Abstract

Sinus node artery (SNA) occlusion is a rare complication of percutaneous coronary intervention and usually has a benign prognosis; sinus arrest may occur but frequently resolves. We report a case of unresolved SNA obstruction following percutaneous coronary intervention of the mid-right coronary artery, for which permanent pacemaker implantation was required. (Level of Difficulty: Beginner.).

Keywords: LCx, left circumflex artery; PCI, percutaneous coronary intervention; RCA, right coronary artery; SNA, sinus node artery; bradycardia; coronary angioplasty; pacemaker; sinus node arrest.
