culprit vessel
The coronary artery responsible for the acute coronary syndrome being treated.
Full Definition
In acute coronary syndrome, the specific coronary artery that contains the ruptured plaque or acute thrombosis causing the clinical presentation. Identification of the culprit vessel is crucial for directing primary PCI efforts and determining the most appropriate revascularization strategy. The culprit vessel is typically identified through a combination of ECG changes, echocardiographic wall motion abnormalities, and angiographic findings.
Usage
Usage note: Use specifically for the vessel causing acute symptoms, not chronic disease.
