Ultrasound Guidance for Heart Block
(CONDUCT USe Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if ultrasound can make pacemaker lead placement in the heart safer and more effective. Typically, x-rays guide the pacemaker leads, often resulting in longer procedures and increased radiation exposure. Ultrasound may allow doctors to pinpoint the exact spot in the heart for lead placement, potentially reducing both procedure time and radiation risks. The study seeks individuals who need a pacemaker due to conduction tissue disease and have good imaging quality from routine heart scans. As an unphased trial, it offers participants the chance to contribute to innovative research that could enhance future pacemaker procedures.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinator or your doctor.
What prior data suggests that using ultrasound for pacemaker lead implantation is safe?
Studies have shown that conduction system pacing, like the method used in this trial, is generally safe for patients. Research indicates that this approach can help avoid some risks linked to traditional pacing methods, such as reducing the chance of developing heart problems caused by pacing.
Reports on the safety of conduction system pacing, which includes using ultrasound guidance, show that it doesn't increase the risk of hospital visits for heart issues. This suggests that using ultrasound to guide the placement of pacemaker leads in the heart is well-tolerated. Although the trial itself doesn't specify safety details, testing this approach suggests confidence in its safety for participants.12345Why are researchers excited about this trial?
Researchers are excited about using ultrasound guidance for heart block treatment because it offers a new way to place pacing leads more precisely. Unlike conventional methods that rely on X-rays and fluoroscopy, ultrasound allows doctors to directly visualize the lead as it is placed into the heart's septum, reducing the risk of perforation. This technique could improve the accuracy of lead placement and potentially enhance the effectiveness and safety of heart pacing procedures.
What evidence suggests that using ultrasound for pacemaker lead implantation to the LBBA could be effective?
Research has shown that using ultrasound to place pacemaker leads increases accuracy and safety. In this trial, participants in the "US guided" arm will benefit from ultrasound guidance during the procedure. Studies have found that conduction system pacing, particularly in the left bundle branch area (LBBA), yields better results than traditional methods. Specifically, it can reduce the risk of death or hospitalization for heart failure. Ultrasound enables doctors to see the exact placement of the lead, resulting in fewer attempts and reduced risk. This may lead to shorter procedures and less radiation exposure for patients. Overall, early evidence suggests that using ultrasound for this procedure is a promising approach.678910
Are You a Good Fit for This Trial?
This trial is for patients with various types of heart block, such as Bundle-Branch Block and Atrioventricular Block. It's specifically looking at those who need pacemaker lead placement in the left bundle branch area (LBBA) of the heart. The study aims to include individuals who can benefit from a potentially safer and more accurate implantation method using ultrasound instead of X-rays.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Novel Approach to Conduction System Pacing with Use of Ultrasound
Trial Overview
The trial is testing whether using ultrasound guidance for pacemaker lead implantation into the LBBA is better than the traditional fluoroscopy (X-ray) guided method. It seeks to determine if ultrasound can reduce procedure time, improve accuracy, decrease radiation exposure, and ultimately provide better patient outcomes.
How Is the Trial Designed?

Experimental Treatment
Active Control
Patients randomized to this arm will have use of ultrasound in venous access and particularly in attempts to place the pacing lead in the septum at the region of LBBA. This will allow the lead to be directly visualized as it is being passed deep into the septum without perforation and it ensure that the lead is perpendicular to the septum.
Normal deployment of left bundle branch area pacing with use of xrays and fluoroscopy. No use of ultrasound in the procedure.
