Glossary Entry: Rotational Atherectomy Catheter

Overview

Definition: A catheter device used in medical practice to treat coronary artery disease by removing plaque build-up through a rotational cutting mechanism.

Detailed Description

Types and Variations

Variations: Different sizes and models of rotational atherectomy catheters may be available, each designed for specific applications in treating varying degrees of blockages in the coronary arteries.

Indications

Common Uses: This device is commonly used in cases of severe coronary artery disease where traditional methods like angioplasty may not be effective due to the presence of hard calcified plaque.

Insertion and Placement

Procedure: The rotational atherectomy catheter is inserted into the affected coronary artery over a guidewire, and the rotating burr at the tip of the catheter is used to ablate and remove the plaque, improving blood flow.

Clinical Considerations

Potential Complications

Risks: Potential complications of using a rotational atherectomy catheter include vessel perforation, dissection, and distal embolization of plaque debris.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of the catheter include ensuring correct sterilization procedures and storage to prevent contamination and damage to the device.

Additional Information

Related Devices

Associated Terms: Intravascular ultrasound (IVUS) catheter, coronary stent, and balloon angioplasty catheter are often used in conjunction with a rotational atherectomy catheter during complex coronary interventions.

Innovations and Advancements

Recent Developments: Recent advancements in rotational atherectomy catheter technology include the development of smaller, more flexible catheters with improved cutting efficiency and safety features.

Regulatory and Safety Notes

Regulations: The use of rotational atherectomy catheters is subject to regulatory guidelines to ensure patient safety and efficacy in treating coronary artery disease.
