ABSTRACT
With increasing incidence of stent deployment, the problem of ISR "the Achilles heel of stenting" is becoming increasingly prevalent and remains the major limitation of coronary catheter based interventions. Aim of the work: To evaluate the mid-term clinical outcome after PCI for treatment of different patterns of ISR and to make angiographic follow-up for patients with clinical restenosis. Thirty patients with ISR underwent successfi1 PC1 from September 2002 in Nasr City Insurance Hospital and were followed- up clinically and by exercise stress testing for six months after the procedure. Angiographic follow-up was done -for patients with recurrent symptoms [one patient] or with positive stress test results at follow up [one patient]. 80% of our patients underwent successful PCI using conventional balloon and in the remaining 20% cutting balloon was used. We found no difference between both for treatment of ISR at SLY months follow- up [P=0.66]. In the current study, only two patients [6.7%] had clinical and angiographic ISR. The remaining [93.3%] had a favorable clinical outcome. In conclusion: Repeat balloon angioplasty for the treatment of ISR is an easy and safe procedure with high procedural success, but its worthy to say that best management of ISR is not completely established. So, prevention of ISR at the outset should be the ultimate aim and in this issue drug-eluting stents [DES] may be an outstanding option
