Planned RA was defined as RA performed directly before balloon predilation, while bailout RA was RA performed after failure to balloon predilation or stents deliver to target lesions. Slow flow/no re-flow was defined as less than Thrombolysis in Myocardial Infarction (TIMI) III flow grade in the absence of dissection or thrombus immediately after RA. A final residual stenosis \u003c30% complied with TIMI flow grade III after stents placement was considered procedural success. The procedure was considered a failure if patients received emergent coronary artery bypass grafting (CABG) and/or PCI, or other severe RA-related complications (death, coronary perforation) developed before discharge. Periprocedural myonecrosis was defined as troponin I above threefold of the upper limit of normal or a 50% increase from the baseline level [7].","divisions":[{"label":"title","span":{"begin":0,"end":15}}],"tracks":[]}
