Abstract

Current techniques for left ventricular (LV) lead implantation in patients with ischemic cardiomyopathy (ICM) typically underutilize information which is important for optimal lead location, including LV mechanical activation pattern and scar location. We sought to develop a technique in which this information, contained in single-photon emission computed tomographic (SPECT) images, could be integrated as to guide the electrophysiologist during the implantation procedure. Five ICM patients underwent SPECT as well as multidetector cardiac computed tomographic (MDCT) imaging prior to the LV lead implantation procedure. Images were merged to create a "fusion" image, in which the SPECT data were projected onto the anatomically accurate MDCT epicardial surface. The fusion image was registered to the operative field using the coronary veins, apparent on the MDCT image, as a fiducial system. After registration, LV lead implantation was guided by the fusion image using a commercial catheter navigation system. Successful guidance was achieved in each patient, with minimal disturbance to standard workflow. Leads were implanted in late-activating, unscarred regions according to the fusion image, with locations corroborated by fluoroscopic...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.
