Cardiac Catheterization II: Right Heart Catheterization

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Area of Science:

Medical Robotics
Cardiovascular Interventions
Biomedical Engineering

Background:

Cardiovascular disease is a leading global cause of death, driving the need for advanced endovascular tools.
Current procedures using guide catheters and guidewires involve significant X-ray exposure for clinicians.
Existing robotic catheter systems are often bulky, require specialized facilities, and have limited instrument compatibility.

Purpose of the Study:

To design, fabricate, and validate a portable and versatile catheter robot for cardiovascular interventions.
To address the limitations of current robotic systems, including size, compatibility, and facility requirements.
To enhance clinician safety by reducing radiation exposure during endovascular procedures.

Main Methods:

Developed a 4 degree-of-freedom catheter robot with a compact, modular design.
Integrated direct drive motors and advanced mechatronics for precise control.
Analytically modeled the drive mechanism and experimentally evaluated tracking, force, and torque performance.
Tested the robot's ability to manipulate commercial cardiovascular instruments (1-9 F diameter).

Main Results:

The portable robot is approximately 90% smaller than current state-of-the-art systems.
Experimental validation confirmed clinically relevant actuation of guidewires and guide catheters.
The system demonstrated safe operation within force and torque limits, preventing vascular tissue damage.
Successful simulation of percutaneous coronary intervention on a 3-D heart model.

Conclusions:

The developed portable catheter robot offers a versatile and compact solution for endovascular procedures.
The system effectively manipulates cardiovascular instruments, reducing clinician radiation exposure.
Its portability and compatibility enhance applicability across a wide range of cardiovascular interventions.
This technology holds significant clinical potential for improving patient outcomes and procedural efficiency.
