AbstractThere is little information on the indications for balloon dilation angioplasty for aortic coarctation. To determine the indications for balloon dilation in aortic coarctation, we evaluated prospectively the outcome of children treated according to our therapeutic protocol. The protocol included patients with postoperative recoarctation and isolated native coarctation with risks for surgical repair as conditions for which balloon intervention was absolutely indicated, and native coarctation without a significant arterial duct as a condition possibly qualifying for balloon dilation. Patients with duct-dependent coarctation and diffuse hypoplasia of the aortic arch were not considered to require balloon intervention and were treated surgically. We entered 47 patients into this protocol between January 1988 and December 1993. In 21, dilation was performed successfully and provided significant relief of pressure gradients. The peak systolic pressure gradients across the coarcted site in native coarctation and postoperative recoarctation decreased significantly from 40±19 to 13±10 mm Hg (p<0.0001) and 38±24 to 14±75 mm Hg (p<0.01) immediately after the procedure, respectively. Similarly, the diameters of the coarcted site increased significantly from 3.8±1.8 to 6.6±2.43 mm (p<0.0001) and 4.6±1.9 to 6.0±2.0 mm (p<0.005), respectively. Five patients with native coarctation, and one with postoperative recoarctation, developed restenosis during the period of follow-up and were treated successfully with repeat dilation. It may be possible to change the therapeutic strategy for aortic coarctation with advances in the use of balloon dilation. Our protocol for this technique appears to be reasonable, but further evaluation of its indications is needed.

AbstractObstruction of the reconstructed aortic arch, or the neoaortic arch, is now known to be an important factor increasing mortality after the Norwood operation for hypoplastic left heart syndrome. Transcatheter balloon angioplasty has been shown to provide effective relief of both native aortic coarctation and obstructions of the aortic arch occurring subsequent to therapeutic intervention. We sought to determine the outcomes of balloon angioplasty used as an initial treatment for obstruction of the neoaortic arch occurring after the Norwood operation. We gathered the characteristics of 58 patients with such obstruction from 8 institutions, noting procedural factors and outcomes of initial balloon dilation. Obstruction occurred at a median interval of 4 months, with a range from 1.5 months to 6.3 years, after a Norwood operation. Ventricular dysfunction was present before dilation in 13 patients. Mean peak to peak systolic pressure gradients were acutely reduced from 31±20 mm Hg to 6±9 mmHg (p<0.001), with outcome subjectively judged to be successful in 89%- Three patients with pre-existing ventricular dysfunction died within 48 hours of dilation. There were 10 additional deaths during the period of followup, with Kaplan Meier estimates of survival after intervention of 87% at 1 month, 77% at 12 months, and 72% after 15 months. In addition, 9 patients required re-intervention during the period of follow-up, with Kaplan Meier estimates of freedom from re-intervention after dilation of 87% at 6 months, 78% at 12 months and 74% after 18 months. Although transcatheter dilation of neoaortic arch obstructions after Norwood operation is successful, there is a high risk of re-intervention and ongoing mortality in this subgroup of patients. Close follow-up is recommended.

