What is a characteristic feature of the transcatheter pacing system?

A transcatheter pacing system is recognized for its innovative approach to pacing, particularly its design which allows for a fully self-contained mechanism without the need for traditional leads that are typically used in pacing systems. This characteristic allows for a less invasive procedure compared to conventional pacing methods that require the insertion of leads into the heart through a surgical approach. The self-contained aspect makes it advantageous for patients who might be at higher risk for complications associated with lead placement, as well as in situations where conventional pacing methods may not be feasible.

The transcatheter pacing system can be implanted via a minimally invasive procedure, which significantly reduces recovery time and potential complications associated with surgeries that involve open-heart procedures. Therefore, this feature highlights the flexibility and adaptability of the pacing system in various clinical settings, making it a preferable option in many cases.

In contrast, the other choices involve aspects that either do not match the core functionality of a transcatheter pacing system or misinterpret its application and benefits. For example, the mention of open-heart surgery is not applicable to transcatheter systems, which are specifically designed to avoid such invasive approaches.
