with a given number of risk factors is similar (p < 0.1) to that observed in the initial study identifying the risk factors. In addition, logistic regression identified age (p = 0.014), size of isthmus (p = 0.006), preangioplasty coarcted segment (p = 0.01), and postangioplasty coarcted segment (p = 0.006) as risk factors.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Between May 1984 and April 1993, 59 children underwent balloon angioplasty of a native coarctation at our institution. The follow-up protocol included a cardiac catheterization 1 to 2 years after angioplasty, which was performed in 90% of patients with > or = 2 years follow-up. Angioplasty caused an acute decrease in peak systolic gradient from 46 +/- 2 to 15 +/- 2 mm Hg, without early aneurysm or emergent surgical intervention in any patient. Based on follow-up data, a satisfactory result was obtained in 38 patients (64%; 70% confidence limit: 58% to 71%), defined as a residual systolic gradient < 20 mm Hg and no aneurysm. In these patients the gradient decreased acutely from 43 +/- 2 to 9 +/- 1 mm Hg, was 6 +/- 1 mm Hg at follow-up catheterization, and 9 +/- 2 mm Hg by clinical evaluation 4.4 +/- 0.3 years after angioplasty. Twenty-one patients (36%; 70% confidence limit: 29% to 42%) had an unsatisfactory result due to a residual gradient > or = 20 mm Hg (n = 19) or aneurysm formation (n = 3), or both. Restenosis occurred in 6 patients, and occurred more in infants than in children > or = 12 months of age (3 of 5 infants vs 3 of 41 children, p = 0.01). Thus, balloon angioplasty provides an effective initial treatment strategy for native coarctation in most children aged > 12 months.
