What It Is
The porous tip endocardial lead is a cardiac pacing device designed to be implanted in the heart for permanent atrial or ventricular pacing. It features a porous tip mesh electrode that enhances pacing and sensing thresholds, with a screw-in mechanism for secure endocardial fixation.
Clinical Applications
This device is commonly used in patients requiring permanent cardiac pacing, particularly in scenarios where stable long-term pacing thresholds are critical. It is suitable for both atrial and ventricular applications.
Evidence Summary
The literature includes five studies, primarily from the 1980s, involving various study designs. These studies collectively report on the device's performance in terms of pacing thresholds and safety.
Reported Outcomes
Published studies report that the porous tip endocardial lead achieves low chronic stimulation thresholds and maintains threshold stability over time. One study noted a mean pulse width threshold of 0.0534 ms 24 hours post-implantation, with minimal variation over six months.
Safety Profile
Reported complications include a low incidence of electrode repositioning due to exit block. Overall, the device demonstrates a favorable safety profile with no significant adverse events reported in the studies.
Evidence Limitations
The evidence is limited by the age of the studies, with most data originating from the 1980s. There is a need for more recent research to validate these findings in contemporary clinical settings.
