VVV
Study Basics
VVV
is a Trial of Variability of Echocardiographic
Left Ventricular Mass, Volume
and Ejection Fraction in Pediatric Patients with Congestive
Cardiomyopathy. The short title for the study is VVV.
are the primary method to evaluate the size of the heart and
how it functions. At the present time, healthcare providers
do not know how reproducible some of the measurements are,
especially in children. This study was done to help us understand
why there might be errors in measurements and the true change
in heart function values over time. The study began on May
16, 2005 and the last patient was enrolled in July 2007 with
131 individuals enrolled.

What happened during
the study?
Each qualified
person had data collected on labs, tests and procedures that
were done as part of routine clinical care. A second set of
measurements were done when each routine echocardiogram was
performed during a one year period of time (with at least
3 months in between each test).

What were the results of
the study?
As of now, this
study has finished enrolling patients but some patients are
still being followed. Until all patients have completed the
follow-up period, results will not be available. It is thought
that the follow-up will end in late 2008.