Abstract Introduction Aneurysms are found following all types of surgical repair of aortic coarctation, especially after Dacron patch aortoplasty. We describe the finding of an aortic aneurysm in an asymptomatic 52-year-old male, who was managed by Dacron patch aortoplasty for native coarctation of the aorta 34 years earlier. Case report A 52-year male, smoker, hypertensive on medication He had previous history of surgical repair of aortic coarctation at age of 18 years . Repair was by Dacron patch aortoplasty. Since then, his regular follow up was unremarkable. Recently, he was referred for cardiac evaluation as a part of pre-employment general check-up. He was asymptomatic with no history of shortness of breath or chest pain. Physical examination revealed that the pulse in the left arm was reduced in volume in comparison to the right one. The heart sounds were essentially normal but a pericardial murmur was audible, perhaps reflecting residual collateral flow. Blood pressure was 156/83 mmHg in right arm and 142/81 in the left arm. Transthoracic echocardiography revealed mild left ventricular hypertrophy with normal global and regional contractility and an ejection fraction of 58%. Supra sternal window images showed dilatation of the three aortic arch branches. The distal portion of aortic arch just distal to origin of left subclavian artery was narrowed with a peak systolic gradient across of 34 mmHg. A cystic structure (1.7 cm x 1.9 cm) was visualized attached to the narrowed segment of the aorta, suggestive of a saccular aneurysm, (figures A&B&C). Computed tomography aortogram showed a narrow-necked aneurysm arising from the posterolateral aspect of the distal aortic arch (anticipated site of the coarctation repair graft anastomosis). A small laminated thrombus was also noted within. Aneurysm measured approximately 2.2 x 3.3 cm in its craniocaudal and anteroposterior dimensions respectively, with no evidence of aortic luminal compromise. (figures D&E&F). Management Aneurysmectomy was performed subsequently. Interposition polyester grafts were used to reconstruct the aortic arch and proximal descending aorta and to connect this aortic segment to the subclavian artery via a lateral thoracotomy. The postoperative course thereafter was uneventful. Conclusion: This is a rare insidious complication of Dacron patch aortoplasty that occurred after more than 3 decades, which highlights the importance of diagnostic imaging in the follow up of these patients Abstract P1494 Figure.

AbstractTo evaluate early and long-term results of surgical treatment of aortic coarctation (CoAo) in neonates. This is a retrospective clinical review of neonates with CoAo, who underwent surgery between 1995 and 2019. Data were retrieved from our institutional database, to identify preoperative and postoperative characteristics. Statistical analysis was performed by means of relative risk ratio and Cox and logistic multivariate analysis. 218 consecutive neonates (M/F: 129/89, median age 11 days, IQR 7–17 days) were included; 202 (92.7%) had a left thoracotomy; 178 underwent extended end-to-end anastomosis (EEEA, 81.6%). Hypoplastic aortic arch (HAA) was present in 102 patients (46.8%); complex cardiac anomalies in 85 (39%). Significant postoperative complications occurred in 20 (9.2%). Thirty-day mortality was 2.3% (most in complex types). At a median follow-up of 10.4 years (IQR 5.6–15.0 years; FU completeness 95.9%), there were 8 late deaths (3.7%), all associated to complex CoAo. Among 196 survivors, 177 (93.2%) were in NYHA class I; re-interventions on aortic arch occurred in 9.2% (2.0% were surgical). Freedom from mortality and re-intervention on aorta at 10 years were 94.3% and 96.7%, respectively. Surgical repair of CoAo in newborns without CPB in our series was safe and low-risk, with excellent early and late outcomes.

Main Challenge

AbstractOBJECTIVESThe main challenge of aortic coarctation (CoA) repair in infants is to obtain durable results without morbidity. We aimed to describe predictors of aortic arch reintervention after aortic CoA repair.METHODSBetween January 2000 and March 2014, we retrospectively included consecutive infants with isolated CoA or CoA with ventricular septal defect (CoA + VSD) who had surgical repair of the aortic arch before 3 months of age.RESULTSFive hundred and thirty patients were included: 308 (58%) patients had isolated CoA and 222 (42%) patients had CoA + VSD. Three hundred and eighty-five patients (72.6%) had CoA repair, 51 patients (9.6%) had CoA repair with closure of VSD and 94 patients (17.8%) had CoA repair with pulmonary artery banding. Mean age at operation was 13 ± 1.6 days, with 294 patients (55.5%) operated on before 2 weeks. Median follow-up was 7.57 years. Sixty-one patients (11.5%) needed reintervention on the aortic arch. Freedom from aortic arch reintervention was 90% at 1 year and 88.5% at 5 years. Proportions of aortic arch reintervention were similar in the different surgical strategy groups (P = 0.80). However, in patients receiving prostaglandin E1 (PGE1), the end-to-end repair was at higher risk of recoarctation compared to the extended end-to-side repair (P = 0.033). The risk factors of aortic arch reintervention were age at repair <15 days (P = 0.034) and the need for PGE1 infusion at surgery (P = 0.0043).CONCLUSIONSCoA repair in young infants has an overall good outcome. The use of PGE1 may modify the aortic arch anatomy and mask the boundaries of the resection to be performed. PGE1 treatment should be studied more specifically in another study to improve preoperative management.

