title: Cheatham platinum (CP) and Palmaz stents for cardiac and vascular lesions treatment in patients with congenital heart disease.
abstract: OBJECTIVE
  To compare Cheatham Platinum (CP) stent and Palmaz stent for the treatment of native and postoperative lesions of congenital heart disease (CHD) patients.
  
  
  RESULTS
  From January 1998 to December 2007, 96 CP stents and 77 Palmaz stents were implanted in 89 and 64 CHD patients. All stents could be deployed. Decrease in pressure gradient was higher with the CP than with the Palmaz stent (36.1 +/- 23 and 23.4 +/- 18.3 mmHg, p = 0.004). The procedure was more often successful with a CP than with a Palmaz stent (96% and 88% of patients, p = 0.03). Stent-related complications were more rarely observed with the CP than with the Palmaz stent (9% and 27%, p = 0.007). The incidence of vascular dissection was lower with CP than with Palmaz stent (1% and 6%), the incidence of stent migration was similar in the two groups (8% and 6%). Balloon burst, never observed in the CP stent group, was frequent in the Palmaz group (0% and 11%, p = 0.001). There were no procedural deaths. The need for urgent surgery was similar in the two groups (2% and 1%).
  
  
  CONCLUSIONS
  Our findings show a superiority of the CP over the Palmaz stent concerning efficacy and reduction of complications rate for the treatment of cardiac and vascular lesions of children and young adults with CHD.
