Technical considerations for percutaneous pulmonary artery cannulation for mechanical circulatory support

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Percutaneous pulmonary artery cannulas are vital for mechanical circulatory support and left ventricular venting.
• Their rapid deployment with imaging guidance facilitates complex cardiac procedures.

Purpose of the Study:

• To review institutional experience with right atrium to pulmonary artery cannulations.
• To describe cannulation strategies for right ventricular support and left ventricular venting.

Main Methods:

• Retrospective review of institutional and technical experience.
• Analysis of right atrium to pulmonary artery cannulation procedures.

Main Results:

• Six distinct cannulation strategies were identified and categorized.
• Strategies include total and partial right ventricular assist support and left ventricular venting.
• Both single-lumen and dual-lumen cannulas are applicable for right ventricular support.

Conclusions:

• Percutaneous cannulation is beneficial for isolated right ventricular failure.
• Pulmonary artery cannulation serves as effective left ventricular venting for bypass or ECMO circuits.
• This article provides a technical reference for cannulation, patient selection, and management.
