Novel long-neck sheath for endomyocardial biopsy

Area of Science:

• Cardiovascular Medicine
• Medical Devices
• Interventional Cardiology

Background:

• Endomyocardial biopsy is crucial for diagnosing cardiac conditions.
• Current methods can pose risks of cardiac trauma and prolonged procedure times.
• The internal jugular vein approach offers an alternative access route.

Purpose of the Study:

• To evaluate a novel long-neck sheath for endomyocardial biopsy.
• To assess the sheath's safety, efficacy, and ease of use.
• To determine if the sheath minimizes cardiac trauma and procedure duration.

Main Methods:

• A novel long-neck sheath was developed for internal jugular venous access.
• The sheath was designed to stabilize biopsy forceps for atraumatic septal targeting.
• Clinical feasibility and performance were assessed during endomyocardial biopsy procedures.

Main Results:

• The sheath was easy to advance and position within the heart.
• It provided a stable platform for efficient and safe bioptome delivery to the target septal site.
• The design minimized repetitive crossing of right heart structures.

Conclusions:

• The novel long-neck sheath facilitates safe and effective endomyocardial biopsy.
• This device has the potential to reduce patient trauma and radiation exposure.
• It may also lead to shorter procedure times in interventional cardiology.
