Overview
Historical Perspective
Classification
Coronary revascularization may refer to;
Indications
- Treatment decisions regarding coronary revascularization should be done regardless of sex, race, and ethnicity.[1]
- Decision regarding coronary revascularization should be patient-centered, meaning that physicians should consider patient's wishes, health literacy, and cultural believes.[1]
- Based on ACC/AHA/SCAI 2021 guideline, for patients with unclear optimal treatment strategy a Heart Team including an interventional cardiologist, cardiac surgeon, and clinical cardiologist is recommended to assess the patient's outcome. The following table demonstrates factors that can be considered by the Heart Team:[1]
| Coronary Anatomy | *Left main disease *Multivessel disease *Complicated anatomy (such as bifurcation disease, and high SYNTAX score |
|---|---|
| Comorbidities | *Coagulopathy *Frailty *Diabetes *Valvular heart disease *Cancer *Systolic dysfunction *End-stage renal disease *Aortic aneurysm *Calcified aorta *Immunosuppression *Chronic obstructive pulmonary disease *History of cerebral stroke *Debilitating neurological disorders *Cirrhosis/liver disease |
| Procedure | *Access site for percutaneous coronary intervention (PCI) *Risk of surgery *Local and regional clinical outcomes *Risk of percutaneous coronary intervention (PCI) |
| Patient | *Patient preferences, religional believes, education, and knowledge *Incompliant to dual antiplatelet therapy *Patient social supports *Unstable presentation or shock |
Coronary Anatomy
- Based on ACC 2021 guideline, coronary angiography is still the default method to determine coronary anatomy and stenosis degree.[1]
- Significant stenosis is one of the indications for the revascularization procedure, which has been defined as the following observations in coronary angiography:[1]
- The fact that whether visually estimated diameter stenosis or quantitative coronary angiography can better predict the the functional significance of a coronary stenosis is controversial. [2]
- Although the lesion's length can affect the ischemia severity, there are no standard cutoffs for length of the lesions when sever stenosis is determined.
What Procedure to Choose?
SYNTAX Score
- SYNTAX score derived from a clinical trial with the same name which predicts the grade of the anatomic complexity and can be used as a decision-making tool. This score is a guide for the selection of a revascularization procedure in patients with multivessel coronary artery disease.[3]
Fractional flow reserve and instantaneous wave-free ratio
Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are commonly used to assess the lesion significant. Fractional flow reserve (FFR) compares the maximal blood flow distal to the lesion to the normal maximal blood flow. On the other hand iFR compares the instantaneous wave-free ratio of the coronary pressure distal to the lesion during the diastole with the aortic pressure.[1]
- Reported in numbers of trials which used FFR, FFR-guided PCI was successful in lowering the revascularization rate in patients with stable coronary artery disease and functionally significant stenosis.[4]
Outcome
- After controlling baseline comorbidities and treatment strategies, outcome of coronary revascularization were same among different races as well as males and females.[1][5][6]
