Which treatment method is used for neoatherosclerosis?

• A. Stenting with balloon-expandable grafts
• B. Cutting balloon, atherectomy, and IVL
• C. Cryoplasty
• D. Pharmacologic therapy alone

Answer: (B)

Neoatherosclerosis is a condition that can occur after coronary interventions, such as stent placement. It involves the development of new atherosclerotic lesions within or adjacent to the stented area, often driven by factors related to the healing response and the ongoing pathological processes in the vessel wall.

The correct treatment approach for neoatherosclerosis typically involves advanced techniques that can effectively address the complex nature of these lesions. The use of a cutting balloon, atherectomy, and intravascular lithotripsy (IVL) is particularly relevant in this context. These methods can facilitate the modification of plaque and effectively reduce the volume of neointimal hyperplasia and calcified lesions.

Cutting balloons allow for more controlled dissections and can help to facilitate further interventions. Atherectomy serves to physically remove plaque material from the arterial wall, which can be useful in addressing both the neoatherosclerotic changes and in preventing the progression of the disease. Intravascular lithotripsy, on the other hand, utilizes sound waves to fracture calcified lesions, making it easier to manage complex cases.

This comprehensive approach provides a more effective strategy for managing the challenges posed by neoatherosclerosis, illustrating why this combination of techniques is the
