What is it indicated for?

QLV-CMS provides quantitative information regarding the calculated dimensions and

calculated performance characteristics of the left ventricle of the heart, imaged during

angiographuc x-ray procedures typically performed in cardiac cath labs. This information

is suitable for use by physicians and scientists in the following applications:

1. Scientific and research studies, assessing the angiographic condition of patients and

the results of device and drug therapies,

2. Review and analysis of patient angiographic imaging records, providing additional

information to physicians and administrators.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
