[Rotational atherectomy (Rotablator®) : complementary technique in management of undilatable coronary lesions]

Area of Science:

• Interventional Cardiology
• Cardiovascular Interventions
• Medical Device Technology

Background:

• Interventional cardiology has evolved significantly over 40 years.
• Percutaneous techniques now address previously unfavorable anatomical situations requiring surgical revascularization.
• Complex lesions, including fibrotic and calcified ones, pose challenges for dilation and stent implantation, leading to complications and poor outcomes.

Purpose of the Study:

• To describe the rotational atherectomy procedure.
• To outline the indications for rotational atherectomy.
• To present the clinical results of rotational atherectomy for treating challenging coronary lesions.

Main Methods:

• Review of rotational atherectomy (RA) procedure.
• Analysis of indications for RA in interventional cardiology.
• Evaluation of clinical outcomes associated with RA.

Main Results:

• Rotational atherectomy is a complementary technique for treating fibrotic and calcified lesions.
• The procedure has become feasible and safe for complex lesion subsets.
• RA facilitates stent delivery and implantation in previously challenging anatomies.

Conclusions:

• Rotational atherectomy has expanded the applicability of percutaneous coronary interventions.
• The technique offers a safe and effective solution for managing difficult-to-treat fibrotic and calcified lesions.
• RA improves procedural success rates and long-term outcomes in selected patients.
