The problems and the causes in viable myocardial detection

Viable myocardial detection is very important in clinical practice. But the positive predictive value and specificities of all imagining modalities available are still relatively lower, and the causes may relative to the smooth of native or bridge coronary arteries after operation, the time to assess the function of viable myocardium, myocardial ischemia or damage after operation, the severity of left ventricular modification before revascularization and subendocardiac muscle scarring formation. The problems of viabile myocardial detection were still discussed here.
