Abstract

Objective: Determine if ventricular septum structure and function relationships parallel the left ventricular free wall descending and
ascending segments of the helical heart. Methods: Forty pigs (30—38 kg) were studied physiologically by sonomicrometer to determine if septal
fiber orientation resembled responses in the free wall. Following pilot studies in the non-bypassed heart, a right ventriculotomy was made to
place septum crystals with fiber orientations that were either perpendicular to or reflected simultaneous free wall measurements. Postbypass
measurements tested responses to positive (dopamine) and negative (esmolol) inotropic agents.
