The CP stent--short, long, covered--for the treatment of aortic coarctation, stenosis of pulmonary arteries and caval veins, and Fontan anastomosis in children and adults: an evaluation of 60 stents in 53 patients

Abstract

Objective: To evaluate the feasibility and usefulness of the Cheatham platinum (CP) stent in a broad spectrum of lesions. Methods: Retrospective analysis of 60 implanted CP stents (11-80 mm lengths, 12 covered) between September 2001 and March 2004. Patients: 53 patients aged 2.5-68 years (median 17 years). Body weight ranged from 12-95 kg (median 52 kg). Thirty six patients had aortic (re)coarctation; seven of them had functionally interrupted aortic arches. Thirteen patients had pulmonary artery stenosis and four had stenosis of caval veins or conduits in a total cavopulmonary connection (TCPC). Results: Arterial pressure gradients dropped from 33 mm Hg (range 20-80 mm Hg) to 5 mm Hg (range 0-10 mm Hg) and pressure gradients in TCPC or caval veins dropped from 4 mm Hg (range 4-20 mm Hg) to 0 mm Hg (range 0-3 mm Hg). All stents were placed in the target lesion without complications. Three stent fractures without clinical instability were noted. Conclusions: The CP stent is suitable for the treatment of vessel stenosis in congenital heart diseases from childhood to adulthood. Whether these good results will be stable in the long term needs to be investigated.

NuMED covered cheatham‐platinum stent™ for the treatment or prevention of right ventricular outflow tract conduit disruption during transcatheter pulmonary valve replacement

“…There are several reports of use of the Covered Cheatham-Platinum Stent (CCPS) to prevent or treat aortic wall injuries associated with aortic coarctation, with >95% acute success rate and good midterm results [8][9][10][11]. Its use in the RVOT to repair wall injuries has also been reported [12,13].…”

“…Its use in the RVOT to repair wall injuries has also been reported [12,13]. The CCPS is currently only available in the US as an investigational device in the Prevention or Treatment of Aortic Wall Injury in Coarctation of the Aorta (COAST II) clinical study.…”

Transcatheter Stent Therapy in Children: An Update

“…Covered stents have been used successfully in the management of aortic coarctation and a number of reports document this experience [117][118][119][120][121][122][123][124][125][126][127][128][129][130][131][132][133][134][135][136] A variety of covered stents have been utilized and these include Jostent grafts (Jomed International, Helsingborg, Sweden), Cheatham-Platinum stents (NuMed Inc, Hopkinton, NY), AneuRx (Medtronic, Watford, UK), Advanta V12 (Atrium Medical, Hudson, NH) and others. While these stents are available outside the United States, they are not approved by the US Food and Drug Administration (FDA) for clinical use.…”

Transcatheter antegrade perforation and covered stent implantation to subatretic coarctation

“…In literature, carefully directed perforation of the obstruction utilizing a coronary wire and creation of a neo-aortic lumen, followed by balloon angioplasty and stent placement, successfully relieving the CoA in adolescents and adults was described (2,3). In this report, the patient was eight year old, and was Figure 1.…”

“…Subatretic coarctation is a complex form of aortic coarctation (CoA) with complete luminal obliteration (1)(2)(3). Surgical treatment of CoA has being performed successfully since 1940s.…”
