• Video 1 - Video 1 (.rm format). Visual evidence of ventricular twist, as apex is fixed with OPCAB device.
• Video 2 - Video 2 (.rm format). Dense MRI images showing the intraventricular twisting motion during ejection and filling. Please note the intramyocardial twisting toward the apex in the free LV wall and apex regions. Courtesy of Han Wen PhD at NIH, who retains the rights for this video.
• Video 3 - Video 3 (.rm format). Sequential preferential enlargement of Ventricle [v], and Bulbo conus [c] in chick embryo, simultaneously defining the cardiac twist to fold the right side of the ventricle [r] over the left [l] side, and move the atrium [a] cephlad toward its ultimate position.
• Video 4 - Video 4 (.rm format). Sequential strain pattern, using the 3D dense vector fields, showing strain starting at the base, extending to the base on the opposite side, and then moving toward the apex in a spiral motion.
