A Prospective Randomized Trial of Sirolimus-Eluting Stents Compared to Balloon Angioplasty for Restenosis of Drug-Eluting Coronary Stents - CRISTAL


Although the incidence of in-stent restenosis (ISR) has been significantly reduced with drug-eluting stents (DES), the optimal strategy for treating DES-ISR is unclear. The CRISTAL trial sought to compare outcomes after repeat DES implantation versus balloon angioplasty alone in the treatment of DES-ISR.
