USE OF COVERED CHEATHAM-PLATINUM STENT IN THE TREATMENT FOR COARCTATION OF THE AORTA

Abstract

Objective: To share our institutional experience of cCP stent (Covered Cheatham-Platinum stent) implantation in children and adults with native and Re-COA (Coarctation of Aorta).

Study Design: A retrospective cross sectional study.

Place and Duration of Study: This study was conducted at Armed Forces Institute of Cardiology/National Institute of Heart Diseases (AFIC/NIHD) Rawalpindi Pakistan, from Jan 2016 to Oct 2018.

Materials and Methods: Retrospective analysis of all consecutive patients who underwent cCP stent implantation for COA was carried out to assess its immediate, short and intermediate term efficacy and safety.

Results: A total of 25 individuals diagnosed with significant COA (native and re COA) with a median age of 18years were enrolled. About 15 were male (M: F, 1.5: 1). 23 pt’s had native coarctation and 2 had re coarctation. Mean follow up duration was 14.8 months (range 1 to 29 months). Immediate success was achieved in 100% by significant reduction of pre vs post stenting mean peak systolic pressure gradient (68 mmHg vs 12 mmHg, p<0.001) and increase in the mean minimum aortic diameter (3.5 mm vs 12.8 mm, p<0.001). Mean systolic and diastolic BP was significantly reduced after the procedure in 18 (72%). Complications occurred in 18 (72%), which included transient pulse loss in 16 (64%) and restenosis in 2 (8%).

Conclusion: Percutaneous CP stent implantation is a very effective and safe intervention for both native and re coarctation in reducing the coarctation gradient and increasing the lesion diameter.
