Percutaneous Intervention of a Single Coronary Artery in the Setting of Acute Coronary Syndrome.

Performing intervention of a single coronary artery (SCA) is challenging and technically difficult since a severe complication may be catastrophic if occurred. It requires a proper selection of instruments and well experienced operator to perform the intervention. However, a definitive standardization treatment for those patients is difficult; each case should be treated individually, according to the anatomical variations. We present three rare cases of SCA in setting of acute coronary syndrome (ACS) and culprit lesion in right coronary artery (RCA), treated successfully with percutaneous coronary intervention.
