Novel application of 3-dimensional real-time cardiac imaging to guide stem cell-based therapy

Stem cell-based therapy is an emerging treatment for refractory ischemic cardiomyopathy. The transendocardial approach represents the most attractive method that allows direct percutaneous injections of the cell product into the ischemic territories. This clinical case shows a novel strategy designed to optimize cell endocardial delivery, based on the implementation of the 3-dimensional electroanatomical map with the intracardiac-echocardiographic reconstruction of the left ventricle, using acquired multiple slice recordings. Combined imaging was efficacious to detail the anatomical and functional characteristics of the target areas and to guide cell delivery supported by direct real-time visualization of the needle to improve procedural effectiveness and safety.
