Pitfalls in the Application of Residual Coronary Pressure Gradient (RCPG) as an Indicator of Success or Failure of Transluminal Coronary Balloon Angioplasty

Heineman Medical Research Laboratory, Charlotte Memorial Hospital and Medical Center, Charlotte, North Carolina

While the measurement of residual trans-stenotic coronary pressure gradi ent (CPRG) in the course of balloon angioplasty is a procedure of practical value in both estimating the severity of the stenosis and the degree of improve ment achieved, its application, however, has also several and serious sources of error; therefore, its value is limited and it should never be accepted as an out-of- context single indicator to either the degree of the stricture or of the anatomic improvement induced by angioplasty.
