Does selective angiocardiography accurately evaluate valvular insufficiency?
Selective angiocardiography is a highly sensitive method for evaluating valvular insufficiency, though care must be taken to avoid false positives from technical artifacts.
Incompetence of any of the cardiac valves can be easily evaluated by selective angiocardiography. Factitious insufficiency may result from faulty catheter placement or from ventricular extrasystoles caused by the pressure injection of the contrast agent. False negative results are almost nonexistent, and if no insufficiency is seen on a technically adequate angiocardiogram, the valve can be considered to be competent.
