iVe report our initial experience using digital subtraction angiography (DSA) techniques for cardiac evaluation. DSA of the heart may be performed with intravenous or right atrial injection of contrast medium (IVDSA) and with left ventricular or aortic root contrast injection (lADSA). The right ventricle and the atria are best demonstrated by IVDSA, while the left ventricle and coronary arteries are best demonstrated by lADSA. The advantages and disadvantages of DSA ofthe bean are discussed. Present equipment limitations restrict the routine use of cardiac DSA, but these should be overcome with advances in technology.
