Abstract
Abstract Objective The objective of this study was to evaluate outcomes of endovascular treatment of aortic coarctation in adults. Methods Clinical data and imaging studies of 93 consecutive patients treated at nine institutions from 1999 to 2015 were reviewed. We included newly diagnosed aortic coarctation (NCO), recurrent coarctation, and aneurysmal/pseudoaneurysmal degeneration (ANE) after prior open surgical repair (OSR) of coarctation. Primary end points were morbidity and mortality. Secondary end points were stent patency and freedom from reintervention. Results There were 54 (58%) male and 39 (42%) female patients with a mean age of 44 ± 17 years. Thirty-two patients had NCO (mean age, 48 ± 16 years) and 61 had endovascular reinterventions after prior OSR during childhood (mean, 30 ± 17 years after initial repair), including 50 patients (54%) with recurrent coarctation and 11 (12%) with ANE. Clinical presentation included asymptomatic in 31 patients (33%), difficult to control hypertension in 42 (45%), and lower extremity claudication in 20 (22%). Endovascular treatment was performed using balloon-expandable covered stents in 47 (51%) patients, stent grafts in 36 (39%) patients, balloon-expandable uncovered stents in 9 (10%) patients, and primary angioplasty in 1 (1%) patient. Mean lesion length and diameter were 64.5 ± 50.6 mm and 19.5 ± 6.7 mm, respectively. Mean systolic pressure gradient decreased from 24.0 ± 17.5 mm Hg to 4.4 ± 7.4 mm Hg after treatment (P  Conclusions Endovascular repair is effective with an acceptable safety profile in the treatment of NCO and postsurgical complications of coarctation after initial OSR. Aortic rupture is an infrequent (2%) but devastating complication with high mortality. Balloon-expandable covered stents are preferred for NCO, whereas stent grafts are used for ANE. The rate of reinterventions is acceptable, with high procedural and long-term clinical success.

Background—The Coarctation of the Aorta Stent Trial (COAST) was designed to assess the safety and efficacy of the Cheatham Platinum stent when used in children and adults with native or recurrent coarctation. Acute outcomes have been reported. We report here follow-up to 2 years. Methods and Results—A total of 105 patients underwent attempted implantation, with 104 successes. There were no procedural deaths, serious adverse events, or surgical intervention. All patients experienced immediate red...

The incidence of spinal cord injury in thoracic endovascular aortic repair (TEVAR) has been 3–5 % from recent major papers where sacrifice of the critical intercostal arteries is inevitable by a stent graft. Hemodynamic stability, which depends on a network of blood vessels around the cord is most important not only during but also after stent-graft deployment. High risk factors of spinal cord injury during endovascular aortic repair are (1) coverage of the left subclavian artery, (2) extensive ...

Background In some patients, local surgery-related complications are diagnosed many years after surgery for aortic coarctation. The purposes of this study were: (1) to systematically evaluate asymptomatic adults after Dacron patch repair in childhood, (2) to estimate the formation rate of secondary thoracic aortic aneurysms (TAAs) and (3) to assess outcomes after intravascular treatment for TAAs. Methods This study involved 37 asymptomatic patients (26 female and 11 male) who underwent surgical ...

Background Surgical repair of aortic coarctation has been performed at the Mayo Clinic, Rochester, Minnesota, for over 60 years. Methods Between 1946 and 2005, 819 patients with isolated coarctation of the aorta underwent primary operative repair. Medical records were reviewed and questionnaires mailed to the patients. Results Mean age at repair was 17.2 ± 13.6...

Background Open, hybrid, and endovascular procedures are used for grown-up patients with aortic coarctation and complications after repair, an expanding population. We sought to characterize patients and procedures, assess early and late outcomes, and describe indications to guide treatment of these complex patients. Methods Between May 1999 and January 2011, 110 patients underwent open (n = 40), hybrid (n = 11), or endovascular (n = 59) repair of coarctation (n = 43), recurrent aortic coarctati...

