Insights
This study shows a new technique using intravascular lithotripsy balloons to treat severe coronary artery calcification in large vessels. The method successfully addressed in-stent restenosis, expanding treatment options for complex coronary interventions.
Area of Science:
- Interventional Cardiology
- Cardiovascular Devices
- Medical Technology
Background:
- In-stent restenosis is a significant complication after coronary artery stenting.
- Severe coronary calcification poses challenges for stent deployment and expansion.
- Treating calcified lesions in large-caliber coronary arteries (≥6.0 mm) is complex.
Abstract:
We present a patient with in-stent restenosis due to severe coronary calcification with asymmetric stent expansion and resulting stent eccentricity in a very large (6.0 mm) caliber coronary artery. We demonstrate the feasibility of using the largest commercially available coronary intravascular lithotripsy balloon (4.0 mm) along with a "buddy" balloon inflated simultaneously to treat focal coronary artery calcification in a vessel with a diameter significantly larger than the largest commercially available coronary intravascular lithotripsy balloon. To our knowledge, this is the first demonstration of this technique in coronary artery intervention.
