Insights
This case study details a novel 3-stent strategy for treating spontaneous coronary artery dissection (SCAD) in an unstable patient. This sequential stent-sandwiching technique successfully managed a complex myocardial infarction case.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Biology
Background:
- Spontaneous Coronary Artery Dissection (SCAD) is a rare cause of myocardial infarction, particularly in older women.
- Complete heart block and acute ST-segment-elevation myocardial infarction (STEMI) indicate severe coronary artery compromise.
Observation:
- A 78-year-old woman presented with STEMI and complete heart block.
- Coronary angiography identified spontaneous coronary artery dissection (SCAD) in the right coronary artery.
- The patient remained hemodynamically unstable, necessitating urgent intervention.
Findings:
- A novel "sequential stent-sandwiching" technique was employed for percutaneous coronary intervention.
- This involved sealing the distal and proximal edges of the dissection before stenting the midsegment.
- A successful 3-stent strategy was implemented to manage the complex SCAD.
Implications:
- This case demonstrates a viable percutaneous coronary intervention strategy for hemodynamically unstable SCAD patients.
- The "sequential stent-sandwiching" approach offers a potential solution for complex SCAD lesions.
- Further research into specialized techniques for SCAD management is warranted.
Abstract:
A 78-year-old woman presented with acute inferior ST-segment-elevation myocardial infarction and complete heart block. Angiography revealed spontaneous coronary artery dissection (SCAD) of her right coronary artery. Given her ongoing instability, we proceeded to primary coronary intervention. A strategy of sealing the distal lesion edge followed by the proximal edge containing the intramural hematoma before placing a final stent to the midsegment was decided on (3-stent strategy). Our case represents the second such "sequential stent-sandwiching" report and provides a strategy for percutaneous coronary intervention in hemodynamically unstable patients with SCAD.
