Clinical Study

Perfusion Imaging In Incomplete Left Bundle Branch Block

Posted Date: May 22, 2021

  • Investigator: Myron Gerson
  • Specialties: Cardiology, Heart Disease
  • Type of Study: Observational/Survey

Complete left bundle branch block can produce septal artifacts on myocardial perfusion scans, an effect that is made worse by elevated heart rate. Therefore pharmacologic stress is strongly recommended rather than treadmill exercise for stress perfusion studies. It is not known whether similar artifacts occur in the presence of incomplete left bundle branch block (iLBBB). In addition, little is known concerning the prognostic implications of incomplete left bundle branch block. The present study compares the prevalence of septal perfusion defects with SPECT myocardial perfusion imaging in patients with iLBBB and no angiographic left anterior descending (LAD) coronary artery disease to patients without iLBBB and no angiographic coronary disease. It also compares mortality in patients with iLBBB to a control population of patients referred for SPECT imaging who go on to coronary arteriography.
