Background. Sinus node artery occlusion (SNO) is a rare complication of percutaneous coronary intervention (PCI). We analyze both the short- and long-term consequences of SNO. Methods. We retrospectively reviewed 1379 consecutive PCI’s involving RCA and Cx arteries performed in our heart institute from 2016 to 2019. Median follow-up was 44 ± 5 months. Results. Among the 4844 PCIs performed during the study period, 284 involved the RCA and the circumflex’s proximal segment. Periprocedural SNO was estimated by angiography observed in 15 patients (5.3%), all originated from RCA. The majority of SNO occurred during urgent and primary PCIs following acute coronary syndrome (ACS). Sinus node dysfunction (SND) appeared in 12 (80%) of patients. Four (26.6%) patients had sinus bradycardia, which resolved spontaneously, and 8 (53.3%) patients had sinus arrest with an escaped nodal rhythm, which mostly responded to medical treatment during the first 24 hours. There was no association between PCI technique and outcome. Three patients (20%) required urgent temporary ventricular pacing. One patient had permanent pacemaker implantation. Pacemaker interrogation during follow-up revealed a recovery of the sinus node function after one month. Conclusion. SNO is rare and seen mostly during angioplasty to the proximal segment of the RCA during ACS. The risk of developing sinus node dysfunction following SNO is high. SND usually appears during the first 24 h of PCI. The majority of SND patients responded to medical treatment, and only in rare cases were permanent pacemakers required.

Complete occlusion of the sinoatrial node artery can be a complication of percutaneous intervention (PCI) to the right coronary artery (RCA). When this happens, dysfunction of the sinus node may follow resulting in sinus arrest. When this occurs, it is usually transient and as such, is typically not accompanied by hemodynamic instability. Permanent sinus arrest and shock state may, however, occur on rare occasions. The presence of junctional rhythms on the electrocardiogram (ECG) may predict the occurrence of these permanent arrhythmias and cardiogenic shock. In this case report, we present a 78-year-old woman who developed cardiogenic shock secondary to sinus arrest following PCI to RCA. Her ECG showed junctional rhythm, and she went on to require permanent ventricular pacing. This illustrates a known but rare complication of PCI to RCA.

Transient sinus arrest due to sinus node artery thrombus after revascularisation of the left circumflex artery

We present a case of sinus arrest and junctional escape rhythm from sinus node artery (SNA) thrombus in a 55-year-old man after revascularisation of right coronary and proximal circumflex arteries for infero-posterior wall ST-segement elevation myocardial infarction (STEMI). Sinus arrest from occlusion of the SNA is uncommon. The ensuing bradycardia may have haemodynamic consequences requiring temporary pacing but is almost always self-limited.
