BACKGROUND: In arrhythmogenic right ventricular disease it is difficult to find an imaging technique not only to suppose but to diagnose this disease. PATIENTS AND METHOD: In order to assess the value of selective right ventricular angiography in 104 patients with arrhythmogenic right ventricular disease (n = 53), WPW-syndrome (n = 2), sarcoidosis (n = 1), atrial septum defect (n = 8), dilative cardiomyopathy (n = 8), mitral valve disease (n = 17) and normal patterns (n = 15) right ventricular angiography was performed in biplane 30 degrees RAO/60 degrees LAO projection. Quantitative criteria such as RVEDVi, RVEF, regional wall motion in infundibular, inferior, apical and anterior segments and qualitative criteria such as deep horizontal fissures in trabecular hypertrophy, "pile d'assiettes" phenomenon and enddiastolic bulges with loss of trabecular structure were analysed. RESULTS: After extensice statistical analysis enddiastolic bulges with loss of trabecular structure and in less circumstance segmental contraction impairment of the right ventricle are the most valuable angiographic signs in order to diagnose ARVD. CONCLUSION: The best definition of arrhythmogenic right ventricular disease is obtained by extensive angiographic analysis with measurement of oxygen saturation and pressure curves in different positions, coronary angiography and biventricular angiography in order to distinguish between some in regard to right ventricular involvement similar cardiac entities.
