Summary
Spontaneous coronary artery dissection (SCAD) is a key cause of heart attack in young women. This study reviews percutaneous interventions for higher-risk SCAD cases and proposes an algorithm for managing these patients.
Area of Science:
- Cardiology
- Vascular Biology
Background:
- Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of myocardial infarction (MI), especially in younger women.
- Current management strategies for SCAD are largely based on observational data, with intervention reserved for specific high-risk scenarios.
Observation:
- SCAD management often favors conservative approaches, but intervention is indicated for compromised coronary blood flow, left main involvement, ongoing ischemia, or hemodynamic instability.
- Randomized trials comparing revascularization strategies for SCAD are absent, unlike in atherosclerotic coronary artery disease.
Findings:
- This paper presents 4 cases of SCAD from the authors' institution.
- A literature review on percutaneous revascularization in SCAD patients is provided.
- A step-wise algorithm for percutaneous intervention in higher-risk SCAD is proposed.
Implications:
- The proposed algorithm may guide interventional cardiologists in managing complex SCAD cases.
- Further research, including randomized controlled trials, is needed to establish optimal revascularization strategies for SCAD.
- This work contributes to a better understanding of interventional approaches for SCAD, a condition affecting a distinct patient population.
