Two-point left ventricle pacing and cardiac computed tomography.

Area of Science:

• Cardiovascular Imaging
• Medical Device Technology

Background:

• Endocardial leads are crucial for cardiac function but can cause artifacts in medical imaging.
• Artifacts from endocardial leads may impede visualization of coronary vessels during multislice computed tomography (MSCT).

Purpose of the Study:

• To evaluate the feasibility of performing MSCT of coronary arteries in patients with multiple endocardial leads.
• To assess the impact of endocardial leads on coronary vessel visualization using MSCT.

Main Methods:

• Case study involving multislice computed tomography (MSCT) imaging.
• Analysis of image quality and artifact presence during coronary vessel and endocardial lead visualization.

Main Results:

• Successful visualization of coronary arteries was achieved despite the presence of four endocardial leads.
• Artifacts generated by the endocardial leads did not completely obscure coronary vessel imaging.

Conclusions:

• Multislice computed tomography (MSCT) is a viable imaging modality for coronary arteries even with multiple coexisting endocardial leads.
• Careful technique and interpretation can overcome imaging challenges posed by endocardial leads in MSCT.
