Cutting balloons versus stenting in small vessel coronary disease, angiographic and clinical outcomes

الملخص EN

Background & Air : Vest size s inversely cordite with the risk of restenosis and adverse outcome after percutaneous coronary intervention,.

There are no well defied recommendations reading he intervention of choice in the setting of small coronary vests.

This is currently considered as a great challenge to all coronary artery interventionists.

The purpose of this study was to determine the impact of cutting balloon angioplasty (CBA) compared with coronary stents on clinical and angiographic outcomes in small coronary vessels (< 3 mm in diameter) Patients & ethos : 118 patients with symptomatic coronary artery disease were divided into 3 groups according to the treatment strategy : drug doting stent (DES) ; hare metal stent (BMS) ; cutting balloon angioplasty Repeat angiography was done at 6-month follow up.

The primary end-pint of the study was the incidence of angiographic restenosis (>50 % diameter stenosis) at follow up.

Death, Myocardial infarction, stroke and target vessel revascularization were assessed as secondary end points.

Results : baseline clinical and angiographic characteristics were similar among the 3 groups The DES group had the best immediate and late angiographic results Surprising the CB group showed better late angiographic result when compared with the BMS group, in terms of better MLD, net gain, and percent restenosis rate with statistically significant values.

Conclusions : DES in general is the treatment of choice so far for patients with small cursory artery disease CBA showed favorable immediate post procedural results and better late clinical and angiographic results comparing with bare metal stent, hence cutting balloon could be a good tool in this subset of patients with considerably lesser cost comparing with BMS.
