Abstract:
Objective To assess the immediate and mid-term outcomes of the combination of rotational atherectomy(RA)with stents on heavily calcified lesions.Methods Twenty-one patients with severely calcified lesions were treated with RA followed by stenting.Six cases had intravascular ultrasonic guidence during the procedure.The success rate of the procedure and the 6-month-follow-up results were analyzed.Results The burrs passed through the lesions successfully in all cases.All the lesions were either type B2 or C calcified lesions under angiography.Seventeen cases chosed the 1.25 mm bur while 2 cases used 2 burrs in the proceudre.All patients received PTCA after RA and stenting was performed in 19 cases.One patient had severely coronary vasospasm and 2 cases showed no-flow after PCI.None of the cases needed emergence bypass graft surgery and the mortality was null.In-stent restenosis was found in 2 cases at 6 months follow-up angiogram.Conclusion The combination of rotational atherectomy with stents therpy can selectively ablate calcific plaque and may increase the success rate of the procedure.
