“…The result of this study is in contrast with the results presented by Chessa et al [7] and Alcibar et al [8]. In our group of patients, similarly to others [6,[9][10][11], no deaths were observed during or after SI. Data of surgical treatment of aortic coarctation are confounded because of heterogeneous subject population, incomplete follow-up, and frequently unclear distinctions between planned and unplanned intervention.…”

“…According to the published data of Meadows et al [11], CP stent fractures were noted in two patients after one year, and in 11 patients after two years (among 104 treated), with evidence of fracture progression. From our experience (presented elsewhere [6]) we observed no fractures in any of the 48 Andrastents XL and XXL that we used to dilate native coarctation of the aorta and ReCoA.…”

“…In one case of a 10-year-old girl with a body weight of 27 kg, a self-expanding stent (Smart) was applied (patient 6, Table 1). Characteristics of those stents and details of stent implantation are described elsewhere [2,5,6]. Palmaz stents are made of steel with sharp ends, while CP, CVCP, and AS are round-ended and composed of gold and platinum as CP/CVCP, or cobalt and chrome alloy as AS.…”

Endovascular stenting of ReCoA in adults and adolescents appears to be an acceptable method of treatment in experienced hands. However, for some patients the presence of a stiff lesion can provoke suboptimal results. Considering the serious complications that can occur after SI, all patients should have regular follow-up (including an imaging study). Covered stents should always be available in the cathlab as a rescue device when implanting stents in coarctation of the aorta patients.

“…However, one must note that stent fracture and progression of the fracture can occur when Cheatham Platinum stents are applied [10]. In contrast, in our recently published series of Andrastents used in CoA this complication was not observed [6]. …”

“…Different stents were applied in this period depending on availability (bare metal: Palmaz, Cheatham Platinum (CP), Andrastents XL/XXL and covered with polytetrafluoroethylene CP stents). Characteristics of those stents have been described elsewhere [5, 6]. The stents were implanted retrogradely with the standard technique.…”

IntroductionStent implantation is an effective therapy for aortic coarctation (CoA) in adolescents and adults.AimTo present a unique group of patients with native coarctation of the aorta older than or equal to 46 years treated with bare metal or covered stents.Material and methodsSince 2002 we have performed stent implantations by applying bare metal stents or covered stents using femoral access in 24 patients aged 46 and older.ResultsWe used the Mullins technique in all cases, implanting different stents: Palmaz, Cheatham-Platinum (CP), covered CP or Andrastents XL/XXL. Twenty-one procedures were elective and 3 were urgent. Eighteen bare metal stents (2 stents in one patient) and 7 covered stents were used. All procedures were effective (CoA gradient reduced < 20 mm Hg), despite 2 migrations of bare metal stents. Mean gradient was reduced from 50.6 ±15.3 to 6.8 ±6.5 mm Hg (p < 0.001) and mean lumen diameter of stenosed aorta increased from 5.5 ±2.5 to 14.9 ±5.2 mm (p < 0.001). One special case is discussed – a 49-year-old man with end staged heart failure and severe CoA, who underwent a rescue procedure with a bare metal stent. One serious complication – stroke of the central nervous system – was observed in a 53-year-old woman during covered stent implantation (symptoms resolved during rehabilitation process).ConclusionsStent implantation of native coarctation of the aorta is also a safe procedure in the eldest patients and is associated with persistent relief of aortic obstruction.

Objectives: We present a first-in-man clinical use of a new hybrid design stent in stenosed large vessels. Its unique C and S polylinks prevent foreshortening without compromising its strength. Its thin profile permits use of smaller introducer sheaths. Background: Stent angioplasty is widely employed in large vessel and conduit stenosis. These procedures are associated with difficulties due to large stent profiles, stent fractures, foreshortening and recoil. Cobalt chromium stents have high tensile strengths compared to stainless steel stents. Methods: A retrospective analysis of feasibility and safety of a new Cobalt chromium stent in large vessels namely aorta, pulmonary arteries and outflow conduits was done from two institutions. Demographic patient details, procedural results, complications and medium term follow-up were analyzed. Stent recoil, foreshortening, fractures were assessed. Results: Twenty patients including three with aortic coarctations, seven with stenosed conduits and 10 with pulmonary artery stenosis underwent stent angioplasty using 23 stents. Three stents were deployed to expand further a previously implanted stent. Procedure was successful in all patients, lumen increased by 150-300%, gradients reduced in all patients. There was no stent recoil, foreshortening or fractures. There were no complications. At a follow up of 3-27 months, there were no stent related complications and the gradients remained stable. Conclusions: The new Zephyr stent was useful in a wide variety of stenotic lesions involving large vessels including those that were previously stented. Lack of stent recoil and foreshortening seems to be an advantage for this new stent that needs validation in larger multicenter studies.
