title: [Double nuclide myocardial scintigraphy with thallium 201 and iodine 123-heptadecanoic acid--the possibilities in cardiological diagnosis].
abstract: We studied in 11 patients the individual variable pattern of coronary blood supply after the end of diagnostic coronary catheterisation by intracoronary injection of T1201 into the left and J 123-heptadeconic acid into the right coronary artery. In 4 static views computer aided quantitative analysis of circumferential profiles was performed. Based on Schlesinger's criteria three types of coronary arterial patterns were defined (right, left preponderant, balanced) after the presentation in the angiographic projections.
  
  
  CONCLUSIONS
  Sharp boders between different perfusion areas could be detected by the gamma camera. If patients with right preponderant circulation are compared with balanced circulation, the perfusion areas of the left coronary artery are greater in all cases with balanced circulation than expected. More important for the indication of coronary artery surgery is that a considerable area of the left ventricular myocardium is perfused by the right coronary artery independent of the anatomical perfusion pattern with the exception of the left preponderant type.