We inserted covered Cheatham-Platinum stents in 4 patients, ranging in age from 12 to 19 years, who weighed between 45 and 94 kg. All the patients had aortic coarctation, with surgical repair having been attempted previously in one, and with balloon dilation having been performed as the primary treatment in two, resulting in formation of aneurysms. The fourth patient had not received any treatment. The gradients were reduced from 10 to 40 mmHg before insertion of the stent to 0 to 5 mmHg after stenting. No complications were encountered. All the patients are well at an interval of 3 to 14 months after stenting.

Aortic Arch Hypoplasia

Abstract Background Despite a successful repair procedure for coarctation of the aorta (CoA), up to two-thirds of patients remain hypertensive. CoA is often seen in combination with abnormal aortic arch anatomy and morphology. This might be a substrate for persistent hypertension. Therefore, we performed endovascular aortic arch stent placement in patients with CoA and concomitant aortic arch hypoplasia or gothic arch morphology. The goal of this retrospective analysis was to investigate the safety and efficacy of aortic arch stenting. Methods A retrospective analysis was performed in patients who underwent stenting of the aortic arch at the University Medical Center Utrecht. Measurements collected included office blood pressure, use of antihypertensive medication, invasive peak-to-peak systolic pressure over the arch, and aortic diameters on three-dimensional angiography. Data on follow-up were obtained at the date of most recent outpatient visit. Results Twelve patients underwent stenting of the aortic arch. Mean follow-up duration was 14 ± 11 months. Mean peak-to-peak gradient across the arch decreased from 39 ± 13 mm Hg to 7 ± 8 mm Hg directly after stenting (p < 0.001). There were no major procedural complications. Mean systolic blood pressure decreased from 145 ± 16 mm Hg at baseline to 128 ± 9 mm Hg at latest follow-up (p = 0.014). Conclusion This retrospective study shows that stenting of the aortic arch is successful when carried out in a state-of-the-art manner. A direct optimal angiographic and haemodynamic result was shown. No major complications occurred during or after the procedure. At short- to medium-term follow-up a decrease in mean systolic blood pressure was observed.

Background: This is a review of the experience over 26 year in a single institution with surgical repair of aortopulmonary window. Methods: Between July 1973 and March 1999, 38 patients underwent surgery for aortopulmonary window at a median age of 5 weeks, and with a median weight of 3.9 kg. Median follow-up was 6.6 years, with a range from 0.8 to 26 years. Additional defects were present in 25 (65%) patients, including interruption of the aortic arch in 7, tetralogy of Fallot in 7, ventricular septal defect in 5, functionally univentricular anatomy in 3, aortic coarctation in 2, and anomalous origin of a coronary artery in 1. We approached via an aortotomy in 45%, an incision through the defect in 31%, and using a pulmonary arteriotomy in 24% of patients. Closure was achieved using a single patch in 30 patients (79%). Results: There were 3 (7.9%) in-hospital deaths. Actuarial patient survival was 88% at 10 years. Three patients required reinterventions for stenoses of the great arteries. Freedom from any reintervention was 70% at 10 years. By multivariate analysis, the approach through a pulmonary arteriotomy was shown to result in a higher need for reintervention (p = 0.01). Conclusions: Repair of aortopulmonary window can be done with excellent results. A pulmonary arteriotomy should be avoided.
