Background & Objective: The aim of this research is To report the results of covered Cheatham-Platinum (CP) stents implantation in patients with complex aortic coarctation Methods & Materials: Between January 2011 and march 2013, we implanted covered Cheatham-Platinum stents in 20 patients with complex aortic coarctation .

All procedures were performed under general anesthesia During follow-up, patients underwent physical examination, including blood pressure measurements, electrocardiogram, and echocardiography, at 1, 3, 6 and 12 months.

Magnetic resonance (MR) or CT angiography were performed at 3 and 12 months after the procedure.

Results: The stents used ranged from 23 to 44 mm in length.

The mean fluoroscopy and procedure times were 17 ± 8 and 83 ± 16 minutes, respectively.

After implantation, the gradient across the stenosis decreased significantly (pre stent: median value42 mm Hg [range 20-85 mm Hg] vs post stent: median value 0 mm Hg [range 0-4 mm Hg].

Vessel diameter increased from a median value of 5 mm (range 0-12) to a median value of 16 mm (range 11-26).., and on angiographic control, the stenoses had been relieved and the aneurysms completely excluded.

During a median follow-up of 12 months (1-21 months), the patients were stable without complications.

One patient developed intrastent restenosis(10 months after implantation) due to a significant endothelial proliferation and was successfully treated by high-pressure balloon angioplasty.

There were no deaths or serious complications Conclusion: Covered Cheatham-Platinum stents are safe and very effective tools for the treatment of complex aortic coarctation and gives good immediate results.
