Immediate and intermediate term results of cheatham platinum stenting for native coarctation of aorta in adults

Resumen

Background: aortic coarctation is an important cause of hypertension. Surgical repair was considered the conventional treatment for native aortic coarctation while stenting emerged recently as an alternative to surgical repair. Objective: To evaluate the immediate and intermediate results of Cheatham Platinum (CP) stenting for native coarctation of aorta. Methods: This is a prospective study done in Ibn Al-Bitar cardiac Centre, included 32 consecutive adult patients with native coarctation of aorta. Clinical, hemodynamic and procedural data were collected and analyzed for each patient. Covered CP stent was used and mounted on the Balloon-in-Balloon catheter (BIB) in most of the cases. The technique was considered effective if the invasive grade was decrease to <20 mmHg and increased the angiographic diameter >50%. Results: A total of 32 patients had the procedure done with a success rate of 93.4%.  Peak gradient across the coarctation fell from 60.0±21.960 to 10.0± 19.821 mmHg post procedure (P, 0.0001). There was no major complications, with no deaths. Systolic blood pressures fell from 164.6±25.889 mmHg to 138.1±17.006 mmHg immediately after stenting and 134.3±12 mmHg at 6 months. No significant complications were seen during procedure and at 6 months follow up. Conclusion: aortic coarctation stent of adults have better fast clinical and angiographic consequences and continued hemodynamic advantages at 6-12 months.
