Summary
Coronary angiography is a reliable tool for assessing coronary artery disease, but advanced techniques like intravascular ultrasound and fractional flow reserve may be needed for borderline lesions.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Established criteria for balloon angioplasty success rates in 1988.
- Coronary intervention techniques have advanced, improving percutaneous revascularization safety and efficacy.
Purpose of the Study:
- To review the evolving assessment of coronary artery lesions.
- To highlight the role of advanced imaging and physiological measures.
Main Methods:
- Review of historical criteria and current advancements in coronary intervention.
- Discussion of coronary angiography, intravascular ultrasound, and physiological assessments (coronary flow reserve, fractional flow reserve).
Main Results:
- Coronary angiography is generally reliable but can be inconclusive for borderline lesions (40%-60% obstruction).
- Advanced anatomical and physiological assessments are crucial for comprehensive lesion evaluation.
Conclusions:
- Modern coronary intervention has improved outcomes for high-risk patients.
- Integrated anatomical and physiological assessments are essential for optimal percutaneous coronary intervention planning and execution.
