Electromechanical endocardial mapping of the heart using a nonfluoroscopic
catheter-based system is a new imaging modality that has been studied recen
tly in the experimental setting as well as in patients, Besides its origina
l application in the diagnosis and treatment of various cardiac arrhythmias
, it has also been used as an investigational tool for assessing left ventr
icular function and viability. Finally, the mapping system may be a valuabl
e platform for direct myocardial revascularization using either laser treat
ment or injection of pharmacologic agents. Curr Opin Cardiol 2000, 15:337-3
