Angiographic projections

  1. 1. ANGIOGRAPHIC PROJECTIONS
  2. 2. NOMENCLATURE OF ANGIOGRAPHIC VIEWS • AP position • RAO position • LAO position • Cranial position • Caudal position
  3. 3. ANGIOGRAPHIC VIEWS FOR SPECIFIC CORONARY ARTERY SEGMENTS • Left Main AP LAO cranial LAO caudal • Proximal LAD LAO cranial RAO caudal • Mid LAD LAO cranial RAO cranial Lateral • Distal LAD AP RAO cranial Lateral • Diagonal LAO cranial RAO cranial
  4. 4. • Proximal circumflex RAO cranial LAO caudal • Intermediate RAO caudal LAO caudal • Obtuse marginal RAO caudal LAO caudal RAO cranial • Proximal RCA LAO Lateral • Mid RCA LAO Lateral RAO • Distal RCA LAO cranial Lateral • PDA LAO cranial • Posterolateral LAO cranial RAO cranial
  5. 5. DEGREE OF ANGULATION • Left Coronary Artery LAO - 300 - 450 Cranial - 200 - 300 Caudal - 200 - 300 RAO - 300 - 450 • Right Coronary Artery LAO - 300 - 450 Cranial - 150 - 200 RAO - 300 - 450
  6. 6. COMMON ANGIOGRAPHIC VIEWS OF CONGENITAL HEART DISEASE • Biplane cineangiography is require • For VSD LAO - 500 – 600 Cranial - 200 – 300 • For ASD (Hepatoclavicular angiographic view) LAO - 500 – 600 Cranial - 200 – 300
  7. 7. • For transposition of great arteries(Laid back angiographic view) Steep AP caudal - 350 • Proximal branch pulmonary artery anatomy Steep AP cranial - 350
  8. 8. Causes of Poor Angiograms • PATIENT FACTORS Size Movement Hardware (Pacemaker, Harrison rods, multiple surgery with clips) • Angiographer Factors Poor catheter seating Poor contrast injection • Equipment Factors X-ray generated problem X-ray tube problem Image intensifier problem
