Complications associated with balloon-tipped, flow-directed catheters.

In summary, the balloon-tipped, flow-directed catheter is used almost universally to obtain important diagnostic information at the bedside with a relatively low risk of serious complications. The flexibility of the catheter and the protection of the catheter tip with the inflated balloon as it passes through the heart chambers have contributed to the low incidence of complications associated with cardiac arrhythmias. Although serious complications are rare, they have been reported to occur. It should always be kept in mind that this technique is an invasive one and can be potentially dangerous. Most of the complications associated with flow-directed catheters can be avoided, however, if they do occur the user should be able to recognize the problem immediately and correct it if possible.
