Background: The presence of septal perfusion defect on myocardial perfusion single-photon emission computed tomography (SPECT) in patients with known left bundle branch block (LBBB) can present a major diagnostic dilemma.
Methods: Thirty-nine patients with known LBBB underwent both SPECT and coronary computed tomography angiography (CCTA), a median of 65 days after SPECT. Patients underwent SPECT; CCTA was performed on the basis of abnormal SPECT and presence of clinical symptoms. Exclusion criteria included a history of myocardial infarction, previous coronary artery bypass surgery or percutaneous coronary intervention.
Results : Of the study population (n=39), 22 (56%) patients were female and the mean (± SD) age was 63±13 years; all patients were known to have LBBB diagnosed by electrocardiogram. SPECT results showed 24 (61%) patients had a reversible .. Read More»
