Chamber dilatation in 8 month old male transgenic mice
Formaldehyde fixed hearts, both control (A and C) and 140 line transgenic (B and D), were bisected axially by an incision through the anterior face of the left ventricle. The two halves of the heart were splayed open to reveal the left ventricular cavity (C and D). In this position, the atria are hidden behind the two halves of the heart, the left ventricular free wall is distal and the right ventricular free wall is medial to the vertical axis.
