False positive results in right coronary artery areas of myocardial perfusion spect in patients with left bundle block and left ventricular dilatation
Öz
SUMMARY
Objective: The aim of this study is to determine the diagnostic value of myocardial perfusion SPECT (MPSPECT) images in patients with complete left bundle branch block (LBBB) and left ventricular (LV) dilatation.
Method: 25 patients (16 female and 9 male whose mean age 68.2 ± 7) with complete LBBB and LVdilatation have been included in this study. 17 patients who have no typical scintigraphic perfusion abnormality have been evaluated as a control group. LV was divided into segments on the apical, mid and basal short-axis images, and visual perfusion scoring was performed on 1248 segments. Perfusion defects were classified as fixed or reversible. All demographic data and the ejection fraction (EF) values of patients were expressed as average standard deviation. The relation between myocardial perfusion and coronary angiography (CAG) results were evaluated.
Results: In 25 patients who had coronary angiography, the positive diagnostic value of
MPSPECT for left anterior descending coronary artery (LAD) stenosis was 36%, for left circumflex coronary artery (LCx) stenosis was 43%, and for right coronary artery (RCA) stenosis was 16%. Specificity values were 36%, 82% and 13% respectively.
Conclusion: Pharmacologic stress-rest MPSPECT imaging with dipyridamole in the same day increases diagnostic accuracy for detection of coronary artery disease (CAD) in patients with LBBB and LV dilatation. It should be considered that false positive ischemic results detected in RCA areas except for LAD areas in these patients also.

ÖZET
Amaç: Bu çalışmanın amacı komplet sol dal bloğu (LBBB) ve sol ventrikül (LV) dilatasyonu bulunan hastalarda miyokart perfüzyon SPECT (MPSPECT) görüntülemenin tanısal değerini belirlemektir.
Yöntem: LV dilatasyonu ve LBBB bulunan 25 hasta (16 kadın, 9 erkek, yaş ortalaması: 68,2 ± 7 yıl) incelendi. Kontrol grubu olarak tipik sintigrafik perfüzyon anomalisi saptanmayan 17 hasta alınmıştır. Apikal, orta ve bazal kısa eksen görüntüleri üzerinde LV segmentlere ayrıldı ve 1248 segmentte vizüel perfüzyon skorlaması yapıldı. Perfüzyon defektleri sabit veya reversibl olarak sınıflandırıldı. Hastaların tüm demografik verileri ile EF değerleri ortalama±standart sapma olarak ifade edildi. Perfüzyon değişiklikleri ile koroner anjiografi (KAG) sonuçları arasındaki ilişki değerlendirildi.
Bulgular: Koroner anjiografileri yapılan 25 hastada MPSPECT’in pozitif tanı değeri; sol ön inen koroner arter (LAD) stenozu için %36, sol sirkümfleks arter (LCx) stenozu için %43 ve sağ koroner arter (RCA) stenozu için %16 idi. Spesifisite değerleri sırasıyla %36, %82 ve %13 idi.
Sonuç: Bu hastalarda LAD alanı haricinde RCA alanında da yanlış pozitif iskemi saptanabileceği göz önünde bulundurulmalıdır. Ayrıca LBBB ve LV dilatasyonu bulunan hastalarda koroner arter hastalığının (KAH) saptanmasında dipiridamol ile farmakolojik stres testinin, istirahat-stres Tc-99m MIBI MPSPECT görüntüleme protokolü ile aynı gün uygulanması tanısal doğruluğu arttırmaktadır.
