Insights
This case study highlights spontaneous multivessel coronary artery dissection, a rare condition. Successful treatment with percutaneous coronary intervention using everolimus-eluting stents demonstrates effective management for this critical cardiovascular event.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Coronary artery dissection is a rare cause of myocardial infarction.
- Spontaneous coronary artery dissection (SCAD) can affect multiple vessels.
Observation:
- A 43-year-old woman presented with non-ST elevation myocardial infarction.
- Initial catheterization revealed left anterior descending artery dissection and right coronary artery chronic total occlusion.
- Persistent chest pain led to repeat catheterization, revealing right coronary artery dissection.
Findings:
- Successful stenting of the left anterior descending artery dissection with everolimus-eluting stents.
- Successful stenting of the right coronary artery dissection with everolimus-eluting stents.
- Excellent clinical and angiographic outcomes were achieved for both coronary dissections.
Implications:
- Spontaneous multivessel coronary artery dissection is a critical diagnosis to consider in acute coronary syndromes.
- Percutaneous coronary intervention is a viable and effective treatment strategy for spontaneous multivessel coronary artery dissection.
- Everolimus-eluting stents provide favorable outcomes in managing complex coronary dissections.
Abstract:
We present a case of a 43-year-old woman who presented with a non-ST elevation myocardial infarction. During her first cardiac catheterisation, she was diagnosed with a chronic total occlusion of the right coronary artery and a flow limiting dissection of her middle left anterior descending artery. The dissection of the left anterior descending artery was stented with two overlapping everolimus-eluting stents. There were no complications from this percutaneous coronary intervention. On the following day, the patient continued to have persistent chest pain and returned to the catheterisation laboratory. It was then found that the patient had a total occlusion of the right coronary artery secondary to dissection. This was also stented with three everolimus-eluting stents with excellent clinical and angiographic results. It is important to consider spontaneous multivessel coronary dissections which can be treated successfully with percutaneous coronary intervention.
