The role of noninvasive cardiac imaging in the evaluation of the postcoronary intervention patient.
Noninvasive diagnostic techniques are playing an increasingly prominent role in the evaluation of the postcoronary interventional patient.  Radionuclide myocardial perfusion imaging has proved to be of value in assessing procedural success in patients with suboptimal angiographic results and/or multivessel coronary artery disease.  However, in asymptomatic patients with single vessel disease, the use of myocardial perfusion imaging may not be cost-effective for follow-up after successful coronary intervention.  The timing of these studies is important when used to predict coronary restenosis.  Radionuclide ventriculography and echocardiography are two imaging modalities that, in conjunction with exercise stress, can be used to predict patient outcome and clinical events postcoronary intervention.  A high degree of operator expertise is required for the optimal interpretation of the echocardiographic studies.