Ascending aorta and aortic arch replacement combined with antegrade stent grafting of the descending thoracic aorta represents an emerging hybrid surgical approach for complex and extensive thoracic aortic disease. We present a case of a patient at low risk for spinal cord ischemia who underwent hybrid thoracic aortic surgery (aortic arch replacement and E-vita prosthesis implantation) and developed a spinal cord injury (SCI) after the intervention. Treatment aimed at increasing spinal cord perf...

In this report, we describe a technique that could potentially be used for both prevention and treatment of spinal cord ischemia (SCI) in endovascular repair of thoracoabdominal aneurysms. This technique involves using a specially designed endograft with side branches (paraplegia prevention branches [PPBs]), which are left patent to perfuse the aneurysmal sac and any associated lumbar or intercostal arteries in the early postoperative period. The use of PPBs with this technique is feasible and a...

Background We analyzed the potential of endovascular stent grafts to treat late aortic pseudoaneurysms after coarctation repair. Methods Eight patients (7 male; age 28 to 58, mean 43 years) presented with aortic pseudoaneurysms after primary repair performed at the age of 5 to 27 (mean 12) years; 2 patients had rupture with hemorrhagic shock. The mean interval between the procedures was 31 (19 to 42) years; one patient had 3 previous operations. This subset represents 2.2% of our overall experie...

OBJECTIVES Although endovascular repair has become an alternative treatment for coarctation of the aorta (CoA) in adults, open repair provides concomitant repair of other cardiac complications, including post-stenotic aneurysm, ascending aortic aneurysm, and intracardiac diseases. We evaluated open anatomical repair for CoA repair in adults. METHODS Eleven patients (6 men, age range 21-63 years) underwent primary CoA repair. Complicating conditions included post-stenotic aortic aneurysm in the d...

A 79-year-old man developed bilateral intermittent claudication. Peritoneal dialysis had been initiated at 55 years of age to manage chronic renal failure. In addition, he underwent kidney transplantation at 61 years of age. His Ankle-Brachial Index (ABI) was 0.82 and 0.71 for the right leg and left leg, respectively. Furthermore, his serum creatinine level had increased from 0.98 mg/dL to 2.38 mg/dL over the past 2 years. CT angiography revealed focal calcified stenosis in the terminal abdomina...

Acute occlusion of the descending thoracic aorta (DTA) is rare and associated with high morbidity and mortality. In the case described here, rescue thoracic endovascular aortic repair (TEVAR) was successful in a 59-year-old man with acute occlusion of the DTA accompanied by lower body hypoperfusion after two previous open repairs for aortic coarctation.

Abstract Background In our study, we sought to analyse the mid-term results after interventional aortic coarctation (CoA) stenting with sequential dilation of the stent. Methods The data of all 218 patients, who are above the age of 6 years and underwent CoA-stent implantation in our hospital, were retrospectively analysed on the rate of re-interventions, complications and arterial hypertension at a follow-up time of 31 months. To avoid any aortic complications, stents were deployed primarily no...

We herein report a case of a 20-year-old man with aortic regurgitation (AR), coarctation of the aorta (CoA), and patent ductus arteriosus (PDA). The preoperative ankle-brachial pressure index was 0.56 in bilateral extremities. Enhanced computed tomography revealed CoA-postductal type. We decided to perform a two-stage surgery: thoracic endovascular aortic repair (TEVAR) for CoA and PDA and then open surgery for AR. TEVAR was successfully performed with deployment of the stent graft at a 31-mm di...

We present a unique case of late diagnosis of coarctation of the aorta in an adult, presenting with congestive heart failure associated with severe aortic and mitral valve insufficiency. To minimize operative risk, staged endovascular repair of the coarctation was initially performed, followed by aortic valve replacement and mitral valve repair. Six months postoperatively, the 41-year-old patient remains completely asymptomatic.
