Catheter Magnetic Guidance
Advantages and Limitations
 
Advantages: 

The advantages to manually deflected catheters are:
	larger flexibility
	possibility of 3D movements
	more stable endocardial contact 
 shorter fluoroscopy time
	no radiation exposure for the physician
	shorter procedure time

Limitations:

Catheter magnetic guidance cannot be used on patients:
	with magnetic prosthesis or electronic implant (e.g. pacemaker, defibrillators, vascular clips)
	with a body weight weigh greater than 300 lbs
	claustrophobic
	with hemodynamic instability
	with recent myocardial infarction or cardiac surgery
