ROBITAL Technique: Combination of Sequential ROtational and orBITAL Atherectomy in Management of Complex Coronary...

Area of Science:

• Cardiovascular Interventions
• Interventional Cardiology
• Medical Device Technology

Background:

• Heavily calcified coronary artery disease presents significant challenges in percutaneous coronary interventions, often resulting in suboptimal stent expansion and poor patient outcomes.
• Various calcium modification techniques exist, including rotational atherectomy and orbital atherectomy, each with distinct mechanisms, advantages, and limitations.

Purpose of the Study:

• To provide a comprehensive overview of established and emerging calcium modification strategies for complex lesion preparation.
• To introduce and detail the novel ROtational orBITAL atherectomy (ROBITAL) technique, a sequential approach combining rotational and orbital atherectomy.

Main Methods:

• The ROBITAL technique involves using rotational atherectomy to establish an initial lumen, followed by orbital atherectomy for comprehensive plaque modification.
• The article illustrates the rationale, technical aspects, and clinical applications of the ROBITAL approach, including its use in complex left main bifurcation lesions.

Main Results:

• The sequential combination of rotational and orbital atherectomy aims for more uniform and extensive plaque modification.
• The ROBITAL technique is presented as a viable option for complex lesion preparation, particularly in challenging anatomical locations.

Conclusions:

• The ROBITAL technique represents an evolving strategy in calcium modification, expanding treatment options for complex coronary lesions.
• This approach offers a potentially safe, efficient, and cost-effective solution for patients with high-risk, heavily calcified coronary artery disease.
