ANGULATED VIEWS IN THE SAGITTAL PLANE FOR IMPROVED ACCURACY OF CINECORONARY ANGIOGRAPHY

We have found that these difficulties can be overcome, in most instances, by the systematic use of additional views in a sagittal plane, angulated approximately

Scholarcy highlights

  • I N recent years, the diagnostic contnibution of selective coronary arteniography has been considerable and its importance has been fully acknowledged
  • Discrepancies between the angiognaphic data and subsequent pathologic findings are frequent, when lesions are located near the bifurcation of the left coronary artery
  • Supenimpositions ofvessels not infrequently occur in all standard transverse angiographic projections and stenoses can be overlooked on underestimated
  • States Catheter and Instrument verse or horizontal projections of both coronary arteries can be and rapidly obtained. These projections include a frontal, true lateral, 30#{176r}ight anterior oblique and 5#{176t}o 600 left anterior oblique view. In this standard transverse or horizontal plane of rotation, the x-ray beam is perpendicular to the longitudinal axis of the rnidd!e and distal segments of the left coronary artery
  • The occurrence of angina pectonis with normal coronary arteries has been recognized for several decades
  • Relative or functional mvocardial ischemia can be induced by severe anemia, aortic and systemic hypertension.7 valvular More disease recently, extensive use of selective coronary arteriographv has led to the identification of patients or groups of patients with angina pectoris or mvocardial infarction and normal coronary arteniograms
