Values are n (%) or mean ± SD.

IVUS = intravascular ultrasound; NERS = New Risk Stratification; RCA = right coronary artery; SYNTAX = Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery; TIMI = Thrombolysis In Myocardial Infarction; other abbreviations as in Table 1.

  • Left anterior descending artery (LAD) was treated as main branch in all patients, with exception for 3 in the DK group and 2 in the culotte group, for whom the left circumflex artery (LCX) was considered the main branch.
