Key result
RCA PCI causes SA node artery occlusion, triggering sinus arrest and cardiogenic shock.
Why the study?
Complete occlusion of the sinoatrial node artery causing permanent sinus arrest and cardiogenic shock after PCI to the RCA is a rare but serious complication.
Case Report (n=1)
Complete occlusion of the sinoatrial node artery during PCI to the RCA can rarely lead to permanent sinus arrest and cardiogenic shock requiring permanent pacing.

Rare permanent sinus arrest after RCA PCI from SA node artery occlusion warrants vigilance; case report leaves open whether junctional rhythms predict this outcome.
Ezeh et al. (2022) conducted a case report in Cardiogenic shock secondary to sinus arrest (n=1). Percutaneous intervention (PCI) to the right coronary artery was evaluated. Percutaneous intervention to the right coronary artery caused complete occlusion of the sinoatrial node artery, leading to permanent sinus arrest and cardiogenic shock in a 78-year-old woman.
