Abstract
The presence of a specific deformity of the right ventricle in association with the double-chambered right ventricle (DCRV) has been discovered in 8 of 14 individuals undergoing detailed study for DCRV. Investigational study employ ing multiple angiographic projections with selective angiography has allowed precise morphological identification of this deformity as a contractile pouch located arising from the outflow tract of the right ventricle. Comparison of the angiographic data with the electro-vectorcardiographic findings of DCRV sug gests that these highly specific electrical features of DCRV correlate with the position and location of the contractile pouch.
