Insights
A patient with three-vessel coronary artery disease experienced recurrent angina after stenting the right coronary artery. Urgent bypass surgery was performed, with intraoperative flow assessment of the native right coronary artery.
Area of Science:
- Cardiology
- Vascular Surgery
Background:
- Coronary artery disease (CAD) is a leading cause of mortality worldwide.
- Percutaneous coronary intervention (PCI) with stenting is a common treatment for obstructive CAD.
- Recurrent symptoms after PCI may indicate stent failure or progression of disease.
Observation:
- A patient with three-vessel CAD underwent stenting of the right coronary artery (RCA).
- The patient presented with recurrent angina 12 days post-procedure.
- Urgent coronary artery bypass grafting (CABG) was indicated without repeat angiography.
Findings:
- Intraoperative assessment of native right coronary artery flow was performed using an ultrasonic flow probe.
- This assessment provided real-time hemodynamic data during the CABG procedure.
Implications:
- Intraoperative flow assessment can be valuable in managing complex CAD cases.
- This case highlights the importance of evaluating native vessel patency in urgent revascularization scenarios.
- Further research into the utility of intraoperative flow probes in optimizing CABG outcomes is warranted.
Abstract:
We report the case of a patient with three-vessel coronary artery disease whose right coronary artery had been stented at the time of the diagnostic procedure. He had recurrent angina 12 days later and was transferred for urgent coronary artery bypass grafting. No repeat coronary angiography was performed. In the operating room, the flow on the native right coronary artery was determined with an ultrasonic flow probe.
