An ultrasound system comprises a memory for storing patient study data associated with segments of a patients left ventricle (LV). The patient study data comprises at least a first asynchrony study and at least one of a first viability study and a first regional function study. A cardiac resynchronization therapy (CRT) lead placement planning module compares at least a portion of the patient study data for each of the segments. An output device indicates at least one location for placement of an LV lead within one of the segments of the patients LV during a CRT procedure based on the comparison of the at least a portion of the patient study data for each of the segments.
