Buzzing the plaque: Coronary rotational atherectomy in its third decade

Area of Science:

• Cardiovascular Interventions
• Interventional Cardiology
• Medical Devices

Background:

• Percutaneous coronary intervention (PCI) is a common procedure for coronary artery disease.
• Complex calcified lesions pose significant challenges to successful stent deployment.
• Rotational atherectomy is a technique used to modify calcified lesions prior to stenting.

Discussion:

• Rotational atherectomy facilitates successful stenting in patients with limited therapeutic options.
• The procedure is crucial for managing complex calcified coronary lesions.
• It addresses the increasing prevalence of high-risk patients undergoing PCI.

Key Insights:

• Rotational atherectomy is an effective tool for enhancing stent success in challenging PCI cases.
• Independent predictors of mortality in this patient group include advanced age, diminished left ventricular ejection fraction (LVEF), renal insufficiency, and diabetes mellitus.
• The technique is vital for improving outcomes in a growing population of complex PCI candidates.

Outlook:

• Continued utilization of rotational atherectomy is supported by its role in managing high-risk, complex PCI patients.
• Further research may explore optimal patient selection and technique refinement.
• Advancements in interventional cardiology aim to improve safety and efficacy for complex coronary interventions.
