SPECT-Guided LV Lead Placement for Incremental CRT Efficacy

Pre-Implant Assessment For Optimal LV Lead Placement In CRT: ECG, ECHO, or MRI?

Cardiac resynchronization therapy (CRT) improves cardiac function in many patients with ventricular dyssynchrony. The optimal use of imaging for pre-implantation assessment remains a subject of debate. Here, we review the literature to date on the utility of echocardiography and cardiac MR, as well as conventional ECG, in choosing the best site for LV lead implantation. Prior to the use of imag...

3D fusion of LV venous anatomy on fluoroscopy venograms with epicardial surface on SPECT myocardial perfusion images for guiding CRT LV lead placement.

OBJECTIVES The aim of this study was to develop a 3-dimensional (3D) fusion tool kit to integrate left ventricular (LV) venous anatomy on fluoroscopy venograms with LV epicardial surface on single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) for guiding cardiac resynchronization therapy (CRT) LV lead placement. BACKGROUND LV lead position is important for CRT...

Echocardiography-Guided Left Ventricular Lead Placement for Cardiac Resynchronization Therapy: Results of the Speckle Tracking Assisted Resynchronization Therapy for Electrode Region (STARTER) Trial Saba et al: Echo-Guided LV Lead Placement in CRT

Real-time CT-guided percutaneous placement of LV pacing leads.

OBJECTIVES The aim of this study was to assess the feasibility of real-time computed tomographic (CT) imaging to guide the percutaneous placement of left ventricular (LV) leads in an animal model. BACKGROUND Cardiac resynchronization therapy has been shown to improve morbidity and mortality in patients with chronic heart failure. However, placement of the coronary sinus lead can be challengin...

A new method for accurate localization of the LV pacing lead from fluoroscopy images to MRI images: application to studies involving lead placement and CRT

Background In Cardiac Resynchronization Therapy (CRT), studies examining the importance of placing the LV pacing lead in the latest contracting segment have produced conflicting results. Some studies have shown higher response rates when the lead is placed in the latest contracting segment, while others show no relationship between lead placement and response. All of these studies relied on sub...
