Insights
Cardiogenic shock after percutaneous coronary intervention (PCI) in an 82-year-old patient was successfully treated with atrial pacing when medications failed. This highlights pacing as a key intervention for PCI-induced cardiogenic shock.
Area of Science:
- Cardiology
- Interventional Cardiology
- Electrophysiology
Background:
- Percutaneous coronary intervention (PCI) can precipitate cardiogenic shock.
- Atrioventricular junctional rhythm is a potential complication post-PCI.
Observation:
- An 82-year-old female developed cardiogenic shock due to atrioventricular junctional rhythm immediately after PCI.
- Pharmacotherapy proved ineffective in managing the shock.
Findings:
- Atrial pacing was successfully applied, reversing the cardiogenic shock.
- Diagnosis pointed to PCI-related injury of the sinuatrial nodal artery, causing atrial contractility loss and arrhythmia.
Implications:
- Atrial pacing is a viable and optimal management strategy for cardiogenic shock post-PCI.
- Preoperative risk assessment and established emergent protocols are crucial for high-risk patients undergoing PCI.
Abstract:
An 82-year-old female patient undergoing cardiogenic shock caused by atrioventricular junctional rhythm immediately after percutaneous coronary intervention (PCI) is described. Pharmacotherapy was invalid, and subsequent application of atrial pacing reversed the cardiogenic shock. PCI-related injury of sinuatrial nodal artery leading to acute atrial contractility loss, accompanied by atrioventricular junctional arrhythmia, was diagnosed. We recommend that preoperative risk evaluation be required for multi-risk patients. Likewise, emergent measures should to be established in advance. This case reminds us that atrial pacing can be an optimal management technique once cardiogenic shock has occurred.
